<p>#CMT# #/CMT# The tool comprises filamentary sol-gel alumina abrasive grain having length-to-cross sectional width aspect ratio of greater than about 1.0, agglomerated abrasive grain granules including abrasive grains held in three dimensional shape by a binding material and at least about 35 volume percent porosity. #CMT# : #/CMT# An independent claim is included for manufacturing method of bonded abrasive tool. #CMT#USE : #/CMT# For bonded abrasive tool such as ALTOS (RTM: high performance ceramic aluminum oxide grinding wheel), for grinding finishing of metal workpiece. #CMT#ADVANTAGE : #/CMT# Improves surface finish quality of workpiece. Minimizes heat generation in grinding zone. Reduces risk of damage of the tool. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a photographic view of the bonded abrasive tool. #CMT#INORGANIC CHEMISTRY : #/CMT# The agglomerated abrasive grain granules includes abrasive grains selected from fused alumina, non-filamentary sintered sol-gel alumina, sintered bauxite, cofused alumina-zirconia, sintered alumina-zirconia, silicon carbide, cubic boron nitride, diamond, flint, garnet, boron suboxide, and aluminum oxynitride. The binding material is a vitrified bon composition comprising fired oxide composition of silicon dioxide, boric oxide and aluminum oxide.</p> |
