How much does the Durma AD-Servo 40320 cost?
Price estimate
We do not have a price for the Durma AD-Servo 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
For general plate work on a four-metre bed, the Durma AD-Servo 40320 offers 320 ton across 4,050 mm (159.4 in). It carries the heavy-duty frame of the series, with a 365 mm (14.4 in) stroke and 630 mm (24.8 in) of daylight, and weighs 20,000 kg (44,092 lb).
The table changes at this size. Where the AD-Servo 40220 has a 104 mm (4.1 in) narrow table, this one is listed at 154 mm (6.1 in) narrow and 300 mm (11.8 in) wide. A wider table carries the large multi-V and wide single-V dies used for plate, at the cost of some freedom on tight Z bends.
Beam speeds are 160 mm/sec for approach and return and 10 mm/sec for bending. The hybrid drive uses 11 x 2 kW of servo-driven pump power and 80 x 2 L of oil. Durma's case for the series is energy: pumps that run only on demand use less power and put less heat into the oil than a motor that idles all shift.
Between the columns there is 3,600 mm (141.7 in), and the throat is 450 mm (17.7 in). The back gauge has 650 mm (25.6 in) of X travel as standard with 1,000 mm (39.4 in) optional, 250 mm (9.8 in) of R travel and a Z working distance of 2,910 mm (114.6 in). The standard control is the SKY 22; the DA-66S and DA-69S are options. The machine is 5,300 mm (208.7 in) long and 3,330 mm (131.1 in) high.
