Max. centre line radius 250 mm
Max. centre line radius with a standard shaft 50 mm
Min. centre line radius with a standard shaft 50 mm

Specification of basic machine

Basic machine
  • pneumatics, hydraulics and mechanics built according to the VDMA, ISO and DIN norms

Standard equipment


  • control panel including CNC system with emergency stop
  • foot pedals
  • automatic retraction tools with rotating hub
  • emergency gates on both sides of the bending head
  • complete equipment for booster bending, including holder for booster die
  • max. pressure-lenght = 700mm
  • equipment for split tools
  • equipment for serpentine coil bending

Description of the pressure die booster, W-axis

  • programmable start push of the booster, i.e. 2mm, to prevent wall reduction at the start of the bend
  • programmable extra pressure/speed (mm/degree) of the booster, to minimize wall reduction and ovality of the bent tubes
  • programmable boosting angle, during which the extra pressure/speed is requied
  • programmable brake angle at the end of the programmed bending angle, to stop wrinkling at the inside of the bend
  • programmable stop of the booster, to stretch the material at the end of the bend
  • general or individual programming of each separate bending movement
