What is the difference between 7075 and 7050 aluminum alloy?

7050 aluminum alloy is based on 7075 aluminum alloy and increases Zn, Cu content, and Cu/Mg ratio to increase strength and replaces Cr with Zr to overcome quenching sensitivity problem and inhibit recrystallization, which has higher strength, fracture toughness, and stress corrosion resistance. Now NOBLE Smart Editor to give you a little.

7075 aluminum alloy: 7075 aluminum alloy is a cold treatment forging alloy, has high strength, and is far better than soft steel. 7075 is one of the most powerful alloys for commercial use. 7075 aluminum alloy has a tight structure and strong corrosion resistance and is best for aviation and marine plates. General corrosion resistance, good mechanical properties, and anodic reaction. Fine grains make better depth drilling performance, tool wear resistance is enhanced, and thread rolling is more distinctive. 7075 aluminum alloy tensile strength 524Mpa, 0.2% yield strength 455Mpa: elongation 11%, modulus of elasticity E/Gpa: 71, hardness 150HB, density: 2810.

7050 aluminum alloy: 7050 aluminum alloy is a high-strength heat treatable alloy with high strength and resistance to spalling corrosion and stress corrosion fracture. The main alloy element of 7075 series aluminum alloy is zinc, adding magnesium to the alloy containing 3%-75% zinc can form MgZn2 with a significant strengthening effect, which makes the heat treatment effect of this alloy far better than that of aluminum-zinc binary alloy. By increasing the zinc and magnesium content of the alloy, the tensile hardness will be further increased, but the resistance to stress corrosion and spalling corrosion will be reduced. After heat treatment, very high strength characteristics can be achieved.

Why choose aluminum alloy as the material for CNC machining?

Nowadays, aluminum alloy is very widely used in today's society, and at the same time, CNC milling is also, various products that people use are processed in the CNC milling process. Among all CNC milling, aluminum alloy is one of the most used materials. Because it has a lot of advantages, so today Noble says why we will choose aluminum profiles to produce CNC milling parts.

First of all, aluminum itself is a light, non-magnetic silver metal, it can form almost any shape of metal parts. Aluminum is the third most abundant element in the earth's crust, after oxygen and silicon, and it is a relatively new industrial metal. That's why we chose it.

What are the advantages of using aluminum for CNC milling parts?

1. It is non-toxic, requires less heat than stainless steel or cast iron, and heats quickly and evenly.

2. Aluminum helps build buildings that are corrosion-resistant and low maintenance, and aluminum products are used in new construction and renovation.

3. The combination of light weight, strength, and ductility make aluminum CNC milled parts ideal for transportation applications.

    Aluminum CNC machining, also known as computer gong machining or CNC machine tool machining, is mainly done from aluminum parts and cases. In recent years, with the rise of cell phones, computers, chargers and auto parts, there is a demand for improved accuracy of aluminum parts Machining, but the other side has made a leap in the quality of aluminum CNC machining process to achieve high volume, high precision aluminum production. Next, Shenzhen Noble will introduce the advantages of CNC machining of aluminum alloy in detail for you. Aluminum alloy spare parts Machining

Finished and semi-finished aluminum alloy Machining in several ways.

Modern aluminum alloy Machining methods include semi-finished aluminum alloy Machining and finished aluminum alloy Machining. Then what are the several ways of aluminum alloy machining?

There are three kinds of finished finished aluminum alloy Machining.

1、The extrusion of aluminum alloy Machining. We use the extrusion method to make the mold, and the aluminum ingot is extruded through the mold by the compressor. We make good molds to process aluminum alloy in small quantities to meet the needs of customers.

2、Aluminum alloy Machining straightening. The straightness of aluminum alloy Machining needs to be straightened by straightening instrument, which needs to reach the industry standard and meet the daily needs.

3、Oxidation post-treatment of aluminum alloy Machining. After the aluminum alloy is tested and qualified, the aluminum alloy needs to be oxidized before it can be used, so that it is beautiful and resistant to corrosion and wear.

There are four kinds of finished aluminum alloy Machining

1、Cutting of aluminum alloy Machining. We usually use one normal aluminum profile of 6.02 meters, but in actual production and application, we need to combine various aluminum alloy length specifications together, so we need to cut as required to ensure the cutting length and accuracy of aluminum alloy.

2、Punching hole of aluminum alloy Machining. Industrial aluminum alloy installation is usually a combination of multiple aluminum profiles with different specifications and accessories, and the connections need to have pre-buried holes, and the holes here need to be operated by professional punching machine according to the design requirements.

3、Tapping of aluminum alloy Machining. Industrial aluminum profiles, accessories and connections are inevitably combined with bolts and nuts, screws, etc., which need to be tapped.

4、Milling slot of aluminum alloy Machining. In order to make the later assembly of other spare parts convenient, we usually need to milling grooves on the surface of aluminum alloy to ensure the assembly of other spare parts and save work efficiency.

Aluminum alloy Machining using CNC machine tool operation steps?

The working steps of CNC machine tools

  In the CNC machine tool Machining parts to go through the following steps for.

(1) Preparation stage

4. Stronger strength, advanced equipment and excellent talents, Machining a wider range of sizes and producing better prototypes.

The working principle of CNC machining of aluminum alloy What are the advantages of aluminum alloy machining?

First, the principle of aluminum alloy CNC machining:

Aluminum CNC machining principle is to use the automatic control system to install digital program process command to control the automatic start and stop of CNC machine tool bearings. CNC inserts can be selected according to the CNC inserts, change the amount of tool eating and walking trajectory, to complete a lifetime of Machining required for a variety of auxiliary actions.

Second, aluminum alloy CNC machining advantages.

1. CNC machining of aluminum alloy can greatly reduce the total number of tooling, production and Machining style of complex parts, only need to change the Machining technology.

2. CNC machining of aluminum alloy is relatively stable and will not cause manual Machining deviation, resulting in different and even inferior products for each aluminum alloy.

3. Aluminum alloy CNC machining can produce complex aluminum parts, and even produce machined parts. It can also produce a variety of varieties, high production efficiency, saving labor costs, while achieving diversified production.

Three, aluminum alloy CNC machining features.

1. Low hardness of aluminum alloy

Compared with titanium alloy and hardened steel, aluminum alloy has a lower hardness, of course, heat treatment or die-casting aluminum alloy also has a higher hardness. The general HRC hardness of aluminum plate is generally below HRC40 degree. Therefore, in the case of machining aluminum alloys, the load on the tool is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed.

2. Low plasticity of aluminum alloy

Aluminum alloy has low plasticity and low melting point. When machining aluminum alloy, the bonding edge problem is deep, the chip removal performance is poor, and the surface roughness is high. In fact, when machining aluminum alloy, it is mainly the knife and roughness effect is not good. If the two problems of fixed knife edge and quality of Machining surface are solved, the problem of machining aluminum alloy can be solved.

3. The tool is easy to wear

Because of the use of unsuitable tool material, in the case of machining aluminum alloy, there are more cases that the tool wears faster due to the problems of bar edge and chip discharge.

What are the processes for Machining aluminum alloys?

Aluminum alloy can be obtained by adding other metals, such as silicon, iron, copper, and aluminum. It is characterized by low density, high strength and high corrosion resistance. Its light weight and high strength make aluminum alloy profiles widely used in the Machining and manufacturing of various parts. What are the Machining processes of aluminum alloy?

1、Aluminum alloy stamping Machining method.

Stamping is a molding method in which plates, strips, tubes and profiles are deformed or separated by applying force to them using a press and die to obtain the desired shape and size. Stamping is a process in which parts of a product with a certain shape, size, and performance are processed by using the force of ordinary or specialized stamping equipment to subject the workpiece directly to the deformation force of a die. The three major elements of stamping are the metal plate, the die, and the equipment. Forming is a method of metal Machining that involves cold deformation, also known as cold stamping or sheet metal stamping. It is the main method of metal plastic Machining.

2、Aluminum alloy precision casting Machining.

Precision casting is a special kind of casting. The parts obtained by this method generally do not need to be processed. Such as investment casting, die casting, etc. The general practice is: first design and manufacture a mold according to the product requirements (can be very small or no margin), use the casting method to cast wax to obtain the original wax mold; repeat the process of painting, sanding, hardening and drying the wax mold; dissolve and dewax the inner wax mold to obtain the mold cavity; bake the mold to make it sufficiently strong; pour the required metal materials, de-shell and clear the sand to obtain high-precision finished products; heat treatment, such as Heat treatment, such as heat treatment, cold working, etc. The heat treatment, such as heat treatment and cold Machining, is carried out according to the product requirements.

3、Powder Machining of aluminum profiles.

Powder manufacturing refers to the creation of metallic powder, which is made into materials or products through the process of mixing, molding, sintering and other industrial processes. There are two points:

(1) The manufacture of metallic powder (including alloy powder), hereinafter referred to as "metallic powder".

(2) Metallic powder (sometimes a small amount of non-metal powder) can be made into various materials (so-called "powder metallurgical materials") or various materials (sometimes "powder metallurgical products") after mixing, forming and sintering.

4、Aluminum alloy injection molding.

The organic binder is mixed with solid powder, granulated, heated with an injection molding machine in a plasticized state (~150℃), removed from the binder by chemical or thermal decomposition methods, sintered and compacted, and the finished product is obtained.

5. Aluminum alloy parts injection molding.

The solid powder is mixed with organic binder evenly, granulated and injected into the mold cavity by injection molding machine in the plasticized state (~150℃) under heating, then the binder is removed from the molding blank by chemical or thermal decomposition method, and the product is obtained by sintering and densification. Compared with the traditional process, it has the characteristics of high precision, uniform organization, excellent performance and low production cost. Its products are widely used in industrial fields such as electronic information engineering, biological medical devices, office equipment, automobiles, machinery, hardware, sports equipment, watch and clock industry, weapons and aerospace.

What is the process of CNC machining of aluminum alloy?

With the development of the times, industrial aluminum profiles generally refer to all aluminum profiles other than those for building doors and windows, curtain walls, indoor and outdoor decoration and building structures. Aluminum profile Machining process contains three full processes of melting, extrusion and coloring (coloring key contains: oxidation, electrophoresis process, fluorocarbon spraying, electrostatic powder coating, wood grain transfer, etc.). What are the aluminum profile Machining processes?

First, the dissolution of refining is the first process of aluminum profile Machining and manufacturing.

(1) Blending: According to the actual aluminum alloy model that must be produced and manufactured, the amount of various aluminum alloy components plus is measured, and various raw materials are effectively matched.

(2) Smelting: The selected raw materials are added to the melting furnace to melt according to the Machining technology, and the miscellaneous slag and vapor in the melting body are reasonably removed according to the de-gassing and slagging refining method.

(3) Forging: The smelted lithium bromide solution is cast into various specifications of round cast bars under certain forging process standards and refrigeration according to the software of deep water well forging system.

Second, extrusion is the second process of aluminum profile Machining.

Extrusion is the way of aluminum profile Machining and forming. First, according to the cross-sectional design plan of profile goods, production and manufacture of grinding tools, the use of extrusion machine will be heated good round casting bar from the grinding tool extrusion molding. The common model 6063 aluminum alloy, when extruded, also uses an air-cooled heat treatment whole process as well as after the artificial aging whole process to carry out the heat treatment process strengthening. Different models of heat treatable process to strengthen aluminum alloy, its heat treatment process regulations are not the same.

Third, coloring is the third process of aluminum profile Machining.

Anodic oxidation: Anodic oxidation is one of the important steps of aluminum profile Machining. The extruded aluminum alloy profile, whose surface corrosion resistance is not strong, shall carry out surface solution according to anodic oxidation to enhance the corrosion resistance, wear resistance and surface beauty and generosity of the aluminum profile.

(1) Aluminum alloy surface Machining. We usually use organic chemistry or physics to carry out cleaning on the surface of the profile to reveal the pure routine, in order to facilitate the obtaining of detailed and high-density human oxide film. Also able to get mirror glass or no light (matte) surface according to the mechanical equipment way.

(2) Aluminum combined with anodized polar oxidation. After the surface preparation treatment of the profile, under certain Machining process standards, the conventional surface produces anodic oxidation, transforming into a layer of high-density, porous structure, strong adsorption of AL203 film layer.

(3) Grouting reinforcement: the membrane pore porosity of the porous structure oxide film transformed into after anodic oxidation is closed, so that the oxide film pollution management, corrosion resistance and wear resistance is improved. The oxide film is completely transparent without color, and the strong adsorption force of the oxide film before using grouting reinforcement will absorb and accumulate some metal salts in the membrane pores, which can make the surface of the profile present many shades other than the original color (silver), such as: gray-black, copper, orange and stainless steel plate color, etc.

Industrial aluminum profiles are divided into base material, anodized profile, electrophoresis profile, powder coating profile, fluorocarbon paint coating profile, wear strip heat insulation profile, glue injection heat insulation profile, etc. The premise of the production of aluminum profiles is extruded material, round ingots are extruded to change the shape of the profile, in which molds and ingots are used, and molds also need to be designed, and after the design is done is the mold manufacturing, then is the test mold, if it is possible to directly into the warehouse, and finally to the mold heating.

Aluminum production and Machining process, aluminum ingots plus auxiliary materials melt casting, homogenization after the aluminum bar heating, and then put in the mold extrusion, extrusion out of the profile after heat treatment and start surface treatment and also material, need deep Machining on the hole tapping, do not need to directly pack into the warehouse can be.

What are the standards to be observed in the process of aluminum alloy Machining?

What are the standards to be observed in the process of aluminum alloy Machining? The three main characteristics of aluminum alloy Machining Aluminum alloy Machining services include cutting, punching, tapping and so on. If you can't follow the size to process accurately, it will cause the aluminum alloy not to be assembled up. So the standards of aluminum alloy machining are: no smooth surface without roughness, size cutting error within ±0.5mm, tapping and so on should be in line with the drawing size. Then what are the standards that need to be observed in the process of aluminum alloy Machining?

First, aluminum alloy Machining commodity quality control standards.

According to the accumulation of aluminum alloy Machining standards for so many years, the construction aluminum alloy profile fulfills the above specification, that is to say, as long as the aluminum alloy profile used in the construction industry, its goods must be produced and quality control of goods according to GB5237.1~5-2008 ﹑ GB5237.6-2004 mandatory specifications.

Second, aluminum alloy Machining kneading profile standard.

GB/T6892-2006 "commonly used industrial aluminum and aluminum alloy kneading profiles

Industrial aluminum alloy profiles refer to aluminum kneading profiles other than aluminum alloy for construction doors and windows, curtain walls and interior decoration, except for individual commodities to fulfill their special specifications, most of them fulfill the specification GB/T6892-2006 "commonly used industrial aluminum and aluminum alloy kneading profiles", which are mainly used in aerospace, transportation, track vehicles, electronic appliances, sports equipment, radiators, decoration, electric power Power, petrochemical industry, machinery manufacturing and other industrial fields.

Third, the standard of aluminum alloy Machining hot kneading profile.

This latest international standard of aluminum alloy decorative profiles GB/T26014-2010 "Aluminum alloy decorative profiles for non-construction

Non-construction aluminum alloy decorative profiles refer to the decorative aluminum alloy hot kneading profiles with the primary purpose of improving visual effects. The scale error of decorative profiles shall be indicated in the contract if there is special demand. If there is no special demand, it should conform to the rules of general grade in GB/T14846-2008 "Aluminum and Aluminum Alloy Kneading Profile Scale Error". The products are mainly used in the fields of vehicle decoration, home appliance parts, kitchen appliances, electronic appliances, interior decoration, medical equipment, instruments and meters, work equipment and so on.

Fourth, the standard of scale error of kneading profiles for aluminum alloy Machining.

This international standard of the latest kneading profile scale error GB/T14846-2008 "aluminum and aluminum alloy kneading profile scale error

Another specification for industrial aluminum alloy profiles fulfills GB/T14846-2008 "Aluminum and aluminum alloy kneading profile scale error". However, this specification is only for industrial aluminum alloy kneading scale, only the demand for scale can be produced according to this specification. Other needs are all according to GB/T6892-2006 specification.

In the nature, aluminum alloy and aluminum alloy profile are two different materials, and the meaning of aluminum alloy is more general. Its main components are divided into two categories: cast aluminum alloy Machining and deformed aluminum alloy Machining. For different grades, the control requirements of aluminum alloy composition are different.

Aluminum alloy parts Machining five common ways

1、Oxidation post-treatment of aluminum alloy Machining

Because of the strong corrosion resistance of aluminum alloy, it is easy to oxidize, so the surface treatment of aluminum alloy should be carried out to increase the wear resistance and corrosion of aluminum alloy and to meet the good-looking surface of aluminum alloy.

2、Squeezing and forming of aluminum alloy Machining

The required product model is carved out through the mold, and the semi-finished aluminum material is poured into the mold and extruded through the extruder to achieve the desired mold, and then CNC small batch Machining is carried out to meet the manufacturer's order requirements.

3、Casting and forming of aluminum alloy Machining.

Our Noble master will usually melt the good aluminum liquid through the casting technology for the first process of aluminum alloy Machining, casting out the required products.

4、Aluminum alloy Machining of melting out impurities.

Melting in the melting furnace to remove impurities in the process can ensure better performance of the product.

5、The ingredients of aluminum alloy Machining.

When we process the aluminum alloy, the reason why we need to carry out the ingredients is because aluminum itself is a relatively soft material, and we need to add some other things. Aluminum alloy is produced with greater hardness, and we need to configure out materials to match the aluminum to ensure the hardness of aluminum alloy.

Second, the aluminum alloy Machining process needs to pay attention to ten matters

We usually carry out aluminum alloy Machining need to pay attention to, the following is the master of NOB CNC Machining more than ten years of accumulated aluminum alloy Machining experience.

1、When we carry out aluminum alloy Machining, the operator should always order the machine, whether the situation of demoulding, if there is and the situation is not serious, consider stopping to see, and correct to continue aluminum alloy Machining.

2、After receiving the customer's order drawings and requirements, our Nopal aluminum alloy cnc Machining factory will carry out post-treatment such as oxidation and oil spraying on the appearance of aluminum alloy.

3、We also need to consider the wall thickness of aluminum alloy Machining, the thickness gap will be too big for filling.

4、In the structure, we try to avoid the appearance of the structure that leads to the complex structure of the mold, and we have to use more than one core extraction or spiral core extraction.

5、Take into account the mold problem when designing, if there are multiple positions of core extraction bit, try to put both sides, it is better not to put in the lower core extraction, so that the aluminum alloy die-casting lower core extraction will have problems after a long time.

6. At present, there are many unsafe factors in the manipulation system and electrical control system of many obsolete stamping equipment, which should be technically modified if they continue to be used. Stamping equipment manufacturers should improve the product design to ensure the safety and reliability of stamping equipment.

7. For CNC mass production, we can start from reforming aluminum alloy Machining technology and moulds to realize mechanization and automation. For example, we can adopt automatic, multi-station stamping machinery and equipment, adopt multiple planning tools and mechanized production devices, and adopt continuous die and compound die to merge CNC Machining process measures. All these not only can guarantee the safety of stamping operation, but also can greatly improve the production efficiency of aluminum alloy.

8、For us to use small batch CNC Machining, we must install safety guards in the stamping operation which is neither automated nor can use safety stamping tools to prevent the injury accidents caused by the operation errors. Various guards have their own characteristics and scope of use, and injuries can still occur if they are not used properly. Therefore, it is necessary to clarify the role of various protective devices so that they can be used correctly to ensure safe operation.

9、Because of the weak corrosion resistance of aluminum alloy, part of the CNC Machining factory has a humid environment and relatively strong corrosion, which is easy to short circuit and damage the internal components, so do a good job in the process of aluminum alloy Machining to prevent corrosion.

10、We should improve the product design and ensure the safety and reliability of the stamping equipment when using the stamping equipment manufacturer. When aluminum alloy Machining is carried out, once damage occurs, it can be replaced in time to avoid the emergence of defective products.

What are the processes for Machining aluminum alloys?

Aluminum alloy can be obtained by adding other metals, such as silicon, iron, copper, and aluminum. It is characterized by low density, high strength and high corrosion resistance. Its light weight and high strength make aluminum alloy profiles widely used in the Machining and manufacturing of various parts. What are the Machining processes of aluminum alloy?

1、Aluminum alloy stamping Machining method.

Stamping is a molding method in which plates, strips, tubes and profiles are deformed or separated by applying force to them using a press and die to obtain the desired shape and size. Stamping is a process in which parts of a product with a certain shape, size, and performance are processed by using the force of ordinary or specialized stamping equipment to subject the workpiece directly to the deformation force of a die. The three major elements of stamping are the metal plate, the die, and the equipment. Forming is a method of metal Machining that involves cold deformation, also known as cold stamping or sheet metal stamping. It is the main method of metal plastic Machining.

2、Aluminum alloy precision casting Machining.

Precision casting is a special kind of casting. The parts obtained by this method generally do not need to be processed. Such as investment casting, die casting, etc. The general practice is: first design and manufacture a mold according to the product requirements (can be very small or no margin), use the casting method to cast wax to obtain the original wax mold; repeat the process of painting, sanding, hardening and drying the wax mold; dissolve and dewax the inner wax mold to obtain the mold cavity; bake the mold to make it sufficiently strong; pour the required metal materials, de-shell and clear the sand to obtain high-precision finished products; heat treatment, such as Heat treatment, such as heat treatment, cold working, etc. The heat treatment, such as heat treatment and cold Machining, is carried out according to the product requirements.

3、Powder Machining of aluminum profiles.

Powder manufacturing refers to the creation of metallic powder, which is made into materials or products through the process of mixing, molding, sintering and other industrial processes. There are two points:

(1) The manufacture of metallic powder (including alloy powder), hereinafter referred to as "metallic powder".

(2) Metallic powder (sometimes a small amount of non-metal powder) can be made into various materials (so-called "powder metallurgical materials") or various materials (sometimes "powder metallurgical products") after mixing, forming and sintering.

4、Aluminum alloy injection molding.

The organic binder is mixed with solid powder, granulated, heated with an injection molding machine in a plasticized state (~150℃), removed from the binder by chemical or thermal decomposition methods, sintered and compacted, and the finished product is obtained.

5. Aluminum alloy parts injection molding.

The solid powder is mixed with organic binder evenly, granulated and injected into the mold cavity by injection molding machine in the plasticized state (~150℃) under heating, then the binder is removed from the molding blank by chemical or thermal decomposition method, and the product is obtained by sintering and densification. Compared with the traditional process, it has the characteristics of high precision, uniform organization, excellent performance and low production cost. Its products are widely used in industrial fields such as electronic information engineering, biological medical devices, office equipment, automobiles, machinery, hardware, sports equipment, watch and clock industry, weapons and aerospace.

What is the process of CNC machining of aluminum alloy?

With the development of the times, industrial aluminum profiles generally refer to all aluminum profiles other than those for building doors and windows, curtain walls, indoor and outdoor decoration and building structures. Aluminum profile Machining process contains three full processes of melting, extrusion and coloring (coloring key contains: oxidation, electrophoresis process, fluorocarbon spraying, electrostatic powder coating, wood grain transfer, etc.). What are the aluminum profile Machining processes?

First, the dissolution of refining is the first process of aluminum profile Machining and manufacturing.

(1) Blending: According to the actual aluminum alloy model that must be produced and manufactured, the amount of various aluminum alloy components plus is measured, and various raw materials are effectively matched.

(2) Smelting: The selected raw materials are added to the melting furnace to melt according to the Machining technology, and the miscellaneous slag and vapor in the melting body are reasonably removed according to the de-gassing and slagging refining method.

(3) Forging: The smelted lithium bromide solution is cast into various specifications of round cast bars under certain forging process standards and refrigeration according to the software of deep water well forging system.

Second, extrusion is the second process of aluminum profile Machining.

Extrusion is the way of aluminum profile Machining and forming. First, according to the cross-sectional design plan of profile goods, production and manufacture of grinding tools, the use of extrusion machine will be heated good round casting bar from the grinding tool extrusion molding. The common model 6063 aluminum alloy, when extruded, also uses an air-cooled heat treatment whole process as well as after the artificial aging whole process to carry out the heat treatment process strengthening. Different models of heat treatable process to strengthen aluminum alloy, its heat treatment process regulations are not the same.

Third, coloring is the third process of aluminum profile Machining.

Anodic oxidation: Anodic oxidation is one of the important steps of aluminum profile Machining. The extruded aluminum alloy profile, whose surface corrosion resistance is not strong, shall carry out surface solution according to anodic oxidation to enhance the corrosion resistance, wear resistance and surface beauty and generosity of the aluminum profile.

(1) Aluminum alloy surface Machining. We usually use organic chemistry or physics to carry out cleaning on the surface of the profile to reveal the pure routine, in order to facilitate the obtaining of detailed and high-density human oxide film. Also able to get mirror glass or no light (matte) surface according to the mechanical equipment way.

(2) Aluminum combined with anodized polar oxidation. After the surface preparation treatment of the profile, under certain Machining process standards, the conventional surface produces anodic oxidation, transforming into a layer of high-density, porous structure, strong adsorption of AL203 film layer.

(3) Grouting reinforcement: the membrane pore porosity of the porous structure oxide film transformed into after anodic oxidation is closed, so that the oxide film pollution management, corrosion resistance and wear resistance is improved. The oxide film is completely transparent without color, and the strong adsorption force of the oxide film before using grouting reinforcement will absorb and accumulate some metal salts in the membrane pores, which can make the surface of the profile present many shades other than the original color (silver), such as: gray-black, copper, orange and stainless steel plate color, etc.

Industrial aluminum profiles are divided into base material, anodized profile, electrophoresis profile, powder coating profile, fluorocarbon paint coating profile, wear strip heat insulation profile, glue injection heat insulation profile, etc. The premise of the production of aluminum profiles is extruded material, round ingots are extruded to change the shape of the profile, in which molds and ingots are used, and molds also need to be designed, and after the design is done is the mold manufacturing, then is the test mold, if it is possible to directly into the warehouse, and finally to the mold heating.

Aluminum production and Machining process, aluminum ingots plus auxiliary materials melt casting, homogenization after the aluminum bar heating, and then put in the mold extrusion, extrusion out of the profile after heat treatment and start surface treatment and also material, need deep Machining on the hole tapping, do not need to directly pack into the warehouse can be.

What are the standards to be observed in the process of aluminum alloy Machining?

What are the standards to be observed in the process of aluminum alloy Machining? The three main characteristics of aluminum alloy Machining Aluminum alloy Machining services include cutting, punching, tapping and so on. If you can't follow the size to process accurately, it will cause the aluminum alloy not to be assembled up. So the standards of aluminum alloy machining are: no smooth surface without roughness, size cutting error within ±0.5mm, tapping and so on should be in line with the drawing size. Then what are the standards that need to be observed in the process of aluminum alloy Machining?

First, aluminum alloy Machining commodity quality control standards.

According to the accumulation of aluminum alloy Machining standards for so many years, the construction aluminum alloy profile fulfills the above specification, that is to say, as long as the aluminum alloy profile used in the construction industry, its goods must be produced and quality control of goods according to GB5237.1~5-2008 ﹑ GB5237.6-2004 mandatory specifications.

Second, aluminum alloy Machining kneading profile standard.

GB/T6892-2006 "commonly used industrial aluminum and aluminum alloy kneading profiles

Industrial aluminum alloy profiles refer to aluminum kneading profiles other than aluminum alloy for construction doors and windows, curtain walls and interior decoration, except for individual commodities to fulfill their special specifications, most of them fulfill the specification GB/T6892-2006 "commonly used industrial aluminum and aluminum alloy kneading profiles", which are mainly used in aerospace, transportation, track vehicles, electronic appliances, sports equipment, radiators, decoration, electric power Power, petrochemical industry, machinery manufacturing and other industrial fields.

Third, the standard of aluminum alloy Machining hot kneading profile.

This latest international standard of aluminum alloy decorative profiles GB/T26014-2010 "Aluminum alloy decorative profiles for non-construction

Non-construction aluminum alloy decorative profiles refer to the decorative aluminum alloy hot kneading profiles with the primary purpose of improving visual effects. The scale error of decorative profiles shall be indicated in the contract if there is special demand. If there is no special demand, it should conform to the rules of general grade in GB/T14846-2008 "Aluminum and Aluminum Alloy Kneading Profile Scale Error". The products are mainly used in the fields of vehicle decoration, home appliance parts, kitchen appliances, electronic appliances, interior decoration, medical equipment, instruments and meters, work equipment and so on.

Fourth, the standard of scale error of kneading profiles for aluminum alloy Machining.

This international standard of the latest kneading profile scale error GB/T14846-2008 "aluminum and aluminum alloy kneading profile scale error

Another specification for industrial aluminum alloy profiles fulfills GB/T14846-2008 "Aluminum and aluminum alloy kneading profile scale error". However, this specification is only for industrial aluminum alloy kneading scale, only the demand for scale can be produced according to this specification. Other needs are all according to GB/T6892-2006 specification.

In the nature, aluminum alloy and aluminum alloy profile are two different materials, and the meaning of aluminum alloy is more general. Its main components are divided into two categories: cast aluminum alloy Machining and deformed aluminum alloy Machining. For different grades, the control requirements of aluminum alloy composition are different.

Aluminum alloy parts Machining five common ways

1、Oxidation post-treatment of aluminum alloy Machining

Because of the strong corrosion resistance of aluminum alloy, it is easy to oxidize, so the surface treatment of aluminum alloy should be carried out to increase the wear resistance and corrosion of aluminum alloy and to meet the good-looking surface of aluminum alloy.

2、Squeezing and forming of aluminum alloy Machining

The required product model is carved out through the mold, and the semi-finished aluminum material is poured into the mold and extruded through the extruder to achieve the desired mold, and then CNC small batch Machining is carried out to meet the manufacturer's order requirements.

3、Casting and forming of aluminum alloy Machining.

Our Noble master will usually melt the good aluminum liquid through the casting technology for the first process of aluminum alloy Machining, casting out the required products.

4、Aluminum alloy Machining of melting out impurities.

Melting in the melting furnace to remove impurities in the process can ensure better performance of the product.

5、The ingredients of aluminum alloy Machining.

When we process the aluminum alloy, the reason why we need to carry out the ingredients is because aluminum itself is a relatively soft material, and we need to add some other things. Aluminum alloy is produced with greater hardness, and we need to configure out materials to match the aluminum to ensure the hardness of aluminum alloy.

Second, the aluminum alloy Machining process needs to pay attention to ten matters

We usually carry out aluminum alloy Machining need to pay attention to, the following is the master of NOB CNC Machining more than ten years of accumulated aluminum alloy Machining experience.

1、When we carry out aluminum alloy Machining, the operator should always order the machine, whether the situation of demoulding, if there is and the situation is not serious, consider stopping to see, and correct to continue aluminum alloy Machining.

2、After receiving the customer's order drawings and requirements, our Nopal aluminum alloy cnc Machining factory will carry out post-treatment such as oxidation and oil spraying on the appearance of aluminum alloy.

3、We also need to consider the wall thickness of aluminum alloy Machining, the thickness gap will be too big for filling.

4、In the structure, we try to avoid the appearance of the structure that leads to the complex structure of the mold, and we have to use more than one core extraction or spiral core extraction.

5、Take into account the mold problem when designing, if there are multiple positions of core extraction bit, try to put both sides, it is better not to put in the lower core extraction, so that the aluminum alloy die-casting lower core extraction will have problems after a long time.

6. At present, there are many unsafe factors in the manipulation system and electrical control system of many obsolete stamping equipment, which should be technically modified if they continue to be used. Stamping equipment manufacturers should improve the product design to ensure the safety and reliability of stamping equipment.

7. For CNC mass production, we can start from reforming aluminum alloy Machining technology and moulds to realize mechanization and automation. For example, we can adopt automatic, multi-station stamping machinery and equipment, adopt multiple planning tools and mechanized production devices, and adopt continuous die and compound die to merge CNC Machining process measures. All these not only can guarantee the safety of stamping operation, but also can greatly improve the production efficiency of aluminum alloy.

8、For us to use small batch CNC Machining, we must install safety guards in the stamping operation which is neither automated nor can use safety stamping tools to prevent the injury accidents caused by the operation errors. Various guards have their own characteristics and scope of use, and injuries can still occur if they are not used properly. Therefore, it is necessary to clarify the role of various protective devices so that they can be used correctly to ensure safe operation.

9、Because of the weak corrosion resistance of aluminum alloy, part of the CNC Machining factory has a humid environment and relatively strong corrosion, which is easy to short circuit and damage the internal components, so do a good job in the process of aluminum alloy Machining to prevent corrosion.

10、We should improve the product design and ensure the safety and reliability of the stamping equipment when using the stamping equipment manufacturer. When aluminum alloy Machining is carried out, once damage occurs, it can be replaced in time to avoid the emergence of defective products.

 Aluminum CNC machining, also known as computer gong machining or CNC machine tool machining, is mainly done from aluminum parts and cases. In recent years, with the rise of cell phones, computers, chargers, and auto parts, there is a demand for improved accuracy of aluminum parts Machining, but the other side has made a leap in the quality of aluminum CNC machining process to achieve high volume, high precision aluminum production. Next, Shenzhen Noble will introduce the advantages of CNC machining of aluminum alloy in detail for you. Aluminum alloy spare parts Machining

Finished and semi-finished aluminum alloy Machining in several ways.

Modern aluminum alloy Machining methods include semi-finished aluminum alloy Machining and finished aluminum alloy Machining. Then what are the several ways of aluminum alloy machining?

There are three kinds of finished aluminum alloy Machining.

1、The extrusion of aluminum alloy Machining. We use the extrusion method to make the mold, and the aluminum ingot is extruded through the mold by the compressor. We make good molds to process aluminum alloy in small quantities to meet the needs of customers.

2、Aluminum alloy Machining straightening. The straightness of aluminum alloy Machining needs to be straightened by a straightening instrument, which needs to reach the industry standard and meet daily needs.

3、Oxidation post-treatment of aluminum alloy Machining. After the aluminum alloy is tested and qualified, the aluminum alloy needs to be oxidized before it can be used, so that it is beautiful and resistant to corrosion and wear.

There are four kinds of finished aluminum alloy Machining

1、Cutting of aluminum alloy Machining. We usually use one normal aluminum profile of 6.02 meters, but in actual production and application, we need to combine various aluminum alloy length specifications together, so we need to cut as required to ensure the cutting length and accuracy of aluminum alloy.

2、Punching hole of aluminum alloy Machining. Industrial aluminum alloy installation is usually a combination of multiple aluminum profiles with different specifications and accessories, and the connections need to have pre-buried holes, and the holes here need to be operated by a professional punching machine according to the design requirements.

3、Tapping of aluminum alloy Machining. Industrial aluminum profiles, accessories, and connections are inevitably combined with bolts and nuts, screws, etc., which need to be tapped.

4、Milling slot of aluminum alloy Machining. In order to make the later assembly of other spare parts convenient, we usually need to mill grooves on the surface of aluminum alloy to ensure the assembly of other spare parts and save work efficiency.

Aluminum alloy Machining using CNC machine tool operation steps?

The working steps of CNC machine tools

  In the CNC machine tool Machining parts go through the following steps.

(1) Preparation stage

  According to the drawing of the machined parts, determine the relevant Machining data (tool track coordinate points, machining cutting amount, tool size information, etc.), according to the process plan, the choice of fixtures, tool types, etc. Select the relevant other auxiliary information.

(2) Programming stage

  According to the Machining process information, with the machine tool CNC system can recognize the language to write a CNC machining program (description of the Machining process), and fill out the program sheet.

(3) Prepare the information carrier

  According to the program, the list has been compiled, and the program is stored in the information carrier (perforated tape, tape, disk, etc.), through the information carrier will be all the Machining information to the CNC system. If the CNC Machining machine tools and computer networking, the information can be loaded directly into the CNC system.

(4) Machining stage

  When the implementation of the program is, the machine tool CNC system will process the program statement decoding, and computing, into the drive of the moving parts of the action instructions, in the unified coordination of the system to drive the timely movement of the moving parts, automatically complete the Machining of the workpiece Zhuzhou CNC machine tools.

  In general, the CNC machine tool is the information related to the Machining parts, with the prescribed text, numbers, and symbols composed of code, written in a certain format into a Machining program, the Machining program through the control medium into the CNC device, the CNC device after analysis and Machining, issued a variety of signals and instructions corresponding to the Machining program to control the machine tool for automatic Machining.

4. Stronger strength, advanced equipment, and excellent talent Machining a wider range of sizes and producing better prototypes.

The working principle of CNC machining of aluminum alloy What are the advantages of aluminum alloy machining?

First, the principle of aluminum alloy CNC machining:

The aluminum CNC machining principle is to use the automatic control system to install digital program process commands to control the automatic start and stop of CNC machine tool bearings. CNC inserts can be selected according to the CNC inserts, change the amount of tool eating and walking trajectory, to complete a lifetime of Machining required for a variety of auxiliary actions.

Second, aluminum alloy CNC machining advantages.

1. CNC machining of aluminum alloy can greatly reduce the total number of tooling, production, and Machining style of complex parts, one only need to change the Machining technology.

2. CNC machining of aluminum alloy is relatively stable and will not cause manual Machining deviation, resulting in different and even inferior products for each aluminum alloy.

3. Aluminum alloy CNC machining can produce complex aluminum parts, and even produce machined parts. It can also produce a variety of varieties, with high production efficiency, saving labor costs, while achieving diversified production.

Three, aluminum alloy CNC machining features.

1. Low hardness of the aluminum alloy

Compared with titanium alloy and hardened steel, aluminum alloy has a lower hardness, of course, heat-treatment or die-casting aluminum alloy also has a higher hardness. The general HRC hardness of aluminum plate is generally below HRC40 degrees. Therefore, in the case of machining aluminum alloys, the load on the tool is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed.

2. Low plasticity of aluminum alloy

Aluminum alloy has low plasticity and a low melting point. When machining aluminum alloy, the bonding edge problem is deep, the chip removal performance is poor, and the surface roughness is high. In fact, when machining aluminum alloy, it is mainly the knife and the roughness effect is not good. If the two problems of the fixed knife edge and the quality of the Machining surface are solved, the problem of machining aluminum alloy can be solved.

3. The tool is easy to wear

Because of the use of unsuitable tool material, in the case of machining aluminum alloy, there are more cases that the tool wears faster due to the problems of bar edge and chip discharge.

 What are the processes for Machining aluminum alloys?

Aluminum alloy can be obtained by adding other metals, such as silicon, iron, copper, and aluminum. It is characterized by low density, high strength, and high corrosion resistance. Its lightweight and high strength make aluminum alloy profiles widely used in the Machining and manufacturing of various parts. What are the Machining processes of aluminum alloy?

1、Aluminum alloy stamping Machining method.

Stamping is a molding method in which plates, strips, tubes, and profiles are deformed or separated by applying force to them using a press and die to obtain the desired shape and size. Stamping is a process in which parts of a product with a certain shape, size, and performance are processed by using the force of ordinary or specialized stamping equipment to subject the workpiece directly to the deformation force of a die. The three major elements of stamping are the metal plate, the die, and the equipment. Forming is a method of metal Machining that involves cold deformation, also known as cold stamping or sheet metal stamping. It is the main method of metal-plastic Machining.

2、Aluminum alloy precision casting Machining.

Precision casting is a special kind of casting. The parts obtained by this method generally do not need to be processed. Such as investment casting, die casting, etc. The general practice is: first design and manufactures a mold according to the product requirements (can be very small or no margin), use the casting method to cast wax to obtain the original wax mold; repeat the process of painting, sanding, hardening and drying the wax mold; dissolve and dewax the inner wax mold to obtain the mold cavity; bake the mold to make it sufficiently strong; pour the required metal materials, de-shell and clear the sand to obtain high-precision finished products; heat treatment, such as Heat treatment, such as heat treatment, cold working, etc. The heat treatment, such as heat treatment and cold Machining, is carried out according to the product requirements.

3、Powder Machining of aluminum profiles.

Powder manufacturing refers to the creation of metallic powder, which is made into materials or products through the process of mixing, molding, sintering, and other industrial processes. There are two points:

(1) The manufacture of metallic powder (including alloy powder), hereinafter referred to as "metallic powder".

(2) Metallic powder (sometimes a small amount of non-metal powder) can be made into various materials (so-called "powder metallurgical materials") or various materials (sometimes "powder metallurgical products") after mixing, forming, and sintering.

4、Aluminum alloy injection molding.

The organic binder is mixed with solid powder, granulated, heated with an injection molding machine in a plasticized state (~150℃), removed from the binder by chemical or thermal decomposition methods, sintered and compacted, and the finished product is obtained.

5. Aluminum alloy parts injection molding.

The solid powder is mixed with organic binder evenly, granulated, and injected into the mold cavity by injection molding machine in the plasticized state (~150℃) under heating, then the binder is removed from the molding blank by chemical or thermal decomposition method, and the product is obtained by sintering and densification. Compared with the traditional process, it has the characteristics of high precision, uniform organization, excellent performance, and low production cost. Its products are widely used in industrial fields such as electronic information engineering, biological medical devices, office equipment, automobiles, machinery, hardware, sports equipment, the watch and clock industry, weapons, and aerospace.
