Blue Valley Head Offsetting Machines


The method is a bending or breaking action, much like a press brake, except the work piece is rotating. The upper roll on all our machines supplies this rotational drive and, at the same time, is the focal point where the flange is formed. Thus, the inside radius (knuckle radius) is determined by the radius machined on to the interchangeable upper roll.
