We do not have a price for the Salvagnini B3 AU-TO 240/4250 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
With the Salvagnini B3 AU-TO 240/4250, automatic tool change meets the deep frame. It is a 240 ton press brake with a 4,250 mm (167.3 in) table, a 450 mm maximum stroke and a 520 mm throat, and it changes its own tooling through the AU-TO device.
This is the AU-TO model for enclosure and box work. The B3 AU-TO 170/4250 below it has a 350 mm stroke and a 600 mm table-ram distance; here the table-ram distance is 700 mm, so tall tools and deep parts fit. Approach and return speed is 220 mm/s. The distance between the side frames is 3,620 mm.
One detail in Salvagnini's table sets it apart from the other two AU-TO machines. Their table length carries a footnote limiting automatic tools set up to L = 3060 mm, as on the B3 AU-TO 320/4250. The 240 ton model has no such footnote against its 4,250 mm. The page does not say why, so ask what tool length the changer serves on this size.
Compared with the manual-change B3 240/4250, mass grows from 19,400 kg to 21,600 kg (47,619 lb) and width from 2,080 mm to 2,240 mm. Total length is 5,560 mm, height 3,690 mm, and average consumption 2.5 kWh. Salvagnini lists four automation devices for the B3: ATA and ATA.L for tool length, MVM for die opening and AU-TO for the complete set-up.

Frequently Asked Questions
01
The AU-TO automatic tool change device. The B3 240/4250 is 5,330 mm long, 2,080 mm wide and weighs 19,400 kg. The AU-TO version is 5,560 mm long, 2,240 mm wide, 3,690 mm high and weighs 21,600 kg (47,619 lb). Force, table, stroke and speed are the same.
02
Maximum stroke is 450 mm and the table-ram distance is 700 mm. The B3 AU-TO 170/4250 has 350 mm and 600 mm in the same two rows.
03
Four: ATA and ATA.L automatically adjust the length of the upper and lower tools, MVM automatically adapts the die opening, and AU-TO automatically sets up the tools. AU-TO does not disable the operation of the ATA devices.
04
Maximum approach and return speed is 220 mm/s, and bending speed is 15 mm/s as regulated by current standards. Average consumption is listed at 2.5 kWh.
