Design features

CNC system SiX

The system has been developed independently by Salvagnini experts, such enabling maximum use of the equipment. The intuitive interface allows graphic simulation of the part, setting up the machine tool, assigning the necessary parameters of bending and starting the machine all in a matter of minutes.

The CNC system includes: intuitive and fast touch screen programming, a task manager, an interactive online manual and full compatibility with any other equipment from Salvagnini.

Rigid frame

The press brake has a completely closed frame both in its top and bottom what adds strength and stability to the structure and keeps reference stops position constant.

Speed and precision

Thanks to the implemented direct drive technology, the Salvagnini company has launched the world's first press brake providing movements of the top-beam that can reach a speed of 250 mm/s. The innovative technology ofdirect drive transmission also provides:

  • Traverse positioning precision up to ± 0.002 mm
  • Significantly longer useful life of pumps and hydraulic motors.
  • Quiet operation of the machine.
  • Reduced power consumption.
  • The minimum amount of oil for the operation of the hydraulic system (100 l in total for a press with a force of 220 tons).


The frame deformation compensation system and the automatic mechanical crowning system Wila guarantee high precision bending and the same angle along the entire length of bending. This eliminates flaws and problems during the assembly of the final product.

Energy recovery for later reuse

The Kinetic Energy Recovery System (KERS) recovers energy that is usually wasted and reuses it later, in further stages of production, obtaining higher speeds and accelerations with the same energy consumption. It allows saving up to 70% of the usual energy consumption.

The part positioning precision is provided by well-thought rigid back gauges. Depending on how it is equipped, the machine can have from 4 to 12 controlled axes (including  Y1 and Y2) that allows handling parts of a complex geometry or arrange several workstations on a single machine.

Power consumption

The absence of proportional valves, together with the use of direct-drive transmission and brushless motorization, ensures that energy consumption is proportionate to the real intensity of use and utilization (that is, the machine does not consume when it does not perform); which turns the B3 press brake into a bending machine with extremely high performance ratio while keeping consumption and power levels low. Likewise, the KERS technology recovers energy and allows it to be reused later.

Unlimited automation

The unit can be integrated in a production line or a flexible bending cell with a robot or a panel bender.
