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 1Ø 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.
Cette invention concerne un outil abrasif aggloméré comprenant un mélange de grains abrasifs et un agent liant. Ledit mélange contient un grain abrasif d~alumine en sol-gel filamenteux et des granules de grain abrasif agglomérées. Cette invention concerne également un outil abrasif aggloméré comprenant un agglomérat de grains abrasifs d~alumine en sol-gel filamenteux et de grains abrasifs non filamenteux, et un agent liant. Le grain abrasif d~alumine en sol-gel filamenteux possède un rapport de forme longueur-largeur de la section transversale supérieur à 1,0. Les granules de grain abrasif agglomérées contiennent une pluralité de grains abrasifs maintenus en forme tridimensionnelle par un matériau liant. Cette invention concerne également un procédé de fabrication d~un tel outil abrasif aggloméré.
