Abstract
An ironing punch for ironing the socket of a ball-and-socket joint has a punch body with a plurality of circumferentially spaced ridges disposed on an outer circumferential surface thereof and extending from a distal end surface. The ironing punch also includes a plurality of ridge-shaped dies fitted respectively in recesses defined between the ridges on the punch body. Each of the ridges is ground by a single grinding wheel with the ridge-shaped dies removed from the punch body, and each of the ridge-shaped dies is also ground by a single grinding wheel. The punch body has relief grooves for preventing the grinding wheel from physical interference with junctions between the recesses and the distal end surface.
