Abstract: A machining tool has a body that includes a central tubular portion forming a duct centered on a longitudinal axis. A peripheral tubular portion is coaxial with the central tubular portion and surrounds the central tubular portion. A first machining stage has a first arm and a second arm that extend on either side of the central tubular portion. The first arm and the second arm each have a machining member at the end thereof. The first arm and the second arm are each integral with the central tubular portion and the peripheral tubular portion. The machining tool body also includes a baseplate. The peripheral tubular portion has at least one linking arch connecting the first arm and the second arm and bypassing the central tubular portion.

Abstract: The invention relates to a crimping blade with a profile such that the angle of attack ? of the sheet metal to be crimped remains constant during the entire crimping phase. In this way, the force applied to the sheet metal is always at the same angle in relation to the sheet metal.
