Description

Verfahren zur Herstellung von Schleif- und Schneidwerkzeugen, insbesondere für zahnärztliche Zwecke Bisher werden in der zahnärztlichen Praxis Schleifwerkzeuge verwendet, deren Schleifkörper aus massivem Schleifmaterial auf keramischem Wege hergestellt ist, oder solche, die aus einem Träger aus Kupfer mit einer darauf durch Einwalzen o. dgl. befestigten Schleifmittelschicht bestehen.Process for the production of grinding and cutting tools, in particular for dental purposes So far, grinding tools have been used in dental practice used, whose abrasive body is made of solid abrasive material in a ceramic way is made, or those made from a support made of copper with a through it Roll in o. The like. Fixed abrasive layer exist.

Die ersteren Schleifwerkzeuge haben den Nachteil, daß sie ihre Form beim Schleifen nach und nach verlieren, auch lassen sie sich wie auch die mit einem Schleifmittelträger aus Kupfer bestehenden Schleifwerkzeuge nicht für alle notwendigen Schleifarbeiten verwenden, insbesondere dort nicht, ,, wo Schleifkörper von sehr kleiner Form verlangt werden. Solche kleinen Schleif- und Schneidwerkzeuge erfordern einen .Schleifmittelträger aus hartem, widerstandsfähigem Material, damit sie sich beim Gebrauch nicht verbiegen.The former grinding tools have the disadvantage that they change their shape Gradually lose when grinding, they can also be used as well as with one Abrasive backing made of copper existing grinding tools are not necessary for all Do not use grinding work, especially where, where grinding tools are of great use small form are required. Such small grinding and cutting tools require an abrasive carrier made of hard, resilient material so that they can do not bend during use.

Das Verfahren nach der Erfindung bezweckt nun die Herstellung solcher widerstandsfähigen kleinen Schleif- und Schneidwerl@-zeuge auch unter Verwendung schon gebrauchsfertiger Werkzeuge, wie Bohrer, Fräser; Feilen u. dgl., mit denen es aber bisher nicht möglich war, harten Zahnschmelz oder Porzellan u. dgl. einwandfrei zu bearbeiten.The method according to the invention now aims to produce such Resistant small grinding and cutting tools also when using ready-to-use tools such as drills, milling cutters; Files and the like, with which but it was not previously possible to obtain hard enamel or porcelain and the like perfectly to edit.

Das Verfahren zum Herstellen solcher Schleif- und Schneidwerkzeuge besteht darin, daß ein aus hartem Metall, z.B. Eisen, Stahl oder gehärtetem Stahl, hergestellter Werkzeugkörper mit einer Weichmetallauflage versehen wird, die zur Einbettung des Schleifmittels, z. B. Diamant-, Silicium-, Carbidkorn o. dgl., dient und die auf galvanischem Wege oder durch ein Tauch-, Löt- oder Spritzverfahren auf den Werkzeugkörper aufgebracht wird. Die Befestigung der Schleifmittelkörnchen in dieser weichen Schicht erfolgt, wie bekannt, durch Einpressen, Einhämmern u. dgl. Auf die weiche Metallzwischenschicht wird nun eine härtere, Säure und Basen. widerstandsfähige Metallschicht auf galvanischem Wege oder durch ein Spritzverfahren aufgebracht, um hierdurch eine zusätzliche Befestigung der Schleifmittelschicht auf dem Werkzeugkörper zu erreichen und außerdem die weiche, das Schleifmittel tragende Metallschicht gegen äußere Einwirkungen bei Gebrauch, beim Reinigen und Sterilisieren des Werkzeuges besonders widerstandsfähig zu machen.The process of making such grinding and cutting tools consists in that a hard metal, e.g. iron, steel or hardened steel, Manufactured tool body is provided with a soft metal coating that is used for Embedding of the abrasive, e.g. B. diamond, silicon, carbide grain o. The like. Serves and that by galvanic means or by a dipping, soldering or spraying process the tool body is applied. The attachment of the abrasive grains in This soft layer takes place, as is known, by pressing in, hammering in and the like. A harder acid and base is now applied to the soft intermediate metal layer. resistant Metal layer applied by galvanic means or by a spraying process, in order to achieve an additional fastening of the abrasive layer on the tool body and also the soft metal layer carrying the abrasive against external influences during use, when cleaning and sterilizing the tool to make them particularly resistant.
