Improving the efficiency of the cutting tool based on its modification

Currently, carbide cutting tools are mainly used for processing blanks of machine parts. Increasing the working life plates is one urgent tasks in mechanical engineering. The paper proposes to increase due complex modification surfaces tool. Modification tool surface proposed be carried out on basis electron beam alloying with an alloy based niobium and hafnium, followed by application a wear-resistant coating titanium aluminitride.
