The DMG Mori NHX-4000 is a 400 mm-pallet CNC horizontal machining center known for rigidity, thermal stability, and unattended reliability in high-mix production shops. This 2017 machine runs a 15,000 RPM spindle over X, Y, and Z travels of roughly 22 x 22 x 26 inches (560 x 560 x 660 mm), and is configured with a twin-pallet automatic pallet changer, full 4th-axis (B-axis) continuous rotation, a 60-tool automatic tool changer, high-pressure through-spindle coolant (TSC), an automatic tool setter, and the DMG Mori M730U (MAPPS) control on a large ERGOline touchscreen. The automatic pallet changer lets one pallet run in the cutting zone while the operator loads and unloads the other, keeping the spindle in the cut and enabling true lights-out production of steel, cast iron, and aluminum parts that demand repeatable accuracy across long runs.
Compared with the earlier DMG Mori NH 4000 it succeeds, the NHX 4000 is a more capable and more thermally stable platform rather than just a newer badge. The NHX generation brought a stiffer bed and column, refined pallet-change and chip-management design, and DMG Mori's current-generation control and high-speed spindle, so a shop sees steadier accuracy over long unattended runs and easier day-to-day operation than the NH-series machines that came before it. For a buyer, that means the throughput and repeatability of DMG Mori's modern horizontal platform in a proven, twin-pallet package with a 15,000 RPM spindle, a 60-tool changer, and through-spindle coolant already in place.
