Why do balanced grinding discs vibrate during installation
Analyze the cause of the malfunction: the connection sleeve end jumps too much, the stopper does not fit well with the front plate, and the grinding disc installation shaft jumps too much.

Solution: Suggest to the customer

1. The end jump of the connecting sleeve should be controlled within 2 threads

2. The coaxiality between the connecting sleeve stopper and the process shaft is within 2 wires

3. The diameter jump at the connection between the process axis and the workpiece is within 3 threads

4. Ensure the tolerance of the stopper and suggest H7/h6 for coordination with the universal joint front plate

5. The shaft diameter of the grinding disc installation machine should jump within 3 threads to ensure that the balance is consistent with the actual working conditions.
