The CNC Lathe will inevitably encounter some small problems in processing and production. If the operator can understand the correct method of CNC lathe fault diagnosis in advance, he can quickly find the cause of the fault and solve it on the spot. Then we sorted out the correct methods and processes for fault diagnosis of standard CNC lathes for operators to learn!

1. from the outside to the inside

CNC lathe processing is a machine tool integrating mechanical, hydraulic, and electrical, so the occurrence of faults must be comprehensively reflected from the three. Therefore, the maintenance personnel is required to master the principle of "external first and internal second", that is, when the CNC machine tool breaks down, the maintenance personnel should use the methods of looking, smelling, listening, asking, etc. to check one by one from the outside to the inside.

Faults caused by external hardware operation are common faults in NC repair. Generally, it is caused by problems in the detection switch, hydraulic system, pneumatic system, electrical actuator, and mechanical device. Some of these faults can be found through the alarm information. For general CNC system, it has a fault diagnosis function or information alarm.

Maintenance personnel can use this information means to narrow the diagnosis scope. Although some faults have alarm information display, they can not reflect the real cause of the fault. At this time, it is necessary to analyze and solve the problem according to the alarm information and fault phenomenon.

2. mechanical before electrical

CNC lathe machining is a piece of advanced machining equipment with high automation and complex technology. The mechanical fault is easy to find, but system fault diagnosis is more difficult.

3. static before dynamic

The maintenance personnel should be quiet before moving, and should not blindly start. They should first ask the operator about the process and status of the fault, and then check the instructions and data to find out the cause of the fault, and then eliminate the fault.

4. public before private

The commonality problem affects the whole, while the specificity problem only affects the local.

5. simple before complex

When a variety of faults are intertwined and covered up, and there is no way to start at the moment, the easy problems should be solved first, and then the larger problems should be solved. NC machine tool processing is often in the process of solving simple faults, and difficult problems may also become easier. Clear your mind and make the difficult ones easier.

6. general before special

When troubleshooting a fault, first consider the most common possible causes, and then analyze the special causes that rarely occur.

When the CNC lathe breaks down, we treat it calmly. According to the above inspection methods, we can generally solve the problem! If you can't find the cause, you can contact the manufacturer for after-sales consultation. Don't evaluate the fault casually to avoid misjudgment!
