When the grinding wheel is worn and fails to meet the edge grinding requirements, an experienced craftsman is required to manually adjust the compensation for the wear of the grinding head according to the edge grinding effect. However, the compensation effect is often not satisfactory, and a lot of time is spent on manually adjusting the compensation amount, resulting in a lot of labor costs. Therefore, it is necessary to design an automatic compensation system for the polishing grinding head. Summary of the invention
