DOOSAN NHP 4000 HORIZONTAL MACHINING CENTER

Technical Description

The Doosan NHP 4000 is a compact horizontal machining center engineered for high-productivity metalworking applications. This machine features a robust travel envelope with X, Y, and Z-axis strokes of 22, 25.2, and 26 inches respectively, accommodating workpieces on a 15.75-inch square pallet configuration. The spindle delivers 15,000 RPM with 40.2 horsepower, providing sufficient cutting power for ferrous and non-ferrous materials. Equipped with a CAT 40 BP taper tool interface, the machine accommodates an impressive 275-tool capacity, enabling extended unmanned operation and minimizing tool-change downtime. The system employs a 12-pallet automatic changer with precise 1-degree indexing capability, facilitating seamless part loading and unloading while maintaining continuous machining cycles. This multi-pallet configuration substantially enhances production efficiency for batch and small-lot manufacturing. The machine's rigid casting construction ensures thermal stability and dimensional accuracy across extended production runs. Measuring 195 x 90.55 x 105.9 inches with a 9,700-pound footprint, the NHP 4000 balances compact floor space requirements with substantial machining capability. The combination of high-speed spindle performance, extensive tool storage, and multi-pallet automation makes this machine particularly suitable for job shops and contract manufacturers requiring flexible, efficient production of complex precision parts with minimal operator intervention.
