  • Support fixture for thermal curing processes
    Patent number: 6814565
    Abstract: A flexible or semi-rigid support fixture is sized and shaped to supportably engage a surface of a polymeric matrix object such as an organic bonded abrasive grinding wheel. The support fixture is utilized to support the object to help prevent slumping and/or expansion during thermal curing operations. The fixture is fabricated from a material, such as silicone rubber, that is capable of withstanding heat commonly associated with thermal curing operations and which provides sufficient resilience to permit use with objects manufactured within a relatively wide range of dimensional tolerances. Suitable materials include silicone rubber or other polymers or copolymers such as PTFE, FEP, Polyimide or blends with or without fillers or substrates.
    Type: Grant

  • Grinding wheel
    Patent number: 4913708
    Abstract: The grinding performance of organic bonded abrasive bodies whose abrasive portion is wholly or partially composed of aluminous abrasive grits is significantly improved by providing a magnesium oxide-rich or manganese oxide-rich coating on furfural-wetted grits just prior to addition of resin and filler in the mixing process.
