Combined forces at EMO

DMG Mori Seiki will be exhibiting 95 high-tech exhibits on its 10,237m² stand at EMO 2013.
The show held from September 16-21 at the exhibition centre will give the machine giant the chance to show 15 of its machines in the latest combined DMG Mori Seiki design along with 18 new premieres.

The new machines are some of the first to be produced under the combined brand of the German and Japanese companies since their merger plans were announced in 2009.

DMG Mori Seiki says the new uniform design demonstrates its consistently high quality standards. The machines offer customers improved functionality, user-friendliness and value retention. Some of the new features include: a maximum view into the work area for greater control of the machining process and being able to dismantle the safety glass from the outside, improved ergonomic display and keyboard controls for operators, personalised Smartkey start-up and improved scratch resistance. They are also available in black or white colour designs.

Added apps

The machines feature Celos software apps that can be installed on the machine such as ‘Job Manager' and ‘Job Assistance'. The apps enable integrated management, documentation and visualisation of jobs, processes and machine data. Celos is compatible with production scheduling and enterprise resource planning systems and can be linked to CAD/CAM software.

The machine's Ergoline controls are available in Siemens and Mitsubishi formats.
One of the other machines on the DMG Mori Seiki stand making its debut is the CTX Beta 2000 TC turning centre.

Gildermeister claim the machine has the biggest Y-stroke in its class. It offers entry level turning and milling capabilities on workpieces with turning lengths of up to 2,000mm.

For demanding, complete machining applications the lathe has main and counter spindles with a torque of up to 770Nm. Furthermore, the powerful turn-mill spindle with speeds of up to 18,000rpm allows the machining of complex workpieces and 5-axis simultaneous machining. The high flexibility is underscored by the tool magazine's capacity of up to 100 pockets and the option to use tools with lengths of up to 700mm.

With Z-axis travels of 2,050mm and a turning diameter of 550mm, the CTX beta 2000 TC is positioned between the smaller CTX beta 1250 TC and the large CTX gamma 2000 TC and complements the turn-mill turning centre series.

Pushing the envelope

Another machine from DMG Mori Seiki appearing for the first time at EMO is the CTV 315 Vertical turning centre for large workpieces of up to 300mm in length 210mm in height and weighing 25kg.

The large work envelope offers enough space for the VDI 40 turret with 12 tool stations and additional tools or a milling spindle, which can be mounted on an optional tool carrier. The turret is also available as a Direct Drive VDI 50 version with driven tools and rpms of up to 10,000. The design, which has been optimised for production environments, offers operators easy access to the work area and automation equipment due to its small footprint.

In combination with the (optional) Y-axis travel and big Z-axis stroke, workpieces with diameters of 20mm to 300mm can be precisely machined rapidly due to a linear drive in the X-axis. It reduces non-productive times through acceleration of 8m/s² and increases long-term accuracy. The machine's linear drives have a warranty of 60 months.

Sprinting performance

Another world premier will be the Sprint 65 turning centre. The latest edition to the Sprint series the turning centre is equipped with three turrets and the bottom turret is provided with a B-axis, unrivalled for automatic turning machines. The generous -23.5° to +158.5° swivel range of the B-axis makes working at negative angles possible, even with standard tools.

Alternatively, the Sprint 65 can be equipped with three turrets and no B-axis. The affordable, entry-level version with two turrets also comes with the patented Twin concept, with two turrets and a cross-traversable counter-spindle/tailstock combination allowing parallel machining in two independent work areas.

The standard Trifix precision quick change interface ensures setup times of less than 30 seconds and a repeatability of < 6µm. The intended field of application of the Sprint 65 is complete machining of bar material up to 90mm (65mm standard) in diameter with a speed of 5,000rpm on the main spindle and 7,000rpm at the counter spindle.

The Sprint 65 is delivered with Operate 4.5 on Siemens 840D Solutionline controls.
Operate 4.5 is DMG Mori Seiki's new platform for all machines with Siemens controls, from entry-level to high-end models. Operate 4.5 encompasses a machine tool's complete automation technology, from drives to control. Additionally, Operate 4.5 offers a uniform user interface for maximising machining productivity. New generation duo

Finally an advance in milling technology from DMG Mori Seiki comes in the form of the fourth generation Duoblock DMU 80 P. The 5-axis machine has cooling measures that are claimed to increase accuracy by 30% with long term positioning accuracy of 5µm.

The machine's rigidity has also been improved by 30%, providing maximum machining power. The new wheel-type magazine with space for up to 363 tools offers a rapid tool change time of 0.5 seconds as well as the possibility of set-up during machining for high flexibility and productivity. Moreover, the new B-axis with a 250° swivel angle and integrated cable carrier offers flexible and fast machining. Intelligent on-demand energy saving measures which reduce power consumption by up to 30% complete the new machine's impressive list of features.
