Overview

The DN Solutions NHP 5500 2ND is the second-generation evolution of DN Solutions' mid-range horizontal machining center, built for shops that need more muscle than a 400mm-class HMC but don't want the footprint or cost of an 800mm platform. The "2ND" designation means this is a ground-up redesign incorporating thermal compensation improvements, structural refinements, and updated control integration that the first generation lacked.

The spindle runs an ISO 50 taper at 10,000 RPM standard (15,000 RPM optional) with 37/26 kW (50/35 hp) and dual torque ratings of 516/644 Nm. That ISO 50 taper is the key differentiator from the NHP 5000 — it lets you run larger face mills, bigger endmills, and push heavier cuts in steel and cast iron without worrying about taper deflection. For shops cutting a lot of ferrous material, that matters more than spindle speed numbers.

Axis travels of 800 x 750 x 900 mm (31 x 30 x 35 in) give you a generous work envelope relative to the 500 x 500 mm pallet size. The 800 kg (1,764 lb) pallet load capacity handles substantial tombstone setups and heavy workpieces. Rapid traverse stays at 60 m/min across all axes — that's top-tier for an ISO 50 machine and keeps cycle times competitive with lighter, faster platforms. At 14,000 kg, this machine has the thermal mass and structural rigidity to hold tight tolerances through three-shift production. The 40-tool standard magazine covers most jobs, with expansion options available for complex parts.

Strengths & Limitations

Strengths

ISO 50 taper with 644 Nm torque handles heavy roughing in steel and cast iron that ISO 40 machines can't match
60 m/min rapid traverse is exceptionally fast for an ISO 50 HMC, keeping non-cutting time competitive with lighter platforms
800 kg pallet load capacity accommodates heavy tombstones and large steel workpieces without compromise
Second-generation design incorporates improved thermal compensation and structural refinements over the original NHP 5500
15,000 RPM optional spindle bridges the gap between heavy cutting and high-speed finishing in a single setup
900 mm Z-travel provides excellent reach for deep features and tall fixture setups

Limitations

14,000 kg machine weight requires solid floor preparation and may need foundation work in some facilities
ISO 50 tooling costs more than ISO 40, and the holders are heavier for operators to handle
Base price premium over ISO 40 HMCs like the NHP 5000 may not be justified for primarily aluminum work
40-tool standard magazine fills up fast with complex multi-operation parts — budget for the expansion option

Best For

Production shops cutting primarily steel and cast iron that need the rigidity and torque of an ISO 50 platform Heavy equipment and energy sector manufacturers running large, heavy workpieces on tombstone fixtures Shops that outgrew their 400mm-class HMC but don't need an 800mm platform yet Multi-shift production environments where thermal stability and consistent accuracy matter around the clock Job shops handling a wide material mix that benefits from the ISO 50's versatility across steel, iron, and aluminum

Frequently Asked Questions

01 What does a DN Solutions NHP 5500 2ND cost?

New NHP 5500 2ND machines run $320,000-$480,000 depending on configuration. The base machine with 10,000 RPM spindle, 40-tool ATC, and dual-pallet changer starts around $320,000-$370,000. Adding the 15K RPM spindle, expanded tool magazine, through-spindle coolant, and probing pushes pricing to $400,000-$480,000.

02 How does the NHP 5500 2ND compare to the NHP 5000?

The fundamental difference is the ISO 50 taper versus ISO 40. The NHP 5500 2ND delivers nearly three times the spindle torque (644 Nm vs 230 Nm), handles heavier pallet loads (800 kg vs 500 kg), and runs bigger cutters. The NHP 5000 wins on spindle speed (15K-20K RPM vs 10K-15K). Choose the 5500 for ferrous metals and heavy cutting; choose the 5000 for aluminum and high-speed work.

03 What's the advantage of the second-generation design?

The 2ND generation brings improved thermal management with enhanced coolant circulation through the spindle and casting, refined structural ribbing for better vibration damping, and updated FANUC 0i-Plus control integration with iHMI touchscreen. It's a meaningful upgrade over the first-gen NHP 5500 in both accuracy retention and operator experience.

04 Can the NHP 5500 2ND handle aerospace materials?

Yes. The high torque handles titanium and Inconel roughing effectively, and the 15K RPM optional spindle provides the speed needed for aluminum structural parts. The 60 m/min rapids keep cycle times competitive. It's not a dedicated aerospace cell machine like a Makino T-series, but it handles most aerospace materials well in a production setting.
