  • Grinding wheel with combination of fused and sintered abrasive grits
    Patent number: 4741743
    Abstract: A combination of fused alumina grits with sintered gel alumina abrasive grits is shown to be more effective than either abrasive alone in cutting steel bars with bonded abrasive wheels at intermediate cutting speeds.
    Type: Grant
    Filed: August 19, 1985
    Date of Patent: May 3, 1988
    Assignee: Norton Company

  • Phenolic resin bonded grinding wheels
    Patent number: 4682988
    Abstract: A grinding wheel is described which is bonded with a phenol formaldehyde resin based bond containing hexamethylenetetramine as the curing agent. The wheels are made by first wetting the abrasive with furfural in varying quantities relative to the amount of hexamethylenetetramine in the phenol formaldehyde resin. Different amounts of the curing agent require different specific amounts of furfural to produce optimum properties in the finished grinding wheel.
    Type: Grant
    Filed: October 25, 1983
    Date of Patent: July 28, 1987
    Assignee: Norton Company
    Inventors: Kesh S. Narayanan, Gordon E. Hickory
  • Grinding aid
    Patent number: 4609381
    Abstract: This invention relates to organically bonded abrasive articles that include grinding aids. It has been determined that when known grinding aids such as alkali metal sulphates and alkali metal chlorides are cofused in about eutectic proportions and added to thermoset resin bonded abrasive articles in the form of finely crushed particles having an approximate eutectic composition that an improved abrasive article results.
    Type: Grant
    Filed: December 13, 1984
    Date of Patent: September 2, 1986
    Assignee: Norton Company
    Inventors: Kesh S. Narayanan, Suresh S. Vagarali
  • Resin bonded abrasive bodies for snagging metal containing low abrasive and high filler content
    Patent number: 4253850
    Abstract: Organic bonded abrasive bodies such as snagging wheels and wheel segments for conditioning billets, slabs, and castings have abrading portions with 0 to 8% pores by volume, a low abrasive content of from 24 to 45% by volume of 4 to 36 grit size abrasive, substantially constant volume of a thermosetting resin of from 18 to 24% by volume and a high content of filler material constituting from 29% to 56% by volume of the body and wherein at least 80% by volume of the filler material is inorganic material.
    Type: Grant
    Filed: August 17, 1979
