     L, - : don   bisher gebräuchlichen Nabenbohrmaschinen ist die Bohrstange in einem Gestell gelagert, welches auf einer Seite der Nabe befestigt wird. Diese Anordnung hat aber den grossen   Nachthoil,   dass die Bohrstange einseitig geführt ist, wodurch der Gang des am Ende der letzteren angebrachten Schneidmessers umso unsicherer wird, je weiter os sich von   der Führung entfernt,   weshalb sich diese Maschinen für ein genaueres Bohren

 dargestellt. 



   Dieselbe besteht, wie bekannt, aus einer Bohrstange a, deren rückwärtiger Theil ein Gewinde trägt und durch die zweitheilige Mutter d geführt wird.   Letztere ruht   mit ihrem   Untertheil in   der Bohrung der Scheibe J und ist durch   Führungsstifte   mit dem Obertheil verbunden, der mittelst Schraubenspindel k zwecks schneller Herausnahme und Einstellung der Bohrspindel gehoben bezw. gesenkt werden kann. Auch beim Conischdrehen ist es erforderlich, den oberen Lagerthcil etwas zu heben. Die Scheibe j kann mittelst der Schrauben m genau centrisch auf einer Seite der Nabe n befestigt werden.

 Lasche 'geführt, die an der Scheibe b mittelst Stellschraube h höher oder tiefer gestellt werden kann. zu welchem Behufe auch die Scheibe b einen   entsprechenden Schlitz t'auf-     wuist. Die Scheibe b   ist in der Scheibe i drehbar gelagert. die wieder an der zweiten Seite der Nabe mittelst Stellschrauben l centrisch befestigt werden kann. Das Schneid-   messer e   ist in bekannter Art auswechselbar in der Bohrstange a befestigt.

   Bei der in Fig. 1 dargestellten Anordnung ist die Maschine zum   Cylindrischdrehen   hergerichtet ; soll conisch gedreht werden, so wird wie bekannt das Lager d etwas gelüftet und die Bohrstange n an der Vorderseite der Nabe, entsprechend dem zu bohrenden conischen Loche, durch Verstellen der Lasche f mittelst Stellschraube h aus dem Mittel gebracht.

 EMI1.1
 



     L, -: on the hub drilling machines commonly used up to now, the drill rod is mounted in a frame which is attached to one side of the hub. However, this arrangement has the big night hole that the boring bar is guided on one side, which makes the operation of the cutting knife attached to the end of the latter all the more unsafe the further away from the guide, which is why these machines are used for more precise drilling

 shown.



   As is known, it consists of a drill rod a, the rear part of which is threaded and passed through the two-part nut d. The latter rests with its lower part in the bore of the disc J and is connected by guide pins to the upper part, which is lifted or raised by means of the screw spindle k for the purpose of quicker removal and adjustment of the drilling spindle. can be lowered. Even when turning a cone, it is necessary to lift the upper bearing part a little. The disk j can be fastened exactly centrically on one side of the hub n by means of the screws m.

   On the other
 EMI1.3
 Tab ', which can be set higher or lower on the disc b using the adjusting screw h. for whatever reason the disk b also has a corresponding slot t '. The disk b is rotatably mounted in the disk i. which can again be fixed centrically on the second side of the hub by means of adjusting screws. The cutting knife e is fastened in a known manner in an exchangeable manner in the boring bar a.

   In the arrangement shown in Figure 1, the machine is prepared for cylindrical turning; if it is to be turned conically, the bearing d is lifted somewhat, as is known, and the boring bar n at the front of the hub, corresponding to the conical hole to be drilled, is brought out of the center by adjusting the tab f using the adjusting screw h.
