A Study on Correcting Techniques for Recovering the Accuracy of a Deteriorated Lapping Plate using a Correcting Carrier : Corrective Characteristics owing to Lapping Pressure Influence

Abstract

At present, the accuracy of a deteriorated lapping plate may be recovered by cutting and grinding, or by using a correcting carrier. A correcting carrier is simpler to use than the grinding method and is generally employed at many factories. How-ever, as the deteriorated condition of the lapping plate changes with machining conditions, optimal correcting conditions must be selected in order to recover the deteriorated lapping plate. In this paper, the wear characteristics of a lapping plate with a correcting carrier are analyzed theoretically and confirmed experimentally. It is confirmed that deteriorated lapping plates can be restored by means of this method.
