Calibrate the guide rails at regular intervals to maintain parallelism and alignment to the mill spindles. To do this: Use a straight edge and place against the entry and exit rollers of one of the guide rails. Extend the straight edge through the spindles of the first forming pass. Slide a machined roll onto one of the spindles – making ...

Roll forming is the process of bending metal into an engineered shape by passing it through a set of consecutive rolls and stands. Each stand gives the metal an incremental bend until the desired shape is achieved. Roll forming is an ideal technique to use when producing metal parts with long lengths in large quantities.
