Crippa 963LE
Customised tube bending machines for every diameter
Tube bending machines from the Linear series have small bending heads that allow them to create particularly complex geometries in a single work cycle. These machines can form multistack and multiradius bends with manually reconfigurable bending direction, and can made bends with CLR/DIA ratio even less than 0.8. The nine controlled axes that govern the machine’s movement are driven by absolute digital electric motors with Full Electric technology and controlled by a CNC Siemens 840D sl.
Description
The 963LE is a CNC tube bending machine in the Linear series for tubes with a diameter of up to 63 mm with a completely automatic work cycle. The 963 LE’s frame has a standard length of 5600 mm but the stroke can be extended with or without a recovery cycle. The 963LE is an advanced model for its pneumatic balancing that saves energy and increases performance. The extremely small steel bending head equipped with chain driven transmission provides more space under the machine’s head allowing the machine to bend tubes with complex geometries in a single cycle. The bend can be reconfigured manually by the operator quickly and intuitively such that set-up and start-up is minimal. Like the other machines in the Linear series, the 963LE can also be fitted simultaneously with several tools with different radii and clamping, and even already existing tools. The 963LE can be equipped with a vast range of accessories, such as the Tangent Boost device which pushes the tube axially all the way into the wiper die region during bending, speeding up the process and reducing scraps. The high production rate, the ability to produce bends with a CLR/DIA ratio even lower than 0.8, and the ability to thrust bends with variable radius make this machine suitable for sectors where efficiency and productivity are the prime requirements. The machine’s 9 axes are driven by absolutely digital electric motors with Fully Electric technology and controlled by Siemens SINUMERIK 840D sl. The 963LE also has a three-dimensional graphical sofware on a 19” LCD touch screen for the operator to interact intuitively with the machine to simulate and to optimise the tube bending programs. This machine is designed to integrate into the Smart Factory system.
