In the machining industry, generally the most common processing methods are turning and milling parts, so when choosing, many people will choose the one that suits them because of these two, but here is a reminder that when we are choosing It must be distinguished between the two, what are the advantages of the two, and which one is more suitable for you. Let's take a look at 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. The workpiece is processed by fine cutting. Its surface is smoother and its dimensions are more accurate.
Under normal circumstances, the workpiece can achieve the required appearance and size of the workpiece after one rough cutting and one fine cutting. However, not all workpieces only need to be cut once, and some parts of some workpieces may need to be rough cut multiple times. At the same time, there are some workpieces whose accuracy requirements are not too high or the cutting amount is small, and it is possible to achieve the requirements of the workpiece with only one fine cutting.
Rough cutting because the workpiece requires a large cutting margin, so it needs to have a greater cutting force than fine cutting. This requires the machine, tool, and workpiece to meet the requirements, and it is possible to quickly remove the margin in rough cutting. Moreover, the surface properties after the effect should not be too rough.
Fine cutting is to meet the requirements of the workpiece surface performance and dimensional accuracy. Therefore, the tools required for fine cutting also need to be very sharp, because the cutting volume is small, so the measurement precision is very high. Today we will stop here first.
