[0002] A lathe is a machine that processes metal blanks into machine parts. There are many methods for processing mechanical parts in modern mechanical manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and fine surface roughness requirements, they generally need to be finally processed by cutting on a lathe.
