The working area of a DMP 35 fitted with the options of a 25-position tool magazine and an integrated swivelling rotary table for five-axis machining

Capable of producing complex workpieces weighing up to 400kg efficiently, reliably and precisely from a wide range of materials, from aluminium to titanium, the new DMP 35 has been added to the range of vertical machining centres available from Coventry-based DMG Mori.

Occupying a footprint of just 3.15m² on the shopfloor, the standard three-axis version may be optionally supplied as a five-axis model and automated pallet handling can be fitted.

Axis travels of 350 x 420 x 380mm are generous considering that the machine width is only 1,285mm if a 15-station tool magazine is fitted, rising slightly to 1,410mm if an alternative 25-pocket magazine is chosen. Underlining the breadth of options available, a user is able to select a 24,000rev/min 52Nm inline spindle and an HSK-A40 or SK 30 interface in place of the standard 15,000 rev/min 78Nm spindle.

The machining centre is also fast. Up to 2g acceleration delivers a quick chip-to-chip time of 1.5sec. Rapid traverse of 60m/min in all orthogonal axes minimises non-cutting times. Linear scales are fitted as standard for feeding back axis positions to the Siemens control.

A further option is the integration of a swivelling rotary table for five-axis simultaneous metal-cutting. The stable design ensures vibration-free, accurate milling in applications demanding high quality requirements. A 40-bar internal coolant supply is offered as well as a chip conveyor with a capacity of up to 1,000cm³/min, ensuring high process reliability during production.

Requiring an additional floor area of 1.15m², a WH 3 automation unit manufactured by DMG Mori can be connected to the DMP 35. It is said to be particularly easy to program, even by inexperienced operators.

Rapid autonomous exchange of machine pallets fixtured with raw material or finished components raises productivity considerably. It additionally introduces the possibility of six-sided machining and allows long periods of unattended operation, including ‘lights out’.

DMG Mori also offers the DMP 70 with axis travels of 700 x 420 x 380mm for the production of larger components in a footprint of 4.2m².
