Abstract
A cubic boron nitride, diamond or similar grinding wheel is dressed by applying a dresser comprising a multiplicity of abrasive particles dispersed in a normally rigid but friction-meltable organic polymeric matrix against the rotating wheel and causing the dresser to melt and form a dressing slurry on the surface of the wheel and then pinching the slurry between the wheel and a workpiece until dressing is substantially complete.
Claims9
A method for dressing a bonded rigid, grinding wheel comprising the steps of (i) setting the wheel against a workpiece at substantially zero clearance, (ii) rotating the wheel and applying a wheel dresser comprising a multiplicity of abrasive crystals dispersed in a normally solid friction-meltable organic polymeric matrix to the moving surface of said grinding wheel whereby the matrix is melted and the crystals and melted polymer are spread on the surface of the wheel, and (iii) abrading said wheel surface having said crystals spread thereon against said workpiece to remove selected portions of the surface of said wheel, said steps (i) and (ii) being carried out in any order, sequentially or simultaneously.
