Cutting pocket corners with an only slightly inclined land is a routine task that requires the angular position to be changed in a machining centre. Here’s how Premium AEROTEC GmbH was able to address that. Article by Starrag.
Premium AEROTEC GmbH is a manufacturer of structures and manufacturing systems for aircraft construction. Headquartered in Augsburg, Germany, the company was formed in 2009 when the EADS plant in Augsburg was merged with the Airbus Deutschland plants in Nordenham and Varel.
Established in 1936 as an engine factory, the production facility in Varel handles engine overhauling, and spare parts production for truck and aircraft engines. It employs around 1,600 staff and produces nearly five million components a year, making it one of the world’s leading high-tech sites for aircraft construction.
For Premium AEROTEC, cutting pocket corners with an only slightly inclined land is a routine task that requires the angular position to be changed. While standard fork-type milling heads typically make huge swivel movements to do this, Starrag’s ECOSPEED machines’ tripod heads have significantly faster and more dynamic machining capabilities.
Starrag machining centres with parallel kinematics have proven themselves a worthy addition to one of Europe’s most advanced machine pools. This was reason enough for Premium AEROTEC to opt once more for highly dynamic five-axis simultaneous cutting with a tripod head for their plant in Varel. Due to these advantages, there are now 13 ECOSPEED machining centres in use in Varel.
“In addition to their reliability, it was the high overall dynamism of the ECOSPEED machines that won us over,” explains Christian Welter, Head of Large-Part Production at Premium AEROTEC. “This is why we chose two ECOSPEED F 2040 machines as our latest investment, which have been linked to create a flexible manufacturing system.” This is the newest highlight of Hall 8, where Starrag machining centres with a drive power of 120 kW currently take centre stage. An angled milling head that can be changed automatically now enables aluminium workpieces measuring up to 4 m long to be machined on the flexible manufacturing system (FMS)—not just completely, but in a single clamping position too.
