Tips: Spindle Motor Bearing Maintenance
We should check the quality of the bearings from time to time during the use of the spindle motor. Under what circumstances do the bearings of the spindle motor have to be replaced?
1. The high noise of the spindle motor may be because the bearing is broken. The bearing is the core component of the high-speed rotation of the spindle motor. The bearing has abnormal noise, which is the lack of oil in the bearing raceway. If the sound is a little loud, you can still use it. But at this time the spindle motor is working, you should pay attention to increase the circulating water volume to improve the cooling effect, try not to run for a long time, work for a period of time, you should stop to cool down.
2. If the spindle motor vibrates, do not continue to use it. On the one hand, it affects the machining accuracy. On the other hand, the motor vibrates, which indicates that the balls of the bearing have been severely worn, and it is easy to wear the bearing seat. Moreover, if you continue to use the motor at this time, it will easily cause the bearing to heat up, and the temperature will easily cause the bearing to stop operating and even burn the coil. In the case of the vibration of the spindle motor, it must be used with caution.
