If the system parameters of the CNC H beam drilling machine changes or changes of electrical parameters, mechanical failure, machine not optimizedmotor abnormalities, machine tool position ring abnormality or control logic is wrong, is a common cause of machining accuracy of NC machine tool in the production of abnormal fault, find out the relevant fault point and processing,machine tool can recover to normal.
Often met in production of CNC machining abnormal fault. The fault diagnosis ofconcealment, difficulty. The cause of such failures are mainly in the followingaspects:
1, the system parameter changes or modifications.
2. The machining accuracy resulting in , abnormal mechanical fault.
3, machine electrical parameters are not optimized motor abnormalities.
4, machine tool position ring abnormality or control logic.
In addition, compiling, tool machining program selection and artificial factors, may also lead to abnormal processing precision. Below we according to this reason toexplain CNC H beam drilling machine if there is failure to how to troubleshootmaintenance.
CNC H beam drilling machine generates a fault, need host check: check themechanical connection strong, is loose and damage situation, pay special attention to the coupling, ball screw and other active clearance is appropriate,should be timely tightening and adjustment. Check all lubricating points whetheroil and grease filling provisions. The motor has no abnormal sound, abnormal vibration, the sliding surface lubrication. In addition, the coolant unit inspection also need to check the CNC H beam drilling machine: the coolant amount is appropriate, whether the product has a chip, the pump is working properly.
