Description of the Related Art A donut-shaped glass plate used for an optical disk, a magnetic disk, etc. is processed by an inner diameter grindstone and an outer diameter grindstone which are annularly arranged. That is, when processing a doughnut-shaped glass plate, each rectangular glass plate is vacuum-sucked to the processing table one by one, and the inner diameter grindstone and the outer diameter grindstone that are annularly arranged are rotated to form a rectangular shape. Pull out the donut-shaped glass plate from the glass plate. As a result, a donut-shaped glass plate is processed.

Since a larger radius than the inner diameter grinding wheel 10, when the outer径砥stone 12 and the inner diameter grinding wheel 10 Ru is rotated at the same angular velocity, the peripheral speed of the outer径砥stone 12 as shown in FIG. 4 (V 1) is an inner diameter of the grinding wheel 10 It becomes faster than the peripheral speed (V 2 ). Therefore, the wear amount of the outer diameter grindstone 12 becomes larger than the wear amount of the inner diameter grindstone 10. As a result, when the outer diameter grindstone 12 cannot be used, the outer diameter grindstone 12 and the inner diameter grindstone 12 can be used even if the inner diameter grindstone 10 is still usable.
Since the stone 10 is replaced together, the inner diameter grindstone 10 is wasted. That is, the conventional inner / outer diameter grinding wheel has a problem that the outer diameter grinding wheel 12 and the inner diameter grinding wheel 10 cannot have the same life.
