[0002] A metal cutting machine tool is a machine tool that processes various metal workpieces by cutting, grinding or special processing methods to obtain the required geometric shape, dimensional accuracy and surface quality. It plays a crucial role in the field of mechanical manufacturing and is widely used in many industrial fields such as automobiles, aerospace, and mold manufacturing.

[0003] During the working process of a metal cutting machine tool, feeding is a key link. A high-quality feeding mechanism can ensure that the material is accurately and quickly delivered to the cutting position, thereby improving the processing efficiency and quality of the machine tool.
