Common faults of CNC machine tool holders and their diagnosis and repair?
Tool holder cannot be started
1 The pre-tightening force of the tool holder is too large. When the end of the worm is rotated by the wrench, it is not easy to rotate, but it can be rotated when the force is applied, but the tool post cannot be started after the next clamping. This phenomenon occurs, and it can be determined that the reason why the tool holder cannot be started is that the pre-tightening force is too large, and the clamping current can be eliminated by adjusting the motor of the small tool holder.
2 The internal mechanical block of the knife holder is stuck. When the worm is rotated from the end of the worm, the clockwise direction does not move, which is caused by mechanical jamming. Firstly, check whether the clamping device is against the positioning pin against the ratchet groove. If it is, then the ratchet and the screw coupling pin hole should be rotated at an angle to re-punch the connection; secondly, check whether the spindle nut is locked, such as The nut is locked and should be readjusted;
Again, due to poor lubrication, the rotating parts are ground and killed. At this time, it should be disassembled, observe the actual situation, and be lubricated.
