Abstract (en)
[origin: EP0770457A1] A number of pyramidal or truncated-pyramidal projections (50) are formed on a portion of a metal base (1) forming a grinding face, to be homogeneously distributed at substantially uniform heights. Super abrasive grains (8) having grain sizes which are smaller than the heights of the projections are fixed to the surfaces of the projections (50). A coating film (10) consisting of fluororesin is formed to at least partially cover the outer surface of the grinding face (2) including the surfaces of the super abrasive grains (8), for preventing deposition of a workpiece. Since the outer surface of the grinding face (2) is covered with the coating film (10), sharpness of this grinding wheel is improved and clearances between the super abrasive grains are hardly clogged up with chips, while the chips are hardly deposited onto the grinding face. <IMAGE>
