Crippa Linear Series 955LE

CNC tube bending machine with full automatic cycle. The 955LE is a CNC tube bending machine in the Linear series for tubes up to 55 millimetres in diameter. The frame of this tube bending machine has a standard length of 4480mm but the stroke can be extended with or without recovery cycle. The head of this model has direct transmission, a feature that increases its rigidity and effectiveness. The 955LE is a particularly advanced model because it has pneumatic balancing that improves energy saving and increases its performance. Like the other tube bending machines in the Linear series, the 955LE occupies little space and mounts a compact bending head, which can produce tube geometries that normally require a double bending direction in a single cycle. It is a multistack multiradius machine with manually reconfigurable bending direction, and can be fitted with a number of tools simultaneously with different radii and clamping. Its design was conceived for easy integration with the already existing tools. This tube bending machine also has a horizontal plane positioner to reduce damage to the machine to a minimum in the event of components accidentally colliding. Furthermore, all the movements of the machine’s axes are on recirculation guides which do not require lubrication and cause less wear compared to traditional guides. The machine also offers a high production rate and can produce bends with a CLR/DIA ratio even less than 0.8. The 955LE has 9 controlled axes that govern the movements of the machine and are driven by absolute digital electric motors with Full Electric technology and controlled by a CNC Siemens 840D sl. The operator can interact intuitively with the machine using the UII (User Iso Interface) three-dimensional graphical software on a 19” LCD touch screen. This machine is designed to be integrated into Smart Factory systems.
