  • Category Rolling- Machines
  • Type Rooling Machine


Planetary driven rolls, with parallelism control by massive torsion bars. Forged steel, induction tempered and hardened. No maintenance needed. All machine parts are of the best quality, made in Italy.

All the MG machines can be equipped with CNC Touch Command EVO control, to help ensure accurate automatic bending. It is developed on a real-time Linux platform, generated following the machine geometry. The closed-loop system has an ongoing dialogue between the CNC and onboard machine sensors. The CNC reads the values and (if necessary) corrects them immediately, allowing for total control and no material waste. Our EVO control system adapts to different materials, and the operator can choose the required shape via simple input of base parameters. It controls accessories such as central and side supports, motorized tables, squaring arms, and loading systems. Our new G line can be equipped with remote assistance. 


TECHNICAL FEATURES. Automatic simultaneous balancing: bending rolls parallelism controlled by massive TORSION BARS working in symbiosis with sofisticated valves controlling the oil flow. This system grants the complete and steady parallelism without resetting. Planetary movements: bending rolls planetary movement that reduces frictions (common on traditional plate rollers) such as diagonal or horizontal sliding guides. Our components are pre-lubricated and sealed in a system granting lubrication for the whole machine life. Direct drive: replacing many low efficiency components (gears, bushings, transmission belts, sliding guides) with very efficient epicycloidal gearboxes DIRECTLY COUPLED on the rolls, bearings and hydraulic motors. MG plate rolling machine power is focused on the material to bend (positive strenght) with consequent Energy saving. Our system conforms to the International high efficiency and anti-pollution standards.

PERFORMANCE: Every MG 3-roll plate bending machine is driven by three hydraulic motors, directly assembled to the rolls by heavy-duty planetary gearboxes that grant maximum performance with the minimum possible strenght. The motion, given by the hydraulic pump powered by an electric motor, is directly transmitted to the gearboxes and to the rolls. All the three rolls are motorized in order to get a perfect sliding of the plate. This is very important during the pre-bending phase, to position the plate at the centre of the rolls with the maximum precision, without losing it during the working cycle. With MG you get a pre-bending that will never be bigger than 1,5  times the material thickness.

ROLLS CAMBERING. A great advantage of MG technology is the application on rolls of a variable cambering on the basis of material thickness. Each MG machine is different from the others even among same models because the rolls do not have the same cambering. During the bending work a particular phenomenon takes place, a problem that is not always visible: the rolls get subject to deflection. But thanks to the cambering, in our machines they do not reach the breaking point, and grant the perfect result in their bending performance.

PERMANENT LUBRICATION. MG can grant a permanent lubrication system by using autolubricated bearings. It’s enough only to grease the parts during the assembling. MG plate bending machines maintenance is never a problem, only a periodical refilling of oil will be necessary.

Planetary movement bending rolls - Rolls mounted on rods that turn on pre-lubricating bearings – No friction and less installed power – Parallelism control by massive torsion bars (no problem due to electro-hydraulic controls) – Tilting the rolls for conical working, and coming back to the initial position, is fast and easy.    

MG planetary system
The planetary movement of the bending rolls designed by MG allow our machines to bend diameters below 1.1 times the top roll diameter. On large diameters, we assure performances up to 30% higher than our direct competitors.

MG plate rolling machines can work many years without maintenance, thanks to the well-known strength of our hydraulic systems. Special manual distributors and valves allow us to have infinite variable speeds on all movements.
