KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Einrichtung gemäß der Erfindung hat den Zweck, flache Schneidwerkzeuge mittels
zweier sich in entgegengesetztem Sinne drehender Schleif walzen gleichmäßig zu schärfen.
Diese Schleifwalzen, die sich mit gleicher Geschwindigkeit drehen müssen, sind die eine
mit rechtsgehendem, die andere mit linksgehendem flachem Gewinde versehen und greifen
mit ihren Gewindegängen ineinander, so daß in dem Schnittwinkel zwischen den Walzen
flache Schneidwerkzeuge gleichmäßig geschliffen werden, ohne daß, wie bisher eine
Verschiebung des Werkstücks erforderlich wäre.The device according to the invention has the purpose of sharpening flat cutting tools by means of two grinding rollers rotating in opposite directions evenly.
These grinding rollers, which must rotate at the same speed, are one with a right-hand thread, the other with a left-hand flat thread and their threads interlock so that flat cutting tools are sharpened evenly at the cutting angle between the rollers without, as before a displacement of the workpiece would be required.
In der Zeichnung stellt Fig. ι die beiden Schleifwalzen α und b in Ansicht dar.In the drawing, Fig. Ι shows the two grinding rollers α and b in a view.
Fig. 2 zeigt das Walzenpaar im Schnitt mit dem zu schleifenden Schneidwerkzeug.Fig. 2 shows the pair of rollers in section with the cutting tool to be ground.
Die Schleifwalzen α und b können nach Bedarf so eingestellt werden, daß der Schnittwinkel der ineinander greifenden flachen Gewinde ein ganz spitzer wird, wodurch das zu schleifende Schneidwerkzeug nach einem sehr spitzen Keil geschliffen wird.The grinding rollers α and b can be adjusted as required so that the angle of intersection of the intermeshing flat thread becomes very acute, whereby the cutting tool to be ground is ground to a very sharp wedge.
Durch Auseinanderrücken der Walzen wird der Schärfwinkel entsprechend stumpfer.By moving the rollers apart, the sharpening angle becomes correspondingly more obtuse.
Die Drehrichtung der beiden Walzen muß, wie gesagt, eine entgegengesetzte sein; der Antrieb erfolgt zwangläufig durch Zahnräder.As I said, the direction of rotation of the two rollers must be opposite; the Drive is inevitably carried out by gears.
