Price estimate
We do not have a price for the Salvagnini B3 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 170/4250 is the standard-frame B3 for four-metre work in medium gauge: 170 tons on a 4,250 mm (167.3 in) table, with the 250 mm/s ram of the lighter machines.
It occupies the same space as the B3 135/4250. Both are listed at 5,310 mm long, 1,735 mm wide and 3,295 mm high, with a mass of 13,500 kg (29,762 lb). The extra force costs nothing in footprint, only a higher average consumption of 2 kWh.
The working window is the standard one: 435 mm throat, 350 mm stroke, 600 mm table-ram distance, and 3,640 mm between the side frames. Two other 170 ton machines share this table length and are worth comparing. The B3 170/4250XL opens the stroke to 450 mm for deeper parts at 220 mm/s. The B3 AU-TO 170/4250 adds automatic tool set-up.
On a bed this long, set-up time is often spent building tool stations of different lengths. The ATA device changes and adjusts the upper tool length automatically, and ATA.L does the same for the lower tools, which Salvagnini recommends for kit production where parts of different lengths are bent in sequence.

Strengths & Limitations
Strengths
- 170 tons on a 4,250 mm (167.3 in) table
- Same footprint and 13,500 kg mass as the B3 135/4250
- 250 mm/s approach and return, the fastest ram among the 170 ton, 4,250 mm models
- ATA and ATA.L adjust upper and lower tool lengths automatically
- 3,640 mm between the side frames
Limitations
- Stroke of 350 mm and table-ram distance of 600 mm; deeper parts call for the B3 170/4250XL
- Throat depth of 435 mm, as on the other standard frames
- Tool set-up is manual unless ATA devices are specified
- Needs 5,310 mm of length on the floor

Frequently Asked Questions
01
The B3 170/4250 has a 350 mm stroke and a 250 mm/s approach speed. The B3 170/4250XL has a 450 mm stroke and 520 mm throat at 220 mm/s. The B3 AU-TO 170/4250 keeps the standard stroke and adds the automatic tool change device. Decide by part depth first, then by how often tools change.
02
The mass is 13,500 kg (29,762 lb). Total length is 5,310 mm, total width 1,735 mm and total height 3,295 mm. Average consumption is listed at 2 kWh.
03
ATA, the Automatic Tool Adjuster, changes and automatically adjusts the length of the upper bending tool. ATA.L does this for the lower tools and suits kit production, because parts of different lengths can be bent one after another.
04
Maximum stroke is 350 mm and the table-ram distance is 600 mm. Throat depth is 435 mm and the distance between the side frames is 3,640 mm, on a table 4,250 mm (167.3 in) long.
