Overview

The DMG Mori NHX 4000 4th Generation is the latest evolution of DMG Mori's best-selling 400mm horizontal machining center, introducing substantive improvements in spindle performance, energy efficiency, and automation readiness over the prior generation. The 4th Generation builds on the proven NHX thermo-symmetric platform with 560 x 560 x 660 mm (22.0 x 22.0 x 26.0 in) of travel and a 400 x 400 mm (15.7 x 15.7 in) pallet, retaining the compact footprint that makes the NHX 400mm class ideal for high-density production cells.

The headline upgrade is the 4th-generation speedMASTER spindle, now delivering 22 kW (30 hp) and 162 Nm (120 ft-lb) of torque at 12,000 RPM standard, with a 15,000 RPM high-speed option for aluminum-intensive work. The updated spindle design improves thermal stability and tool runout compared to the 3rd generation, contributing to better surface finish and longer tool life. Rapid traverse remains at 60 m/min (2,362 ipm) across all linear axes with roller guideways.

The 4th Generation introduces CELOS X — DMG Mori's updated interface platform — as standard, replacing the older CELOS app ecosystem. CELOS X provides a more streamlined user experience and better integration with factory MES and IoT systems. The machine runs on Fanuc 31i-B5 or Siemens 840D sl depending on customer preference, maintaining G-code compatibility with existing programs.

Automation connectivity is improved: the 4th Generation features standardized robot interface ports and expanded compatibility with DMG Mori's LPP (Linear Pallet Pool) automation system, now supporting up to 24 pallets in a single cell. The standard two-pallet changer achieves a 7.5-second pallet change time, a marginal improvement over the previous generation's 7.9 seconds.

Energy consumption is reduced approximately 20% compared to the 3rd generation through improved servo drive efficiency, LED lighting, and a smarter standby mode that maintains thermal readiness without full-power operation. This contributes to lower operating costs over the machine's life.

With new pricing typically between $320,000 and $430,000, the NHX 4000 4th Generation competes with the Okuma MB-4000HII, Mazak HCN-4000, and Makino A40 in the 400mm HMC class. It is the right machine for automotive, hydraulic, medical, and precision component manufacturers who need compact, fast, thermally stable horizontal machining with a path to scalable automation.

Strengths & Limitations

Strengths

4th-generation speedMASTER spindle delivers 162 Nm of torque — a step up over the prior generation — enabling more aggressive steel roughing through the CAT 40 taper
CELOS X interface provides a cleaner user experience and stronger factory IoT/MES integration than the older CELOS app platform
Approximately 20% energy reduction vs 3rd generation lowers operating costs over the machine life and supports sustainability targets
7.5-second pallet change time with 60 m/min rapids maximizes spindle utilization on short-cycle automotive and hydraulic production
Expanded LPP compatibility for up to 24 pallets enables cost-effective lights-out automation cells without a new machine platform
Thermo-symmetric column with triple-circuit cooling maintains dimensional stability through extended unattended production runs
Roller guideways on all linear axes provide the rigidity needed for aggressive cutting of cast iron and steel, not just aluminum

Limitations

400 kg pallet load restricts tombstone weight compared to 500mm-class machines that allow 500-700 kg
12,000 RPM standard spindle falls short for aluminum-intensive shops; 15,000 RPM upgrade adds cost
40-tool standard magazine is lean for high-mix job shops — plan to budget for 60 or 120-tool expansion
CELOS X ecosystem still requires DMG Mori platform buy-in; shops preferring standalone controls may find it redundant
Premium pricing versus 3rd generation units available on the used market may not be justified for lower-volume shops

Best For

Automotive production cells machining valve bodies, pump housings, and transmission components on 400mm pallets Hydraulic manifold manufacturers running high-volume production where spindle uptime and fast pallet swaps drive output Shops upgrading from 3rd generation NHX 4000 machinery seeking improved spindle performance and energy savings Production cells targeting lights-out automation via DMG Mori LPP with up to 24 pallets Medical device manufacturers running precision steel and titanium components requiring thermal stability and repeatability

Frequently Asked Questions

01 What is new in the NHX 4000 4th Generation vs the 3rd Generation?

The 4th Generation introduces the updated speedMASTER spindle with higher torque (162 vs 157 Nm), CELOS X replacing the older CELOS interface, a 20% reduction in energy consumption, slightly faster pallet change (7.5 vs 7.9 seconds), and expanded LPP automation compatibility for up to 24 pallets. Travels and overall footprint remain unchanged.

02 What does a new NHX 4000 4th Generation cost?

New 4th Generation machines typically price between $320,000 and $430,000. A base configuration with 40-tool magazine and 12,000 RPM spindle starts around $320,000. Expanded ATC (60 or 120 tools), 15,000 RPM spindle, high-pressure coolant, probing, and CELOS X premium packages push toward $430,000. LPP automation adds $200,000-$400,000 depending on pallet count.

03 How does the NHX 4000 4th Generation compare to the Okuma MB-4000HII?

Both are top-tier 400mm HMCs. The Okuma brings its OSP control with Thermo-Friendly Concept thermal compensation and conversational programming. The DMG Mori counters with CELOS X ecosystem, the LPP automation portfolio, and the updated speedMASTER spindle. Choice typically comes down to control preference (Fanuc/Siemens vs Okuma OSP) and existing automation strategies.

04 Can I run existing NHX 4000 programs on the 4th Generation?

Yes. The 4th Generation retains full Fanuc 31i-B5 G-code compatibility. Programs from prior NHX 4000 generations and other Fanuc-controlled machines transfer without modification. CELOS X is a UI layer on top of the standard Fanuc control.

05 What automation options are available?

The standard two-pallet changer is included. DMG Mori offers the LPP Linear Pallet Pool for up to 24 pallets, various robot integration packages for part loading, and the WH Workpiece Handling systems. The 4th Generation has standardized robot interface ports for easier integration with robot cells.
