● Main machine, it is the main body of CNC machine tools, including machine parts, columns, spindles, feed mechanisms and other mechanical parts. He is a mechanical part used to complete various cutting processes.

● NC device is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, used to input digital part programs, and complete storage and data of input information Transformation, interpolation and various control functions.

● Drive device, it is the drive part of the NC machine tool actuator, including the spindle drive unit, feed unit, spindle motor and feed motor, etc. He realizes the spindle and feed drive through electric or electro-hydraulic servo system under the control of numerical control device. When several feeds are linked, processing of positioning, straight line, plane curve and space curve can be completed.

● Auxiliary devices, necessary supporting components of index-controlled machine tools, 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 tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and inspection devices.

● Programming and other auxiliary equipment can be used to program and store parts outside the machine.

Since MIT developed the world's first CNC machine tool in 1952, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries. CNC technology is used in both hardware and software Has developed rapidly
