Machine tool refers to the machine that manufactures the machine, also known as the working machine or machine tool, which is conventionally referred to as the machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: In addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but all parts that require high precision and surface roughness are generally required. The final machining is done by cutting on the machine tool. Machine tools play a major role in the modernization of the national economy.
