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

CNC machine tools have effectively solved complex, precise, small batch, and multi variety parts processing problems. They are a flexible and efficient automated machine tool, representing the development direction of modern machine tool control technology and a typical electromechanical machine tool
