Salvagnini S4-40

With a maximum sheet of 4,064 x 1,650 mm (160.0 x 65.0 in) and a diagonal of 4,655 mm (183.3 in), the Salvagnini S4-40 is the long version of the S4 punching-shearing center. The S4-30 takes 3,048 x 1,650 mm. Speeds, accelerations and thickness limits are the same on both.

What a four-metre S4 is for is flow. The machine takes a sheet, punches and forms it, shears the parts free and sends them on, with no semi-finished stack between operations. Salvagnini describes it as easy to configure for stand-alone work, in-line use, a flexible cell or lights-out manufacturing. Feeding can come from the PD automatic pack destacker, the MD store for single sheets or the MV store for packs; the IA table stacker and the MCU Cartesian manipulator handle what comes out.

Tooling stays loaded. The multi-press head houses up to 117 thick turret tools across stations B, C and D, each actuated individually, and all of them carry a 9 mm sharpening margin. Lower cylinders can be mounted, and station D accepts Multitool forming tools. If threads are needed, an optional electrical tapping unit for up to 6 different tools mounts beside the head, outside it, so it takes no tool positions.

Check the thickness table against the material mix before ordering. Aluminum is listed at 5.0 mm (0.20 in) for both punching and shearing. Steel punches to 4.0 mm (0.16 in) but shears to 3.5 mm (0.14 in), and stainless steel punches to 4.0 mm but shears to 2.0 mm (0.08 in). The punching figures are given without multitool. The manipulator will not take a sheet smaller than 600 x 400 mm (23.6 x 15.7 in).
