Description

Die Erfindung bezieht sich auf einen Schleifteller mit einem Trägerkörper mit einer mittigen Anschlußnabe an einer Seite des Schleiftellers und einer Schleiffläche an der anderen Seite des Schleiftellers und mit diamanthältigen Schleifsegmenten, die am Mantel des Tragkörpers angeordnet sind und zumindest an der von der Anschlußnabe abgewandten Seite den Trägerkörper überragen, wobei die Schleifsegmente in Umfangsrichtung des Schleiftellers breiter sind als in radialer Richtung.The invention relates to a grinding plate with a carrier body with a central connecting hub on one side of the grinding plate and a grinding surface on the other side of the grinding plate and with diamond-containing grinding segments which are arranged on the casing of the support body and at least on the side facing away from the connecting hub Extend the carrier body, the grinding segments being wider in the circumferential direction of the grinding plate than in the radial direction.

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 grinding plate with which grinding can be carried out in one operation both on the front and on the casing side. Another object of the invention is to improve such a grinding plate so that it can achieve higher stock removal rates compared to conventional grinding plates.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß anschließend an die Schleifsegmente ein Abriebring vorgesehen ist, der vorzugsweise von geschäumtem Kunststoff mit Füllstoffen gebildet wird.The object of the invention is achieved in that an abrasion ring is provided next to the grinding segments, which is preferably formed from foamed plastic with fillers.

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, daS 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 rate of a conventional grinding plate with roughly comparable roughness values when grinding at the front. 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.

Der erfindungsgemäße Schleifteller ist als Kombinationsfräser insbesondere bei Granit aller Verschleißklassen und bei Beton einsetzbar.The grinding plate according to the invention can be used as a combination milling cutter, in particular for granite of all wear classes and for concrete.

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.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnungen eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the accompanying drawings.

Die Fig. 1 und 2 zeigen jeweils ein Schaubild eines erfindungsgemäßen Schleiftellers, die Fig. 3 zeigt einen Schnitt durch einen erfindungsgemäßen Schleifteller und die Fig. 4 bis 11 zeigen schematisch verschiedene Einsatzmöglichkeiten des erfindungsgemäßen Schleiftellers.1 and 2 each show a diagram of a grinding plate according to the invention, FIG. 3 shows a section through a grinding plate according to the invention and FIGS. 4 to 11 schematically show different possible uses of the grinding plate according to the invention.

Der Schleifkörper ist mit S und das Werkstück mit W bezeichnet.The grinding wheel is marked with S and the workpiece with W.

Die drei wesentlichen Bauteile des erfindungsgemäßen Schleiftellers sind der Trägerkörper 1, die Schleifsegmente 2 und der Abriebring 3.The three essential components of the grinding plate according to the invention are the carrier body 1, the grinding segments 2 and the abrasion ring 3.

Der Trägerkörper 1 ist tellerförmig ausgeführt und die Schleifsegmente 2 sind an seinem Umfang angeordnet und zwar derart, daß sie den Trägerkörper beidseitig um ein Maß a1, a2 überragen. Dies ist beim Nutenschleifen von besonderer Bedeutung.The carrier body 1 is plate-shaped and the grinding segments 2 are arranged on its circumference in such a way that they protrude beyond the carrier body by a dimension a1, a2 on both sides. This is of particular importance for flute grinding.

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, daS die äußere Schneidkante K ständig scharf ist.The grinding segments 2 are designed to be relatively narrow, ie their length in the circumferential direction is substantially greater than the width in the radial direction of the grinding plate. When grinding at the end, the cutting ring formed by the cutting segments 2 is therefore relative narrow, which ensures that the outer cutting edge K is always sharp.

An die Schleifsegmente 2 schließt der Abriebring 3 an. 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 und den Rand 6 des Trägerkörpers 1 annähernd radial durchlaufen.The abrasion ring 3 adjoins the grinding segments 2. The grinding segments 2 are spaced from one another, so that sections 4 of the abrasion ring 3 protrude between the grinding segments 2. In the area of the sections 4 are the passage channels 5 for a coolant, which pass approximately radially through the wear ring and the edge 6 of the carrier body 1.

Innen ist der Abriebring 3 mit einer konischen Wandung 7 ausgeführt.The inside of the abrasion ring 3 is designed with a conical wall 7.

Der Abriebring 3 besteht aus geschäumtem Kunststoff, vorzugsweise Polyurethan mit Siliziumkarbid als Füllstoff.The wear ring 3 is made of foamed plastic, preferably polyurethane with silicon carbide as a filler.

Der Trägerkörper 1 ist mit einem mittigen Zulaufkanal 8 für die Kühlflüssigkeit versehen. Der Zulaufkanal 8 ist als Sackloch gebildet und endet in einem zylindrischen Ansatz 9 des Trägerkörpers 1. Der Ansatz 9 weist ein seitliches Austrittsloch 10 für die Kühlflüssigkeit auf, die dadurch radial auf den Abriebring 3 gespritzt wird. Um diesen Effekt zu verbessern, ist der Ansatz 9 mit einem Ablenkring 11 versehen, der dazu beiträgt, daß sich die Kühlflüssigkeit lange im Bereich des Werkzeuges befindet. Dieser Effekt wird durch den Innenkonus des Abriebringes 3 verstärkt.The carrier body 1 is provided with a central inlet channel 8 for the cooling liquid. The inlet channel 8 is formed as a blind hole and ends in a cylindrical shoulder 9 of the carrier body 1. The shoulder 9 has a lateral outlet hole 10 for the cooling liquid, which is thereby sprayed radially onto the abrasion ring 3. In order to improve this effect, the attachment 9 is provided with a deflection ring 11, which contributes to the coolant being in the area of the tool for a long time. This effect is reinforced by the inner cone of the wear ring 3.

Wie aus den Fig. 6, 7 und 11 ersichtlich, können mit dem erfindungsgemäßen Schleifteller horizontale und vertikale Flächen gleichzeitig geschliffen werden. Ebenso eignet sich der erfindungsgemäße Schleifteller zum Schleifen gekrümmter Kanten und zum Innenschleifen von Kurven (Fig. 8, 9).As can be seen from FIGS. 6, 7 and 11, horizontal and vertical surfaces can be ground simultaneously with the grinding plate according to the invention. 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 grinding segments 2, d. H. sections 4 provide damping during grinding, i.e. H. a chatter-free run is achieved.

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.

Mit dem erfindungsgemäßen Schleifteller werden die besten Leistungen erzielt, wenn er mit relativ hoher Geschwindigkeit, d. h. mit einer Umfangsgeschwindigkeit von 45 m/sek. eingesetzt wird. Dazu wird er auf einer Schleifmaschine montiert, die ca. 10.000 U/min. leistet und vorteilhaft eine zentrale Wasserzuführung durch die Spindel aufweist.The best performance is achieved with the grinding plate according to the invention if it is used at a relatively high speed, ie. H. with a peripheral speed of 45 m / sec. is used. For this purpose, it is mounted on a grinding machine that approx. 10,000 rpm. performs and advantageously has a central water supply through the spindle.

Die Fig. 4 zeigt schematisch eine Seitenansicht des Schleiftellers beim Einsatz im Flächenschliff. Die Fig. 5 zeigt die gleiche Ansicht beim Kantenschliff. Die Fig. 6 und 7 zeigen Seitenansichten des Schleiftellers beim Eckenschliff. Die Fig. 8 und 9 den Schleifteller in Draufsicht beim Kurvenschliff und die Fig. 10 und 11 zeigen eine Stirnansicht und eine Seitenansicht des Schleiftellers beim Nutenschliff.Fig. 4 shows schematically a side view of the grinding plate when used in surface grinding. 5 shows the same view for edge grinding. 6 and 7 show side views of the grinding plate for corner grinding. FIGS. 8 and 9 show the grinding plate in plan view when grinding curves and FIGS. 10 and 11 show an end view and a side view of the grinding plate when grooving.
