Negative angle blades
Cutting tools are used for cutting tools in mechanical manufacturing, also known as cutting tools. The vast majority of knives are machine, but there are also hand. Since the tools used in mechanical manufacturing are basically used for cutting metal materials
The material of the tool must have high high temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical inertness, good process (cutting, forging and heat treatment, etc.), and not easy to deform. Usually when the material hardness is high, the wear resistance is also high; the bending strength is high, the impact toughness is also high. However, the higher the hardness of the material, the lower the flexural strength and impact toughness.
According to the needs of the development of the manufacturing industry, multi-functional composite tools and high-speed tools will become the mainstream of tool development. In the face of an increasing number of difficult-to-machine materials, the tool industry must improve tool materials, develop new tool materials and more reasonable tool structures. Cemented carbide materials and coating applications increased.
