High-precision five-axis machining of components up to 2,300mm long can be carried out productively on the new DMF 200|8 travelling-column machining centre from DMG Mori.

Markus Rehm, managing director of Deckel Maho in Germany, where the machines are built, said: "This is the latest in a line of such DMG Mori machines of which more than 2,700 have been installed world-wide. It takes the technology to a level of precision and performance never seen before."

Having a rigid table measuring 2,300 x 850mm and travels of 2,000 x 800 x 850mm, the DMF 200|8 offers users in the aerospace and mouldmaking industries, for example, scope to machine long components up to the maximum table load of 2,000kg.

Rapid traverse in the linear axes is 50m/min as standard, but with an optional linear drive in the X-axis it reaches 80m/min. Holistic cooling throughout the machine delivers long-term accuracy and tight tolerances.

The B-axis milling head with 6,000Nm maximum clamping torque offers a swivel range of ±120 degrees for flexible five-axis machining. A 15,000rpm speedMASTER spindle is standard, while an extensive choice of other modular spindles is offered including a 200Nm high-torque version and a 20,000rpm 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. So 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 by the 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 400mm 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.
