    Herber production tube bending machine for tubes with small bending radii, for tubes Ø 25–80 mm. The combination of pressure die booster and a direct-action programmable
    pressure unit at the end of the tube, the ”Centerline booster” makes extremely small radii possible, i.e 0,8 x the outside
    diameter of the tube. The equipment with free programmable tool change also makes automatic production of very complicated details without intermediate tempo changes possible, i. e manifolds of cars.


    Standard components from well-known european manufacturers.
    Pneumatics, hydraulics, electrics and mechanics according to VDMA, ISO and DIN-standards.
