    Roll Forming What Is It Process Benefits Types Metals

    D Ring Rolling. In ring rolling, a ring of small diameter workpiece is rolled between two rollers to form a ring of larger diameter. One roller is the drive roller, while the other roller is idle. An edging roller ensures that the metal will have a constant width. The reduction in width of the ring is compensated for by the diameter of the ring.
