ABSTRACT:
A wavy face ring having a smooth face and a method of manufacturing this wavy face ring. In particular, the method includes providing a ring blank having a face surface and a peripheral surface and applying a predetermined force to the peripheral surface of the ring. This force deforms the face surface of the ring blank into a first deformation pattern. The face surface of the ring blank is then treated while the force is being applied to the peripheral surface of the ring blank. Finally, the force is removed from the peripheral surface of the ring blank to allow the face surface of the ring to relax and assume a second deformation pattern. A wavy face ring assembly is also provided that includes opposing rings mounted about a rotating shaft. One of the rings is stationary with respect to the other and one of rings has a wavy face treated by a lapping machine. The ring can be a seal ring or a thrust ring.
