DR pneumatic straightening press

DUNKES has a custom solution for the entire range of straightening technologies from round, flat, to profile materials.

Regardless of whether this involves straightening of simple round parts, or complex profiles that also need to be torsion straightened. Standard straightening presses are supplied as joystick-controlled, semi-or fully automatic plants. DUNKES straightening technology facilitates a significant improvement in the increased quality expectations with respect to run-out accuracy, straightness and torsion.

The plans are configured in accordance with ergonomic considerations, therefore representing improved work methods and forward-looking solutions. A servo control for the ram axis is used for larger straightening forces, in combination with a joystick control due to the improved handling and ergonomics. Precise positioning accuracies are attained due to the servo orientation control.
