Abstract

An apparatus (1) and a method serve for precision rolling of a surface area (2) of a rotationally symmetrical component (3), especially a screw. The apparatus (1) includes at least two spaced apart rolling tools (4, 5), a measuring unit (9) for determining an actual blank diameter of the component (3), an evaluating unit (10) for comparing the determined actual blank diameter of the component (3) with a predetermined blank diameter and for determining an adjustment value from the result of the comparison, and a control unit (11) for adjusting a distance between the at least two rolling tools (4, 5) in response to the adjustment value.
