1、 CNC machine tool and CNC system
CNC means computer numerical control.
- CNC machine tools
(1) for metal cutting
Hole processing, tapping, boring, milling, turning, thread cutting, cutting plane, contour processing, surface grinding, cylindrical grinding, internal grinding, etc.
(2) wire electrode cutting machine.
(3) punch, step punch, stamping, metal forming, bending and other machine tools.
(4) industrial robots.
(5) injection molding machine.
(6) testing and measuring machine.
(7) woodworking machinery.
(8) special material processing machinery: such as processing stone, glass, radioactive mineral, etc.
(9) special processing machinery
Laser processing machine, gas cutting machine, welding machine, drawing machine, 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 computer with numerical data, which is called CNC control. Is a metal processing machine tool – vertical machining center of the general structure.
- CNC system
CNC system means computer numerical control system. It is the basic configuration diagram of a CNC system. CNC control of machine tool is a kind of integrated control technology, which is a typical CNC control system.
A CNC system includes:
(1) CNC control unit (numerical controller part).
(2) servo drive unit and feed servo motor.
(3) spindle drive unit and spindle motor.
(4) PMC (PLC) controller.
(5) input / output (I / O) list of control signal of machine tool strong current cabinet (including tool magazine)
Yuan.
(6) position measurement and feedback unit of machine tool (usually included in servo drive unit).
(7) external shaft (Mechanical) control unit. Such as: tool magazine, exchange table, upper
Drive shaft of cutting manipulator, etc.
(8) information input / output equipment. Such as computer, disk drive, memory card, keyboard, special information equipment, etc.
(9) network. Such as Ethernet, hssb (high speed data transmission port), RS-232C port and local area network of processing site. I / olinki servo amplifier and motor are used to drive and control external machinery. The hardware of CNC unit (controller part) is actually a special microcomputer. It is the core of machine tool control designed and produced by CNC equipment manufacturer.
