DMG Mori DMF 260

The DMG MORI DMF 260 is a long-bed machining center whose listed table measures 2,600 × 900 mm (102.4 × 35.4 in) and carries 6,000 kg (13,228 lb). Listed travels are 2,600 mm (102.4 in) in X, 1,100 mm (43.3 in) in Y and 900 mm (35.4 in) in Z. The model is absent from DMG MORI's current lineup and may be an older one, so use the listed figures to shortlist a machine and its own paperwork to decide.

The table is nearly three times as long as it is wide, and X travel covers its whole length. That geometry is for long, slender work: beams, rails, extrusions and mould plates, or a line of smaller parts in fixtures. At 6,000 kg the table load allows for steel parts of that length together with their fixtures. Y at 1,100 mm reaches past the table width, which helps with overhanging parts and with tool clearance at the table edges.

The spindle is listed at 8,000 rpm with 37 kW (49.6 hp) and 400 Nm, and rapid traverse at 30 m/min in X, Y and Z. On a 2,600 mm axis that rapid rate means an end-to-end move takes several seconds, so cycle time on long parts depends on how the operations are ordered. The magazine holds 40 tools as standard, with 80 or 120 tools listed as options. The spindle taper should be established on the machine itself before tooling is planned.

Positioning accuracy is listed as ±0.008 mm and the control as CELOS with Siemens 840D sl or FANUC 30i on a 21.5-inch ERGOline panel. The listed weight is about 50,000 kg (110,231 lb); confirm it before arranging transport and a foundation.
