DMG Mori DMV 60

The DMG MORI DMV 60 is a fixed-table vertical machining center with a square working plan: 600 mm (23.6 in) of travel in both X and Y, and 510 mm (20.1 in) in Z. On that small plan it accepts workpieces up to 1,000 kg (2,204.6 lb), and the ratio of weight to size says what the machine is for. DMG MORI names die and mold work, where a compact steel block is heavy for its dimensions.

Because the table does not move, the axes carry the same mass whether the part weighs a few kilograms or the full 1,000 kg. DMG MORI states a constant dynamic characteristic regardless of the workpiece weight. In practice, feeds and accelerations proven on a light electrode still hold on a heavy insert. The structure is a monolithic machine bed with wide roller guideways in all axes, and static rigidity is given as 40% higher than that of the predecessor.

Three spindles are named, all with the BIG PLUS interface: an inlineSPINDLE at 12,000 rpm, a speedMASTER High Torque at 15,000 rpm and a speedMASTER at 20,000 rpm. The Highlights give speeds only, with no power or torque, so compare the torque curves on the quotation. As a rule the 20,000 rpm spindle belongs to finishing hardened steel with small ball-nose cutters, and the slower ones to roughing and general milling.

Linear scales are fitted in all linear axes, X and Y have direct drive transmission, and circular interpolation measured by ball-bar is under 6 µm in all planes. Rapid traverse is 42 m/min in all linear axes.

Workpiece size is limited to 900 × 600 × 550 mm (35.4 × 23.6 × 21.7 in). Longer parts move up the series: the DMV 110 has 1,100 mm (43.3 in) of X on the same Y and Z, and the DMV 145 has 1,450 mm (57.1 in), 700 mm (27.6 in) and 550 mm (21.7 in).
