Vitrified bonded abrasive bodies prepared from sol-gel sintered aluminous grit particles, a vitreous bond, bubbled alumina, and a sacrificial organic material exhibit improved abrasive performance, especially for creepfeed grinding products.

High porosity vitrified bonded grinding wheels

Vitrified bonded abrasive bodies prepared from sol-gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by coating the surfaces of the grit particles with a metal oxide, preferably by means of an organofunctional metal-containing surfactant having a metal content of at least about 10 weight percent.

Vitrified bonded finely milled sol gel aluminous bodies

Vitrified bonded abrasive bodies prepared from sol gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by treating the surfaces of the grit particles so as to give them silica-enriched surfaces.

Vitrified bonded sol gel sintered aluminous abrasive bodies

Nitrified bonded sol gel sintered aluminous abrasive bodies

A grinding wheel is disclosed which is made up of sintered aluminous abrasive and a vitrified bond, the vitrified bond being a frit. A large portion of the sintered aluminous abrasive may be replaced by a non-sintered abrasive and the bond may include fillers and/or grinding aids.
