CNC means computer numerical control.
1, CNC machine tools
(1), metal cutting
Hole machining, tapping, boring, milling, turning, thread cutting, plane cutting, contour machining, plane grinding, cylindrical grinding, internal grinding, etc.
2. Electrode wire cutting machine.
(3), punch, punching, stamping, metal forming, bending and other machine tools.
(4) industrial robots.
5], injection molding machine.
[6], detection, measuring machine.
Once, woodworking machinery.
(8) Special material processing machinery: such as processing stone, glass and radioactive minerals.
Levies, special processing machinery
Laser processing machine, gas cutting machine, welding machine, plotter, printing machine, etc.
With the development of electronic technology, computer technology and IT technology, at present, these machine tools and processing equipment can be controlled by numerical computers with numerical data, which is called numerical control.
2. Numerical control system
CNC system means computer numerical control system.
Machine tool numerical control is a comprehensive control technology which integrates many disciplines.
A CNC system includes: (1) CNC control unit (digital controller part). (2) Servo drive unit and feed servo motor. (3), spindle drive unit and spindle motor. (4) PMC(PLC) controller. 5] Control signal input/output (I/O) unit of high-voltage cabinet of machine tool (including tool magazine). [6], the position measurement and feedback unit of machine tools (usually included in the servo drive unit). Once, external shaft (mechanical) control unit. Such as: tool magazine drive shaft, exchange workbench, loading and unloading manipulator, etc. Information input/output equipment. Such as computers, disk drives, memory cards, keyboards, special information equipment, etc. Levies, network. Such as Ethernet, HSSB (high speed data transmission port), RS-232C port, etc. And the local area network of the processing location. from
