James M. McHale has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Silver-coated abrasives, tools containing silver-coated abrasives, and applications of these tools
    Patent number: 6666753
    Abstract: Flute grinding cemented carbide workpieces with a diamond containing resin bond grinding wheel is improved by restricting the diamond to comprise a silver-coated diamond; conducting the grinding in the presence of a lubricant consisting of only straight oil; and conducting the grinding at a wheel speed of less than about 30 m/s and preferably about 20 m/s. The preferred diamond is coated with about 25% and 75% silver by weight.
    Type: Grant
    Filed: February 2, 2001
    Date of Patent: December 23, 2003
    Assignee: General Electric Company
    Inventors: James M. McHale, Jr., James H. Dailey, Markus Jacobuss, Daniel R. Riehle, Juergen Von Dungen
  • Surface modification of coated abrasives to enhance their adhesion in resin bond tools
    Publication number: 20030005646
    Abstract: The retention of metal-coated superabrasive particles in a resin bond matrix is improved by incorporating a silane coupling agent into a mixture of metal-coated superabrasive particles and resin bond matrix. The silane can incorporated by providing a metal-coated superabrasive particle treated with a silane coupling agent for adding to the resin bond matrix. Alternatively, the silane can reacted into the resin bond matrix and then the metal-coated superabrasive particles added. Both diamond and cubic boron nitride are useful in the invention.
