Overview
The DMG Mori DMU 340 P FD is the flagship of the P-series portal 5-axis line, representing DMG Mori's most capable tilting-head portal machine with integrated direct-drive turning capability. With 3,400 x 3,000 x 1,500 mm (133.9 x 118.1 x 59.1 in) of axis travel and a fixed table rated for workpieces up to 30,000 kg (66,139 lb), the DMU 340 P FD is built for aerospace prime contractors, large energy manufacturers, and defense programs that machine the most demanding large-structure components in serial or batch production.
The 3,400 mm X-travel is the defining specification of the 340 P platform. Aerospace structural programs routinely require single-setup machining of wing ribs, spar sections, and fuselage frames in this length class. Machining these parts in a single setup — rather than repositioning — is essential for maintaining the geometric relationships between features that assembly tolerances demand. The 340 P FD delivers that capability with 5-axis simultaneous contouring over the full 3.4-meter travel.
The FD (Functional Direct Drive) C-axis integrates direct-drive rotation into the fixed portal table. This enables turning operations on large ring components, cylindrical housings, and flanged parts directly on the portal machine, eliminating transfer to a separate turning center. For power generation components, large pump housings, and aerospace engine cases that require both extensive milled features and turned surfaces, the FD platform delivers done-in-one processing at this scale.
Spindle selection matches the demands of the work. The powerMASTER 1000 motor spindle delivers 77 kW (103 hp) and 1,000 Nm (737 ft-lb) of torque at up to 12,000 RPM through HSK-A100. The 5X torqueMASTER gear spindle reaches 1,800 Nm (1,328 ft-lb) for heavy roughing in titanium and Inconel. A high-speed electrospindle option supports finishing operations at elevated surface footage. Tool magazine capacity extends to 243 tools, enabling complete complex parts without manual intervention.
Positioning accuracy reaches 10 micrometers standard, with the accuracy pack option at 8 micrometers. Control is CELOS with Siemens SINUMERIK ONE or Siemens 840D solutionline. For programs requiring the combination of large 5-axis travel, extreme workpiece weight, and integrated turning, the DMU 340 P FD defines the top of the portal 5-axis category.

Strengths & Limitations
Strengths
- 3,400 mm X-travel is the longest in the P-series portal lineup, enabling single-setup machining of full-length aerospace wing structures and fuselage sections
- 30,000 kg fixed-table workpiece capacity matches the heaviest requirements of aerospace structural programs and energy sector components
- FD direct-drive C-axis enables turning of large ring components on the portal platform, eliminating inter-machine transfers for done-in-one processing
- 1,800 Nm torqueMASTER spindle torque delivers aggressive roughing capability in titanium, Inconel, and hardened steel at this scale
- 5-axis simultaneous contouring over the full 3.4-meter travel maintains the geometric precision that aerospace assembly tolerances require
- 243-tool magazine supports complex multi-operation aerospace and energy parts through complete unattended cycles
- SINUMERIK ONE with CELOS provides full digital twin capability and process monitoring for aerospace quality documentation requirements
Limitations
- Price range of $3M-$5.5M places this machine in a category where ROI requires continuous high-value aerospace or energy contracts
- 30-tonne workpiece capacity demands substantial crane infrastructure, floor loading analysis, and material handling investment
- Massive footprint exceeds 150 square meters including working clearances, requiring a dedicated manufacturing cell
- Lead time for new machines can exceed 18-24 months from order to delivery due to build complexity
- Foundation engineering is a major project in itself, typically adding $80,000-$200,000 to installation costs
- HSK-A100 tooling across 243 magazine positions represents a substantial tooling investment before first part

Frequently Asked Questions
01
New DMU 340 P FD machines typically run $3,000,000 to $5,500,000 depending on spindle selection, tool magazine configuration, accuracy packages, FD turning table specifications, and automation integration. Base powerMASTER configurations start at the lower end; fully configured machines with torqueMASTER, 243-tool magazine, accuracy pack, and automation approach the upper range.
02
The DMU 340 P FD extends X-travel from 2,700 mm to 3,400 mm and offers a larger overall work envelope for parts in the 3-4 meter class. Both share 30,000 kg workpiece capacity and FD direct-drive turning capability. Choose the 340 P FD when your parts consistently require more than 2,700 mm of travel.
03
FD stands for Functional Direct Drive. The FD configuration integrates a direct-drive C-axis rotary table into the fixed portal table structure, enabling turning operations on large cylindrical and ring-type workpieces. This eliminates the need to transfer large workpieces to a separate turning center after milling operations.
04
Yes. The 5X torqueMASTER spindle at 1,800 Nm is specifically configured for heavy roughing in titanium and titanium alloys. Combined with 50,000 N feed force and the thermosymmetric portal construction, the machine maintains aggressive metal removal rates in Ti-6Al-4V with controlled vibration through the full 3.4-meter travel.
05
A machine of this size and weight requires a purpose-engineered reinforced concrete foundation with precise leveling pads, vibration isolation, and floor loading calculations for both machine weight and maximum workpiece weight. Budget $80,000-$200,000 for foundation work and consult DMG Mori installation engineering early in the project planning phase.
