Abstract

Method of manufacturing hollow, circular-shaped workpieces. A hollow ingot is formed by centrifugally casting chromium steel, a chemically heat-treatable steel, or from other steels. The centrifugally cast hollow ingots are formed using a rolling, forging or die-forging mechanism, the thus obtained tubes or annuli are divided into sections, and the sections are then profile-rolled, forged or die-forged, machined by metal cutting methods, subsequently heat-treated to obtain optimum hardness, and after tempering finished by grinding, superfinishing, lapping and polishing or by combination of these finishing methods.
