Description
W technice dentystycznej do oddziela¬ nia zebów, jak równiez do ich szlifowania stosowane sa narzedzia w ksztalcie kraz¬ ków lub plaskich prostokatnych plytek, pokrytych cienka warstwa srodka szlifuja¬ cego.Podlug niniejszego wynalazku plaskie boki takich narzedzi, sluzace do szlifowa¬ nia, posiadaja szereg otworów, zas waskie krawedzie tych narzedzi, sluzace do prze¬ cinania, sa zaopatrzone w zeby, wskutek czego narzedzia takie moga dzialac rów¬ niez jak pilniki. Ostre krawedzie otworów, znajdujacych sie na szlifujacej bocznej po¬ wierzchni narzedzia, jak równiez zeby na waskich krawedziach tego narzedzia slu¬ zace do pilowania zwiekszaja znacznie wy¬ dajnosc narzedzia przy skrawaniu, wsku¬ tek czego robota zapomoca takiego narze¬ dzia moze byc wykonywana latwiej i pre¬ dzej, niz stosowanemi dotychczas podobne- mi narzedziami, które oprócz tego wskutek swych niezbyt szorstkich powierzchni sa trudne do umocowania w uchwytach.Na zalaczonym rysunku przedstawiony jest przyklad wykonania wynalazku.Fig. 1 przedstawia zaopatrzony w o- twory i zeby krazek do szlifowania, a fig. 2 — plytke prostokatna do szlifowania.Na obydwóch tych figurach wspomnia¬ ne otwory oznaczone sa litera a, zas ze¬ by — litera b.Ksztalt, zarówno jak uklad i podzial tych otworów i zebów moze byc dowolny, przyczem narzedzie sluzace do szlifowania moze równiez posiadac tylko boczne otwo¬ ry bez zebów na krawedziach lub tylko zeby bez otworów. PL PLIn dental technology, tools in the shape of a disc or a flat rectangular plate coated with a thin layer of abrasive are used for the separation of teeth as well as for grinding them. the series of holes, and the narrow edges of these shearing tools, are provided with teeth, so that the tools can function like files. The sharp edges of the holes on the grinding side of the tool as well as the teeth on the narrow edges of this sawing tool significantly increase the efficiency of the cutting tool, so that the work of such a tool can be carried out more easily and sooner than with similar tools used hitherto, which, moreover, due to their not very rough surfaces, are difficult to attach in the holders. The attached drawing shows an example of the invention. 1 shows a grinding disc with holes and teeth, and FIG. 2 shows a rectangular grinding plate. In both of these figures, the holes are marked with the letter a, and the teeth are marked with the letter b. the distribution of these holes and teeth may be arbitrary, whereas the grinding tool may also have only side holes with no teeth on the edges or only teeth without holes.
