Machining bearing supports for TBMs – Tunnel Boring Machines

Galbiati Group collaborates with leading tunnel boring machine manufacturers with regard to the supply and machining of components for TBMs (planetary gears, bearing supports, erectors etc.).

Below is an example of machining equipment for bearing supports (Cutterhead) for tunnel boring machines.

The Cutterhead support, represented below, was built by Galbiati Group, and was intended for a boring machine built for an excavation pilot project in Australia, Queensland. The TBM in question, shall have an overall diameter of 8 meters, and will be commissioned for digging two tunnels providing access to a coal mine.

Here are some photos showing the work phases of the cutterhead supports.
