BONDED ABRASIVE ARTICLES, METHOD OF FORMING SUCH ARTICLES, AND GRINDING PERFORMANCE OF SUCH ARTICLES

摘要

An abrasive tool having a bonded abrasive body including abrasive grains contained within a bond material comprising a metal. During a grinding operation, the bonded abrasive body has a power variance [(Po−Pn)/Po]×100% of not greater than about 40%, wherein Po represents the grinding power to grind a workpiece with the bonded abrasive body at an initial grinding cycle and Pn represents the grinding power to grind the workpiece for a nth grinding cycle, wherein n>4.
