The focus of the DMG MORI Open House event at Deckel Maho Pfronten, Germany, which took place in January 2016, was on the latest innovations and groundbreaking technologies.

On an exhibition area of 7400m², the machine tool manufacturer showcased in total 90 high-tech exhibits live in operation, including the DMG MORI best-sellers, six world premières featuring turn-mill complete machining, universal milling, XXL parts machining and other new technologies.

With 30 percent enhanced precision, performance and efficiency DMG MORI has set new standards with the fourth duoBLOCK® generation. Thanks to its proven duoBLOCK® design the 5-axis machine enables top machining performance and maximum precision with impressive dynamics. From hard-to-machine materials such as titanium, to the highest surface quality requirement, the 4th generation DMU 160 P duoBLOCK® offers the ideal conditions for industry, ranging from aerospace to tool and mould making.

The extensive cooling measures together with the top rigidity of the fourth generation of the duoBLOCK® concept are the basis for the very highest demands on precision and machining performance. Cooled guideways and drives plus the optional spindle growth sensor ensure minimum thermal-related displacement of just 12 µm.

Numerous features of the basic structure also promote the high long-term accuracy of the
DMU 160 P 4th generation duoBLOCK®. These include large linear guideways in all axes and standard double wipers, as well as the re-designed ball screw principle in the X- and Y-axes. In addition, the geometry of the Y-axis has been improved by means of an optimised fixator position. Fixation of the standard Magnescale measuring system in the Y-axis on a carbon plate has optimised the measuring accuracy, thus resulting in a more exact positioning accuracy of the table.

As the largest model in the series the DMU 160 P duoBLOCK® 4th generation has also been given a larger work area. This now measures 1600 x 1600 x 1100mm. Table dimensions are Ø 1600 x 1250mm and the maximum workpiece weight has been increased to 4500 kg. Productive and dynamic 5-axis machining is effected with rapid traverses of up to 60 m/min in all axes. The acceleration rates in the X, Y and Z-direction are 6 m/s², 4 m/s² and 7 m/s² respectively.

The modular concept of the DMU 160 P duoBLOCK® 4th generation offers an ideal solution for every application – starting with the innovative wheel magazine, which in its largest expansion stage can accommodate 453 tools (SK40/HSK63) and on to include the most extensive range of spindles to be found anywhere on the market. The offer here ranges from the powerMASTER® motor spindle with up to 1,000 Nm to the gear spindles with max. 1,800 Nm, and on to include the speedMASTER® spindles with their impressive speeds of up to 30,000 rpm. The standard version of the DMU 160 P duoBLOCK® 4th generation comes equipped with a motor spindle that achieves a speed on 15,000 rpm and a torque of 200 Nm.
