The cutting forces at thin cubonit grinding of the wear-resistant composite nickel-based parts for printing machines

Abstract

Background. The investigation of the influence on the cutting forces rectangular components of technological factors at thin cubanite grinding of parts made of wear-resistant composite materials synthesized based on the use of recycled and regenerated waste products of nickel alloys XH55BMTKЮ, XH50BTФKЮ, ЭП975 with the addition of solid lub­­ricant CaF2 is presented. Objective. The purpose of the paper is the experimental research of cutting forces rectangular components of tech­nological processes of thin cubanite grinding of friction parts made of new nickel-based composite materials. The influence on the force field of grinding tool grain, such as bond type grinding discs and basic grinding modes, is determined. Methods. Surface treatment of printing machine friction parts made of wear-resistant nickel-based composites with thin grinding on the plain-grinding machines with cubonit grinding instruments with 14–20 µm grain on the bakelite-rubber bond Бр1 and use of the thin cutting modes. Results. It was show, that the granularity, grinding disc bond material and thin cubonit grinding modes essentially influence the cutting forces rectangular components P x , P y , P z at grinding of the new nickel-based composites. The cubonit discs with 14–20 µm grain on the bakelite-rubber bond Бр1 and use of the thin cutting modes provided the best results. Conclusions. It is proved that the grain and the grinding cubanite discs bond type and grinding modes significantly influence the formation of the force field at grinding of new nickel-based composite materials. The recommendations were developed for the production.
