USED DOOSAN NHP 4000 2017
The DOOSAN NHP 4000 2017 is a high-productivity CNC horizontal machining center designed for fast, accurate, and efficient machining of medium-sized components. The NHP 4000 uses a horizontal spindle arrangement, twin-pallet configuration, high-speed linear axes, and an automatic tool changer to reduce non-cutting time and support continuous production.
The machine provides approximately 560 mm X-axis travel, 640 mm Y-axis travel, and 660 mm Z-axis travel, with two 400 × 400 mm pallets. A typical configuration uses a 15,000 RPM, 30 kW spindle, CAT 40 tooling, and a 60-tool automatic tool changer. The machine can also be equipped with a full fourth axis, through-spindle coolant, probing, laser tool measurement, and chip conveyors.
The NHP 4000 is particularly attractive for manufacturers requiring high-volume production, short cycle times, and reliable machining of complex components. Its horizontal configuration also helps with chip evacuation, while the pallet changer allows one pallet to be loaded while the other is being machined.

The DOOSAN NHP 4000 2017 is an excellent choice for manufacturers that need high production output from a relatively compact horizontal machining center.
Its 15,000 RPM spindle, rapid axis movement, fast automatic tool changer, and two-pallet system are designed around minimizing non-cutting time. The horizontal spindle configuration also provides effective chip evacuation, which can be beneficial during heavy or continuous machining.
The machine’s 400 × 400 mm pallets provide a practical work area for small- and medium-sized components, while the optional full fourth axis can provide additional machining flexibility.
WHY BUY USED DOOSAN NHP 4000 2017
Buying a used DOOSAN NHP 4000 2017 can provide manufacturers with access to a highly productive horizontal machining center without the investment required for new equipment.
A properly maintained NHP 4000 can provide strong production capability, particularly for manufacturers running repetitive components where automatic pallet changing and fast tool changes can significantly reduce idle time.
Before purchasing a used NHP 4000, buyers should inspect the spindle, spindle bearings, CAT 40 taper, ballscrews, linear guideways, pallet changer, pallet positioning system, automatic tool changer, FANUC control, fourth axis if equipped, coolant system, chip conveyor, lubrication system, and electrical cabinet.
A complete test should include spindle operation, axis movement, pallet changing, tool changes, fourth-axis operation if equipped, coolant operation, and a test cut to verify positioning accuracy, repeatability, surface finish, and overall machine performance.
HOW MUCH DOES A USED DOOSAN NHP 4000 2017 COST?
The price of a used DOOSAN NHP 4000 2017 depends on spindle hours, machine condition, tool capacity, pallet system, fourth-axis equipment, CNC control, coolant package, probing, chip conveyor, tooling, and maintenance history.
A typical used machine may fall within the $75,000 to $125,000 USD range, although actual market value can vary significantly depending on configuration, condition, location, and included equipment.
Machines equipped with 60-tool capacity, full fourth axis, 1,000 PSI through-spindle coolant, Renishaw probing, laser tool setting, chip conveyor, low cutting hours, and documented maintenance history can command higher prices.
When evaluating the final purchase price, buyers should carefully assess the condition of the main spindle, pallet changer, pallet positioning, ballscrews, linear guides, automatic tool changer, FANUC control, fourth axis, coolant system, chip conveyor, electrical components, tooling, and overall machine accuracy.
