Salvagnini S1.40

Four-metre sheet is the reason to pick the Salvagnini S1.40 over its shorter sibling. Its maximum sheet is 4,064 x 1,524 mm (160.0 x 60.0 in); the S1.30 stops at 3,048 x 1,524 mm. The rest of the table does not change between the two.

Long sheet changes how a punch-laser combi earns its keep. More parts fit in a nest before the machine has to stop for a new blank, and long parts such as cabinet sides or door skins come off in one piece. Salvagnini lists three production strategies for the automated cell: single parts; multiple parts and nests, microjointed or separated, with the scrap preserved and the skeleton unloaded; and separated nests with the skeleton destroyed. On a sheet this long the choice affects what unloading device is needed, so decide it before the layout is drawn.

The tooling concept is a multi-press head with a die structure for up to 59 tools, individually actuated. The thick turret tools are designed and produced by Matrix, a company in the Salvagnini Group. A fiber laser of 3000-4000 W, cutting with nitrogen or compressed air, separates the parts and handles irregular contours.

Capacity is deliberately narrow. Aluminum, steel and stainless steel are all listed at 5.0 mm (0.20 in) maximum for both punching and laser cutting, with a 0.5 mm (0.02 in) minimum. The smallest sheet the manipulator accepts is 670 x 400 mm (26.4 x 15.7 in). The drive that moves the tools uses a controlled descent, which Salvagnini says reduces cycle times and improves punching quality.
