Main functions of CNC lathe electrical system

2020/5/5 17:29:17 Viewers:

Programmable logic controller is the logic control center of machine tools. In the future, all kinds of activities and efficiency instructions from CNC will be logically sequenced, so that they can operate safely and accurately, coordinately and orderly; all kinds of information and work information not from machine tool will be transmitted to CNC, so that CNC can quickly and accurately send out further control instructions, so as to complete the control of all machine tools.

The electrical hardware circuit of CNC lathe follows the function of PLC constantly. The main mission of electrical hardware circuit is the generation and control circuit of power supply, the part of barrier relay and all kinds of promotion appliances (relays and Contactors). There are few relay logic circuits.

CNC lathe (electrical part) includes all electric ideas, solenoid valves, brakes, various switches, etc. They are promoters of various behaviors of machine tools and reporters of various essential situations of machine tools. The possible main obstacles here are the breakage of electrical appliances and the disconnection or cracking of connecting wires and cables.

The spindle drive system of CNC lathe receives the drive instruction from CNC, and drives the main electric idea to rotate through the speed and torque (power) Regulation and transmission drive information, and receives the speed feedback together to promote the speed closed-loop control. At the beginning and the end, PLC announced that CNC was used to control the functions of the spindle.

The feed servo system receives the speed command from CNC for each active coordinate axis, drives the servo motor to rotate through the speed and current (torque) Regulation and transmission drive information, completes the machine coordinate axis activity, and receives the speed feedback information together to promote the speed closed-loop control.
