Development and Performance Evaluation of an Integrated Disc Cutter System for TBMs
Changing the cutter is an essential procedure in tunnel boring machine (TBM) operations. The danger and low efficiency of manually replacing the disc cutter has led engineering equipment designers to study technologies to automate the changing of cutters.
