Price estimate
We do not have a price for the Salvagnini B3 AU-TO 170/4250 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 170/4250 is a 170 ton press brake that sets up its own tools. AU-TO is Salvagnini's automatic tool change device, and this is the lightest of the three B3 models built around it.
The bending figures follow the standard-frame B3 170/4250: 435 mm throat, 350 mm maximum stroke, 600 mm table-ram distance, 3,640 mm between the side frames and a 250 mm/s approach and return speed. The table is 4,250 mm (167.3 in) long, but note the footnote Salvagnini attaches to it: automatic tools set up L = 3060 mm. In other words the tool changer covers 3,060 mm of the table, so check that the longest tool station the parts need falls inside that length.
The device adds bulk. Against the B3 170/4250 the mass rises from 13,500 kg to 15,500 kg (34,171 lb), total length from 5,310 mm to 5,560 mm and width from 1,735 mm to 2,170 mm. Height is 3,290 mm and average consumption 2 kWh.
Salvagnini pitches AU-TO at production where all parameters change frequently. It does not disable the ATA tool length adjusters; it prepares the machine and applies the tool set-up strategy to the production flow. A Radar safety system is integrated into press brakes with automatic ATA and AU-TO tool change, and it distinguishes the operator's movements from inanimate objects near the work area.

Frequently Asked Questions
01
AU-TO is the automatic tool change device: it automatically sets up the tools. Salvagnini describes it as the answer to frequent change of all parameters. It works with the ATA devices and applies the tool set-up strategy that suits the production flow.
02
Salvagnini's table lists the table length as 4,250 mm (167.3 in) with a footnote: automatic tools set up L = 3060 mm. The page does not explain it further. Read it as the length served by the automatic set-up and confirm with Salvagnini for parts needing longer tooling.
03
The B3 170/4250 is 5,310 mm long, 1,735 mm wide and weighs 13,500 kg. The B3 AU-TO 170/4250 is 5,560 mm long, 2,170 mm wide and weighs 15,500 kg (34,171 lb). Height is 3,290 mm.
04
By the Radar safety system, which is integrated into press brakes with automatic ATA and AU-TO tool change. Its sensors detect the operator's movements, tell them apart from inanimate objects near the work area, and block operations when there is a potential danger.
