Introduce the material characteristics of tungsten steel round fox milling cutter
The material characteristics of tungsten steel arc milling cutters mainly include the following aspects:Sources：www.bsztq.com.cn | PublishDate：2025.05.13
1. High hardness and strength
Tungsten steel is an alloy composed of hard phases such as tungsten carbide (WC) and bonding phases such as cobalt (Co). Tungsten carbide has a high hardness, reaching HRA90-95, which is much higher than ordinary steel. This allows tungsten steel arc milling cutters to easily cut various metal materials, including alloy steel and stainless steel with high hardness.
Cobalt, as a bonding phase, firmly binds tungsten carbide particles together, endowing tungsten steel with high strength and enabling it to withstand significant cutting forces. Under high-speed and heavy-duty cutting conditions, it is less prone to fracture or chipping.
2. Good wear resistance and corrosion resistance
The microstructure of tungsten steel is dense, and tungsten carbide particles are small and evenly distributed. During the cutting process, it can effectively resist wear, and the wear rate is much slower than ordinary tool materials. Therefore, tungsten steel arc milling cutters can maintain the sharpness and cutting size accuracy of the cutting edge for a long time, reduce the frequency of tool replacement, and improve machining efficiency.
At the same time, tungsten steel also has a certain degree of corrosion resistance, which can resist the erosion of cutting fluids, moisture and oxygen in the air on cutting tools, and extend the service life of cutting tools. Especially in some harsh processing environments, such as processing materials containing corrosive media or processing in humid environments, the corrosion resistance advantage of tungsten steel is more obvious.
3. High heat hardness and red hardness
Tungsten steel has a high melting point and good thermal stability, and can maintain its hardness and strength even in high temperature environments. During the cutting process, a large amount of cutting heat is generated due to the friction between the tool and the workpiece. Ordinary tool materials are prone to softening at high temperatures, leading to a decrease in cutting performance. Tungsten steel arc milling cutters can maintain good cutting performance at high temperatures and are not easily softened or deformed due to high temperatures.
Red hardness refers to the ability of cutting tools to maintain hardness and cutting performance at high temperatures. Tungsten steel has better red hardness and can generally maintain high hardness at high temperatures of 500-600 ℃, which makes it perform well in machining methods that generate a large amount of heat, such as high-speed cutting and dry cutting.
4. Good cutting performance
The hardness and wear resistance of tungsten steel arc milling cutters enable them to maintain a sharp edge during cutting, and the cutting edge can quickly cut into the workpiece material, reducing the generation of cutting force and cutting heat. At the same time, due to the high strength and toughness of tungsten steel, the cutting tool is not prone to vibration and deformation during the cutting process, which can ensure the stability and accuracy of cutting, thereby improving the surface quality of machining and reducing surface roughness.
