ABSTRACT:
A mechanical device for lapping, and a method therefore, the device including: (a) a metal workpiece having a metal working surface; (b) a contact surface, disposed generally opposite the working surface, for moving in a relative motion to the working surface; (c) abrasive particles disposed between the contact surface and the working surface, and (d) a mechanism, associated with the working surface and/or the contact surface, for applying the relative motion, and for exerting a load in a substantially normal direction to the contact surface and the working surface, the contact surface for providing an at least partially elastic interaction with the plurality of abrasive particles, wherein, associated with the contact surface is a particulate additive, and wherein, upon activation of the mechanism, the relative motion under the load causes a portion of the abrasive particles to penetrate the working surface, and wherein the relative motion under the load effects incorporation of a portion of the particulate additive into the metal working surface.
