Abstract

Background. The study on the technological process of thin cubanite abrasive grinding of wear-resistant composite parts, synthesized on the base of utilized and regenerated industrial wastes of nickel alloys XH55BMTKЮ, XH50BTФKЮ, ЭП975 with additions of hard lubricant CaF2 has been carried out.

Objective. The purpose of the work is the experimental research of surface cold-work strengthening parameters by thin cubanite grinding of friction parts made of new composite materials based on nickel and identification of influence on surface cold-work strengthening parameters of part surface roughness of the cubanite instrument, its bond type, and cutting modes.

Methods. Surface treatment of printing machines wear-resistant parts based on nickel on precision grinding machine with cubatine grinding instruments with granularity 14–20 µm on Br1 bakelite resin bond at 100 % concentration of cubanite and application of thin cutting modes.

Results. It was demonstrated that granularity, the cubanite disc bond material and parameters of thin cubanite grinding essentially influence surface cold-work strengthening parameters of the machining area. The cubanite grinding discs with granularity 14–20 µm on bakelite resin bond at 100 % concentration of cubanite provide the best performance of surface cold-work strengthening level, deterioration of the second type and the surface cold-work strengthening depth that meet the high requirements at work surfaces of friction parts for printing machines.

Conclusions. It was demonstrated, that the formation of high quality friction surface parts, made of new composite materials based on nickel essentially depends on the composition of cubanite instrument (granularity, bond type), and cutting modes. The recommendations on the production were developed.
