Abstract

A rotatable or stationary grinding disk is mounted on afixing device is comprised of two parts consisting of a body (1) and an exchangeable adapter fitted with a grinding surface (2) and releasably connected to said grinding disk (3).The thickness of the grinding disk adapter (3) which is centered on the grinding disk (1) is at the most 50 % as thick as the body of the said grinding disk. Consequently a used grinding grinding disk adapter (3) can be easily changed, whereby the entire grinding disk no longer needs to be disposed of. This results in lower manufacturing and disposal costs because of the significantly smaller amount of materials used.

Description

Schleifscheibe grinding wheel
Beschreibungdescription
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 beste- hen 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 attached to a holder so that it can rotate or be fixed. Rotatable grinding wheels of this type are made in one piece and are used, for example, when machining hard, metallic sealing seats in fittings. The disadvantages of grinding wheels of this type are that after 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 in the introduction, which is formed in two parts from a grinding wheel base body and a releasably connected grinding wheel attachment provided with 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 is. This grinding wheel attachment is easy to replace, so that the grinding wheel as a whole no longer has to be disposed of. Due to the significantly lower material consumption, this leads to lower production and disposal costs. 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 base of the grinding wheel can be coated 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 Schleifscheibenaufsatz 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 is provided with an abrasive coating or can be equipped with sanding paper and can therefore 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 Verschlüsse erlauben ein schnelles Auswechseln des Schleifscheibenaufsatzes. 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 such that a bayonet or clamp closure is provided as the fastening device. Such closures allow a quick replacement of the grinding wheel attachment. According to the innovation, the grinding wheel can be designed such that the fastening device is designed for left- and right-handed 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 processing, which allows targeted machining of small objects.
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 such that a plurality of fixed or rotating grinding wheels are connected to one another via a multi-armed device, rotating about a common axis, are used for grinding. This is particularly useful for the uniform processing of large areas.
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 Material- stärke 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 such that the material thickness of the grinding wheel attachment is at most 30% of the maximum material thickness of the main grinding wheel body. This significantly reduces the costs of manufacture and disposal.
