1, the first external internal

The reliability of modern numerical control system is higher and higher, the failure rate of the numerical control system is lower, and most of the faults are caused by the non system itself. As the numerical control machine tool is a set of mechanical, hydraulic, electrical as one of the machine tool, the occurrence of its failure will be reflected by the three To. Repair personnel should be from outer to inner one by one investigation. To avoid arbitrarily unsealed, remove, otherwise it will expand the fault, so that the loss of precision machine tools, reduce performance. System external fault is mainly due to the detection switch, hydraulic components, pneumatic components, electrical actuators, mechanical devices, etc.

Arising from problems.

2, the first mechanical electrical

In general, mechanical failure is easy to detect, but the numerical control system and electrical fault diagnosis is difficult. Before troubleshooting, we should pay attention to the removal of mechanical failure. CNC winding machine

3, the first static dynamic

First, the static state of the machine tool power, through understanding, observation, testing, analysis, confirmed that the power will not cause failure after the expansion of the accident, can give the machine power. In the running state, the dynamic observation, inspection and testing are performed to find the fault. The occurrence of destructive fault will be energized, you must first rule out the danger, keeps power.

4, simple and complex

When there are many kinds of faults are intertwined, at a time when not start, should first solve the problem of easy, after the difficulty of solving the problem. Often simple problem solving, the difficulty of the problem may also become easy.
