Fault diagnosis method of CNC lathe

Fault diagnosis method of CNC lathe

In case of failure of precision CNC lathe, it should be stopped immediately, diagnosed and eliminated in time, otherwise it will lead to greater damage or even danger. The principle of fault diagnosis of precision CNC lathe should be mastered.

  1. Outside before inside

The reliability of modern precision CNC lathe system is higher and higher, the failure rate of CNC system itself is lower and lower, and most of the failures are caused by non system reasons. Because the precise numerical control lathe is a machine tool with mechanical, hydraulic and electrical integration, the occurrence of its fault will also be reflected by the three. Maintenance personnel should check from outside to inside one by one. Try to avoid unsealing and disassembling at will, otherwise it will enlarge the fault and make the machine lose precision and performance. The external faults of the system are mainly caused by the problems of detection switch, hydraulic components, pneumatic components, electrical actuators and mechanical devices.

  1. First static then dynamic

First, in the static state of power failure of the precision CNC lathe, through understanding, observation, testing and analysis, it is confirmed that the failure will not expand after power on, and after the accident occurs, the machine tool can be powered on. In the running state, dynamic observation, inspection and testing are carried out to find the fault. However, if there is a destructive failure after power on, the danger must be eliminated before power on.

  1. Mechanical before electrical

Generally speaking, mechanical fault is easy to find, but the diagnosis of numerical control system and electrical fault is more difficult. Before the troubleshooting of precision CNC lathe, we should first pay attention to the elimination of mechanical faults.

  1. Simple before complex

When there are many kinds of faults intertwined, we should solve the easy problems first, and then solve the more difficult problems. After solving simple problems, difficult problems may become easier.
