DMG Mori DMU 160 P duoBLOCK

The DMG Mori DMU 160 P duoBLOCK is the flagship of the duoBLOCK 5-axis series, built for shops that machine the largest and heaviest workpieces that fit on a rotary-table 5-axis platform. With 1,600 x 1,600 x 1,100 mm (63 x 63 x 43.3 in) of travel and a 4,500 kg (9,921 lb) table load capacity, this machine handles large aerospace structural components, heavy mold bases, and power generation parts that would overwhelm smaller platforms.

The massive work envelope accommodates parts up to 1,600 mm (63 in) in diameter and 1,775 mm (69.9 in) in height. That covers large turbine casings, structural aircraft components, and full-size injection mold halves in a single setup. The B-axis swivels through 210 degrees (-30 to +180), and the C-axis provides 360-degree continuous rotation through direct-drive motors for backlash-free positioning.

Spindle options follow the duoBLOCK standard. 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 maxes out at 1,300 Nm (1,328 ft-lb) at 52 kW (70 hp) for heavy roughing in titanium and Inconel. The FD mill-turn variant adds direct-drive table rotation up to 400 RPM, slightly lower than smaller duoBLOCK models due to larger table mass.

The duoBLOCK construction is most impressive in the 160 P. Thermosymmetric castings with three guide ways on the Y-axis provide the mass and rigidity to keep vibration in check during aggressive interrupted cuts on large workpieces. Water-cooled feed drives on all linear axes and the Spindle Growth Sensor maintain thermal stability through extended roughing cycles.

Tool magazine capacity reaches 453 pockets with 5.6-second chip-to-chip changes. Both SIEMENS SINUMERIK ONE and HEIDENHAIN TNC7 controls run CELOS X with integrated process monitoring. DMG Mori quotes 96% uptime for the platform.

For shops machining parts in the 1-4 ton range that require simultaneous 5-axis capability, the DMU 160 P duoBLOCK sits in a class with very few competitors. The combination of 4,500 kg table load, 1.6-meter travel cube, and duoBLOCK rigidity makes this the machine for large-part 5-axis work. Specs sourced from DMG Mori published data.
