How to deal with the power failure of CNC vertical lathe?

The maintenance technology of NC vertical lathe is not only the premise to ensure normal operation, but also plays a great role in promoting the development and improvement of NC technology. Therefore, it has become a special discipline. Let's talk about how to deal with the NC vertical lathe after power failure.

When the CNC vertical lathe is just put into use, it is necessary to return to the reference point when the system is restarted after power failure. That is, after moving each axis outside the non-interference area manually, make each axis return to the reference point. Otherwise, a crash may occur. Therefore, after processing every day, move the axis of the machine tool to the position. At this time, it is not necessary to return after operation or power failure again.

Faults caused by external hardware operation are common faults in NC repair. Generally, it is caused by problems in detection switch, hydraulic system, pneumatic system, electrical actuator and mechanical device. For some of these faults, the cause of the fault can be found through the alarm information. For general CNC systems, there is fault diagnosis function or information alarm. The maintenance personnel of NC vertical lathe can use these information means to narrow the scope of diagnosis. Although some faults have alarm information display, it can not reflect the real cause of the fault. At this time, it is necessary to analyze and solve according to the alarm information and fault phenomenon.

For the repair of CNC vertical lathe, it is important to find problems. Especially the external faults of NC machine tools. Sometimes the diagnosis process is complex, but once the problem is found, it is relatively simple to solve. The following two principles shall be followed for external fault diagnosis. Master the working principle and action sequence of the machine tool. Secondly, be able to use PLC ladder diagram. The status display function of NC system or external programmer monitors the operation status of PLC. Machine tool technology is developing, and NC machine tool maintenance technology is also following up. If artificial intelligence develops well in the future, I hope the maintenance will be more convenient and simple.
