Description

Die Erfindung bezieht sich auf ein Abrichtwerkzeug.The invention relates to a dressing tool.

Die Hauptfunktion von Abrichtwerkzeugen bei der Bearbeitung von Schleifscheibenarbeitsflächen bestehen zum einen im Entfernen von stumpfgewordenen Schleifkörnern und von Metallpartikeln, die die Schleifscheibenarbeitsfläche während des Einsatzes zusetzen, und andererseits in der Wiederherstellung der korrekten geometrischen Form des Schleifkörpers. Dabei ist es seit langem bekannt, Diamantwerkzeuge als Abrichtwerkzeuge einzusetzen. So gibt es Diamant-Einzel-und Vielkornabrichter, Diamant-Abrichtblöcke und Diamant-Abrichtrollen. Bei der Verwendung eines Abrichtblockes kann dieser unter der Schleifscheibe durchlaufen, wobei der Abtrag in mehreren Durchgängen mit geringer Tiefenzustellung erfolgen kann. Diamant-Abrichtrollen führen beim Abrichten von Schleifscheiben eine Drehbewegung und vorzugsweise eine Relativbewegung zu der sich gleichfalls drehenden Schleifscheibe aus, wobei die Drehbewegung vorzugsweise über einen getrennten Antrieb in beiden Drehrichtungen erfolgen kann.The main function of dressing tools in the machining of grinding wheel work surfaces is on the one hand to remove blunt abrasive grains and metal particles that clog the grinding wheel work surface during use, and on the other hand to restore the correct geometric shape of the grinding wheel. It has long been known to use diamond tools as dressing tools. There are diamond single and multigrain dressers, diamond dressing blocks and diamond dressing rollers. If a dressing block is used, it can pass under the grinding wheel, whereby the removal can take place in several passes with little depth infeed. Diamond dressing rollers perform a rotational movement and preferably a relative movement to the grinding wheel, which is also rotating, when dressing grinding wheels, the rotating movement preferably being able to take place via a separate drive in both directions of rotation.

Bei der Herstellung von Diamantabrichtrollen kennt man das Positiv- und das Negativ-Verfahren. Dabei wird bei dem Positiv-Verfahren auf einem maßgenauen Grundkörper Diamantkorn aufgebracht und durch galvanischen Metallniederschlag gebunden. Mit diesem Verfahren sind Diamant-Abrichtrollen nur in begrenzter Genauigkeit herstellbar. Bei dem Negativ-Verfahren erzielt man eine bessere Formgenauigkeit. So werden in einem Formring, dessen Innenform genau der herzustellenden Abrichtrolle entspricht; Diamanten von Hand und mit galvanischem Metallniederschlag oder Sintermetall eingebracht und anschließend in verschiedenster Weise gebunden. Nach Entfernen des Formringes entsteht eine Abrichtrolle, deren Außenkonturen genau dem gewünschten Profil entsprechen.The positive and negative processes are known in the manufacture of diamond dressing rolls. In the positive process, diamond grain is applied to a dimensionally accurate base body and bound by means of galvanic metal precipitation. With this method, diamond dressing rolls can only be manufactured with limited accuracy. With the negative process, better shape accuracy is achieved. So are in a form ring, the inner shape of which corresponds exactly to the dressing roller to be produced; Diamonds introduced by hand and with galvanic metal deposit or sintered metal and then bound in various ways. After removing the form ring, a dressing roller is created, the outer contours of which correspond exactly to the desired profile.

Durch die Verwendung verschiedener Diamant-Korngrößen und Fertigungstechniken sowie unterschiedlicher metallischer oder plastischer Bindungen können verschiedenartige Ausführungen von Abrichtrollen hergestellt werden. Dabei sind bis auf wenige Ausnahmen die Diamantabrichtrollen nur mit einer einzigen Diamantkornschicht belegt, die die gesamte Oberfläche der Abrichtrolle bedeckt, also eine geschlossene Fläche bildet.Different types of dressing rollers can be produced by using different diamond grain sizes and manufacturing techniques as well as different metallic or plastic bonds. With a few exceptions, the diamond dressing rollers are only covered with a single diamond grain layer, which covers the entire surface of the dressing roller, i.e. forms a closed surface.

Es ist Aufgabe der vorliegenden Erfindung, ein Abrichtwerkzeug zur Verfügung zu stellen, das bei den bearbeiteten Schleifscheiben eine überaus hohe geometrische Genauigkeit und außerdem eine Schärfung sicherstellt, durch die Standzeiten der Schleifscheiben erhöht werden. Außerdem soll ein Abrichtwerkzeug geschaffen werden, dessen Zustellung in Bezug auf die zu bearbeitende Schleifscheibe im Vergleich zu den bekannten Abrichtwerkzeugen um ein Vielfaches erhöht wird, um die Abrichtzeit erheblich zu reduzieren.It is an object of the present invention to provide a dressing tool which ensures extremely high geometric accuracy and also a sharpening in the processed grinding wheels, by means of which the service lives of the grinding wheels are increased. In addition, a dressing tool is to be created, the infeed of which in relation to the grinding wheel to be machined is increased many times over in comparison to the known dressing tools in order to significantly reduce the dressing time.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Profil des Abrichtwerkzeugs von im Abstand zueinander angeordneten profilierten Platten aus hartem oder überhartem Material gebildet ist. Dabei ist vorzugsweise das harte oder überharte Material polykristalliner synthetischer Diamant oder kubisch kristallines Bornitrid oder Hartmetall z.B. in Form von Wolframverbindungen oder Titanverbindungen oder Keramik, wobei in Ausgestaltung der Erfindung die Platten aus einer kompakten Einheit des harten oder überharten Materials oder aus mit einer Beschichtung des Materials versehenem das Profil aufweisendem Grundkörper bestehen. Sofern beschichtete Grundkörper als profilierte Platten benutzt werden, sind bekannte Verfahren, wie z.B. elektrolytisches Auftragen oder Aufdampfen einsetzbar, die bei Diamant- oder Hartmetall- oder Keramikschneidstoffen Verwendung finden.The object is achieved in that the profile of the dressing tool is formed by spaced profiled plates made of hard or superhard material. It is preferably the hard one or superhard material polycrystalline synthetic diamond or cubic crystalline boron nitride or hard metal, for example in the form of tungsten compounds or titanium compounds or ceramics, wherein in one embodiment of the invention the plates consist of a compact unit of the hard or superhard material or of a base body provided with a coating of the material and having the profile consist. If coated base bodies are used as profiled plates, known methods, such as, for example, electrolytic application or vapor deposition, can be used, which are used for diamond or hard metal or ceramic cutting materials.

Ein erfindungsgemäßes Abrichtwerkzeug in Form einer Abrichtrolle zeichnet sich durch im Abstand zueinander auf der Umfangsfläche eines Schaftkörpers angeordnete Segmente z.B. in Form von Zähnen aus, auf deren Brustflächen die profilierten Platten aus hartem oder überhartem Material vorgesehen sind. Bevorzugt setzt sich das Profil der Abrichtrolle aus den Frontflächen der profilierten Platten aus hartem oder überhartem Material von vorzugsweise zwei Zähnen zusammen. Dies ist insbesondere dann von Vorteil, wenn sich eine Brustfläche eines Zahnes aus mehreren profilierten Platten aus synthetischem Diamant zusammensetzt, sofern diese nicht beliebig dimensioniert zur Verfügung stehen. Es werden dann die profilierten Platten von aufeinanderfolgenden Zähnen gegeneinander versetzt angeordnet, um eine Überlappung zu erzielen. Dadurch ergibt sich der Vorteil, daß beim Abrichten der Stoß von nebeneinanderliegenden Platten nicht bemerkbar wird. In weiterer Ausgestaltung der Erfindung sind vor den Brustflächen im Schaftkörper Spankammern angeordnet, um die beim Bearbeiten der Schleifscheibe anfallenden Metallpartikel und Schleifkörner aufnehmen zu können, da andernfalls aufwendige Einrichtungen zum Entfernen erforderlich wären.A dressing tool according to the invention in the form of a dressing roller is characterized by segments spaced apart on the circumferential surface of a shaft body, for example in the form of teeth, on the breast surfaces of which the profiled plates made of hard or superhard material are provided. The profile of the dressing roller is preferably composed of the front surfaces of the profiled plates made of hard or superhard material, preferably two teeth. This is particularly advantageous if a breast surface of a tooth is composed of several profiled plates made of synthetic diamond, provided that these are not available in any dimension. The profiled plates of successive teeth are then offset from one another in order to achieve an overlap. This has the advantage that the impact of adjacent plates is not noticeable when dressing. In further out Design of the invention, chip chambers are arranged in front of the chest surfaces in the shaft body in order to be able to accommodate the metal particles and abrasive grains that occur during machining of the grinding wheel, since otherwise complex devices would have to be removed.

Bei einem Abrichtwerkzeug in Form eines Abrichtblockes wird erfindungsgemäß vorgeschlagen, im Abstand zueinander und auf Vorsprünge angeordnete profilierte Platten aus hartem oder überhartem Material auf einem Grundkörper anzuordnen und die das Profil des Abrichtblockes bilden. Dabei wird vorzugsweise die Profilfläche von auf zumindest zwei Vorsprüngen angeordneten profilierten Platten aus hartem oder überhartem Material gebildet, sofern mehr als eine Platte die Frontfläche eines Vorsprunges bildet. Gleichzeitig wird vorgeschlagen, Spankammern vor den Vorsprüngen vorzusehen.In the case of a dressing tool in the form of a dressing block, it is proposed according to the invention to arrange profiled plates made of hard or superhard material on a base body at a distance from one another and on projections and which form the profile of the dressing block. The profile surface is preferably formed by profiled plates made of hard or superhard material arranged on at least two projections, provided that more than one plate forms the front surface of a projection. At the same time, it is proposed to provide chip chambers in front of the projections.

Um gewünschte Profile mit z.B. heutzutage erhältlichen polykristallinen synthetischen Diamantplättchen, die beispielsweise in Form von Kreisscheiben der Dicken von 1,5 oder 3,2 mm und mit einem Durchmesser von 13,7 mm erhältlich sind, zu erzielen, werden die Platten mittels Funkenerosion oder mittels eines Elektronen- oder Laser-Strahls oder eines heißen Sauerstoffstrahls oder durch Schleifen oder formgebend z.B. durch Pressen bearbeitet.To request the desired profiles with e.g. To obtain polycrystalline synthetic diamond plates available today, which are available, for example, in the form of circular disks with a thickness of 1.5 or 3.2 mm and with a diameter of 13.7 mm, the plates are produced by means of spark erosion or by means of an electron or laser Jet or a hot oxygen jet or by grinding or shaping, for example processed by pressing.

Heitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung der Zeichnung.Further details, advantages and features of the invention will become apparent from the following description of the drawing.

Es zeigen:

  • Fig. 1 ein erfindungsgemäßes Abrichtwerkzeug in Form einer Abrichtrolle in Seitenansicht,
  • Fig. 2 das Abrichtwerkzeug nach Fig. 1 in Draufsicht
  • Fig. 3 einen Abrichtblock in Seitendarstellung und
  • Fig. 4 eine Schnittdarstellung des Abrichtblockes nach Fig. 3.
Show it:
  • F ig. 1 a dressing tool according to the invention in the form of a dressing roller in side view,
  • Fig. 2, the dressing tool of FIG. 1 in plan view
  • Fig. 3 is a dressing block in side view and
  • F ig. 4 shows a sectional illustration of the dressing block according to FIG. 3.

In Fig. 1 ist eine erfindungsgemäße Abrichtrolle 10 dargestellt, die aus einem Grund- oder Schaftkörper 12 besteht, der im Ausführungsbeispiel acht Segmente 14 aufweist. Auf den Brustflächen der Segmente 14 sind Hartmetallplättchen 16 angeordnet. Auf diesen ist im Kopfbereich jeweils ein Trägermaterial 20 befestigt, das zur Halterung von profilierten Platten 18 polykristallinen synthetischen Diamants dient. Das Trägermaterial 20 ist vorzugsweise in Form einer Hartmetallunterlage ausgebildet. Selbstverständlich kann ein anderer Schneidstoff als polykristalliner synthetischer Diamant Verwendung finden und auch unmittelbar auf den Brustflächen angeordnet sein.1 shows a dressing roller 10 according to the invention, which consists of a base or shaft body 12, which in the exemplary embodiment has eight segments 14. Tungsten carbide plates 16 are arranged on the chest surfaces of the segments 14. A carrier material 20, which serves to hold profiled plates 18 polycrystalline synthetic diamonds, is fastened to these in the head region. The carrier material 20 is preferably in the form of a hard metal base. Of course, a cutting material other than polycrystalline synthetic diamond can be used and can also be arranged directly on the chest surfaces.

Wie das zeichnerische Ausführungsbeispiel nach Fig. 2 verdeutlicht, ist häufig mehr als ein Diamantplättchen 18 (ausgefüllte Fläche) auf einer Brustfläche eines Segments 14 angeordnet, um ein gewünschtes Profil zu Verfügung zu stellen. Damit der Stoß zwischen den synthetischen Diamantplättchen 18 beim Abrichten von Schleifscheiben die geometrische Genauigkeit nicht beeinflußt, also der Stoß zum Beispiel nicht zu einer unerwünschten Vertiefung oder Erhebung auf der Schleifscheibe führt, sind die Diamantplättchen 18 auf aufeinanderfolgenden Segmenten 14 versetzt zueinander angeordnet. Dadurch erfolgt eine Überlappung im Stoßbereich bei drehender Abrichtrolle, so daß eine überaus präzise geometrische Genauigkeit der Schleifscheibe auch weiterhin gewährleistet ist. Wie die Fig. 2 verdeutlicht, sind auf einem Segment 22 zwei synthetische Diamantplättchen 18 angeordnet, wohingegen auf dem nachfolgenden Segment 24 nur ein einziges Diamantplättchen 18 vorgesehen ist, welches genau im Stoßbereich der Platten 18 des vorausgehenden Segments 22 angeordnet ist.As the drawing embodiment of FIG. 2 illustrates, there is often more than one diamond plate 18 (filled area) on a chest surface of a segment 14 arranged to provide a desired profile. So that the joint between the synthetic diamond plates 18 does not influence the geometric accuracy when dressing grinding wheels, that is, for example, the joint does not lead to an undesired deepening or elevation on the grinding wheel, the diamond plates 18 are arranged offset on one another on successive segments 14. This results in an overlap in the joint area when the dressing roller rotates, so that an extremely precise geometric accuracy of the grinding wheel is still guaranteed. As illustrated in FIG. 2, two synthetic diamond plates 18 are arranged on a segment 22, whereas only a single diamond plate 18 is provided on the following segment 24, which is arranged exactly in the joint area of the plates 18 of the preceding segment 22.

Im Ausführungsbeispiel ist zwar ein einfaches von den Diamantplatten 18 gebildetes Profil dargestellt, jedoch kann dieses selbstverständlich beliebige Formen aufweisen. Um eine entsprechende Bearbeitung der Diamantplatten zur Herstellung eines gewünschten Profils durchzuführen, wird erfindungsgemäß vorgeschlagen, die Diamantplatten mittels Funkenerosion oder mittels eines Elektronen- oder Laser-Strahls oder eines heißen Sauerstoffstrahls und entsprechend hochgespanntes Druckwasser oder durch Schleifen oder formgebend z.B. durch Pressen zu bearbeiten. Dadurch ist eine hohe Präzision der Profile der Diamantplättchen 18 gewährleistet, so daß bei dem Einsatz des erfindungsgemäßen Abrichtwerkzeugs 10 eine Schleifscheibenarbeitsfläche zur Verfügung gestellt wird, die sich nicht nur durch die geometrische Genauigkeit, sondern auch durch die überaus hohe Schärfe, die zu einer längeren Standzeit führt, auszeichnet.Although a simple profile formed by the diamond plates 18 is shown in the exemplary embodiment, this can of course have any shape. In order to carry out a corresponding processing of the diamond plates to produce a desired profile, it is proposed according to the invention to process the diamond plates by means of spark erosion or by means of an electron or laser beam or a hot oxygen beam and correspondingly high-pressure water or by grinding or shaping, for example by pressing. This ensures a high precision of the profiles of the diamond plates 18, so that when using the dressing tool 10 according to the invention, a grinding wheel work surface is provided Is made available, which is characterized not only by the geometric accuracy, but also by the extremely high sharpness, which leads to a longer service life.

Um die -beim Bearbeiten einer Schleifscheibe anfallenden abgetragenen stumpf gewordenen Schleifkörner und Metallpartikel auf einfache Weise zu entfernen, ist vor den Zähnen 14 jeweils eine Spankammer 26 vorgesehen, in die die entsprechenden Teile aufgenommen werden können. Ein aufwendiges Entfernen der entsprechenden Teilchen ist wie bei einem Einsatz bekannter Abrichtwerkzeuge mit durchgehenden mit Diamantkörnern besetzten Flächen versehenen Abrichtrollen nicht erforderlich.In order to remove the abraded abrasive grains and metal particles which have become worn away when machining a grinding wheel, a chip chamber 26 is provided in front of the teeth 14, into which the corresponding parts can be accommodated. A complex removal of the corresponding particles is not necessary, as is the case when using known dressing tools with continuous dressing rollers provided with diamond grains.

In Fig. 3 ist in Seitenansicht ein Abrichtblock 30 dargestellt, der Vorsprünge 32 aufweist, auf deren Brustflächen Schneidstpffe 34 angeordnet sind. Dabei handelt es sich bei den Schneidstoffen 34 um harte oder überharte Materialien, die aus einer kompakten Einheit in Form fertiger profilierter Platten oder aus mit den Schneidstoffen beschichteten Grundkörpern bestehen. Die Vorsprünge 32 können dabei integraler Bestandteil des Grundkörpers 28 oder auf diesem befestigt sein.In Fig. 3 a side view of a truing block 30 is shown having the projections 32, p their chest surfaces Schneidst ffe 34 are arranged. The cutting materials 34 are hard or superhard materials which consist of a compact unit in the form of finished profiled plates or of base bodies coated with the cutting materials. The projections 32 can be an integral part of the base body 28 or can be fastened thereon.

Im Ausführungsbeispiel nach Fig. 3 finden profilierte Platten aus polykristallinem synthetischem Diamant Verwendung, die ihrerseits mittels eines Trägermaterials (das gleichzeitig die Vorsprünge bildet) mit dem Grundkörper 28 verbunden sind.' Wie bei der Abrichtrolle 10 befinden sich auch beim Abrichtblock 28 Spankammern 36 vor den Vorsprüngen.3, profiled plates made of polycrystalline synthetic diamond are used, which in turn are connected to the base body 28 by means of a carrier material (which at the same time forms the projections). ' As with the dressing roller 10, there are also chip chambers 36 in front of the projections in the dressing block 28.

In Fig. 4 ist eine Vorderansicht des erfindungsgemäßen Ab-richtblockes 30 dargestellt und verdeutlicht, daß die Profilfläche eines Vorsprunges aus mehreren bearbeiteten Platten harten oder überharten Materials zusammengesetzt ist.Strength in F. 4 is a front view of the invention A b-directing block 30 is shown and illustrates that the profile surface is composed of a projection of a plurality of machined plates hard or hard material.

Sowohl bei der erfindungsgemäßen Abrichtrolle wie -block ergibt sich der weitere Vorteil, daß ein Nachbearbeiten ohne Schwierigkeiten möglich ist, da die auf den Brustflächen angeordneten profilierten Platten des Schneidstoffs nachprofiliert und gegebenenfalls ausgewechselt werden können.Both in the dressing roller and block according to the invention, there is the further advantage that reworking is possible without difficulty, since the profiled plates of the cutting material arranged on the chest surfaces can be re-profiled and, if necessary, replaced.
