Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Besetzen von metallischen Werkzeugen, insbesondere Bürstenwerkzeugen mit Schleifmittelteilchen, wie bspw. aus Diamant, kubischem Bornitrid, Korund und dgl., und auf ein nach diesem Verfahren hergestelltes metallisches Werkzeug, insbesondere Bürstenwerkzeug.The present invention relates to a method for filling metallic tools, in particular brush tools with abrasive particles such as, for example, made of diamond, cubic boron nitride, corundum and the like, and to a metallic tool, in particular brush tools, produced by this method.

Bei Werkzeugen zum Entgraten und bei solchen zum Honen ist es bekannt, entsprechende Schleifsteine in Form von Sinterkörpern aus Schleifmittelteilchen und einem Bindemittel zu verwenden. Diese gesinterten Schleifsteine können an beliebig geformten Haltern befestigt und für das Entgraten bzw. Honen beliebiger Bohrungen und dgl. verwendet werden.In the case of tools for deburring and those for honing, it is known to use corresponding grindstones in the form of sintered bodies made of abrasive particles and a binder. These sintered grindstones can be fastened to holders of any shape and used for deburring or honing any holes and the like.

Es hat sich gezeigt, daß insbesondere für das Entgraten von Bohrungsrändern an den Enden von Bohrungen, innerhalb an Bohrungsmündungen und 'dgl. Bürstenwerkzeuge von Vorteil sind, insbesondere dann, wenn sie mit Schleifmittelteilchen besetzt sind. Aus der DE-PS 25 18 246 ist ein Bürstenwerkzeug bekannt, bei dem die Borsten aus Kunststoff sind und an ihren Enden mit einer kugelförmigen Kappe versehen sind. Diese Kugelkappe besteht aus Schleifmittelteilchen, die in einem Bindemittel gebunden sind, welches Bindemittel gleichzeitig dazu dient, die Kugelkappe am Borstenende fest zu halten.It has been shown that, in particular for deburring the edges of bores at the ends of bores, within bore mouths and the like. Brush tools are advantageous, especially if they are coated with abrasive particles. From DE-PS 25 18 246 a brush tool is known in which the bristles are made of plastic and are provided at their ends with a spherical cap. This ball cap consists of abrasive particles that are bound in a binder, which binder also serves to hold the ball cap firmly at the bristle end.

Nachteilig hieran ist, daß dieses Bürstenwerkzeug relativ weich ist und daß die mit den Schleifmittelteilchen versehene Kugelkappe relativ groß ist und damit ebenfalls zur Instabilität bzw. leichten Verknickbarkeit der einzelnen Borsten bzw. der Bürste insgesamt beiträgt. Da die Kugelkappen relativ groß sind, ist die Anzahl der Borsten am Bürstenteil des Werkzeuges relativ gering. Es können also keine üblichen Bürsten Verwendung finden, sondern es müssen Sonderanfertigungen vorliegen.The disadvantage of this is that this brush tool is relatively soft and that the spherical cap provided with the abrasive particles is relatively large and thus also contributes to the instability or easy buckling of the individual bristles or the brush as a whole. Since the ball caps are relatively large, the number of bristles on the brush part of the tool is relatively small. It is therefore not possible to use conventional brushes, but special designs must be available.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zum Besetzen von metallischen Werkzeugen mit Schleifmittelteilchen zu schaffen, das sowohl zum Besetzen von großflächigen Oberflächen an metallischen Werkzeugen als auch zum Besetzen der Borstenenden üblicher metallischer Bürstenwerkzeuge gleichermaßen einsetzbar ist. Außerdem soll ein nach diesem Verfahren hergestelltes metallisches Werkzeug, insbesondere Bürstenwerkzeug geschaffen werden.The object of the present invention is to provide a method for filling metallic tools with abrasive particles, which can be used both for filling large surfaces on metallic tools and for filling the bristle ends of conventional metallic brush tools. In addition, a metallic tool, in particular a brush tool, is to be created using this method.

Diese Aufgabe wird bei einem Verfahren der genannten Art durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale und bei einem Werkzeug der genannten Art durch die im Kennzeichen des Anspruchs 13 angebenen Merkmale gelöst.This object is achieved in a method of the type mentioned by the features specified in the characterizing part of claim 1 and in a tool of the type mentioned by the features specified in the characterizing part of claim 13.

Mit dem erfindungsgemäßen Verfahren ist es möglich, metallische Werkzeuge mit Schleifmittelteilchen, wie bspw. aus Diamant, kubischem Bornitrid, Korund oder dgl. derart zu besetzen, daß sie in einem Hartmetall eines Trägermaterials an den betreffenden Bereichen des metallischen Werkzeuges festgehalten sind, wobei sie in dem Trägermaterial derart teilweise eingebettet sind, daß sie zu einem Teil aus dem Trägermaterial herausragen und so als Schleifmittel dienen können. Derartige mit Schleifmittelteilchen besetzte metallische Werkzeuge haben eine sehr hohe Standzeit, die wesentlich über denen der bekannten Bürstenwerkzeuge liegt, da das Halten der Schleifmittelteilchen hier nicht durch Binde-und sonstige Klebemittel erfolgt, sondern die Schleifmittelteilchen in einem galvanisch aufgebrachten Trägermaterial eingeschlossen sind. Außerdem ist hierbei gewährleistet, daß stets eine ausreichende Menge und eine ausreichend große Oberfläche und Kanten der Schleifmittelteilchen aus dem metallischen Trägermaterial herausragen. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß bei Bürstenwerkzeugen die einzelnen Borstenenden mit relativ kleinen Kappen aus dem im Trägermaterial eingebetteten Schleifmittelteilchen versehen werden können.With the method according to the invention, it is possible to fill metallic tools with abrasive particles such as, for example, diamond, cubic boron nitride, corundum or the like in such a way that they are held in a hard metal of a carrier material at the relevant areas of the metallic tool, wherein they are held in the carrier material are partially embedded such that some of them protrude from the backing material and can thus serve as abrasives. Metallic tools of this type, coated with abrasive particles, have a very long service life, which is considerably longer than that of the known brush tools, since the abrasive particles are not held here by binding agents and other adhesives, but rather the abrasive particles are enclosed in a galvanically applied carrier material. This also ensures that a sufficient quantity and a sufficiently large surface area and edges of the abrasive particles always protrude from the metallic carrier material. Another advantage of the method according to the invention is that in the case of brush tools, the individual bristle ends can be provided with relatively small caps made of the abrasive particles embedded in the carrier material.

Bei dem Besetzen von metallischen Bürstenwerkzeugen bzw. von deren Borstenenden ist es zweckmäßig, denjenigen Teil des Bürstenwerkzeuges, der die Bürste aufweist, vollständig mit einem nichtleitenden Material, wie bspw. einem Lack, oder einem Wachs oder auch mit Gips auszufüllen und zu umhüllen, und dann in einem zweiten Arbeitsgang die Borstenenden in entsprechender Länge, von bspw. etwa 1 bis 2 mm wieder freizulegen, was bspw. mit Hilfe einer Schleifbürste erfolgen kann. Dies ist ein sehr einfacher Weg, die Bürste des Bürstenwerkzeuges so abzudecken, daß nur die Borstenenden, die besetzt werden sollen, freiliegen.When filling metallic brush tools or their bristle ends, it is expedient to completely cover that part of the brush tool which has the brush with a non-conductive material, such as, for example, a lacquer, or a wax or with plaster to fill and to cover, and then in a second operation to expose the bristle ends in the appropriate length, for example about 1 to 2 mm, which can be done with the help of a sanding brush. This is a very simple way to cover the brush of the brush tool so that only the bristle ends that are to be occupied are exposed.

In vorteilhafter Weise ist das nichtleitende Material derart ausgebildet, daß es in einem bestimmten Umgebungstemperaturbereich erstarrt ist, während es in einem vorzugsweise erheblich darüber liegenden Temperaturbereich bspw. zähflüssig ist. Dadurch kann das Abdecken in besonders einfacher Weise durch mehrmaliges Eintauchen und Herausnehmen und zwischenzeitliches Erstarren des Materials erfolgen. Das Entfernen der Abdeckung erfolgt am Schluß dann dadurch, daß das Werkzeug auf die betreffende Temperatur erwärmt wird, so daß das nunmehr flüssige Material zwischen den Borsten bzw. aus der Bürste heraustropfen kann.The non-conductive material is advantageously designed such that it solidifies in a certain ambient temperature range, while it is viscous, for example, in a temperature range which is preferably considerably higher. As a result, the covering can be carried out in a particularly simple manner by repeatedly immersing and removing and solidifying the material in the meantime. The cover is then removed at the end by heating the tool to the relevant temperature so that the now liquid material can drip out between the bristles or out of the brush.

Innerhalb des Trägermaterials 21 ist also ebenfalls eine Vielzahl von Schleifmittelteilchen 22 eingebettet und nur ein Teil der Schleifmittelteilchen 22 ragt aus dem Trägermaterial 21 heraus. Die vollständig eingebetteten Teilchen 22 kommen erst bei Abnutzung der Kappe 19 während der betreffenden Bearbeitung hervor und zur Wirkung. Die Korngröße der Schleifmittelteilchen bzw. der Diamantpartikel 22 kann unterschiedlich gewählt werden, und zwar je nach Anwendungs- . gebiet und zu bearbeitendes Material.As can be seen in FIG. 3, each free end 18 of a bristle 12 is provided with a cap 19 which is approximately two to three times the thickness of the metallic bristle 12. The cap 19 consists of nickel as the carrier material 21, in which diamond particles 22 are partially or completely embedded as abrasive particles such that they protrude from the carrier material 21 by about 1/2 to 1/3 of their size. A multiplicity of abrasive particles 22 are also embedded within the carrier material 21 and only a part of the abrasive particles 22 protrude from the carrier material 21. The fully embedded particles 22 only emerge and become effective when the cap 19 wears out during the processing in question. The grain size of the abrasive particles or Diamond particles 22 can be selected differently, depending on the application. area and material to be processed.

Das in Fig. 2 dargestellte Werkzeug 26 dient ebenfalls zum Entgraten und ist um seine Achse 27 herum mit federnden Stäben 28 versehen, die über den Umfang verteilt angeordnet sind und die an ihren Enden durch je eine Hülse 29, 29' fixiert bzw. festgehalten sind. Die Stäbe 28 verlaufen von einer Hülse 29 zur anderen Hülse 29' bauchig, d.h., sie verändern ihren Abstand zur Achse 27 stetig. Außerdem verlaufen sie im Bezug auf die Längsrichtung der Achse 27 etwas verdrillt.The tool 26 shown in Fig. 2 is also used for deburring and is provided around its axis 27 with resilient rods 28 which are arranged distributed over the circumference and which are fixed or held at their ends by a sleeve 29, 29 ' . The rods 28 run from one sleeve 29 to the other sleeve 29 ', i.e. they change their distance from the axis 27 continuously. In addition, they run somewhat twisted with respect to the longitudinal direction of the axis 27.

Innerhalb des mit A angebenen Bereiches sind die Stäbe 28 mit Diamantpartikeln als Schleifmittelteilchen 22' besetzt, die auch hier in Nickel als Trägermaterial 21' teilweise derart eingebettet sind, daß sie zu etwa 1/2 bis 1/3 ihrer Größe aus dem Trägermaterial 21' herausragen.Within the area indicated by A, the rods 28 are covered with diamond particles as abrasive particles 22 ', which are also partially embedded in nickel as the carrier material 21' in such a way that they are approximately 1/2 to 1/3 of their size from the carrier material 21 ' stick out.

Es versteht sich, daß bei beiden Werkzeugen 11 und 26 das Trägermaterial, das hier Nickel ist, auch durch ein anderes Hartmetall, wie Chrom, oder auch durch ein weicheres Metall, wie Kupfer, Zink oder dgl. ersetzt werden kann. Außerdem können auch die Schleifmittelteilchen 22, 22', die hier Diamantpartikel sind, durch andere Schleifmittel, wie kubisches Bornitrid, Korund, Saphir, Rubin oder dgl. ersetzt werden. Es versteht sich ferner, daß statt des Werkzeuges 26 der Fig. 2 auch andere derartige mit großflächiger Schleiffläche versehene Werkzeuge mit entsprechenden im Trägermaterial eingebetteten Schleifmittelteilchen besetzt werden können.It is understood that in both tools 11 and 26, the carrier material, which is nickel, also by another hard metal, such as chromium, or can also be replaced by a softer metal, such as copper, zinc or the like. In addition, the abrasive particles 22, 22 ', which are diamond particles here, can also be replaced by other abrasives, such as cubic boron nitride, corundum, sapphire, ruby or the like. It is further understood that instead of the tool 26 of FIG. 2, other such tools provided with a large-area grinding surface can also be filled with corresponding abrasive particles embedded in the carrier material.

Das Besetzen der metallischen Borsten 12 des Bürstenwerkzeugs 11 mit den Kappen 19 geht folgendermaßen vor sich:

  • Zunächst wird das Bürstenwerkzeug 11 zumindest mit demjenigen Teil, der die Bürste bzw. die Borsten 12 enthält, vollständig mit einem nichtleitenden Material abgedeckt. Dieses Abdecken erfolgt dadurch, daß ein nichtleitendes Material verwendet wird, das in warmem Zustand flüssig, bspw. zähflüssig ist und in einem bestimmten Umgebungstemperaturbereich erstarrt. Bspw. ist das betreffende Material, ein Wachs, bei etwa 40°C erstarrt, während es oberhalb dieser Temperatur bei bspw. etwa 200°C eine flüssige bis teigige Breimasse ist. In dieses erwärmte bzw. erhitzte flüssige Material wird der betreffende Bürstenwerkzeugteil vollständig eingetaucht, dann herausgezogen und gedreht, wobei das anhaftende nichtleitende Material erstarrt. Dieser Vorgang, d.h. Eintauchen, Herausziehen und Drehen, wird so lange wiederholt, bis der Bürstenteil bzw. der mit den Borsten 12 versehene Teil des Werkzeuges 11 von dem nichtleitenden Material vollständig abgedeckt ist.
  • Es versteht sich, daß als nichtleitendes Material auch ein entsprechender Lack oder auch Gips Verwendung finden kann.
  • Daraufhin wird die Bürste auf bspw. eine Drehbank gespannt und mit einer normalen Schleifbürste außenumfangsseitig abgeschliffen, so daß die freien Enden der Borsten 12 auf etwa 1 bis 2 mm Länge freigelegt werden. Diese freigelegten Enden bzw. Spitzen 18 der Borsten 12 werden dann mit den Kappen 19 galvanisch besetzt.
The filling of the metallic bristles 12 of the brush tool 11 with the caps 19 proceeds as follows:
  • First, the brush tool 11 is completely covered with a non-conductive material, at least with the part that contains the brush or bristles 12. This covering takes place in that a non-conductive material is used which, when warm, is liquid, for example viscous, and solidifies in a certain ambient temperature range. E.g. is the material in question, a wax, at around 40 ° C solidifies, while above this temperature it is a liquid to pasty paste, for example at about 200 ° C. The brush tool part in question is completely immersed in this heated or heated liquid material, then pulled out and rotated, the adhering non-conductive material solidifying. This process, ie immersion, pulling out and turning, is repeated until the brush part or the part of the tool 11 provided with the bristles 12 is completely covered by the non-conductive material.
  • It goes without saying that a corresponding lacquer or gypsum can also be used as the non-conductive material.
  • The brush is then clamped on a lathe, for example, and ground on the outer circumference with a normal grinding brush, so that the free ends of the bristles 12 are exposed to a length of about 1 to 2 mm. These exposed ends or tips 18 of the bristles 12 are then galvanically covered with the caps 19.

Die freigelegten Enden 18 der Borsten 12 werden zur Vorbereitung des galvanischen Aufbringens der Kappen 19 in ein Ätzbad gelegt, so daß die Borstenenden 17 angeätzt werden und damit chemisch gereinigt werden.The exposed ends 18 of the bristles 12 are placed in an etching bath in preparation for the galvanic application of the caps 19, so that the bristle ends 17 are etched and thus chemically cleaned.

Das metallische Bürstenwerkzeug 11, das also zum größten Teil abgedeckt ist und bei dem lediglich die oben erwähnten Borstenenden 18 etwa 1 bis 2 mm lang freiliegen, wird nun in ein Galvanikbad getaucht und stellt so die eine Elektrode dar. Das Galvanikbad kann elektrolytisch oder stromlos betrieben werden. Im Galvanikbad wird ein Trägermaterial 21, beim Ausführungsbeispiel Nickel, von der anderen Elektrode auf die freiliegenden Enden 18 der Borsten 12 abgeschieden und galvanisch aufgebracht. Dabei werden gleichzeitig mit dem galvanischen Aufbringen von Nickel 21 auf die Borstenenden 18 die Diamantpartikel 22 mit zu den Borstenenden 18 gebracht und in das Trägermaterial eingebettet.The metallic brush tool 11, which is therefore largely covered and in which only the above-mentioned bristle ends 18 are exposed for about 1 to 2 mm, is now immersed in an electroplating bath and thus represents one electrode. The electroplating bath can be operated electrolytically or without current will. In the electroplating bath, a carrier material 21, in the exemplary embodiment nickel, is deposited from the other electrode onto the exposed ends 18 of the bristles 12 and applied galvanically. At the same time as the electrolytic application of nickel 21 to the bristle ends 18, the diamond particles 22 are brought to the bristle ends 18 and embedded in the carrier material.

Bei dem Bürstenwerkzeug 11 gemäß den Fig. 1 und 3, das mit Diamantpartikel 22 als Schleifmittelteilchen besetzt werden soll, wird das Bürstenwerkzeug 11 auf einen bspw. rinnenförmigen Träger im Galvanikbad gelegt, und zwar derart, daß das Bürstenwerkzeug 11 vollständig untergetaucht ist. Daraufhin wird das Diamantpulver als breiige Substanz auf den obenliegenden Bereich der Bürste des Werkzeuges 11 gebracht. Daraufhin wird das Galvanikbad aktiviert, so daß sich Nickel als Trägermaterial 21 an den Enden 18 der Borsten 12 abscheidet und dabei die Partikel des Diamantpulvers miteinbettet. Ist dies bis zu einem gewissen Grade erfolgt, so wird das Bürstenwerkzeug 11 gedreht, worauf der andere gegenüberliegende Bereich der Bürste mit dem Diamantpulver belegt und dann das Galvanikbad wieder aktiviert wird, so daß auch hier die Diamantpartikel bis zu einem gewissen _Grade mit dem galvanischen Aufbringen des Trägermaterials an die Borstenenden 18 in das Trägermaterial eingebettet werden.In the brush tool 11 according to FIGS. 1 and 3, which is to be filled with diamond particles 22 as abrasive particles, the brushing Tool 11 placed on a channel-shaped support in the electroplating bath, for example, in such a way that the brush tool 11 is completely immersed. The diamond powder is then brought as a pulpy substance onto the upper area of the brush of the tool 11. The electroplating bath is then activated, so that nickel is deposited as the carrier material 21 at the ends 18 of the bristles 12 and the particles of the diamond powder are embedded in the process. If this has occurred to a certain extent, the brush tool 11 is rotated, whereupon the other opposite area of the brush is coated with the diamond powder and the electroplating bath is then reactivated, so that the diamond particles are also galvanically applied to a certain degree of the carrier material at the bristle ends 18 are embedded in the carrier material.

In diesem Zustand haften die Diamantpartikel lediglich unvollkommen an den Borstenenden 18, da diese bis jetzt nur mit einer relativ geringen Schichtdicke am Trägermaterial 21 eingebettet sind. Das weitere Einbetten der Diamantpartikel erfolgt beim Ausführungsbeispiel in einem zweiten Galvanikbad, das ebenfalls elektrolytisch oder stromlos betrieben werden kann. In diesem Bad erfolgt nun ein Einbetten der Diamantpartikel in der Weise, daß die inneren Schleifmittelteilchen vollständig im Trägermaterial 21 eingebettet werden, während die äußeren Diamantpartikel nur soweit eingebettet werden, daß sie höchstens zu etwa 1/4 bis 1/3 ihrer Größe aus dem Trägermaterial 21 herausragen. Die Zeit, die für dieses Einbetten benötigt wird, hängt von den Daten des Galvanikbades ab. Am Ende dieses Prozesses sind die Diamantpartikel innerhalb des Trägermaterials 21 derart verankert, daß sie als Schleifmittel Verwendung finden können und dabei eine sehr hohe Standzeit besitzen. Eine gewisse Abnutzung wird dadurch aufgefangen, daß die Kappe 19 eine bestimmte Größe aufweist und innerhalb der Kappe 19 weitere Diamantpartikel angeordnet sind, die während des Abnutzungsvorganges dann freigelegt werden und zur Wirkung kommen.In this state, the diamond particles only adhere imperfectly to the bristle ends 18, since until now these have only been embedded on the carrier material 21 with a relatively small layer thickness. The further embedding of the diamond In the exemplary embodiment, particles take place in a second electroplating bath, which can also be operated electrolytically or without current. The diamond particles are now embedded in this bath in such a way that the inner abrasive particles are completely embedded in the carrier material 21, while the outer diamond particles are only embedded to such an extent that they are at most approximately 1/4 to 1/3 of their size from the carrier material 21 protrude. The time required for this embedding depends on the data from the electroplating bath. At the end of this process, the diamond particles are anchored within the carrier material 21 in such a way that they can be used as abrasives and have a very long service life. A certain amount of wear and tear is absorbed by the fact that the cap 19 has a certain size and further diamond particles are arranged inside the cap 19, which are then exposed during the wear process and come into effect.

Es ist auch möglich, die freiliegenden Enden 18 der Borsten 12 nach dem Anätzen in einem besonderen Galvanobad vorab mit Trägermaterial 21 in Form einer dünnen Schicht zu versehen, also anzunickeln.It is also possible to cover the exposed ends 18 of the bristles 12 in a special electroplating bath beforehand with carrier material 21 to be provided in the form of a thin layer, i.e. to be nickel-coated.

Es ist ferner möglich, das vollständige Einbetten, nicht wie oben beschrieben in einem besonderen Galvanobad, sondern in dem Bad vorzunehmen, wo auch die Schleifmittelteilchen eingebracht werden. Werden weniger teuere Schleifmittelteilchen als Diamant verwendet, so ist es auch möglich, die Schleifmittelteilchen im Galvanobad als Sumpf vorzusehen und das betreffende Ende des Bürstenwerkzeuges 11 während des metallischen Abscheidungsvorganges darin eingetaucht zu lassen, so daß ein Verdrehen des Bürstenwerkzeuges 11 während dieses galvanischen Vorganges nicht notwendig ist.It is also possible to carry out the complete embedding, not as described above in a special electroplating bath, but in the bath where the abrasive particles are also introduced. If less expensive abrasive particles than diamond are used, it is also possible to provide the abrasive particles in the plating bath as a sump and to leave the relevant end of the brush tool 11 immersed therein during the metallic deposition process, so that twisting of the brush tool 11 during this galvanic process is not necessary is.

Sind die freien Enden 18 der Borsten 12 jeweils mit einer Kappe 19 versehen, so muß das Abdeckmaterial in Form des nichtleitenden Wachses bzw. sonstigen Materials wieder entfernt werden. Dazu wird der betreffende Teil des Bürstenwerkzeuges 11 auf die entsprechende Temperatur erwärmt, so daß das dann flüssige Wachs wieder aus der Bürste 11 heraustropfen kann. Dadurch ist in einfacher Weise das nichtleitende Abdeckmaterial wieder entfernt.If the free ends 18 of the bristles 12 are each provided with a cap 19, the covering material in the form of the non-conductive wax or other material must be removed again. For this purpose, the relevant part of the brush tool 11 is heated to the appropriate temperature, so that the liquid wax can then drip out of the brush 11 again. There by the non-conductive covering material is removed again in a simple manner.

Das Besetzen des Werkzeuges 26 nach Fig. 2 mit Schleifmittelteilchen 22', die in einem Trägermaterial eingebettet sind, erfolgt in ähnlicher Weise. Gemäß Fig. 2 soll nur der Bereich A des Werkzeuges 26 mit Schleifmittelteilchen besetzt werden. Deshalb werden die anderen Bereiche mit bspw. Isolierband umwickelt und dadurch abgedeckt. Danach wird das Verfahren in gleicher Weise wie oben beschrieben durchgeführt, d.h., die freiliegenden Werkzeugbereiche werden angeätzt, ggf. angenickelt und dann im Galvanobad mit dem Trägermaterial und den Schleifmittelteilchen versehen. Am Ende müssen die Isolierbänder und dgl. wieder entfernt werden. Bei diesem Vorgang wird zwar der freiliegende Bereich der Werkzeugachse 27 unnötigerweise ebenfalls mitbesetzt, jedoch ist hier der Vorgang des Abdeckens der anderen Bereiche sehr einfach. Will man hier nur die betreffenden Bereiche der Stäbe 28 des Werkzeuges 26 mit den Schleifmittelteilchen 22' besetzen, so ist es auch möglich, diese einzeln in das Galvanikbad zu tauchen.The tool 26 according to FIG. 2 is filled with abrasive particles 22 ′ which are embedded in a carrier material in a similar way. 2, only area A of tool 26 is to be occupied with abrasive particles. Therefore, the other areas are wrapped with, for example, insulating tape and thereby covered. The method is then carried out in the same way as described above, i.e. the exposed tool areas are etched, possibly nickel-plated and then provided with the backing material and the abrasive particles in the electroplating bath. At the end, the insulating tapes and the like must be removed again. In this process, the exposed area of the tool axis 27 is also unnecessarily also occupied, but here the process of covering the other areas is very simple. If you only want to fill the relevant areas of the rods 28 of the tool 26 with the abrasive particles 22 ', it is also possible to immerse them individually in the electroplating bath.
