Control description:  

– 3-axis control of the bending angle, the rotation axis and
the longitudinal movement in the different planes
– The control is working with three individual axis, bending, rotation and
longitudinal movement
– With 12″ Touchpanel for data input, memory capacity 1800 tubes with
20 positions each
– After input you can store the tube under the drg. number
– If the control registrates a breakwown or faults, you can see in the screen via
– Individual programming of every position possible
– Free programmability of the system without special CNC knowledge
– The bending program is automatically generated after input of the bending data
and can be manually optimized, if necessary
– Adjustments and optimization of the bending program during operation possible
In this way the set-up time is shortened especially for complicated geometries
and scrap for set-up is minimized
– Easy Cycle time optimization by easy programming of simultaneous processes
– The speed of the servo axes are synchronized automatically to minimize wear
and energy consumption
– Easy to use diagnostic tool, the software clearly indicates which action is being
carried out
– A bending operation can be divided into multiple segments if necessary
for example to allow different speeds for one bending process
– Easy integration of loading and unloading operations possible
– Incl. Ethernet and USB interface for data import and export
– The off set bend device moves to the front position for an easy input and
output of the tubes
