A mechanical device and method for lapping a metal working surface, the device including: (a) a workpiece having the metal working surface; (b) a contact surface, disposed generally opposite the working surface, for moving in a relative motion to the working surface; (c) a plurality of abrasive particles, disposed between the contact surface and the working surface, and (d) a mechanism, associated with at least one of the surfaces, for applying the relative motion, and for exerting a load on the contact surface and the working surface, the contact surface for providing an at least partially elastic interaction with the abrasive particles, wherein, associated with the contact surface is a particulate additive material, and wherein, upon activation of the mechanism, the relative motion under the load causes a portion of the abrasive particles to lap the working surface, and wherein the relative motion under the load effects incorporation of a portion of the particulate additive material into the working surface.
L'invention porte sur un appareil mécanique de rodage de surfaces métalliques comportant: (a) une pièce comprenant la surface à usiner; (b) une surface de contact sensiblement opposée à la surface à usiner et se déplaçant par rapport à la surface à usiner; (c) des particules abrasives disposées entre la surface de contact et la surface à usiner, et (d) un mécanisme associé à au moins l'une des deux surfaces, lui appliquant un mouvement relatif et exerçant une charge sur la surface de contact et la surface à usiner, la surface de contact produisant une interaction au moins partiellement élastique avec les particules abrasives. Un matériau additif particulaire est associé à la surface de contact. Lors de l'activation du mécanisme le mouvement relatif sous charge amène une partie des particules abrasives à roder la surface à usiner, et une partie du matériau additif particulaire à s'incorporer à la surface à usiner.
