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. |
