Price estimate

Uncertain

We do not have a price for the DMG Mori NLX 4000 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 DMG MORI NLX 4000 is a large universal turning center: 600 mm (23.6 in) maximum workpiece diameter, 365 mm (14.4 in) of X travel and 117 mm (4.6 in) of bar capacity, in two lengths. The Type 750 has 875 mm (34.4 in) of Z travel and takes parts up to 746 mm (29.4 in) long. The Type 1500 has 1,685 mm (66.3 in) of Z and takes 1,584 mm (62.4 in). Y travel is 120 mm (4.7 in).

What DMG MORI stresses on this model is the structure. Compared with its conventional machine, the slideway area is up 50% on the X-axis and 90% on the Z-axis, and large-diameter ball screws are fitted. More bearing area under the saddle and cross slide spreads the cutting load, which counts at this size: a 600 mm (23.6 in) part puts the tool a long way from the spindle centreline and the roughing cuts are heavy.

The spindle has a through hole that DMG MORI gives as 5.7 in / 7.3 in. The table's bar capacity is 117 mm (4.6 in), so if a job depends on passing large bar or tube, check which through-hole version, chuck and draw tube a quoted machine carries.

Milling is by BMT (Built-in Motor Turret). Maximum driven tool torque is 73.8 ft lbf on a 4 min rating and 50.2 ft lbf continuous. The continuous figure is the one to plan long milling operations around. C-axis positioning accuracy is listed as 6.8 sec, which governs how accurately milled and drilled features index around the part.

Coolant circulation inside the castings is listed for the 750 type as part of thermal displacement control. In the range, the NLX 3000 sits below with 280 mm (11 in) of X travel. The NLX 6000 sits above with 485 mm (19.1 in) of X, 200 mm (7.9 in) of Y and 2,150 mm (84.6 in) of Z.

Strengths & Limitations

Strengths

600 mm (23.6 in) maximum workpiece diameter with 365 mm (14.4 in) of X travel
Slideway area is up 50% on the X-axis and 90% on the Z-axis over DMG MORI's conventional machine, with large-diameter ball screws
Through-spindle hole of 5.7 in / 7.3 in, with a listed bar capacity of 117 mm (4.6 in)
BMT turret with a maximum driven tool torque of 73.8 ft lbf on a 4 min rating
C-axis positioning accuracy listed as 6.8 sec
Two lengths: Type 750 for parts up to 746 mm (29.4 in), Type 1500 for parts up to 1,584 mm (62.4 in)

Limitations

Continuous driven tool torque is 50.2 ft lbf; the 73.8 ft lbf figure is a 4 min rating
Coolant circulation inside the castings is listed only for the 750 type
Only two bed lengths, with a longest part of 1,584 mm (62.4 in); the NLX 3000 is offered with up to 3,170 mm (124.8 in) of Z travel
Y travel is 120 mm (4.7 in), against 200 mm (7.9 in) on the NLX 6000

Best For

Large chuck work up to 600 mm (23.6 in) in diameter Heavy roughing that loads the enlarged slideways and large-diameter ball screws Tube and large bar passed through the 5.7 in / 7.3 in spindle hole Shafts up to 1,584 mm (62.4 in) long on the Type 1500

Frequently Asked Questions

01 What is the difference between the NLX 4000 Type 750 and Type 1500?

The Type 750 has 875 mm (34.4 in) of Z travel and a maximum workpiece length of 746 mm (29.4 in). The Type 1500 has 1,685 mm (66.3 in) of Z travel and takes 1,584 mm (62.4 in). DMG MORI also lists coolant circulation inside the castings for the 750 type only. X travel, Y travel, workpiece diameter and bar capacity are the same.

02 How big a bar or tube can pass through the NLX 4000 spindle?

The table gives a maximum bar capacity of 117 mm (4.6 in). DMG MORI's highlights give the through-spindle hole diameter as 5.7 in / 7.3 in. The two figures are not the same thing: usable bar size also depends on the chuck and draw tube, so confirm the configuration quoted.

03 How much milling torque does the NLX 4000 turret have?

DMG MORI gives the maximum as 73.8 ft lbf, rated for 4 min, and 50.2 ft lbf continuous. The turret is a BMT (Built-in Motor Turret), with the tool drive motor built into the turret. Plan long milling operations on the continuous figure.

04 What has DMG MORI done to the NLX 4000 structure for rigidity?

Three things are listed. The slideway area is up 50% on the X-axis and 90% on the Z-axis compared with DMG MORI's conventional machine. Large-diameter ball screws are used. DMG MORI also lists the 5.7 in / 7.3 in through-spindle hole under the same heading.

05 Where does the NLX 4000 sit between the NLX 3000 and the NLX 6000?

By X travel it is the middle machine: the NLX 3000 has 280 mm (11 in), the NLX 4000 has 365 mm (14.4 in) and the NLX 6000 has 485 mm (19.1 in). The NLX 3000 and NLX 4000 share 120 mm (4.7 in) of Y travel, while the NLX 6000 has 200 mm (7.9 in).
