ABSTRACT:
A method of producing precision abrasive articles by electroforming for use in metal removal operations. In this method abrasive particles are packed firm between the inner circumferential surface of a mold and a centrally located metallic grid. Electrolyte for metal deposition is then introduced into the space containing the abrasive particles. An electrical cathode connection is made to the mold and an anodic connection made to the anode. Metallic deposition around the abrasive articles occurs on the inner annular surface of the mold and continues until a matrix supporting the abrasive particles is formed. The mold with the matric is then removed to receive core material, and the core is then machined to finished dimensions. The method is carried out at low temperatures and without any movement of the mold.
