  • Bonded abrasive article and method of grinding
    Patent number: 10377016
    Abstract: An abrasive article comprising: a first body comprising a first bond material having abrasive particles contained within the first bond material, wherein the first body comprising the first bond material comprises a ratio of VAG(1)/VBM(1) of at least about 1.3; a second body comprising a second bond material having abrasive particles contained within the second bond material, wherein the second body comprising the second bond material comprises a ratio of VAG(2)/VBM(2) of less than about 1.3, and wherein VAG is a volume percent of abrasive particles within a total volume of the first or second body respectively and VBM is a volume percent of the first or second bond material within the total volume of the first or second body respectively.

  • Abrasive Tool and a Method for Finishing Complex Shapes in Workpieces
    Publication number: 20150079883
    Abstract: An abrasive tool includes a bonded abrasive body having abrasive grains contained within a bonding material, wherein the bonded abrasive body comprises a complex shape having a form depth (FD) of at least about 0.3. The form depth is described by the equation [(R1?Rs)/R1], wherein Rs is a smallest radius (Rs) at a point along the longitudinal axis of the bonded abrasive body and R1 is a largest radius (R1) at a point along the longitudinal axis of the bonded abrasive body. The abrasive tool can be used to finish complex shapes in workpieces.
