Thermally stable machine for large parts

In terms of capacity, the new DMC 1850 V vertical machining centre from DMG Mori, with 1,850 x 700 x 550 mm axis travels and a maximum table load of 3000 kg, sits between the company’s 1450 model and the DMF range of travelling-column machines.

A one-piece cast-iron bed, twin ballscrews in all axes, a cooling system and linear scale positional feedback to the Siemens 840D or Heidenhain TNC 640 control with proprietary CELOS interface, combine to deliver accuracy that includes circularity of less than 5µm. The machine is thus suited to mould making and the production of precision aerospace parts.
There is a choice of spindle with 15,000, 20,000 or 40,000 rpm maximum speed or an optional SK50/HSK-A100 spindle offering up to 288 Nm of torque. The standard tool magazine capacity is 20 pockets, which may be expanded to 120 if desired, while the maximum tool length is 400 mm. Short non-cutting times result from automatic tool change in under one second and 5 m/s² acceleration in all axes to a rapid traverse rate of 42 m/min.
Ergonomic operation is another feature of the machine, thanks to a door that opens to nearly 2 m and a distance from the front of the machine to the centre of the 2,160 x 750 mm table of just 677 mm. The bed inclines steeply at 35°, which together with flushing ensures that chips are removed efficiently.
