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 machine 

equipped 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.
