CNC Bending

CNC Bending

Steel can be curved by roller or section bending. This process involves progressive bending of a section through a set of bending rolls that are shaped to the cross section of the bar. On each pass through the rolls, more bend is created and the process is repeated until the desired curvature is achieved. Pulling units are used on most beam sections curved on the x-x axis (the strong way). This is used to maintain the cross section of the web during bending.

Plate bending is similar to section bending but the bending rolls are horizontal and are longer. Plate is fed in flat and on each pass through the rolls, more curvature is introduced and the process is repeated until the desired curvature is achieved.

Tube bending is carried out in a similar way to section bending. Generally, a tube is stronger than its equivalent size beam so, to bend it, more force is required. During bending the outer profile of the tube is supported by sets of machined rolls.

Our three automated CNC bending machines enable us to precisely bend most materials and thicknesses up to 12m in length.
