A straight type cast-iron bond diamond-grinding wheel was used. A cup-shaped grinding wheel was used for a truing grinding wheel so that the grinding wheel section has an R-shape, and the inner periphery part of the cup-shaped grinding wheel was brought into contact with the grinding wheel for machining. The cup-shaped grinding wheel having an inner diameter of 46 mm was used.
