Wire cutting machine guide wheel life - the life of the guide wheel is not calculated according to time, depends on what kind of material you process, as well as the quality of cutting fluid, better than bad can be judged by inspection .
Tightly tighten the wire, raise the height to more than 300, turn on the machine, and check the jitter degree of the molybdenum wire before and after. If the jitter is too large, it means that there is a problem with the front and rear guide pulleys or bearings. It needs to be removed for inspection. If it cannot be used, it needs to be replaced.
If the jitter is not too large and it is indirect, you can continue to machine parts that do not require high accuracy.
The
Check the cut off the workpiece, if the surface of the workpiece under the correct pulse width between the processing of a clear silk mark or precision error, it also means that the need to replace the guide wheel and the bearing.
Guide wheel replacement should not be beaten the bearing, the force can not be too large, have an impact on the bearing life of the guide wheel.
Usually, always tighten the wire, and the looseness of the wire will also affect the life of the guide wheel.
There is also the most important point: the use of the original guide wheel spare parts and special water-based hydraulic fluid cutting BMW Ma line, the overall maintenance of the machine tool has a certain degree of help.
