How much does the Dener XL 40320 cost?
Price estimate
We do not have a price for the Dener XL 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
At 320 ton the Dener XL 40320 moves the four-metre Smart XL press brake into plate work. Bending length is 4,050 mm (159.4 in), and the frame around it is visibly heavier than on the two lighter versions: 17,500 kg (38,580 lb).
The ram opens further here. Dener gives this size a 400 mm stroke and 650 mm of daylight, so the taller dies and wide V-openings that thick material calls for still leave working room. Throat depth remains 450 mm, and 3,550 mm are free between the side frames.
Driving 320 ton takes a 30 kW (40.2 hp) main motor and 400 lt of oil. Ram speeds come down accordingly, to 125 mm/sec approach and 120 mm/sec return, with 10 mm/sec while bending. On plate parts handled by crane, the ram is seldom what sets the cycle time.
Two things belong on the checklist for a machine like this. First the crowning: the standard system is manual, and Dener lists a motorized one as an option. Second the oil temperature on long shifts, for which a hydraulic oil cooling system is offered, again as an option.

Strengths & Limitations
Strengths
- 320 ton over 4,050 mm for plate at full length
- 400 mm stroke and 650 mm daylight, larger than on the XL 40220
- 30 kW (40.2 hp) main motor with a 400 lt tank
- 3,550 mm between the side frames
Limitations
- 17,500 kg (38,580 lb) needs a proper foundation
- Approach of 125 mm/sec and return of 120 mm/sec are slower than the lighter models
- Throat depth is 450 mm; the 600 mm throat starts with the XL 40400

Frequently Asked Questions
01
320 ton across a bending length of 4,050 mm (159.4 in). The distance between the side frames is 3,550 mm and the throat is 450 mm deep.
02
A 400 mm stroke and 650 mm daylight. Both exceed the 350 mm and 600 mm of the XL 40220, which helps with the tall tooling used on thick material.
03
It weighs 17,500 kg (38,580 lb), is 4,780 mm long and up to 3,100 mm high. The main motor is 30 kW (40.2 hp); voltage is not stated in the table.
04
No. A hydraulic oil cooling system appears under optional equipment for the XL series. The oil tank itself holds 400 lt on this model.
