Description

Zum Schneiden von Gewinden und ähnlichen Profilen auf der Drehbank werden bekanntlich nacheinander Schrupp- und Sdüichtstrehler benutzt, die auch in einem drehbaren, mit Schrupp- und Schliichtstählen besetzten runden Messerkopf vereinigt werden können, so daß sie durch Drehung- des Messerkopfes nacheinander an das. Werkstück herangeführt werden. Hierbei erfolgt die Schrupp- undFor cutting threads and similar profiles on the lathe are known one after the other roughing and sealing chasers used, which also in a rotatable, with roughing and finishing steels round cutter head can be combined so that they can be turned by turning the cutter head one after the other to the workpiece. The roughing and

ίο Schlichtarbeit in getrennten Arbeitsgängen. Benutzt man einen der bekannten Strähler, dessen Schrupp- und Schlichtzahn gleichzeitig zur Arbeit kommen, so werden die Sehneidhaltigkeit des, Werkzeuges und die Sauberkeit der Arbeit stark beeinträchtigt.ίο Finishing work in separate work steps. If you use one of the well-known Strähler, its roughing and finishing teeth at the same time When you come to work, the sharpness of the tool and the cleanliness become important severely impaired work.

Es ist auch bekannt, Schrupp- -und Schlichtstähle mit kreisförmig ausgebildeten Schneiden, die verschieden tief in das Werkstück dringen sollen, in einer Kluppe einzuspannen.It is also known to use roughing and finishing steels with circular cutting edges, which should penetrate the workpiece to different depths, to be clamped in a clip.

Bei diesen Werkzeugen kann aber der kreisförmig ausgebildete Schruppzahn nur radial an das Werkstück herangeführt werden, und eine Regelung der Aufeinanderfolge von Schruppen und Schlichten ist nicht so leicht möglich.With these tools, however, the circular roughing tooth can only be radial are brought up to the workpiece, and a control of the sequence of Roughing and finishing is not that easy.

Gemäß der Erfindung werden diese Übelstände umgangen, indem das neue Werkzeug einen in der Längsrichtung des Werkzeuges und in der Richtung gegen das Werkstück vorspringenden Schruppzahn· mit gerader Schneidbrust besitzt, der tangential an das sich drehende Werkstück herangeführt wird, und einen zurückspringenden, kreisförmig ausgebildeten Schlichtzahn, der nach dem Schruppzahn zur Wirkung kommt und wesentlieh radial dem sich drehenden Werkstück genähert wird.According to the invention, these inconveniences are circumvented by the new tool one in the longitudinal direction of the tool and one in the direction against the workpiece has a protruding roughing tooth with a straight cutting face that is tangential to the rotating workpiece is brought up, and a recessed, circular shape Finishing tooth, which comes into effect after the roughing tooth and which is essential is approached radially to the rotating workpiece.

Ein Ausführungsbeispiel des Strehlers nach der Erfindung ist in der Zeichnung dargestellt. An embodiment of the chaser according to the invention is shown in the drawing.

Abb, ι zeigt das in Form einer Backe ausgebildete Gewindeschneidwerkzeug α und den zu bearbeitenden Gegenstand b in der Anfangsstellung. Das Werkzeug α Hegt mit dem Schruppzahn c an dem Werkstück ö. Beim Drehen des Werkstückes schneidet der Schruppzahn in das Werkstück ein und nähert sich in der Pfeilrichtung der Werkstückachse, wodurch auch der Schlichtzahn d dem Werkstück & immer näher kommt, bis er in der in Abb. 2 veranschaulichten Stellung zu. arbeiten beginnt.Fig, ι shows the thread-cutting tool α , designed in the form of a jaw, and the object to be machined b in the initial position. The tool α lies with the roughing tooth c on the workpiece ö. When the workpiece is turned, the roughing tooth cuts into the workpiece and approaches the workpiece axis in the direction of the arrow, whereby the finishing tooth d also comes closer and closer to the workpiece & until it is in the in Fig. 2 position illustrated. work begins.
