Ring bending – three roller bending process

The stock is being transported between the rollers and forced into a circular path.CNC-bending, also called profile or 3-roller bending, is primarily used in bending large radiuses..

The stock that needs to be bend is transported between three rollers. The middle roller is forwarded and forces the stock into a circular path.

As a guidance the smallest bending radius is about 8-times the lateral cut of the profile (with pipes).

CNC-controlling makes reproducible batch production, ellipses, wave bending and also helical bending possible.
