Abstract

The paper deals with the issues of increasing the operational properties of metal-cutting tools during blade turning of stainless steel and heat-resistant alloy on the basis of using the mechanism of metal-polymer compounds formation. It is noted that the formation of such compounds during blade machining of metals by cutting is carried out through the use of activated corona discharge, which provides a complex effect on the contact processes of the surface layer of metal-cutting tools with nanostructured wear-resistant coatings. According to the results of experimental researches the increase of wear resistance of hard-alloy tool by 30 % at application of dry electrostatic cooling and lubricating-cooling technological media with oxygen-containing polymeric additives, and also increase of period of durability of metal-cutting tool with nanostructured wear-resistant coatings is established. The possibility of providing the greatest efficiency at their complex application in machine-building production is confirmed.
