Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from DMG Mori. Configuration moves it a long way.

Overview

The DMG MORI NHX 4000 4th Generation is a horizontal machining center whose stated figures are mostly about motion: a feed drive of up to 70,000 mm/min, acceleration of up to 1.2 g and a speedMASTER spindle with 20,000 rpm as standard. Its travels are 560 mm (22 in) in X, 560 mm (22 in) in Y and 660 mm (26 in) in Z.

Fast axes only pay off if the table keeps up. DMG MORI lists Servo Sense for Workpiece on the Z and B axes, a function that optimizes table acceleration and deceleration. The load on the table can be anything up to 400 kg (881.8 lb), and acceleration settings fixed for the heaviest case would be slow with a light part. DMG MORI does not describe how the function works, so ask how it responds to different fixture weights.

The bed is described as thick and highly rigid, on a 3 point support structure, with stepped X-axis guideways. DMG MORI adds that the base structure was optimized with analysis technology from the early design stage. None of this comes with a stiffness or accuracy figure.

Chip, coolant and mist control gets its own heading in the Highlights. Stainless steel covers are equipped as standard, and chip conveyor capacity is named for reliable chip evacuation. The ceiling shower coolant with motor-driven nozzle is an option, and for aluminium work that fills the enclosure with chips it is one to consider.

For automation, the machine is stated to be compatible with pallet handling, tool handling and robot systems. The hydraulic / pneumatic interfaces that fixtures need are an option, as is the tool visualizer that automates and quantifies tool measurement. Workpieces are limited to 630 mm (24.8 in) in diameter and 900 mm (35.4 in) in height.

Best For

High-volume small parts where axis acceleration of up to 1.2 g shortens the cycle Automated cells using pallet handling, tool handling or robots Light-alloy machining at up to 20,000 rpm Mixed fixture weights up to 400 kg (881.8 lb) on one machine

Frequently Asked Questions

01 How fast are the axes of the NHX 4000 4th Generation?

DMG MORI states a feed drive of up to 70,000 mm/min and acceleration of up to 1.2 g. Servo Sense for Workpiece on the Z and B axes optimizes the acceleration and deceleration of the table. Both figures carry an up-to qualifier, so treat them as ceilings and not as values for every axis.

02 What automation does the NHX 4000 4th Generation support?

It is stated to be compatible with pallet handling, tool handling and robot systems. The hydraulic / pneumatic interfaces needed for automated clamping are equipped as an option, and so is the tool visualizer for automated tool measurement. Specify both if the machine is going into an unattended cell.

03 How does the machine deal with chips and coolant?

Stainless steel covers are equipped as standard and DMG MORI names chip conveyor capacity for reliable chip evacuation. A ceiling shower coolant with a motor-driven nozzle is available as an option. No coolant pressure, tank volume or conveyor figure is stated in the Highlights.

04 What is the bed construction of the NHX 4000 4th Generation?

A thick, high-rigidity bed with a 3 point support structure and stepped X-axis guideways. DMG MORI states that the base structure was optimized using analysis technology from the early design stage. The Highlights give no machine weight, so foundation and floor loading data must come from the installation documents.

05 Which larger models follow the NHX 4000 4th Generation?

The NHX 5000 4th Generation has 730 mm (28.7 in) of X and Y travel and 880 mm (34.6 in) of Z. Beyond it, the NHX 5500 has 800 mm (31.5 in) of X and Y, and the NHX 6300 has 1,050 mm (41.3 in) of X, 900 mm (35.4 in) of Y and 1,030 mm (40.6 in) of Z.
