1, check the bearing

Bearing is an important part of the air cooling spindle. If there is a problem with the bearing, the spindle cannot run normally. Therefore, a comprehensive inspection should be carried out on the bearing before starting the machine and using it. First of all, it is necessary to see whether the bearing is in a state of oil shortage. If it is short of oil, it is necessary to replenish lubricating oil in time. Secondly, it is necessary to see whether the bearing wiring meets the relevant requirements and whether the grounding measures are done.

2. Check the fastening screws

Because the spindle rotates at high speed during operation, if the screw used for fixing is loose, it will fall off during operation and lead to failure. Therefore, before starting the air cooling spindle, check whether the fastening screws are tightened, and also need to check the screws and pins of the coupling to see whether they are tightened, and also need to check whether the belt joint is good and other aspects of the problem.

3, check the power supply voltage

If the power supply voltage is not stable, it will have a great impact on the electrical parts of the spindle, and even burn the motor. So in order to ensure the safe operation of no abnormalities, inexpensive and high-quality air cooled spindle before starting the spindle power supply and voltage detection. If the power supply voltage can not meet the requirements of use, then it is necessary to take timely measures to avoid serious impact on the spindle.
