Basic machine

  • basic module with fastening holes for the reception of all functional components consists of: base panel with carrier for motor with gearing and spindle ball bearing
    • drive system: 1 servomotor + gearing + encoder and motor cable 3/5m (1 CNC axis) ball roller spindle with screw nut for infeed of compression lever system to transmit power to force ring and toggle lever with tools
  • forming head with lateral slot for easy insertion of component part
  • jaws (forming tools) adjusted to client specific final outline
  • flat and circular compression possible; for round compression jaws have to be fitted to a diameter
  • possible number of jaws: 6, 8, 12 or 16
  • closing and opening stroke are steered over relevant curves by a servomotor
