How much does the Durma HD-FN 4020 cost?
Price estimate
We do not have a price for the Durma HD-FN 4020 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 Durma HD-FN 4020 is the mid-size bed in the HD-FN fiber laser range. It takes 4,064 x 2,032 mm (160.0 x 80.0 in) sheet on axis travels of 4,100 mm (161.4 in) in X and 2,070 mm (81.5 in) in Y, and Durma offers the series with laser power up to 20 kW.
Why this size? A 2,032 mm wide bed takes wide plate that the smaller bed cannot load at all, and the 4,064 mm length lets two shorter blanks sit end to end for nesting. The HD-FN 3015 stops at 3,048 x 1,524 mm (120.0 x 60.0 in). The HD-FN 6020 keeps this width and adds length.
Durma prints the dynamic figures of the series under the heading of the HD-FN 3015: 141 m/min synchronized speed, 14 m/s² and ±0.05 mm. The table gives no separate speed or accuracy rows for this bed, so ask for them rather than assume the smaller machine's values carry over to a longer, wider gantry.
What is stated for this size is the load. A single table carries 240 kg/m² with sources up to 12 kW and 400 kg/m² with 15-20 kW. On the brochure's capacity table a 12 kW source cuts 30 mm mild steel, 25 (30) mm stainless steel and 30 (40) mm aluminium, the bracketed values being thicknesses still cut with minimal burr formation. Brass is listed at 20 mm and copper at 15 mm for the same power. The Z axis is printed as 125 (270) mm.

Frequently Asked Questions
01
The maximum sheet size is 4,064 x 2,032 mm (160.0 x 80.0 in). Axis travel is 4,100 mm (161.4 in) in X and 2,070 mm (81.5 in) in Y, and the Z axis is printed as 125 (270) mm.
02
Durma states laser power up to 20 kW for the HD-FN. Its capacity table lists 3 kW, 4 kW, 6 kW, 12 kW and 20 kW columns. For mild steel the values are 16 (20) mm, 20 (22) mm, 25 mm, 30 mm and 40 (50) mm in that order.
03
Only in bed length, as far as the table shows. The HD-FN 6020 takes 6,096 x 2,032 mm (240.0 x 80.0 in) sheet on 6,100 mm (240.2 in) of X travel. Y travel is 2,070 mm (81.5 in) on both, and the sheet weight limits per square metre are identical.
04
Durma does not print dynamic figures for this size. The series table gives them for the HD-FN 3015 only: 100 m/min per axis, 141 m/min synchronized speed and 14 m/s² synchronized acceleration. Confirm the values for the larger bed with Durma.
