A self-bonded foamed abrasive article and a method of machining using such an article. The machining method includes providing a workpiece having a worksurface and removing material from the worksurface by moving an abrasive relative to the worksurface, wherein the abrasive comprises a foamed abrasive body consisting of abrasive grains and a porosity of at least about 66 vol %.

Self-bonded foamed abrasive articles and machining with such articles

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.

Abrasive tools having a permeable structure

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.
