ROUNDO PAS 4 ROLL

ROUNDO 4-Roll Plate Bending Rolls
The ROUNDO 4-roll plate bending rolls provide the outstanding performance, reliability, and quality needed for high precision and high output rates. ROUNDO 4-roll machines are built to the highest precision and rigidity possible! The frame of every ROUNDO plate roll is stress relieved after welding, then machined on precision CNC machining centers to insure the highest possible accuracy. Roll parallelism is one of the most crucial factors in achieving superior bending results. This is ensured on all ROUNDO plate rolls, even under maximum load.

ROUNDO 4-roll Plate Rolls have the highest drive torque, greatest bending roll force, largest rolls and roller bearings, and heaviest frame components of any competitive machine! ROUNDO machines are fully hydraulic with outstanding pre-bending capacities (with flat ends as short as one times the plate thickness).  Machines feature infinitely variable rolling speed and roll adjustment speeds as well as cone rolling including pre-bending of the cone plate.

All ROUNDO models can be equipped with CNC controls. The ROUNDO CNC system can control up to 12 axes, including the rotation and positioning of the rolls, plate in-feed systems, material handling equipment, and even auxiliary devices needed to fully automate the production process. The ROUNDO CNC control system can position the rolls to within ± 0.004”, even under varying loads. These tight tolerances are unmatched by any competitive machine. Programs can be created in a simple yet logical way. “Bending Wizards” allow a wide array of shapes to be programmed simply by selecting the shape and entering the desired radius.

ROUNDO 4-roll plate rolls are the preferred machine for the wind tower industry. Conical tower sections can be produced in a single pass using the unique capabilities of the ROUNDO CNC control system to position and tilt the rolls accurately and repeatably. While the initial investment may be higher, the greater efficiency, productivity and lower maintenance requirements quickly give the ROUNDO plate roll the lowest cost of ownership of any competitive machine.
