CNC cutting is an important part of cutting machine, it is composed of computer system, servo system, control unit and actuator.
(1) the computer system is composed of a computer host, a display and a keyboard.
(2) the servo system is the closed-loop control of the motor under the control of the computer to achieve stepless speed regulation of the motor.Because the steel plate cutting site conditions are poor, cutting speed is not high, so the servo system mostly USES ac servo system.Ac servo system has strong anti-interference ability, especially at low speed.
(3) the control unit is the switch between computer and manual control, which is the center of logic processing of manual control and computer control signals, namely the center of sending out control signals, so as to realize the control of computer, each motor and each electromagnetic valve.
(4) the actuator includes each motor and each electromagnetic air valve, etc.
