S4 - Punching-shearing center
Thanks to the multipress head, integrated shear, punch&cut and nests without holding scrap, the S4 punching-shearing center achieves the maximum precision, eliminates waste and obtains the highest efficiency.
A single structure with no stops for tool changes.
Patented by Salvagnini, the multi-press head consists of a die-structure in which the punching stations are fitted with all the tools needed for production.
No stopping is required for tool change nor are automatic set-up devices needed since the tools are always available.
Thanks to this feature, all the movements required to move the sheet to the active tool are eliminated. This function makes the S4Xe unbeatable in terms of both cycle time and tool life.
5 different multi-press head configurations.
Salvagnini offers 5 different multi-press head configurations, with different numbers of stations, to meet the diverse production needs of each and every customer.

- PUNCH & CUT
Eliminates waste and balances kit production.
The shear, one-of-a-kind on the market, adjacent to and integrated with the multi-press head to create a single structure, makes for an extremely compact, multi-function system, ensuring an extremely high degree of efficiency and performance. It consists of two 500 mm independent blades, orthogonally positioned, mobile and equipped with blankholder to permit cuts of any length along both the X and Y axes.
In traditional systems, individual parts making up a multiple sheet or nesting pattern are processed sequentially once the whole starting sheet has been punched. Salvagnini’s Punch&Cut function, on the other hand, recognizes the punchings belonging to each individual part, groups them together accordingly and processes them separately, thus balancing kit or multiple productions as generally required on FMS lines.
Mode of operation: no energy, time or scrap wasted
Automatically controls ramps and reduces cycle times.
The manipulator, patented by Salvagnini, slides on guides integral with the lower part of the "C" structure, for high positioning precision; it has a lightweight movable symmetrical device, with 9 pincers and 9 mechanical references, for perfect centering and outstanding process reliability.
The long 3030 mm stroke allows blanks up to 3024 mm to be processed without regripping, for excellent productivity and incomparable process accuracy.
A double motor for superior performance
The manipulator is equipped with two pairs of brushless motors: one pair uses proprietary hand-over kinematics while the second uses gantry control logic.
This solution guarantees the following advantages:
• it greatly increases manipulator dynamics and maximum speeds;
• It reduces cycle times, allowing greater machine productivity;
• it guarantees processing accuracy, thanks to the perfectly balanced thrust;
• it enhances dynamics, even when processing thick material, or on type 40 machines (that can process blanks 4 meters (157”) long);
• it maintains accuracy, even with very long manipulator strokes.
