Description

Die Erfindung betrifft eine Bearbeitungseinrichtung zum Einsatz in einer Vorrichtung zur mechanischen Oberflächen- und/oder Kantenbearbeitung von Schneidwerkzeugen, insbesondere zum Verrunden der Schneidkante(n) von Schneidplatten oder dergleichen, mit wenigstens einem durch einen Antrieb in Relativbewegung zu dem zu bearbeitenden Bereich des Schneidwerkzeuges versetzbaren und zur Oberflächen- und/oder Kantenbearbeitung mit den entsprechenden Bereichen des Schneidwerkzeuges in Kontakt bringbaren Bearbeitungsmittel (siehe z.B. DE-A-3 116 327 ).The invention relates to a processing device for use in a device for mechanical surface and / or edge processing of cutting tools, in particular for rounding the cutting edge (s) of inserts or the like, with at least one displaceable by a drive in relative movement to the region of the cutting tool to be machined and for surface and / or edge processing with the corresponding areas of the cutting tool brought into contact with processing means (see, eg DE-A-3 116 327 ).

Bei der Schneidwerkzeugherstellung ergibt sich häufig die Notwendigkeit, die nach dem Schleifprozess scharfe Schneidkante gezielt zu verrunden, wobei Größe und Form der Verrundung vom späteren Einsatz des Schneidwerkzeuges abhängen. Dabei ist die Qualität und Präzision der Verrundung sowohl für die Haltbarkeit des Schneidwerkzeuges als auch für die Güte des Bearbeitungsergebnisses beim Einsatz des Schneidwerkzeuges von großer Bedeutung.In the manufacture of cutting tools, there is often the need to purposefully round the sharp cutting edge after the grinding process, the size and shape of the rounding depending on the subsequent use of the cutting tool. The quality and precision of the rounding is of great importance both for the durability of the cutting tool and for the quality of the machining result when using the cutting tool.

Aus der Praxis sind derartige Bearbeitungseinrichtungen in verschiedensten Ausführungsformen bekannt.From practice such processing devices are known in various embodiments.

Neben Sandstrahlen und Trommelieren ist eine Bearbeitung mit einer bürstenförmigen Bearbeitungseinrichtung am stärksten verbreitet, wobei solche Bürsten aus einer mit elastischen Borsten besetzten und um ihre Längsachse rotierenden Walze bestehen.In addition to sandblasting and tumbling, machining with a brush-type machining device is the most widespread, such brushes being made of a roller which is occupied by elastic bristles and rotating about its longitudinal axis.

Nachteilig hierbei ist, dass durch die großen Dimensionen derartiger Bürsten nur beschränkt zur Verrundung von Schneidwerkzeugen eingesetzt werden können.The disadvantage here is that only limited to the rounding of cutting tools can be used by the large dimensions of such brushes.

Bei heutzutage weit verbreiteten Schneidplatten mit unterschiedlichen Kantenhöhen, so genannten "gewaveten" Schneidplatten, lassen sich z. B. solche Bürsten nicht einsetzen, da das Verrundungsergebnis von der Eingriffstiefe abhängt und diese durch die verschiedenen hohen Bereiche der Schneidplatten unterschiedlich sind.In today's widespread inserts with different edge heights, so-called "gewaveten" inserts, can be z. B. such brushes do not use, since the rounding result depends on the depth of engagement and these are different by the different high areas of the inserts.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und eine Bearbeitungseinrichtung anzugeben, mit der eine Bearbeitung von Schneidwerkzeugen mit verschieden hohen Bereichen bei guten Bearbeitungsergebnissen möglich ist.The object of the invention is to avoid the aforementioned disadvantages and to provide a processing device with which a machining of cutting tools with different heights is possible with good processing results.

Diese Aufgabe wird gelöst durch eine Bearbeitungseinrichtung gemäß Anspruch 1 zum Einsatz in einer Vorrichtung zur mechanischen Oberflächen- und/oder Kantenbearbeitung von Schneidwerkzeugen, insbesondere zum Verrunden der Schneidkante(n) von Schneidplatten oder dergleichen, mit wenigstens einem durch einen Antrieb in Relativbewegung zu dem zu bearbeitenden Bereich des Schneidwerkzeuges versetzbaren und zur Oberflächen- und/oder Kantenbearbeitung mit den entsprechenden Bereichen des Schneidwerkzeuges in Kontakt bringbaren Bearbeitungsmittel, wobei die Bearbeitungseinrichtung zumindest ein als längliches, im Wesentlichen zylinderförmig ausgebildetes und durch den mit der Bearbeitungseinrichtung verbundenen Antrieb in eine rotatorische Bewegung um eine zur Längserstreckung im Wesentlichen parallele Achse versetzbares Bearbeitungsmittel aufweist, wobei mehrere als flexible Bearbeitungsbürstfäden ausgebildete, insbesondere verschlungene oder miteinander verflochtene Bearbeitungsmittel vorgesehen sind, die aus Kunststoff oder Metall bestehen und mit Abrasivstoffen besetzt und/oder durchsetzt sind und wobei die Bearbeitungsbürstfäden in einem länglichen, insbesondere kreiszylinderförmigen Hohlkörper vorgesehen und endseitig aus dem Hohlkörper herausragend angeordnet sind und die Bearbeitungsmittel durch eine Vorschubeinrichtung, insbesondere auch während des Bearbeitungsbetriebes nachführbar sind, so dass ein Ausgleich der Abnutzung durch die Bearbeitung, entweder in Bearbeitungspausen oder aber kontinuierlich während der Bearbeitung erfolgt.This object is achieved by a processing device according to claim 1 for use in a device for mechanical surface and / or edge processing of cutting tools, in particular for rounding the cutting edge (s) of inserts or the like, with at least one by a drive in relative movement to the machining area of the cutting tool displaceable and for surface and / or edge processing with the corresponding areas of the cutting tool in contact-engageable processing means, wherein the processing means at least one as elongated, substantially cylindrical trained and by the connected to the processing device drive in a rotational movement about a longitudinal extent substantially parallel axis displaceable processing means, wherein a plurality of flexible Bearbeitungsbürstfäden trained, in particular intertwined or intertwined processing means are provided which consist of plastic or metal and with abrasives are occupied and / or interspersed and wherein the Bearbeitungsbürstfäden provided in an elongated, in particular circular cylindrical hollow body and the end of the hollow body are outstanding and the processing means are trackable by a feed device, in particular during the processing operation, so that a balance of wear by machining , either during processing breaks or continuously during processing .

Hierdurch kann die Bearbeitung der entsprechenden Bereiche des Schneidwerkzeuges wesentlich genauer erfolgen, da das Bearbeitungsmittel gegenüber üblichen Bürsten deutlich kleiner ausgebildet werden kann. Bürsten in entsprechend kleiner Form sind insofern nicht möglich, da aufgrund der dann sehr kurzen Borstenlänge bei üblichem Verschleiß nur eine sehr kurze Einsatzdauer möglich wäre. Weiterhin entfällt der bei üblichen Bürsten mit einem großen Durchmesser erforderliche Platzbedarf, so dass die Bearbeitungsvorrichtung ebenfalls kleiner und kostengünstiger ausgebildet sein kann. Dabei kann die Rotation kontinuierlich erfolgen oder als kurze Intervalle in jeweils entgegengesetzter Drehrichtung ausgebildet sein.In this way, the processing of the corresponding areas of the cutting tool can be done much more accurately, since the processing means can be made significantly smaller compared to conventional brushes. Brushes in a correspondingly small shape are not possible, since only a very short service life would be possible due to the then very short bristle length with conventional wear. Furthermore, eliminates the space required for conventional brushes with a large diameter space, so that the processing device can also be made smaller and cheaper. In this case, the rotation can take place continuously or be designed as short intervals in each opposite direction of rotation.

Auch wird eine größere Flexibilität der Bearbeitungsmittel ermöglicht, so dass eine schonendere Bearbeitung möglich ist und durch die Flexibilität ein Ausgleich von Unebenheiten oder dergleichen erfolgen kann. Dabei können die zwischen den einzelnen Bearbeitungsbürstfäden verbleibenden Freiräume mit einem beispielsweise aus Kunststoff bestehenden Bindemittel aufgefüllt sein, so dass eine höhere Stabilität gegeben ist.Also, a greater flexibility of the processing means is made possible, so that a gentler processing possible is and can be done by the flexibility of a compensation of bumps or the like. In this case, the remaining between the individual Bearbeitungsbürstfäden open spaces can be filled with an existing example of plastic binder, so that a higher stability is given.

Ferner wird eine gute seitliche Führung gewährleistet und Bearbeitungsbeeinträchtigung durch Verlagerung der Bearbeitungsbürstfädenenden oder ungewolltes Auffächern des Bearbeitungsbürstfädenbündels wird vermieden.Furthermore, a good lateral guidance is ensured and processing impairment due to displacement of the processing brush thread ends or unintentional fanning of the processing brush thread bundle is avoided.

Zudem kann ein Ausgleich der Abnutzung durch die Bearbeitung, entweder in Bearbeitungspausen oder aber kontinuierlich während der Bearbeitung erfolgen.In addition, a compensation of the wear by the machining, either in processing breaks or continuously during processing.

Dabei können die Breite und Tiefe bzw. der Durchmesser des Hohlkörpers klein sein, insbesondere in etwa 2 bis 20 mm betragen.In this case, the width and depth or the diameter of the hollow body can be small, in particular be approximately 2 to 20 mm.

Auch kann eine Fixiereinrichtung gegen Verlagerung der Bearbeitungsbürstfäden entgegen der rotatorischen Bewegung im Hohlkörper vorgesehen sein, so dass der Hohlkörper angetrieben werden kann und die Bearbeitungseinrichtung einfacher aufgebaut sein kann.Also, a fixing device may be provided against displacement of the processing brush threads against the rotational movement in the hollow body, so that the hollow body can be driven and the processing device can be constructed simpler.

Hierbei kann die Fixiereinrichtung eine Klemmeinrichtung beinhalten.In this case, the fixing device may include a clamping device.

Die Fixiereinrichtung kann aber auch zumindest eine sich radial in dem Hohlkörper erstreckende Trenneinrichtung, insbesondere eine Trennwand oder dergleichen aufweisen, so dass mit einfachen konstruktiven Mitteln die Bewegung des Antriebs von dem Hohlkörper auf die Bearbeitungsmittel übertragbar ist.However, the fixing device may also have at least one radially extending in the hollow body separating device, in particular a partition or the like, so that with simple structural means the movement of the Drive is transferable from the hollow body to the processing means.

Sofern als Fixiereinrichtung eine Klemmeinrichtung vorgesehen ist, kann diese in Nachführrichtung verlagerbar sein und/oder während des Nachführens kurzfristig deaktiviert werden.If a clamping device is provided as a fixing device, it may be displaceable in the tracking direction and / or temporarily deactivated during the tracking process.

Die der Erfindung zugrunde liegende Aufgabe wird weiterhin gelöst durch eine Bearbeitungseinrichtung gemäß Anspruch 6 zum Einsatz in einer Vorrichtung zur mechanischen Oberflächen- und/oder Kantenbearbeitung von Schneidwerkzeugen, insbesondere zum Verrunden der Schneidkante(n) von Schneidplatten oder dergleichen, mit wenigstens einem durch einen Antrieb in Relativbewegung zu dem zu bearbeitenden Bereich des Schneidwerkzeuges versetzbaren und zur Oberflächen- und/oder Kantenbearbeitung mit den entsprechenden Bereichen des Schneidwerkzeuges in Kontakt bringbaren Bearbeitungsmittel, wobei die Bearbeitungseinrichtung zumindest ein als längliches, im Wesentlichen zylinderförmig ausgebildetes und durch den mit der Bearbeitungseinrichtung verbundenen Antrieb in eine rotatorische Bewegung um eine zur Längserstreckung im Wesentlichen parallele Achse versetzbares Bearbeitungsmittel aufweist und wobei ein als Bearbeitungsschleifstift ausgebildetes Bearbeitungsmittel vorgesehen ist, das gummi-, silikon- oder kunststoffgebunden ist und abrasive Bestandteile aufweist und wobei der Bearbeitungsschleifstift ferner in einem länglichen, seiner Kontur angepassten Hohlkörper vorgesehen und endseitig aus dem Hohlkörper herausragend angeordnet ist und wobei die Bearbeitungsmittel durch eine Vorschubeinrichtung, insbesondere auch während des Bearbeitungsbetriebes nachführbar sind, so dass ein Ausgleich der Abnutzung durch die Bearbeitung, entweder in Bearbeitungspausen oder aber kontinuierlich während der Bearbeitung erfolgt..The object underlying the invention is further achieved by a processing device according to claim 6 for use in a device for mechanical surface and / or edge processing of cutting tools, in particular for rounding the cutting edge (s) of inserts or the like, with at least one by a drive in machining relative to the machined portion of the cutting tool displaceable and for surface and / or edge processing with the corresponding areas of the cutting tool in contact processing means, wherein the processing means at least one as an elongated, substantially cylindrically shaped and connected by the associated with the processing device drive in a rotational movement about a longitudinal axis to the substantially parallel axis displaceable processing means and wherein a trained as a Bearbeitungsschleifstift processing means is provided, the gu mmi-, silicone- or plastic-bonded and having abrasive constituents and wherein the Bearbeitungsschleifstift also provided in an elongated contour adapted to its hollow body and the end of the hollow body protruding and wherein the processing means are tracked by a feed device, in particular during the processing operation, so as to compensate for the wear caused by the machining, either during processing breaks or continuously during processing ..

Hierdurch wird ein leicht herzustellendes Bearbeitungsmittel angegeben, das eine flächige Bearbeitung in sehr kleinen Dimensionen ermöglicht und einerseits aufgrund seiner massiven Formgebung und andererseits aufgrund des ihn umgebenden Hohlkörpers sehr stabil und gut gestützt ist. Bearbeitungsstifte erzielen sehr gute Abtragsergebnisse und können einer zu bearbeitenden Kontur genau nachgeführt werden.As a result, an easy-to-produce processing means is specified, which enables a flat processing in very small dimensions and on the one hand due to its massive shape and on the other hand due to the surrounding hollow body is very stable and well supported. Editing pins achieve very good removal results and can be accurately tracked to a contour to be machined.

Die Erfindung betrifft auch eine Vorrichtung zur mechanischen Oberflächen- und/oder Kantenbearbeitung von Schneidwerkzeugen, insbesondere zum Verrunden der Schneidkante(n) von Schneidplatten oder dergleichen.The invention also relates to a device for mechanical surface and / or edge processing of cutting tools, in particular for rounding the cutting edge (s) of inserts or the like.

Derartige Vorrichtungen sind in verschiedensten Ausführungsformen bekannt. Dabei ist neben Sandstrahlen und Trommelieren eine Bearbeitung mit einer bürstenförmigen Bearbeitungseinrichtung am stärksten verbreitet, wobei solche Bürsten aus einer mit elastischen Borsten besetzten und um ihre Längsachse rotierenden Walze bestehen.Such devices are known in various embodiments. In addition to sandblasting and tumbling, machining with a brush-shaped machining device is most widespread, such brushes consisting of a roller occupied by elastic bristles and rotating about its longitudinal axis.

Nachteilig wirkt sich dabei aus, dass derartige Bürsten aufgrund ihrer großen Dimensionen nur beschränkt zur Verrundung von Schneidwerkzeugen eingesetzt werden können und bei heutzutage weit verbreiteten Schneidplatten mit unterschiedlichen Kantenhöhen, so genannten "gewaveten" Schneidplatten, nicht verwendbar sind, da das Verrundungsergebnis von der Eingriffstiefe abhängt und diese durch die verschiedenen hohen Bereiche der Schneidplatten unterschiedlich sind.The disadvantage of this is that such brushes can only be used to a limited extent for the rounding of cutting tools due to their large dimensions and in today's widespread inserts with different edge heights, so-called "gewaveten" inserts are not usable, since the rounding result depends on the depth of engagement and these are different due to the different high areas of the inserts.

Insofern ist es auch Aufgabe der Erfindung, die vorgenannten Nachteile zu vermeiden und eine derartige Vorrichtung anzugeben, mit der eine Bearbeitung von Schneidwerkzeugen mit verschieden hohen Bereichen bei guten Bearbeitungsergebnissen möglich ist.In this respect, it is also an object of the invention to avoid the aforementioned disadvantages and to provide such a device with which a machining of cutting tools with different heights is possible with good processing results.

Diese Aufgabe wird dadurch gelöst, dass die Vorrichtung eine Bearbeitungseinrichtung gemäß den vorstehenden Ausführungsvarianten aufweist.This object is achieved in that the device has a processing device according to the above embodiments.

Vorzugsweise können die Bearbeitungsmittel in einem Vorratsmagazin z. B. auf Trommeln oder dergleichen aufbewahrt und eine Ausgabeeinrichtung zur entsprechenden Konfektionierung und Zuführung vorgesehen sein, so dass ein umständlicher und zeitaufwendiger Wechsel der Bearbeitungsmittel bei Verschleiß nicht erforderlich ist. Hierbei können in dem Vorratsmagazin auch unterschiedliche Formen und Typen von Bearbeitungsmitteln vorgesehen sein, so dass innerhalb der Vorrichtung eine Anpassung an unterschiedliche Anforderungen hinsichtlich der Bearbeitung erfolgen kann. Unter Konfektionierung ist sowohl ein Kürzen bzw. Abtrennen als auch eine Bearbeitung, z. B. ein Verseilen oder dergleichen der Bearbeitungsmittel zu verstehen.Preferably, the processing means in a storage magazine z. B. on drums or the like and an output device for the corresponding packaging and feeding be provided, so that a cumbersome and time-consuming change of the processing means is not required for wear. In this case, different shapes and types of processing means may also be provided in the supply magazine so that an adaptation to different requirements with regard to the processing can take place within the device. Under confectioning is both a shortening or cutting as well as a processing, eg. As a stranding or the like of the processing means to understand.

Weiterhin kann eine Einrichtung zur Verschlingung oder Verflechtung der Bearbeitungsmittel miteinander vorgesehen sein, so dass durch entsprechende Ausbildung (Verseilen) der Bearbeitungsmittel eine höhere Stabilität des Bearbeitungsmittels erfolgen kann.Furthermore, a device for entanglement or intertwining of the processing means may be provided together, so that a higher stability of the processing means can be achieved by appropriate training (stranding) of the processing means.

Vorzugsweise kann zumindest eine Handhabungseinrichtung zur Veränderung der Position der Bearbeitungseinrichtung vorgesehen sein und/oder es kann zumindest eine Handhabungseinrichtung zur Veränderung der Position des zu bearbeitenden Schneidwerkzeuges vorgesehen sein, so dass eine freie Steuerung der für eine einwandfreie Bearbeitung erforderlichen Bewegungsabläufe möglich ist. Dabei kann die Handhabungseinrichtung entweder als Roboter, insbesondere mit vier oder fünf Achsen ausgebildet sein, die Handhabungseinrichtung kann aber auch als Schwenktisch oder CNC-Maschine ausgeprägt sein. Durch Kombination von verschiedenen Handhabungseinrichtungen für Werkstück einerseits und Werkzeug andererseits sind eine Vielzahl unterschiedlichster Ausprägungen möglich. Durch integrierte Sensoren ist eine Regelung und automatische Prozessrückführung möglich. Auch kann eine Integration in andere robotisierte Maschinen erfolgen.Preferably, at least one handling device can be provided to change the position of the processing device and / or at least one handling device can be used to change the position of the processing device Cutting tool be provided so that a free control of the movements required for proper processing is possible.

Die Erfindung betrifft weiterhin ein Verfahren zur mechanischen Oberflächen- und/oder Kantenbearbeitung von Schneidwerkzeugen, insbesondere zum Verrunden der Schneidkante(n) von Schneidplatten oder dergleichen, mittels einer Bearbeitungseinrichtung, die wenigstens ein durch einen Antrieb in Relativbewegung zu dem zu bearbeitenden Bereich des Schneidwerkzeuges versetzbares und zur Oberflächen- und/oder Kantenbearbeitung mit den entsprechenden Bereichen des Schneidwerkzeuges in Kontakt bringbares Bearbeitungsmittel aufweist.The invention further relates to a method for mechanical surface and / or edge processing of cutting tools, in particular for rounding the cutting edge (s) of inserts or the like, by means of a processing device, the at least one displaceable by a drive in relative movement to the region to be machined of the cutting tool and for surface and / or edge processing with the corresponding areas of the cutting tool has contactable processing means.

Die in der Praxis bekannten Bearbeitungsverfahren sind eingangs einschließlich ihrer Nachteile bereits ausführlich behandelt worden.The processing methods known in practice have already been dealt with in detail, including their disadvantages.

Aufgabe der Erfindung es somit ebenfalls, ein Verfahren zur mechanischen Oberflächenbehandlung dahingehend zu verbessern, dass gute Ergebnisse auch bei der Bearbeitung von Schneidwerkzeugen mit verschieden hohen Bereichen erzielt werden. Dabei kann die Bearbeitung insbesondere durch eine Bearbeitungseinrichtung oder eine Vorrichtung der vorbeschriebenen Art erfolgen.The object of the invention, therefore, likewise to improve a method for mechanical surface treatment in such a way that good results are achieved even when machining cutting tools with different high areas. The processing can in particular by a Machining device or a device of the type described above.

Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 12 gelöst, wobei als flexible Bearbeitungsbürstfäden ausgebildete Bearbeitungsmittel durch den Antrieb in eine rotatorische Bewegung um eine zur Längserstreckung im Wesentlichen parallele Achse versetzt werden und ein Ausgleich der Abnutzung durch die Bearbeitung, entweder in Bearbeitungspausen oder aber kontinuierlich während der Bearbeitung erfolgt. Hierdurch ist eine genauere Bearbeitung der entsprechenden Bereiche des Schneidwerkzeuges möglich.This object is achieved by a method according to claim 12, wherein machining means designed as flexible processing brush threads are offset by the drive in a rotational movement about an axis substantially parallel to the longitudinal extension and a compensation of wear by machining, either during processing breaks or continuously during the processing is done . As a result, a more accurate machining of the corresponding areas of the cutting tool is possible.

Vorzugsweise können als Bearbeitungsmittel mehrere als flexible Bearbeitungsbürstfäden ausgebildete, insbesondere verschlungene oder miteinander verflochtene Bearbeitungsmittel vorgesehen sein, die bei einem bevorzugten Ausführungsbeispiel der Erfindung in einem länglichen, insbesondere kreiszylinderförmigen Hohlkörper der Bearbeitungseinrichtung angeordnet sein können und endseitig aus dem Hohlkörper herausragen können.Preferably, a plurality of processing means designed as flexible processing brush threads, in particular intertwined or intertwined, can be provided which, in a preferred embodiment of the invention, can be arranged in an elongated, in particular circular cylindrical hollow body of the processing device and can protrude from the hollow body at the end.

Dabei können die Bearbeitungsbürstfäden in Abstimmung auf die Rotationsgeschwindigkeit so weit endseitig freistehend sein, dass sie durch die Fliehkraft in eine in etwa schirmförmige Form zur insbesondere seitlichen Bearbeitung ausgelenkt werden. Die Form der schirmförmigen Struktur ist durch die Auskraglänge und die Drehzahl beeinflussbar und kann insofern durch gezielte Steuerung auch während der Bearbeitung beeinflusst werden. Vorzugsweise ist die Längserstreckung der Bearbeitungsbürstfäden in etwa rechtwinklig zu der Rotationsachse und die Bearbeitung erfolgt mit dem Endpunkt der Bearbeitungsbürstfäden.In this case, the Bearbeitungsbürstfäden in coordination with the rotational speed so far end be free-standing that they are deflected by the centrifugal force in an approximately umbrella-like shape for lateral processing in particular. The shape of the umbrella-shaped structure can be influenced by the projecting length and the speed and can thus be influenced by targeted control even during processing. Preferably, the longitudinal extent of the processing brush threads is approximately at right angles to the axis of rotation and the processing takes place with the end point of the processing brush threads.

Fig. 1 zeigt eine erfindungsgemäße Vorrichtung 1 zur mechanischen Oberflächen- und/oder Kantenbearbeitung einer Schneidplatte 2 mit teilweise erhöhten Kantenbereichen 3. Die Vorrichtung 1 weist dabei eine Bearbeitungseinrichtung 4 auf, die ein längliches, im Wesentlichen zylinderförmig ausgebildetes Bearbeitungsmittel 5 aufweist, das durch einen Antrieb 6 in eine rotatorische Bewegung um eine zur Längserstreckung des Bearbeitungsmittels 5 im Wesentlichen parallele Achse versetzbar ist.1 shows a device 1 according to the invention for the mechanical surface and / or edge processing of a cutting plate 2 with partially raised edge regions 3. The device 1 in this case has a processing device 4, which has an elongated, substantially cylindrically shaped processing means 5 by a Drive 6 in a rotational movement about a longitudinal extent of the processing means 5 is substantially parallel axis displaceable.

Dabei kann das Bearbeitungsmittel 5 als Bearbeitungsschleifstift massiv ausgebildet sein, es kann aber auch, wie in den Fig. 2 bis 5 dargestellt, aus mehreren flexiblen Bearbeitungsbürstfäden 7 bestehen. Die Bearbeitungsbürstfäden 7 können beispielsweise aus Kunststoff oder Metall bestehen und mit Abrasivstoffen 8 besetzt und/oder durchsetzt sein (vgl. Fig. 2).In this case, the processing means 5 may be solid as a machining grinding pin, but it may also, as shown in FIGS. 2 to 5, consist of several flexible processing brush threads 7. The processing brush threads 7 can for example consist of plastic or metal and are filled with abrasives 8 and / or interspersed (see Fig. 2).

Wie aus Fig. 3 ersichtlich, können zwischen den einzelnen Bearbeitungsbürstfäden 7 verbleibende Freiräume 9 zumindest teilweise mit einem beispielsweise aus Kunststoff bestehenden Bindemittel 10 aufgefüllt sein, so dass eine höhere Stabilität und eine bessere Verschleißfestigkeit erzielt wird.As can be seen from FIG. 3, free spaces 9 remaining between the individual processing brush threads 7 can at least partially be filled up with a binder 10, for example made of plastic, so that a higher level is achieved Stability and better wear resistance is achieved.

Wie in den Fig. 1 und 4 dargestellt, kann das Bearbeitungsmittel 5 bzw. die Bearbeitungsbürstfäden 7 in einem länglichen, insbesondere kreiszylinderförmigen Hohlkörper 11 vorgesehen und endseitig aus dem Hohlkörper 11 herausragend angeordnet sein.As shown in Figs. 1 and 4, the processing means 5 and the Bearbeitungsbürstfäden 7 may be provided in an elongated, in particular circular cylindrical hollow body 11 and the end of the hollow body 11 may be outstanding.

Entsprechend Fig. 4 können die Bearbeitungsbürstfäden 7 in Abhängigkeit von der Rotationsgeschwindigkeit so weit herausragen, dass eine Ablenkung in eine etwa rechtwinklig zur Mittelachse liegende Ausrichtung erfolgt. Hierbei kann die Bearbeitung entweder mit den seitlichen Endpunkten oder aber durch die somit vergrößerte Stirnfläche erfolgen.According to FIG. 4, the processing brush threads 7 can protrude so far in dependence on the rotational speed that a deflection takes place in an alignment approximately at right angles to the central axis. Here, the processing can be done either with the lateral end points or by the thus enlarged end face.

In Fig. 5 ist eine Fixiereinrichtung 12 gegen Verlagerung der Bearbeitungsbürstfäden 7 entgegen der rotatorischen Bewegung im Hohlkörper 11 dargestellt, wobei die Fixiereinrichtung 12 als sich radial in dem Hohlkörper 11 erstreckende Trennwände 13 ausgebildet ist.5, a fixing device 12 is shown against displacement of the processing brush threads 7 against the rotational movement in the hollow body 11, wherein the fixing device 12 is formed as radially extending in the hollow body 11 partitions 13.
