Milling cutter is an important tool widely used in the field of metal processing, and its material selection and use have an important impact on processing efficiency and machining quality. According to different application requirements, the material of the milling cutter can be divided into a variety of types, each material has its own unique performance and scope of application.

1, high-speed steel is a common milling cutter material, it is composed of steel and a small amount of alloying elements. High speed steel milling cutter has good heat resistance and wear resistance, which is suitable for processing low hardness metal materials and stainless steel. Because of its advantages of low cost and easy machining, high speed steel milling cutter has been widely used in the field of metal machining.

1. Cemented carbide is another commonly used milling cutter material, which is sintered from tungsten cobalt alloy and cemented powder. Carbide milling cutter can process high hardness materials, such as steel, cast iron, cast steel, stainless steel, etc. Due to its advantages of high hardness, high wear resistance and high impact resistance, carbide milling cutters have significant advantages in the processing of difficult materials.

3, ceramic and superhard materials are also important materials for milling cutters. Ceramic milling cutter is made of zirconia and other ceramic materials, with high hardness, high thermal stability, corrosion resistance and other advantages, suitable for processing high hardness materials and superalloys. The superhard material milling cutter has extremely high hardness and wear resistance, which is suitable for final finishing.

In general, milling cutters of different materials can adapt to cutting tasks of different materials. In actual use, the appropriate milling cutter needs to be selected according to the specific processing needs and material type. At the same time, it is also necessary to pay attention to the effects of cutting parameters, cooling methods and other factors on processing efficiency and processing quality.

In short, the material selection and use of milling cutters is of great significance to the field of metal processing. With the continuous development of science and technology, new milling materials and technologies are also emerging, providing more possibilities for the development of the metal processing field.
