CNC machine tools were invented by American inventor John Parsons in the last century. With the development of electronic information technology, the world machine tool industry has entered the era of mechatronics with digital manufacturing technology as the core, among which CNC machine tools are one of the representative products. CNC machine tools are an important basis for the processing of the manufacturing machine and the national economy. It provides equipment and means for all sectors of the national economy, with an infinitely magnified economic and social effect. The industrialized countries such as Europe, America and Japan have completed the industrialization of CNC machine tools, and China has been in the development stage since its inception in the 1980s.
