Advantages and functions of cemented carbide over high-speed steel
Cemented carbide has high hardness, strength, wear resistance and corrosion resistance, and is known as "industrial teeth". It is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts, and is widely used in military, aerospace and aviation , Mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, the market demand for cemented carbide continues to increase. And in the future, the manufacturing of high-tech weapons and equipment, the advancement of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for high-tech and high-quality and stable cemented carbide products.
The characteristics of cemented carbide
Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500 ℃. It still has a high hardness at ℃. However, cemented carbide is brittle and cannot be cut, and it is difficult to make integral tools with complex shapes. Therefore, inserts of different shapes are often made, and they are installed on the cutter body or mold body by welding, bonding, mechanical clamping, etc.
The role of cemented carbide
Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used for cutting Hard-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
Cemented carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasive tools, cylinder linings, precision bearings, nozzles, metal molds (such as wire drawing molds, bolt molds, nut molds, and Various fastener molds, the excellent performance of cemented carbide gradually replaced the previous steel molds).
Advantages of cemented carbide over high-speed steel
The cutting speed of cemented carbide tools is 4 to 7 times higher than that of high-speed steel, and the tool life is 5 to 80 times higher. Manufacturing molds and measuring tools has a life span of 20 to 150 times longer than that of alloy tool steel. It can cut hard materials of about 50HRC.
