Tci Disc Cutter For Tbm
Posted at: Offers to Sell and Export | Posted on: Friday 4 December 2009 8:13 am | Poster last visit: Friday 4 December 2009 |
Product Description:
applied to bore in hard rock or mixed ground; break rock into chips, rather than crushing it into fines
or ripping it from the face. The rotating disc cutters create “crush zones” through which fractures propagate. Chips are then broken away from the face. This action makes single disc cutters excellent in solid rock. Ground conditions determine cutters selection and characters, such as ring material, ring hardness, hub hardness, ring profile and width, cutters starting torque, seal and so on.
Cutter ring is made from alloy tool steel and specially heat-treated to reach proper balance of hardness (HRC55-59) and toughness. Tungsten carbide tips will be inserted in ring if cutters are applied in very abrasive ground. To improve boring efficiency, ring is made into different profiles and width for different ground conditions
cutters starting torque is adjusted to proper level (25-50N.m) by preloading in order to rotate freely and prevent them becoming blocked
metal floating seal and anti-dust seal are mounted in cutters. If necessary, the pressure compensated piston will be mounted in shaft, so Lubrication oil will not leak and sand will not permeate, in this way cutters bearing has long lifetime
