In this paper, the retraction grinding method, in which the grinding wheel head gets rapidly back by very small amount immediately after beginning of spark-out state, is proposed for improving the taper error in the deep hole osciilation internal grinding. Main conclusions obtained are as follows : (1) It is made clear that by the retraction grinding method the taper error of workpiece can remarkably be improved with the fine surface roughness condition. (2) In the retraction grinding the taper generation mechanism is affected just by extending of spark-out g'rinding time due to a decrease of the residual stock due to the stiffness of the grinding wheel shaft and workpiece spindle. (3) By taking account of the periodic change of the normal grinding force linking to the oscillation movement, the measured taper can sufficiently be predicted.
