摘要： A grinding wheel assembly for grinding and sizing workpieces such as an elastomeric power transmission belt is provided that comprises a wheel member including an abrasive, annular outer surface, a pair of annular flange members detachably connectable to opposing sides of the wheel member for providing opposing annular flanges that circumscribe and radially extend beyond opposing sides of the outer surface of the wheel member, wherein each of the flanges includes an inner abrasive surface for sizing a workpiece which is substantially coarser than the abrasive surface on the outer surface of the wheel member. Additionally, an undercut portion is provided beneath the distal end of each of the inner side surfaces of the flange members for providing a space for collecting grindings produced by the sizing operation, as well as for creating a flow of turbulent air which effectively expels the grindings from the assembly, thereby preventing them from accumulating and compacting between the inner sides of the flanges of the grinding wheel assembly and the belt or other workpiece.
