Price estimate
We do not have a price for the Salvagnini B3 AU-TO 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 AU-TO 320/4250 is the heaviest press brake Salvagnini offers with automatic tool change: 320 tons, a 4,250 mm (167.3 in) table and the AU-TO device.
Automating set-up at this force addresses a real cost. Tools for plate are heavy segments, and changing them by hand is slow and tiring, so the larger the brake the more a tool changer saves on each changeover. Salvagnini's reasoning for AU-TO is frequent change of all parameters, with the device preparing the machine while the ATA adjusters keep working.
As on the B3 AU-TO 170/4250, the table length carries the footnote automatic tools set up L = 3060 mm. Bending capacity is that of the B3 320/4250: a 520 mm throat, 450 mm stroke, 700 mm table-ram distance, 3,600 mm between the side frames and 220 mm/s approach and return.
It is the largest AU-TO machine in every dimension. Total length is 5,700 mm, width 2,245 mm and height 3,740 mm; the mass is 27,200 kg (59,965 lb), up from 25,000 kg for the B3 320/4250. Average consumption is listed at 3.5 kWh. LED lights in the upper and inner sections illuminate the work area and the backgauges, and the LSB laser and camera system can bring the speed-change position to as little as 2 mm from the sheet.

Frequently Asked Questions
01
The B3 AU-TO 320/4250. It has a maximum bending force of 320 tons and a 4,250 mm (167.3 in) table. The other two AU-TO models, the B3 AU-TO 170/4250 and the B3 AU-TO 240/4250, share the table length at lower force.
02
The B3 320/4250 weighs 25,000 kg and is 5,350 mm long and 2,085 mm wide. The B3 AU-TO 320/4250 weighs 27,200 kg (59,965 lb) and is 5,700 mm long and 2,245 mm wide. Its height is 3,740 mm.
03
Salvagnini's table marks the 4,250 mm table length with a footnote: automatic tools set up L = 3060 mm. The page gives no further explanation, so confirm the automatically served tool length for the parts planned.
04
Two sets of LED lights illuminate the work area and the backgauges. The LSB system uses a laser transmitter and HD camera to detect objects in the danger zone. A Radar safety system is integrated into press brakes with automatic ATA and AU-TO tool change.
