Description
Die Neuerung betrifft eine Schleifscheibe, die drehbar oder feststehend an einer Halterung angebracht ist. Drehbare Schleifscheiben dieser Art sind einstückig ausgebildet und werden zum Beispiel bei der Bearbeitung von harten, metallischen Dichtsitzen in Armaturen verwendet. Die Nachteile derartiger Schleifscheiben bestehen darin, daß nach Verschleiß des Schleifmittels die ganze Schleifscheibe zuerst sorgfältig ausgebaut und dann in ihrer Gesamtheit entsorgt werden muß.The innovation concerns a grinding wheel that is mounted on a holder in a rotatable or fixed manner. Rotatable grinding wheels of this type are made in one piece and are used, for example, for machining hard, metallic sealing seats in fittings. The disadvantages of such grinding wheels are that once the abrasive has worn out, the entire grinding wheel must first be carefully removed and then disposed of in its entirety.
Der Neuerung liegt die Aufgabe zugrunde, eine Schleifscheibe der eingangs beschriebenen Art zu schaffen, die zweiteilig aus einem Schleifscheibengrundkörper und einem damit lösbar verbundenen, mit einer Schleiffläche versehenen Schleifscheibenaufsatz gebildet ist, der am Schleifscheibengrundkörper zentriert ist und dessen Materialstärke höchstens 50 % der maximalen Materialstärke des Schleifscheibengrundkörpers beträgt. Dieser Schleifscheibenaufsatz ist leicht auszuwechseln, so daß nicht mehr die Schleifscheibe als ganzes entsorgt werden muß. Dies führt aufgrund des deutlich niedrigeren Materialverbrauchs sowohl zu geringeren Herstellungs- als auch Entsorgungskosten. Die Kosten für Montage und Demontage sind sehr gering.The innovation is based on the task of creating a grinding wheel of the type described above, which is made up of two parts: a grinding wheel base body and a grinding wheel attachment which is detachably connected to it and has a grinding surface, which is centered on the grinding wheel base body and whose material thickness is at most 50% of the maximum material thickness of the grinding wheel base body. This grinding wheel attachment is easy to replace, so that the grinding wheel no longer has to be disposed of as a whole. This leads to lower manufacturing and disposal costs due to the significantly lower material consumption. The costs for assembly and disassembly are very low.
Der Schleifscheibengrundkörper kann mit Schleifpapier belegt und somit auch allein zum Schleifen eingesetzt werden. Dadurch ist immer eine Reserveschleifscheibe am Bearbeitungsort vorrätig.The grinding wheel base can be covered with sandpaper and can therefore also be used for grinding alone. This means that a spare grinding wheel is always available at the processing location.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß der Schleif-Scheibenaufsatz mit einer Schleifmittelbeschichtung versehen oder mit Schleifpapier bestückbar und somit für verschiedenste Schleifarbeiten einsetzbar ist.According to the innovation, the grinding wheel can be designed in such a way that the grinding wheel attachment can be provided with an abrasive coating or can be fitted with sandpaper and can thus be used for a wide variety of grinding work.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß als Befestigungsvorrichtung ein Bajonett- oder Klemmverschluß vorgesehen ist. Derartige Ver-Schlüsse erlauben ein schnelles Auswechseln des Schleifscheibenaufsatzes.According to the innovation, the grinding wheel can be designed in such a way that a bayonet or clamp closure is provided as a fastening device. Such closures allow the grinding wheel attachment to be changed quickly.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß die Befestigungsvorrichtung für links- und rechtsdrehendes Schleifen ausgeführt und somit für alle gängigen Systeme einsetzbar ist.According to the innovation, the grinding wheel can be designed in such a way that the fastening device is designed for left- and right-hand grinding and can therefore be used for all common systems.

Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß jeweils nur eine Schleifscheibe für eine Schleifbearbeitung eingesetzt ist, was eine gezielte Bearbeitung von Kleinkörpern erlaubt.According to the innovation, the grinding wheel can be designed in such a way that only one grinding wheel is used for grinding at a time, which allows targeted machining of small bodies.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß mehrere fest oder sich drehend gelagerte Schleifscheiben über eine mehrarmige Vorrichtung miteinander verbunden, sich um eine gemeinsame Achse drehend, für eine Schleifbearbeitung eingesetzt sind. Dies dient insbesondere der gleichmäßigen Bearbeitung von Großflächen.According to the innovation, the grinding wheel can be designed in such a way that several fixed or rotating grinding wheels are connected to one another via a multi-arm device and rotate about a common axis and are used for grinding. This is particularly useful for the uniform processing of large surfaces.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß die Schleifscheibenaufsatz aus verschiedenen Materialien, vorzugsweise Metall, besteht.According to the innovation, the grinding wheel can be designed in such a way that the grinding wheel attachment consists of different materials, preferably metal.
Die Schleifscheibe kann neuerungsgemäß derart ausgebildet sein, daß die Materialstärke des Schleifscheibenaufsatzes höchstens 30 % der maximalen Materialstärke des Schleifscheibengrundkörpers beträgt. Damit werden die Kosten für Herstellung und Entsorgung erheblich gemindert.According to the innovation, the grinding wheel can be designed in such a way that the material thickness of the grinding wheel attachment is no more than 30% of the maximum material thickness of the grinding wheel base body. This significantly reduces the costs of production and disposal.
Im folgenden wird anhand zweier Figuren eine mögliche Ausführungsform der neuerungsgemäßen Schleifscheibe vorgestellt.In the following, a possible embodiment of the grinding wheel according to the innovation is presented using two figures.

Figur 1 zeigt einen mittels Bajonettverschluß 4 an einen Schleifscheibengrundkörper 1 angebrachten Schleifscheibenaufsatz 3, wobei die Niete 5 des Bajonettverschlusses 4 derart ausgebildet ist, daß ein einwandfreies Schleifen auch allein mit dem mit einer Schleiffläche ausrüstbaren Schleifscheibengrundkörper 1 gewährleistet ist.Figure 1 shows a grinding wheel attachment 3 attached to a grinding wheel base body 1 by means of a bayonet lock 4, wherein the rivet 5 of the bayonet lock 4 is designed in such a way that perfect grinding is also ensured solely with the grinding wheel base body 1 which can be equipped with a grinding surface.
Figur 2 zeigt einen Schleifscheibenaufsatz 3 mit Schleiffläche 2 und drei Bohrungen 6 zur Befestigung mittels Bajonettverschluß an dem Schleifscheibengrundkörper 1.Figure 2 shows a grinding wheel attachment 3 with grinding surface 2 and three holes 6 for fastening to the grinding wheel base body 1 by means of a bayonet lock.
