METHOD OF MAKING ABRASIVE PRODUCTS, IN PARTICULAR GRINDING WHEELS, WITH WITREOUS BINDER AND ABRASIVE PRODUCTS, IN PARTICULAR GRINDING WHEELS, MADE THEREBY

摘要

A method for making vitreous bonded abrasive articles, particularly grinding wheels, is provided that includes the step of blending sugar/starch particles into the other ingredients for making the wheel. The sugar/starch particles are intimate combinations of sugar and starch. Wheels of improved performance are obtained compared to similar wheels made by a comparable method not including the step of blending sugar/starch particles into the abrasive grain, vitreous bond material and other components used for making the wheel.
