A pressing tooling machine, including one or two punches, a die including sectors that can separate from each other but are connected to a shared primary portion, and a ring surrounding and holding the sectors, against which it is adjusted by tapered surfaces, and the altitude of which varies owing to the rotation of a crown provided with a surface in relief. When compression is finished, stripping is preceded by a slight separation of the sectors, which makes it possible to release stresses in the compressed piece and avoid many risks of damaging the piece. The sectors are made resistant by inserts made from a hard material, generally removable and able to be machined to an exact profile of the pieces to the formed.
