Thermally Stable Machining Centre For Larger Workpieces

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 three tonnes, sits between the successful 1450 model and the company's DMF range of travelling column machines.

A one-piece cast iron bed, twin ballscrews in all axes, comprehensive cooling measures and linear scale positional feedback to the Siemens 840D solutionline or Heidenhain TNC 640 control with proprietary CELOS interface combine to deliver high stability and extreme accuracy, including circularity of less than five microns. The machine is thus particularly well suited to mould making and production of high precision aerospace parts.

There is a choice of spindle with 15,000, 20,000 or 40,000 rpm maximum speed or an optional SK 50 / HSK-A100 spindle offering up to 288 Nm of torque. Standard tool magazine capacity is 20 pockets, which may be expanded to 120 if desired. Maximum tool length is 400 mm. Short non-cutting times result from automatic tool change in under one second and acceleration in all axes at 5 m/s² to 42 m/min rapid traverse rate.

Ergonomic operation is another feature of the machine, thanks to a door that opens to nearly two metres 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 degrees, which together with efficient flushing ensures that chips are removed efficiently.
