Universally capable

A powerful, dynamic, compact machining centre said to be universally applicable across the aerospace, mechanical engineering and die and mould sectors has been introduced by DMG Mori.

The DMU 340 Gantry has a stable, one-piece, thermo-symmetrical EN-GJS-600 cast iron machine bed featuring comprehensive cooling for high rigidity and accuracy. Working volume is 3,400 x 2,800 x 1,250mm, expandable to 6,000mm in the X-axis and 1,500mm in Z.

Linear drives in the X- and Y-axes with up to 0.5g acceleration and optionally 90m/minute rapid traverse, plus a ram with integrated, direct drive C-axis and a B-axis milling head with direct drive and 50° swivel combine to provide a highly productive, fully interpolative 5-axis machining platform for producing large, complex components.

Markus Piber, managing director of the Deckel Maho factory in Pfronten, Southern Germany comments: "The maintenance-free linear drives provide long-term precision and high dynamics for elevated levels of productivity and excellent control over quality. Coupled with their rigidity, the machines achieve surfaces finishes down to Ra 0.3µm."

The standard machine version with 4,400 x 2,700mm table accommodates workpieces weighing up to 10 tonnes, although the maximum load can be trebled on request.

An extensive range of HSK-A63 and HSK-A100 motor spindles, manufactured in-house, is available rated up to 30,000rpm or 79kW or 430Nm. The SK40-SpeedMASTER with 15,000rpm and 130Nm is standard. There is space for 30 tools in the chain magazine although an optional wheel magazine can accommodate 63 tools, extendable to up to 183 pockets.

DMG Mori uses its Celos app-based control and operating interface to a Siemens or Heidenhain CNC system. It has a 21.5-inch, touchscreen display and 26 Celos apps to assist in scheduling work and optimising processes. The Industry 4.0-ready interface, which is compatible with ERP systems and can be linked to CAD/CAM applications, integrates machines into a manufacturer's production environment.
