Wear resistance of metal-cutting tools and formation of secondary contact structures during cutting

This article presents the results of research funded by Committee Science Ministry and Higher Education Republic Kazakhstan (grant № AP14972884 "Increasing wear resistance metal-cutting tools method lapping"). There was investigated state tools' problem in conditions machine-building enterprises (RK). It is revealed that do not always endure durability period according to standards are exposed premature cutting edges, breakage, chipping. The factors affecting existing possibilities for their improvement also studied. proposes pretreating order improve under domestic industries. formation secondary structures on working surfaces tools, which one manifestations fundamental law - structural adaptability studied basis analysis previously conducted works.
