Schrämwerkzeug mit um einen zylindrischen Körper schraubenförmigCutting tool with a helical shape around a cylindrical body

verlaufenden Schneiden.running cutting edges.

Patentiert im Deutschen Reiche vom 27. September 1904 ab.Patented in the German Empire on September 27, 1904.

Gegenstand der Erfindung ist ein Schrämwerkzeug, bei dem um einen zylindrischen Körper schraubenförmig verlaufende Schneiden angeordnet sind.The invention relates to a cutting tool in which a cylindrical Body helically extending cutting edges are arranged.

Von den bekannten derartigen Schrämwerkzeugen unterscheidet sich das vorliegende auf der Zeichnung in Fig. ι in Ansicht und in Fig. 2 in einem Schnitt nach Linie a-b der Fig. ι dargestellte Werkzeug dadurch,The present tool shown in the drawing in FIG. 1 in view and in FIG. 2 in a section along the line from FIG.

ίο daß die Schneiden löffelartig, d. h. konkavkonvex gebogen sind. ίο that the cutting edges are spoon-like, d. H. are curved concavo-convex.

Durch diese Form der Schneiden, deren verlängerte Achsen nicht, wie üblich, radial zum zylindrischen Grundkörper verlaufen, sondern Sehnen des Grundkörpers bilden, soll ein Einfressen des Schrämwerkzeuges und damit eine bessere Wirkung erzielt werden. Das gewonnene Gut gelangt in die inneren Einhöhlungen der Schneiden und wird, wie üblich, infolge des schraubenförmigen Verlaufes der Schneiden aus dem Schräm entfernt.Due to this shape of the cutting edges, their extended axes are not, as usual, radial run to the cylindrical base body, but rather form tendons of the base body, The aim is to erode the cutting tool and thus achieve a better effect. The material obtained gets into the inner cavities of the cutting edges and, as usual, becomes helical as a result of the The course of the cutting edges has been removed from the bevel.
