Abstract
In this study, experiments of high speed grinding had been earned out in a STD11 specimen for evaluating the grindability with designed CBN grinding wheels Ground surfaces were analyzed and evaluated by means of surface Integrities and wheel damages. The surface roughness and 3 dimensional profile had been used for analyzing the micro-surface integrity. The residual stress of the ground surface had been measured by the x-ray diffraction method. Also, the surface state of the ground specimens and the grinding wheels were evaluated by a metallurgical microscope and SEM system after high speed grinding in order to choose the suitable machining conditions.
