The host, which is the theme of CNC machine tools, includes mechanical components such as the machine body, columns, spindle, and feed mechanism. He is a mechanical component used to complete various cutting processes.

Numerical control device is the core of numerical control machine tools, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, used to input digital part programs, store input information, transform data, perform interpolation operations, and implement various control functions.

The driving device is the driving component of the CNC machine tool actuator, including the spindle driving unit, feed unit, spindle motor, and feed motor. He drives the spindle and feed through an electrical or electro-hydraulic servo system under the control of a numerical control device. When several feed rates are linked, the machining of positioning, straight lines, planar curves, and spatial curves can be completed.

Auxiliary devices, some necessary supporting components of index controlled machine tools, used to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange workbenches, CNC turntables, and CNC indexing heads, as well as cutting tools and monitoring and detection devices.

Programming and other auxiliary equipment can be used for programming, storage, etc. of parts outside the machine.

Since the Massachusetts Institute of Technology developed a CNC machine tool in 1952, it has been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries. CNC technology has developed rapidly in both hardware and software aspects
