Alternative energy sources are currently a hot topic and will most likely result in new solutions for potential energy savings and alternative ways to manufacture energy parts that are being developed. However, sometimes it does not require the wheel to be reinvented but simply for it to be implemented correctly.
Subsequently, Iruba Innovations GbR and Maschinenfabrik Berthold Hermle AG have joined forces, combining their current product highlights in a single manufacturing process specially designed for the power station, aviation, and machine construction industries.
New possibilities The C 60 U MT dynamic offers a range of complex processing options thanks to the unique machine design that comprises a NC swiveling rotary table and a torque drive with which workpieces of up to 1.5 t are accelerated to 450 1/min, while simultaneously being pivoted by +/-130° at 15 1/min. Combined with the patented trochoidal milling process from Iruba, this solution offers completely new possibilities and, above all, has the potential to provide large savings when manufacturing FanDisks. One of the benefits is that the rotary contour of the FanDisk can be turned from the whole in a single clamping setup, while the blade mounting grooves can be mounted directly using the new milling process.
Trochoidal Milling Process The trochoidal milling process is only completed with a defined partial wrap-around, as the milling cutter does not submerge into the full material but instead completes a program-controlled trochoidal curved movement therefore only ever touching one side of the workpiece. This process opens the groove and simultaneously provides it with the required "pine-tree geometry" using the special profiling cutter. This method, developed by Iruba GbR, particularly ensures that a very high level of process safety is achieved. Thanks to the contour parallel overmeasure, generated by the roughing cutters, as well as the adapted tool design, the pine-tree cutter that is especially designed for the finishing process achieves an excellent tool life and a very high surface quality during the synchronized and counter-run milling process.
Advantages of the "Pine-Tree Groove Cutter" from Iruba
- Traditional pre-milling process no longer required
- Increased process safety
- Cost-effective alternative for clearing operations
- Adaptable to various materials
- Variety of component sizes available
- Technology concept at the touch of a button
- Turn key projects
- An equally sized groove can be achieved with regrinded milling cutters
The C 60 U MT dynamic After the milling variant of the C 60 U dynamic was introduced in 2010, in 2011 Hermle adds the C 60 U MT dynamic to the machine series. Within the context of the internationally acclaimed high-precision and highly effective CNC 5-axes machining centers from the C-series, it goes without saying that based on the very high quality standards of Hermle and its end users in all industry sectors, the MT machine from Hermle AG does not simply represent "an upgraded by-product". This is why the technology and safety requirements that apply to lathes have all been taken into consideration during the development of the MT version of the C 60 U MT dynamic. This, for example, applies to the housing (EN 12417 applies to machine tools/machining centers, EN 12478 applies to machine tools/large lathes) as well as the dimensioning of the enclosures. The turning operations on the C 60 U MT dynamic can be completed with a pivoted table, and therefore do not only have to be completed in a horizontal position (90°), thereby offering completely new machining options, as well as increasing the flexibility of its applications. This is the reason why the upper enclosures including the roof of the machine were included in the safety concept.
