Definitions
- the invention relates to the use of a grinding or the like tool made of a ceramic material and a method for producing grinding or the like tools coated with extremely hard abrasive grains.
- grinding and “grinding tool” used here and below are to be understood in the broadest sense, i.e. that in particular also “honing”, “hard cockroaches”, “scraping”, “honing” and “dressing” including the tools used for this are to be understood.
- extreme hard abrasive grains which should be understood to mean diamond, CBN, tungsten carbide and the like grains as used in abrasive, i.e. no uniformly directed cutting edges of tools of the type mentioned are known.
- the invention has for its object ways and means to find, with which tools of the type mentioned are cheaper to grind than before, in particular the grinding tool used for this should be simple and cheap to manufacture.
- the solution should also be applicable to other grinding and similar tools that are used in fine gear machining.
- the problem is solved primarily in the use of a known ceramic grinding tool as the base body for a grinding tool coated with extremely hard abrasive grains.
- a plate-shaped grinding wheel 1 made of ceramic material is covered with extremely hard abrasive grains 3 at least on one end face 2 thereof.
- the end face 2 to be covered is coated with an adhesive 4 and the abrasive grains 3 are applied immediately thereafter. This can be done by sprinkling or by applying with a brush.
- the abrasive grains 3 are pressed against the grinding wheel. The abrasive grains 3 slide into the pores 5 of the ceramic material 6 (FIG. 2), into which the adhesive 4 has already “sucked in”.
- the grinding grains 3 can be pressed in with a correspondingly shaped pressing tool, not shown, but also by brushing in with a simple tool, for example a spatula, in an extreme case even with the finger.
- Dan adhesive 4 is then allowed to harden according to the manufacturer's instructions. In the case of an adhesive based on epoxy resin, this can be, for example, 2 hours at about 150 ° C.
- the grinding wheel according to Fig. 1 is briefly pulled off in the area of its outer contour, e.g. with a single-grain diamond dresser. Each time you pull off, new abrasive grains are exposed on the occupied end face 2, which then act as "cutting".
- a grinding wheel 1 coated with diamond grains as described above can be used both for grinding gear-like tools coated with CBN grains in accordance with DE-OS 33 36 593 and for grinding hardened workpiece gear wheels in particular.
- a grinding wheel coated with CBN grains is usually used to grind hardened workpiece gears.
- a gear-shaped tool 7 (FIG. 3) can be coated in the same way on its tooth flanks with extremely hard abrasive grains. To do this, it only needs to be precisely aligned and ground beforehand. To press in the abrasive grains 3, the tool 7 is unrolled with a master wheel 8, since the abrasive grains 3 then only protrude very little and evenly from the previously ground tooth flanks.
- a grinding wheel 10 with a circular cross-section (cylindrical, conical, spherical, etc.), which is effective on its peripheral surface 12, as shown in FIG. 4, can be coated with extremely hard abrasive grains in basically the same way. To do this, it is precisely aligned and subtracted beforehand. To press in the abrasive grains 3, the grinding wheel 10 is allowed to roll on a correspondingly shaped counter surface or such a counter surface is guided along the rolling grinding wheel. If the grinding wheel 10 is also to be covered on one or both end faces 11, the same procedure can be followed as described above in connection with the plate-shaped grinding wheel 1.

Abstract
Description
Die Erfindung betrifft die Verwendung eines Schleif- od. dgl. Werkzeugs aus einem Keramikmaterial sowie Verfahren zum Herstellen von mit extrem harten Schleifkörnern beschichteten Schleif- od. dgl. Werkzeugen. Es wird an dieser Stelle ausdrücklich darauf hingewiesen, daß die hier und im folgenden verwendeten Begriffe "Schleifen" und "Schleifwerkzeug" im weitesten Sinne zu verstehen sind, d.h. daß insbesondere auch "Honen", "Hartschaben", "Schabschleifen", "Abziehen" und "Abrichten" einschließlich der dafür verwendeten Werkzeuge darunter zu verstehen sind. Das gilt sinngemäß auch für den Begriff "extrem harte Schleifkörner", worunter Diamant-, CBN-, Wolframkarbid- und dgl. Körner verstanden werden sollen, wie sie bei abrasiven, d.h. keine einheitlich gerichteten Schneidkanten aufweisenden Werkzeugen der genannten Art bekannt sind.The invention relates to the use of a grinding or the like tool made of a ceramic material and a method for producing grinding or the like tools coated with extremely hard abrasive grains. At this point, it is expressly pointed out that the terms "grinding" and "grinding tool" used here and below are to be understood in the broadest sense, i.e. that in particular also "honing", "hard cockroaches", "scraping", "honing" and "dressing" including the tools used for this are to be understood. This also applies analogously to the term "extremely hard abrasive grains", which should be understood to mean diamond, CBN, tungsten carbide and the like grains as used in abrasive, i.e. no uniformly directed cutting edges of tools of the type mentioned are known.
Aus der DE-OS 33 36 593 ist ein mit CBN-Körnern beschichtetes Werkzeug zum Feinbearbeiten der Zahnflanken von Werkstücke-Zahnrädern bekannt, bei dem die Zahnflanken überschliffen sind. Das Überschleifen der Zahnflanken ist enorm zeitaufwendig und die dafür verwendeten, mit Diamantkörnern beschichteten Werkzeuge sind sehr teuer in der Anschaffung.From DE-OS 33 36 593 a tool coated with CBN grains for fine machining of the tooth flanks of work piece gears is known, in which the tooth flanks are ground. Grinding the tooth flanks is extremely time-consuming and the tools used for this, coated with diamond grains, are very expensive to purchase.
Der Erfindung liegt die Aufgabe zugrunde, Mittel und Wege zu finden, mit denen Werkzeuge der genannten Art kostengünstiger zu Schleifen sind als bisher, wobei insbesondere das dafür verwendete Schleifwerkzeug einfach und billig in der Anfertigung sein soll. Außerdem soll die Lösung auch bei anderen Schleif- und dgl. Werkzeuge anwendbar sein, die in der Zahnradfeinbearbeitung eingesetzt werden.The invention has for its object ways and means to find, with which tools of the type mentioned are cheaper to grind than before, in particular the grinding tool used for this should be simple and cheap to manufacture. In addition, the solution should also be applicable to other grinding and similar tools that are used in fine gear machining.
Gemäß dem Patentanspruch 1 besteht die Lösung der Aufgabe primär in der Verwendung eines bekannten Keramik-Schleifwerkzeuges als Grundkörper für ein mit extrem harten Schleifkörnern beschichtetes Schleifwerkzeug.According to claim 1, the problem is solved primarily in the use of a known ceramic grinding tool as the base body for a grinding tool coated with extremely hard abrasive grains.
In den Ansprüchen 2 und 3 werden Verfahren aufgezeigt zum Herstellen von scheiben- bzw. zahnrad-, zahnstangen- oder schneckenförmigen Werkzeugen, wie sie insbesondere zum Feinbearbeiten von Zahnrädern und dgl. Werkstücken Verwendung finden. Dabei können die Schleifkörner von Hand mit einem einfachen Werkzeug, z.B. einem Spatel od. dgl. eingedrückt werden, oder aber mit den in den Ansprüchen 4, 5 und 6 angegebenen Hilfsmitteln.In
Die Erfindung wird nachstehend anhand von drei Ausführungsbeispielen beschrieben, die in 4 Figuren dargestellt sind. Es zeigen
- Fig. 1 eine tellerförmige Schleifscheibe im Schnitt,
- Fig. 2 einen vergrößert dargestellten Ausschnitt aus einem gemäß der Erfindung hergestellten Werkzeug,
- Fig. 3 ein zahnradförmiges Schleif- od. dgl. Werkzeug, und

Eine tellerförmige Schleifscheibe 1 (Fig. 1) aus Keramik-Material ist zumindest auf ihrer einen Stirnseite 2 mit extrem harten Schleifkörnern 3 belegt. Dazu wird die zu belegende Stirnseite 2 mit einem Klebstoff 4 eingestrichen und unmittelbar danach werden die Schleifkörner 3 aufgebracht. Das kann durch Aufstreuen erfolgen oder durch Auftragen mit einem Pinsel. Noch ehe der Klebstoff 4 anfängt hart zu werden, werden die Schleifkörner 3 gegen die Schleifscheibe gedrückt. Dabei schieben sich die Schleifkörner 3 in die Poren 5 des Keramik-Materials 6 (Fig. 2), in die sich der Klebstoff 4 schon vorher "eingesaugt" hat. Das Eindrücken der Schleifkörner 3 kann mit einem entsprechend geformten, nicht dargestellten Drückwerkzeug erfolgen, aber auch durch Einstreichen mit einem einfachen Werkzeug, z.B. einem Spatel, im Extremfall sogar mit dem Finger. Anschließend läßt man dan Klebstoff 4 entsprechend den Vorschriften des Herstellers aushärten. Bei einem Kleber auf Epoxydharz-Basis kann das z.B. 2 Stunden bei etwa 150oC sein.A plate-shaped grinding wheel 1 (FIG. 1) made of ceramic material is covered with extremely hard
Die Schleifscheibe nach Fig. 1 wird, um mit ihr arbeiten zu können, im Bereich ihrer Außenkontur kurz abgezogen, z.B. mit einem Einkorn-Diamant-Abrichter. Dabei werden bei jedem Abziehen neue Schleifkörner an der belegten Stirnseite 2 freigelegt, die dann als "Schneiden" fungieren.In order to be able to work with it, the grinding wheel according to Fig. 1 is briefly pulled off in the area of its outer contour, e.g. with a single-grain diamond dresser. Each time you pull off, new abrasive grains are exposed on the occupied
Eine wie vorstehend beschrieben mit Diamantkörnern beschichtete Schleifscheibe 1 kann sowohl zum Schleifen von mit CBN-Körnern beschichteten zahnradartigen Werkzeugen gemäß der DE-OS 33 36 593 verwendet werden als auch zum Schleifen von insbesondere gehärteten Werkstück-Zahnrädern. Eine entsprechend mit CBN-Körnern beschichtete Schleifscheibe wird i.d.R. zum Schleifen von gehärteten Werkstück-Zahnrädern benützt.A grinding wheel 1 coated with diamond grains as described above can be used both for grinding gear-like tools coated with CBN grains in accordance with DE-OS 33 36 593 and for grinding hardened workpiece gear wheels in particular. A grinding wheel coated with CBN grains is usually used to grind hardened workpiece gears.
Ein zahnradförmiges Werkzeug 7 (Fig. 3) kann in im Prinzip gleicher Weise auf seinen Zahnflanken mit extrem harten Schleifkörnern belegt werden. Dazu muß es nur vorher exakt ausgerichtet und genau geschliffen worden sein. Zum Eindrücken der Schleifkörner 3 läßt man das Werkzeug 7 mit einem Meisterrad 8 abrollen, da dann die Schleifkörner 3 nur noch ganz wenig und gleichmäßig aus den vorher geschliffenen Zahnflanken vorstehen.A gear-shaped tool 7 (FIG. 3) can be coated in the same way on its tooth flanks with extremely hard abrasive grains. To do this, it only needs to be precisely aligned and ground beforehand. To press in the
