The number of parts made of ceramic materials has gradually been increasing in field of from mechanical engineering to electronics engineering and, mechanical engineering ceramics have spread because of three very favourable characteristic features of their application, namely, heat, wear, and corrosion resistance. therefore, the elaboration of suitable grinding technologies is Important. grinding is problematic because crack-free ceramics are difficult to process owing to their particular micro structure. In this paper we report on the application of advanced precision grinding process, elaborating continuous wheel dressing. The removal rate can be increased significantly and surface roughness is improved. Various problems(roughness, ground surface etc)encountered in grinding of ceramics are also discussed.
