Ottotech DAVI MCB 4-Roll Plate Bending Machine - Precision Bending with Superior Control

The MCB 4 roll machine is the most suitable hydraulic plate roll for metal thickness of between 12 mm to 100 mm.
The bottom pinching roll gives the maximum control of the plate inside the roller and reduces the green compared to the standard 3 rolls plate roll.

The side rolls, driven by the unique DAVI planetary guide technology, provides the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy due to the perfect parallelism offered by the patented Servo-Tronic© system.

The frame constitutes, effectively, the backbone of the machine. The stress generated during plate forming must be withstood by this critical component and eventually, transmitted to the foundations. DAVI machines feature the most compact and closed frame on the market, which enables you to improve the rigidity of connection to the ground as well as machine stability, minimise deflections and displacement for the maximum, positioning accuracy of the rolls.

With the standard motorised top and bottom rolls and unlike other solutions available in the market, it offers bolted-rigid coupling of the gearbox structure to the machine frame, the DAVI exclusive pendular arrangement allows for swingable connection between the motor gearboxes and the frame. The DAVI pendular shaft-mounted gearbox configuration allows for stress-free tilting of the rolls up to 100 mm (4”) every 3 metres (10 feet) of roll length. The pendular gearbox arrangement allows for free deflection of all the rolls under the load, with limited stress on shaft-hub connection, maximising the bearings reliability and durability and a much higher tilting capacity for cone-forming.
