The Secret Behind the Popularity of the Four-Roll CNC Plate Bending Machine

A CNC bending machine is a versatile piece of equipment that rolls metal sheets into cylindrical, arched, or other shaped workpieces. By utilizing the principle of three points forming a circle, it employs changes in the relative positions of the workpiece and rotational motion to produce continuous plastic deformation of the sheet metal, thereby achieving the desired shape. CNC bending machine tools are indispensable in industries such as stainless steel products, decoration, packaging, metallurgy, aviation, automotive, shipping, containers, and instruments.
The four-roll CNC rolling machine is primarily designed for wind turbine tower production, capable of manufacturing and processing various models of wind turbine towers. It has also found extensive application in industries such as shipbuilding, petrochemicals, aviation, hydropower, decoration, boiler, and electromechanical manufacturing, where it is used to roll metal sheet materials into cylindrical, conical, and arched plates, among other components.
Nantong Guoji Machinery's four-roll CNC plate bending machine significantly reduces the occurrence of remaining straight edges, lowers production costs, and improves efficiency through its optimized roller spacing arrangement.
During the rolling process, the four-roll CNC roller machine keeps the upper roller stationary while the lower roller moves vertically to clamp the steel plate. The side rollers move either straight or in an arc towards the upper roller to adjust the curvature radius of the coil. Although the roller movement patterns differ between the four-roll and three-roll CNC roller machines, their working principles are the same, both utilizing the three-point circle principle for varying radius rolling. However, the four-roll CNC roller machine offers better straight edge pre-bending and circularity correction compared to the three-roll machine; within the same time frame, the processing efficiency of the four-roll CNC roller machine is twice that of the three-roll machine.
