Abstract
Description
Es sind Sägeblätter bekannt, welche Zähne mit unterschiedlicher Breite und Stellung besitzen. Ferner sind Sägeblätter bekannt, bei denen der einzelne Sägezahn mehrere Hauptschneiden mit verschiedener Schneidengeometrie aufweist.It are saw blades known which teeth with have different width and position. Furthermore, saw blades are known where the single sawtooth has several main cutting edges with different cutting geometry.
Beim Zuschnitt von kunststoff- und furnierbeschichteten Holzwerkstoffen werden Sägeblätter eingesetzt, welche saubere Schnittfugen erzeugen. Ausreißfreie Schnittkanten auf der Werkstückunterseite erzielt man meist nur mittels Vorritzer, welcher entgegen dem Lauf des Sägeblattes wirkt.At the Cutting of plastic and veneer-coated wood materials Saw blades are used, which produce clean kerfs. Tear - free cut edges on the Workpiece underside one scores mostly only by scoring, which contrary to the run of the saw blade acts.
Der
im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde,
dass beim Einsatz eines Vorritzers und dem Aufbringen von Kantenmaterial
eine unerwünschte
Klebstofffuge entsteht (
Diese Probleme werden durch die im Patentanspruch aufgeführten Merkmale verringert.These Problems are caused by the features listed in the claim reduced.
Das Sägeblatt ist so gestaltet, dass sich durch die Anordnung der Hauptschneiden verschiedene Schneidenflugkreise ergeben. Die äußeren Schneiden s1 besitzen einen größeren Flugkreis als die inneren s2, Folge dessen bearbeiten diese das Werkstück zuerst. Die inneren Schneiden s2 besitzen dagegen eine größere Zahnbreite. Die Schnittkanten werden so nachgearbeitet.The sawblade is designed so that by the arrangement of the main cutting edges result in different cutting flight circles. The outer cutting s1 have a larger circle of flight as the inner s2, consequence of this work the workpiece first. The inner cutting s2, however, have a larger tooth width. The cut edges are reworked in this way.
Auf der Kreissäge- oder Formatkreissägemaschine kann das Sägeblatt so höhenverstellt werden, dass der innere Schneidenflugkreis nicht über die Werkstückoberfläche hervortritt. Die Schnitttiefe a ist somit größer als bei einem Vorritzer, dessen Schnitttiefe bei normaler Anwendung zwischen 0,8–1,5 mm liegt.On the circular saw or sizing machine can the saw blade so height-adjusted be that the inner cutting circle is not over the Workpiece surface emerges. The depth of cut a is thus greater than in a scorer, the depth of cut in normal use between 0.8-1.5 mm is located.
Stellt
man bei einem Werkstück,
z. B. einer beschichteten Flachpressplatte, eine Schnittkante mittels
Vorritzer her und bringt anschließend eine Kante auf, so entsteht
auf der Unterseite eine kleine aber sichtbare Klebstofffuge (
