  Maintenance knowledge of electrical control system of inclined bed CNC lathe.brass machining machini(图1)

  In addition to the CNC equipment (servo system for spindle drive and feed drive), the electrical control system of the inclined bed CNC lathe also includes a strong electrical control system for the machine tool. The power control system of the machine tool is mainly composed of the drive of the general communication motor and the logic control equipment PLC and operation panel of the machine tool electrical appliances. Today, I will introduce the maintenance and maintenance knowledge of the general relay contactor control system and PLC programmable controller in the strong electrical control system of the downward inclined bed CNC lathe:

  1. Maintenance and maintenance of general relay contactor control system

  In addition to the CNC system, there is also a general relay contactor control system for economical CNC machine tools. Its maintenance and maintenance work is mainly how to adopt measures to prevent the strong electromagnetic interference of the contactors and relays in the strong electric cabinet. Electromagnetic components such as contactors and relays in the power cabinet of CNC machine tools are all sources of disturbance in the CNC system. Due to the communication contactor, when the communication motor starts and stops frequently, its electromagnetic induction phenomenon will cause noise such as spikes or surges in the control circuit of the CNC system to disturb the normal operation of the system. Therefore, measures must be taken to eliminate these electromagnetic disturbances. For example, with regard to the communication contactor coil, an RC network is connected in parallel at its two ends or the three-phase input end of the communication motor to suppress the disturbing noise generated by these electrical appliances. In addition, pay attention to prevent oxidation of contactors and relay contacts and poor contact of the contacts.

  2. Maintenance and maintenance of PLC programmable controller

  The PLC programmable controller is also an important electrical control part of the inclined bed CNC lathe. In addition to the control of the auxiliary motion and auxiliary motion of the machine tool, the powerful electric control system also includes the control of maintenance switches, various strokes and limit switches. In the above process, the PLC programmable controller can replace most of the machine tool electrical appliances in the strong electric control system on the machine tool, and then complete the logical control of the spindle, tool change, lubrication, cooling, hydraulic, pneumatic and other systems. When the PLC programmable controller and the numerical control equipment are integrated, they form a built-in PLC, and when they are located outside the numerical control equipment, they form a stand-alone PLC. Because the structure of PLC is similar to the numerical control equipment, its maintenance and maintenance can refer to the maintenance and maintenance of numerical control equipment.
