The paper presents influence of the vibro-abrasive machining on the operating parameters of the surface and polishing the surface of components made of steel X160CrMoV121 (NC11LV). There were used Rollwasch smoothing media made of nickel-chromium steel SB 3,1 lotto series. The process was carried out by using supportive liquid series FE-L120-B32/R. Analyzed the influence of micro machining process metal fittings on the conditions of technically dry friction. The tribological tests were performed on testing machine T-01 M Ball-on-disk. The balls used for tests were made of steel 100Cr6, the study carried out for the sliding distance of 1000 m with force 10 N. Compared the coefficients of friction technically dry before vibro-abrasive machining (samples directly after grinding) and after vibro-abrasive smoothing.Keywords: micro machining process, vibro-abrasive machining, rotofinish, surface roughness, tribological tests
