CNC-control system
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.
