How to diagnose the abnormality of CNC machining parts?
CNC machining centers mainly process some precision parts,but the accuracy of CNC machining parts is often abnormal,and it is difficult for CNC lathe masters to directly determine where the problem is.The reason for the abnormal processing accuracy is often concealed,the diagnosis is difficult,and the troubleshooting is difficult.The Jiexiang CNC machining center gives a brief introduction to the diagnosis method.
1.Intuitive method:(Wang Wen asked)Ask-the machine tool's fault phenomenon,processing status,etc.;see-CRT alarm information,alarm indicator,capacitor and other components deformation smoke and burn,protector trip,etc.;listen-abnormal movement;-Electrical components burnt and other odors;touch-oscillation,heat,poor contact,etc.
2.Parameter viewing method:The parameters are usually stored in RAM.Sometimes the battery voltage is insufficient.If the system is not energized or externally interfered for a long time,the parameters will be lost or disordered.The relevant parameters should be viewed and corrected according to the fault characteristics.
3.Isolation method:Some problems are difficult to distinguish between the numerical control part and the servo system or mechanical part.The isolation method is often used.
4.The same type of adjustment method replaces the template that is suspected of being faulty with the same standby board,or exchanges the same template or unit.
5.The utility program test method writes some small programs for the G,M,S,T,and the full instructions of the function.When these problems are diagnosed when the diagnosis is diagnosed,the missing function can be discriminated.
The above is the diagnosis method of the abnormality of CNC machining parts summarized by Jiexiang CNC machining center.The accuracy abnormality will not only cause unnecessary loss,but also greatly affect the processing of subsequent work and increase the time cost.Therefore,it is necessary to diagnose and deal with the problem of abnormality.
