New coating materials for high performance cutting tools

Objective

At present high speed cutting technology is the most promising approach to increase both efficiency and precision of metal cutting processes. However there are new alloys especially difficult for machining, for instance, hardened steels used for moulds, Cr-Co alloys used for prosthesis, Ti-based, and Ni-based alloys used in gas turbines and in the aerospace industry, where high speed cutting technologies are meeting serious difficulties to be introduced. On the other hand, there are important environmental and health reasons to reduce consumption of cutting fluids used as lubricant and refrigerant agents during the cutting process. The aim of the project is to develop a new generation of complex-shape tools, made of WC-Co hard metal and coated with layers based on the B-C-N system, able to be used for high speed machining of these materials in different operations (milling, broaching, reaming, etc.).
