Salvagnini S4-30

The Salvagnini S4-30 is a punching-shearing center for sheet up to 3,048 x 1,650 mm (120.0 x 65.0 in). Loading, punching, forming, separation and unloading run automatically in one system, and parts leave it cut to size by an integrated shear, not nibbled out or left in a skeleton.

Two components define it. The multi-press head has a die structure housing up to 117 thick turret tools in stations B, C and D, all available over the area of the largest sheet. Station D has a maximum force of 30 tons. Next to the head sits the shear: two 500 mm blades, independent and at right angles to each other, with blankholders, able to cut any length in X or Y, simultaneously or independently.

The manipulator moves the sheet at up to 132 m/min in X and 117 m/min in Y, or 176 m/min with both axes moving together. Acceleration is 30 m/s2 in X and 17 m/s2 in Y. Salvagnini says the manipulator adapts its dynamics to the size and weight of the sheet.

Punching and shearing do not share the same thickness limits, and the gap matters when a job is quoted. Punching reaches 5.0 mm (0.20 in) in aluminum and 4.0 mm (0.16 in) in steel and stainless steel, without multitool. Shearing reaches 5.0 mm in aluminum, 3.5 mm (0.14 in) in steel and only 2.0 mm (0.08 in) in stainless steel. A stainless part can therefore be punched at a thickness the shear cannot separate. Minimum thickness is 0.5 mm (0.02 in), and the smallest sheet is 600 x 400 mm (23.6 x 15.7 in). The S4-40 is the longer model.
