Overview

The DN Solutions DHF 8000 ST is a twin-pallet 5-axis horizontal machining center with a nodding A-axis spindle head, designed for multi-face machining of large, heavy workpieces. Unlike the DVF series that uses tilting tables, the DHF achieves its 5-axis capability through a nodding spindle head combined with a rotary B-axis table — an architecture that lets you keep heavy parts fixed while the spindle does the work.

Axis travel is substantial at 1,450 x 1,200 x 1,500 mm (57.1 x 47.2 x 59.1 in) on X/Y/Z. The 800 x 800 mm (31.5 x 31.5 in) twin pallets handle workpieces up to 2,000 kg (4,409 lb) each, putting this firmly in the heavy-part 5-axis territory that vertical machines can't reach. The twin-pallet system means you're loading the next part while the current one is cutting — critical for spindle utilization in production environments.

The spindle is a beast: 6,000 RPM with 35 kW (47 hp) and 960 Nm (708 ft-lbs) of torque through an HSK-T100 taper. That's serious material removal capability. At 960 Nm, you're pushing large face mills and heavy roughing endmills through cast iron, steel, and titanium without hesitation. The lower RPM reflects the heavy-cutting focus — this isn't a high-speed finishing machine, it's a chip-making workhorse.

Rapid traverse hits 40 m/min (1,575 ipm) on X and Y, jumping to 50 m/min (1,969 ipm) on Z — quick for a machine this heavy. The dual ball screw design on the main axes provides the feed force needed for heavy cuts while maintaining positioning accuracy. A central chip removal system handles the volume of chips this machine generates.

The 60-tool magazine provides enough capacity for most production jobs. At 31,000 kg (68,343 lb), you'll need solid floor preparation and proper rigging. The 11,835 x 5,830 mm (466 x 230 in) footprint is significant but reasonable for a twin-pallet HMC of this capability. The DHF 8000 ST competes with HMCs from Toyoda, Kitamura, and Okuma in the large-part 5-axis horizontal segment.

Strengths & Limitations

Strengths

960 Nm spindle torque through HSK-T100 provides massive material removal capability in steel, cast iron, and titanium
Twin-pallet system maximizes spindle utilization by loading/unloading during machining
2,000 kg pallet load capacity handles heavy workpieces that vertical 5-axis machines can't support
Nodding head 5-axis architecture keeps heavy parts fixed — no need to tilt massive workpieces
1,500 mm Z-travel is exceptional and accommodates deep-cavity and tall-part work
Dual ball screw design delivers the feed force and rigidity needed for aggressive roughing passes
Horizontal configuration provides natural chip evacuation away from the work zone

Limitations

6,000 RPM spindle speed limits surface speed for aluminum high-speed machining and fine finishing
31,000 kg machine weight and 11.8m footprint require significant floor space and foundation preparation
Twin-pallet system adds complexity and cost compared to single-table 5-axis alternatives
HSK-T100 tooling is expensive — holders and cutters cost significantly more than CAT 40 or HSK-A63 equivalents
Price point puts it in direct competition with established HMC platforms from Toyoda and Okuma

Best For

Heavy industry manufacturers machining large structural steel and cast iron components on multiple faces Aerospace production cells roughing titanium and Inconel parts that weigh up to 2,000 kg Automotive die and mold shops running large cavities that benefit from horizontal chip evacuation Energy sector operations machining turbine housings, valve bodies, and large pump components Production environments that demand high spindle utilization through twin-pallet operation Shops that need 5-axis access on heavy parts without the risks of tilting multi-ton workpieces

Frequently Asked Questions

01 What does the DN Solutions DHF 8000 ST cost?

New DHF 8000 ST pricing typically falls between $700,000 and $1,000,000 depending on configuration, automation level, and tooling package. Factor in an additional $50,000-$100,000 for HSK-T100 tooling investment and foundation preparation.

02 Why choose a nodding-head HMC over a tilting-table 5-axis?

When parts weigh 1,000+ kg, tilting them on a rotary table introduces dynamic loading issues and accuracy concerns. A nodding head keeps the heavy part fixed and moves the spindle instead. It's inherently more stable for heavy workpieces and provides better chip evacuation in the horizontal orientation.

03 How does the twin-pallet system work?

While one pallet is in the machining zone under the spindle, the other is in the load/unload position where the operator sets up the next part. When the cycle completes, pallets swap automatically. This keeps the spindle cutting while you're loading — spindle utilization rates above 85% are achievable.

04 Can the DHF 8000 ST do simultaneous 5-axis contouring?

Yes. The nodding A-axis head combined with the rotary B-axis table provides full simultaneous 5-axis capability. The machine handles complex contouring paths on large parts, though its primary strength is multi-face positioning and heavy-duty roughing rather than precision micro-contouring.
