4-roller plate bending machine has double-end pre-bending function.
The bending process is much safer and more reliable than other types of rolling equipment.
For the clamping force to plate between upper roll and bottom roll, the corresponding force can be adjusted by regulating valve in hydraulic station, according to different thickness and width of plates.
The upper and the bottom rolls of this rolling equipment work as the main drive.
There are side rolls on both sides of upper and bottom rolls. The side roll makes arc lift along with axes of bottom roll. When side roll moves upward, the bending plate will be bent and formed.
The bottom roll of this 4-roller plate bending machine lifts vertically. It can realize asymmetric bending.


CSM 4-roll  plate bending machine is often used for pipelines onshore and offshore, storage tanks, steel structures for platforms and wind turbines.
Our 4-roll  plate bending machines can be applied to shipyards (from bending ship hulls to production of submarine hulls), marine and storage tank construction (stationary storage tanks, reactor tanks, mobile tanks for road and rail).
Four Roller Plate Bending Machine is applicable for automotive industry (motors for wipers and starters, bushing for engine housing and axles, parts for catalytic converters, HGV (High Goods Vehicle) fuel tanks, transport tanks for liquids and fluids).
This rolling equipment is suitable for boiler and heat exchanger production, bending work on reactor assemblies and steel structures (section bending, pipe construction, cone and dome).


1. CNC plate bending machine is a hydraulic-driven machine with high efficiency (driving power is about 60% of the traditional one.)
2. CNC four roller plate rolling machine adopts permanent lubrication technology. During the bearing life period, it doesn't need refueling.
3. Clamping pressure is adjustable. There is non-existent skidding. The productivity is 50% to 80% more than three roller plate rolling machine.
4. The rolling diameter of this CNC four roller plate rolling machine (CNC plate bending machine) can realize 1.1 times of the top roll.
