TBM/Shield Cutting Ring

1. Product Advantage:

XTC TBM and Pipe Jacking Cutting Rings are engineered for extreme geological conditions, delivering unmatched durability and efficiency in high-impact environments. Leveraging advanced gradient heat treatment technology, our cutting rings feature a hard, wear-resistant outer surface paired with a tougher, ductile inner core—a design that doubles impact resistance compared to conventional products.

These cutting rings maintain peak performance even in complex, abrasive, or fractured ground conditions. Ideal for demanding tunneling projects, they ensure consistent penetration rates, reduced downtime, and extended service life—maximizing productivity and minimizing operational costs.

2. Product Model: 

XTC TBM and pipe jacking Cutters available in three grades—JLDQ001, JLDQ002, and JLDQ003—these rings are suitable for rock hardness ranging from 40MPa to 240MPa (See the table below), meeting the requirements of diverse working conditions. 

Carbide Button Inserted Cutting Ring:

Designed for moderately weathered composite formations, the high-performance carbide buttons ensure longer excavation distances, extended service life, and reduced replacement intervals, improving overall work efficiency of tunneling tools, especially XTC TBM cutter.
