Abstract
Abrasive tools suitable for precision grinding of hard brittle materials, such as ceramics and composites comprising ceramics, at peripheral wheel speeds up to 160 meters/second are provided. The abrasive tools comprise a wheel core attached to an abrasive rim of dense, metal bonded superabrasive segments by means of a thermally stable bond. A preferred tool for backgrinding ceramic wafers contains graphite filler and a relatively low concentration of abrasive grain.
