Cylindrical Plunge Grinding Process of Sialon

Cylindrical plunge grinding process and surface generation process of Sialon are experimentally investigated with bronze bond diamond wheel, analyzing grinding force, surface roughness, wheel wear, ground surface and so on. Main conclusions obtained in this study are as follows: (1) In a cylindrical plunge grinding process of Sialon with bronze bond diamond wheel, there are three distinct grinding processes such as spark-in, steady and spark-out. (2) Ground surface is formed by plastic deformation as well as brittle fracture in grinding Sialon. (3) Diamond grain primarily wears in attrition. (4) Grinding force increases with an increase of setting depth of cut, while surface roughness is hardly influenced by setting depth of cut.
