How much does the Durma AD-S 40320 cost?
Price estimate
We do not have a price for the Durma AD-S 40320 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
Twenty tonnes of frame, 320 ton of force and a 4,050 mm (159.4 in) bed: the Durma AD-S 40320 is the four-metre plate machine of the AD-S hydraulic press brake series for shops that don't need the largest model.
It keeps the wide column spacing of the lighter four-metre machines, 3,600 mm (141.7 in). That is its main advantage over the AD-S 40400, where the columns stand 3,400 mm (133.9 in) apart. A wide plate with a deep flange has more room here.
Like every AD-S model of this force or more, it has the tall opening: a 365 mm (14.4 in) stroke and 630 mm (24.8 in) of daylight. The table is 154 mm (6.1 in) in its narrow form and 300 mm (11.8 in) in its wide form.
A 37 kW (49.6 hp) motor works from a 250 L tank. The beam approaches at 160 mm/sec, bends at 10 mm/sec and returns at 140 mm/sec. None of those figures is lower than on the AD-S 40220, so the extra force does not slow the cycle. Durma gives the weight as 20,000 kg (44,092 lb). The machine is 5,300 mm (208.7 in) long, 1,910 mm (75.2 in) wide and 3,330 mm (131.1 in) high. Table height remains 900 mm (35.4 in), a normal working height, which the AD-S 40400 and the AD-S 60400 do not keep.
Plate of this size is heavy to hold during the bend. Durma lists robot integration and motorized back gauges as options; sheet followers do not appear in the AD-S equipment list.

Frequently Asked Questions
01
It applies 320 ton over a bending length of 4,050 mm (159.4 in). The same force is available on a shorter bed as the AD-S 30320, which has a bending length of 3,050 mm (120.1 in).
02
The AD-S 40400 has 400 ton and a 510 mm (20.1 in) throat, but its table is 1,050 mm (41.3 in) high and it weighs 27,760 kg (61,199 lb). The AD-S 40320 keeps a 900 mm (35.4 in) table and 3,600 mm (141.7 in) between the columns.
03
Daylight is 630 mm (24.8 in) and the stroke 365 mm (14.4 in). That leaves room for tall punches and wide dies together, and for a deep part to be lifted out after the bend.
04
Motor power is 37 kW (49.6 hp) and the oil tank holds 250 L. Durma offers an oil cooler or an oil heater as optional equipment. Y axis precision is listed at 0.01 mm.
