The most common processing methods in the process of precision parts processing are turning and milling parts, that is, some of our common precision parts are milling parts or turning parts, which can be collectively referred to as cutting parts, and cutting can be divided into "rough cutting" What is the difference between rough cutting and fine cutting?
After the rough cutting of the workpiece, the entire workpiece is actually very close to the appearance and size required by the workpiece itself, but at this time there is still a large margin on the surface of the workpiece for fine cutting, and the surface of the workpiece after fine cutting is more Cleaner and more accurate in size.
Usually, the workpiece can achieve the required appearance and size of the workpiece after one rough cutting and one fine cutting. However, not all workpieces need only one cut, and some parts of some workpieces may require multiple rough cuts. At the same time, there are also some workpieces whose precision requirements are not too high or the cutting amount is small, and it is possible to meet the requirements of the workpiece after only one fine cutting.
Rough cutting requires a larger cutting force than fine cutting because the workpiece needs to have a large cutting allowance. This requires the machine, tool, and workpiece to be able to match, and rough cutting can remove the allowance quickly, and the effect is The final surface performance should not be too rough.
Fine cutting is to meet the requirements of the surface performance and dimensional accuracy of the workpiece. Therefore, the tools required for fine cutting also need to be very sharp. Because the cutting amount is small, the measurement precision is very high.
