Cutting Efficiency of a Single PDC Cutter on .

The shearing action induced by fixed cutters has shown to be more efficient for penetrating rock than the crushing effect of the teeth or inserts on the rolling cones of a roller bit (1-4). However, PDC bits have traditionally had limitations when encountering hard formations (5). Therefore, PDC bits are not yet preferred for hard formations ...

Large-Diameter 20-Inch Disc Cutters: A Comparison of Tool ...

Optimization of disc cutter life and penetration rate in hard rock can be one of the biggest predictors of project success. With hard rock TBMs being used today in ever more difficult conditions and longer tunnels, the question of which type of disc cutter to be used becomes critical. At one such project in Northeastern China, varying disc cutter tool steels and sizes were put to the test on a ...

cutters were small and looked little like modern hard rock disc cutters. Because the rock could be excavated with low cutter loads, the cutter bearings didn't need to be very large and the cutters were kept small which made them very easy to handle and change. How-ever, soon TBMs were forced into ever harder rocks, which resulted in an unacceptable rate of cutter wear on the small cutters ...

Home - Hard rock cutting technologies for mining

Mechanical Hard Rock Mining. Mechanisation of mining operations has been of interest for decades to improve productivity and reduce cost. However, in hard rock mining applications, this has been impeded by the limitations of the existing mechanical rock fragmentation capabilities, being constrained power, limited strength of mechanical components and short cutter life.

Recent cutter technology advances to efficiently bore ...

In very hard rock conditions where the cutters are pushed to their limit, it is common to see some destructive wear such as mushrooming and chipping along the edges of the cutter ring. This is not a significant problem until the destructive wear becomes the dominating wear mechanism for the cutters and/or the cutter wear getto a detrimental level. Historically the best s compromise between the ...

SUPER-HARD, THICK, SHAPED PDC CUTTERS FOR HARD ROCK ...

bits (Appl et.al, 1962) and PDC cutters (Langveld, 1992) showed that both cutters and bits should last much longer than had been observed in the field. The difficulty of obtaining long bit life in hard rock was discussed by Feenstra (1988) where temperature limitations and impact resistance of the PDC's were highlighted as areas for improvement.
