The productivity relationship of grinding wheels

Mainly related to surface roughness and productivity during machining. When rough grinding, the grinding allowance is large and the required surface roughness value is large. Coarse abrasive particles should be selected. Because the abrasive grains are coarse and the pores are large, the grinding depth can be larger, and the grinding wheel is not easy to block and heat up. When precision grinding, the allowance is small and a lower roughness value is required. Fine abrasive particles can be selected. Generally speaking, the finer the abrasive particles, the better the surface roughness during grinding.
