This paper presents a basic research for improving the dressability of metal bonded CBN wheels. A dressing experiment with CBN grinding segment has been conducted to investigate fundamentally the infuluence of tin content on the dressability of bronze bonded CBN wheels. Main results obtained in this paper are as follows : (1) A remarkable improvement in dressability of bronze bonded CBN wheels is achieved with increasing Sn content R more than about 40 wt%. (2) The removal mechanism of bond surface in dressing high tin bronze bonded wheels with R more than 40 wt% depends on not only ductile removal action such as plastic abrasion and micro cutting, but also brittle removal action such as grain boundary fracture of bond.
