Abstract: The invention relates to a process for the production of parts from profiles. According to the invention, an alignment of the profile (6) is effected by means of two diametrically opposed, synchronously self-centering jaws (2 and 3) in one plane and the alignment in a plane perpendicular to this plane is effected independently of these jaws by two further, diametrically opposed, synchronously self-centering jaws (4 and 5). A processing center according to the invention is characterized in that the jaws (2 and 3; 4 and 5) form pairs of jaws, each pair of jaws being self-centering independently of the other pair of jaws.
