Title
(EN) METHOD FOR THE MANUFACTURE OF A BAND SAW BLADE, SAW OBTAINED AND DEVICE FOR CARRYING OUT THE METHOD
(FR) PROCEDE DE FABRICATION D'UNE LAME DE SCIE A RUBAN, SCIE OBTENUE ET DISPOSITIF PERMETTANT LA MISE EN ×UVRE DU PROCEDE
Abstract
(EN)
Saw blade comprising sets of 4 to 6 teeth, the number depending on the blade length, at least every fourth, fifth or sixth tooth being less high than the other teeth, by 6 to 8 tenths of a millimeter. The method for the manufacture of a band saw blade with one or two cutting sides comprises the steps of forming a band with side clearances on the faces of the side corresponding to the cutting surface; forming on the cutting edge constant pitch toothed profiles of the same height: compressing the tip of each tooth to form the saw kerf, sharpening each tooth; surface grinding the profile of the rear and tip of at least one tooth in n teeth to lower its height in relation to the other teeth by a defined value. A sharpening machine for carrying out said method includes, on the cam mechanism for forming the toothed profile, a releasable device for selectively lowering the grinding wheel over a greater distance to lower the rear and tip profile of the selected tooth when the mechanism is operated. The machine comprises means for counting the number of teeth and for automatically selecting and operating the lowering mechanism.
(FR)
Lame de scie comportant des modules de 4 à 6 dents, dont le nombre dépend de la longueur de la lame, ayant au moins une dent sur 4, ou 5, ou 6, étant moins haute que les autres dents, de 6 à 8 dixièmes de millimètres. Procédé de fabrication d'une lame de scie à ruban à une ou deux faces de coupe comportant les étapes consistant: à former un ruban avec, sur les faces du côté correspondant à la surface de coupe, des dépouilles latérales; à former sur le bord de coupe les profils de denture à pas constant et de même hauteur; à écraser la pointe de chaque dent pour donner la voie; à affûter chaque dent; à rectifier le profil du dos et de la pointe d'au moins une dent sur n pour abaisser d'une valeur déterminée sa hauteur par rapport aux autres dents. Machine affûteuse pour exécuter ledit procédé, comportant sur le mécanisme à cames permettant de former le profil de la denture un dispositif débrayable permettant d'assurer une descente sélective sur une hauteur supérieure de la meule de façon à baisser le profil du dos et de la pointe de la dent sélectionnée lorsque le mécanisme est actionné. La machine comporte des moyens de compter le nombre de dents et de provoquer automatiquement la sélection et l'actionnement du mécanisme de descente.
