Abstract

Die Erfindung betrifft ein zweidimensional wirksames Messer (1) für Zerspanmaschinen, insbesondere für Holzspanmaschinen. Das Messer (1) weist eine Hauptschneide (2) und mindestens eine Trennschneide (4) auf, wobei das Messer (1) und die Schneiden (2, 4) einstückig ausgeführt sind. Darüber hinaus betrifft die Erfindung eine Vorrichtung zum Herstellen und Nachschärfen von zweidimensional wirksamen Messern (1) für Zerspanmaschinen, insbesondere für Holzspanmaschinen, mit mindestens einem Schleifwerkzeug (5, 8) sowie ein entsprechendes Verfahren. Das Schleifwerkzeug (5, 8), welches dazu dient, über das Messer (1) geführt zu werden, weist mindestens zwei winkelig zueinander angeordnete Schleifflächen (9, 10) auf. Auf diese Weise wird das Herstellen und Nachschärfen von zweidimensional wirksamen Messern und damit auch die Herstellung von Spänen optimiert.

The invention relates to a two-dimensionally effective knife (1) for metal-cutting machines, in particular for wood-cutting machines. The knife (1) has a main cutting edge (2) and at least one cutting edge (4), the knife (1) and the cutting edges (2, 4) being made in one piece. The invention also relates to a device for producing and resharpening two-dimensionally effective knives (1) for metal-cutting machines, in particular for wood-cutting machines, with at least one grinding tool (5, 8) and a corresponding method. The grinding tool (5, 8), which is used to be guided over the knife (1), has at least two grinding surfaces (9, 10) arranged at an angle to one another. In this way, the production and resharpening of two-dimensionally effective knives and thus the production of chips is optimized.
