The handling of the machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a chuck or a gripper, which assures that it does not move while the jaws move in stages axially towards the work piece. After each pressing process, the jaws are turned by 360° (number of dies x2). This way they receive a completely round form according to the given die diameter.

The corresponding working parameters can be stored and managed in the machine control system. The user interface allows easy and logical operation. All essential processes are electronically monitored and the data is stored in the control system. This ensures high process safety and reproducibility.


Basic machine

  • basic module for the reception of all functional components consists of:
  • base panel with vertical assembly block
  • drive system: 2 servomotors with toothed belt discs/toothed belt (2 CNC axes)
  • recirculating ball screw with screw nut and double thrust bearings, adaption to shaft guide of cone ring for infeed of tools
