Title: Dressing tool for the surface of an abrasive cloth and its production process

Abstract: Onto the surface of a dressing tool for removing the clogging of an abrasive cloth, diamond grains of plural groups each having a different average particle diameter are subjected to be mixed and then fixed. In this state, the upper end of small diamond grains 4 is projected over nickel plating 2. Thereby foreign substances aggregated in the concave of the abrasive cloth are effectively removed and at the same time wearing the surface of the nickel plating 2 is prevented.
