– Following pressure die with linear bearing
– Forward movement via pressure control valve
– Returned by hydraulic cylinder
– Include wide opening pressure die, to allow the off set bend device with the long neck clamping to move directly behind the bending tool
– The emergency area in front of the machine is controlled via scanner
– the machine is conform to the electric and mechanical security guidelines and  the CE norm
– You can change the safety area in the software according to your needs
– Attention: For each tube-Ø you need a separate collet
– For a correct positioning of the mandrel the machine is equipped with a mandrel support
– Includes mandrel lubrication unit
– Standard norm electric and hydraulic equipment
– Incl. stairs and balustrade at the beginning and the end of the machine for an easy walk through the machine ground frame during tool changing

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 text
– 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
