Description
Beim Fräsen von Gewinden tritt der Übelstand auf, daß die Zahnflanken des Werkstückes nicht sauber ausfallen, sondern Risse und Löcher zeigen, die von den Spänen herrühren, welche an dem Fräser hängengeblieben sind.When milling threads, the disadvantage arises that the tooth flanks of the workpiece do not turn out clean, but show cracks and holes from the chips, which got stuck on the cutter.
Dieser Nachteil soll durch den Gegenstand der Erfindung dadurch beseitigt werden, daß ein Abstreifer vorgesehen ist, der dem Werkstück vorgelagert ist und die dem Fräser anhaftenden Späne abstreift, so daß er mit ganz sauberen Schneidflanken das Werkstück fräst. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.This disadvantage is to be eliminated by the subject matter of the invention in that a scraper is provided which is positioned in front of the workpiece and which adheres to the milling cutter Strips off chips so that it mills the workpiece with very clean cutting edges. An exemplary embodiment of the invention is shown schematically in the drawing.
Abb. ι zeigt eine Seitenansicht vor der Bearbeitung und Abb. 2 einen Schnitt nach Linie 2-2 der Abb. 3 bei Bearbeitung des Werkstückes. Abb 3 ist ein Schnitt nach 3-3 der Abb. 2, in Richtung des Pfeiles gesehen.Fig. Ι shows a side view before processing and Fig. 2 shows a section along line 2-2 of Fig. 3 when machining the workpiece. Fig 3 is a section along 3-3 of Fig. 2, seen in the direction of the arrow.
Zwischen dem Werkstück 1 und dem Fräser 2 wird vor Beginn des Fräsens ein der Länge des Fräsers entsprechender Abstreifer 3 vorgesehen, der in einer an der MaschineBetween the workpiece 1 and the milling cutter 2, a is before the start of milling Length of the cutter corresponding to the scraper 3 provided in one on the machine

Beginnt man mit dem Fräsen, dann wird der Fräser 2 gegen das Werkstück 1 geführt. Da aber diesem der Abstreifer 3 vorgelagert ist, so fräst das Werkzeug 2 zunächst das Profil 6 seiner Zähne in den Abstreifer 3. Bleiben nun Späne an dem Fräser hängen, so werden sie durch den Abstreifer 3 entfernt, so daß man stets ein sauberes Werkstück erhält. If you start milling, the milling cutter 2 is guided against the workpiece 1. However, since this is preceded by the scraper 3, the tool 2 first mills the Profile 6 of its teeth in the scraper 3. If chips now stick to the cutter, see above they are removed by the scraper 3, so that you always get a clean workpiece.
