Title: Method of turning a rotating metallic workpiece

Abstract: A rotating metallic workpiece, the hardness of which lies within the interval of 45-65 HRC, is turned by a cutting insert while being rotated about an axis. The insert has a cutting edge made of cubic boron nitride. The cutting insert is fed in a feed direction into the rotating workpiece, by a distance which is shorter than an effective cutting edge length in order to cut a surface having a finish Ra of maximum 0.2 .mu.m. The ends of the cutting edge are situated outside the zone of contact with the workpiece.
