    摘要： 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.

    摘要： In a semi-hot forming operation, a workpiece is supported between two tool rollers which are rotated in the same direction. During the rotational cycle of the rollers the workpiece is first electrically preheated to a desired temperature after which the forming operation takes place. The contact pressure between the rollers and the workpiece is relatively low during the preheating operation and is increased when the roll forming takes place. To heat the workpieces effectively, the rotational speed of the roller can be varied to preheat at a regulatable reduced speed and then to form the workpiece at an increased rate of speed. The circumferential surfaces of the rollers are segmented with a smooth portion and a profile portion, with the preheating taking place when the smooth part of the rollers are in contact with the workpiece and the forming taking place when the profile portion is in contact with the workpiece.
