What Is 3-Roller Bending Machine – Definition, Application, Features ＆ More

A 3-roller bending machine is a type of plate rolling equipment utilized for shaping metal sheets, plates, and profiles into cylindrical or conical forms. These machines are distinguished by their utilization of three rollers in the bending process.

Typically, a 3-roller bending machine consists of two bottom rollers and one adjustable top roller. This configuration allows for precise control over the bending angle. The top roller’s adjustability facilitates achieving the desired curvature in the bent metal.

The primary advantage of employing a 3-roller bending machine lies in its superior control over the bending process when compared to machines with fewer rollers. By working in unison, the three rollers apply gradual pressure to the metal, ensuring precise and accurate bending.

Available in various sizes and capacities, 3-roller bending machines can accommodate a wide range of materials and applications. They find extensive use in the metalworking industry for manufacturing cylindrical tanks, pipes, tubing, and other curved metal components.

Krrass W11F series 3 roll plate bending machine adopts a strong electric welding structure, equipped with a super large steel roller. The side roller moves on a linear guide, bending the material near the tight point, thus ensuring that the device’s performance is comparable to that of the more expensive four-roller plate bending machine.

In addition, the bending roll motion of the series three-roller plate bending machine ensures optimal traction. For asymmetric geometry and thin sheet, it can effectively prevent it from sliding during the pre-bending process.
