Control description:  

– Fitted with 3-axis control of the bending angle, the rotation axis and the longitudinal movement in the different planes
– The bending axis, the rotation axis and the length axis are coupled with each other, it ensues a permanent actual and nominal comparison also the control checks the tolerance and actuates further operations
– Integrated computer – IBM-compatible, current technology
– It ensues a permanent actual and nominal comparisation on the screen
– User surface Windows
– Separate control element including Tozchpanel for setup and start of automatic cycle


Standard equipment CNC control:    

– With max. 20 different positions of each tube, all positions are controlled in the PC program
– Possibility to store 1 Mio. tubes with 20 positions each under drg. numbers
– After input you can store the tube
– Storage of the drg. numbers according to WIN Standard
– The off set bend device moves to the front position for an easy input and output of the tubes
