numerical control machine tool is the abbreviation of Computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into numerical control devices through information carriers. After calculation and processing, the CNC device sends out various control signals to control the action of the machine tool, and automatically processes the parts according to the shape and size required by the drawing.

CNC machine tool better solve the complex, precision, small batch, multi-variety parts processing problems, is a flexible, high-efficiency automatic machine tool, represents the development direction of modern machine tool control technology, is a typical mechatronics products.
