The cutter head serves as the core working component of shield machines and pipe jacking machines, playing an irreplaceable role in the tunnel construction process. Its primary function is to directly interact with the stratum—whether it is hard rock, soft soil, or complex mixed strata—the cutter head bears the key tasks of cutting, crushing, and excavating the surrounding rock and soil.
Given its critical position in the equipment system, the design and manufacturing of the cutter head are closely tied to the overall performance of shield machines and pipe jacking machines. A scientifically optimized cutter head design, for instance, can enhance cutting efficiency by matching the stratum characteristics (such as adjusting the arrangement of disc cutters and pre-cutting bits), reduce energy consumption during operation, and extend the service life of cutting tools. Meanwhile, high-precision manufacturing processes ensure the structural stability and wear resistance of the cutter head, preventing issues like deformation or component failure that may cause construction delays. In summary, the quality of the cutter head directly determines the construction speed, project safety, and operational cost of tunnel boring equipment, making it a core focus in the research, development, and production of such machinery.
