Price estimate
We do not have a price for the Salvagnini B3 320/4250 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Salvagnini B3 320/4250 is a heavy electric press brake: 320 tons of bending force on a 4,250 mm (167.3 in) table. It belongs to the top frame size of the B3 range, recognisable in the table by a total height of 3,755 mm and a width of 2,085 mm.
At this force the machine moves from sheet into plate work. Chassis members, bucket and hopper sections, heavy brackets and thick stainless components are the sort of parts that need 320 tons over four metres. The deep window is standard, with a 520 mm throat, 450 mm maximum stroke and 700 mm table-ram distance, and the side frames stand 3,600 mm apart.
What is unusual is that the ram figures do not fall with the tonnage. Approach and return are listed at 220 mm/s, the same as the B3 240/4250, and the drive is the same electric concept: two independent direct-drive brushless motors. Average consumption is 3.5 kWh.
The mass is 25,000 kg (55,115 lb) and total length 5,350 mm. Thick material means heavy blanks and more springback variation. The first is answered by the optional FLW sheet followers, at up to 150 kg each. The second is what the AMS laser angle measurement system is for.

Frequently Asked Questions
01
Maximum bending force is 320 tons on a table 4,250 mm (167.3 in) long. Salvagnini's range runs from 80 to 400 tons, so this is the second-highest force class; the B3 400/4250 is the next step on the same table.
02
Salvagnini presents the B3 as an electric press brake. Ram movements are driven by two independent direct-drive brushless motors. On this model approach and return speed is 220 mm/s and average consumption is listed at 3.5 kWh.
03
Total length 5,350 mm, total width 2,085 mm and total height 3,755 mm, with a mass of 25,000 kg (55,115 lb). The B3 400/4250 has the same three dimensions and weighs 27,000 kg.
04
Maximum stroke is 450 mm and the table-ram distance is 700 mm. Throat depth is 520 mm. The distance between the side frames is 3,600 mm.
