Stainless steel precision parts processing process to improve the finish of the parts, there are many factors affecting the lathe, materials, tools have an impact. General machine tools can reach Ra1.6, processing aluminum precision high-speed machine tools can reach Ra0.2.
The main thing here is that the parts fold is difficult to deal with, there are more factors, if you are a long shaft class, perhaps the tailstock top 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 aspects of the problem.
There is also the material of stainless steel precision parts processing, corresponding to the choice of tools. In addition, including the machine tool itself, this only in practice to find out to solve the problem. Alone, there is no way to solve the problem, but also need to explore other reasons.
In fact, the main reason is because of the problem of stainless steel precision parts processing strength, it is possible that the length of your processing parts probed too long, or the length of your tool is too long. The center of the tool is high. Choose the right tool. There is too high a rotation speed caused by the resonance of the machine tool and the part tool will also appear pattern.
To first ensure the stability of the lathe is good is the lathe fixed situation is good. Then is the spindle will not jitter when running at high speed, followed by coolant is very important then is your tool to grind well, as well as chip groove to open well, to prevent poor chip out of the workpiece scratch, as well as the turning tool chamfering made of rounded corners, in addition is to install the tool when not to resist the knife.
Is to match the spindle speed and the speed of the tool, if your lathe work is not very good, it is recommended to buy some sandpaper to get, in the sandpaper to get the time recommended according to the direction of the work of the turning tool processing, so that the stainless steel precision parts processing out of the grain better look some.
