Abstract
On the superfinishing stone of fine grain, soft grade and sulphur treated, which have been recently employed to comply with the request for high stock removal together with lowest cost and high quality surface, an efficient utilization of the critical stone pressure Pc is emphasized again in this paper as an important characteristic concerned with actual performance for an advanced selection and manufacture of the well-fitted stone for the object. Chiefly from the finishing data of the bearing steel with stones of WA 3000 V (S) having various structure and hardness, the relations are discussed between stone specification and Pc, stone wear rate Wc/Pc, stock removal Tc or economic ratio Tc/Wc at the pressure of Pc. Consequently, it is proved that the user can almost appoint the right stone which holds excellent performances coincidently in Tc and Tc/Wc by Pc and the Rockwell hardness RH of the stone. In practice, this stone is desirable to be applied at the pressure of (0.8-0.9) Pc, for example, to secure a mirror finished surface of high quality and a stable stock removal. Furthermore, the universality of relationships between stone specification and the above characteristics and the possibility of selecting a fitted stone by the above procedure are checked up with three different examples in grain size, working material or conditions.
