Ein Schleifteller dieser Art ist in der AT-PS 378 345 beschrieben.A grinding plate of this type is described in AT-PS 378 345.
Derartige Schleifteller werden insbesondere bei der Gesteinsbearbeitung eingesetzt.Such grinding plates are used in particular in stone processing.
Aufgabe der Erfindung ist es, einen Schleifteller zu entwickeln, mit dem sowohl stirnseitig als auch mantelseitig in einem Arbeitsgang geschliffen werden kann. Eine weitere Aufgabe der Erfindung besteht darin, einen derartigen Schleifteller so zu verbessern, daß mit ihm gegenüber herkömmlichen Schleiftellern höhere Abtragsleistungen erzielt werden können.The object of the invention is to develop a sanding plate with which grinding can be carried out in one operation both on the face side and on the casing side. Another object of the invention is to improve such a grinding plate so that higher removal rates can be achieved with it compared to conventional grinding plates.
Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß anschließend an die Schleifsegmente ein Abriebring vorgesehen ist, der mit der der Nabe abgewandten Seite des Trägerkörpers verbunden ist, der von geschäumtem Kunststoff mit Füllstoffen gebildet wird und der radial vorspringende Abschnitte aufweist, die zwischen die mit Abstand voneinander angeordneten Schleifsegmente ragen.The object of the invention is achieved in that an abrasion ring is provided next to the grinding segments, which is connected to the side of the carrier body facing away from the hub, which is formed by foamed plastic with fillers and which has radially projecting sections between them at a distance from one another arranged grinding segments protrude.
Der Abriebring trägt zur Stabilisierung des Werkzeuges beim stirnseitigen Schleifen bei.The abrasion ring helps to stabilize the tool when grinding at the front.
Einerseits hat sich gezeigt, daß ein erfindungsgemäßer Schleifteller beim stirnseitigen Schleifen die vierfache Abtragsleistung eines herkömmlichen Schleiftellers mit in etwa vergleichbaren Rauhtiefwerten erbringt. Andererseits läßt sich der erfindungsgemäße Schleifteller als Kombinationsfräser einsetzen, d. h. es kann mit ihm sowohl stirnseitig als auch mantelseitig geschliffen werden.On the one hand, it has been shown that a grinding plate according to the invention produces four times the removal capacity of a conventional grinding plate with roughly comparable roughness values when grinding on the face side. On the other hand The grinding plate according to the invention can be used as a combination milling cutter, ie it can be used to grind both the front and the casing side.

Um eine höhere Standzeit des Abriebringes zu erreichen ist in einem Ausführungsbeispiel der Erfindung vorgesehen, daß der Kunststoff des Abriebringes Polyurethan ist und die Füllstoffe zumindestens teilweise von Siliziumkarbid gebildet werden.In order to achieve a longer service life of the wear ring, one embodiment of the invention provides that the plastic of the wear ring is polyurethane and that the fillers are at least partially formed by silicon carbide.
Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, daß der Trägerkörper einen zylindrischen Rand aufweist, der vom Abriebring umfaßt wird. Auf diese Art wird ein guter Verbund des Abriebringes mit dem Trägerkörper erzielt.Another embodiment of the invention provides that the carrier body has a cylindrical edge which is surrounded by the abrasion ring. In this way, a good bond between the wear ring and the carrier body is achieved.
Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, daß der Abriebring innen konisch ausgeführt ist, wobei der Abriebring an der schleifseitigen Stirnseite am breitesten ist, und daß der Trägerkörper im Nabenbereich einen mittigen Zulaufkanal für die Kühlflüssigkeit aufweist, daß dieser Zufuhrkanal als Sackloch ausgeführt ist, das schleifseitig in einem zylindrischen Ansatz endet, der mindestens ein radiales Austrittsloch für die Kühlflüssigkeit aufweist.Another embodiment of the invention provides that the abrasion ring is conical on the inside, the abrasion ring being the widest on the end face on the grinding side, and that the carrier body has a central inlet channel for the cooling liquid in the hub area, that this inlet channel is designed as a blind hole, which ends on the grinding side in a cylindrical projection which has at least one radial outlet hole for the cooling liquid.
Im Abriebring sind radial verlaufende Durchgangskanäle für ein Kühlmittel vorgesehen.Radially extending through-channels for a coolant are provided in the wear ring.
Durch die konische Ausführung des Abriebringes wird die Kühlflüssigkeit lange im Bereich des Werkzeuges gehalten. Dieser Effekt kann auch dadurch verbessert werden, daß der zylindrische Ansatz an seinem freien Ende mit einem äußeren Ablenkring für die Kühlflüssigkeit versehen ist.The conical design of the wear ring keeps the coolant in the area of the tool for a long time. This effect can also be improved in that the cylindrical extension is provided at its free end with an outer deflection ring for the cooling liquid.

Die Schleifsegmente 2 sind relativ schmal ausgeführt, d. h. ihre Länge in der Umfangsrichtung ist wesentlich größer als die Breite in radialer Richtung des Schleiftellers. Beim stirnseitigen Schleifen ist daher der von den Schneidsegmenten 2 gebildete Schneidring relativ schmal, wodurch sichergestellt ist, daß die äußere Schneidkante K ständig scharf ist.The
An die Schleifsegmente 2 schließt der Abriebring 3 an. Der Abriebring 3 ist mit der der Nabe 12 abgewandten Seite des Trägerkörpers 1 verbunden. Die Schleifsegmente 2 befinden sich im Abstand zueinander, sodaß zwischen den Schleifsegmenten 2 Abschnitte 4 des Abriebringes 3 ragen. Im Bereich der Abschnitte 4 befinden sich die Durchlaßkanäle 5 für ein Kühlmittel, die den Abriebring 3 und den Rand 6 des Trägerkörpers 1 annähernd radial durchlaufen.The

The grinding plate according to the invention is also suitable for grinding curved edges and for grinding curves inside (FIGS. 8, 9).
Die Schäumung zwischen den Schleifsegmenten 2, d. h. die Abschnitte 4 bewirken eine Dämpfung während des Schleifens, d. h. es wird ein ratterfreier Lauf erzielt.The foaming between the
Im gezeigten Ausführungsbeispiel ist der Schleifteller außen mit einem zylindrischen Mantel versehen. Es könnte jedoch auch ein konischer Schleifring vorgesehen sein.In the exemplary embodiment shown, the grinding plate is provided on the outside with a cylindrical jacket. However, a conical slip ring could also be provided.
