Roll tooling suppliers vary, the ways they work the tube vary, and therefore their products vary. The yield also varies. "The surface of a roll has a continuously changing radius, so the rotational velocity of the tooling varies over the face of the tool," he said. The tube moves through the mill at just one velocity, of course.
