  • Method for making microabrasive tools
    Patent number: 7015268
    Abstract: A microabrasive tool is formed from a slurry including liquid, abrasive grains, a bonding material, and a polymer—for example, gellan gum. The slurry is cast in a mold, and the polymer is ionically cross-linked. Cross-linking the polymer fixes the structure of the bonding material and the abrasive grains, wherein the abrasive grains are dispersed substantially uniformly within the bonding material. The ionically cross-linked structure of bonding material and abrasive grains can then be fired to form a microabrasive tool.
    Type: Grant
    Filed: January 16, 2002
    Date of Patent: March 21, 2006
    Assignee: Saint-Gobain Abrasives Technology Company
    Inventors: Kenneth E. Manwiller, Anne B. Hardy
