Host machine, which is the theme of CNC machine tools, includes machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical part used to complete various cutting processes.
Numerical control device is the core of numerical control machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software. It is used to input digital part programs, complete the storage of input information, data transformation, interpolation operation and realize various control functions.
The driving device is the driving part of the actuator of the CNC machine tool, including the spindle drive unit, feed unit, spindle motor and feed motor. Under the control of numerical control device, he realizes the spindle and feed drive through electrical or electro-hydraulic servo system. When several feeds are linked, the machining of positioning, straight line, plane curve and space curve can be completed.
Auxiliary devices, some necessary supporting parts of index control machine tools, are 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 worktables, numerical control turntables and numerical control dividing heads, as well as cutting tools and monitoring and detection 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 manufacturing industry, especially in automotive, aerospace, and military industries. CNC technology has developed rapidly in both hardware and software.
