Precision parts processing process is generally the most common processing methods are turning and milling parts, that is, some of our common parts are precision parts or turning parts, can be collectively referred to as cutting parts, and cutting can be divided into "rough cutting" And "fine cutting", then the rough cutting and fine cutting what are the differences?
After the workpiece has been subjected to rough cutting, the entire workpiece has been very close to the workpiece itself requires the appearance and size, but this time the workpiece surface is still no small margin for fine cutting, fine cutting of the workpiece surface more Smooth, the size will be more accurate.
Normally, the workpiece is subjected to a rough cut and a fine cut to achieve the desired appearance and size of the workpiece. But not all of the workpiece as long as a cutting, some parts of the workpiece may need to do a number of rough cutting. But also some of the workpiece itself is not too high precision requirements or a small amount of cutting, and may only need to go through a fine cutting can meet the requirements of the workpiece.
Rough cutting because the workpiece needs to cut the margin, so it needs to have more cutting power than the fine cutting, which requires the machine, tool, the workpiece can meet the three, and rough cutting is likely to quickly remove the margin, and the effect After the surface performance can not be too rough.
Fine cutting is the surface of the workpiece performance, and dimensional accuracy to meet the workpiece requirements, so fine cutting tools need to use the tool is also very sharp, because the cutting amount is small, so the measurement precision is very high.
