The Current State of Disc Cutter Design and

2017-5-31  ABSTRACT: Rolling disc cutters are the business end of hard rock and mixed face tunnel boring machines(TBMs). Since their first successful employment on a TBM over fifty years ago, disc cutter technology hasconstantly evolved, allowing modern TBMs to excavate very hard and abrasive rock efficiently. Disc cuttershave also been employed successfully on earth pressure balance (EPB) and slurry machines, cutting rockunder water and ground pressure. The range of materials excavated by machines today is broader, excavationrates higher and cutter costs lower than ever before, proving the value of investment in cutter development. This paper describes recent improvements in disc cutter components including cutter ring materials andprocessing, as well as improvements in lubricants, bearings, seals and cutter condition monitoring. Thesedevelopments have resulted in more reliable cutters
