  • Publication number: 20080170922
    Abstract: An apparatus is described for deburring with planing tools (7) a metal strand (1) cut to length by gas cutting, which planing tools are adjustably held each for themselves transversally to the metal strand (1) in a support (6), and with a drive for the relative advancing movement of the planing tools (7) relative to the metal strand (1) which is cut to length. In order to provide advantageous deburring conditions it is proposed that the annular support (6) comprises at least two sets of planing tools (7) which are radially adjustable to the metal strand (1) cut to length, which sets are arranged behind one another in the longitudinal direction of the metal strand (1) cut to length and which are staggered against each other set by set.
