Verfallen zur Herstellung vieleckiger, scharfkantiger Gegenstände auf Dreh- blanken od. dgl.
Die Herstellung eckiger oder scharfkantiger Gegenstände auf Drehbänken od. dgl. unter Verwendung der derzeit bekannten Vorrichtungen ist unvollkommen. Das Werkzeug drückt, weil es das Werkstück an den Ecken nicht verlässt, die Kanten ab, es entstehen also in Wirklichkeit unscharf Kanten. Gemäss der Erfindung wird das Werkzeug beim Kantenwechsel, d. h. beim Übergang von einer Arbeit- fläche auf die andere, vom Werkstück entfernt und erst nachdem eine neue Arbeitsfläche in die Arbeitstellung gelangt ist, wieder in die Schnittstellung gebracht.
Steuert man durch Schablonen, Kurvenscheiben in Verbindung mit Hebeln u. dgl., in der Art wie es bei Automaten, Kopierdrehbänken usw. bekannt ist, den Drehbankschlitten nicht nur in der axialen Längsrichtung des Werkstückes, sondern auch in der dazu senkrechten Richtung, so weicht der Querschnitt des Werkstückes von der Kreisform ab. Steuert man noch gesondert das eingespannte Werkzeug, so kann man auch den Schnittwinkel desselben zum Werkstück stets unverändert halten. Diese Werkzeugsteuerung geschieht im vorliegenden Falle in der Weise, dass das Werkzeug beim Kantenwechsel für eine ganz kurze Zeitdauer das Werkstück verlässt, welche Dauer durch die Form und Grösse des Werkzeuges bzw. des Werkstückes bestimmt ist.
Das Ansetzen des Werkzeuges an die neue Fläche ist ähnlich wie bei einer Shapingmaschine und damit ist die Scharfkantigkeit gesichert.

Expired for the production of polygonal, sharp-edged objects on rotary bare or the like.
The production of angular or sharp-edged objects on lathes or the like using the currently known devices is imperfect. The tool presses off the edges because it does not leave the workpiece at the corners, so in reality the edges are blurred. According to the invention, the tool is used when changing edges, i. H. when moving from one work surface to the other, removed from the workpiece and only brought back into the cutting position after a new work surface has reached the work position.
If you control using templates, cams in connection with levers and the like. Like., In the manner as it is known from automatic machines, copier lathes, etc., the lathe slide not only in the axial longitudinal direction of the workpiece, but also in the direction perpendicular thereto, so the cross section of the workpiece deviates from the circular shape. If you control the clamped tool separately, you can always keep the cutting angle of the same to the workpiece unchanged. In the present case, this tool control takes place in such a way that the tool leaves the workpiece for a very short period of time when changing edges, which period is determined by the shape and size of the tool or the workpiece.
The application of the tool to the new surface is similar to that of a shaping machine and the sharp edges are thus ensured.
EMI1.1
Tool, which was previously in the position shown in dashed lines, just hit the work surface.
