The carbide shield cutter plays the role of cutting and excavation during the tunneling process of the shield machine. There are generally hundreds of carbide shield cutting knives distributed on the front-end cutterhead of a shield boring machine. These knives continuously cut and break soil and rocks during the excavation process. The high hardness and high wear resistance of the carbide shield cutter enable it to perform cutting and excavation operations efficiently while reducing wear on the shield machine.
The shield machine needs to deal with different geological conditions during the excavation process, such as soft soil, sand, rock, etc. Under different geological conditions, carbide shield cutting tools can give full play to their cutting and excavation advantages and help the shield machine advance smoothly.
In addition, the support and stability of the carbide shield cutter also help improve the construction quality and efficiency of the tunnel. By providing better support and stability, carbide shield cutters can help the shield machine maintain a straight trajectory and reduce deflection and vibration, thereby reducing the risk of damage to the shield machine.
In short, the carbide shield cutter plays an important role in the tunneling process of the shield machine. Its cutting and excavation capabilities, support and stability are all key factors for the efficient tunneling of the shield machine.
