TDG90 line boring has strong working capacity from Ø95mm to 700mm , bar length can be reach to 8000mm, now, it is adopted by many mining machinery manufacturers for the workshop production of large steel structure…

Compact and modular design

Rotational drive unit and feed unit can be mounted anywhere of the boring bar , 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, high strength, boring bar’s length can be up to 8 meters.

Mounting kit

Four type mounting kit can be selected: double arms, three arms, ID mounting , adjustable ID mounting .

Drive Power Unit

Two kinds of power unit: servo and hydraulic, torque of hydraulic power unit can reach to 1420N.M.

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 machining.

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