TBM Cutter

Tunnel boring machine cutter, referred to as "TBM Cutters", are excavation
tools installed on the cutter heads of tunnel boring machines and shield
machines, which include TBM disc cutters (single disc cutter, double disc
cutter, twin disc cutter) and soft ground cutters (eg. scrapers, cutting
knives, buckets, rippers and other cutting tools). This type of disc cutters
and soft rock cutters can also be used on pipe jacking machines and other
similar equipment.

Litian has been focusing on the development of TBM roller cutters and
solutions suitable for various rock conditions, and we have made remarkable
achievements in helping users improve tunneling efficiency and reduce
overall costs with TBM cutting tools and spare parts. Litian has now
developed into the largest supplier of TBM disc cutters in China.
