ABSTRACT:
An abrasive surface for cutting and grinding tools and having abrasive particles embedded in a filler material. The abrasive surface is bonded to the perimeter edge of a rigid hub and has a circumferential dimension and a width dimension. The abrasive surface is divided along both the circumferential dimension and the width dimension into a plurality of hard regions and soft regions. The hard regions wear more slowly that the soft regions and so different patterns of hard regions and soft regions produce different cutting profiles. A method for fabricating the abrasive surface includes forming a laminated sheet from a plurality of laminated layers. Each laminated layer includes at least a layer of soft, easily deformable material and a layer of abrasive particles. The layers of abrasive particles can be formed into staggered rows to form the pattern of hard regions and soft regions. The layers of the laminated layers are sintered together to form the laminated sheet from which the abrasive surface is cut.
