Product Description Product DescriptionHigh Hardness Tungsten Carbide Tips for Tunnel Boring MachinesProduct Application: Shield Tunneling MachinesApplication Industry: Tunnel EngineeringProduct Description:A tunnel boring machine, commonly known as a shield tunneling machine, is specialized equipment designed for tunnel excavation. This modern marvel integrates optics, mechanics, electronics, hydraulics, sensors, and information technology. It performs various functions such as excavating and cutting through soil, conveying excavated material, assembling tunnel linings, and measuring guidance corrections. The machine encompasses expertise from geology, civil engineering, mechanics, machinery, hydraulics, electrical engineering, control systems, and measurement technologies. Tailoring the design and manufacturing process to different geological conditions is crucial, demanding high reliability. Tunnel boring machines are extensively used in tunnel engineering projects such as subways, railways, highways, municipal infrastructure, and hydropower.Functionality of the Tunnel Boring Machine Cutter Head:The cutter head of a tunnel boring machine is the front working component responsible for excavation. It consists of a cutting disc with multiple feeding slots, where tungsten carbide cutter heads are installed for cutting through soil. Typically, a set of cutter heads loads 30-40 or more alloy cutter heads for efficient operation. The specific quantity depends on the usage requirements of the tunnel boring machine equipment. Depending on the soft or hard nature of the soil being cut, hard rock tungsten carbide tools or soft soil tungsten carbide tools can be selected. All types of alloy cutter tools are connected by bolts and can be replaced from the soil chamber behind the cutter head.Advantages of Tungsten Carbide:Tungsten carbide, often referred to as the "teeth" of industry, is an excellent choice for wear-resistant tools. Tungsten carbide cutter tools for tunnel boring excel in complex environments during underground excavation where geological compositions are uncertain, such as in tunnel and subway construction. These tools are used in high-power equipment that exerts significant thrust and shear forces. The requirements for the alloy include excellent impact toughness and wear resistance. The dimensions of this tungsten carbide shield cutter head are Φ18Φ16R5*30.

Sanxin delivering carbide value. Main Products:(Manufacturing high precision cemented carbide parts) 1Drill Bits and Cutting Tools:carbide is widely used in drill bits and cutting tools for petroleum exploration and drilling, including rock drill bits and three-cone bits. Its high hardness and wear resistance make it perform well in geological exploration and underground drilling.2Oil Well Components:hard metal is crucial in manufacturing components for oil wells, such as pump parts, valves, and seals. These components require high wear 3Pipeline Cutting Tools:In pipeline maintenance and repair within the petroleum industry, tungsten carbide is used to manufacture cutting tools for cutting and repairing pipelines.4Oil Extraction Tools: Tungsten steel alloy finds applications in oil extraction tools, including parts for lifting pumps and submersible pumps. These tools need to have high strength and wear resistance to withstand high loads and harsh environments.5Petroleum Pipeline Repair Tools:Tungsten carbide is used in the manufacturing of tools for repairing and maintaining petroleum pipelines, ensuring durability and effectiveness.6Geological Exploration Tools: In geological exploration, wolfram carbide is commonly used in the production of tools such as core drill bits and drilling equipment to obtain samples from underground rock formations. Our AdvantagesAdvantages:Cemented carbide wearing parts, also called wolfram carbide (WC) parts, are a commonly used high-end ring in the hardware machinery industry, because of its high hardness, good toughness, superior high and low temperature wear resistance, small adhesion, good corrosion resistance, high thermal conductivity, less friction coefficient, and acid and alkali corrosion resistance does not rust, easy maintenance and other characteristics.With its good toughness, high temperature resistance and high wear resistance, the service life is 10~50 times longer than the general metal parts.Features:100% virgin cemented carbide materials;Fine-grain tungsten carbide;Excellent wear, abrasion, corrosion resistance;High fracture strength and high hardness;Longer service life;Varied grades;Competitive EXW factory price;Customization service.
