Abstract (en)
A mechanical or optical measuring unit like mechanical tracer or camera determines the actual diameter of the component (3) held by a support (6) between two rolling heads (4,5). An evaluating unit compares the actual diameter with the desired finishing diameter to obtain an adjustment value. A control unit adjusts the distance between the rolling heads using the adjustment value. An independent claim is also included for method of precision rolling of a surface area of a rotationally symmetrical component.
