Overview

The DN Solutions NHP 4000 is a high-performance 400mm-pallet horizontal machining center that puts speed first. With a 15,000 RPM spindle as standard, 60 m/min rapid traverse on all axes, and 30 kW (40 hp) of spindle power, it's built for shops that measure productivity in parts-per-hour, not inches-per-minute.

Axis travels span 560 x 640 x 660 mm (22 x 25 x 26 in) with an ISO 40 taper spindle delivering 230 Nm of torque. That's less torque than the NHC 4000's 353 Nm, but the NHP makes up for it with speed. The 15,000 RPM spindle and 60 m/min rapids slash non-cutting time to the minimum, and the lighter spindle assembly accelerates and decelerates faster for tighter contouring.

The 400mm pallet handles workpieces up to 400 kg (882 lb) with a 40-tool magazine. At 9,700 kg (21,385 lb), the NHP 4000 is the lightest horizontal in the DN Solutions lineup, reflecting its speed-oriented design. Lighter mass means faster axis acceleration, which compounds into significant cycle time savings on parts with many features.

The NHP 4000 targets high-volume production of aluminum, brass, and lighter steel components — automotive parts, aerospace brackets, and medical components where every second of cycle time matters. If you're timing your horizontal in minutes and need it in seconds, the NHP 4000's speed advantage is the difference maker.

Strengths & Limitations

Strengths

15,000 RPM standard spindle with 30 kW power handles high-speed aluminum and mixed-material production
60 m/min rapids on all axes are 50% faster than the NHC 4000 — significant cycle time savings on multi-feature parts
9,700 kg lightweight design enables faster axis acceleration and deceleration for tighter contouring
ISO 40 taper keeps tooling costs manageable while delivering 230 Nm for moderate steel work
Compact footprint makes it viable for shops with limited floor space
Speed-oriented design cuts non-cutting time to the minimum for maximum throughput

Limitations

230 Nm torque is lower than the NHC 4000's 353 Nm — heavy roughing in cast iron may push the limits
400 kg pallet capacity limits workpiece size and weight
40-tool magazine is modest compared to the NHC 4000's 262-tool option
9,700 kg machine weight may show vibration at very aggressive cutting parameters in hard materials

Best For

High-volume aluminum production shops needing 15,000 RPM horizontal capability Automotive suppliers running fast-cycle parts in aluminum, brass, and lighter steels Aerospace subcontractors machining small structural brackets and fittings at high throughput Medical device manufacturers needing speed and multi-side access for small components Production shops where cycle time reduction directly impacts profitability Shops that prioritize speed over heavy-cut torque in their part mix

Frequently Asked Questions

01 What does a DN Solutions NHP 4000 cost?

New NHP 4000 machines sell for $300,000 to $450,000. The premium over the NHC 4000 reflects the 15,000 RPM spindle, 60 m/min rapids, and speed-optimized machine structure.

02 How does the NHP 4000 compare to the NHC 4000?

The NHP 4000 has almost twice the rapids (60 vs implied ~30 m/min), a faster spindle (15,000 vs 8,000 RPM base), and more spindle power. The NHC 4000 offers more torque (353 vs 230 Nm) and expandable tool capacity up to 262 tools. Choose the NHP for speed; the NHC for torque and flexibility.

03 Is the NHP 4000 good for steel cutting?

It handles mild steel and medium-hard steels fine with 230 Nm of torque and 30 kW of power. But for aggressive roughing in cast iron or hardened steel with large-diameter cutters, the NHC 4000's higher torque or the NHM 5000's 50-taper spindle are better choices.

04 Can the NHP 4000 be automated?

Yes. The NHP series supports dual-pallet APCs and pallet pool automation. With 60 m/min rapids and 15,000 RPM, the NHP 4000 makes particularly good use of automation since its fast cycle times mean more pallet changes per shift.
