Abstract

The invention relates to mechanical engineering technology, in particular, is intended for machining shafts on lathes. The purpose of the invention is the expansion of technological capabilities by fastening parts of various sizes. The drive gear elliptical rollers are rigidly mounted on axles 6, perpendicular to the tapered surface 3, and mounted on radially movable sliders 8, spring loaded 10. The installation of the drive rollers for processing small diameters of parts is performed automatically when the end 15 of the part 15 is moved to the front Center 2. 5 Il.
