How to improve the finish of stainless steel parts?

There are many influencing factors to improve the finish of stainless steel parts during the processing of stainless steel parts, including lathes, materials and tools. General machine tools can reach Ra1.6, precision high-speed machine tools for aluminum can reach Ra0.2. The finish of patterned parts must be reduced.


The main thing here is that the part wrinkles are difficult to handle, and there are many factors. If you are a long axis type, it may be that the tailstock jacking force is not enough, or the tailstock is moving. If there is no problem with the tailstock, tool wear, including processing parameters, Cutting fluid and other problems. There is also the material for stainless steel parts processing, and the corresponding selection tool. Furthermore, it includes the problem of the machine tool itself, which can only be solved by groping in practice. There is no way to solve it alone, and other reasons need to be explored.


In fact, the main reason is because of the processing strength of stainless steel parts. It may be that the length of the processed part is too long, or your tool is too long. The center of the tool is high. Choose the right tool. Some are caused by the resonance of the machine tool and the part tool.

 

How to improve the finish of stainless steel parts?


First you have to make sure that the stability of the lathe is whether the lathe is fixed. Then whether the spindle will shake when running at high speed, the second is that the coolant is very important, and then your tool must be sharpened, and the chip flute must be opened, to prevent the workpiece from being scratched due to poor chipping and the turning of the tool The corners are made into rounded corners, and the other is not to resist the knife when installing the knife. The last is to match the speed of the spindle and the speed of the feed. If your lathe is not working well, it is recommended to buy some sandpaper, and it is recommended to deal with the working direction of the turning tool when the sandpaper is made. Look better.
