Tube Bending » 520


The 520 series of CNC tube benders offer multiple, fully automatic bending cycles. The clockwise and counterclockwise bending directions allow the creation of complex shapes without manual intervention during the bending cycle. This provides significant gains over other production means. The design of the machines allows for use of multiple and variable radius dies with straight and compound clamp dies. The bending head design integrates automatic loading and unloading of the part and the machines are prearranged for integration inside working cells. All five axes are driven by electric motors with digital Elect Motion technology and controlled by a Siemens 840 Dsl CNC. Linear axes utilize rack-and-pinion drives and linear bearings while rotational axes use gearboxes and gears or heavy-duty chains. The high production speed, the ability to integrate special devices, and the possibility of creating bends with a radius of less than 0.8D or push with variable radius bends mean that these machines are mainly used by those working in the automotive, aerospace, air conditioning, and furniture industries. The operator programs the machine through an intuitive interface on color LCD screen 19”. The three-dimensional graphics software, UII "User ISO Interface", facilitates the programming, simulation, and optimization of the bending cycle.
