1. Streamlined designed originated from EU, adopting whole welding and annealing treatment of the machine frame to eliminate stress.
2. Adopting Germany Bosch Rexroth integrated hydraulic system, hydraulic drive, stable and reliable, and can effectively reduce the problems caused by oil leakage.
3. Fixed top roller, bottom roller driven by hydraulic oil cylinder, left and right side rollers is driven by hydraulic pistons for diagonal movement.
4. CNC control, three group digital readout show the position of working roller, high accuracy and good roundness, material aligning is convenient and accurate, avoid the wrong side phenomenon.
5. Hydraulic Drop-end for easy removal of finished ferrule.
6. SAE 1050 Quality Certificated induction hardened forged steel rollers with high strength.
7. Hydraulic balancing system with self-tapping conical bending device is convenient for bending cone.
8. Permanent lubrication technology (bearings needn’t be oiled within service life), easy to add handling device, feeding device and material supporting device.
9. Consistently tightly clamp the top and bottom rollers during rolling process to prevent plate sliding.
10. Blade clearance quick adjusting mechanism, simple and quick manual adjustment method, supporting stepless adjustment of blade clearance

1. The four-roller bending machine is suitable for the bending and forming of metal plates. It can roll round, arc and tapered workpieces within a certain range. It has the function of pre-bending the end of the plate. The remaining straight edges are small, and the work efficiency is high. The metal sheet can be roughly leveled on this machine.
2. The four-roller and three-roller rolling machines have different roller motion forms, but the working principle is the same, they both use the principle of three-point fixed circle to carry out different radii rolling. However, the pre-bending straight edge and roundness of the four-roller bending machine are better than those of the three-roller.
