  • Rotary drill bit and method for making same
    Patent number: 4186628
    Abstract: A rotary rock drill bit comprising a plurality of cutting elements or cutters mounted in the crown of the drill bit. Each cutting element comprises a thin planar layer of polycrystalline diamond bonded in the crown of the bit at a rake angle of between -10.degree. and -25.degree.. In another embodiment each cutting element comprises an elongated pin mounted at one end in the drill crown and thin layer of polycrystalline diamond bonded to the free end of the pin so as to be disposed at a rake angle of between -10.degree. and -25.degree..
    Type: Grant
    Filed: March 20, 1978
    Date of Patent: February 5, 1980

  • Grinding wheel dresser
    Patent number: 4098253
    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.

  • Grinding wheel dressing method
    Patent number: 4027648
    Abstract: A cubic boron nitride, diamond or similar grinding wheel is dressed by applying a dressing slurry comprising a multiplicity of inorganic crystals dispersed in a normally fluid carrier medium against the rotating wheel to form a layer of dressing slurry on the surface of the wheel and then pinching the slurry between the wheel and a metal piece until dressing is substantially complete.

  • Method for improving surface finish of workpieces ground with abrasive wheels
    Patent number: 3990192
    Abstract: The surface finishes of workpieces ground with cubic boron nitride, diamond or similar grinding wheels is improved by applying a lapping composition comprising a multiplicity of fine grit abrasive particles dispersed in a normally solid but friction-meltable organic polymeric matrix against the rotating wheel, during spark out, and causing the lapping composition to melt and form a layer on the surface of the wheel and applying the lapping layer against the workpiece until the desired surface finish is achieved.
