Description
The main product materials are: die steel H13ESR, DC53 is suitable for hard rock disc cutters of tunnel shield machines, LD is used; cold work die steel Cr12, Cr12Mov, Cr12Mo1V, Cr12Mo1V1 is suitable for cold punching, extrusion, and rolling molds Etc.; stainless iron 1-4Cr13 is suitable for valves, plastic molds, etc.
TBM disc cutter is a disc-shaped roller cutter mounted on the cutterhead of tunnel boring machine, which is an excavation tool for breaking hard rocks. The type of disc cutters, in different sizes and specifications, can be mounted on the cutter heads of large trenchless construction equipment such as TBMs, shield machines, MTBMs, pipe jacking machines, shaft boring extension machines, and are widely used in subway tunnels, railway tunnels, diversion tunnels, urban underground pipe network construction, mining and other industries.
