Manufacturer profiles with relevant production capability in China
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Not customer reviews or live demand data. These dimensions support RFQ preparation and supplier evaluation.
These scores are example evaluation dimensions, not real customer ratings, country-specific buyer feedback, or live inquiry activity.
Our cutterheads are constructed from high-strength steel and abrasion-resistant steel alloys, with critical wear surfaces protected by hard-facing materials like tungsten carbide for extended service life in demanding excavation conditions.
A complete cutterhead assembly includes the main structure/body, disc cutters for primary excavation, muck openings/ports for material removal, scraper picks/rippers for secondary cutting, and wear protectors to shield vulnerable areas from abrasion.
As the rotating front assembly of a TBM, the cutterhead excavates soil and rock through direct contact. Its rotating motion drives disc cutters and rippers into the tunnel face while muck openings allow excavated material to pass into the machine's conveyance system.
