SELECTION OF A RATIONAL METHOD FOR HARDENING CARBIDE CUTTING TOOLS FOR HEAVY ENGINEERING

An important task is to improve cutting tools for high-precision productive machining of difficult-to-machine materials by applying the latest tool hardening methods. This is especially true for carbide-cutting tools. The paper analyzes the current state of the problem of improving the tooling of new machine tools for high-precision productive machining of hard-to-machine materials.

Investigation of the Carbide-tipped Tool Wear Hardened by Method of Aerodynamic Impact

Theoretical calculations and experimental studies of the influence of wear on the cutting process and the precision parameters of machining by hard alloys during milling are described in the article. The method of aerodynamic hardening is designed to increase the durability of tools, which are heterogeneous compositions of tungsten carbides, titanium and tantalum with cobalt ligature operating under severe process conditions with varying impact loads.
