Abstract:
    An abrasive wheel comprised of abrasive granules dispersed throughout and adhered in a matrix with a binder system which comprises a blend of a tough adherent binder and a smear-reducing quantity of a smear-reducing compatible polymer. An abrasive wheel having abrasive granules adhered by the binder without the compatible polymer has a tendency to smear onto the surface of a workpiece when rotated thereagainst under heat-generating conditions such as high wheel to workpiece pressure and surface speed.
