抄録

At present, grinding, cutting and lapping using a correcting carrier can all be used to recover the accuracy of a deteriorated lapping plate. The lapping method using a correcting carrier is simpler than the grinding and cutting methods. However, as the deteriorated condition of the lapping plate changes with machining conditions, the best correcting conditions have to be selected in this method in order to recover the deteriorated lapping plate. In the present paper, it is supposed that the wear volume of the lapping plate using this method is proportional the relative frictional distance of both parts, and a theoretical analysis of the lapping plate and the correcting carrier is conducted. As a result, it becomes clear that approximate agreement between observed and calculated values is obtainable under the some conditions. When the inner diameter of the correcting carrier is 1.67 times or more the width the lapping plate, frictional distance characteristics become comparatively flat.
