The second generation supports ultrasonic-assisted milling with a defined cutting edge. ![]() Ultrasonic technology from Sauer GmbH, a member of the DMG MORI group, is a major key to more gentle and efficient machining of composites and other materials such as ceramics or nickel-based alloys. TGR-E and DMG MORI have been cooperating for a number of years now to create the foundation for such machining, and the results can be seen in the machine shop. Such operations call for appropriate process know-how, suitable machining strategies and tools and, not least of all, a high-performance computerized numerical control system that supports the operator in every situation. Machining composite parts with inserts made of titanium and other difficult-to-machine materials is even more complicated. The individual layers must be prevented from separating from each other (delamination) and the fibers prevented from tearing. One challenge is presented by difficult-to-machine composites consisting of several combined layers made, for example, of carbon or Kevlar fibers. ![]()
