KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Herstellung hinterdrehter Fräser war bisher nur unter Anwendung mehr oder weniger complicirter Apparate oder Specialmaschinen möglich; um nun derartige Fräser auf jeder gewöhnlichen Drehbank auf einfachste Weise herstellen zu können, soll nachstehend beschriebenes Verfahren dienen.The production of undercut milling cutters was previously only using more or less complicated apparatus or special machines possible; to now such milling cutters to be able to produce in the simplest way on any ordinary lathe is intended below the method described serve. Um an den einzeln eingesetzten Messern r die erforderliche Hinterdrehung herzustellen, werden dieselben in die in Fig. 1 und 2 dargestellte Hinterdrehscheibe derart eingesetzt, dafs die Schnittflächen α derselben zu einem sich ergebenden Durchmesser tangential stehen, so dafs die Peripherie der sämmtlichen Messer genau in einem Kreis liegt.In order r to produce the required undercut to the individually inserted blades are the same used in the in Fig. 1 and the rear hub illustrated 2 in such a way, that the sectional areas α thereof are tangent to an apparent diameter, the periphery of the Sämtliche diameter DAF exactly in a Circle lies. Werden nun die auf diese Art gedrehten Messer in den zum Fräsen benutzten Messerhalter (Fig. 3 und 4) eingespannt, so stehen die Schneidflächen α nicht mehr tangential, sondern radial, die hintere Kante η der Messer liegt nun nicht mehr in der Kreislinie, sondern entsprechend tiefer.If the knives rotated in this way are now clamped in the knife holder (Fig. 3 and 4) used for milling, the cutting surfaces α are no longer tangential but radial; the rear edge η of the knives is no longer in the circular line, but correspondingly deeper. Pateνt-Anspruch:Pateνt claim: Ein Halter zur Herstellung hinterdrehter Fräsmesser, gekennzeichnet dadurch, dafs die in einem Kopf (Fig. 3 und 4) radial einspannbaren Fräsmesser (r) in diesem Halter ~(Fig. 1 und 2) so schräg gehalten werden, dafs ihre die Schneidkanten begrenzenden und zu bearbeitenden Seitenflächen ein und derselben Rotationsfläche angehören.A holder for the production of undercut milling knives, characterized in that the milling knives (r) which can be clamped radially in a head (FIGS. 3 and 4) are held at an angle in this holder (FIGS. 1 and 2) so that they delimit the cutting edges and The side surfaces to be machined belong to the same surface of revolution.
