Abstract
A method of providing a cold-worked sealing surface on the annular face of an annular seal ring is disclosed. The seal ring is mounted in a rotatable holder with the annular face exposed. While the holder is rotated, a work tool with a plurality of shot-impregnated flaps is also rotated. The axis of rotation of the work tool and holder are displaced 90.degree.. During rotation, the holder and flaps are placed in interfering relationship so that the annular face is cold-worked by the shot-impregnated flaps. The opposite annular face of the seal ring can be worked in the same manner.
