Abstract

A bevel is ground on the pre-cutter hollow teeth on a circular saw. This increases the durability of the tool, and then the remaining tooth points are ground inclinedly to the cutting edge. The teeth may be integral with the blade of the saw or may be mfd. separately and fastened to the blade. USE/ADVANTAGE - To improve the cutting effect of circular saws used in carpentry and joinery, and prolong their working life.

Description

Verfahren, Sonderschliff an Sägeblättern für Tischlerei- und Holzverarbeitungs-Kreissägen, Dachzahn-Hohlzahn-Kreissägeblätter.Process, special grinding on saw blades for carpentry and woodworking circular saws, Roof tooth hollow tooth circular saw blades.

Um möglichst ausrißfreie Zuschnitte an Kreis- und Plattenaufteilsägen zu erreichen, werden an herkömmlichen Sägen die "Vorschneider"-Hohlzähne spitz geschliffen.In order to cut out circular and panel saws as easily as possible to be achieved on conventional saws the "pre-cutter" hollow teeth sharpened.

Hierbei ist die Spitze des Hohlzahnes der Schwachpunkt bei der Standzeit des Werkzeuges.The point of the hollow tooth is the weak point here the service life of the tool.

Beim Zuschnitt entsteht auch an der Kante des zu schneidenden Material nur ein spitzer Winkel, durch welchen die Späne des zu zerspanenden Materials geführt werden.When cutting also occurs on the edge of the one to be cut Material only an acute angle through which the chips of the to be machined material.

Durch die Erfindung, Anschliff einer Fase an den Hohlzahn, wird die Standzeit des Werkzeuges erhöht, da die sehr anfällige Spitze entfällt.By the invention, grinding a chamfer on the hollow tooth, the service life of the tool is increased because the very vulnerable tip is eliminated.

Des weiteren wird die Schnittgüte des Werkstoffes verbessert, da eine Entastung der Schnittkante durch den Schrägschnitt gegeben wird. Das zu zerspanende Schnittmaterial wird zur Schnittmitte früher abgeführt.Furthermore, the cutting quality of the material is improved, there is a delimbing of the cut edge by the bevel cut is given. The material to be cut becomes Cutting center removed earlier.

Die Sägen eignen sich zum Zuschnitt von Kunststoff- und Melaminharz beschichteten Platten auf allen üblichen Kreis- und Plattenaufteilsägen.The saws are suitable for cutting plastic and Melamine resin coated panels on all usual circular and panel saws.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung Blatt 1, Bild 3.2 dargestellt.An embodiment of the invention is shown in the drawing sheet 1, Figure 3.2.
