electric press brake / CNC / automatic

In concept this kind of press brakes applies the principle of an electrical hoist with pulleys connected in series which move the tool holder (top beam) through high resistance drive belts (see diagram below).

According to the motor power and to the number of belt gears our machines have a working force much higher than that of traditional electric press brakes with ball screw or roller bearings.

The placing of several idle pulleys along the length of tool holder, guarantees a total absence of deflections in the central part also if machine is subject to overloads.

This, however, does not apply for the lower beam which, resting on the extremities, could be subject to deflections in case of overload bending.

g.a.d.e. wanted to move a step forward and in order to guarantee to its customers max. bending precision, has designed the first electrical press brake with ACTIVE hydraulic crowning and highly efficient energy saving system.

To achieve this, the motor of the hydraulic group, managed by the CNC, is activated only for the time crowning is required.

Among the peculiarities that make g.a.d.e. electric press brake extremely versatile and efficient there are noiseless performance and use of slides made of high-tech material, lubrication-free even over long working periods.

Moreover, the high acceleration given by the press brake electrical control allows a drastic reduction of the bending cycle for two main reasons:

- Approaching stroke made ENTIRELY at maximum descent speed;
- No machine stop at speed change point is required.

The features above together with an innovative and original design make Italian quality once more unique and here enhanced by g.a.d.e
