TBM (Tunnel Boring Machine) Cutter Ring is a key component of tunnel boring machines. It is the cutting face of the machine, and its performance directly affects the tunneling efficiency and quality. The cutter ring consists of a series of cutting teeth and a body. It is the part that is in contact with the surface to be cut and its cutting force is used to cut the rock.

The TBM cutter ring is made of high-strength alloy steel, and its cutting teeth are made of high-strength cemented carbide. It has a high hardness and wear resistance, which ensures that it can effectively cut the rock. It is designed with a large number of cutting teeth, which can increase the cutting force and reduce the cutting resistance, thus improving the cutting efficiency.

In addition, the TBM cutter ring also has a strong shock resistance, which can reduce the impact of the rock on the cutter ring during the cutting process, thus reducing the wear of the cutter ring. The cutter ring also has a good self-sharpening property, which can ensure that the cutting teeth can maintain a high sharpness during the cutting process, thereby improving the cutting efficiency.

The TBM Cutter Ring is an important part of tunnel boring machines.
