MG G Series Hydraulic 3-Roll Plate Bending Rolls
The line of 3 roll bending machines is reliable and tested, with three driving rollers with hydraulic double pinching that guarantee a precise and constant drag of the material. Easy to use and accurate in executing shell rings, it boasts a unique versatility thanks to the exclusive MG planetary geometry.
The parallelism of the side rolls is controlled by a torsion bar system that connects both sides’ ends, eliminating the disadvantage of delicate and unreliable encoders. The rolls are driven by hydraulic motors and high-efficiency planetary gearboxes, coupled directly on the rolls. The MG solution reduces the dispersions of the applied force generated by the various components’ frictions.
