Abstract: A method and device for controlling the feed rate of a saw blade which is provided with teeth and rotates about a center point relative to a workpiece during a machining process. During a rotation of the saw blade about the center point, the feed rate is selected differently during a machining process effected by teeth of different sectors of the saw blade, wherein the feed rate is selected to be lower during a machining process effected by teeth of sectors having larger radial spacing of the teeth from the center point than during a machining process effected by teeth of sectors having smaller radial spacing of the teeth from the center point. In this way, the operation of the saw blade can be optimized and the service life can be increased.

Abstract: An apparatus is described for deburring with planing tools a metal strand cut to length by gas cutting, which planing tools are adjustably held each for themselves transversally to the metal strand in a support, and with a drive for the relative advancing movement of the planing tools relative to the metal strand which is cut to length. The annular support includes at least two sets of planing tools which are radially adjustable to the metal strand cut to length, which sets are arranged behind one another in the longitudinal direction of the metal strand cut to length and which are staggered against each other set by set.
