Overview
The DMG Mori DMU 65 H monoBlock is a unique horizontal-spindle variant of the popular DMU 65 monoBlock 5-axis platform, designed for shops that need horizontal chip evacuation and gravity-assisted chip flow combined with 5-axis capability. The horizontal spindle orientation means chips fall away from the workpiece rather than collecting in cavities, making it ideal for deep-cavity work in steel and cast iron.
Travel sits at 735 x 650 x 560 mm (28.9 x 25.6 x 22.0 in) with A-axis tilt of -5 to +110 degrees and 360-degree continuous C-axis rotation. The speedMASTER spindle runs at 12,000 RPM through a CAT 40 (HSK-A63 optional) taper, producing 22 kW (30 hp) and 157 Nm (116 ft-lb) of torque. Higher-speed spindle options up to 20,000 RPM are available for aluminum and composites work.
The monoBlock one-piece casting delivers exceptional rigidity for its size class. Tool storage holds 30 tools standard expandable to 60 or 120 positions. Maximum table load is 600 kg (1,322 lb). Running on CELOS with Fanuc or Siemens control.
The DMU 65 H monoBlock competes in a niche market with few direct competitors -- most shops choose between vertical 5-axis and horizontal 4-axis machines. New machines price between $375,000 and $525,000. Shops machining deep-cavity mold components, aerospace housings, and complex prismatic parts benefit from the combination of horizontal chip flow and full 5-axis capability.

Strengths & Limitations
Strengths
- Horizontal spindle orientation provides gravity-assisted chip evacuation for deep-cavity work in steel and cast iron
- Full 5-axis simultaneous capability with A/C rotary axes on a horizontal platform is rare in this class
- monoBlock one-piece casting delivers exceptional rigidity for its footprint
- Multiple spindle options from 12K to 20K RPM cover steel through aluminum applications
- CELOS available with Fanuc or Siemens control to match existing shop standardization
- Compact footprint compared to typical horizontal machining centers with similar capability
Limitations
- 30-tool standard magazine is limited for complex multi-operation parts requiring many tools
- No pallet changer standard -- single-table setup requires manual workpiece loading between cycles
- 735 x 650 x 560 mm travel is modest compared to dedicated horizontal machining centers
- Niche machine with limited resale market compared to mainstream HMC or 5-axis VMC platforms

Frequently Asked Questions
01
New machines price $375,000-$525,000 depending on spindle selection, ATC, and control choice. Used units are relatively rare on the secondary market.
02
The H variant has a horizontal spindle for gravity-assisted chip evacuation, making it better for deep-cavity work in steel and cast iron. The standard vertical DMU 65 monoBlock is more common and better for general 5-axis work.
03
No, the DMU 65 H monoBlock is a single-table machine. For horizontal machining with pallet changers, look at the NHX series.
04
CELOS with either Fanuc 31i-B5 or Siemens 840D sl, giving shops the flexibility to match existing control standardization.
