TDG90 line boring has strong processing capacity Ø95 to 700mm due to enhanced mount kit support and high strength boring bar, which is mainly used in repairing bores, steel structure, hinge hole, steam turbine wheel connection hole, pump and valve.

Compact and modular design

Rotational drive unit and feed unit can be fixed anywhere of the boring bar to achieve processing in narrow space. More portable, step less speed regulation range 0 to 0.5mm, easily achieve the forward and reverse exchange.

Boring bar

High-quality alloy structural steel, several times heat treatment, high strength, boring bar’s length can be up to 8 meters.

Various type mount kit support

Double arms, three arms, four arms and center support can be selected.

Drive Power Unit

Two kinds of power system: servo and hydraulic, torque of hydraulic power unit can reach to 1420N.M, this machine can achieve cuts to a maximum depth of 10mm.

Superior scalability

  • Optional attachment of taper boring, to achieve processing of different taper holes 1:12 and 1:20.
  • Two sizes of facing head to achieve facing processing.

All parts have their own unique advantage and provides guarantee for steady and accurate operation for the whole system.
