The structure of CNC machine

  • December 28,2017.

CNC machine is a high precision and high efficiency automated machine,It is a machining method which controls the displacement of component and cutter with the numeric information. There are various of materials available for machining: 316, 304 stainless steel, carbon steel, alloy steel, aluminum alloy, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, POM, UHWM and other raw materials, It can be make complex structure of square and circular combination parts. It is an effective solution for multi variety production, small batch production, complex shape, high precision, high efficiency automatic machining.

The structure of CNC machine

Main engine, It is mail part of CNC machine, including machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical part which used to complete various cutting machining.

Numerical control device, It is the core of CNC machine, including hardware (PCB, CRT display, key box, tape reader etc.) and the corresponding software, It is use for input digital of parts program, and completed the storage of input information, data transformation, interpolation and achieve various control functions.

Driving device, It is the driving part of the CNC machine actuator, including the spindle drive unit, feed unit, spindle motor and feed motor etc. It can realize the spindle and feed driving by electrical or electro-hydraulic servo system under the control of the numerical control device. When several feed linkage, It can finish the machining of positioning, straight line, plane curve and space curve.

Auxiliary device, There are some necessary matching parts of CNC machine, It can ensure the operation of CNC machine, such as cooling, chip removal device, lubrication, lighting, monitoring and etc. It includes hydraulic and pneumatic device, chip removal device, exchange platform, CNC turntable and CNC indexing head, and also includes tools and monitoring detection devices.

Programming and other accessory devicethat can be used to program and store parts outside the machine.
