ABSTRACT:
A balancing apparatus, particularly for a grinding wheel, whereby the wheel has four individual chambers disposed around its axis of rotation with each chamber connected to one face of the ring shaped container by a slot formed in a circular recess at a different radius so that the wheel can be balancing by injecting cooling fluid or the like into the slots to temporarily add fluid to selected chambers, and each chamber is separated from adjoining chambers by dividing walls which extend from inner to outer ring. The inner ring is tapered toward a central opening to ensure complete emptying after balancing.
