Internally safety reinforced cup grinding wheel

摘要

A resinoid bonded abrasive cup type grinding wheel with internal layers of safety reinforcing material integrally molded within, bonded to and tieing the central hub and sidewall portions of the wheel together. The safety reinforcement extends continuously, in a smoothly curved shape without sharp bends, generally radially outward through the central hub portion, and then generally axially and radially outward through the sidewall portion to an outer peripheral edge.
