Our best estimate for the DMG Mori NEF 400 is $120,000 – $185,000. This is an estimate for a cnc lathes / turning centers in this class, not a quote from DMG Mori; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/dmg-mori-nef-400-lathe#price; the request is passed to DMG Mori or an authorised dealer.
It is not in DMG MORI's current lineup, so anyone considering one is considering a used machine. The listed figures are a guide. The points that vary between machines are the V3 version with driven tools and C-axis, and the optional chip conveyor, so check both on the machine itself.
An ISM 65 integrated spindle motor with 4,500 rpm. Listed power is 11.5 kW at 40% ED and 8 kW at 100% ED (15.4 / 10.7 hp), and torque is 340 Nm at 40% ED and 240 Nm at 100% ED. The spindle bore is 87 mm, the drawbar inner diameter 67 mm, bar capacity 65 mm (2.56 in) and the maximum chuck diameter 250 mm (10 in).
Only in the optional machine version V3. That version has 6 driven tool stations in the 12 x VDI30 turret, with 4,500 rpm, 5.5 kW and 17.5 Nm at 40% ED, and a C-axis with 0.001° resolution. No Y-axis is listed, so milling is limited to what the C-axis and X and Z can reach.
The machinable workpiece length with the tailstock is 650 mm (25.6 in). The distance from spindle to tailstock is 902.5 mm (35.5 in) without a chuck, and the turret slide has 800 mm (31.5 in) of Z travel. The hydraulic tailstock has a 680 mm stroke, 6.8 kN of force and an MK 4 centre.
3,500 kg (7,716 lb) without the chip conveyor and 3,700 kg with the optional chip conveyor. The NEF 600 is in a different class at approximately 11,000 kg, with a 400 mm (15.7 in) chuck against the 250 mm (10 in) maximum chuck diameter of the NEF 400.
