The 1,600 × 1,600 × 1,100 mm working range and 4,500 kg workpiece capacity are also consistent with DMG MORI's published data for the DMU 160 P duoBLOCK platform.

A comparable DMU 160 P duoBLOCK configuration with a 12,000 rpm spindle, SK50 taper, 1,600 / 1,600 / 1,100 mm travels and 60 m/min rapid traverse is currently documented on the used-machine market.

Important Configuration Note

The machine is identified as DMU 160 P duoBLOCK, not necessarily the FD mill-turn version. DMG MORI lists approximately 1,675 mm maximum workpiece height for the milling version, while the 1,775 mm specification applies to the FD configuration.

Key Selling Points

Large 5-Axis Machining Capacity
The 1,600 × 1,600 × 1,100 mm machining envelope makes the DMU 160 P duoBLOCK suitable for components that are too large for conventional 800 mm or 1,000 mm class 5-axis machining centers.

Heavy-Duty SK50 Spindle
The SK50 spindle interface is particularly attractive for larger cutters, deeper cuts and applications requiring higher rigidity than smaller SK40 or HSK63 configurations.

12,000 rpm Spindle Speed
The spindle provides a practical balance between heavy machining capability and finishing performance.

High Workpiece Capacity
Up to approximately 4,500 kg workpiece capacity allows machining of large housings, dies, structural components and heavy precision parts.

duoBLOCK Machine Structure
DMG MORI developed the duoBLOCK concept around rigidity, thermal stability and demanding 5-axis machining. The manufacturer specifically positions this platform for difficult-to-machine materials and applications ranging from aerospace to tool and mold production.

Measured Accuracy Data Available
Renishaw axis and rotary-axis measurements help overseas buyers evaluate the actual working condition of a used machine before making a purchasing decision.
