Milling frames

Specialised cutting materials for machining titanium

Frames and stringers give the fuselage the necessary rigidity. Titanium is often used for the frames as it is extremely light. Its high tensile strength also helps reduce the number of components required. However, these positive characteristics come at the cost of demanding machining properties, which in turn require a corresponding level of expertise and high-performance tooling solutions.

CERATIZIT can get you off to a flying start with its specialised cutting materials, which ensure reliable tool lives and stable processes when roughing and finishing.
