KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. An den bekannten Schneidscheiben für Drehbänke, Hobel- und andere Metallbearbeitungsmaschinen bietet das Schleifen der Schneide insofern eine Schwierigkeit, als mit einem nafsgehenden Sandschleifstein die Rundung in der Tiefe des Schneidenausschnittes nicht nachgeschliffen werden kann, weil ein solcher Stein sich an den dafür verwendbaren Kanten schnell abnutzt. An Stelle eines solchen nafsgehenden Schleifsteines für das Schleifen der Schneidscheibenschneiden eine Schmirgelscheibe zu verwenden, ist deshalb nicht angängig, weil durch diese die Schneide selbst zu warm und daher unbrauchbar werden würde.On the well-known cutting discs for lathes, planers and other metalworking machines sharpening the cutting edge presents a difficulty insofar as it is difficult to grind with a moving one Sandstone the rounding in the depth of the cutting edge cannot be reground because such a stone wears out quickly on the edges that can be used for this purpose. In place of such an approaching one Sharpening stone to use an emery wheel for grinding the cutting disc edges, is therefore not accessible because it makes the cutting edge itself too warm and therefore too warm would become unusable. Um das Schleifen der Schneidscheiben besonders in der Rundung zu erleichtern, ist an solchen Schneidscheiben folgende in der beiliegenden Zeichnung dargestellte Einrichtung getroffen worden.,In order to facilitate the grinding of the cutting disks, especially in the rounding, is on such cutting disks following device shown in the accompanying drawing been hit., In die Schneidscheibe werden mit geringem Abstand von einander eine Anzahl Löcher a so gebohrt, dafs jedes derselben mit der tiefsten Stelle des Schneidenausschnittes zusammenfällt, wenn beim Schleifen der Schneide der Ausschnitt bis an das bezügliche Loch ausgedehnt worden ist. A number of holes a are drilled in the cutting disc at a small distance from one another so that each of them coincides with the deepest point of the cutting edge when the cutting has been extended to the hole in question during the grinding of the cutting edge. So lange ein solches Loch α im Bereich des Schleifsteins liegt, hat derselbe an dieser Stelle nicht zu wirken und unterliegt daher dessen Kante keiner Abnutzung; im Gegentheil bildet sich dieselbe infolge der naturgemäfsen Abnutzung beider sie begrenzenden Flächen schärfer aus und vermag daher in der Folge das zwischen zwei Löchern α α liegende Material besser zu bearbeiten.As long as such a hole α lies in the area of the grindstone, it has no effect at this point and its edge is therefore not subject to any wear; on the contrary, it is more sharply formed as a result of the natural wear and tear of both surfaces bounding it and is therefore able to work better on the material lying between two holes α α. Patent-Anspruch:Patent claim: Eine Schneidscheibe für ■ Metallbearbeitungszwecke, dadurch gekennzeichnet, dafs nahe an ihrem Umfange Löcher (a a) in geringer Entfernung von einander angebracht sind, um das Nachschleifen der Scheibe zu erleichtern.A cutting disc for metal working purposes, characterized in that holes (aa) are made close to its circumference at a short distance from one another in order to facilitate regrinding of the disc.
