Milling cutter raw material comparison: high speed steel, carbide and diamond
In the manufacturing industry, the milling cutter is a very important tool and is widely used in various cutting processes. The quality and performance of the milling cutter depends on the choice of its raw material. At present, the raw materials of milling cutters mainly include high-speed steel, cemented carbide and diamond. Below we will conduct a detailed comparative analysis of these three materials.

High speed steel is a tool steel with high cobalt content, which is widely used in the manufacture of cutting tools because of its high hardness and wear resistance. High speed steel milling cutter has good heat treatment process performance, can maintain high hardness at high temperature, thus improving its cutting performance. In addition, high-speed steel also has good toughness and strength, and can withstand large cutting forces. However, the disadvantage of high-speed steel is that it is easy to oxidize and wear, requiring frequent replacement and maintenance.

Tungsten carbide (tungsten steel) is an alloy material composed of tungsten, cobalt, titanium and other elements, because of its excellent wear resistance and heat resistance and is widely used in the manufacture of milling cutters. Tungsten steel milling cutter has high hardness, high strength and high wear resistance, which can maintain good cutting performance when cutting at high speed and machining high hardness materials. In addition, tungsten steel also has good chemical stability and reliability, long service life, low maintenance costs. Compared with high-speed steel, tungsten steel has better thermal fatigue resistance and longer service life. Although the price of tungsten steel is slightly higher than that of high-speed steel, its excellent performance and long life make it a cost-effective choice.

Diamond is a kind of superhard material, which is widely used in machining various hard materials and precision machining fields. Diamond milling cutters have extremely high hardness, wear resistance and heat resistance, and can perform well in machining materials with high hardness, precision and high surface quality. The cutting speed of diamond milling cutter is fast, the processing efficiency is high, and the surface smoothness after processing is very high. However, the price of diamond is very expensive, and its processing and maintenance costs are relatively high. Therefore, diamond milling cutter is more suitable for special high-end applications.

In summary, high-speed steel, cemented carbide (tungsten steel) and diamond each have their advantages and disadvantages. When selecting milling cutter raw materials, it is necessary to comprehensively consider the specific application needs and processing conditions. For general applications, tungsten steel is a very cost-effective choice, with high hardness, high wear resistance, long life and low maintenance costs. For special high-end applications, diamond is more advantageous, but it needs to pay attention to its high price and cost.
