Composite grinding pellets of 200 weight part is mixed in master batch of 100 weight part punched out to preliminarily form a disk, from which an annular grinding body is shaped. Said master batch of 100 weight part, clay of 200 weight part, white carbon of 40 weight part and phenol resin of 30 weight part are mixed and shaped into a sheet. Said sheet is punched into three types of large-size, medium-size and small-size sheets, which are used as the basic elements for a supporting board. A sheet of reinforcing embedded metal net is punched, flashed, immersed in phenol resin solution, and finally dried. Such prepared basic elements are inserted in a molding metal and heat- pressed. Since the grinding body 1 and the supporting element 2 are made of the same material, the joining faces thereof are unified.
