We know that the machining of parts is inseparable from the tool. But have you ever thought about which tools are inseparable? Feeding does not turn on the stepper motor.custom cnc parts, If the stepper motor fails during the machining of precision parts, the tool will not be able to cut. Abnormal stepper motor during parts processing Generally, after starting the precision parts processing program, the stepper motor may vibrate or not rotate, indicating that the control system of the stepper motor is abnormal. Either there is a problem with the stepper motor itself, or there is a problem with the drive circuit.
If there is no problem with the circuit, then there must be a problem with the control system of the stepper motor. The control part is abnormal, which generally appears on the high-power triode and its protection element release diode on the motor drive board. These two originals are the most easily damaged. If it can be reactivated, it should be possible to get the stepper motor spinning again, or just replace it. Stepper motor loses step during tool operation If the drive voltage is reduced, the torque of the stepper motor will decrease, resulting in loss of step. This is mainly a power problem, check the drive power. When the high-voltage switch fails and the high-voltage power supply cannot be introduced, the output torque of the stepper motor is significantly reduced when running at high speed, and it is inevitable to lose steps. In addition to the switch, failures in other places can also cause lost steps. The lead screw, lead screw, slider, stepper motor reducer, etc. should also be checked. If there are bends, chips or deformations in these places, it will also increase the running resistance and cause the stepper motor to lose step.
