DMG Mori DMU 125 p FD duoBLOCK

Turning at up to 500 rpm on a DirectDrive table is what the DMG MORI DMU 125 p FD duoBLOCK adds to a large 5-axis machine. Milling and turning happen in one setup, on parts up to 1,250 mm (49.2 in) in diameter, 1,600 mm (63 in) in height and 2,800 kg (6,172.9 lb), within travels of 1,250 × 1,250 × 1,000 mm (49.2 × 49.2 × 39.4 in).

The case for a machine like this is the part that would otherwise visit a vertical lathe and then a machining center. A large bearing housing, a casing or a ring can have its bores and faces turned, and its bolt circles, ports and pockets milled, from one set of datums. DMG MORI also lists grinding as an integrated technology, so a bearing seat or sealing face can be finished without a move to a grinder. The listed data gives the table speed only; table torque for turning and any turning-specific weight limit are not published.

Milling is covered by two spindles. The powerMASTER motorspindle has 737.6 ft lb and 103.3 hp. The 5X torqueMASTER has 1,327.6 ft lb and 69.7 hp. No speed appears for either. A roughing package is quoted with up to 50 % higher cutting power.

Because turning tools, milling tools and grinding wheels all draw on the same magazine, its size matters more here than on a pure milling machine. The wheel magazine is listed with 453 tool pockets and a tool replenishment time of max. 5.6 sec. For thermal stability across long combined cycles the feed drive is completely water-cooled and a spindle growth sensor (SGS) compensates for spindle growth. Availability is stated as 96 %.
