Machine Details

Standard equipment

  • Programmable speed- and pressure setting of the booster unit
  • Individually programmable speed and acceleration/retardation of each axis
  • Laser scanner for clamp jaw and pressure die
  • Programmable tolerance range of each separate axis
  • Standard components from well-known european manufacturers


  • Online connection with CAD system or measuring machine
  • Customized software
  • Macro programming
  • Automatic tube magazine with automatic tube loading

CNC-control systems

The control system works with 4 individually programmable axes

  • Bending
  • Tube rotation
  • Length feeding
  • Booster pressure/speed

The CNC-system is a close loop system which does not allow the machine to continue before previous movement has reached its programmed position. To optimise the accuracy and speed of the machine the degree of tolerance is programmable. Normal programmed tolerance is ±0,05-0,1 mm/degree.
