Maintenance of abnormal machining accuracy of NC machine tools
Production often encountered CNC machine tool processing accuracy of abnormal faults. This kind of fault concealment is strong, the diagnosis is difficult.
causeThere are five main reasons for this kind of failure: (1) the unit of machine tool feed has been changed or changed. (2) the OFFSET (NULL) anomaly of each axis of machine tool. (3) the axial reverse gap (BACKLASH) is abnormal. (4) abnormal operation of the motor, that is, electrical and control part of the fault. (5) mechanical failure, such as wire rod, bearing, shaft coupling and so on. In addition, the processing program, the selection of tools and human factors may also lead to abnormal machining accuracy.
