Tungsten steel cutting tools and their characteristics
Tungsten steel (Cemented Carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc. Especially its high hardness and wear resistance, even at a temperature of 500 ℃ is basically unchanged at 1000 ℃ still has a high hardness.
Cutting tools are tools used for cutting and processing in mechanical manufacturing, also known as cutting tools. The vast majority of cutting tools are machine-made, but there are also hand-made. Since the tools used in mechanical engineering are basically used for cutting metal materials, the term “tool” is generally understood as metal cutting tools. Tools for cutting wood are called woodworking tools. There is also a special category of tools used for geological exploration, well drilling, mine drilling, called mining tools.
Tungsten carbide blades, also known as tungsten carbide blades, which includes foot cutter blades, V-CUT blades, slitting blades, CNC blades, foot cutter blades, such as tungsten carbide, also known as tungsten carbide as the material of the electronic industry blades.
Material Performance Edit
Tungsten steel cutting tools are mainly made of integral tungsten steel as the matrix, which is refined through several production processes.
Tungsten steel, also known as Cemented Carbide, is made of high-quality tungsten carbide + cobalt powder by pressing and sintering after mixing with the formula ratio, which has high hardness, high strength, high wear resistance and high elasticity modulus, and belongs to the powder metallurgy industry. Cemented carbide as the teeth of modern industry, carbide cutting tools play a fundamental role in promoting the development of manufacturing industry. Tungsten steel can be divided into common tungsten carbide, fine grain tungsten carbide and sub-fine, ultra-fine grain tungsten carbide, and newly introduced double crystal tungsten carbide according to the grain size distinction. Distinguished by the main chemical composition, can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Tungsten carbide-based cemented carbide including tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and the addition of rare carbide (YW) three categories, they have their own strengths and weaknesses, the main component of tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NbC), etc., commonly used in the metal bonding phase is Co. titanium carbide-based Cemented Carbide is a Tic-based cemented carbide as the main component, commonly used in the metal bonding phase Mo and Ni. Cemented carbide has a high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC) is second only to diamond, good thermal hardness (up to 900 ~ 1000 ℃, keep 60HRC); high flexural strength (MPa5100), good impact toughness and corrosion resistance very high chemical inertia, and other general alloy blades do not have the characteristics.
