Cutters and tubes for Large DIA-Slurry Balanced TBM

The original design of cutter installation method for large diameter slurry balanced TBM is back loaded single tube with two single cutters. According to our track and service for several projects, this type of cutter tube and cutters with retainers have many shortages.

The mounting surfaces on cutter holders are easy to be crushed after being used several times, due to which the cutters will not be steadily mounted.

The mounting surfaces of the cutter retainer are easy to be crushed, and looseness as well as vibration will be caused.

Our front-loading disc cutter and cutter Tube have been redesigned and optimized creatively by EAST in the past 4 years, and the cutter’s stability has been successfully increased greatly.?
