Comprehensive analysis:
A total of 100 units were tested. The first 7 units were tested to the limit. The maximum load of the machine was set at 25%.
After the sharpening, the load of the machine tool can be reduced, the grinding force of the grinding wheel can be maintained, and the outer diameter of the grinding wheel does not change much. In conclusion, the hardness of the grinding wheel is hard, the grinding wheel is easy to block holes, and the grinding wheel maintainability is good.
