The tungsten steel cutting tool is mainly made of the whole tungsten steel as the matrix, after several production processes.
Tungsten steel, also known as hard alloy, is made of high-quality tungsten carbide and cobalt powder mixed by formula ratio through pressing sintering, with high hardness, high strength, high wear resistance, and high elastic modulus, belongs to the powder metallurgy industry. As an important factor to promote the development of the modern industry, hard alloy cutting tools play a fundamental role in promoting the development of the manufacturing industry. In order to make better use of cemented carbide tools, it can be ground before use. The best equipment for grinding is .
The tungsten steel cutting tool description
Tungsten steel can be divided into the ordinary hard alloy, fine grain hard alloy, subline grain hard alloy, and superfine grain hard alloy according to grain size. According to the main chemical composition of tungsten steel, it can be divided into tungsten carbide and titanium carbide.
Tungsten carbide includes tungsten cobalt class (YG), tungsten cobalt titanium class (YT) and added rare carbonization class (YW), which have their own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NBC) and other commonly used metal bonding phase is Co.Titanium carbide-based carbide is a hard alloy with Tic as the main component, and the metal bonding phase Mo and Ni are commonly used. The hard alloy has a high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC), second only to diamond, good thermal hardness (up to 900 ~ 1000℃, maintain 60HRC). High bending strength (MPa5100), good impact toughness and high corrosion resistance to chemical inert properties of general alloy blades do not.
