Quality assurance for the production of metal-cutting tools from high-speed steels

Abstract

Abstract The paper presents an analysis of the state of metal cutting tools production in Russia, and it provides an assessment of the main trends in the development of this industry on the example of tools produced under conditions of domestic engineering enterprises. The developed and tested methods of quality control of high-speed steels of traditional and powder versions are described. Based on the undertaken studies, typical structural defects of high-speed steels in the delivery state and after heat treatment are identified. Recommendations aimed at improving the tool quality were developed and formulated taking into account an analysis of their operating conditions and in accordance with specific conditions of production and quality of steels in the delivery state. A methodological approach to solving the problem of improving the quality of metal-cutting tools made from traditional and powdered high-speed steels is presented.
