In aircraft construction, exceptional component quality and precision are crucial, for obvious reasons. However, sheet-metal aircraft parts are often extremely large, making machining and handling problematic. Working closely with CNC specialist Penta-Tec and with milling specialist A&T – a company that supplies Premium Aerotec, an Airbus subsidiary, with structural components – Harmuth CNC-Frästechnik has built large-format milling machines that use PC-based control technology from Beckhoff to successfully overcome these challenges.
