Abstract (en)
[origin: US5885149A] An abrasive tool and a method for its manufacture is provided in which the structural body of the tool, including both the central core and the outer, abrasive-containing portion, is fabricated of a homogeneous material, with abrasive particles dispersed throughout the consumable abrasive-containing portion to grindingly remove workpiece material during rotation of the structural body. A porous lattice of diamond grains encased in a cladding material is first formed by sintering as a continuous annulus or as arcuate segments. The skeletal lattice is then placed in a mold and a homogeneous material in liquid state is introduced into the mold to simultaneously form the central core and to flow into at least a portion of the porous lattice of clad diamond grains to provide an integrally molded, unity tool when the core material solidifies.
