Nachdem auf der Drehbank mit dem Hohlbohrkopf der Kern des Geschosses etc.. auf die nöthige Tiefe eingebohrt ist, wird die Bohrstange zurückgezogen, die Hohlbohrmesser werden entfernt (welche doch jedesmal zum Schleifen entfernt werden müssen), und man schiebt die Hohlbohrstange mit erneuertem Abstechmesser, Fig. 6 und 7, wieder so tief, so weit der Kern abgestochen werden soll, hinein.After the core of the bullet etc .. on the lathe with the hollow drill head the necessary depth has been bored, the boring bar is withdrawn, the hollow boring knives are removed (which have to be removed every time for grinding), and you pushes the hollow boring bar with the renewed parting knife, Fig. 6 and 7, so deep again, as far as the core is to be cut into.
Das rechtwinkelige Abstechen des Kernes geschieht nun auf folgende Weise:The right-angled parting of the core is now done as follows:
Indem man den Hebel e hebt, drückt der excentrische Theil der Welle d den Messerhalter c mit dem Messer α gegen den Kern und schneidet sich auf diese Weise rechtwinkelig in den Kern. Nachdem man nun glaubt, den Kern tief genug angeschnitten zu haben, dreht man den Hebel e in seine erste Lage zurück und zieht die Hohlbohrstange zurück.By lifting the lever e , the eccentric part of the shaft d presses the knife holder c with the knife α against the core and in this way cuts itself at right angles into the core. Now that you think you have cut the core deep enough, you turn the lever e back into its first position and pull back the hollow boring bar.
Jetzt wird, wie aus Fig. 3 ersichtlich, auf den Kern des Cylinders ein Klemmeisen g gesetzt, welches auf der anderen Seite auf dem Untersatz /2, welcher lose auf die Drehbankwange aufgesetzt ist, aufruht. Vermittelst der Spannschraube i wird nun das Klemmeisen so weit heruntergeschraubt, bis der Kern bricht.Now, as can be seen from Fig. 3, a clamping iron g is placed on the core of the cylinder, which rests on the other side on the base / 2, which is loosely placed on the lathe cheek. With the help of the tensioning screw i , the clamp iron is now screwed down until the core breaks.
Nachdem nun der abgebrochene Kern, die Schraube, das Klemmeisen und der Untersatz beseitigt sind, wird der zum Federn eingerichtete geschlitzte Schaft des Messerkopfes, Fig. 4 und 5, in den Hohlbohrkopf, Fig. 2, eingeschoben, und zwar so, dafs die Vertiefungen der beiden Köpfe, um ein Drehen zu verhindern , in einander greifen. Mittelst der Schraube k wird die konische Büchse / so weit in den geschlitzten Theil eingezogen, dafs derselbe nun fest mit Fig. 2 verbunden ist. Darauf wird das Bodenmesser m in den Messerkopf eingesetzt und durch die Schraube η festgehalten. Das Ganze wird zuletzt in den Cylinder eingeschoben und die weitere Bearbeitung des Bodens vorgenommen. Die Wasserzuführung zu dem Messer m geschieht von innen und tritt das Wasser durch die durchbohrte Schraube k an die Schneide des Messers m. After the broken core, the screw, the clamping iron and the base have been removed, the slotted shaft of the cutter head, Fig. 4 and 5, which is set up as a spring, is pushed into the hollow drill head, Fig. 2, in such a way that the indentations of the two heads interlock to prevent turning. By means of the screw k the conical sleeve / is drawn into the slotted part so far that it is now firmly connected to FIG. The bottom knife m is then inserted into the knife head and held in place by the screw η . The whole thing is finally pushed into the cylinder and the further processing of the soil is carried out. The water is supplied to the knife m from the inside and the water passes through the pierced screw k to the cutting edge of the knife m.
