nd. Microgeometry surface features of wear-resistant friction parts of new composite alloys 11Р3АМ3Ф, 85Х6НФТ, 4ХМФТС, Р6М5Ф3, and 4Х2В5МФ, which contain such chemical elements as titanium, wolframium, molybdenum, and vanadium with CaF2 increments and its influence on quality parameters. Objective. The purpose of this paper is to determine the quality parameters provided for superfine superfinishing of machine systems friction parts, which contain such chemical elements as titanium, wolframium, molybdenum, and vanadium with CaF2 increments and studied the influence of abrasive superfinishing quality parameters and surfaces of friction precision. Methods. Surface treatment of high-alloyed friction parts based on die steel and tool steels wastes with abrasive superfinishing. Results. The research results of thin technological processes of superfinishing and formation of the surfaces parts, which were manufactured of new composite materials on the base of die steel and tool steels wastes and which contain such chemical elements as titanium, wolframium, molybdenum and vanadium were presented in the article. It was defined that the dependence of the quality of composite parts surface is determined by composition of the abrasive hones, their grain, bond type of superfinishing tools and parameters of cutting. These recommendations meet the quality requirements of the friction surfaces of working surfaces of parts. Recommendations for the choice of the abrasive hones for industrial engineering companies have been developed.Conclusions. It was shown that high quality parameters of friction surfaces of the parts, for example, the pressure tensions and micro-hardness of the surface layer and other quality parameters are formed as result of interaction between cutting modes and friction-polishing by abrasive hones and such factories as granulocyte and properties of abrasive tools for the fine superfinishing technology. Also was shown that the best results can be achieved with using hones on the base of green carbid cremnium on the elastical gliftalical bond with the abrasive grit 7–14 mkm (63CM7CM2Гл, 63CM14CM2Гл) and thin parameters of cutting.
