DMG Mori NLX 2500

The DMG MORI NLX 2500 is a universal turning center with a Y-axis and a driven-tool turret, taking workpieces up to 460 mm (18.1 in) in diameter and bar up to 90 mm (3.5 in). It is built in two bed lengths. Type 700 has 795 mm (31.3 in) of Z travel and a maximum workpiece length of 705 mm (27.8 in). Type 1250 has 1,345 mm (53 in) of Z travel and takes parts up to 1,255 mm (49.4 in) long. X travel is 260 mm (10.2 in) and Y travel is 100 mm (3.9 in) on both.

Bed length is the first decision, because nothing else in DMG MORI's table changes between the two types. The Type 700 is the short-bed machine for chuck parts and bar. The Type 1250 is the same cross-section stretched for shafts. The 90 mm (3.5 in) bar capacity sits well below the 460 mm (18.1 in) workpiece diameter, so the larger diameters are chucked as billets, castings or forgings and only the smaller work feeds through the spindle.

Milling is done from the turret. It is a BMT (Built-in Motor Turret), meaning the motor for the rotary tools sits inside the turret, and DMG MORI gives the rotary tool spindle speed as 10,000 rpm. With 100 mm (3.9 in) of Y travel that covers cross holes, flats, keyways and off-centre drilling in the same clamping as the turning. The Y stroke sets the width of any feature that has to be milled off the centreline.

X, Y and Z all run on slideways, which DMG MORI lists under rigidity; sliding ways damp vibration better than rolling guides in heavy or interrupted cuts. Thermal displacement control is part of the design, and there is an energy-saving setting that displays the saving. A quick-change turret is listed as an option, so it is not on the base machine.

Among the neighbouring models, the NLX 1500 and NLX 2000 share the 260 mm (10.2 in) X and 100 mm (3.9 in) Y travels but stop at 590 mm (23.2 in) of Z. The NLX 2500 2nd Generation keeps the same X and Z travels and has 120 mm (4.7 in) of Y.
