The composition of CNC machine tools

CNC machine tools are generally composed of the following parts:

● Main unit

He is the subject of CNC machine tools, including mechanical components such as machine bodies, columns, spindles, feed mechanisms, etc. It is a mechanical component used to complete various machining operations.

● CNC device

It is the core of CNC machine tools, including hardware (printed circuit boards, CRT monitors, key boxes, paper tape readers, etc.) and corresponding software, which is used to input digital part programs, and complete the storage of input information, data transformation, interpolation operations and the realization of various control functions.

● Drive device

It is the driving component of the actuator of CNC machine tools, including spindle drive unit, feed unit, spindle motor and feed motor. He implements spindle and feed drive under the control of CNC units via electrical or electro-hydraulic servo systems. When several feeds are linked, the processing of positioning, straight line, plane curve and space curve can be completed.

●Auxiliary devices

Some necessary supporting components of the index control machine tool are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip evacuation devices, exchange tables, CNC rotary tables and CNC indexing heads, as well as tools and monitoring and detection devices.

●Programming and other ancillary equipment

It can be used to program and store parts outside the machine. Since the Massachusetts Institute of Technology 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, and CNC technology has developed rapidly in both hardware and software.
