Based on the robust, proven design of DMG Mori’s DMV three-axis vertical machining centres, the manufacturer, which is reprsented in the UK by Coventry-based
DMG Mori UK Ltd, has developed the new DMX 60 U and DMX 80U for high-performance five-sided machining of workpieces weighing up to 300 and 350kg respectively.
With travels of 600 x 600 x 510mm for the DMX 60 U and 800 x 600 x 510mm for the larger model, the competitively-priced, three- plus two-axis machining centres with their swivelling rotary table are ideal for producing complex components. The machines both feature a design based on a monolithic machine bed and massive castings, providing up to 50% higher static rigidity compared to their predecessors. Combined with wide roller guideways in all axes, it ensures excellent stability during operation.
The design also enables dynamic machining and rapid traverse rates of up to 42m/min, 40% faster than predecessor machines. The speed of the rotary B-axis and C-axis for positioning parts has been raised by an even higher percentage, from 6rev/min to 10rev/min. Comprehensive, multi-sensor temperature compensation ensures thermal stability and hence consistently precise production, while direct drives and linear scales in the X and Y axes guarantee high-positioning accuracy.
The energy-efficient production centres are suitable for an extensive variety of applications thanks to the availability of a choice of spindles, starting with the 12,000rev/min inlineMASTER spindle as standard. SpeedMASTER spindles with a high torque of up to 200Nm or a speed of 20,000rev/min are optionally available.
The standard BIG PLUS face-and-taper toolholding interface provides additional stability and accuracy during machining. Different tool magazine options are available having from 30 to 120 pockets. DMG Mori has developed the new DMX U models with process integration in mind. For example, users can integrate grinding into the working area to avoid the need for an additional machine and a subsequent operation.
The manufacturer’s own Robo2Go Milling and MATRIS Light component handling solutions, as well as the PH 150, PH Cell 300 and PH Cell Twin pallet handling systems, enable flexible, automated operation including during unattended shifts. At the same time, the CELOS X app-based user interface on a Siemens Sinumerik ONE or a Heidenhain TNC7 CNC system creates the perfect platform for digital processes.
DMG Mori has equipped the two machines with ‘GreenMode’, with the objective of making production as ecologically friendly and economical as possible. Energy-efficient components and intelligent control reduce energy consumption by 10% compared with previous generation machines.
