Patent ID: 7578724

Claim:
A mechanical device for lapping a metal working surface, the device comprising: (a) a metal workpiece having the working surface; (b) a lapping tool including a polymeric material having a polymeric contact surface, adapted and positioned such that said contact surface is disposed generally opposite said working surface, said contact surface for moving in a relative motion to said working surface; (c) a plurality of abrasive particles, said particles disposed between said contact surface and said working surface, and (d) a mechanism, associated with at least one of said working surface and said contact surface, adapted to apply said relative motion, and further adapted to exert a normal load on said contact surface and said working surface, said contact surface for providing an at least partially elastic interaction with said plurality of abrasive particles, wherein, associated with said contact surface is a solid lubricant, and wherein, upon activation of said mechanism, said relative motion under said load causes a portion of said abrasive particles to penetrate said working surface to produce a tribological work surface, and wherein said relative motion under said load mechanically transfers said solid lubricant from said contact surface to the metal working surface.
