Description

Schleifwerkzeug, insbesondere für zahnärztliche Zwecke. Zum Separieren und Beschleifen von.

For separating and grinding of. Teeth. are shingled in dental technology - and strip-shaped Abrasive tools used that consist of, one, covered with an abrasive layer Beams made of steel or the like.

Gemäß der Erfindung ist die Schleiffläche solcher Schleifwerkzeuge gelocht und am Rande gezahnt, so daß sie auch als Säge benutzbar sind. Die scharfrandigen Löcher in dex Schleiffläche sowie die Sägezähne erhöhen die Schneidfähigkeit des Schleifwexkzeuges ganz wesentlich, so daß die Schleifarbeit schneller und leichter als mit den - bisher gebräuchlichen Schleifscheiben und Schleifstreifen vonstatten. geht, wobei der sägende Schnitt außerdem das lästige- Festklemmen dieser Werkzeuge verhindert.According to the invention, the grinding surface is such grinding tools perforated and serrated on the edge so that they can also be used as a saw. The sharp-edged ones Holes in the grinding surface as well as the saw teeth increase the cutting ability of the Schleifwexkzeuges quite essential, so that the grinding work faster and easier than with the previously common grinding wheels and grinding strips. goes, with the sawing cut also the annoying clamping of these tools prevented.

Auf der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt, es zeigt: Abb. r eine gelochte und gezahnte Schleifsc'helbe und Abb. z einen ebensolchen Schleifstreifen. Bei beiden Beispielen sind die Löcher in der Schleiffläche mit a und die- Zähne am Rande mit b bezeichnet. Die Gestaltung, Anordnung und Verteilung dieser Löchera und Sägezähne b kann beliebig gewählt werden. Aud,,,i kann gegebenenfalls die Schleiffläche nur gezahnt oder nur gelocht sein.The drawing shows two exemplary embodiments of the subject matter of the invention shown, it shows: Fig. r a perforated and serrated grinding wheel and Fig. z such a sanding strip. In both examples, the holes are in the Grinding surface with a and the teeth on the edge with b. The design, arrangement and distribution of these holes a and saw teeth b can be chosen arbitrarily. Aud ,,, i If necessary, the grinding surface can only be toothed or only perforated.
