Die Erfindung betrifft eine Bearbeitungsvorrichtung, insbesondere eine Schleif- oder Fräsvorrichtung, vorzugsweise zum Planieren von Steinen, mit einem rotierenden Werkzeug, das ein Drehzentrum aufweist sowie mindestens ein Schneidelement, das an einem vom Drehzentrum entfernten Ort angeordnet ist, wobei das rotierende Werkzeug mittels einer Spindel gelagert und drehangetrieben ist. Des weiteren betrifft die Erfindung ein Verfahren zum Betreiben der Bearbeitungsvorrichtung.The invention relates to a processing device, in particular a Grinding or milling device, preferably for leveling stones, with a rotating tool that has a turning center as well at least one cutting element located at a distance from the center of rotation Location is arranged, wherein the rotating tool by means of a Spindle stored and rotationally driven. Furthermore, the concerns Invention a method for operating the processing device.
Bei der Herstellung und Bearbeitung von Steinen und Kunststeinen, insbesondere von Ziegelsteinen oder Steinrohlingen oder ähnlichen keramischen Werkstücken, stellt sich unter anderem die Aufgabe, derartige Steine an parallelen Flächen zu schleifen bzw. zu fräsen, um sie auf das benötigte bzw. gewünschte Maß zu bringen.In the production and processing of stones and artificial stones, in particular bricks or stone blanks or the like ceramic workpieces, arises, inter alia, the task of such Grind or cut stones on parallel surfaces to open them to bring the required or desired level.
In der EP 0 785 839 B1 ist ein Verfahren und eine zugehörige Vorrichtung
zum seitlichen Planieren solcher Steine offenbart. Zur Bearbeitung
des Steins kommt ein rotierendes Fräs- bzw. Schleifwerkzeug zum
Einsatz, das eine rotierende Scheibe aufweist, deren Umfang mit
Schneidelementen besetzt ist. Bei diesen Schneidelementen kann es sich
um solche mit geometrisch bestimmter Schneide handeln (Fräswerkzeug)
bzw. um eines mit geometrisch unbestimmter Schneide (Schleifwerkzeug).
Eine Vorrichtung zum beidseitigen Beschleifen eines Steins ist auch aus der DE 296 13 831 U1 bekannt. Auch bei dieser Lösung kommen die genannten rotierenden Schleifwerkzeuge zum Einsatz.A device for two-sided grinding of a stone is also known from DE 296 13 831 U1 . Also in this solution, the aforementioned rotating grinding tools are used.
Beim Maßschleifen eines Steins mittels der genannten Bearbeitungsvorrichtung stellt der dabei entstehende Staub ein erhebliches Problem dar. Er verunreinigt die Bearbeitungsvorrichtung und kann über die Dichtungen bis in die Lager der Spindel vordringen und diese durch sein abrasives Verhalten zerstören. Generell erhöht der die gesamte Bearbeitungsvorrichtung verunreinigende Staub den Verschleiß der das Werkzeug antreibenden Teile. Damit nimmt die Standzeit der Bearbeitungsvorrichtung ab. Ferner hat es sich als problematisch herausgestellt, dass der Bearbeitungsvorgang eine erhebliche Hitzeentwicklung verursacht, so dass das Werkzeug und die Bearbeitung selber einer hohen thermischen Belastung ausgesetzt sind. All dies führt im Ergebnis zur Herabsetzung der maximalen Schleifgeschwindigkeit und zur Verringerung der Schliffqualität.When custom grinding a stone by means of said processing device represents the resulting dust is a significant problem. It contaminates the processing device and can over the seals penetrate into the bearing of the spindle and this by its abrasive Destroy behavior. Generally, this increases the overall processing device Dirty dust the wear of the tool driving parts. This increases the service life of the processing device from. Furthermore, it has turned out to be problematic that the Machining process causes a significant heat, so that the tool and the machining itself a high thermal Are exposed to stress. All this leads to the result of the reduction the maximum grinding speed and to reduce the grinding quality.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Bearbeitungsvorrichtung der gattungsgemäßen Art derart weiterzubilden, dass die Belastung der Vorrichtung mit abrasiven Staubpartikeln vermindert wird. Damit soll die Standzeit der Vorrichtung erhöht werden. Ferner soll die Vorrichtung so weiterentwickelt werden, dass die Wärmeentwicklung im Betrieb reduziert wird. Weiterhin soll ein Verfahren zum Betreiben der Bearbeitungsvorrichtung vorgeschlagen werden, mit dem diese Zielsetzung unterstützt und erreicht werden kann. The invention is therefore based on the object , a processing device of the generic type such that the load on the device is reduced with abrasive dust particles. This is intended to increase the service life of the device. Furthermore, the device should be developed so that the heat generation is reduced during operation. Furthermore, a method for operating the processing device is proposed, with which this objective can be supported and achieved.
Die Lösung dieser Aufgabe durch die Erfindung ist vorrichtungsgemäß dadurch gekennzeichnet, dass die Bearbeitungsvorrichtung Mittel aufweist, mit denen ein Fluid, insbesondere Luft, zum Drehzentrum des Werkzeugs geleitet werden kann, und dass das Werkzeug weiterhin mindestens einen Fluidkanal aufweist, der das Drehzentrum des Werkzeugs mit dem mindestens einen Schneidelement fluidisch verbindet.The solution of this object by the invention is according to the device characterized in that the processing device comprises means by which a fluid, in particular air, can be passed to the center of rotation of the tool, and that the tool further comprises at least one fluid channel, which with the center of rotation of the tool the fluidically connects at least one cutting element.

Damit wird nicht nur die Bearbeitungsvorrichtung vor der Staubeinwirkung geschützt, es wird auch möglich, die Betriebstemperatur signifikant herabzusetzen, da der durch das Werkzeug geleitete Luftstrahl dieses kühlt.Accordingly, it is therefore provided that the processing device so is executed that it becomes possible, one from the center of the machining tool Outgoing air flow to the edge of the tool to lead to the cutting elements and thereby on the one hand the resulting Dust transported to the outside and on the other a cooling cause the tool engagement surfaces. This will not only the Machining device protected from the action of dust, it is also possible to reduce the operating temperature significantly, as the air jet guided by the tool cools this.
Gemäß einer ersten Weiterbildung ist vorgesehen, dass das Mittel zum Zuleiten von Fluid, also insbesondere von Luft, zum Drehzentrum des Werkzeugs als Hohlwelle ausgebildet ist, die als Spindel des Werkzeugs dient. Die Hohlwelle kann dabei koaxial in einem im Wesentlichen zylinderförmig ausgebildeten Antriebsmotor gelagert sein.According to a first development, it is provided that the means for Supplying fluid, so in particular of air, to the center of rotation of the Tool is designed as a hollow shaft, which serves as a spindle of the tool serves. The hollow shaft can be coaxial in a substantially be stored cylinder-shaped drive motor.
Eine konstruktiv besonders einfache Ausgestaltung der erfindungsgemäßen Bearbeitungsvorrichtung wird erreicht, wenn das Werkzeug einen Grundkörper sowie einen Abdeckkörper aufweist, zwischen denen der mindestens eine Fluidkanal ausgebildet ist. Dabei können sowohl der Grundkörper als auch der Abdeckkörper im Wesentlichen rotationssymmetrisch ausgebildet sein. Weiterhin hat es sich als vorteilhaft erwiesen, dass die Breite des Fluidkanals mit steigendem radialen Abstand vom Drehzentrum abnimmt; hierbei ist insbesondere an eine lineare Abnahme - zumindest über einen Abschnitt - gedacht.A structurally particularly simple embodiment of the invention Machining device is reached when the tool a Base body and a cover body, between which the at least one fluid channel is formed. It can both the Main body and the cover body substantially rotationally symmetrical be educated. Furthermore, it has proved to be advantageous that the width of the fluid channel with increasing radial distance from Turning center decreases; this is in particular a linear decrease - at least over a section - thought.
Der Grundkörper kann an seiner dem Fluidkanal zugewandten Seite, zumindest über einen Abschnitt hinweg, kegelförmig ausgeformt sein. Entsprechend kann der Abdeckkörper an seiner dem Fluidkanal zugewandten Seite eben ausgeformt werden.The base body can, on its side facing the fluid channel, be conically shaped at least over a section. Accordingly, the cover body facing at its the fluid channel Side just be formed.
Die Bewerkstelligung der Luftströmung über das Drehzentrum des Werkzeugs und den Fluidkanal bis zu den Schneidelementen des Werkzeugs kann sowohl aktiv als auch passiv erfolgen. Hierunter ist zu verstehen, dass im einen Falle, also beim aktiven Erzeugen der Luftströmung, das Mittel, mit dem das Fluid zum Drehzentrum des Werkzeugs geleitet werden kann, mit einem Gebläse, einem Kompressor, einer Pumpe oder ähnlichem in Verbindung steht. Falls erforderlich kann an der Vorrichtung selbstverständlich auch eine aktive und passive Erzeugen der Luftströmung vorgesehen seinThe achievement of the air flow over the center of rotation of the Tool and the fluid channel to the cutting elements of the tool can be both active and passive. Below is too understand that in one case, ie when actively generating the air flow, the means by which the fluid to the center of rotation of the tool can be directed with a blower, a compressor, a Pump or the like in connection. If necessary can Of course, the device also active and passive generating be provided the air flow
Im anderen Falle, also bei passiver Erzeugung der Luftströmung, sind Elemente (Luftfördereinrichtungen) in der Bearbeitungsvorrichtung vorgesehen, die selber die Luftströmung ohne ein Gebläse oder Ähnliches erzeugen. Mit Vorteil ist hierzu vorgesehen, dass der Grundkörper und/oder der Abdeckkörper mindestens eine Leitfläche aufweist, entlang derer das Fluid, insbesondere Luft, vom Drehzentrum des Werkzeugs zu dem mindestens einen Schneidelement geleitet werden kann; dabei weist insbesondere der Abdeckkörper diese Leitfläche auf. Die Leitfläche kann zwischen dem Drehzentrum des Werkzeugs und dem Schneidelement gerade oder bogenförmig verlaufen, wobei insbesondere eine spiralförmige Ausbildung vorgesehen ist. Hiernach ist die Leitfläche also nach Art einer Turbinenschaufel ausgeformt, so dass bei Rotation des Werkzeugs eine Förderwirkung für die Luft entsteht. In the other case, ie with passive generation of the air flow, are Elements (air conveyors) in the processing device provided itself the air flow without a fan or the like produce. Advantageously, it is provided that the basic body and / or the cover body has at least one guide surface, along derer the fluid, in particular air, from the center of rotation of the tool to the at least one cutting element can be passed; points in particular the covering body on this guide surface. The baffle can between the center of rotation of the tool and the cutting element straight or curved, in particular a spiral Training is provided. After that, the guide surface is after Formed like a turbine blade, so that upon rotation of the tool a conveying effect for the air is created.
Das Verfahren zum Betreiben der Bearbeitungsvorrichtung, vorzugsweise zum Planieren von Steinen, setzt das mit mindestens einem Schneidelement versehene rotierende Werkzeug ein, das auf einer Spindel gelagert und drehangetrieben ist. Verfahrensgemäß ist vorgesehen, dass über ein Mittel ein Gas zum Drehzentrum des Werkzeugs und von dort über einen Fluidkanal zu dem mindestens einen Schneidelement geleitet wird, wobei dem Gas, vorzugsweise vor dessen Eintritt in die Mittel, Flüssigkeit zugegeben wird. Das Gas ist bevorzugt Luft, die Flüssigkeit ist bevorzugt Wasser. Dabei hat es sich als vorteilhaft erwiesen, wenn die Flüssigkeit dem Gas fein verteilt, insbesondere in Form von Tröpfchen, zugegeben wird.The method for operating the processing device, preferably for leveling stones, that sets with at least one cutting element provided rotating tool mounted on a spindle and is rotationally driven. According to the method is provided that over a Means a gas to the center of rotation of the tool and from there via a Fluid channel is passed to the at least one cutting element, wherein the gas, preferably before it enters the medium, liquid is added. The gas is preferably air, the liquid is preferred Water. It has proved to be advantageous if the liquid dispersed in the gas, especially in the form of droplets, is added.
Mit der verfahrensgemäßen Vorgehensweise wird erreicht, dass sowohl der Staubableiteffekt als auch der Kühleffekt erhöht werden kann. Die das Werkzeug durchströmende Luft wird also mit Wasser versehen, so dass sich ein feiner Nebel bildet, dessen Reinigungs- und Kühlwirkung wesentlich höher ist als diejenige von reiner Luft.With the procedural approach is achieved that both the Staubableiteffekt and the cooling effect can be increased. The the air flowing through the tool is thus provided with water, so that forms a fine mist, its cleaning and cooling effect is much higher than that of pure air.

In Fig. 1 ist ein Ziegelstein 15 dargestellt, der vor seiner Verwendung an
den Endseiten plan geschliffen werden muss. Hierzu wird er in Richtung
des Pfeils durch eine Bearbeitungsvorrichtung gefördert, die in der Figur
nur sehr schematisch dargestellt ist. Gezeigt sind vier Schleifscheiben,
von denen jeweils zwei in Förderrichtung hintereinander angeordnet
sind, wobei diese beidseits der Planflächen des Ziegelsteins 15 positioniert
sind. Beim Vorbeilaufen des Ziegelsteins 15 an den Werkzeugen 2
wird er auf das benötigte bzw. gewünschte Maß geschliffen.In Fig. 1 , a
In Fig. 2 ist eine Bearbeitungsvorrichtung 1 dargestellt, die diesem
Zweck dient. Gemäß der Konstellation nach Fig. 1 werden also vier
Bearbeitungsvorrichtungen 1 gemäß Fig. 2 dort eingesetzt. Die Bearbeitungsvorrichtung
1 weist ein Werkzeug 2 auf, das als Schleifscheibe
ausgebildet ist. Das Werkzeug 2 rotiert um ein Drehzentrum 3; mit
Abstand von diesem Drehzentrum 3 sind eine Anzahl Schneidelemente 4
- hier in Form eines Schleifbesatzes - am Umfang des Werkzeugs 2
angeordnet. Das Werkzeug 2 ist über eine Spindel 5 drehbar gelagert,
wobei die Spindel 5 von einem Antriebsmotor 8 angetrieben wird.In Fig. 2 , a processing device 1 is shown, which serves this purpose. According to the constellation according to FIG. 1 , therefore, four processing devices 1 according to FIG. 2 are used there. The processing device 1 has a
Wie Fig. 2 entnommen werden kann, ist die Spindel dabei als Hohlwelle
ausgeführt, so dass der innere Bereich der Hohlwelle als Mittel 6 zum
Zuleiten von Luft fungiert. Im vorliegenden Falle wird die Luft mit
einem Gebläse 14 in die Hohlwelle gefördert. An dem werkzeugseitigen
Ende der Hohlwelle 6 wird die Luft in radialer Richtung umgelenkt und
über den Fluidkanal 7 bis zu den Schneidelementen 4 gefördert.As can be seen from Fig. 2 , the spindle is designed as a hollow shaft, so that the inner portion of the hollow shaft acts as
Zur Ausbildung der Luftpassage von der Hohlwelle 6 über den Bereich
des Drehzentrums 3 des Werkzeugs 2 und den Fluidkanal 7 bis zum
Schneidelement 4 ist das Werkzeug wie folgt aufgebaut: Es weist einen
Grundkörper 9 auf, der im Wesentlichen rotationssymmetrisch ausgebildet
ist, wie es in Fig. 3a gesehen werden kann. An der von der Hohlwelle
6 abgewandten Seite 11 ist der Grundkörper 9 kegelförmig ausgebildet.
Diese Seite 11 des Grundkörpers 9 wird von einem Abdeckkörper 10
abgedeckt, der in den Fig. 4a und 4b zu sehen ist. Wie es am besten in
Fig. 2 gesehen werden kann, bildet sich damit zwischen der Seite 11 des
Grundkörpers 9 und der Seite 12 des Abdeckkörpers 10 der Fluidkanal 7
aus, dessen Breite B mit zunehmendem Radius geringer wird. Der Abdeckkörper
10 weist im Bereich des Drehzentrums 3 einen strömungstechnisch
günstig ausgebildeten Umlenkabschnitt 16 auf (s. Fig. 4b), der
die in Achsrichtung durch die Hohlwelle 6 auf den Umlenkabschnitt 16
auftreffende Luft in die radiale Richtung umlenkt und in den Fluidkanal
7 fördert.To form the air passage from the
Wie bereits erwähnt - siehe hierzu Fig. 2 -, kann die Luft durch ein
Gebläse 14 in die Hohlwelle 6 gefördert werden. Es ist jedoch nicht
unbedingt notwendig, dass eine insofern aktive Versorgung mit Luft
erfolgt. In Fig. 4 ist vielmehr zu sehen, dass Luftfördereinrichtungen in
Form von Leitflächen 13 auf dem Abdeckkörper 10 angeordnet sein
können, die zur Folge haben, dass bei Rotation des Werkzeugs (siehe
Pfeil der Drehrichtung in Fig. 4a) Luft über die Hohlwelle 6 angesaugt
und durch den Fluidkanal 7 in Richtung Schneidelement 4 gefördert
wird. Wie in Fig. 4a zu erkennen ist, sind die Leitflächen 13 turbinenschaufelähnlich
ausgeformt, wodurch der Fördereffekt bewerkstelligt
wird.As already mentioned - see FIG. 2 -, the air can be conveyed through a
Wie in Fig. 3b gesehen werden kann, ist im Ausführungsbeispiel vorgesehen,
dass die Schneidelemente 4 als auswechselbare Einsätze an den
Grundkörper 9 angeschraubt werden. Hierfür weist der Grundkörper 9 -
siehe hierzu Fig. 3a - acht Bohrungen gleichmäßig über den Umfang
verteilt auf, an die die Werkzeugträger mit den Schneidelementen 4
angeschraubt werden können. As can be seen in FIG. 3b , it is provided in the exemplary embodiment that the

zwischen Gebläse 14 und Antriebsmotor 8, eine Vorrichtung integriert
sein kann, mit der Wasser in Tröpfchenform in den Luftstrahl eingebracht
werden kann. Damit kann erreicht werden, dass sich die Wärmekapazität
des Fluidstrahls erhöht, so dass die Fähigkeit zum Abtransport
von Wärme am Ort des Schneidelements 4 verbessert wird. In gleicher
Weise kann dadurch Staub gebunden und abgeführt werden.In Fig. 2 is not shown that in the air flow path, z. B. between
