USED DOOSAN NHP 4000 – 2020

The DOOSAN NHP 4000 – 2020 is a high-speed horizontal machining center built for manufacturers that require maximum productivity, exceptional reliability, and advanced automation capabilities. As a member of Doosan’s premium NHP Series, the NHP 4000 was designed to deliver faster cycle times, superior machining accuracy, and increased spindle utilization compared to traditional machining center platforms. The machine combines rigid construction, advanced spindle technology, and automated pallet-changing capability to support demanding production environments across a wide range of industries.

The NHP 4000 features a compact horizontal machining center design that allows manufacturers to efficiently machine complex parts on multiple sides while reducing setup requirements. The horizontal spindle orientation naturally improves chip evacuation by allowing chips to fall away from the workpiece during machining. This reduces heat generation, improves cutting conditions, extends tool life, and helps maintain consistent surface finishes throughout long production runs.

Built on a heavily reinforced cast iron structure, the machine provides outstanding rigidity and vibration dampening. Roller-type linear guideways and high-speed servo systems enable fast positioning and precise motion control, allowing the machine to achieve high productivity without sacrificing accuracy. The machine’s thermal stability further contributes to repeatable performance during extended machining cycles.

One of the key productivity advantages of the NHP 4000 is its dual-pallet automatic pallet changer. While machining operations continue on one pallet, operators can load and unload workpieces on the second pallet. This dramatically reduces non-cutting time and maximizes spindle utilization. The machine is also designed to integrate easily with pallet systems, robotic automation, and smart factory manufacturing environments.

Typically equipped with a high-speed direct-drive spindle, large-capacity automatic tool changer, Fanuc control system, and high-pressure coolant capability, the NHP 4000 is ideally suited for aerospace, automotive, defense, medical device, energy, industrial equipment, and precision contract manufacturing applications.

The 2020 DOOSAN NHP 4000 remains one of the most sought-after horizontal machining centers in the used CNC marketplace because it offers modern manufacturing technology, exceptional productivity, and strong long-term value.
