  • Method for dressing a grinding wheel
    Patent number: 5325639
    Abstract: A method for dressing a grinding wheel by providing a slurry of liquid and solid particles wherein the particle size is smaller than grain size of the grinding wheel and the particles are free of sharp edges, and blasting the slurry at low pressure through a blasting nozzle onto a surface of the grinding wheel to remove foreign material on the grinding wheel by impact and by cleaning action of the blasted stream.
    Type: Grant
    Filed: March 2, 1993
    Date of Patent: July 5, 1994
    Assignee: Fuji Seiki Machine Works, Ltd.
    Inventors: Matao Kuboyama, Shigeharu Kobayashi, Fukuzo Yagishita
  • Dressing method and apparatus for super abrasive grinding wheel
    Patent number: 5168671
    Abstract: A method and apparatus for removing clogging material from between abrasive grains of a grinding wheel. A pressurized blasting fluid is supplied to a blasting gun, which in turn sucks an abrasive particle-liquid slurry into the gun. The slurry is entraining in the stream of blasting fluid, causing the liquid to be broken down into mist particles, and the resultant stream is discharged against the surface of the grinding wheel at a pressure in the range of 2.0 to 3.5 kg/cm.sup.2.
