USED DOOSAN NHP 4000 – 2024

The DOOSAN NHP 4000 – 2024 is a next-generation horizontal machining center engineered for manufacturers seeking maximum productivity, automation compatibility, and precision machining performance. As part of Doosan’s advanced NHP Series, the NHP 4000 represents a significant evolution in horizontal machining technology, combining high-speed machining capabilities with exceptional rigidity, thermal stability, and smart manufacturing integration.

Designed for modern production environments, the NHP 4000 features a compact footprint while delivering the performance expected from a premium horizontal machining center. The machine is built around a heavily ribbed cast iron structure that minimizes vibration and maintains accuracy during aggressive cutting operations. This robust construction enables the machine to efficiently handle both high-speed aluminum machining and heavy-duty steel cutting applications.

One of the primary advantages of the NHP 4000 is its horizontal spindle design. Unlike vertical machining centers, chips naturally fall away from the cutting zone, improving chip evacuation and reducing heat accumulation around the workpiece. This results in improved surface finishes, longer tool life, and greater machining consistency, especially during extended production runs.

The machine incorporates a dual-pallet automatic pallet changer that allows loading and unloading operations to occur simultaneously with machining. This dramatically reduces idle time and increases spindle utilization, making the NHP 4000 particularly attractive for high-volume manufacturing operations. Combined with fast rapid traverses, a high-speed spindle, and a large-capacity tool changer, the machine delivers exceptional cycle time performance.

Typically equipped with advanced Fanuc control technology, high-pressure through-spindle coolant, and extensive automation capabilities, the NHP 4000 is well suited for integration into automated manufacturing cells and Industry 4.0 production environments.

Industries utilizing the NHP 4000 include aerospace manufacturing, automotive production, defense manufacturing, medical equipment production, energy sector manufacturing, semiconductor equipment manufacturing, and precision contract machining. Common applications include transmission housings, hydraulic manifolds, aerospace structural components, valve bodies, pump housings, gearbox cases, engine components, and complex multi-sided production parts.

The 2024 DOOSAN NHP 4000 remains one of the most advanced horizontal machining centers available in the used CNC market, offering modern technology, exceptional productivity, and long-term manufacturing flexibility.
