  • Method and apparatus for fabricating abrasive tools
    Patent number: 6609964
    Abstract: Methods for orienting fibers and an apparatus for orienting fibers are provided for the fabrication of improved thin abrasive wheels utilizing uniform non-woven fiber reinforcement discs. The wheels are more resistant to hub push-out failure during grinding than wheels reinforced with woven fiber cloth.
    Type: Grant
    Filed: September 27, 2000
    Date of Patent: August 26, 2003
    Assignee: Saint-Gobain Abrasives Technology Company

  • Abrasive tool for grinding needles
    Patent number: 6015338
    Abstract: Abrasive tools and a grinding process are for use in the manufacture of hypodermic needles. In particular, a formulation including selected bond components, and a process for manufacturing grinding wheels having an embrittled bond permits a new method for grinding of fine hollow metal tubes to shape the tips of hypodermic needles with the substantial elimination of metal burrs or fines from the grinding process.
