Description

Die Erfindung betrifft ein Schleifwerkzeug der im Oberbegriff des Anspruchs 1 angegebenen Art. Die Erfindung ist ferner auf eine Verwendung eines Schleifwerkzeugs gemäß Anspruch 10 gerichtet.The invention relates to a grinding tool specified in the preamble of claim 1. The invention is further directed to a use of a grinding tool according to claim 10.

Ein Schleifwerkzeug der nach Anspruch 1 gattungsgemäßen Art ist aus der US 3 181 281 bekannt.A grinding tool of the generic type according to claim 1 is known from US 3,181,281.

Zum Glätten von mineralischen Flächen, beispielsweise von Beton- oder Asphaltestrichen oder zum Schleifen von Kunst- oder Natursteinböden werden Schleif- und Poliermaschinen eingesetzt, die mit einem oder mehreren tellerförmigen, von einem kräftigen Antriebsmotor rotierend angetriebenen Schleifwerkzeug(en) mit zugehöriger Trägerplatte versehen sind. Die an der Trägerplatte mit Werkzeugtragelementen befestigten Bearbeitungswerkzeuge tragen bei der Rotation des Schleifwerkzeugs bzw. dessen Trägerplatte die oberste Schicht der zu behandelnden Fläche ab und ebnen diese in der gewünschten Weise ein bzw. sorgen für eine glatte, unter Umständen sogar polierte Oberfläche.For smoothing mineral surfaces, such as concrete or asphalt screeds or for grinding artificial or natural stone floors grinding and polishing machines are used, which are provided with one or more plate-shaped, driven by a powerful drive motor rotating grinding tool (s) with associated support plate. The attached to the support plate with tool support elements processing tools wear in the rotation of the grinding tool or its support plate from the top layer of the surface to be treated and pave them in the desired manner or provide a smooth, possibly even polished surface.

Die bei den bekannten Schleifwerkzeugen dieser Art bislang zum Einsatz kommenden Bearbeitungswerkzeuge bestehen aus Diamant oder Sinterwerkstoffen, die das zu bearbeitende Stein-, Asphalt-, Beton-, Epoxy- oder Kunststeinmaterial zerreiben, was beim Schleifvorgang eine verhältnismäßig große Staubentwicklung zur Folge hat. Aus diesem Grund müssen die eingesetzten Schleifmaschinen regelmäßig mit verhältnismäßig aufwendigen Absauganlagen sowie auch mit Wasseraufbereitungsanlagen für den Naßschliff ausgerüstet sein, die es erlauben den anfallenden Staub unmittelbar bei seinem Anfall zu binden und abzuführen.The previously used in the known abrasive tools of this type processing tools consist of diamond or sintered materials that grind the stone, asphalt, concrete, epoxy or artificial stone material to be machined, what During grinding, a relatively large amount of dust has the consequence. For this reason, the grinders used must be regularly equipped with relatively expensive extraction systems as well as with water treatment plants for wet grinding, which allow it to bind the accumulating dust immediately in his attack and dissipate.

Als besonders nachteilig hat sich bei den bekannten, zum Einsatz kommenden Bearbeitungswerkzeugen deren bei manchen der zu bearbeitenden Flächenmaterialien die verhältnismäßig geringe Standzeit erwiesen, nach der die Werkzeuge bereits ausgetauscht werden müssen. Je nach Art der zu schleifenden Fläche sind auch die erreichbaren Schnittleistungen verhältnismäßig gering. Insbesondere bei großen, zu bearbeitenden Flächen werden die gesamten Bearbeitungszeiten mit den bekannten, zum Einsatz kommenden Werkzeugen sehr lang und damit für Bauherren entsprechend teuer.Particularly disadvantageous in the known, used for use machining tools whose some of the surface materials to be machined has proven the relatively short life, after which the tools must already be replaced. Depending on the type of surface to be ground and the achievable cutting performance are relatively low. Especially with large surfaces to be machined, the entire processing times with the known tools used for the very long and therefore correspondingly expensive for builders.

Aufgabe der Erfindung ist es, ein Schleifwerkzeug der eingangs genannten Art zur Verfügung zu stellen, mit dem bei der Bearbeitung von insbesondere mineralischen Flächen wie beispielsweise Steinfußböden oder Betonestrichen, aber auch bei demgegenüber vergleichsweise "weichen" Oberflächen wie Gußasphalt, Asphalt oder kunstharzgebundenen Terrazzoböden, Spachtelmasse, Klebstoffresten, Epoxy usw. neben einer hohen Genauigkeit auch eine höhere Schnittleistung und bessere Standzeit der Werkzeuge erreicht wird. Darüber hinaus soll mit der Erfindung möglichst auch die bei der Bearbeitung auftretende Staubentwicklung verringert werden.The object of the invention is to provide a grinding tool of the type mentioned, with which in the processing of particular mineral surfaces such as stone floors or concrete screeds, but also in contrast comparatively "soft" surfaces such as cast asphalt, asphalt or resin-bonded terrazzo floors, filler , Adhesive residues, epoxy, etc. in addition to a high accuracy and a higher cutting performance and better tool life is achieved. In addition to be reduced as possible with the invention occurring during processing dust.

Diese Aufgabe wird mit der Erfindung durch ein Schleifwerkzeug gemäß Anspruch 1 und eine Verwendung eines Schleifwerkzeugs gemäß Anspruch 10 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved with the invention by a grinding tool according to claim 1 and a use of a grinding tool according to claim 10. Advantageous embodiments are specified in the subclaims.

Die aus polykristallinem Diamant bestehenden Elemente bzw. die diese bildenden, mit polykristallinem Diamant beschichteten Hartmetallplatten weisen eine gegenüber den bekannten Bearbeitungswerkzeugen erheblich verbesserte Standzeit auf, die um einen Faktor 10 höher liegen kann als die von reinen Diamantwerkzeugen oder gesinterten Schleifwerkzeugen. Es wird angenommen, daß diese längere Standzeit auf die Kombination einer extrem harten, im wesentlichen von dem polykristallinen Diamant gebildeten Oberfläche der erfindungsgemäß zum Einsatz kommenden Werkzeuge und deren demgegenüber vergleichsweise zähen Kern aus Hartmetall bzw. der Matrix aus Kobalt oder anderem Sintermetall zurückzuführen ist, worin die PKD-Teile eingebettet sind. Diese besonders vorteilhafte Paarung bewirkt offenbar auch, daß das zu bearbeitende Material während des Schleifvorgangs nicht oder jedenfalls nicht nennenswert zerrieben wird, sondern es tatsächlich zu einer Zerspanung kommt, die im allgemeinen mit nur geringer Staubentwicklung einhergeht.The consisting of polycrystalline diamond elements or these forming, coated with polycrystalline diamond hard metal plates have a comparison with the known processing tools significantly improved life, which may be higher by a factor of 10 than that of pure diamond tools or sintered grinding tools. It is believed that this longer service life is due to the combination of an extremely hard surface formed substantially by the polycrystalline diamond of the tools used in the present invention and their comparatively tough hard metal core or cobalt or other sintered metal matrix the PKD parts are embedded. This particularly advantageous pairing apparently also causes the material to be processed during the grinding process is not or at least not significantly rubbed, but it actually comes to a chipping, which is generally associated with little dust.

Die PKD-Elemente sind unter einem Spanwinkel von 40 bis 85° zur Trägerplatte angeordnet, um den Zerspanungsvorgang weiter zu begünstigen. Um in ein und demselben Arbeitsgang eine besonders saubere Oberfläche der bearbeiteten Fläche zu erhalten, ist zusätzlich zu den PKD-Elementen am Werkzeugtragelement mindestens ein Diamantschleifelement angeordnet.The PCD elements are arranged at a rake angle of 40 to 85 ° to the carrier plate in order to further promote the cutting process. In order to obtain a particularly clean surface of the machined surface in one and the same operation, at least one diamond grinding element is arranged in addition to the PCD elements on the tool support element.

Die PKD-Elemente sind vorzugsweise unter einem Winkel von 10-55° relativ zur Umfangsrichtung der Trägerplatte angeordnet, wobei hier die Winkelstellung an die Art des zu bearbeitenden Werkstoffes angepaßt werden kann, um die Zerspanungsleistung und ggf. auch die Spanform zu optimieren. Das Werkzeugtragelement kann in seiner Winkelstellung relativ zur Trägerplatte einstellbar an dieser angeordnet sein; gleichsam ist es auch möglich, die am Werkzeugtragelement angeordneten, die PKD-Bearbeitungswerkzeugelemente aufnehmenden Aufnahmetaschen in ihrer Lage relativ zum Tragelement einstellbar auszugestalten.The PCD elements are preferably arranged at an angle of 10-55 ° relative to the circumferential direction of the support plate, in which case the angular position can be adapted to the type of material to be machined in order to optimize the cutting performance and possibly also the chip shape. The tool support member may be arranged in its angular position relative to the support plate adjustable at this; it is as it is possible, the arranged on the tool support member, the PCD machining tool elements receiving pockets in their position relative to the support element designed to be adjustable.

Die PKD-Elemente können eine kreis-, halbkreis- oder mehreckförmige Grundform haben. Insbesondere sind hier trapezförmige, quadratische, rechteckige, dreieckige oder sonstwie polygonale Formen denkbar, die unterschiedliche Zerspanungsverhalten haben können und somit auch gezielt für dem zu bearbeitenden Boden o.dgl. ausgewählt werden können, um die gewünschte Oberflächengüte zu erhalten.The PCD elements can have a circular, semicircular or polygonal basic shape. In particular, here trapezoidal, square, rectangular, triangular or otherwise polygonal shapes are conceivable that can have different cutting behavior and thus also specifically for the soil to be processed or the like. can be selected to obtain the desired surface finish.

Die PKD-Elemente sind in ihren Aufnahmetaschen vorzugsweise mittels einer Hartlotverbindung befestigt, womit ein sehr sicherer Sitz gewährleistet und wirksam verhindert wird, daß die PKD-Platten sich in ihren Aufnahmetaschen lösen und aus diesen herausfallen können. Es ist aber auch denkbar, die PKD-Elemente mit Schraubverbindungen in ihren Aufnahmetaschen zu arretierenThe PCD elements are preferably fixed in their receiving pockets by means of a braze joint, which ensures a very secure fit and effectively prevents the PCD plates can be solved in their receiving pockets and fall out of these. But it is also conceivable to lock the PCD elements with screw in their receiving pockets

Es ist möglich, mehrere PKD-Elemente verschiedener geometrischer Grundform am selben Werkzeugtragelement anzuordnen, so daß unterschiedliche Zerspanungsverhalten beim selben Schleifdurchgang an der Oberfläche der bearbeiteten Fläche zur Anwendung kommen. Ebenso ist es auch möglich, PKD-Elemente verschiedener geometrischer Grundform an verschiedenen, an der Trägerplatte vorgesehenen Werkzeugtragelementen anzuordnen.It is possible to arrange a plurality of PCD elements of different geometric basic shape on the same tool support element, so that different cutting behavior in the same grinding pass on the surface of the machined surface are used. Likewise, it is also possible to arrange PCD elements of different geometrical basic shape on different, provided on the support plate tool support elements.

Das in der Zeichnung dargestellt, in seiner Gesamtheit mit 10 bezeichnete Schleifwerkzeug ist Bestandteil einer in der Zeichnung nicht näher dargestellten Bodenschleifmaschine, die zum Abschleifen von Estrichen, Steinfußböden, Asphaltflächen oder dergleichen bzw. zum Entfernen von Klebstoffresten, Spachtelmasse oder Epoxy von solchen Flächen eingesetzt werden kann.The illustrated in the drawing, designated in its entirety by 10 grinding tool is part of a bottom grinding not shown in the drawing, which are used for grinding screeds, stone floors, asphalt surfaces or the like or for removing adhesive residues, putty or epoxy of such surfaces can.

Das Schleifwerkzeug 10 besteht im wesentlichen aus einer Trägerplatte 11, die mit einer zentrischen Ausnehmung 12 versehen ist, mit der sie fest an der (nicht dargestellten) Antriebswelle der Schleifmaschine angeschlossen ist. An der Unterseite 13 der Trägerplatte 11 ist diese mit drei oder mehreren gleichmäßig über den Umfang verteilt angeordneten Werkzeugtragelementen 14 versehen, die mittels Befestigungsschrauben fest, aber lösbar an der Trägerplatte 11 angeschlossen sind. Diese Segmente können auch direkt (löten, schrauben, kleben oder ansintern) auf die Trägerplatte aufgebracht werden.The grinding tool 10 consists essentially of a support plate 11 which is provided with a central recess 12, with which it is firmly connected to the (not shown) drive shaft of the grinding machine. On the underside 13 of the support plate 11, this is provided with three or more uniformly distributed over the circumference arranged tool support members 14 which are fixed by means of fastening screws, but releasably connected to the support plate 11. These segments can also be applied directly (soldering, screwing, gluing or sintering) to the carrier plate.

Die Werkzeugtragelemente 14 wiederum weisen an ihrer Unterseite 15 je ein Diamantschleifelement 16 in Form eines angesinterten, etwa quaderförmigen Blockes sowie eine Aufnahmeleiste 17 mit mehreren Aufnahmetaschen 18 auf, in denen Bearbeitungswerkzeuge 19 formschlüssig aufgenommen und durch eine Hartlotverbindung fest mit der sie umgebenden Aufnahmeleiste verbunden sind. Dabei ist die Anordnung so getroffen, daß die Bearbeitungswerkzeuge 19 (PKD) mit ihren aus eigentlichen Schneidkanten 20 aus den Aufnahmetaschen herausragen.The tool support elements 14 in turn each have on their underside 15 a diamond grinding element 16 in the form of a sintered, approximately cuboid block and a receiving strip 17 with a plurality of receiving pockets 18, in which processing tools 19 positively received and connected by a braze joint firmly with the surrounding receiving bar. The arrangement is such that the processing tools 19 (PCD) protrude with their actual cutting edges 20 from the receiving pockets.

Die Bearbeitungswerkzeuge 19 bestehen bei einer bevorzugten Ausführungsform aus Hartmetallelementen 21, die an ihrer Oberfläche zumindest im Bereich der Schneidkanten mit einer Schicht 22 aus polykristallinem Diamant (PKD) versehen sind, die an die Hartmetalloberfläche in geeigneter Weise angesintert ist. Alternativ können in einer anderen bevorzugten Ausführungsform die Bearbeitungswerkzeuge auch durchgängig aus polykristallinem Diamant bestehen, d.h. aus PKD-Splittern oder anderen geometrischen PKD-Teilen, die in eine geeignete Matrix aus Kobalt oder einem anderen Sintermetall eingebunden sind, wie dies an sich bekannt ist. Die Hartmetall- bzw. PKD-Elemente 21 können verschiedene geometrische Formen aufweisen, beispielsweise wie in Fig.2 erkennbar rund, trapezförmig und/oder dreieckig ausgestaltet sein. Als vorteilhaft hat sich hier auch eine sechseckige Form erwiesen, die aus den geometrischen Grundformen eines Rechtecks bzw. Quadrats und eines Trapezes zusammengesetzt ist und die auch als sargförmig bezeichnet werden kann.The machining tools 19 in a preferred embodiment consist of hard metal elements 21, which are provided on their surface at least in the region of the cutting edges with a layer 22 of polycrystalline diamond (PCD), which is sintered to the hard metal surface in a suitable manner. Alternatively, in another preferred embodiment, the processing tools may also consist of polycrystalline diamond throughout, i. PCD chips or other PCD geometric parts incorporated into a suitable matrix of cobalt or other sintered metal, as is well known in the art. The hard metal or PCD elements 21 may have different geometric shapes, for example, as shown in Figure 2 recognizable round, trapezoidal and / or triangular designed. It has proved to be advantageous here also a hexagonal shape, which is composed of the geometric basic shapes of a rectangle or square and a trapezoid and which can also be referred to as coffin-shaped.

Die Aufnahmeleiste ist bei an der Trägerplatte montierten Werkzeugtragelement bei dem in Fig.2 und 3 illustrierten Ausführungsbeispiel so angeordnet, daß sie sich in unmittelbarer Nähe des äußeren Randes der Trägerplatte 11 befindet. Die in ihr angeordneten Aufnahmetaschen oder -nuten 18 sind unter einem Winkel γ zur Umfangs- oder Tangentialrichtung t der Trägerplatte 11 angeordnet, der bei dem ersten Ausführungsbeispiel ca. 15° beträgt. Daneben sind die Aufnahmetaschen auch schräg zur Trägerplatte geneigt angeordnet unter einem Winkel α, der zwischen 40 und 85° betragen kann und der bei dem gezeigten Beispiel eine Größe von etwa 80° hat.The receiving strip is arranged in mounted on the support plate tool support member in the illustrated in Figures 2 and 3 embodiment so that it is in the immediate vicinity of the outer edge of the support plate 11. The arranged in her receiving pockets or grooves 18 are arranged at an angle γ to the circumferential or tangential direction t of the support plate 11, which is approximately 15 ° in the first embodiment. In addition, the receiving pockets are also inclined to the support plate inclined at an angle α, the may be between 40 and 85 ° and in the example shown has a size of about 80 °.

Bei der zweiten, in Fig.4 gezeigten Ausführungsform hat die Aufnahmeleiste 17 eine nahezu radiale Ausrichtung, d.h. sie weist etwa in Richtung des Mittelpunktes der Trägerplatte 11. Die Aufnahmetaschen 18 schließen bei dieser Ausführungsform mit der Tangentialrichtung t der Trägerplatte einen Winkel γ ein, der erheblich größer ist als bei der ersten Ausführungsform und der ca. 80° beträgt.In the second embodiment, shown in Figure 4, the receiving strip 17 has a nearly radial orientation, ie, it points approximately in the direction of the center of the support plate 11. The receiving pockets 18 include in this embodiment with the tangential direction t of the support plate an angle γ, the is considerably larger than in the first embodiment and is about 80 °.

Die erfindungsgemäß als Bearbeitungswerkzeuge zum Einsatz kommenden Hartmetallelemente mit PKD-Beschichtung bzw. die PKD-Vollelemente haben gegenüber den bislang für derartige Schleifmaschinen eingesetzten Werkzeugen eine deutlich höhere Schnittleistung und einer erheblich längere Standzeit, die je nach Art des zu bearbeitenden Bodens leicht um einen Faktor 10 über den Lebenserwartungen bekannter, zu diesem Zweck bisher eingesetzter Werkzeuge liegen kann. Man nimmt an, daß die längere Standzeit und die bessere Schnittleistung darauf zurückzuführen ist, daß die in ihrem Kern bzw. ihrer Matrix vergleichsweise zähen Bearbeitungswerkzeuge nach der Erfindung den zu bearbeitenden Beton, Asphalt, Natur- oder Kunststein bzw. darauf befindliche Klebstoffreste oder Epoxy mit ihren extrem harten PKD-Bestandteilen nicht wie die bisher eingesetzten Werkzeuge zerreiben, sondern spanend abtragen, was auch den angenehmen Effekt hat, daß die Staubentwicklung beim Arbeiten mit den erfindungsgemäßen Werkzeugen erheblich geringer ist als mit den bislang eingesetzten Schleifwerkzeugen.The carbide elements according to the invention used as machining tools with PCD coating or the PCD full elements have compared to the tools previously used for such grinders a significantly higher cutting performance and a significantly longer life, depending on the type of soil to be processed easily by a factor of 10 can be above the life expectancy known tools previously used for this purpose. It is believed that the longer life and better cutting performance is due to the fact that in their core or matrix comparatively tough processing tools according to the invention the concrete to be processed asphalt, natural or artificial stone or adhesive residues or epoxy located thereon Their extremely hard PCD components do not grind like the tools used hitherto, but remove them by machining, which also has the pleasant effect that dust generation when working with the tools according to the invention is considerably lower than with the grinding tools used hitherto.

Die Erfindung ist nicht auf das beschriebene und dargestellte Ausführungsbeispiel beschränkt, sondern es sind verschiedene Änderungen und Ergänzungen denkbar, ohne den Rahmen der Erfindung zu verlassen. Die Bearbeitungswerkzeuge können beispielsweise auch andere geometrische Formen haben, beispielsweise quadratisch, rechteckig oder elliptisch sein. Werkzeuge gleicher geometrische Grundform können, ggf. auch in verschiedenen Größenabstufungen, an ein- und derselben Werkzeugtragplatte angeordnet sein, und zwar falls gewünscht auch in mehr als lediglich einer Aufnahmeleiste.The invention is not limited to the described and illustrated embodiment, but various changes and additions are conceivable without departing from the scope of the invention. For example, the machining tools may also have other geometric shapes square, rectangular or elliptical. Tools of the same geometric basic shape can, if appropriate, also be arranged in different size graduations, on one and the same tool carrying plate, specifically if desired in more than one receiving bar.
