Precision parts processing process is generally the most common processing method is the turning process and milling parts, that is, some of our common precision parts are milling parts or turning parts, can be collectively referred to as cutting parts, and cutting can be divided into "rough cutting" and "fine cutting". So what is the difference between rough cutting and fine cutting?
After rough cutting, the workpiece is actually very close to the appearance and size of the workpiece itself, but at this time there is still a small margin on the surface of the workpiece for fine cutting, the surface of the workpiece after fine cutting treatment is more polished, the size will also be more accurate.
Usually, the workpiece can achieve the required appearance and size after one rough cut and one finish cut. However, not all workpieces require only one cut, and some parts of the workpiece may require multiple rough cuts. At the same time, there are some workpieces that do not require too much precision or have a small cutting volume, and they may only need to go through one finishing cut to achieve the requirements of the workpiece.
Rough cutting because the workpiece needs to cut a large margin, so it needs to have a greater cutting force than fine cutting, which requires the machine, tool, workpiece can meet the three, and rough cutting is fast to remove the margin, and the effect of the surface properties can not be too rough.
Fine cutting is the surface performance of the workpiece, and dimensional accuracy to meet the requirements of the workpiece, so fine cutting requires the use of tools also need to be very sharp, because the cutting volume is small, so the measurement of precision requirements are very high.
