High Hardness Tungsten Carbide Tips for Tunnel Boring Machines
Product Application: Shield Tunneling Machines
Application Industry: Tunnel Engineering
Product 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.
