Abstract
A device for machining a plurality of rolls (4) which are mounted ready for use in a rolling stand (3) and form a common sizing pass (6) has at least one tool (5) which is disposed outside the sizing pass (6) for machining the working surfaces of the roll. In order that the shape and size of the sizing pass formed by the rolls is as accurate as possible, a measuring device (8) engages in the sizing pass (6), and a computer (10) compares its actual values with predetermined desired values, the resulting error signals being used to control the tool via servomotors (13, 14).
