Abstract: The invention relates to a device for clamping a blank part (10) to be machined, characterised in that it comprises a frame (20); means (21, 22, 23) for supporting the part to be machined; means (30, 31) for tightening said part (10) to be machined suitable for tightening said part (10) to be machined; controlled locking means (40, 41) with at least two states of said tightening means (30, 31), a locked state in which said tightening means (30, 31) are immobilised relative to the frame (20), and an unlocked state in which said tightening means (30, 31) are free to move relative to the frame (20), while keeping said part (10) to be machined tightened.

Abstract: 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.
