Abstract
A bonded abrasive tool comprises a blend of abrasive grains and a bond component. The blend of abrasive grains comprises a filamentary sol-gel alumina abrasive grain and agglomerated abrasive grain granules. A bonded abrasive tool comprising an agglomerate of filamentary sol-gel alumina abrasive and non-filamentary abrasive grains, and a bond component is also disclosed. The filamentary sol-gel alumina abrasive grain has a length-to-cross-sectional-width aspect ratio of greater than 1.0. The agglomerated abrasive grain granules comprise a plurality of abrasive grains held in a three-dimensional shape by a binding material. A method of making such a bonded abrasive tool as described above is also disclosed.
