Description

Segment von mit achsensenkrechter Fläche arbeitender Schleifscheibe Gegenstand der vorliegenden Erfindung ist ein Segment von mit achsensenkrechter Fläche arheitender Schleifscheibe, das als Schleifsegment ausgeführt ist. Das Neue an dem Schleifwerkzeug besteht darin, daß seine Außenfläche mit Einbuchtungen oder Längsrillen versehen ist, durch die eine wesentliche Verlängerung der Schleifkante erzielt wird. Insbesondere wird die Außenkante flach gewellt, wodurch bewirkt wird, daß die außen liegenden Teile dieser Wellen, die sich am eigentlichen Umfang der Scheibe befinden, als Vorschneider arbeiten, die die gröberen Teile des zu schleifenden Werkstückes fortnehmen, während die Kanten der nach innen sanft eingebogenen Wellen, das Nachschleifen bewirken. Es hat sich herausgestellt, daß dadurch eine außerordentliche Schonung der Schleifradkante hervorgerufen wird und auch eine geringere Erwärmung und Abnutzung des Schleifwerkzeuges eintritt.Segment of grinding wheel working with a surface perpendicular to the axis The present invention relates to a segment of with an axially perpendicular Surface arheitender grinding wheel, which is designed as a grinding segment. The new on the grinding tool is that its outer surface with indentations or Longitudinal grooves are provided through which a substantial extension of the grinding edge is achieved. In particular, the outer edge is corrugated flat, which has the effect of that the outer parts of these waves, which are located on the actual circumference of the Disc are located, working as a rough cutter, which the coarser parts of the to be ground Remove the workpiece while the edges of the waves gently curved inwards, cause regrinding. It has been found that this is an extraordinary Protection of the grinding wheel edge is caused and also less heating and wear of the grinding tool occurs.

Zweckmäßig wird dabei: die äußere Kante in bekannter Weise gehärtet, um sie noch widerstandsfähiger zu machen.The following is useful: the outer edge is hardened in a known manner, to make them even more resilient.

Man hat zwar schon vorgeschlagen, Schleifkörper mit von außen her eingeschnittenen tiefen Rillen zu versehen. Diese verlaufen aber nicht wellenförmig, sondern sind scharf und eckig eingeschnitten, was den Nachteil hat, daß die Grundflächen der rechteckigen Nuten an ihren Kanten überhaupt nicht zur Einwirkung kommen, weil die ganze Schleifarbeit von den stehengebliebenen Außenkanten geleistet werden muß. Es entsteht auch zwischen ZVerkstück und Schleifscheibe ein keilförmiger Spalt, in den sich der Schleifstaub einsetzt und die Scheibe verschmiert. Dazu kommt noch, daß ein derartiger Schleifkörper bei seiner Herstellung unzulässige Spannung erhält, :die sehr leicht zu Sprüngen und zum Zerreißen des Schleifkörpers führen. Auch bröckeln die Seitenflächen der Rille im Betriebe sehr leicht ab.It has already been proposed to use abrasives from the outside cut deep grooves. But these are not wavy, but are cut sharp and angular, which has the disadvantage that the base areas of the rectangular grooves at their edges do not have any effect at all because all the grinding work has to be done by the remaining outer edges. There is also a wedge-shaped gap between the Z-workpiece and the grinding wheel, in which the grinding dust settles and smears the disc. Additional to that, that such a grinding wheel receives inadmissible tension during its manufacture, : which easily lead to cracks and tearing of the grinding wheel. Crumble too the side surfaces of the groove in operation very easily.

Diese Nachteile werden durch die wellenförmigen Vertiefungen bei dem Schleifsegment nach der vorliegenden Erfindung vermieden, da hier das Vorschneiden durch die äußeren Teile,der Wellen allmählich in das Nachschleifen durch die inneren Teile der Wellen übergeht. Auch unterstützen die wellenförmigen Vertiefungen -die Ableitung des Schleifschlammes sowie die durch Wasser oder Luft erfolgende Abkühlung.These disadvantages are due to the wave-shaped depressions in the Avoided grinding segment according to the present invention, since here the pre-cutting through the outer parts, the shafts gradually in the regrinding through the inner Parts of the waves pass over. The wave-shaped depressions also support the Discharge of the grinding sludge as well as the cooling carried out by water or air.

Eine beispielsweise Ausführungsform eines derartigen Schleifkörpers ist in der beiliegenden Zeichnung dargestellt: Die äußere Fläche des Schleifsegmentes e ist mit Wellungen c versehen. Die äußere Fläche d dieser Wellungen wird, wie an sich bekannt ist, zweckmäßig mit besonderer Härte ausgeführt.An example embodiment of such a grinding wheel is shown in the accompanying drawing: The outer surface of the grinding segment e is provided with corrugations c. The outer surface d of these corrugations becomes, as at is known, expediently executed with special hardness.
