Machining centre with universal appeal

Said to be universally applicable across the aerospace, mechanical engineering and mould and die sectors, DMG Mori has released its DMU 340 Gantry machining centre. The machine has a one-piece, thermo-symmetrical EN-GJS-600 cast-iron machine bed accommodating a working volume of 3400 x 2800 x 1250 mm, which is expandable to 6000 mm in the X axis and 1500 mm in Z.

Linear drives in the X and Y axes offer up to 0.5 G acceleration and (optionally) 90 m/min rapid traverse rates. The drives combine with a ram featuring an integrated, direct-drive C axis, as well as a B-axis milling head with direct drive and 50° swivel, to provide a fully interpolative five-axis machining platform for producing large, complex components. According to DMG Mori, the machine achieves surfaces finishes down to Ra 0.3 µm.
The standard machine version with 4400 x 2700 mm table accommodates workpieces weighing up to 10,000 kg, although the maximum load can be trebled on request.
A range of HSK-A63 and HSK-A100 motor spindles, manufactured in-house, is available rated up to 30,000 rpm (or 79 kW or 430 Nm). The SK40-SpeedMaster with 15,000 rpm and 130 Nm is standard. There is space for 30 tools in the chain magazine, although an optional wheel magazine can accommodate 63 tools, extendable up to 183 pockets.
DMG Mori deploys its CELOS app-based control and operating interface to a Siemens or Heidenhain CNC system. An Industry 4.0-ready interface, which is compatible with ERP systems and can be linked to CADCAM applications, integrates the machine into a customer’s production environment.
