Abstract
A grinding body for on-line roll grinding has a grindstone of a cup shape. The grindstone is on a surface portion, and near a peripheral edge, of a circular support base plate, so that a peripheral edge portion of the circular support base plate has on a surface side thereof a two-layer structure. This two-layered structure includes a flat ring-shaped portion jutting toward an inner periphery so as to define a groove opening inward. The grindstone is mounted on the flat ring-shaped portion; and a damping material is filled and mounted into the groove. This grinding body can effectively prevent the formation of a spiral mark and a pitching surface mark, improve the grinding power and grinding accuracy, and prolong the life of the grindstone.
