Title
(EN) SAW BLADE TOOTH FORM AND METHOD THEREFOR
(FR) FORME DE DENT DE SCIE ET SON PROCEDE DE FABRICATION
Abstract
(EN)
A saw blade (100) has a plurality of teeth (104) with each tooth formed by a beveled gullet (110) forming a trailing face (118), a beveled gullet (110) forming a leading face (116) and a planar surface (122) forming a curved cutting edge (120). The gullets are beveled in opposite directions. The planar surface is generally parallel to the beveled trailing face. The tooth profile provides a saw tooth having a positive rake angle (128) to significantly improve the strength of the tooth. The method of manufacturing of the tooth profile begins by orienting a saw blade blank (160) about three axes and performing a first grinding operation which forms every other tooth gullet and every other planar surface. The partially formed blank is then oriented about two of the three axes in an opposite direction and a second grinding operation is performed. The second grinding operation grinds the remaining gullets and planar surfaces.
(FR)
Lame de scie (100) présentant une pluralité de dents (104), comportant chacune une gorge biseautée (110) constituant la face d'attaque (118) et une gorge biseautée (110) constituant la face de dépouille (116), et une surface plane (122) formant une arête de coupe curviligne. Les gorges de la face d'attaque et de la face de dépouille sont biseautées dans des directions opposées. La surface plane est généralement parallèle à la face de dépouille biseautée. Ce profil définit des dents présentant un angle de coupe positif (128) qui accroît sensiblement la force de la dent. Le procédé d'usinage de ce profil consiste tout d'abord à orienter l'ébauche (160) autour de trois axes puis à effectuer un premier meulage qui consiste à former une gorge sur deux et une surface plane sur deux. L'ébauche partiellement usinée est ensuite retournée autour de deux de ses trois axes en vue de la deuxième opération d'usinage qui consiste à meuler les gorges et surfaces planes restantes.
