How to improve the finish of stainless steel machining parts

When performing CNC machining of stainless steel parts, many factors affect the smoothness of stainless steel parts. Among them, materials, cutting tools, and lathes will all have an impact. General machine tools can reach Ra1.6, and precision high-speed machine tools for aluminum alloy machining can reach Ra0.2. The machining finish of stainless steel parts with patterns should be discounted.

1. The main reasons for the machining finish of stainless steel parts:

The main reason is the machining strength of stainless steel parts. It may be that the protruding length of your CNC machining parts is too long, the length of your tool is too long, and the center of the tool is high. Choose a suitable tool. In some cases, if the rotational speed is too high, the resonance of the machine tool and the part tool will also cause the pattern to appear.

The main thing here is that the wrinkle of the part is difficult to deal with, and there are many factors. If you are a long-axis type, it may be that the tailstock is not strong enough, or the tailstock is moving. If there is no problem with the tailstock, the tool wear, including machining parameters, Cutting fluid, and many other issues. There is also the material for machining stainless steel parts, and the corresponding selection of tools. Furthermore, it includes the problems of the machine tool itself, which can only be solved by groping in practice

2. How to improve the finish of stainless steel CNC machining parts:

First of all, you have to make sure that the stability of the lathe is good or not, that is, whether the lathe is fixed well. Then there will be vibration when the spindle is running at high speed, the second is that the coolant is very important, your tool must be ground well, and the chip flute must be opened to prevent the workpiece from being scratched due to poor chip removal, and the turning tool from falling over. When the corner is made into a circular arc corner, the other is not to resist the knife when installing the knife. The last thing is to match the speed of the spindle and the speed of the tool. If your lathe is not working well, it is recommended to buy some sandpaper for it. When sanding it, it is recommended to process it according to the working direction of the turning tool, so that the texture of the stainless steel parts can be processed. Look better.
