Jun 05, 2014 Disc cutters fitted with tungsten carbide bit inserts are the norm in the mining and exploration drilling industries but although their crossover into the civil tunnelling industry for application on TBM cutterheads has been trialed, it remains elusive. The practice is now mounting a potential comeback with recent applications on EPBMs in different geologies and in different parts of the world

All About Tunnel Boring Machine (TBM) & Parameters

May 12, 2016 The TBM clock is activated by some minimum level of propel pressure and/or by a minimum torque and the start of cutter head rotation. This operating time is used to calculate the penetration rate (PR), as a measure of the cutter head advance per unit mining time.

Penetration, cutter wear and rate of advance for TBM

- Maximum permissible/available disk cutter cutting thrust Minimum necessary cutting thrust per disk cutter Maximum conveying rate of the TBM conveyor. The optimization of tunnelling accomplished in practice by machine operators by means of continuous balancing of cutting thrust and speed must also be incorporated into the calculation.

Tunnel boring machine Wikipedia

A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.They can be designed to bore through anything from hard rock to sand.Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.

Design Optimization of TBM Disc Cutters for Different

A novel optimization methodology for the disc cutter designs of tunnel boring machines (TBM) was presented. To fully understand the characteristics and performance of TBM cutters, a comprehensive list of performance parameters were investigated, including maximum equivalent stress and strain, specific energy and wear life which were closely related to the cutting forces and profile geometry of

Gripper TBM Herrenknecht AG

When tunnelling with a Gripper TBM, a rotating cutterhead equipped with disc cutters is pressed against the tunnel face with a pressure of up to 32 tonnes per disc. Due to the rolling movement of the cutter, single pieces so- called chips are broken out of the rock. Water jets can cool the cutting tools and reduce dust formation.
