The material of alloy cutting tools is mainly hard alloy, which is an alloy material made from hard compounds of refractory metals and bonded metals through powder metallurgy process. Hard alloys have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially being able to maintain high hardness and wear resistance even at high temperatures. This material is widely used in the manufacturing of cutting tools, such as turning tools, milling cutters, planers, drill bits, etc. It is suitable for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, as well as difficult to machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel.
The material properties of hard alloy cutting tools include high hardness, wear resistance, good strength and toughness, which make them excellent when used for cutting in mechanical manufacturing. Hard alloy cutting tools allow a cutting speed 5-10 times higher than high-speed steel cutting tools, but have lower bending strength and impact toughness, making them suitable for specific machining conditions and materials.
In addition, alloy cutting tools also include a type of steel that adds alloying elements such as chromium, molybdenum, tungsten, and vanadium on the basis of carbon tool steel to improve hardenability, toughness, wear resistance, and heat resistance. It is mainly used for manufacturing measuring tools, cutting tools, etc. Alloy cutting heads are suitable for rough turning, rough planing, rough milling, etc. on uneven surfaces and intermittent cutting of cast iron, non-ferrous metals and their alloys, and non-metallic materials.
