Overview
The DMG Mori NLX 6000 is the flagship of the NLX universal turning lineup, the biggest and most powerful machine in a family known for best-in-class rigidity and thermal stability. With a maximum turning diameter of 920 mm (36.2 in), turning length up to 3,050 mm (120.1 in), and a 37 kW (49.6 hp) spindle delivering 2,752 Nm of torque, the NLX 6000 is built for the heaviest turning work in oil and gas, power generation, heavy equipment, and large-scale aerospace manufacturing.
The A2-15 spindle nose with standard 24-inch (610 mm) chuck grabs workpieces that would dwarf anything in the NLX 4000 or 3000. Bar capacity is 165 mm (6.5 in), accommodating large-diameter bar stock and heavy-wall tubing. The spindle runs at 1,800 RPM, trading speed for the massive torque needed to take deep cuts on large-diameter stock in steel, stainless, and superalloys. A programmable servo-driven tailstock with MT6 taper supports long workpieces.
The BMT turret system is available in BMT 80 configuration with 12 tool stations. Driven tools spin at up to 6,000 RPM with up to 80 Nm of torque, providing milling capability proportional to the workpiece size. The optional Y-axis adds plus/minus 80 mm of travel. Box guideways on all axes and a machine weight exceeding 20,000 kg (44,092 lb) provide the mass and damping needed for vibration-free heavy cuts.
Thermal displacement control with cooled ball screws, spindle temperature management, and bed temperature control is critical at this machine size, where thermal growth across large castings can cause significant dimensional shift. The NLX 6000 comes in multiple bed lengths: /1500, /2000, and /3000 between centers.
The NLX 6000 runs CELOS with Mitsubishi MAPPS or Siemens underneath. Pricing starts around 50,000 for a base configuration and can exceed 00,000 fully loaded. Used NLX 6000 machines from 2014-2020 trade between 80,000 and 00,000. At this scale, the NLX 6000 competes with large-frame lathes from Mazak, Okuma, Mori Seiki legacy models, and European builders like Weiler and EMCO.

Strengths & Limitations
Strengths
- 920 mm turning diameter and 3,050 mm turning length handle the largest production turning work available in a universal turning center
- 2,752 Nm spindle torque provides the brute force for deep cuts on large-diameter stock in steel, stainless, and superalloys
- 165 mm bar capacity is the largest in the NLX family, accommodating heavy-wall tubing and large bar stock for production work
- 20,000+ kg machine mass with box guideways provides the vibration damping that heavy-duty large-diameter turning demands
- BMT 80 turret with driven tools eliminates transferring large workpieces to a boring mill or VMC for milled features
- Thermal compensation across the massive machine structure holds tolerances that would drift significantly on uncompensated large lathes
Limitations
- 1,800 RPM max spindle speed makes the NLX 6000 impractical for small-diameter work and limits surface footage even on mid-size parts
- Starting at 50K and exceeding 00K, it requires a consistent flow of large-part work to justify the investment
- 20,000+ kg weight demands a specially engineered foundation and substantial rigging expense, adding 0,000-0,000 to installation costs
- 6,000 RPM driven tool speed on the BMT 80 is lower than the 10,000-12,000 RPM on smaller NLX machines, limiting milling productivity
- DMG Mori service on a machine this size involves specialty technicians and parts at premium pricing

Frequently Asked Questions
01
A new NLX 6000 starts around 50,000 in base configuration. Fully loaded with BMT 80 turret, Y-axis, programmable tailstock, and the /3000 bed length, pricing can exceed 00,000. Used machines from 2014-2020 sell between 80,000 and 00,000.
02
The NLX 6000 nearly doubles the turning diameter (920 mm vs 500 mm), increases torque (2,752 Nm vs 1,550 Nm), and offers a larger chuck (24-in vs 15-in). Bar capacity jumps to 165 mm from 102 mm. The NLX 6000 is for a completely different scale of work.
03
The NLX 6000 comes in /1500, /2000, and /3000 bed lengths. The /3000 provides over 10 feet of turning length for the longest shaft work.
04
At 20,000+ kg, the NLX 6000 requires a specially engineered concrete foundation with reinforcement designed for the static and dynamic loads. Foundation engineering should be done in consultation with DMG Mori installation team before ordering.
05
Yes. The BMT 80 turret provides up to 6,000 RPM driven tools with 80 Nm torque. Combined with optional Y-axis, it handles flats, keyways, cross-holes, and drilling on large parts without transferring to a second machine.
