Having a rigid table measuring 2,300 by 850 mm and travels of 2,000 by 800 by 850 mm, the DMF 200|8 offers users in the aerospace and mould making industries, for example, scope to machine long components up to the maximum table load of 2,000 kg. Rapid traverse in the linear axes is 50 m/min as standard, but with an optional linear drive in the X-axis it reaches 80 m/min. Holistic cooling throughout the machine delivers long-term accuracy and tight tolerances.
The B-axis milling head with 6,000 Nm maximum clamping torque offers a swivel range of ± 120° for flexible 5-axis machining. A 15,000 rpm speedMASTER spindle is standard, while an extensive choice of other modular spindles is offered, including a 200 Nm high torque version and a 20,000 rpm high speed version. All are covered by a 36-month warranty, regardless of running hours.
The machine is equipped with a Siemens control and the latest version of DMG Mori's proprietary app-based user interface, CELOS. Users are well equipped for digitalised production and automation, for example by the attachment of the manufacturer's PH Cell automatic pallet changer.
During the development of the DMF 200|8, the working area was optimised through an innovative tool change, which takes place behind the table for fast, safe, collision-free cutter exchange, so the entire clamping surface is available for use. Compared to the predecessor model, the working volume is over 50% larger, creating new possibilities for machining complex components. The ability to employ 400 mm long tools is said to be a unique selling point in this machine class.
DMG Mori claims that a strong argument for investing in its travelling column machines has always been their stability, so the manufacturer has specifically considered this area. The DMF 200|8 has been designed in such a way that the cantilevered Y-axis has consistent rigidity over the entire traverse. Three linear guideways in the X-axis reinforce the stability of the machine and create the necessary basis for highly precise and productive machining. Even with the Y-axis slideway fully extended, maximum spindle power can be applied for machining.
