  • the eccentric is driven in rotation by a mechanism acting on its axis guided through the bolt, preferably by means of pneumatic actuation devices.
  • the locking eccentrics can give rise to difficulties when mounting and in particular when lifting the workpieces from the centering mandrels, namely because the rotary eccentric, due to its drive pneumatics, does not reliably project into the centering bolt swung back position is switched. Then there may be deformations of the sheet metal material in the area of the receiving opening of the workpiece, especially since the rotating eccentrics in the locking position do not lock evenly all around on the material surrounding the receiving hole, but only on a small circumferential area.
