CNC lathe is a machine developed in modern times, it is composed of information carrier, CNC equipment, servo system and machine body. CNC lathes compared to general lathes, its processing power has been significantly improved, and some previously difficult to process or can not process the workpiece can also be processed, can say that CNC lathes to our daily life has brought a lot of benefits.

CNC equipment is the core of CNC lathes, that is, often said NC(general CNC equipment) or CNC(computer numerical control equipment), NC is a way of the early development of CNC lathes, most of the CNC lathes now use CNC system. The function of CNC equipment is to accept the processing information input into the equipment, after decoding processing and operation, announce the corresponding command pulse to the servo system to complete the parts processing.

The servo system is the performance part of the CNC lathe, which is composed of motor and transmission equipment. The servo system is subjected to the command pulse signal from the CNC equipment to control the displacement and speed of the machine tool performance parts (workbench or tool holder).

When machining on the CNC lathe, according to the part drawing program, the code and instruction pattern of the program are mostly in line with the ISO specification and the corresponding national specifications, and then the program is input into the NC or CNC through the information carrier, and the CNC system announces the instruction according to the program content, on the one hand, the motor in the servo system controls the movement of the machine tool through the transmission equipment. On the other hand, the other auxiliary movements of the machine tool are controlled, such as the spindle speed, the steering selection, the opening and stopping of the cooling pump, etc., and the two aspects work together to complete the processing content.

CNC lathes since the 1950s came out, so far a few years. Because in single-piece production and small-batch production, the use of drill cnc machine to process complex shaped parts not only improves labor productivity and processing quality, but also shortens the production preparation cycle and reduces the requirements for workers' technical proficiency. Therefore, it has become an important development direction to realize technological innovation and technological revolution in single-piece and small-batch production. Countries around the world are also vigorously developing this new technology.
