DN Solutions DNM 4000

The DN Solutions DNM 4000 is a compact vertical machining center with 520 × 400 × 480 mm (20 × 16 × 19 in) of travel, a 12,000 rpm direct-coupled spindle and a rapid traverse of 48 m/min (1,890 ipm). It weighs 3,300 kg (7,275 lb).

Speed is what sets it apart from the larger machines of the series. The DNM 4500 4TH lists 8,000 rpm and 42 m/min (1,654 ipm) on X and Y, both lower than the figures here, while its 117.8 N-m (87 ft-lb) of torque is practically the same as the 117 N·m (86 ft-lb) of the DNM 4000. The small machine therefore keeps the torque and gains spindle speed and axis speed, which pays on short-cycle parts where positioning and tool changes make up much of the clock.

The table measures 650 × 400 mm (26 × 16 in) and carries 400 kg (882 lb). Y travel equals the 400 mm table depth, so the whole depth is usable. X travel is 520 mm against 650 mm of table length, which means the spindle cannot reach the two ends. Treat that margin as clamp space and keep the parts inside the travel.

DN states that the direct-coupled spindle improves on belt-driven types, and that grease lubrication for the axis roller guideways is supplied as standard. An EOP function is reached through a pop-up window on the NC main screen. The table for this model gives no spindle power, taper or tool capacity, so confirm those on the quotation.

The listed dimensions are 2,858 × 1,650 × 2,753 mm (113 × 65 × 108 in). With one floor dimension at only 1,650 mm (65 in), the machine suits a row of machines or a cell where space between neighbours is short.
