Overview

The DMG Mori NHX 4000 4th Generation is the latest evolution of DMG Mori's popular 400mm horizontal machining center, featuring the upgraded speedMASTER spindle now running at 20,000 RPM standard with 400V specification, significantly faster rapid traverse, and enhanced automation readiness. The 4th Generation represents a major step over the prior model with a standard high-speed spindle that previously required an upcharge.

Travel dimensions are 560 x 560 x 660 mm (22.0 x 22.0 x 26.0 in) on a 400 x 400 mm (15.7 x 15.7 in) pallet. Maximum workpiece capacity reaches 630 mm (24.8 in) diameter and 900 mm (35.4 in) height at 400 kg (882 lb). The compact footprint makes the NHX 4000 ideal for high-density production cells where multiple machines share limited floor space.

The headline upgrade is the 20,000 RPM speedMASTER spindle now included as standard, eliminating the need for an expensive high-speed option. Feed drive rates reach up to 70,000 mm/min (70 m/min, 2,756 ipm) with acceleration up to 1.2g, enabling extremely fast rapid positioning and reducing non-cutting time. These figures represent significant improvements over the prior generation.

The 4th Generation features CELOS X with MAPPS Fanuc or SIEMENS control options, providing an app-based digital interface with 27 manufacturing applications. Automation connectivity is enhanced with compatibility for RPS, CPP, and LPP pallet systems plus AMR 2000 autonomous material handling. New NHX 4000 4th Generation machines price between $340,000 and $460,000. Specs sourced from DMG Mori published data.

Strengths & Limitations

Strengths

20,000 RPM speedMASTER spindle included as standard eliminates the high-speed upgrade cost of prior generations
70 m/min rapids with 1.2g acceleration dramatically reduce non-cutting time versus 60 m/min on prior models
CELOS X with 27 manufacturing applications provides a modern digital interface for shop floor management
Compatibility with RPS, CPP, LPP pallet systems and AMR 2000 autonomous handling enables scalable automation
Compact 400mm-class footprint supports high-density multi-machine production cells
400V spindle specification improves power delivery efficiency versus older 200V designs

Limitations

400 kg pallet load restricts tombstone weight compared to 500mm-class machines at 500-700 kg
560 x 560 x 660 mm travel limits part size for shops needing larger work envelopes
40-tool standard magazine is lean for high-mix production -- plan for 60 or 120-tool expansion
Premium pricing over prior generation and used NHX 4000 units may not be justified for lower-volume shops

Best For

Automotive production cells machining valve bodies, pump housings, and transmission components on 400mm pallets Aluminum-intensive production where the 20,000 RPM standard spindle maximizes metal removal rates Shops upgrading from prior NHX 4000 generations seeking dramatically faster rapids and standard high-speed spindle Production cells targeting lights-out automation via LPP and AMR 2000 autonomous material handling Medical device manufacturers running precision components requiring high-speed spindle performance

Frequently Asked Questions

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

The 4th Generation makes the 20,000 RPM speedMASTER spindle standard (previously an option), increases rapid traverse to 70 m/min with 1.2g acceleration, adds CELOS X with 27 apps, and introduces AMR 2000 autonomous material handling compatibility.

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

New machines price $340,000-$460,000 depending on tool magazine, automation, and control options. The standard 20,000 RPM spindle is now included in the base price.

03 How does the 4th Generation compare to the NHX 4000 4th (prior model)?

The key differences are the 20,000 RPM standard spindle (vs 12,000 RPM), 70 m/min rapids (vs 60 m/min), 1.2g acceleration, and CELOS X with expanded automation compatibility. The travel envelope and pallet size remain the same.

04 What automation options are available?

The 4th Generation supports RPS pallet systems, CPP circular pallet pools, LPP linear pallet pools, and the AMR 2000 autonomous mobile robot for material handling. Standard robot interface ports enable third-party robot cell integration.
