【Abstract】 A new mechanical model of the vibration between the workpiece and the main spindle caused by the grinding wheel unbalance is proposed in this paper. Based on the theoretical analysis of the ground surface waviness growth, applying the technique of the liquid compensation of the dynamic unbalance of a grinding wheel, this paper researches the effect of the dynamic unbalance of a grinding wheel on surface waviness. The experiment results have indicated that the technique of the liquid compensation of the dynamic unbalance of a grinding wheel on line can be used for reducing the ground surface waviness.更多还原
