Principle of fault diagnosis for precision CNC lathe
Principle of fault diagnosis for precision CNC lathe

If the precision CNC lathe fails, it should be stopped immediately, and diagnosed and eliminated in time. Otherwise, it will cause more damage and even danger. The principle of fault diagnosis for precision CNC lathes should be mastered.

1, first external and internal

The reliability of modern precision CNC lathe systems is getting higher and higher, the failure rate of CNC system itself is getting lower and lower, and most of the failures are caused by non-system itself. Since the precision CNC lathe is a machine tool integrating mechanical, hydraulic and electrical, the occurrence of faults will be reflected by the three. Maintenance personnel should first conduct an investigation from the outside to the inside. Try to avoid unpacking and disassembly at will, otherwise it will expand the fault and make the machine lose precision and reduce performance. Faults outside the system are mainly caused by problems with the detection switches, hydraulic components, pneumatic components, electrical actuators, mechanical devices, and the like.

2, first static after dynamic

First, in the static state of the power-off of the precision CNC lathe, by understanding, observing, testing, and analyzing, it is confirmed that the power will not be caused to expand after the power is turned on, and the machine can be energized after an accident occurs. In the running state, perform dynamic observation, inspection and testing to find faults. If a destructive fault occurs after power-on, the danger must be removed before powering up.

3, first mechanical and electrical

In general, mechanical faults are easier to detect, and the diagnosis of CNC systems and electrical faults is more difficult. Before troubleshooting a precision CNC lathe, first take care to eliminate mechanical failures.

4, first simple and complicated

When there are multiple faults intertwined, when there is no way to start, you should solve the easy problem first, and then solve the difficult problem. Often, after a simple problem is solved, a difficult problem may become easier.
