Series C now with milled and machined Rotary combined

The best example of this is the extension of the machining centers of high-performance 5-axis CNC C 50 U dynamic with a MT version (where MT is Mill/Turn), characterized by a turntable fully integrated, with whose help is can carry out the demanding milling / turning a subject. This novelty also takes advantage of the new machining C 42 U Center dynamic that has just been presented, which is available from the start as C 42 U MT dynamic in the Mill/Turn version.

The MT machine of Hermle AG is not simply 'a refitted derivative' in the framework of the 5-axis CNC precision machining centers, and with this high-performance of the C series, is understood by the extremely demanding of Hermle AG manufacturer quality requirements Therefore MT versions of the C 42 U MT dynamic and C 50 U MT centers dynamic also have taken fully into account valid technological and security requirements for lathes. This concerns, for example, the fairing (for machine tools / machining centres applies the standard for machine tools, EN 12417 / big lathes, standard EN 12478) and the sizing of the coatings. As in the case of C 42 U MT dynamic and C 50 U Mt dynamic can be all Rotary machining even with the tilted table, that is, not only in the horizontal position of 90 °, which offers completely new possibilities of machiningas well as a greater flexibility of use, it has also included the upper cladding including the roof of the machine in the concept of security.

The known construction of modified gantry type primarily offers ideal requirements for the integration of the combined rotary axis (axis A) with the axis of the turntable (C axis). The axis to the bed of the machine hosting guarantees extremely high rigidity being the engine directly in the stretch of the toothed wheel driven. In the (A. axis), instead of a simple CN turntable and only for the positioning of the piece, is now a tilting circular table CN, which rotates in the C 42 U MT dynamic with a maximum of 800 revolutions per minute and in the C 50 U MT dynamic of larger size with a maximum of 500 revolutions per minute. Powered by engines of pair of high-performance for comparable high speed, can be demanding rotating machined and milled and machined Rotary combined in the form of roughing and finishing operations. The surface of subject in the turntable of the C 42 U MT dynamic is 750 mm in diameter and in charges of the table are allowed on a nominal basis 600 kilos. In the C 50 U MT dynamic, are 1000 millimeters in diameter and nominally 1,000 kilos of loading of the table. The best of the MT concept of Hermle AG is that the Rotary machining not only can be in a position of 0 ° and 90 ° tilting circular table CN, but also in any intermediate position. As a result, very short lathe tools can be used. The main spindle is blocked in rotating operations. HSK-T version presents the sizes 63 and 100. In this case it is important to the functionality of milling remain completely.

Maximum through a system of balanced security integrated

The main spindle is blocked, allowing transfer without problems even larger pairs and to position itself exactly the lathe tool in a reproducible way. The accredited concept of 5-axis-C-series also presented in the MT versions its practical advantages, as compared to the competing machines, machining C 42 U MT dynamic and C 50 U MT centres Hermle dynamic show an outline of maximum failure clearly superior in the area of displacement of the spindle, which means that also correspondingly larger pieces through the milling can machining / turning combined in one set-up. So that by the inertia mass produced during the turn / rotation there are no problems or damage, Hermle AG has introduced a balanced system integrated in the turntable as a novelty. By means of this also can balance accurately pieces of maximum including the subject of the tool system size and weight, which fully guarantees the safety of the operation even at maximum speed.

It also features a new system of supervision of broken tools and measuring tools; in this case, the tools of milling is measuring by laser and lathe, security tools, feel by a transducer 3D from both sides in a mecánica-electrónica manner. Combined machining of milling / turning translates into a complete process which is requesting and implementing more and more. In order to guarantee it also in terms of tool technology, Hermle AG has developed modular additional warehouses which are characterized by a building compact, a single link to all the Hermle machining centres, a high capacity of accommodation in comparison to the space required andFinally, as a concept of operation that facilitates the work extremely. Designed as warehouses of shelves are installed behind the machining centers: from there, the operator has a free access at ground level to a height of loading and unloading ergonomically optimal and can change the drilling toolsmilling and lathe even during machining. The new additional warehouse offers space for Max. 42 (41 + 1 = store jobs more job preparation) tools, which may have diameters up to 250 mm, lengths up to 430 mm and weights up to 30 kilos. Ready for Assembly and for the operation, the additional store can easily installed without any transformation and quickly put into service.
