Chemically milling is a process for reducing the weight of a titanium or aluminium panel. This weight reduction cannot be done mechanically and requires technology using immersion in high-temperature caustic soda baths.

MECAPROTEC Industries performs chemical milling on aero-structure parts (for exteriors, leading edges) in order to reduce the weight, since this is a crucial issue in the aerospace field.
