Study on Improving Cutting Tools Lifespan of W₆Mo₅Cr₄V₂ High-Speed Steel

Abstract:

This paper mainly discusses the technique of using quenching at 1000°C and tempering at 650°C for 2 hours to replace the heat treatment process of quenching at 1225°C and tempering at 560°C for 1 hour for three times.Due to the old heat treatment process is traditional multifarious waste energy and relatively backward.The experiment results prove that after the new treatment using the W6Mo5Cr4V2 high-speed steel to make cutting tools such as cutters, drill, taps and so on. It aslo achieves better abrasion resistance and ductility. This meeting the objective of improving the wear resistance, toughness, lifespan enhancement and energy conservation.It opens up a new way of simple and energy saving for W6Mo5Cr4V2 high-speed steel heat treatment process.The material of W6Mo5Cr4V2 high-speed steel has certain value to research.
