  • Abrasive Articles with Novel Structures and Methods for Grinding
    Publication number: 20080066387
    Abstract: Bonded abrasive tools, having novel porous structures that are permeable to fluid flow, comprise a relatively low volume percentage of abrasive grain and bond, and a relatively low hardness grade, but are characterized by excellent mechanical strength and grinding performance. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.
    Type: Application
    Filed: September 27, 2007
    Publication date: March 20, 2008
    Applicants: Saint-Gobain Abrasives, Inc., Saint-Gobain Abrasifs Technologie et Services, S.A.S.
    Inventors: Anne Bonner, Eric Bright, Edward Lambert, Dean Matsumoto, Xavier Orlhac, David Sheldon

  • Abrasive tools for grinding electronic components
    Patent number: 6394888
    Abstract: Abrasive tools containing high concentrations of hollow filler materials in a resin bond are suitable for polishing and backgrinding of hard materials, such as ceramic wafers and components requiring a controlled amount of surface defects. These highly porous abrasive tools comprise fine grit abrasive grain, such as diamond abrasive, along with the hollow filler material and resin bond.
