Productivity and efficiency kick it up a notch: The NHX4000 is ideal for the horizontal machining of workpieces of up to 24.8 in x 35.4 in, with a loading capacity of up to 880 lb.

The NHX machine concept is based on the successful NH series, with more than 6,000 machines installed worldwide.

The success of the NH series is being continued by DMG/MoriSeiki (Hoffman Estates, IL) with the NHX4000 with regards to a perfect combination of functio­nality, productivity and precision.

This overall performance at Best Price focuses on a compact design of just 12.5 m². The workpiece range of the NHX4000 with 400-pallet comprises workpieces up to 25 in diameter and 35 in height.

In the work area of 22 in x 22 in x 26 in (in X × Y × Z) the horizontal center machines the components extremely accurately and efficiently.

The high demands made on the precision of the NHX4000, which is among other machine tools reflected in a circular accuracy of < 1.7 μm with 1.3 in/sec feed in X and Y as well as 3.9 in radius, go hand in hand with impressive speed and dynamic values.

The linear axes travel at speeds up to 39.4 in/sec, with acceleration values up to 9 m/s². In the process itself, users can choose from spindle rotational speeds in the standard version of up to 12,000 rpm and a torque of 110 Nm. The high-tech module optionally also provides an 12,000 rpm spindle with 30 kW.



The tool management of the NHX4000 is equipped for all requirements. The standard version of the machine has a ring magazine with a capacity of no less than 40 pockets, which can optionally be extended to 60 pockets.

The fast tool changer impresses in all versions with a chip-to-chip time of just up to 2.8 seconds. Together with the pallet changing time of 8 seconds, shortest idle times are thus guaranteed.

Apart from the considerable performance in the process, the NHX4000 also impresses with its low power consumption and reduced operating costs compared to previous models. It has thus been possible to decrease energy demand by up to 50 percent.

The low number of servo motors as well as the LED illumination contributes to this as much as the hydraulic aggregate with pressure accumulator, whose pump is automatically stopped in standby model.

Features include:

  • 15.7 in x 15.7 in and 881.8 lb pallet load
  • 8 m/s² acceleration (Y-axis)
  • < 2.5 μm positioning accuracy
  • < 1.7 μm circular accuracy
  • 2.8 sec chip-to-chip time
  • 450 mm (17.7 in) max. tool length
  • DCG III® (drive near the centre of gravity) ensures low vibration, highest dynamics and precision
  • Direct measuring systems by Magnescale in all axes as standard
  • Energy efficiency: Electricity savings up to 40 percent*
  • High-tech controls: MAPPS IV with 10.4 in TFT display and optional CAM module (Esprit) as well as Siemens 840D operate
