The Deckel Maho DMF 260 Linear travelling column machining centre from DMG is designed for high levels of productivity and greater production flexibility.

It has the inherent stability of a mineral-composite bed and a high-speed rapid traverse rate of 80m/min to its swivelling spindle, which is derived from the use of linear drives to cover the 2600mm X-axis and 700mm in Y- and Z-axis.

The machine is also able to maintain positioning to 10 microns.

The flexible configuration of the DMF 260 Linear provides a wide range of options for its use.

For instance, the 2600mm by 700mm fixed table area can be used for components and the 700mm diameter NC rotary table provides five-sided access to a part.

The large table and integrated C-axis rotary unit can both be used to accommodate the same component, for example, datum face machining prior to being loaded to the rotary table.

Alternatively, simultaneous production of entirely different parts can be utilised.

It is also possible to mount a second NC rotary table alongside the first to provide a productive pendulum machining operation, each having a five-axis and five-face machining potential.

Servicing the table is a B-axis, swivelling milling head providing +/-100deg of rotary motion to the SK40 spindle, which is powered by a 23.5kW motor delivering 14,000rev/min as standard or 18,000rev/min as an option.

There is a choice of 30, 60 or 120 tool pockets in the ‘guide-along’ magazine design giving fast chip-to-chip times of under five seconds.

Each pocket in the magazine is able to support tools up to 300mm in length and 80mm diameter or 130mm diameter, with the adjacent position vacant.

Tool measurement via Blum-Laser/TT140 is also an option.

The machine features the latest DMG-branded guard design with two large, slide-aside doors giving a good operator view and access to the table area.

As part of the guarding system, overhead clearance accommodates the use of a crane for manipulating large and heavy components or fixtures.

Indeed, this is confirmed by the maximum table loading of 2.1 tonnes.

DMG’s Ergoline control with 19in screen is included with a choice of either Siemens 840D solution line including Shopmill Open or Heidenhain ITNC 530 with Smart.NC.
