How To Improve The Durability Of High-speed Steel Cutting Tools?

For complex high-speed steel cutting tools such as broaches, hobs, reamers, and milling cutters, carbon, nitrogen, sulfur, boron, oxygen and other elements are co-infiltrated under low temperature conditions to increase the durability of the cutting tools by an average of 2 to 5 times. times. This is because after these elements penetrate into the surface of the cutting tool, the chemical composition of the surface of the cutting tool changes, which reduces friction and self-lubrication during the cutting process, thereby reducing the cutting force and cutting heat, improving the durability of the tool, and reducing the production costs.
This process is simple and the working temperature is low. It is an effective measure to improve the durability of complex high-speed steel cutting tools.
