An unbalanced grinding wheel produces an uncompensated centrifugal force which induces a relative vibratory motion between wheel and workpiece. The visible chatter patterns which often occur on ground surfaces are attributed to this relative motion. Therefore, the periodical balancing of the grinding wheel is necessary to produce good surfaces. Two methods, which are applying the principle of centrifugal balancing, and are named Nomograph method and CAB method, have been developed. After the balancing operation by these new methods the residual unbalance was measured. The results of the experiments indicate that the Nomograph method is capable of balancing handily without trial and error and the CAB method is practicable to reduce the residual unbalance nearly to the noise level of measuring instrument.
