Abstract
A process for the continuous chipless separation of identical individual rings from tubular workpieces by using cutting rollers. In order to produce highly-accurate rings, preferably from antifriction bearing steel, the section of the tubular workpiece to be separated is completely encompassed by the longitudinal contour of the cutting rollers and the faces of the rings are produced plane-parallel and vertical relative to the workpiece axis. What is essential is that prior to the cutting process the tubular workpiece is heated to a temperature that substantially lowers the deformation resistances of the material used.
