The spindle rotation accuracy of a high-efficiency precision CNC grinding machine is tested by using the spindle rotation accuracy tester produced by Lion Precision Company. The results show that the spindle rotation accuracy of the grinding wheel spindle system is very high. The results of the research on rotation accuracy

static rigidity

vibration resistance and thermal stability of the grinding wheel spindle show that it is a grinding wheel spindle with excellent performance. This will improve the grinding performance of CNC grinding machines.
