Underground tunnel construction is an extremely complex and dangerous project that requires various challenges and difficulties. In the whole process of tunnel construction, excavation is a very important link. The emergence of TBM (Tunnel Boring Machine) has brought revolutionary changes to tunnel construction. In TBM, the cutter is a vital component.

The TBM disc cutter, also known as the cutter head, is one of the most important components of the TBM. The TBM cutter is a machine that uses disc-shaped saws to cut the surrounding rock and excavate the rock layer by layer in order to excavate the tunnel. Due to the efficient and controllable design of the TBM cutter, it can significantly increase the cutting speed of the tunnel. This is a very important advantage in terms of construction schedule and quality.

There are many types of TBM cutters, of which the Disc Cutter is a common type. Its design combines cutting and cornering so it is suitable for many difficult-to-cut rock types. Disc Cutter consists of cutter head and body. During construction, the disc-shaped cutter head needs to rotate and exert some pressure on the rock to cut and excavate the tunnel.

Overall, TBM cutters are an integral part of the tunneling process. The use of TBM cutters not only improves the speed and quality of tunnel construction, but also makes the construction process safer and more controllable, becoming an important key technology in tunnel construction.
