Overview

The DMG Mori DMC 340 u FD is the flagship of DMG Mori's portal 5-axis mill-turn platform, delivering the largest work envelope in the rotary-table portal lineup at 3,400 x 3,400 x 2,000 mm (133.9 x 133.9 x 78.7 in). This machine handles workpieces up to 3,400 mm (133.9 in) diameter, 1,960 mm (77.2 in) height, and 10,000 kg (22,046 lb), making it one of the most capable single-spindle 5-axis platforms available from any manufacturer.

The portal gantry construction provides the structural integrity needed to maintain cutting accuracy across a 3.4-meter travel cube. The powerMASTER motor spindle delivers 1,000 Nm (738 ft-lb) through HSK-A100, while the torqueMASTER gear spindle option pushes to 1,800 Nm (1,328 ft-lb) for maximum roughing performance. The DirectDrive table provides 10,200 Nm (7,523 ft-lb) of torque for turning operations on the heaviest workpieces.

Feed speed reaches 60 m/min (2,362 ipm) across all axes. The tool magazine holds up to 243 tools in the wheel configuration. A 2,500-liter band filter coolant system comes standard, providing the volume needed for sustained heavy machining on massive workpieces. Control options are SIEMENS SINUMERIK ONE or HEIDENHAIN TNC7 with CELOS X.

At this scale, the DMC 340 u FD competes directly with dedicated gantry machines, but offers the advantage of a rotary table for combined milling, turning, and grinding in one setup. Workpieces that would require two or three separate machines -- a gantry mill, a vertical turning lathe, and possibly a grinding machine -- can be completed on the DMC 340 u FD in a single setup, eliminating the accuracy risks and handling costs of transferring 10-ton workpieces between machines.

Strengths & Limitations

Strengths

3,400 x 3,400 x 2,000 mm travel is among the largest available in a rotary-table 5-axis portal, handling extreme-scale workpieces
10,000 kg table load accommodates the heaviest forgings, castings, and structural components in aerospace and power generation
10,200 Nm DirectDrive table torque enables heavy turning on the largest diameters without a dedicated vertical turning lathe
Combined milling, turning, and grinding in one setup eliminates handling and accuracy risks of transferring 10-ton workpieces
Portal construction maintains symmetric rigidity across the 3.4-meter travel cube
2,500-liter coolant system provides the volume for sustained heavy machining on massive components

Limitations

Price above $4M makes this one of the most expensive single-spindle machine tools available, requiring extreme-scale production to justify
Installation requires a purpose-built facility with deep foundation pit, overhead crane capacity, and climate control -- total installed cost adds $300,000-$700,000+
Very few shops have consistent workpiece volume at this scale to achieve acceptable utilization rates
243-tool magazine may require supplementary tool loading for complex multi-feature parts at this scale
Lead times of 18-24+ months from order to production are typical for this machine class

Best For

Aerospace OEMs machining the largest engine casings, structural bulkheads, and landing gear components in titanium and Inconel Power generation manufacturers machining large gas and steam turbine casings, generator housings, and compressor diaphragms Oil and gas manufacturers producing the largest subsea and wellhead equipment requiring combined 5-axis mill-turn Defense contractors machining large naval propulsion and submarine components Shops consolidating large gantry mill, vertical turning lathe, and grinding operations into a single platform

Frequently Asked Questions

01 What does a DMG Mori DMC 340 u FD cost?

New machines typically price between $4,000,000 and $6,000,000 depending on spindle, accuracy packages, tool magazine, and automation. Foundation and installation add $300,000-$700,000+. Total project cost including tooling, training, and commissioning can approach $7M.

02 DMC 340 u FD vs dedicated gantry machine -- which is better?

The DMC 340 u FD offers the unique advantage of a rotary table for combined milling, turning, and grinding -- capabilities no gantry machine provides. Dedicated gantry machines offer longer X-travel for very long parts. For workpieces requiring rotational features, the DMC 340 u FD eliminates multi-machine transfers.

03 What is the realistic installation timeline?

Plan for 18-24 months from order to production. Foundation design and construction should start 6-9 months before machine arrival. Rigging, installation, and commissioning take 4-8 weeks depending on configuration complexity.

04 What workpiece handling is needed for 10-ton parts?

Shops need overhead crane capacity of at least 15-20 tons (includes fixtures) with sufficient hook height and reach to load the machine. Pallet changer systems and automated loading solutions from DMG Mori help manage large workpiece handling safely.
