- a device and associated Betreibungsvon are from the document DE 72114226 U known.
- a rotating milling or grinding tool is used to process the stone Insert having a rotating disc whose circumference is occupied by cutting elements.
- These cutting elements may be those with a geometrically determined cutting edge (milling tool) or one with a geometrically indefinite cutting edge (grinding tool).
- a device for two-sided grinding a stone is also from the DE 296 13 831 U1 known. Also in this solution, the aforementioned rotating grinding tools are used.

- the coolant channels for coolant flow from the inside to the outside or outside to inside has.
- the segment disc is mounted on a hollow shaft designed as a coolant supply line, through which the coolant can pass into the coolant channels between the segments.
- the resulting dust is a significant problem. It contaminates the processing device and can penetrate through the seals into the bearings of the spindle and destroy them by its abrasive behavior. In general, the dust that contaminates the entire processing device increases the wear of the parts driving the tool. This reduces the service life of the processing device. Furthermore, it has proven to be problematic that the machining process causes a considerable heat development, so that the tool and the machining itself are exposed to a high thermal load. All this results in the reduction of the maximum grinding speed and the reduction of the grinding quality.
- 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.
- 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 according to the teaching of claim 1.

This not only protects the processing device from the action of dust, it also becomes possible to significantly reduce the operating temperature, since the air jet guided by the tool cools it.
- the means for supplying fluid, ie in particular air, to the center of rotation of the tool is designed as a hollow shaft which serves as a spindle of the tool.
- the hollow shaft can be coaxially mounted in a substantially cylindrically shaped drive motor.
- the width of the fluid channel decreases with increasing radial distance from the center of rotation; In this case is advantageous to a linear decrease - at least over a section - thought.
- the base body and / or the cover body has at least one guide surface, along which the fluid, in particular air, can be passed from the center of rotation of the tool to the at least one cutting element;
- the cover body has this guide surface.
- the guide surface may extend straight or curved between the center of rotation of the tool and the cutting element, wherein in particular a helical formation is provided. Thereafter, the guide surface is thus formed in the manner of a turbine blade, so that upon rotation of the tool creates a conveying effect for the air.
- a structurally particularly simple embodiment of the processing device according to the invention is achieved when the tool has a base body and a cover body, between which the at least one fluid channel is formed.
- both the main body and the cover body may be formed substantially rotationally symmetrical.
- the main body may be formed conically on its side facing the fluid channel, at least over a portion. Accordingly, the cover body can be formed flat on its side facing the fluid channel.
- the 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 done both actively and passively.
- the means by which the fluid can be passed to the center of rotation of the tool with a fan, a compressor, a pump or the like in communication.
- an active and passive generation of the air flow can also be provided on the device.
- the method for operating the processing device employs the rotating tool provided with at least one cutting element, which is mounted on a spindle and rotationally driven.
- an air is conveyed to the center of rotation of the tool and from there via a fluid channel to the at least one cutting element, wherein the air, preferably before their entry into the means, liquid is added.
- the liquid is preferably water.
- the liquid is finely distributed in the air, in particular in the form of droplets.
- a brick 15 is shown, which must be ground flat prior to its use on the end sides. For this purpose, it is conveyed in the direction of the arrow by a processing device, which is shown only very schematically in the figure. Shown are four grinding wheels, two of which are arranged one behind the other in the conveying direction, which are positioned on both sides of the plane surfaces of the brick 15. When passing the brick 15 on the tools 2, it is ground to the required or desired level.
- a processing device 1 which serves this purpose.
- the processing device 1 has a tool 2, which is designed as a grinding wheel.
- the tool 2 rotates about a center of rotation 3; at a distance from this center of rotation 3 are a number of cutting elements 4 - arranged here - in the form of a Schleifbesatzes - on the circumference of the tool 2.
- the tool 2 is rotatably mounted via a spindle 5, wherein the spindle 5 is driven by a drive motor 8.
- the spindle is designed as a hollow shaft, so that the inner portion of the hollow shaft acts as a means 6 for supplying air.
- the air is conveyed by a blower 14 in the hollow shaft.
- the air is deflected in the radial direction and conveyed via the fluid channel 7 as far as the cutting elements 4.
- the tool is constructed as follows: It has a Base body 9, which is formed substantially rotationally symmetrical, as in Fig. 3a can be seen. At the side facing away from the hollow shaft 6 side 11 of the base body 9 is conical. This side 11 of the base body 9 is covered by a cover 10, which in the Fig. 4a and 4b you can see. As it is best in Fig. 2 can be seen, thus forms between the side 11 of the base body 9 and the side 12 of the cover body 10 of the fluid channel 7, whose width B becomes smaller with increasing radius.
- the covering body 10 has a deflecting section 16 which has a favorable flow design (see FIG. Fig. 4b ), which deflects in the axial direction by the hollow shaft 6 on the deflection section 16 impinging air in the radial direction and conveys into the fluid channel 7.
- the air can be promoted by a blower 14 in the hollow shaft 6.
- a blower 14 in the hollow shaft 6.
- air conveying devices in the form of guide surfaces 13 can be arranged on the cover body 10, which have the consequence that upon rotation of the tool (see arrow of the direction of rotation in Fig. 4a ) Air is sucked in via the hollow shaft 6 and conveyed through the fluid channel 7 in the direction of the cutting element 4.
- the guide surfaces 13 are formed turbine blade similar, whereby the delivery effect is accomplished.
- the cutting elements 4 are screwed as interchangeable inserts to the base body 9.
- a device can be integrated with the water in droplet form can be introduced into the air jet. This can be achieved that increases the heat capacity of the fluid jet, so that the ability to dissipate heat at the location of the cutting element 4 is improved. In the same way dust can be bound and removed.

Description
Die Erfindung betrifft eine Schleif- oder Fräsvorrichtung gemäß dem Oberbegriff des Anspruchs 1, zum Planieren von Steinen . Des weiteren betrifft die Erfindung ein Verfahren zum Betreiben der Schleif- oder Fräsvorrichtung gemäß dem Oberbegriff des Anspruchs 13. Eine solche Vorrichtung und zugehöriges Betreibungsverfahren sind aus dem Dokument
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 of bricks or stone blanks or similar ceramic workpieces, arises, inter alia, the task to grind such stones on parallel surfaces or to mill to bring them to the required or desired level ,

Aus der
In der
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 Maßschleifen a stone by means of said processing device, the resulting dust is a significant problem. It contaminates the processing device and can penetrate through the seals into the bearings of the spindle and destroy them by its abrasive behavior. In general, the dust that contaminates the entire processing device increases the wear of the parts driving the tool. This reduces the service life of the processing device. Furthermore, it has proven to be problematic that the machining process causes a considerable heat development, so that the tool and the machining itself are exposed to a high thermal load. All this results in the reduction of the maximum grinding speed and the reduction of 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.
Damit ist es Aufgabe der Erfindung, gegenüber den aus dem Stand der Technik bekannten Schleif- oder Fräsvorrichtungen höhere Arbeitsleistungen und größere Schnitttiefen unter Verzicht auf eine Flüssigkeitskühlung mit entsprechend aufwändigen Flüssigkeitszu- und abfuhreinrichtungen zu erreichen.Thus, it is an object of the invention to achieve over the known from the prior art grinding or milling devices higher performance and greater depths of cutting waiving a liquid cooling with correspondingly complex Flüssigkeitszu- and discharge devices.
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 nach der Lehre des Anspruchs 1.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 according to the teaching of
Demgemäss ist also vorgesehen, dass die Bearbeitungsvorrichtung so ausgeführt ist, dass es möglich wird, eine vom Zentrum des Bearbeitungswerkzeugs ausgehende Luftströmung bis zum Rand des Werkzeugs zu den Schneidelementen zu leiten und dadurch zum einen den anfallenden Staub nach außen abzutransportieren und zum anderen eine Kühlung der Werkzeugeingriffsflächen zu bewirken. 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 is designed so that it is possible to direct an outgoing from the center of the processing tool air flow to the edge of the tool to the cutting elements and thereby on the one hand the dust to be transported to the outside and on the other a cooling of Effect tool engagement surfaces. This not only protects the processing device from the action of dust, it also becomes possible to significantly reduce the operating temperature, since the air jet guided by the tool cools it.
Erfindungsgemäß 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 the invention, it is provided that the means for supplying fluid, ie in particular air, to the center of rotation of the tool is designed as a hollow shaft which serves as a spindle of the tool. The hollow shaft can be coaxially mounted in a substantially cylindrically shaped drive motor.
Weiterhin nimmt erfindungsgemäß die Breite des Fluidkanals mit steigendem radialen Abstand vom Drehzentrum ab; hierbei ist vorteilhaft an eine lineare Abnahme - zumindest über einen Abschnitt - gedacht.Furthermore, according to the invention, the width of the fluid channel decreases with increasing radial distance from the center of rotation; In this case is advantageous to a linear decrease - at least over a section - thought.
Erfindungsgemäß sind zur passive Erzeugung der Luftströmung 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.According to the invention for passive generation of the air flow elements (air conveyors) are provided in the processing device, which themselves generate the air flow without a blower or the like. Advantageously, it is provided for this purpose that the base body and / or the cover body has at least one guide surface, along which the fluid, in particular air, can be passed from the center of rotation of the tool to the at least one cutting element; In particular, the cover body has this guide surface. The guide surface may extend straight or curved between the center of rotation of the tool and the cutting element, wherein in particular a helical formation is provided. Thereafter, the guide surface is thus formed in the manner of a turbine blade, so that upon rotation of the tool creates a conveying effect for the air.
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.A structurally particularly simple embodiment of the processing device according to the invention is achieved when the tool has a base body and a cover body, between which the at least one fluid channel is formed. In this case, both the main body and the cover body may be formed substantially rotationally symmetrical.
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 main body may be formed conically on its side facing the fluid channel, at least over a portion. Accordingly, the cover body can be formed flat on its side facing the fluid channel.
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 sein.The 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 done both actively and passively. This is to be understood that in a case, that is, when actively generating the air flow, the means by which the fluid can be passed to the center of rotation of the tool, with a fan, a compressor, a pump or the like in communication. Of course, if required, an active and passive generation of the air flow can also be provided on the device.
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 Luft zum Drehzentrum des Werkzeugs und von dort über einen Fluidkanal zu dem mindestens einen Schneidelement geleitet wird, wobei der Luft, vorzugsweise vor deren Eintritt in die Mittel, Flüssigkeit zugegeben wird. Die Flüssigkeit ist bevorzugt Wasser. Dabei wird verfahrensgemäß die Flüssigkeit der Luft fein verteilt, insbesondere in Form von Tröpfchen, zugegeben.The method for operating the processing device, preferably for leveling stones, employs the rotating tool provided with at least one cutting element, which is mounted on a spindle and rotationally driven. According to the invention, it is provided that an air is conveyed to the center of rotation of the tool and from there via a fluid channel to the at least one cutting element, wherein the air, preferably before their entry into the means, liquid is added. The liquid is preferably water. According to the method, the liquid is finely distributed in the air, in particular in the form of droplets.
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 procedure according to the method it is achieved that both the Staubableiteffekt and the cooling effect can be increased. The air flowing through the tool is thus provided with water, so that a fine mist is formed whose cleaning and cooling effect is substantially higher than that of pure air.
