Abstract

Die Erfindung betrifft ein Verfahren zum Schleifen der Messer, die im Messerring eines Zerspaners eingespannt sind und deren Schneiden im wesentlichen parallel zur Messerringachse verlaufen;

  • wobei mehrere Schleifwerkzeuge in Richtung der Messerringachse intermittierend und gleichzeitig verfahrbar sind, um einzelne Messer zu schleifen;
  • wobei der Messerring während des Schleifens stillsteht und während der Schleifpausen entsprechend der Teilung der Messer über den Umfang des Messerringes um seine eigene Achse verdreht wird.
    • The invention relates to a method for grinding the knives which are clamped in the knife ring of a chipper and whose cutting edges run essentially parallel to the knife ring axis;
  • wherein several grinding tools are intermittent and simultaneously movable in the direction of the knife ring axis in order to grind individual knives;
  • the knife ring being stationary during grinding and being rotated around its own axis during the grinding pauses in accordance with the division of the knives over the circumference of the knife ring.

    • Die Erfindung ist gekennzeichnet durch die folgenden Merkmale:

  • jedes Schleifwerkzeug schleift jedes der Messer derart, daß der erwünschte Gesamt-Schleifabtrag mit dem im Umlaufsinne des Messeringes letzten Schleifwerkzeug erreicht wird.
    • Figure 00000001
    The invention is characterized by the following features:
  • each grinding tool grinds each of the knives in such a way that the desired total grinding removal is achieved with the last grinding tool in the sense of rotation of the knife ring.
