Description

  

  Schleifwerkzeug, insbesondere für zahnärztliche Zwecke.    Zum Separieren und     Beschleifen    von Zäh  nen werden in der Zahntechnik     scheiben-    und  streifenförmige Schleifwerkzeuge verwendet,  die aus einem einseitig oder beidseitig mit  einer Schleifmittelschicht bedeckten Träger  aus dünnem Stahlblech     etc.    bestehen.  



  Gemäss der Erfindung ist die Schleif  fläche des vorliegenden Schleifwerkzeuges  gelocht und am Rande gezahnt, so     dass    das  selbe auch als Säge benutzbar ist. Die     scharf-          randigen    Löcher in der Schleiffläche, sowie  die Sägezähne erhöhen die     Schneidfähigkeit     des     Schleifwerkzeuges    wesentlich, so dass die  Schleifarbeit schneller und leichter als mit  den bisher gebräuchlichen Schleifscheiben  und Schleifstreifen von statten geht, wobei  der sägende Schnitt ausserdem das lästige  Festklemmen dieser Werkzeuge verhindert.  



  In der Zeichnung sind zwei Ausfüh  rungsbeispiele des Erfindungsgegenstandes  dargestellt, es     zeigt:          Fig.    l eine gelochte und gezahnte Schleif  scheibe, und         Fig.    2 einen ebensolchen Schleifstreifen.  Bei beiden Beispielen, deren Träger aus  dünnem Stahlblech besteht und einseitig oder  beidseitig mit einer Schleifmittelschicht be  deckt ist, sind die Löcher in der Schleiffläche  mit     a    und die Zähne am Rande mit<I>b</I> be  zeichnet. Die Gestaltung, Anordnung und  Verteilung der Löcher und der     Sägezähne     kann beliebig gewählt werden.



  Grinding tools, in particular for dental purposes. To separate and grind teeth, disc-shaped and strip-shaped grinding tools are used in dental technology, which consist of a carrier made of thin sheet steel, etc., which is covered on one or both sides with an abrasive layer.



  According to the invention, the grinding surface of the present grinding tool is perforated and serrated on the edge, so that it can also be used as a saw. The sharp-edged holes in the grinding surface as well as the saw teeth increase the cutting ability of the grinding tool significantly, so that the grinding work is faster and easier than with the grinding discs and grinding strips that have been used up to now, whereby the sawing cut also prevents the annoying jamming of these tools.



  In the drawing, two Ausfüh approximately examples of the subject matter of the invention are shown, it shows: Fig. 1 a perforated and toothed grinding disc, and Fig. 2 is a similar abrasive strip. In both examples, the backing of which is made of thin sheet steel and is covered on one or both sides with an abrasive layer, the holes in the grinding surface are marked with a and the teeth on the edge with <I> b </I>. The design, arrangement and distribution of the holes and the saw teeth can be chosen as desired.
