Description

Schleifwerkzeuge für zahnärztliche Zwecke o. dgl. Die in der Zahnpraxis gebräuchlichen Schleifwerkzeuge (Schleifscheiben, Kegel, Räder o. dgl.) sind meist so ausgeführt, daß die ganze Schleiffläche mit dem Schleif- material Diamant, dgl., be- legt ist. Ist die Schleiffläche durch kleine Aussparungen unterbrochen, so ist doch immer der äußere Rand des Schleifwerkzeugs ganz mit dem Schleifmaterial belegt. Durchlaufende Nuten aber, wie solche bei manchen Schleifkörpern zur Holzbearbeitung in der dicken Schleifmaterialschicht selbst vorgesehen sind und die dem besseren Absaugen des Schleifstaubes durch Exhaustoren dienen sollen, können in dem dünnen Schleifmaterialbelag der kleinen zahnärztlichen Schleifwerkzeuge nicht angebracht werden.Grinding tools for dental purposes or the like. The grinding tools commonly used in dental practice (grinding disks, cones, wheels, etc.) are usually designed in such a way that the entire sanding surface with the sanding material diamond, like. is laying. If the grinding surface is interrupted by small recesses, the outer edge of the grinding tool is always completely covered with the grinding material. However, continuous grooves, such as those provided in the thick layer of abrasive material itself in some grinding tools for woodworking and which are intended to improve the suction of the grinding dust through exhaustors, cannot be made in the thin abrasive material coating of the small dental grinding tools.

Die ununterbrochen belegten Flächen der zahnärztlichen Schleifwerkzeuge haben den Nachteil, daß sie bei großen Umdrehungszahlen und besonders beim Schleifen der natürlichen Zähne im Munde eine starke Erhitzung hervorrufen. Hinzu kommt noch, daß die voll belegte schleifende Fläche schon nach kurzem Gebrauch und auch bereits während des Gebrauchs von dem Schleifstaub zugesetzt wird, was die Schleifkraft erheblich verringert und eine längere Schleifdauer erforderlich macht.The continuously occupied surfaces of dental grinding tools have the disadvantage that they work at high speeds and especially when grinding of the natural teeth in the mouth cause intense heating. Additionally, that the fully covered grinding surface already after a short use and also already during use of the grinding dust is added, which increases the grinding force significantly reduced and requires a longer grinding time.

Es ist daher für zahnärztliche Zwecke wünschenswert, ein Schleifwerkzeug zu schaffen, das diese Nachteile nicht besitzt.It is therefore desirable for dental purposes to have an abrasive tool to create that does not have these disadvantages.

Die Erfindung löst die Aufgabe ihn sehr einfacher und vollkommener Weise dadurch, daß die schleifenden Flächen durch nicht mit Schleifmaterial belegte Flächen unterbrochen werden. Auf der Zeichnung sind mehrere Ausführungsformen des Erfindungsgegenstandes veranschaulicht, und zwar zeigt: Abb: i den Grundriß einer Schleifscheibe, Abb. 2 dieselbe in Seitenansicht, Abb. g die Ansicht eines Schleifkegels und Abb. ,4 die Ansicht eines Schleifrädchens. Bei allen 'Ausführungsarten ist die schleifende Fläche a durch besondere Flächen b, die nicht mit Schleifmaterial belegt sind, unterbrochen. Die Begrenzungslinien c der belagfreien Flächen b können (Abb. i und 3 ) krummlinig öder (Abb.4) gradlinig oder sonstwie gestaltet sein. Immer wird die schleifende Fläche a, beispielsweise auch bei dem Werkzeug nach Abb. i die äußere Randfläche, unterbrochen von belagfreien Flächen b, die den abfallenden Schleifstaub aufnehmen und aus dem sich drehenden Werkzeug herausschleudern.The invention solves the problem very simply and perfectly Way in that the abrasive surfaces are not covered with abrasive material Surfaces are interrupted. On the drawing are several embodiments of the Subject of the invention illustrated, namely shows: Fig: i the floor plan of a Grinding wheel, Fig. 2 the same in side view, Fig. G the view of a grinding cone and Fig. 4 is a view of a grinding wheel. In all 'versions, the Abrasive surface a by special surfaces b that are not covered with abrasive material are interrupted. The boundary lines c of the uncovered areas b can (Fig. i and 3) curvilinear or straight (Fig.4) or designed in some other way. always the grinding surface a, for example also with the tool according to Fig. i the outer edge surface, interrupted by surface-free surfaces b, the sloping Pick up grinding dust and throw it out of the rotating tool.

Durch die Erfindung wird die Schleiffläche a gerade an den meist benutzten Stellen durch belagfreie Flächen b unterbrochen, die den abfällenden Schleifstaub aufnehmen und dann abgeben, so daß die Werkzeuge fest und schleifkräftig bleiben, ohne den zu schleifenden Zähn zu erhitzen und Schmerzen-zu verursachen.With the invention, the grinding surface a is used most often Places interrupted by non-covering surfaces b, which contain the falling sanding dust pick up and then release, so that the tools remain firm and grindable, without heating the tooth to be ground and causing pain.
