Overview

The DMG Mori DMU 125 P FD duoBLOCK is the mill-turn variant of the DMU 125 P duoBLOCK, adding a DirectDrive rotary table capable of turning at up to 500 RPM to the large-format duoBLOCK platform. With 1,250 x 1,250 x 1,000 mm (49.2 x 49.2 x 39.4 in) of travel and a square X-Y footprint, this machine delivers combined 5-axis milling and turning for medium-to-large parts up to 2,600 kg (5,732 lb) in FD configuration.

The FD designation adds turning operations through a DirectDrive C-axis table spinning at up to 500 RPM, enabling facing, boring, and cylindrical turning without transferring the workpiece to a lathe. Standard table load is 2,800 kg (6,173 lb) in milling mode, dropping to 2,600 kg in FD turning mode — the highest FD table load in the mid-range duoBLOCK series.

The duoBLOCK construction provides the rigidity backbone: thermosymmetric casting design, three guide ways on the Y-axis, and water-cooled feed drives on all linear axes. This gives the DMU 125 P FD the structural integrity to sustain heavy cuts in both milling and turning modes without sacrificing accuracy. The B-axis swivels through 210 degrees (-30 to +180), and the C-axis provides 360-degree continuous rotation with direct-drive motors.

Spindle options mirror the duoBLOCK family. The powerMASTER 1000 motor spindle delivers 77 kW (103 hp) and 1,000 Nm (738 ft-lb) through HSK-A100. The 5X torqueMASTER gear spindle pushes to 1,300 Nm (1,328 ft-lb) at 52 kW (70 hp). Maximum workpiece diameter reaches 1,250 mm (49.2 in) with a height of 1,600 mm (63 in).

The tool magazine scales to 453 pockets with 5.6-second tool changes. Both SIEMENS SINUMERIK ONE and HEIDENHAIN TNC7 controls are available with CELOS X integration. For shops needing combined mill-turn capability with heavy table loads and a generous work envelope, the DMU 125 P FD duoBLOCK sits between the DMU 100 P FD and the massive DMU 160 P FD.

Strengths & Limitations

Strengths

2,600 kg FD table load is the highest in the mid-range duoBLOCK FD series for heavy-part turning operations
DirectDrive table at 500 RPM enables efficient turning of medium-to-large diameter features on heavy workpieces
Square 1,250 x 1,250 mm X-Y travel provides generous work envelope for large combined mill-turn components
PowerMASTER spindle at 103 hp and 1,000 Nm sustains aggressive milling between turning passes
DuoBLOCK construction with thermosymmetric castings delivers rigidity for combined milling and turning accuracy
453-tool magazine enables complex multi-operation mill-turn parts without operator intervention

Limitations

Price starting above $900K makes this a significant capital investment requiring strong utilization to justify
Table load drops from 2,800 kg to 2,600 kg in FD mode — modest reduction but limits the heaviest turning work
HSK-A100 tooling investment across milling and turning tool holders adds substantially to ownership cost
Combined mill-turn programming demands operators skilled in both disciplines
Larger footprint than the DMU 100 P FD requires more floor space and foundation engineering

Best For

Aerospace manufacturers machining large structural components with both milled contours and turned journals up to 2,600 kg Power generation shops producing large turbine components, impellers, and pump housings requiring mill-turn Mold and die manufacturers needing turned guides and milled cavities on heavy mold bases Heavy equipment manufacturers requiring 5-axis mill-turn capability for large steel and cast iron components Production environments where the DMU 100 P FD table load or work envelope has become a bottleneck

Frequently Asked Questions

01 What does a DMG Mori DMU 125 P FD duoBLOCK cost?

New DMU 125 P FD duoBLOCK machines typically run $900,000 to $1,400,000. The FD option adds approximately $75,000-$125,000 over the standard DMU 125 P. Full configuration with torqueMASTER spindle, 453-tool magazine, and automation approaches $1.4M.

02 How does the DMU 125 P FD compare to the DMU 160 P FD?

The DMU 160 P FD offers 28% more X/Y travel (1,600 vs 1,250 mm), 73% more table load (4,500 vs 2,600 kg in FD), but at $300,000-$400,000 more. Choose the 125 P FD when parts and fixtures stay under 2,600 kg; step up to the 160 P FD for the heaviest workpieces.

03 Is 500 RPM turning speed sufficient?

500 RPM is sufficient for facing, boring, and contour turning on parts from 200 mm to 1,250 mm in diameter. At 500 RPM on a 200 mm diameter, surface speed reaches approximately 314 m/min — adequate for steel turning. For smaller diameters requiring higher surface speeds, the DMC 80 u FD at 800 RPM is more suitable.

04 What automation options work with the DMU 125 P FD?

DMG Mori offers the PH Cell 300 and PH Cell 2000 pallet handling systems, linear pallet pool, and robotic loading. The 453-tool magazine combined with pallet automation enables extended unmanned mill-turn production.
