DMC 55 duoBLOCK features Heidenhain control

Compared to its predecessor, the DMC 50H, the DMC 55H duoBLOCK horizontal machining centre occupies 30 per cent less space despite its larger machining chamber.

The DMC 55H duoBLOCK is optimised for the high demands of flexible batch production and takes pallet sizes up to 400 mm x 400 mm. The rigidity and stability of this machine are fully exploited by a large but accessible 560 mm x 600 mm x 600 mm machining chamber that acepts workpieces up to 500 kg. Positioning accuracy to ± 3 µm and repeatability of ±1 µm feature, supported by glass scales, a standard feature. A 12,000 rpm motor spindle reaches maximum speed after just 1.4 seconds is fitted as standard; delivering 110 Nm and 20 kW; an 18,000 rpm spindle is optional. Rapid traverses up to 80m/min., axes acceleration up to 1g and short chip-to-chip times as low as 2.8 seconds are other features. A servo-driven pallet hanger is on the side of the machining chamber and operates at various speed profiles dependent on workpiece weight. The machine can also be specified with the best tooling system for the job. The standard model comes with a turret for 45 tools weighing up to 10 kg and measuring up to 160 mm in diameter and 400 mm in length. Alternatively the DMC 55H duoBLOCK may be specified with the new high capacity vertical magazine with fast changer. Holding a maximum of 180 tools, this magazine accommodates tools up to 12 kg in weight with dimensions of 450 mm x 160 mm. To aid swarf evacuation, the machine features steep z-axis covers in the machining chamber and a powerful chip conveyor. In addition to the high-end Siemens SolutionLine control, the DMC 55H duoBLOCK may also be specified with the Heidenhain iTNC 530, the first of the DMG horizontal machining centres to offer this option.
