In the conditions of repair and mechanical production of chemical, oil, geological exploration and other sectors of the national economy of the Republic of Kazakhstan, there is a problem of improving the quality indicators and productivity of cutting in the manufacture of parts of bodies of revolution from various materials. The authors investigated the method of rotational friction turning of external cylindrical surfaces using a special cutting tool-a friction cup cutter. For processing by rotational friction turning, samples were prepared-blanks of various diameters and materials: steel 45, steel 20X, brass L63 and bronze BrAMts9-2. The workpiece samples were processed on 1K62 and JET GH-1640ZX screw-cutting lathes. As a result of processing by rotational friction turning, various forms of chips were obtained. When processing steel 20X, two types of chips were obtained: fracture chips and shearing chips. When processing steel 45, drain chips of various lengths were obtained. On the basis of metallographic studies of chip formation and the nature of the distribution of deformations in the chip formation zone, it was established that plastic deformation during rotational friction turning obeys the laws of traditional cutting. When machining non-ferrous metals, you can control the shape and size of the chips formed. The results obtained showed the wide technological possibilities of the developed resource-saving method of rotational-frictional turning of parts of bodies of revolution.
