Overview

The DMG Mori NLX 6000 Y is the Y-axis-equipped flagship of the NLX universal turning lineup, combining the NLX 6000 platform's extreme turning capability — 920 mm (36.2 in) diameter, 2,752 Nm of torque — with Y-axis off-center milling capability for the most demanding large shaft and chucking work in industrial manufacturing. This machine is built for the segment where raw material values justify done-in-one processing: oil and gas wellhead equipment, power generation shafts, large pump and compressor components, and marine propulsion hardware.

The Y-axis on the NLX 6000 Y provides plus/minus 80 mm of travel from centerline (160 mm total). On a machine swinging 920 mm diameter, this Y-axis reach enables off-center drilling of bolt circles, radial milled flats, keyways, and complex features on very large flanged and shaft components that previously required costly transfer to a large horizontal boring mill or machining center. For high-value components where every transfer is a risk of damage or dimensional deviation, the NLX 6000 Y provides the most complete single-platform solution at this scale.

The A2-15 spindle nose with standard 24-inch (610 mm) chuck grabs the largest workpieces in the NLX family. The machine runs at 1,800 RPM maximum, with 37 kW (49.6 hp) and 2,752 Nm of torque — numbers that reflect the machine's primary mission of deep, aggressive turning in heavy stock. The BMT 80 driven turret provides up to 6,000 RPM with 80 Nm of torque for live tooling operations on large diameter workpieces, proportional to the scale of work.

Bar capacity of 165 mm (6.5 in) accommodates large-diameter bar stock and heavy-wall tubing for production bar-fed work at the top of the large-lathe segment. Box guideways on all axes and over 20,000 kg (44,092 lb) of machine mass provide the vibration damping and rigidity that aggressive large-diameter turning demands. Thermal displacement control across the massive machine structure is essential — uncompensated thermal growth in a machine this size can cause significant dimensional deviation.

Control runs CELOS with Siemens 840D solutionline, providing the full CELOS app suite for production monitoring, tool management, and process documentation. The NLX 6000 Y occupies a very small segment of the global machine tool market — there are very few machines capable of turning 920 mm diameter parts with off-center Y-axis milling capability at this level of rigidity and precision.

Strengths & Limitations

Strengths

Y-axis at plus/minus 80 mm enables off-center milling and drilling on 920 mm diameter workpieces, eliminating transfer to a boring mill for bolt circles and radial features
2,752 Nm spindle torque is the highest in the NLX lineup, providing the brute force for deep cuts in large-diameter steel, stainless, and superalloys
920 mm turning diameter handles the largest shaft and chucking components encountered in oil and gas, power generation, and marine manufacturing
165 mm bar capacity — the largest in the NLX family — supports production operations on heavy-wall tubing and large bar stock
24-inch chuck provides secure grip on very large workpieces, critical for deep roughing cuts at the limits of the turning envelope
BMT 80 driven turret eliminates secondary machine setups for milled features on large components, reducing handling risk on high-value parts
Box guideways and 20,000+ kg machine mass provide the vibration damping for consistent surface finish on large-diameter turning

Limitations

1,800 RPM max spindle speed limits the machine entirely to large-diameter heavy-duty work — entirely unsuitable for small-diameter or high-speed applications
Y-axis travel of plus/minus 80 mm is proportionally smaller relative to part size than on mid-size Y-axis lathes — sufficient for most features but not deep complex milling
BMT 80 driven tools at 6,000 RPM are slower than driven tools on smaller BMT turrets — fine for drilling and facing, limiting for deep milling operations
20,000+ kg foundation requirement and rigging costs add $50,000-$100,000 to total installation expense
At $450K-$700K, the NLX 6000 Y requires a consistent flow of high-value large-part work to achieve acceptable ROI
Limited availability of service technicians experienced with machines in this size class can extend repair lead times

Frequently Asked Questions

01 What does a DMG Mori NLX 6000 Y cost?

A new NLX 6000 Y starts around $450,000 in base /1500 configuration. The /2000 and /3000 bed options with BMT 80 turret, Y-axis, and full Siemens control push pricing to $550,000-$700,000. Used machines from 2014-2022 sell for $250,000-$450,000 depending on condition, bed length, and options.

02 NLX 6000 Y vs NLX 4000 Y — which should I choose?

If your maximum turning diameter is 500 mm or less, the NLX 4000 Y provides the same Y-axis capability at significantly lower cost with more spindle speed (2,500 vs 1,800 RPM). Choose the NLX 6000 Y only when your parts consistently require more than 500 mm turning diameter or more than 102 mm bar capacity. The NLX 6000 Y costs $150,000-$250,000 more than a comparable NLX 4000 Y.

03 What foundation does the NLX 6000 Y require?

At 20,000+ kg machine weight, the NLX 6000 Y requires a purpose-engineered reinforced concrete foundation designed by a structural engineer in consultation with DMG Mori installation specifications. Budget $40,000-$80,000 for foundation work. Crane access above the machine is required for part loading.

04 Can the NLX 6000 Y handle drilling and tapping on large flanges?

Yes. The BMT 80 turret provides 6,000 RPM driven tools with 80 Nm of torque. Combined with the Y-axis and C-axis, the machine drills bolt circles, taps holes, mills flats, and cuts keyways on large flanged components. For very large bolt circles, Y-axis positioning reaches plus/minus 80 mm from centerline.

05 Is a tailstock available on the NLX 6000 Y?

Yes. The NLX 6000 Y includes a programmable servo-driven tailstock with MT6 taper for supporting long shaft workpieces. The servo-driven tailstock allows programmable positioning and quill pressure, critical for consistent support during long-shaft roughing and finishing operations.
