Abstract
A grinding wheel center hole protection pad is provided, which mainly include a positioning portion attached to the peripheral thereof and the guiding portions disposed at the center hole at the axial center thereof. The guiding portions serve as the isolation layer between the center hole of the grinding wheel and the peripheral plate guiding wall of a flange plate. Therefore, the grinding wheel can be closely attached to the flange plate during the assembling process to decrease eccentricity. Accordingly, it is not necessary to perform the cutting calibration process and balance adjustment by a cutting machine, which can reduce the waste of manpower and material resources.
