TBM Tunneling Double Disc Cutter / 42CrMo Twin Boring Machine Cutter

TBM tunneling Twin Disc Cutter

Description

It could be devided into single disc cutter , double disc cutter , multiple disc cutter . Its outer cutter rings could be devided into standard cutter ring , wide disc cutter ring , heavy duty cutter ring , surface overlaying welding cutter ring , cutter ring with carbide button etc .

TBM cutter rings must be highly wear resistant and robust because they serve as the key excavation component.

Standard cutter rings are forged with alloy tool steel and heat-treated to HRC56-58 with an ideal balance between hardness and toughness, making them suitable for soft ground to mixed ground.

Heavy duty cutter rings are forged with alloy tool steel and particularly heat-treated to HRC57-59 with an ideal balance between hardness and toughness to avoid curling and fracturing, so they are suitable for hard rock and abrasive rock.

cutter rings are inserted with tungsten carbide tips and suitable for abrasive but not hard ground. The undulating nature of we would help the cutter to rotate in the low strength but abrasive rock, and avoid flat spotting.
