Professional TBM Shield Cutter Bits for Tunnel Excavation

These shield cutters are designed for consistent penetration and reliability in diverse geological environments. By integrating tungsten carbide with alloy structural steel, we offer a tooling solution that balances wear resistance with impact toughness.

Key Features & Benefits

• Composite Material Construction: Each cutter utilizes a tungsten carbide tip for rock-breaking capability and a reinforced steel body for structural integrity.

• Enhanced Wear Resistance: The alloy head is formulated to withstand abrasive environments, supporting extended service intervals between tool changes.

• Effective Impact Absorption: The alloy steel body is treated to absorb shock loads, maintaining tool stability when encountering varying geological layers.

• Advanced Bonding Technology: Our specialized brazing process ensures a secure bond between the alloy head and the steel body, providing reliability during high-torque operations.

• Precision Engineering: Manufactured to tight tolerances to ensure a consistent fit on standard TBM and shield machine assemblies.

III. Product Attributes

1. Material Composition: Utilizes YG Series Tungsten Carbide for the cutting tip and 42CrMo Alloy Steel for the body to balance hardness and structural resilience.

2. Joining Process: Employs Vacuum Brazing Technology to ensure a stable and reliable bond between the carbide insert and the steel housing.

3. Specific Hardness: The carbide head maintains a hardness range of HRA 88-92, while the steel body is heat-treated to provide high tensile strength.

4. Mounting Compatibility: Designed with Precision Threaded Holes to ensure compatibility with major shield machine brands and international standard mounts.

FAQ:

P1: Da li ste fabrika ili trgovačka kompanija?
Mi smo tvornica sa 12 godina iskustva u proizvodnji.

P2: Gdje se nalazi vaša fabrika?
Nalazimo se u gradu Zhuzhou, provincija Hunan, gdje je baza od volfram karbida.

P3: Da li je cijena konkurentna?
Imamo sopstvenu fabriku. Zahvaljujući snažnom sistemu proizvodnje i distribucije, obećavamo da ćemo našim kupcima ponuditi najkonkurentniju cijenu.

P4: Da li su proizvodi visokog kvaliteta?
Da. Svi proizvodi će biti testirani prije masovne proizvodnje, a mi ćemo provjeriti fizička svojstva, oblik i toleranciju kako bismo osigurali kvalitetne proizvode prije isporuke.
