Crippa Small Series 2ER

Tube bending machine with full automatic cycle. Reversed version of the SMALL2E, the SMALL2ER is a Full Electric multistack and multiradius tube bending machine with seven CNC axes created for aluminium tubes up to 20mm in diameter with a thickness of 1.8mm and with right and left bending directions integrated into the cycle. Its upside-down layout simplifies unloading phases for the processed tube, and its reduced size allows it to be easily inserted into production lines with little available space and into new and existing integrated work cells. Like the linear version, SMALL2ER is configured with an electrical arm and the main transmission of the C axis directly under the bending plane.

The head translates with typical cross movements. The reconfiguration from right to left happens through the pressure die axis in concert with a pneumatic displacement system on two fixed positions on the clamp carriage and the slide unit. The slide position blocking system prevents collisions during machine process phases. All main movements of the machine take place on recirculating ball bearing guides and all components have a high standard of quality to guarantee excellent overall performance and maximum availability of parts. Quality, energy savings and minimal scrap during production phases combine with extremely reduced set- up/start up times. Like other Small series tube bending machines, SMALL2ER also features high production rates and the possibility to be implemented with a broad array of accessories. The efficiency of the machine is guaranteed by the dynamics of the plane positioner which limits damage in case of accidental collision of the components. The machine can produce bends with CLR/DIA ratio even lower than 0.8; therefore it is suitable for production sectors that require high standards of repeatability and quality. The three-dimensional graphics software on a 19” LCD touch screen, the UII “User ISO Interface”, allows the operator to interact intuitively with the machine to program production and simulate and optimise bending programs. The SMALL2ER is designed to be integrated into Smart Factory systems.
