Boring Dia: 95 – 700mm,Boring Stroke: 900mm
- Quick set adjustable clamping jaws
- Swivel toolpost for grooves and bevels
- Continuous groove geared facing and boring feeds
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.

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