Product Description
We are professional TBM shield driving cutter Rings/tunnel disc Disks cutter surface overlaying welding tungsten carbide Cutter Cutting rings from china
Our cutter rings are produced from standard steel, heavy duty steel and H13 tool steel with standard profile or hard faced profile in different hardness to accommodate various geological conditions such as sandstone, conglomerates, limestone, marble, quartzite, basalt, diorite and granite.
They are apply to the sand limestone, dolomite, kimestone, condensate, such as granite from soft rock to hard rock, all rocks. And they are suitable for Herrenknecht, Mitsubishi, Wirth, Komatsu, Robbins tunnel boring machines, we also can produce according to customers drawings or samples
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 .
Its cutter rings material could be choosed according to tunnel working condition
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.
The cutter rings are manufactured with ideal profile and tip width, usually 13mm to 25mm depending on ground conditions, in order to achieve high excavating efficiency and long lifetime.
Our TBM cutter rings can be interchanged completely with Herrenknecht, Palmieri, Robbins, and Wirth cutter rings.
