DMG Mori DMU 75 monoBLOCK

Eight square metres is the number to start with on the DMG MORI DMU 75 monoBLOCK 2nd Generation: the footprint is 8 m² for a 5-axis machine that travels 750 × 650 × 560 mm (29.5 × 25.6 × 22 in) and accepts a workpiece 840 mm (33.1 in) in diameter. DMG MORI's Highlights call it the most compact machine, and the door opening of 1,310 mm is wide in proportion.

Loading is by crane where needed. The Highlights give crane loading of up to 600 kg, the same as the maximum workpiece weight of 600 kg (1,322.8 lb), so the heaviest permitted part can be lowered straight onto the table. Height is the tighter dimension: 500 mm (19.7 in) for the workpiece, on 560 mm of Z travel. With a part near that height, the tool length and the Z stroke left over for retracts should be checked in the interference drawing before the fixture is designed.

The diameter is bigger than both X and Y travel. That is usual for a table-type 5-axis machine, where features on the outer edge of a large part are brought to the spindle by the rotary axis. It does mean that a full-size part cannot be faced across its whole width in one pass at a fixed table position.

Under the enclosure the machine is one casting with a one-piece column and 45 mm roller guideways. Positioning accuracy is 4 µm as standard, and the coolant unit, cooling measures and multi-sensor compensation are standard items. The machine sets up on three points. Spindle and tool magazine figures are not part of the data listed for this model. The DMU 60 FD eVo 2nd Generation is a neighbour with the same 750 mm (29.5 in) of X but 550 mm (21.7 in) of Y and Z.
