Tungsten Carbide Shield square shank Teeth Cutter
Overview:
Tungsten Carbide Shield square shank Teeth Cutter 
Used on tunnel boring machine and suitable for soft rock fomation.


The front cutter
Ploughing the soil before any other cutters of tunnel boring machine, this will remarkably increase the liquidity of soil, reduce the torque of the cutters, and raise cutting effiecncy.
Tunnel Boring Machine, engineering machinery for tunneling. It has been widely used in subway, railway, highway as well as municipal engineering' tunneling work.
Tunneling cutters are assembled on the tunneling borer machines for tunneling work. The main cutters are hob and scraper. The hob is mostly made of steel material for rock breaking. The scraper is usually made by tungsten carbide bits brazed on the steel body for scarping the earth and silt. Shield alloy is the carbide cutters on TBM for tunneling work. Usually tungsten cobalt alloy is used as material for the carbide bits, which requires the alloy has high hardness, wear resistance and impact toughness. The structure and composition of alloy has high hardness, wear resistance and impact toughness. The structure and composition of alloy are different according to the difference of the tool's functioning stratum.
