TBM Cutterhead Technology: The Heart of Excavation

TBM Cutterhead: The Spearhead of Tunneling Performance

The efficiency of any Tunnel Boring Machine (TBM) is ultimately determined by the performance of its cutterhead. As the primary point of contact with the ground, the TBM Cutterhead must be robust, properly configured, and easy to maintain. Our custom-designed TBM Cutterheads ensure optimal excavation rates and reduced downtime.

The Anatomy of a Cutterhead

A cutterhead is more than just a rotating steel disc. It is a complex assembly of cutting tools tailored to the geology:

Disc Cutters: Heavy-duty steel rings used to fracture hard rock through high contact pressure. Scrapers/Rippers: Tools designed to scoop away soft soil and clay in EPB and Slurry TBMs. Buckets: Openings that channel the excavated muck into the machine's conveyor system.

Custom Designs for Unique Geology

One size does not fit all. We analyze the geological survey data to design the perfect cutterhead:

Hard Rock Heads: Flat or slightly doomed profiles with high-density disc cutters. Soft Ground Heads: Spoke-type designs with large open areas to prevent clogging (clogging) in sticky clay. Mixed Ground Heads: Hybrid designs capable of handling abrupt changes from soil to rock.

Maintenance and Safety

Replacing cutting tools in high-pressure environments is dangerous. Our TBM Cutterheads feature back-loading systems and wear detection sensors, allowing for safer and faster tool changes, minimizing the time workers spend in the excavation chamber.
