Mirror Grinding using cBN Vitrified Wheel Prepared by Micro-Dressing

Abstract

This paper deals with the mirror grinding using cBN vitrified wheel prepared by micro dressing, that is conducted under smaller dresser depth of cut and smaller dressing lead using a fine grain diamond dresser. Flat surface consisted of ductile smooth surfaces and a lot of minute brittle dents, is formed on the top of cBN grain cutting edge by the micro dressing using a fine grain diamond dresser of grain size #1200. Mirror surface with a roughness of 0.3 µm Rz is formed using cBN wheel working surface prepared by this micro dressing.
