Roundo PASS-205 Roll

The CNC system controls the machine and positioning of rolls with the highest possible precision. We guarantee a positioning within 0,1 mm (0.004”) of the side rolls and lower roll, even under varying load. These tight tolerances, unmatched by any competitive machine, are a direct result of the high mechanical precision and rigidity of the machine.

With clear commands and pre-set functions, the operator can create programs in a simple, yet logical way. Programs can also be created via the “Teach-in” function. Our unique geometry program enables users to create programs directly from drawings, and to quickly calculate the position of the side rolls to achieve a given radius. The interpolation function allows the machine to simultaneously rotate and change position of one of the side rolls, achieving varying radii and smooth transitions on the plate.

Roll parallelism is critical for achieving precise bends and optimal CNC control utilization. ROUNDO® machines maintain this parallelism reliably, even under maximum load. PASS machines adjust the lower roll using wedge blocks and a hydraulic cylinder for accurate alignment. PAS machines electronically regulate the parallelism of the lower and side rolls through a digital control system, ensuring precision with glass-scale linear encoders monitoring roll position.

All machines have fully hydraulic roll rotation, side roll and lower roll adjustment and drop end control. Combined with infinitely variable speed adjustment, the operator will have full control of the process in any bending situation. The high drive torque makes it possible to prebend with maximum capacity and to bend a plate with maximum plate thickness down to a small radius in only one pass. All ROUNDO® 4-roll plate bending machines have precise control of the speed difference between top roll and lower roll.
