1 Preface Grinding wheel turning strength is one of the most important quality indicators of grinding wheel products. Grinding wheel turning testing machine is the necessary testing equipment for testing the revolving strength of grinding wheel. With the improvement of mechanical processing industry, the use of grinding wheels is getting higher and higher. As production, dosage. Large export volume of grinding wheel, the use of linear grinding wheel speed from 50-60m / s gradually to 80m / s direction, which is mainly with the
