TBM cutter disc is a disc-shaped roller cutter mounted on the cutterhead of tunnel boring machine, which is an excavation tool for breaking hard rocks. The disc cutters can be mounted on the cutter heads of large trenchless construction equipment such as shield machines, TBMs, pipe jacking machines, shaft boring extension machines, and are widely used in subway tunnels, railway tunnels, diversion tunnels, urban underground pipe network construction, mining and other industries.

Litian has been conducting research on the materials, heat treatment process and manufacturing process of the TBM disc cutter components, combined with on-site testing to make improvements. As a result, the TBM disc cutters produced by Litian heavy industry has been in a leading position in the industry in terms of wear resistance, high temperature oxidation resistance, toughness. Litian TBM roller cutter can adapt to the needs of multiple types of engineering, and can meet the requirements of long-distance excavation under the compound strata of highly weathered rock, moderately weathered rock, slightly weathered rock, and has good stability and reliability.

TBM Disc Cutter Types And Components

Single Disc Cutter

Single disc cutter is usually mounted on the face area and gauge area of cutter head. It is mostly used to break mixed ground and hard rock with high uniaxial compressive strength.

Double Disc Cutter

Double disc cutter is usually mounted on the face area and gauge area of cutter head, and is mostly used to break mixed ground and rock with low uniaxial compressive strength.

Twin Disc Cutter

Twin disc cutter is mounted on the center area of TBM cutter head, and is mostly used to break mixed ground and hard rock.

Triple Disc Cutter

Triple disc cutter is mainly used on micro-tunneling equipment and can be mounted at any position on the cutter head as required.

Disc Cutter Ring

TBM disc cutter ring is an indispensable part of the rolling disc cutter, and it is the first component that comes into contact with the rock.
