This invention relates to machining of long profiles, that can be bent, held in place using two clamping arms ( 10 ) clamping the section to be machined. According to the invention, the profile ( 12 ) does not move during machining and the mobile arms are not used to move the profile in front of the tool; the arms move with the tool to the various locations to be machined. Auxiliary supports ( 25 ) are flexible in the plane of the profile and provide sufficient support while enabling the profile to deform as a result of stresses applied to it. Machining is more precise and remaining stresses are reduced.
