Study on Roundness Error Correction for the Ceramic Ball in Rotated Dual-Plates Lapping Process

The correction process of balls roundness error during lapping is discussed qualitatively. Dynamic analysis for rotated dual-plates lapping mode of ceramic balls is performed, under the assumption of a fluid loading system. The effect of the damping of the loading system on the correction of balls roundness error is discussed. And the result shows large damp causes an increase of magnification of load, and improves the correction of roundness error of balls.
