Abstract
A grinding tool and method is provided for shaping an edge of sheet glass. The grinding tool includes an arbor and a wheel being of a unitary construction and including an axis of rotation. The grinding tool further includes a recess extending along a periphery of the wheel, with a bonded abrasive being disposed therein. The bonded abrasive is sized and shaped for being profiled, to shape an edge of a glass sheet upon rotation of the tool about the axis. The bonded abrasive may further be sized and shaped for being re-profiled after use. The grinding tool of this invention may provide for both improved quality and reduced cost sheet glass.
