  • Abrasive article for high-speed grinding operations
    Patent number: 9539701
    Abstract: An abrasive article includes a bonded abrasive body having abrasive particles comprising microcrystalline alumina (MCA) contained within a bond material. In an embodiment, the bonded abrasive body has a strength ratio (MOR/MOE) of at least about 0.80. Additionally, the bonded abrasive body may have a MOR of at least 40 MPa for a MOE or at least about 40 GPa and the bonded abrasive body may be capable of grinding a workpiece that includes metal at a speed of at least about 60 m/s at a material removal rate of at least about 0.4 in3/min/in (258 mm3/min/mm).

  • 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.

  • Abrasive article for ultra high material removal rate grinding operations
    Patent number: 8945253
    Abstract: An abrasive article including a bonded abrasive body having a bond material present in an amount of not greater than about 15 vol % for the total volume of the body, abrasive particulate material contained in the bond material, the abrasive particulate material including abrasive agglomerates and unagglomerated abrasive particles, wherein the body comprises an abrasive particulate ratio (APp:APagg) within a range between 3:1 and about 1:3, wherein APp represents the amount (vol %) of unagglomerated abrasive particles present in the body and APagg represents the amount (vol %) of abrasive agglomerates present in the body, and a porosity of at least about 42 vol % of the total volume of the bonded abrasive body.
