Past, Prsent and Future of Lapping and Polishing Machines (4)

Small machine newly proposed for studying polishing charactristics

Abstract

The removing ratio of glass lapping or lapping hardness, which was established in the JOGIS (The Japan Optical Glass Industry Standard), was discussed taking account of its applications. And the useful characteristic values for not only lapping but also polishing many work materials were re-proposed. These are the specific amounts of stock removal and tool wear (μm/m/Pa) which refer to proportional constants of work or tool loss relative to speed, pressure and working time during lapping or polishing. Then a small machine has been newly proposed to get such amounts of lapping and polishing.
