Cutter Box

Product Highlights

The Cutter Box is a key structural component of the shield cutting system, supporting disc cutters or scrapers and directly connecting the cutting tools to the cutterhead. Its structural reliability is critical to cutting stability and overall cutterhead safety.

Designed based on long-term field experience, Xinda Cutter Boxs are optimized for high-load transmission, impact resistance, and mounting stability, ensuring correct load paths and stable tool operation under complex ground conditions.

Performance Advantages

High-strength structural design, stable load capacity

Manufactured from high-strength steel with reinforced load-concentration areas, the Cutter Box reliably withstands impact loads and alternating stresses generated during rock breaking and scraping.

High dimensional accuracy, clear load transmission

Precisely machined mounting and mating surfaces ensure stable load paths between the cutting tools and cutterhead, reducing abnormal wear and structural fatigue caused by misalignment.

Strong resistance to deformation, suitable for complex conditions

Under hard rock, mixed ground, and eccentric loading, the housing maintains structural rigidity without plastic deformation, extending the service life of both the cutting tools and the cutterhead system.

Application

Xinda Cutter Boxs can be custom-designed according to different shield machine types, cutterhead structures, and tool layouts, suitable for EPB shields, slurry shields, and related TBM systems.
Applicable to new machine assembly as well as maintenance, replacement, and structural upgrades of in-service equipment.
