Definitions
- the invention further relates to a method for producing a carrier body for a grinding or cutting tool.
- the invention relates to a grinding or cutting tool and a method for producing a grinding or cutting tool.
- Carrier bodies made of metal are preferably used, which are ring-shaped or circular.
- a circular support body When using a circular support body, however, the problem arises that due to the circular shape when cutting the support body from a base material, there is a lot of waste. This waste is also increased by, for example, still having to separate an inner circle from the circular carrier body. In other words, especially in the production of ring-shaped carrier bodies, there is a high waste due to the inner and outer circle.
- Blanks, which are designed as hollow cylinders are considerably more expensive to purchase than, for example, plate material.
- Another disadvantage is that due to the size of a circular or annular support body, correspondingly larger machining centers or machines are also required.
- the object of the present invention is to provide a carrier body for a grinding or cutting tool which is more economical compared to the prior art because of a smaller amount of waste and can also be produced on smaller machine sizes.
- Another object of the present invention is to provide a method for producing such a carrier body, in which smaller amounts of waste and smaller machine sizes can be used.
- the object of the present invention is to produce a grinding or cutting tool which is more economical than the prior art and to provide a method for producing such a grinding or cutting tool with the same economic aspect.
- the carrier body comprises at least two, preferably exactly three, carrier body segments, which are essentially circular or annular segment-shaped in the cross-sectional plane and are connected to one another via at least one form-fit connection, ensures that the carrier body does not have its overall, unfavorable geometric shape Form must be separated from a base body, which leads to a minimization of waste.
- the carrier body has at least one side surface arranged substantially parallel to the cross-sectional plane and / or at least one peripheral surface, at least one, preferably groove-shaped and / or substantially circular segment-shaped, recess on the side surface and / or the peripheral surface for connecting at least one grinding or cutting surface , is formed, it is possible that a better connection to the grinding or cutting surface is produced by this depression on the side surface or peripheral surface. If the grinding or cutting surface is only applied directly to the side surface or the peripheral surface (for example, sintered or glued), the connection to the carrier body is not as stable as that of a Connection via a designated deepening. The recess not only creates an adhesive connection, but also a positive connection, which counteracts cutting forces and radial forces such as centrifugal forces, etc. that arise when using the grinding or cutting tools.
- the at least one form-fit connection comprises at least one, preferably dovetail-shaped, pin and at least one corresponding recess, and / or at least one plug connection
- the forces are absorbed between the segments due to the form-fit connection.
- a positive connection also makes it easier to join the individual carrier body segments (for example, like a puzzle or model railroad tracks) and prevents this connection from being opened accidentally. This is supported by, for example, establishing a dovetail-shaped connection. Incorrect assembly is prevented due to a pin and recess connection.
- the forces that arise when using the grinding or cutting tool can be better reduced by a stable form-fit connection and distributed in the carrier body.
- the carrier body consists essentially of steel and / or has at least one coupling element for coupling the carrier body to a rotary drive of a processing machine, preferably a grinding machine
- a stable carrier body is created which can be connected to the rotary drive of the processing machine via the coupling elements.
- Steel is easy to process thanks to various processes and is extremely stable. It is also inexpensive to purchase.
- the grinding or cutting tool produced in this way can be arranged on different machines on account of possible different coupling elements.
- the method according to the invention for producing the at least one support body comprises the following work steps, the at least two support body segments in a first process step comprising a common plate-shaped or hollow-cylindrical base body, preferably by means of a laser, are cut out or cut off, separated in a second process step, and in a third process step via which at least one interlocking connection is connected to one another to form the at least one support body, an economical method for producing a support body is achieved in which high waste minimization and small Machine sizes can be used.
- a grinding or cutting tool in particular for processing the edges and edges of tiles and bricks, comprises at least one carrier body and at least one grinding or cutting covering, which is arranged on at least one surface of the at least one carrier body, preferably on at least one essentially parallel an inexpensive and economical grinding or cutting tool is produced to the cross-sectional plane and / or at least one peripheral surface of the at least one carrier body, in particular when the carrier body consists of individual carrier body segments, as described above.
- the grinding or cutting covering can be attached to the carrier body, for example, via inseparable connections such as gluing, sintering, soldering or the like. This creates a strong connection between the grinding or cutting surface and the cutting tool; the carrier body segments are held together not only by the form-fitting connections, but also by the non-releasable connections described above.
- detachable connections can also be provided, which fasten the grinding or cutting covering, for example by means of screws, to the carrier ring or to the carrier body.
- the at least one abrasive or cutting surface is connected to the at least one surface via at least one, preferably abrasive-free, binder and the at least one abrasive or cutting surface is connected to the at least one surface of the at least one carrier body via at least one, preferably abrasive-free, binder wherein the at least one binding agent is arranged at least in regions in at least one recess formed in the at least one surface, an additional stable layer is introduced between the grinding and cutting covering, which increases the stability of the grinding or cutting tool.
- the binder can be provided in the form of a chemical or a mechanical binder.
- the binder can thus be, for example, a powder which liquefies at least in sections during sintering and connects to the carrier body and the cutting or grinding covering.
- the binder can also be an adhesive, a solder, or something similar.
- the use of a mechanical binder, such as a screw, rivet or something similar, can also be provided.
- the grinding or cutting tool has at least one metal-bonded abrasive coating with diamond as an abrasive, a high-quality grinding or cutting tool is produced in spite of the very economically produced carrier body.
- a carrier body as described above is provided in a method for producing a grinding or cutting tool in a first method step and at least one grinding or cutting coating is arranged on the at least one surface of the carrier body in a second method step, an economical method for producing a Grinding or cutting tool, especially when the carrier body is inserted in a sintering mold in the course of a second method step, material for forming the at least one grinding or cutting covering and optionally at least one between the at least one grinding or cutting covering and the at least one Surface of the carrier body arranged binding in the sintered form is filled, and a sintering process is carried out in order to sinter the at least one grinding or cutting coating onto the carrier body.
- the grinding or cutting tool is cleaned after the second method step and the grinding or cutting tool is cleaned, turned off and / or with at least one coupling element for coupling the grinding or cutting tool to a rotary drive after the second method step
- Processing machine preferably grinding machine is provided, the finished cutting tool can thus be balanced and geometrically corrected applied to a processing machine.
- the Fig. 1a shows three carrier body segments 2, with two of these carrier body segments 2 already being connected to one another by the positive connection 3.
- the positive connection 3 essentially consists of a pin 8 and a corresponding recess 9.
- other shapes are also conceivable. It is important that the pin 8 and the recess 9 essentially match each other geometrically and thereby each have corresponding counter-shapes.
- the interlocking connection 3 is always located on a contact section 13 of the respective carrier body segment 2.
- the interlocking connection 3 is determined by an area which protrudes from this contact section 13 and which can be connected to a geometrically corresponding area which projects into the contact section 13.
- This form-fitting connection is of course to be regarded as very advantageous if it has an undercut that can prevent the individual carrier body segments from accidentally falling apart.
- This undercut can - as in the Fig. 1 shown, be formed by a simple circular pin 8, which is connected to the contact section 13 via a web 15.
- Fig. 1b one sees the completely assembled carrier body 1, which in this example is formed by 3 carrier body segments 2, which have been assembled via the form-fitting connections 3.
- a side surface 4 and a peripheral surface 5 are formed.
- Cutting or grinding documents can then be applied either to the side surface 4 and / or the peripheral surface 5.
- This cutting or grinding covering can be formed by geometrically determined cutting and / or also by geometrically indefinite cutting (abrasive grains, etc.).
- a cup grinding wheel is shown as an example.
- This has an annular support body 1, which is characterized by at least two Carrier body segments 2 composed. These are connected to one another at the contact section 13 via the positive connection 3.
- the entire carrier body 1 can be connected to a processing machine via at least one coupling element 11. This is shown schematically in the Fig. 3 evident. Where the rotary drive 41 one in the Fig. 3 not visible processing machine is shown.
- the stability on the grinding or cutting tool 40 is thus achieved not only by the positive connection 3 on the contact sections 13 of the individual carrier body segments 2, but also by the binder 12 and the cutting or grinding covering 7 located thereon.
- Fig. 3 shows the section AA from the Fig. 2 . It can be seen that the recess 6 in the carrier body 1 takes up part of the binder 12 and thus produces a positive connection. The binder 12 also creates the connection to the cutting or grinding covering 7.
- a connection between the processing machine and the grinding or cutting tool 40 is established via the coupling element 11, in this case a through hole, through which a screw connection is made in the rotary drive 41.
- the screw connection was not shown in the figure.
- the inner ring of the annular carrier body 1 could also be used as a coupling element.
- this could also have a thread, for example, with which the carrier body 1 could be applied to a spindle of a rotary drive 41.
- a thread instead of a thread, a clamping cone or something similar would also be conceivable.
- Fig. 4a shows the corresponding recess 9 of a positive connection 3. This extends into the interior of a carrier body segment 2 and serves to receive the in the Fig. 4b corresponding pin 8 shown.
- a kind of dovetail connection is shown, which is characterized by large, interlocking surfaces that have a high force absorption potential.
- all transitions of the individual surfaces are formed by radii r in order to be able to prevent a notch effect with subsequent breaking off or breaking out of the material. Since the forces due to the high rotational speeds on the carrier body 1 are at least partially absorbed via the interlocking connections 3, care must be taken to ensure a homogeneous distribution of forces in order to prevent breaks. For this reason, angular interlocking connections with notches or deep recesses should be avoided.
- Fig. 5a shows a variant with two pins 8 of the same design on a contact section 13 of a carrier body segment 2. It is thus provided that at the first contact section 13 of the carrier body segment 2 two pins 8 project outwards, while the corresponding recesses 9 are arranged on the opposite contact section 13 '.
- the number of interlocking connections 3 per contact section 13 can vary depending on the degree of loading of the carrier body 1.
- FIG. 5b it is shown how two opposite form-locking connections 3 are located on a contact section 13.
- a pin 8 protrudes from a contact section 13, while a corresponding recess 9 projects into the contact section 13.
- a corresponding receptacle 9 and a corresponding pin 8 are formed on the opposite contact section 13 'in a geometrically adapted manner.
- a plurality of depressions 6 are formed on different diameters of the annular carrier body 1. This can be advantageous if a wider grinding or cutting surface 7 has to be applied to the rotating body 1 and an improved connection is necessary.
- the interlocking connection 3 consists, so to speak, of an additional connecting element. This is also dovetail-shaped and is inserted as a plug connection between the two carrier segments 2.
- Fig. 6a shows a carrier body 1 for a peripheral grinding or cutting tool 40.
- the recess 6 is located in the peripheral surface 5 of the carrier body 1. This recess 6 is also used here for better connection with a grinding or cutting surface 7, as in the Fig. 6b shown.
- the Fig. 6b shows a grinding or cutting tool 40 with a cutting or grinding covering 7 arranged on the circumference.
- the individual carrier body segments 2 are also connected to one another here by means of interlocking connections 3.
- Coupling elements 11 are also created, with which a connection to a processing machine can take place.
- a cutting or grinding covering 7 arranged on the side surfaces 4 can also be arranged.
- the peripheral surface 5 but also the side surface 4 or both side surfaces 4 would be provided for receiving a cutting or grinding covering 7, which extends the intended use of the grinding or cutting tool 40.
- FIG. 7a, 7b shows that it is not a circular carrier body 1 that is produced, but a full circle carrier body 1. However, here too, waste amounts can be reduced by cutting or punching out carrier body segments 2. The machine size can also be reduced.
- Fig. 7b it is shown how the individual carrier body segments 2, when plugged together, form a fully circular carrier body 1. This can also have depressions 6.
- the individual carrier body segments 2 are also assembled here via the contact sections 13 and the interlocking connections 3 located thereon.
- a carrier body 1 is formed by this at least two - in this example by three - inserted or engaging carrier body segments 2.
- the interlocking connections 3 cannot be inserted parallel to the axis of rotation of the carrier body 1, but rather radially to the axis of rotation of the carrier body 1.
- Fig. 9 it is shown how the depressions 6 do not extend annularly on the carrier body 1, but are aligned radially to the latter. In this way, an improved connection between the carrier body 1 and the cutting or grinding covering 7 can also be produced.
- Fig. 10 shows a carrier body 1 consisting of a plurality of carrier body segments 2, which are connected to one another via contact sections 13 and positive connections 3 located thereon.
- a cutting tool with geometrically determined cutting edges is shown instead of an abrasive coating which essentially consists of geometrically undefined abrasive grains. It is thus possible not only to produce grinding wheels, but also, for example, milling cutters, drills or the like, a segmented carrier body 1 being used.
- the individual carrier body segments 2 can be connected to one another via fastening elements 14. These prevent the interlocking connections 3 from slipping apart.
- a screw connection serves as the binding agent 12 between the cutting or grinding covering 7 and the carrier body 1.
- the recess 6, which is not visible in this case, is designed as a thread or as a through-hole, which is used to receive the screw serving as the binder 12.
- Fig. 11 shows the method for producing the grinding or cutting tool 40.
- a first step a plurality of carrier body segments 2 are cut or cut from a base body 50.
- the base body 50 can be plate-shaped or strip-shaped material - for example metal plates or colloquially sheet metal plates. However, it can also be provided that the base body is designed as a hollow cylindrical base body from which the segments are cut off.
- the carrier body segments 2 are eroded out of the base body by means of wire erosion.
- Other options would be at thin-walled plates or strip material also punching out the individual carrier body segments 2.
- the carrier body segments 2 are separated.
- the wells 6 in the Fig. 2 shown) can, for example, be arranged on the carrier body segments 2 when they are cut out of the base material 50.
- this step can only be carried out at a later time.
- the creation of the coupling elements 11 (for example through bores for fastening the carrier body 1 to a rotary drive of a processing machine) can also take place in the course of creating the depressions 6 or at a later or earlier point in time.
- the separated carrier body segments 2 are put together to form a ring or a full circle and form the carrier body 1.
- the carrier body segments 2 can also be assembled in a sintered mold 52. It is also possible to put the entire carrier body 1 together beforehand and only then to place it in the sintered mold 52.
- the contact sections 13 and the form-fitting connections 3 before assembly of the carrier body segments 2, for example with an adhesive, to ensure an additional bond. Provision can also be made for the gap between the individual carrier body segments to be closed or filled at least in sections after being plugged together by means of adhesive or another binder (for example soldering or spot welding) in order to ensure a more stable connection.
- a connection can take place between the carrier body segments 2 by introducing an additional means between the carrier body segments 2.
- a temperature-related diffusion of the material between the carrier body segments 2 can also take place, which connects them to one another.
- the binder 12 is applied to the carrier body 1. This is preferably done in a recess 6 which is located on at least one of the side surfaces or peripheral surface of the carrier body 1.
- the binder 12 can be applied both in powder form, in liquid form, in strip form or as a paste.
- the grinding or cutting covering 7 is applied to the carrier body 1.
- the grinding or cutting covering 7 can, for example, be applied in powder form and positioned by means of molding in a correct position on the carrier body 1, or also from “green body” which has been pre-pressed in a separate area and is placed on the carrier body 1.
- the binder 12 is formed by an adhesive and the grinding or cutting surface 7 is simply connected to the carrier body 1 by this adhesive. Subsequent sintering can therefore fail.
- the grinding or cutting body 7 is connected by sintering with the binder 12 and the carrier body 1, which takes place in a sintering furnace 53.
- the grinding or cutting tool 40 is dressed if necessary. This dressing takes place, for example, via a dressing tool 54. It can also be provided that the coupling element 11 (see Fig. 2 ) is only introduced in the course of this last work step. In this last step, the grinding or cutting tool 40 is finished and prepared for use.

Description
Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines Trägerkörpers für ein Schleif- oder Schneidwerkzeug.The invention further relates to a method for producing a carrier body for a grinding or cutting tool.
Schließlich betrifft die Erfindung ein Schleif- oder ein Schneidwerkzeug und ein Verfahren zur Herstellung eines Schleif- oder Schneidwerkzeugs.Finally, the invention relates to a grinding or cutting tool and a method for producing a grinding or cutting tool.
Schleif- oder Schneidwerkzeuge und Verfahren zu deren Herstellung sind bereits bekannt und zählen zum Stand der Technik. Dabei werden bevorzugt Trägerkörper aus Metall verwendet, welche ringförmig oder kreisförmig ausgebildet sind. Bei der Verwendung eines kreisförmigen Trägerkörpers ergibt sich jedoch das Problem, dass sich aufgrund der Kreisform beim Herausschneiden des Trägerkörpers aus einem Grundmaterial sehr viel Verschnitt ergibt. Dieser Verschnitt wird zudem erhöht, indem beispielsweise noch ein Innenkreis aus dem kreisförmigen Trägerkörper herausgetrennt werden muss. In anderen Worten ergibt sich vor allem bei der Herstellung von ringförmigen Trägerkörpern aufgrund des Innen- und Außenkreises ein hoher Verschnitt. Auch bei der Verwendung eines Hohlzylinders als Grundkörper für einen derartigen Trägerring entstehen höhere Kosten. Rohlinge, welche als Hohlzylinder ausgebildet sind, sind in der Anschaffung erheblich teurer als beispielsweise Plattenmaterial.Grinding or cutting tools and methods for their production are already known and belong to the prior art. Carrier bodies made of metal are preferably used, which are ring-shaped or circular. When using a circular support body, however, the problem arises that due to the circular shape when cutting the support body from a base material, there is a lot of waste. This waste is also increased by, for example, still having to separate an inner circle from the circular carrier body. In other words, especially in the production of ring-shaped carrier bodies, there is a high waste due to the inner and outer circle. Even when a hollow cylinder is used as the base body for such a carrier ring, higher costs arise. Blanks, which are designed as hollow cylinders, are considerably more expensive to purchase than, for example, plate material.
Nachteilig ist zudem, dass aufgrund der Größe eines kreisförmigen oder ringförmigen Trägerkörpers auch entsprechend größere Bearbeitungszentren oder Maschinen benötigt werden.Another disadvantage is that due to the size of a circular or annular support body, correspondingly larger machining centers or machines are also required.
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Trägerkörper für ein Schleif- oder Schneidwerkzeug zu schaffen, der aufgrund einer geringeren Verschnittmenge wirtschaftlicher gegenüber dem Stand der Technik ist und auch auf kleineren Maschinengrößen produzierbar ist.The object of the present invention is to provide a carrier body for a grinding or cutting tool which is more economical compared to the prior art because of a smaller amount of waste and can also be produced on smaller machine sizes.
Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Herstellung eines derartigen Trägerkörpers zu schaffen, bei dem geringere Verschnittmengen und kleinere Maschinengrößen verwendbar sind. Zudem besteht die Aufgabe der vorliegenden Erfindung darin, ein gegenüber dem Stand der Technik wirtschaftlicheres Schleif- oder Schneidwerkzeug herzustellen und ein Verfahren zur Herstellung eines derartigen Schleif- oder Schneidwerkzeuges mit demselben wirtschaftlichen Aspekt anzugeben.Another object of the present invention is to provide a method for producing such a carrier body, in which smaller amounts of waste and smaller machine sizes can be used. In addition, the object of the present invention is to produce a grinding or cutting tool which is more economical than the prior art and to provide a method for producing such a grinding or cutting tool with the same economic aspect.
Diese Aufgaben werden durch die Merkmale der unabhängigen Ansprüche 1, 5, 6 und 10 gelöst.These objects are solved by the features of
Dadurch, dass der Trägerkörper wenigstens zwei, vorzugsweise genau drei, Trägerkörpersegmente umfasst, welche in der Querschnittsebene im Wesentlichen kreis- oder kreisringsegmentförmig ausgebildet sind und zumindest über wenigstens eine Formschlussverbindung miteinander verbunden sind, wird erreicht, dass der Trägerkörper nicht in seiner gesamten, ungünstigen geometrischen Form aus einem Grundkörper herausgetrennt werden muss, was zu einer Verschnittminimierung führt.The fact that the carrier body comprises at least two, preferably exactly three, carrier body segments, which are essentially circular or annular segment-shaped in the cross-sectional plane and are connected to one another via at least one form-fit connection, ensures that the carrier body does not have its overall, unfavorable geometric shape Form must be separated from a base body, which leads to a minimization of waste.
Zudem wird erreicht, dass aufgrund der Segmentierung des Trägerkörpers auch kleinere Maschinengrößen verwendet werden können, um die einzelnen Trägerkörpersegmente herstellen zu können.In addition, it is achieved that, due to the segmentation of the carrier body, smaller machine sizes can also be used in order to be able to produce the individual carrier body segments.
Wenn der Trägerkörper wenigstens eine im Wesentlichen parallel zur Querschnittsebene angeordnete Seitenfläche und/oder wenigstens eine Umfangsfläche aufweist, wobei an der Seitenfläche und/oder der Umfangsfläche wenigstens eine, vorzugsweise nutförmige und/oder im Wesentlichen kreissegmentförmige, Vertiefung zur Anbindung wenigstens eines Schleif- oder Schneidbelags, ausgebildet ist, wird ermöglicht, dass durch diese Vertiefung an der Seitenfläche oder Umfangsfläche eine bessere Verbindung zum Schleif- oder Schneidbelag hergestellt wird. Wird der Schleif- oder Schneidbelag nur direkt auf die Seitenfläche oder die Umfangsfläche aufgebracht (zum Beispiel gesintert oder geklebt), wird keine so stabile Verbindung zum Trägerkörper hergestellt wie bei einer Anbindung über eine dafür vorgesehene Vertiefung. Durch die Vertiefung entsteht nicht nur eine Klebeverbindung, sondern auch eine formschlüssige Verbindung, welche bei der Verwendung der Schleif- oder Schneidwerkzeuge entstehenden Schnittkräften und Radialkräften wie Fliehkräften, etc. entgegenwirkt.If the carrier body has at least one side surface arranged substantially parallel to the cross-sectional plane and / or at least one peripheral surface, at least one, preferably groove-shaped and / or substantially circular segment-shaped, recess on the side surface and / or the peripheral surface for connecting at least one grinding or cutting surface , is formed, it is possible that a better connection to the grinding or cutting surface is produced by this depression on the side surface or peripheral surface. If the grinding or cutting surface is only applied directly to the side surface or the peripheral surface (for example, sintered or glued), the connection to the carrier body is not as stable as that of a Connection via a designated deepening. The recess not only creates an adhesive connection, but also a positive connection, which counteracts cutting forces and radial forces such as centrifugal forces, etc. that arise when using the grinding or cutting tools.
Wenn die wenigstens eine Formschlussverbindung wenigstens einen, vorzugsweise schwalbenschwanzförmigen, Zapfen und wenigstens eine korrespondierende Ausnehmung, und/oder wenigstens eine Steckverbindung, umfasst, so werden die Kräfte aufgrund der Formschlussverbindung zwischen den Segmenten aufgenommen. Eine Formschlussverbindung erleichtert zudem ein Zusammenfügen der einzelnen Trägerkörpersegmente (beispielsweise wie bei einem Puzzle oder bei Modelleisenbahnschienen) und verhindert ein versehentliches Öffnen dieser Verbindung. Dies wird unterstützt, in dem zum Beispiel eine schwalbenschwanzförmige Verbindung hergestellt wird. Ein fehlerhaftes Zusammenbauen wird aufgrund einer Zapfen- und Ausnehmungsverbindung verhindert. Die bei der Verwendung des Schleif- oder Schneidwerkzeugs auftretenden Kräfte können durch eine stabile Formschlussverbindung besser abgebaut und im Trägerkörper aufgeteilt werden.If the at least one form-fit connection comprises at least one, preferably dovetail-shaped, pin and at least one corresponding recess, and / or at least one plug connection, then the forces are absorbed between the segments due to the form-fit connection. A positive connection also makes it easier to join the individual carrier body segments (for example, like a puzzle or model railroad tracks) and prevents this connection from being opened accidentally. This is supported by, for example, establishing a dovetail-shaped connection. Incorrect assembly is prevented due to a pin and recess connection. The forces that arise when using the grinding or cutting tool can be better reduced by a stable form-fit connection and distributed in the carrier body.
Wenn der Trägerkörper im Wesentlichen aus Stahl besteht, und/oder wenigstens ein Koppelelement zur Koppelung des Trägerkörpers mit einem Drehantrieb einer Bearbeitungs-, vorzugsweise Schleifmaschine aufweist, so wird ein stabiler Trägerkörper geschaffen, der über die Koppelelemente mit dem Drehantrieb der Bearbeitungsmaschine verbunden werden kann. Stahl lässt sich aufgrund diverser Verfahren einfach bearbeiten und weist eine hohe Stabilität auf. Zudem ist er kostengünstig in der Anschaffung. Aufgrund eventueller unterschiedlich ausgeführter Koppelelemente kann das dadurch erzeugte Schleif- oder Schneidwerkzeug auf unterschiedlichen Maschinen angeordnet werden.If the carrier body consists essentially of steel and / or has at least one coupling element for coupling the carrier body to a rotary drive of a processing machine, preferably a grinding machine, a stable carrier body is created which can be connected to the rotary drive of the processing machine via the coupling elements. Steel is easy to process thanks to various processes and is extremely stable. It is also inexpensive to purchase. The grinding or cutting tool produced in this way can be arranged on different machines on account of possible different coupling elements.
Wenn das erfindungsgemäße Verfahren zur Herstellung des wenigstens einen Trägerkörpers folgende Arbeitsschritte umfasst, wobei die wenigstens zwei Trägerkörpersegmente in einem ersten Verfahrensschritt aus einem gemeinsamen platten- oder hohlzylinderförmigen Grundkörper, vorzugsweise mittels eines Lasers, aus- oder abgeschnitten werden, in einem zweiten Verfahrensschritt vereinzelt, und in einem dritten Verfahrensschritt über die wenigstens eine Formschlussverbindung miteinander zum wenigstens einen Trägerkörper verbunden werden, so wird ein wirtschaftliches Verfahren zur Herstellung eines Trägerkörpers erreicht, bei dem eine hohe Verschnittminimierung erzielt wird und kleine Maschinengrößen verwendet werden können.If the method according to the invention for producing the at least one support body comprises the following work steps, the at least two support body segments in a first process step comprising a common plate-shaped or hollow-cylindrical base body, preferably by means of a laser, are cut out or cut off, separated in a second process step, and in a third process step via which at least one interlocking connection is connected to one another to form the at least one support body, an economical method for producing a support body is achieved in which high waste minimization and small Machine sizes can be used.
Wenn ein Schleif- oder Schneidwerkzeug, insbesondere zur Bearbeitung der Kanten und Ränder von Fliesen und Ziegeln, wenigstens einen Trägerkörper und wenigstens einen Schleif- oder Schneidbelag umfasst, welcher auf wenigstens einer Fläche des wenigstens einen Trägerkörpers angeordnet ist, vorzugsweise auf wenigstens eine im wesentlichen parallel zur Querschnittsebene angeordneten Seitenfläche und/oder wenigstens einer Umfangfläche des wenigstens einen Trägerkörpers, wird ein kostengünstiges und wirtschaftliches Schleif- oder Schneidwerkzeug hergestellt, insbesondere dann, wenn der Trägerkörper aus einzelnen Trägerkörpersegmenten besteht, wie oben geschildert.If a grinding or cutting tool, in particular for processing the edges and edges of tiles and bricks, comprises at least one carrier body and at least one grinding or cutting covering, which is arranged on at least one surface of the at least one carrier body, preferably on at least one essentially parallel an inexpensive and economical grinding or cutting tool is produced to the cross-sectional plane and / or at least one peripheral surface of the at least one carrier body, in particular when the carrier body consists of individual carrier body segments, as described above.
Dadurch, dass die wenigstens zwei Trägerkörpersegmente zusätzlich zur wenigstens einen Formschlussverbindung über den wenigstens einen Schleif- oder Schneidbelag miteinander verbunden sind, wird neben der Formschlussverbindung auch zusätzlich eine Verbindung über den Schleif- oder Schneidbelag hergestellt, der sich in der zusätzlichen Stabilität des Schleif- oder Schneidwerkzeuges widerspiegelt. Der Schleif- oder Schneidbelag kann beispielsweise über nicht trennbare Verbindungen wie Aufkleben, Sintern, Löten oder dergleichen am Trägerkörper befestigt werden. Somit wird eine starke Verbindung zwischen dem Schleif- oder Schneidbelag und dem Schneidwerkzeug hergestellt, die Trägerkörpersegmente werden nicht nur durch die Formschlussverbindungen zusammengehalten, sondern auch durch die oben geschilderten nichtlösbaren Verbindungen. Es können jedoch auch lösbare Verbindungen vorgesehen sein, die den Schleif- oder Schneidbelag beispielsweise mittels Schrauben am Trägerring oder am Tragkörper befestigen.Because the at least two carrier body segments are connected to one another in addition to the at least one form-fit connection via the at least one grinding or cutting covering, a connection is also established in addition to the form-fitting connection via the grinding or cutting covering, which is reflected in the additional stability of the grinding or Cutting tool reflects. The grinding or cutting covering can be attached to the carrier body, for example, via inseparable connections such as gluing, sintering, soldering or the like. This creates a strong connection between the grinding or cutting surface and the cutting tool; the carrier body segments are held together not only by the form-fitting connections, but also by the non-releasable connections described above. However, detachable connections can also be provided, which fasten the grinding or cutting covering, for example by means of screws, to the carrier ring or to the carrier body.
Wenn der wenigstens eine Schleif- oder Schneidbelag über wenigstens ein, vorzugsweise schleifmittelfreies, Bindemittel mit der wenigstens einen Fläche und der wenigstens eine Schleif- oder Schneidbelag über wenigstens ein, vorzugsweise schleifmittelfreies, Bindemittel mit der wenigstens einen Fläche des wenigstens einen Trägerkörpers verbunden ist, vorzugsweise wobei das wenigstens eine Bindemittel zumindest bereichsweise in wenigstens einer in der wenigstens einen Fläche ausgebildeten Vertiefung angeordnet ist, so wird zwischen dem Schleif- und Schneidbelag eine zusätzliche stabile Schicht eingebracht, die die Stabilität des Schleif- oder Schneidwerkzeuges erhöht. Das Bindemittel kann dabei in Form eines chemischen oder auch eines mechanischen Bindemittels vorgesehen sein. Somit kann das Bindemittel beispielsweise ein Pulver sein, welches sich beim Sintern zumindest abschnittsweise verflüssigt und mit dem Trägerkörper und dem Schneid- oder Schleifbelag verbindet. Das Bindemittel kann jedoch auch ein Klebstoff, ein Lötmittel oder etwas Vergleichbares sein. Auch die Verwendung eines mechanischen Bindemittels, wie beispielsweise einer Schraube, Niete oder etwas Vergleichbares kann vorgesehen sein.If the at least one abrasive or cutting surface is connected to the at least one surface via at least one, preferably abrasive-free, binder and the at least one abrasive or cutting surface is connected to the at least one surface of the at least one carrier body via at least one, preferably abrasive-free, binder wherein the at least one binding agent is arranged at least in regions in at least one recess formed in the at least one surface, an additional stable layer is introduced between the grinding and cutting covering, which increases the stability of the grinding or cutting tool. The binder can be provided in the form of a chemical or a mechanical binder. The binder can thus be, for example, a powder which liquefies at least in sections during sintering and connects to the carrier body and the cutting or grinding covering. However, the binder can also be an adhesive, a solder, or something similar. The use of a mechanical binder, such as a screw, rivet or something similar, can also be provided.
Wenn das Schleif- oder Schneidwerkzeug wenigstens einen metallgebundenen Schleifbelag mit Diamant als Schleifmittel aufweist, so wird trotz dem sehr wirtschaftlich hergestellten Trägerkörper ein hochwertiges Schleif- oder Schneidwerkzeug hergestellt.If the grinding or cutting tool has at least one metal-bonded abrasive coating with diamond as an abrasive, a high-quality grinding or cutting tool is produced in spite of the very economically produced carrier body.
Wenn in einem Verfahren zur Herstellung eines Schleif- oder Schneidwerkzeuges in einem ersten Verfahrensschritt ein wie oben geschilderter Trägerkörper bereitgestellt wird und in einem zweiten Verfahrensschritt wenigstens ein Schleif- oder Schneidbelag auf der wenigstens einen Fläche des Trägerkörpers angeordnet wird, wird ein wirtschaftliches Verfahren zur Herstellung eines Schleif- oder Schneidwerkzeuges erzielt, vor allem dann, wenn der Trägerkörper im Zuge eines zweiten Verfahrensschritts in einer Sinterform eingelegt wird, Material zur Ausbildung des wenigstens einen Schleif- oder Schneidbelages und gegebenenfalls wenigstens einer zwischen dem wenigstens einen Schleif- oder Schneidbelag und der wenigstens einen Fläche des Trägerkörpers angeordneten Bindung in die Sinterform gefüllt wird, und ein Sintervorgang durchgeführt wird, um den wenigstens einen Schleif- oder Schneidbelag auf den Trägerkörper zu sintern.If a carrier body as described above is provided in a method for producing a grinding or cutting tool in a first method step and at least one grinding or cutting coating is arranged on the at least one surface of the carrier body in a second method step, an economical method for producing a Grinding or cutting tool, especially when the carrier body is inserted in a sintering mold in the course of a second method step, material for forming the at least one grinding or cutting covering and optionally at least one between the at least one grinding or cutting covering and the at least one Surface of the carrier body arranged binding in the sintered form is filled, and a sintering process is carried out in order to sinter the at least one grinding or cutting coating onto the carrier body.
Schließlich wird noch angegeben, dass das Schleif- oder ein Schneidwerkzeug nach dem zweiten Verfahrensschritt gesäubert und das Schleif- oder ein Schneidwerkzeug nach dem zweiten Verfahrensschritt gesäubert, abgedreht und/oder mit wenigstens einem Koppelelement zur Koppelung des Schleif- oder ein Schneidwerkzeugs mit einem Drehantrieb einer Bearbeitungsmaschine, vorzugsweise Schleifmaschine versehen wird, wobei das endfertige Schneidwerkzeug somit gewuchtet und geometrisch korrigiert an einer Bearbeitungsmaschine angewendet werden kann.Finally, it is also stated that the grinding or cutting tool is cleaned after the second method step and the grinding or cutting tool is cleaned, turned off and / or with at least one coupling element for coupling the grinding or cutting tool to a rotary drive after the second method step Processing machine, preferably grinding machine is provided, the finished cutting tool can thus be balanced and geometrically corrected applied to a processing machine.

Die
Die Formschlussverbindung 3 befindet sich dabei stets an einem Kontaktabschnitt 13 des jeweiligen Trägerkörpersegmentes 2. Somit wird die Formschlussverbindung 3 durch einen aus diesem Kontaktabschnitt 13 herausragenden Bereich bestimmt, welcher mit einem geometrisch korrespondierenden, in den Kontaktabschnitt 13 hineinragenden Bereich verbindbar ist.The
Diese Formschlussverbindung ist natürlich dann als sehr vorteilhaft anzusehen, wenn diese einen Hinterschnitt aufweist, der ein ungewolltes Auseinanderfallen der einzelnen Trägerkörpersegmente verhindern kann. Dieser Hinterschnitt kann - wie in der

Vorteilhaft ist zudem, wenn sich Vertiefungen 6 in diesen jeweiligen Oberflächen des Trägerkörpers 1 befinden, in welche das Bindemittel 12 eindringen kann. Somit wird die Oberfläche der Anhaftung und Bindung des Bindemittels 12 vergrößert und auch eine formschlüssige Verbindung zwischen dem Bindemittel 12 und der Vertiefung 6 hergestellt. Gerade bei diesem Beispiel eines Schleif- oder Schneidwerkzeuges 40 treten hohe Radialkräfte auf. Allein schon durch die Masse des Schneid- oder Schleifbelages 7 entstehen bei hohen Drehzahlen Fliehkräfte am Schleif- oder Schneidwerkzeug 40. Bei diesen hohen Fliehkräfte zusammen mit den auftretenden Schnittkräften muss das Bindemittel 12 zusammen mit der Vertiefung 6 dauerhaft am Trägerkörper 1 bleiben und darf dabei nicht abplatzen oder abreißen. Die Kräfte werden dabei über das Bindemittel 12 und die Vertiefung 6 an den Trägerkörper 1 weitergegeben.It is also advantageous if there are
Die Stabilität am Schleif- oder Schneidwerkzeug 40 wird somit nicht nur durch die Formschlussverbindung 3 an den Kontaktabschnitten 13 der einzelnen Trägerkörpersegmente 2 erreicht, sondern auch durch das Bindemittel 12 und den darauf befindlichen Schneid- oder Schleifbelag 7.The stability on the grinding or cutting

Dieser Arbeitsschritt kann aber auch erst zu einem späteren Zeitpunkt durchgeführt werden. Auch das Schaffen der Koppelelemente 11 (beispielsweise Durchgangsbohrungen zum Befestigen des Trägerkörpers 1 an einem Drehantrieb einer Bearbeitungsmaschine) kann im Zuge der Schaffung der Vertiefungen 6 oder zu einem späteren oder früheren Zeitpunkt erfolgen.However, this step can only be carried out at a later time. The creation of the coupling elements 11 (for example through bores for fastening the
In einem nächsten Arbeitsschritt werden die vereinzelten Trägerkörpersegmente 2 zu einem Ring oder zu einem Vollkreis zusammengesteckt und bilden den Trägerkörper 1 aus. Das Zusammensetzen der Trägerkörpersegmente 2 kann auch bereits in einer Sinterform 52 erfolgen. Es ist auch möglich, vorher den gesamten Trägerkörper 1 zusammenzustecken und erst darauffolgend in die Sinterform 52 zu legen.In a next step, the separated

Nach dem Einlegen des Trägerkörpers 1 in die Sinterform 52 wird das Bindemittel 12 auf den Trägerkörper 1 aufgebracht. Vorzugsweise erfolgt dies in einer Vertiefung 6, welche sich an zumindest einer der Seitenflächen oder Umfangsfläche des Trägerkörpers 1 befindet.After the
Das Bindemittel 12 kann sowohl in Pulverform, in Flüssigform, in Streifenform oder als Paste aufgetragen werden.The
In einem weiteren Arbeitsschritt wird der Schleif- oder Schneidbelag 7 auf den Trägerkörper 1 aufgebracht. Der Schleif- oder Schneidbelag 7 kann beispielsweise pulverförmig aufgetragen werden und mittels Formen in einer korrekten Position am Trägerkörper 1 positioniert werden, oder auch aus "Grünling", der in einem gesonderten Bereich vorgepresst worden ist und auf dem Trägerkörper 1 aufgelegt wird.In a further step, the grinding or cutting
Die tatsächliche Durchhärtung des Schleif- oder Schneidbelags 7 erfolgt dann im Zuge des Sinterns, während dies eine Verbindung mit dem Bindemittel 12 und dem Trägerkörper 1 eingeht.The actual hardening of the grinding or cutting covering 7 then takes place in the course of the sintering, while this forms a connection with the
Es kann aber auch vorgesehen sein, dass das Bindemittel 12 durch einen Kleber ausgebildet wird und der Schleif- oder Schneidbelag 7 einfach durch diesen Kleber mit dem Trägerkörper 1 verbunden wird. Ein anschließendes Sintern kann somit ausfallen.However, it can also be provided that the
