ABSTRACT:
A method for finish rolling workpieces of substantially circular cross-section to a selected diameter, in which the workpiece is engaged at circumferentially spaced portions by two rolls, at least one of which is driven for rotation about its axis, and in which at least one of the rolls is moved towards the other, until the portions of the rolls engaging the workpiece have reached a predetermined distance from each other in accordance with the selected diameter of the workpiece, and in which reaching of the predetermined distance is determined by measuring the distance of the peripheral surfaces of the rolls at selected points spaced from the portions thereof engaging the workpiece, and an apparatus for carrying out the method.
