Performance of Various Grinding Wheels in Grinding Hardened Steels

Abstract

<p>In this thesis an attempt is made to study the grinding wheel wear phenomena by analyzing the cutting force patterns, wheel wear and wear particles removed from the wheel.</p> <p>Results of measurements of grinding forces and wheel wear, in addition to the scanning electron microscope observations, are presented for grinding hardened M2 tool steel and 52100 bearing steel. Plunge-type surface grinding tests were performed with different grade hardness wheels of aluminum oxide grains in vitrified bond.</p> <p>Contrary to common belief, all wheels tested were found to maintain their grinding capability, during a long grinding operation. The method proposed, for evaluating the performance of grinding wheels from force pattern and grinding wheel wear, appears to present a clear picture of the wear phenomenon. And the method could be adopted for the selection of grinding wheels.</p>
