Metal Processing

Metal cutting blades are important tools in modern machining. Whether it is an ordinary machine tool, or a CNC machine blade and a machining center machine blade, it must rely on the cutting tool to complete the cutting work. When cutting, the cutting part of the tool not only bears a large cutting force, but also bears the high temperature generated by the deformation and friction of the cutting eyebrow. In order for the blades to work under such conditions without being deformed or damaged quickly, and to maintain its cutting ability, the blades material must have high high temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical properties. Inert, good processability (cutting, forging and heat treatment, etc.), not easy to deform, usually when the material hardness is high, the wear resistance is also high; when the bending strength is high, the impact toughness is also high. But the harder the material, the lower its flexural strength and impact toughness. High-speed steel is still the most widely used cutting blades material because of its high bending strength and impact toughness, as well as good machinability, followed by cemented carbide. Secondly, the cutting performance of the blades depends on whether the geometric parameters of the cutting part and the selection and design of the blades structure are reasonable.
