ROUNDO 3-Roll Plate Bending Rolls

The ROUNDO 3-roll plate bending rolls provide the outstanding performance, reliability, and quality needed for high precision and high output rates. ROUNDO 3-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.

ROUNDO 3-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 capabilities.

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.
