ABSTRACT:
Bonded abrasive tools, having novel porous structures that are permeable to fluid flow, comprise a relatively low volume percentage of abrasive grain and bond, and a relatively low hardness grade, but are characterized by excellent mechanical strength and grinding performance. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.
