Shield & TBM cutter for underground tunnelling
Description:
A tunnel boring machine (TBM) is a machine used to excavate tunnels with a circular cross section
through a variety of soil and rock strata. There have a very big circle blade in the front of tunnel
boring machineequipped with various kinds of cutters, in order to promote stable and longer lasting
life of application, we have research and developed special tungsten carbide materials suited to your
application.The TBM technology is mainly used in underground ming and traffic tunnelling like metro,
railway and road tunneling.
