The principle of fault diagnosis of precision nc lathe

Fault diagnosis is a very important stage to eliminate the fault of nc lathe.The following principles should be followed in fault diagnosis.

First, the failure rate of the external and internal modern CNC machine tools themselves has become lower and lower, most of the failures are caused by reasons other than the system itself.Repair personnel should be removed from the outside to the inside one by one, as far as possible optional opening, demolition, otherwise it will expand the fault, the machine tool precision loss, to avoid reducing the performance of jinhua precision CNC lathe supply.

The first host after the electrical fault is generally easier to find the host, but also easier to find, but, repair personnel should be from the outside to the inside one by one, as far as possible open, disassembly, otherwise it will expand the fault, so that the accuracy of the machine tool lost, performance reduction.

The main machine after the electrical generally easier to find the main machine fault;Numerical control system and electrical fault diagnosis is difficult.From practical experience, CNC machine failure is caused by a large part of the host part of the fault.Therefore, in the fault point inspection before, the first should pay attention to eliminate mechanical failure, so often can achieve a successful double the effect of yuyao precision CNC lathe supply.

First static after dynamic lathe in the static state of power failure, through understanding, observation, testing, analysis;Confirm that there will be no fault expansion or accident after electrification, can be electrified to the lathe.Perform dynamic observation, inspection and test to find faults in the running state.But after electrification may produce destructive fault, want to eliminate danger above all hind, ability is electrified.

In the first place, multiple faults should be interwoven after simplicity, first solving the easy problems, and then solving the more difficult problems.After the simple problem is solved, the more difficult problem may also become easy to supply cixi precision CNC lathe.

The most common possible causes must be considered before the common and special faults are eliminated, and then the special causes that seldom occur must be analyzed.
