Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An abrasive article comprising: a bonded abrasive body including: a bond material comprising an inorganic material; abrasive agglomerates contained in the bond material, wherein the abrasive agglomerates comprise at least about 70 vol % and not greater than about 90 vol % abrasive particles for a total volume of the abrasive agglomerates; a porosity of at least about 52 vol % and not greater than about 58 vol % of a total volume of the bonded abrasive b…
