Description

Die folgende Erfindung betrifft ein Werkzeug zum Bearbeiten von Oberflächen und ein Verfahren zur Herstellung eines solchen Werkzeuges.The following invention relates to a tool for machining surfaces and a method of manufacturing such a tool.

Werkzeuge zum Bearbeiten von Oberflächen sind im Stand der Technik bekannt und dienen unter anderem zum Abrichten von Werkstücken, bei denen mit einem Werkzeug insbesondere eine Feinbearbeitung der Oberfläche stattfindet. Hierzu wird das rotierende Abrichtwerkzeug, das u. a. eine definierte Bearbeitungsfläche aufweiset, über den zu bearbeitenden Körper geführt, um das Werkstück entsprechend den Vorgaben und Toleranzen zu bearbeiten.Tools for machining surfaces are known in the art and are used, among other things, for dressing workpieces in which, in particular, fine machining of the surface takes place with a tool. For this purpose, the rotating dressing tool, the u. a. having a defined working surface, passed over the body to be machined to machine the workpiece according to the specifications and tolerances.

Zur Bearbeitung dient bei einem solchen Werkzeug im Wesentlichen die Bearbeitungsfläche, die als mit Schleifkörpern besetzte Oberfläche des Werkzeugs Material vom Werkstück abträgt, wobei dies sowohl mit dem Umfang als auch mit den Seitenflächen des Werkzeuges erfolgen kann.For machining, such a tool essentially serves as the machining surface, which removes material from the workpiece as the surface of the tool occupied by the abrasive bodies, and this can be done both with the circumference and with the side surfaces of the tool.

Nachteilig bei solchen Werkzeugen des Standes der Technik ist es jedoch, dass die Herstellung eines solchen Werkzeuges sehr aufwendig ist. Dies ist unter anderem darin begründet, dass die Werkzeuge individuell an die zu bearbeitende Oberflächenstruktur und -form angepasst werden müssen. Ferner ist es schwierig, sehr feine Bearbeitungswerkzeuge bereitzustellen, da mit den im Stand der Technik bekannten Herstellungsverfahren nur Werkzeuge, insbesondere Bearbeitungsscheiben, zur Verfügung gestellt werden, deren Stabilität und damit deren Präzision durch die Materialstärke im Außenbereich der Bearbeitungsscheibe und deren Fähigkeiten begrenzt ist.A disadvantage of such tools of the prior art, however, is that the production of such a tool is very expensive. This is partly due to the fact that the tools must be adapted individually to the surface structure and shape to be machined. Furthermore, it is difficult to provide very fine machining tools, since with the known in the prior art manufacturing process only tools, especially machining discs, are provided, their stability and thus their precision is limited by the material thickness in the outer region of the machining disk and their capabilities.

Ferner sind auch Verfahren zur Herstellung von Formrollen, insbesondere für die Bearbeitung von Oberflächen, im Stand der Technik bekannt. So zeigt beispielsweise die EP 0 922 533 A2 eine Abrichtrolle für Schleifscheiben gemäß dem Oberbegriff des Anspruchs 1, der Diamantschleifscheiben zwischen zwei Stützscheiben angeordnet werden, und welche jeweils einen Ring- und einen Kegelscheibenabschnitt aufweisen und Montage- bzw. Aufnahmebuchse umfassen. Die einzelnen Bauteile der Abrichtrolle werden durch Schrauben gegeneinander verspannt, welche durch Bohrungen, die unter anderem in den Stützscheiben vorgeformt sind, hindurchgeführt werden. Die Diamanten werden hierbei in den Diamantschleifacheiben mechanisch gefasst.Furthermore, methods for producing molded rolls, in particular for the treatment of surfaces, are also known in the art. For example, shows the EP 0 922 533 A2 a dressing wheel for grinding wheels according to the preamble of claim 1, the diamond grinding wheels are arranged between two support disks, and which each have a ring and a conical disk portion and comprise mounting or receiving socket. The individual components of the dressing roller are clamped by screws against each other, which are passed through holes which are preformed, inter alia, in the support disks. The diamonds are mechanically gripped in the diamond grinding discs.

Nachteilig bei solchen Abrichtrollen ist es jedoch, dass durch die Bohrungen und die hierin angeordneten Schrauben die Massenverteilung in Bezug auf die Rotationsachsen der Rolle ungleichmäßig ist und andererseits Verspannungen innerhalb der Abrichtrolle auftreten können, die neben einer reduzierten Maßhaltigkeit. d. h. Präzision, der so zusammengesetzten Abrichtrollen auch zu einer verschlechterten Lebensdauer dieser Abrichtrollen führtA disadvantage of such dressing rolls, however, is that through the holes and the screws arranged therein, the mass distribution with respect to the axes of rotation of the roll is uneven and on the other hand tensions can occur within the dressing roll, in addition to a reduced dimensional stability. d. H. Precision, the composite dressing rolls also leads to a deteriorated life of these dressing rolls

Aufgabe der vorliegenden Erfindung ist es somit, ein Bearbekungswerkzeug sowie ein Verfahren zu dessen Herstellung bereitzustellen, das wenigstens teilweise die im Stand der Technik bekannten Nachteile überwindet bzw. verbessert und insbesondere die Qualität bezüglich der Maßhaltigkeit entsprechender Werkzeuge für den Einsatz zur Bearbeitung von Oberflächen wenigstens teilweise erhöht.The object of the present invention is therefore to provide a machining tool and a method for its production which at least partially overcomes or improves the disadvantages known in the prior art and in particular the quality with respect to the dimensional accuracy of corresponding tools for use for machining surfaces at least partially elevated.

Gelöst wird diese Aufgabe durch ein Werkzeug zur Bearbeitung von Oberflächen gemäß Anspruch 1. Ferner wird die Aufgabe auch durch ein Herstellungsverfahren für ein solches Werkzeug gemäß Anspruch 12 gelöst. Bevorzugte Ausführungsformen sind Gegenstand der Unteransprüche.This object is achieved by a tool for machining surfaces according to claim 1.

The receiving device preferably comprises at least one spindle with a plug connection, on which preferably at least one or a multiplicity of machining disks are received axially.

The tool according to the invention has a uniform mass distribution with respect to its axis of rotation.

Die zentrale Öffnung zur Aufnahme der Steckverbindung kann sowohl kreisförmig, als auch polygonförmig sein oder andere entsprechende Formen aufweisen, um insbesondere eine ausreichende Basisverbindung zwischen der Aufnahmevorrichtung und der Bearbeitungsscheibe bereitzustellen.
Insbesondere die kreisförmige Öffnung der Bearbeitungsscheibe und die entsprechende kreisförmige Ausführungsform der Steckverbindung sind allerdings bevorzugt.The central opening for receiving the connector may be both circular, as well as polygonal or have other corresponding shapes, in particular to provide a sufficient base connection between the receiving device and the machining disk.
In particular, however, the circular opening of the machining disk and the corresponding circular embodiment of the connector are preferred.

Gemäß einer weiteren besonders bevorzugten Ausführungsform weist das Werkzeug eine Mehrzahl von Bearbeitungsscheiben aus einem Basismaterial auf, welches aus einer Gruppe ausgewählt ist, die Sintermaterialien, metallische Bronzeverbindungen, Kunststoffe wie Phenolharzverbindungen, Keramiken und Kombinationen hiervon enthält. Die Bearbeitungsscheiben sind stoffschlüssig zu einem Stapel miteinander verbunden, wobei die stoffschlüssige Verbindung mittels Kunststoff-Klebstoffen und/oder Lötzinn hergestellt ist. Die Bearbeitungsscheiben sind axial auf der Aufnahmevorrichtung aufgenommen. Dabei können die Bearbeitungsscheiben gemäß einer weiteren besonders bevorzugten Ausführungsform unterschiedliche Dicken aufweisen und sind bevorzugt miteinander stoffschlüssig verbunden.According to another particularly preferred embodiment, the tool comprises a plurality of machining disks of a base material selected from a group comprising sintered materials, metallic bronze compounds, plastics such as phenolic resin compounds, ceramics and combinations thereof. The machining discs are materially connected to form a stack, wherein the cohesive connection is made by means of plastic adhesives and / or solder. The processing discs are received axially on the receiving device. In this case, according to a further particularly preferred embodiment, the machining disks can have different thicknesses and are preferably connected to one another in a material-bonded manner.

Die stoffschlüssige Verbindung der Bearbeitungsscheiben kann sowohl vor dem Zusammensetzen der Bearbeitungsscheiben mit der Aufnahmevorrichtung als auch nach dem Zusammensetzen oder mit dem Zusammensetzen der Aufnahmevorrichtung erfolgen.The cohesive connection of the machining disks can be carried out both before assembly of the processing disks with the receiving device and after assembly or with the assembly of the receiving device.

Gemäß einer weiteren besonders bevorzugten Ausführungsform weisen die Bearbeitungsscheiben unterschiedliche Bearbeitungsflächen auf, wobei beispielsweise die äußere Bearbeitungsscheibe an der nach außen gerichteten Bearbeitungsfläche wenigstens abschnittsweise Schleifkörper aufweisen und die mittleren Bearbeitungsscheiben vorzugsweise im Bereich des Umfangs entsprechende Schleifkörper zum Bearbeiten der Oberflächen aufweisen kann. Dies kann insbesondere den entsprechenden Anforderungen an die Bearbeitung eines Werkstücks angepasst werden.According to a further particularly preferred embodiment, the processing disks have different processing surfaces, wherein, for example, the outer processing disk at the outwardly directed processing surface at least partially abrasive and have the middle processing discs preferably in the region of the circumference corresponding abrasive body for processing the surfaces. This can be adapted in particular to the corresponding requirements for the machining of a workpiece.

Das Zusammensetzen verschiedener Bearbeitungsscheiben zu einem Stapel von Bearbeitungsscheiben, die auf einer Aufnahmevorrichtung aufgenommen sind, hat insbesondere den Vorteil, dass auf die Eigenschaften der Bearbeitungsscheibe zum Bearbeiten von Oberflächen unterschiedlich Einfluss genommen werden kann und durch die Verbindung der Bearbeitungsscheiben miteinander eine zusätzliche Stabilität im Sinne einer "Sandwichbauweise" erzielt werden kann.The composition of different processing disks to a stack of processing disks, which are accommodated on a receiving device, has the particular advantage that the properties of the processing disk for processing surfaces can be influenced differently and by the combination of the processing disks together an additional stability in terms of "Sandwich construction" can be achieved.

So liegt es auch im Sinn der vorliegenden Erfindung, dass unterschiedliche Schleifkörper für die verschiedenen Bearbeitungsscheiben verwendet werden, wobei beispielsweise zur Bearbeitung der Seiten gröbere Schleifkörper verwendet werden als am Umgangsbereich. Auch die Kombination verschiedener Schleiflcörperarten liegt im Sinn der vorliegenden Erfindung.Thus, it is also within the meaning of the present invention that different grinding wheels are used for the different machining disks, for example, coarser grinding wheels being used for machining the sides than at the contact area. The combination of different Schleiflbörperarten lies within the meaning of the present invention.

Als Schleifkörper, die zur Bearbeitung der Oberfläche verwendet werden und die Bearbeitungsflächen vorzugsweise bilden, werden Schleifkörper aus einer Gruppe ausgewählt, die insbesondere Diamantnadeln wie beispielsweise PKD-, MKD-, CVD-, CBN-Nadeln enthält.As abrasive bodies used for machining the surface and preferably forming the machining surfaces, abrasive bodies are selected from a group including, in particular, diamond needles such as PCD, MKD, CVD, CBN needles.

Die Schleifkörper für das Werkzeug, welche die Bearbeitungsfläche bilden, sind im Wesentlichen stoffschlüssig mit der Bearbeitungsscheibe verbunden. Dies kann beispielsweise dadurch erfolgen, dass die Schleifkörper mit einer metallischen oder einer Kunststoffverbindung auf der Bearbeitungsscheibe fixiert werden oder gemäß einer weiteren besonders bevorzugten Ausführungsform bei der Herstellung der Bearbeitungsscheibe bereits mit dieser stoffschlüssig verbunden werden.The grinding wheels for the tool, which form the working surface, are connected substantially in a materially bonded manner to the machining disk. This can be done, for example, by fixing the abrasive bodies with a metallic or a plastic connection on the machining disk or, in accordance with a further particularly preferred embodiment, during the production of the machining disk, already being adhesively bonded thereto.

Gemäß einer weiteren besonders bevorzugten Ausführungsform weist die Bearbeitungsscheibe in axialer Richtung unterschiedliche Materialschichten und Materialarten auf, die insbesondere in der Art aufeinander abgestimmt sind, dass durch die Kombination der verschiedenen Materialdichten, sowohl die notwendigen Festigkeitseigenschaften der Bearbeitungsscheibe als auch insbesondere im Hinblick auf die Bearbeitung von Oberflächen und der hierbei entstehenden Wärme eine ausgleichende Abführung der Wärme vom Werkstück über die Bearbeitungsscheibe und die Aufnahmevorrichtung bereitgestellt wird.According to a further particularly preferred embodiment, the machining disk in the axial direction on different material layers and types of material, which are particularly matched in the manner that by the combination of different material densities, both the necessary strength properties of the machining disk and in particular with regard to the processing of Surfaces and the resulting heat is provided a compensatory removal of heat from the workpiece on the processing disk and the receiving device.
