The DMU 200 Gantry from DMG MORI impressively combines the machining of large components and maximum dynamics. Users benefit in the aerospace and automotive industry as well as in model making and the energy sector. With the 5-axis machining of up to 30,000 rpm and optional ULTRASONIC or LASERTEC technology integration, more complex components weighing up to 10,000 kg made of aluminium or composites as well as welded components can be machined economically. The machine can be easily loaded from the top with a crane. The low gantry design of the DMU 200 Gantry enables optimum utilisation of the work area. With a footprint of no more than 4,300 x 5,400 mm, the machine achieves travel paths of 2,000 x 2,000 x 1,200 mm, with which DMG MORI is successfully complementing its product range between the DMF and the DMU P series. “The ratio of the large work area of 2 x 2 m to less than 24 m² footprint has also inspired our customers – even surprised them”, says Markus Rehm, Managing Director of DECKEL MAHO Seebach GmbH. They could already see this for themselves in July this year at DECKEL MAHO in Seebach, Rehm continues, and emphasises: “The DMU 200 Gantry is the ideal complement of the product portfolio for the machining of large components at the Seebach location.”
The combination of cast iron machine bed and gantry portal creates a solid basis for the high dynamics. With rapid traverses of up to 50 m/min and 0.5 g acceleration, large components can be machined efficiently. Depending on the field of application, two milling heads are available for 5-axis simultaneous machining, a 45° as well as a 90° milling head. The first one enables the best possible utilisation of the work area, while the 90° milling head enables the use of application-specific spindles, including the compactMASTER with a rotational speed of 20,000 rpm as standard in the 5-axis version. Additional spindle options comprise rotational speeds of 24,000 rpm, 28,000 rpm and 30,000 rpm. The vertical 3-axis version of the DMU 200 Gantry is equipped ex works with a speedMASTER spindle with 20,000 rpm. Adding to this is the optional ULTRASONIC milling head as well as the LASERTEC Shape Technology. This technology can be used to completely machine moulded parts including surface structuring.
The DMU 200 Gantry has extensive cooling measure for maximum part precision and surface quality.
For the machining of composites or modeling material like Ureol, a highly efficient tripartite dust extraction is optionally available. This consists of an extraction system on spindle nose, extraction system in the table area and a work area extraction system with continuous volumetric flow. The basic construction of the machine was already designed with this in mind. A package can be offered as standardised option as required.
The DMG MORI toolSTAR tool magazine has 30 pockets as standard. Optionally, up to 120 tool stations are possible. Good accessibility of the tool magazine from the front with separate operating panel is part of the ergonomical machine design. The DMU 200 Gantry is perfectly accessible from two sides. The DMG MORI ERGOline Terminal with 21.5" multi-touch screen and CELOS can be easily swivelled to both sides. In future, DMG MORI will optionally offer CELOS with HEIDENHAIN for the DMU 200 Gantry. Selected DMG MORI technology cycles are available in parallel. Examples are 3D quickSET for highest kinematic precision and ATC for top surface quality.
If required, the machine is supplied with a through-loading option. In this case, the control cabinet is positioned next to the machine, which enables improved accessibility of the work area from the front and the rear. Related to this is the possibility of automation. A high process reliability is provided by the excellent chip management. The chips get to the funnel-shaped machine bed on both sides of the table, from where they drop into the chip conveyors, which are included as standard, unhindered and are disposed of towards the rear.
With regard to the target markets, Markus Rehm has a clear vision: “The modular concept with through-loading option and two milling heads for 5-axis simultaneous machining as well as the high dynamics of up to 0.5 g predestine the machine for model making as well as the machining of structural parts or aluminium plate machining in the Aerospace industry. With regard to price, our machine just costs half of a comparable portal machine.”
