Overview

The DMG Mori NHX 4000 is a 400mm-class horizontal machining center built on DMG Mori' speedMASTER spindle platform, targeting high-volume production of smaller prismatic parts with fast cycle times and solid thermal stability. The third generation of the NHX platform delivers 560 x 560 x 660 mm (22.0 x 22.0 x 26.0 in) of X/Y/Z travel with a 400 x 400 mm (15.7 x 15.7 in) pallet, putting it squarely in the compact HMC segment where floor space matters as much as metal removal rate.

The standard speedMASTER spindle turns at 12,000 RPM through a CAT 40 (BBT 40) taper, producing 22 kW (30 hp) and 157 Nm (116 ft-lb) of torque. A 15,000 RPM high-speed option is available for shops running aluminum-dominant work. Rapid traverse hits 60 m/min (2,362 ipm) on all three linear axes with roller guideways providing the rigidity needed for aggressive steel cutting while maintaining surface finish quality.

The two-pallet changer comes standard, and tool storage starts at 40 positions in a drum-type magazine expandable to 60 or 120 tools. Pallet change time sits at 7.9 seconds, keeping spindle utilization high during production runs. The machine runs on CELOS with a Fanuc 31i-B5 or MAPPS V control, giving operators a familiar interface with DMG Mori' app-based CELOS ecosystem layered on top for job management and process monitoring.

Thermal stability is a standout feature on the NHX platform. DMG Mori' cooling system circulates temperature-controlled coolant through the spindle, ball screws, and column structure, keeping thermal drift within tight limits during extended unattended runs. The machine also features a thermo-symmetric design philosophy that minimizes dimensional shift as the shop environment changes throughout the day.

The NHX 4000 competes directly with the Okuma MB-4000HII, Mazak HCN-4000, and Makino A40 in the 400mm HMC class. New machines typically price between $295,000 and $400,000 depending on spindle selection and automation options. Used units from 2016-2022 trade in the $120,000 to $220,000 range. For shops running smaller automotive components, valve bodies, hydraulic manifolds, and similar parts that fit within a 400mm pallet, the NHX 4000 delivers excellent throughput per square foot with DMG Mori' global service backing.

Strengths & Limitations

Strengths

Compact 400mm pallet footprint maximizes shop floor density for high-volume production cells running smaller prismatic parts
speedMASTER spindle with 157 Nm of torque handles aggressive steel roughing despite the CAT 40 taper, bridging the gap between light-duty and heavy-cutting platforms
Thermo-symmetric column design and comprehensive cooling system maintain dimensional stability during extended unattended runs across temperature swings
CELOS interface with Fanuc control underneath gives operators a modern touchscreen experience while keeping Fanuc G-code compatibility that most shops already know
60 m/min rapids on roller guideways keep non-cutting time low, critical for short-cycle automotive and hydraulic component work
Two-pallet changer standard with 7.9-second pallet swap time keeps spindle utilization above 85% in typical production scenarios
Strong automation ecosystem including DMG Mori LPP linear pallet pool and robot integration packages for scaling to lights-out production

Limitations

400 kg pallet load limit restricts tombstone weight for multi-sided fixturing compared to 500mm-class machines that typically allow 500-700 kg
40-tool standard magazine is thin for high-mix job shops and the 120-tool expansion adds significant cost to the base configuration
12,000 RPM standard spindle falls short for high-speed aluminum work and shops cutting mostly non-ferrous should budget for the 15,000 RPM upgrade
CELOS ecosystem requires DMG Mori ecosystem buy-in and can feel redundant for shops already running enterprise MES/ERP systems

Best For

Automotive production cells machining valve bodies, transmission housings, and small engine components on 400mm pallets Hydraulic manifold shops running high-volume production where compact HMC footprint and fast pallet changes drive throughput Job shops adding horizontal machining capability for the first time without committing to the cost and floor space of a 500mm platform Shops building multi-machine production cells with DMG Mori LPP linear pallet pool automation Medical device manufacturers running high-precision orthopedic and instrument components in steel and titanium

Frequently Asked Questions

01 What does a new DMG Mori NHX 4000 cost?

New NHX 4000 machines start around $295,000 for a base configuration with 40-tool magazine and 12,000 RPM spindle. Adding expanded ATC, high-pressure coolant, probing, and the 15,000 RPM spindle pushes pricing toward $350,000-$400,000. LPP automation systems add $200,000+ depending on the number of pallets. Used NHX 4000 units from 2016-2022 sell for $120,000-$220,000.

02 How does the NHX 4000 compare to the Okuma MB-4000HII?

Both are excellent 400mm HMCs. The Okuma brings Thermo-Friendly Concept thermal stability and the OSP control with conversational programming. The DMG Mori counters with the CELOS ecosystem, a wider automation portfolio through LPP, and arguably better global service coverage. Choice usually comes down to existing shop control preferences and automation plans.

03 Can the NHX 4000 handle steel and cast iron production?

Yes. The speedMASTER spindle with 157 Nm of torque through a BBT 40 taper handles aggressive steel roughing with appropriate tooling. Roller guideways provide rigidity beyond what linear guides deliver. For heavy-duty work, consider the NHX 5500 with CAT 50.

04 What control does the NHX 4000 use?

The NHX 4000 runs CELOS with either a Fanuc 31i-B5 or MAPPS V control depending on market. CELOS provides a touchscreen app-based interface for job management, while the underlying Fanuc control handles G-code programming. Most North American units ship with Fanuc.

05 What automation options are available?

The standard two-pallet changer handles basic automation. DMG Mori offers the LPP (Linear Pallet Pool) system for multi-pallet automation with up to 21 pallets, and various robot integration packages for part loading and unloading.
