Tungsten Carbide Inserts for Shield Tunneling Boring Machine Head
Shield Tunneling Machine Head Carbide Buttons

Tungsten Carbide inserts, carbide buttons, are experts for tough hard rock.
They are assembled for shield tunneling boring machine head.
Generally, a group of shield machine head loaded 30-40 units or more for operation based on the use of shield mechanical equipment.
And, tungsten carbide inserts are bolted and can be replaced from the soil backroom behind the machine head.

As industrial teeth, is a good choice for wear resistant tools. It has complex application environment, engaged in underground tunneling, used in tunnel, subway and other projects with unclear geological components, and high-power equipment such as propulsion force and shear force, which requires the tungsten carbide inserts to have good impact resistance and wear resistance.
The size specification is: φ18*φ16*r5*30
Or, to be customized by your carbide buttons, inserts, tips, or roof bits drawings.

Key Points:

Mainly Usage:
Tunneling Boring Machine, in short, TBM is the ideal machine for tunnelling in hard rock, like building subway, railway, highway, municipal, hydropower and other tunnel projects.
And according to different geology of the "tailored" type of design and manufacturing, the reliability requirements are extremely high.
Applications:
Polyconic, Parabolic and Mushroom Tungsten carbide buttons, are the general buttons shapes for coal mining series.
Suitable for welding coal mining, coal mining machine in mid-soft rock formation, tunnel excavation in hard rock formation, drilling on extra hard rock formation or tunnel excavation in complicated rock formation.
