What is the difference between the transformation of machine tools with PLC and the transformation of CNC machine tools

PLC transformation of traditional relay-contactor electrical control features:

The past use of the electrical control system, are the use of relay control logic, relay electrical control system wiring is complex, fault diagnosis and troubleshooting difficulties, there are also the following problems:

1, the contactor contacts can easily be burned by the arc and thus lead to poor contact and sometimes cause short-circuit damage to the equipment;

2, the control function of the relay is fixed in the electrical circuit, the function is very fixed, single, poor flexibility.

PLC transformation advantages:

1, versatility, adaptability;

2, perfect diagnostic capabilities, easy maintenance;

3, high reliability, flexibility;

4, anti-interference ability;

5, programming is simple;

6, cost-effective and other advantages in machine tools and other production equipment. equipment in the electrical control circuit modification plays an extremely important role.
