Influence of the characteristics surface layer of the tool and composition technological lubricant on the coefficient of friction in methods combined mandreling of holes

Abstract

The influence of the nature and parameters microgeometry of the surface layer tool on the sliding friction coeffi cient in the combined methods opening under the conditions of using metal-coating lubricants, which implement the effect of wear-free friction of Garkunov—Kragelsky, is studied comparatively using the theoretical provisions of the adhesivedeformation theory of friction
