ABSTRACT:
Glass bonded grinding wheels including graphite or other inert dry film lubricant filler can be made by conventional techniques if the filler material is protected from oxidation by a metal cladding. Diamond or cubic boron nitride wheels are particularly described and high grinding ratios are achieved. Low porosity can be achieved because of the wettability of the metal cladding by the glass during firing.
