ABSTRACT:
An abrasive wheel is partially defined by a support member and by a plurality of abrasive flaps on such member. A hole is disposed centrally in the support member to receive a mandrel for rotating the wheel. The support member has at its radial periphery an annular surface with a constant radius at progressive positions in the annular direction. The flaps are fixedly supported (as by epoxy) on the annular surface in a partially overlapping relationship between successive pairs of flaps. Each of the flaps has abrasive particles on one of its surfaces. Each of the flaps is disposed on the annular surface of the support member with the abrasive particles facing outwardly from such support surface. Each of the flaps defines an acute angle with the annular surface and extends at its opposite axial ends beyond the axial positions of support by such support surface. However, the flaps are fixedly positioned relative to one another even at the axial positions beyond the opposite axial ends of the annular surface on the support member as a result of the support by the support member and the overlapping relationship between the flaps in the successive pairs. In this way, the abrasive wheel is able to provide a positive and forceful action on a workpiece surface along the full axial width of the flaps when the abrasive wheel is rotated against the workpiece surface.
