The axial closed-die rolling process is a partial forming process. Pre-rolled rings are placed in the rotating bottom die of the axial closed-die rolling machine. The top die, which also rotates, is inclined at an angle against the vertical axis. Depending on the construction, the dies are vertically adjusted and the ring is rolled in the impression. The rolling force required here amounts to only about 5 to 20% compared with a conventional closed-die forging press. Workpieces are rolled without flashes using the specially developed control system.
