Abstract
Background. Study on the technological process of thin abrasive grinding of wear resistance 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 processes of thin abrasive grinding of friction parts made of new composite materials based on nickel and identification of influence on the parameters of part surface roughness of the abrasive instrument type, its granularity and cutting modes.Methods. Surface treatment of printing machines wear-resistant parts based on nickel by thin grinding on the plain-grinding, round-external-finishing and internal-grinding machines with grinding instruments made of chromium electrocorundum (33A) with granularity 14–28 µm on the glyphtal bond and application of thin cutting modes.Results. It was show, that granularity, the abrasive instrument bond material and parameters of thin abrasive grinding essentially influence the parameters of surface roughness machining Ra. The best performance Ra parameters satisfy the grinding chromium electrocorundum 33A discs with granularity 14–28 µm on the glyphtal bond and thin cutting modes that meet the high requirements at work surfaces of friction parts for printing machines. Advantage of the surface machining with grinding chromium electrocorundum discs was shown.Conclusions. Also it was demonstrated, that the formation of high quality parameters of details surface, made of new composite materials based on nickel essentially depends on the type of the abrasive instrument, cutting modes of composites and bond material. The recommendations on the production were developed.

The purpose of the work is the experimental research of processes of thin abrasive grinding of friction parts made of new composite materials based on nickel and identification of influence on the parameters of part surface roughness of the abrasive instrument type, its granularity and cutting modes. Surface treatment of printing machines wear-resistant parts based on nickel by thin grinding on the plain-grinding, round-external-finishing and internal-grinding machines with grinding instruments made of chromium electrocorundum (33A) with granularity 14–28 μm on the glyphtal bond and application of thin cutting modes.

The best performance Ra parameters satisfy the grinding chromium electrocorundum 33A discs with granularity 14–28 μm on the glyphtal bond and thin cutting modes that meet the high requirements at work surfaces of friction parts for printing machines. Усе це вимагає від науковців і практиків всебічно дослідити процеси тонкого абразивного шліфування підшипників ковзання із нових композиційних матеріалів на основі використання відходів нікелевих сплавів та на цій основі розробити типові технологічні процеси для галузі поліграфічного машинобудування, що ілюструє актуальність вибраної теми досліджень
