ABSTRACT:
A grinding wheel having a hollow balance ring embedded in the grinding wheel material about the arbor hole. Steel shot partially fills the balance ring and automatically moves to a position to dampen any rotating imbalance in the grinding wheel both when it is new and as it wears. The balance ring can also function as a substitute for the conventional fracture or safety ring in the grinding wheel.
