In future the DMG MORI series of high-precision DIXI machining centers from Le Locle will start off with the DIXI 125.

Unparalleled accuracies are the be-all and end-all when it comes to the topic of the DIXI series. Exceptional machining centers are created under unique conditions in Le Locle, Switzerland, centers that can produce even large components with diameters up to 3,000 mm, heights of 1,600 mm and weighing up to 12,000 kg with volumetric accuracies in the µm range. With the DIXI 125 DMG MORI now offers the ideal solution for smaller components.

The DIXI series achieves these impressive results through the symbiosis of excellent machine engineering, manual scraping of the guideways and perfect production conditions. Innovative cooling concepts include, among other things, completely water-cooled feed drives and guide contact surfaces to ensure absolute thermal stability. In addition, acceleration rates of up to 6 m/s² and rapid traverses of 60 m/min provide the DIXI machines with the dynamics necessary to manufacture sophisticated precision components productively.

DMG MORI has extended the high-precision machining centers in the DIXI series to include the smaller DIXI 125 for workpieces with diameters up to 1.250 mm. Like its bigger sister models, this world premiere also impresses with its unparalleled volumetric accuracy. The basis for this are the manually scraped guide contact surfaces with flatness and straightness values of 3 µm when mounted and a perfect machine structure that makes it possible to limit geometric tolerances by up to 80 percent. Positioning accuracy in the X-, Y- and Z-directions are 4 µm, 3 µm and 4 µm respectively and 4 arc seconds for the B- and C-axes. Volumetric accuracy is not measured until the machines are installed on site and is less than 15 µm. Users can get this impressive degree of accuracy for an additional price of around just 20 percent compared to standard machining centers in this class.

A 980-liter coolant unit with reference-guided temperature control of the feed drives, guides and machine structure plus a powerful machine cooling unit guarantee the extreme thermal stability of the DIXI 125. The thermo shield and individual thermal compensation including spindle growth sensor contribute additionally to this high level of thermal stability.

Based on the 4^th generation duoBLOCK^® the DIXI 125 as the smallest model in the DIXI series nevertheless offers a generous work area of 1,250 x 1,250 x 1,150 mm. The NC-controlled rotary table has a maximum load capacity of 2,000 kg.

Like all high-tech machines from DMG MORI, the DIXI 125 also comes equipped with CELOS^®. This uniform app-based user interface with its unique multi-touch screen is as simple to operate as a smartphone. As a result, users benefit from a 30 percent saving in setup time and 50 percent less effort for calculating technical values and searching for important information.
