Pictured right: the second-generation DMU 60 eVo five-axis vertical machining centre from DMG MoriA second-generation DMU 60 eVo vertical-spindle, five-axis machining centre of swivelling rotary table design, having a thermo-symmetrical gantry configuration and optimised kinematics, has been introduced by Coventry-based
DMG Mori UK Ltd. The proven machine has been developed to meet increasing demands for precision, dynamics and flexibility, and utilises the manufacturer’s MX concept for process integration, automation, digital transformation and ‘green’ transformation.
The platform integrates various manufacturing processes including milling, turning at up to 1,200rev/min, gear skiving using a proprietary technology cycle, and grinding. Inclusion of these additional metalcutting possibilities transforms the production centre into a multifunctional machining solution that can be flexibly adapted to a range of requirements and industries. Various automation alternatives maximise machine utilisation, around the clock if required.
Compared to its predecessor, the machine has a working volume 40% larger at 750 x 550 x 550mm. Direct-drive ballscrews in the linear axes are standard, but linear motors are an option offering 80m/min rapid traverse. Table swivel range is generous at -5/+110deg and max table load has increased by 100kg to half a tonne. Steeply inclined, stainless steel interior surfaces and a 20% wider conveyor ensure optimum chip evacuation and reliable production.
Hybrid mineral castingThe machine bed is a hybrid mineral casting combining excellent stiffness, strength, vibration damping and thermal stability. Comprehensive cooling keeps critical components at a constant temperature. The second-generation DMU 60 eVo is also available in a µPrecision version, enabling it to machine the most demanding components to accuracies measured in low single figure microns.
The spindle portfolio includes versions capable of speeds up to 40,000rev/min or a torque of 200Nm. Tool storage with 30, 60 or 120 pockets is within the machine’s 9ft
2 footprint, which is 20% smaller than before. A double-chain magazine is also available for up to 300 tools. Thanks to an innovative tool exchange shutter, chip-to-chip time has been reduced by one sec to 4.5sec, further increasing machining efficiency.
Control options are the Siemens Sinumerik One or Heidenhain's TNC 7, with the DMG Mori Celos X graphical user interface and cloud-based software platform for data management. Automation can be provided by DMG Mori’s WH Cell workpiece handling system, Robo2Go Milling or PH Cell pallet handling arrangement.
