A canter for processing a log by directly cutting into chips the material removed from the log, comprises a rotatable canter member which essentially has the shape of a truncated cone and on whose circumferential surface are provided replaceable processing means (4, 4') for cutting away material from the log. These processing means have a cutting edge structure which is composed of two substantially straight cutting edges (22, 22') at an angle to one another. According to the invention, the cutting edge structure (22, 22') is composed of at least two separate, flat processing means (4, 4') in the form of indexable inserts each having at least two separate, straight cutting edges (22, 22'). The processing means are so angled to one another that at first cutting edge (22) extends substantially radially perpendicular to the axis of rotation of the canter member, whereas a second cutting edge (22') extends at an angle to the first cutting edge, preferably in parallel with the circumferential surface of the cone. |
