Description

Schneidwerkzeuge für Körper aus. härtbaren Kunststoffen Es ist bekannt, Schnell:s.tahl und Hartmetall als Schneidwerkstoffe zu verwenden. Es wurde auch schon Sinterkorund als Schneidwerkstoff vorgeschlagen und insbesondere auf die Möglichkeit. dadurch einen Teil der hochlegierten Schneidwerkzeuge zu ersetzen, hingewiesen. Sinterkorund hat insbesondere bei härtbaren Kunstharzpreßmassen und ähnlichen. Kunstharzteilen gute Schneidleistungen ergeben, er hat aber den Nachteil. daß er mir sehr schwierig zu haltern und nur unter größten Vorsichtsmaßnahmen richtig nachzuschleifen ist.Cutting tools for bodies. hardenable plastics It is known Fast: s.tahl and carbide can be used as cutting materials. It was too Sintered corundum has already been proposed as a cutting material and in particular on the possibility. thereby replacing some of the high-alloy cutting tools. Sintered corundum is particularly useful in hardenable synthetic resin molding compounds and the like. Synthetic resin parts result in good cutting performance, but it has the disadvantage. that he is very difficult for me can only be held and sharpened correctly with the greatest possible precautionary measures.

Es wurde überraschenderweise gefunden, daß Sintereisen bzw. Sinterstahlkörper, die durchgreifend nitriert wurden und z. B. einen Stickstoffgehalt von 3 °lo und darüber aufweisen, trotz ihrer verhältnismäßig geringen Zugfestigkeit und noch vorhandenen Restporosität ausgezeichnet zum Schneiden bei härtbaren Kunstharzen und Stoffen ähnlicher Festigkeiten zu verwenden sind. Merkwürdigerweise zeigen diese nitrierten Sinterkörper bei Kunstharz bessere Schneidleistungen als Schnellstahl und manchmal sogar als Hartmetall, obwohl sie die Härte des Hartmetalls durchaus nicht erreichen. Es hängt dies vielleicht mit der Reibung des organischen Körpers auf den karbidhaltigen Werkstoffen und den nitridhaltigen andererseits zusammen.It was surprisingly found that sintered iron or sintered steel body, which were thoroughly nitrided and z. B. a nitrogen content of 3 ° lo and have about it, despite their relatively low tensile strength and still existing Residual porosity excellent for cutting hardenable synthetic resins and fabrics similar strengths are to be used. Strangely enough, these show nitrated Sintered bodies with synthetic resin have better cutting performance than high-speed steel and sometimes even as hard metal, although they by no means achieve the hardness of hard metal. Perhaps this is due to the friction of the organic body on the carbide-containing ones Materials and the nitride-containing on the other hand together.

Durch den erfindungsgemäßen Werkstoff kann eine. beträchtliche Einsparung an Legierungselementen gegenüber den bisherigen Schneidwerkstoffen erzielt werden. Ferner ist die Halterung einfach herzustellen, da der Sinterkörper vor dem Nitrieren gut zu löten ist und die Lötverbindung durch das Nitrieren nicht geschwächt wird. Auch lassen sich Schnpidwprkzeugp mit nitrierten Sinterstahlkörpern in üblicher Weise ordnungsgemäß nachschleifen.The material according to the invention can be a. considerable savings of alloy elements compared to the previous cutting materials achieved will. Furthermore, the holder is easy to manufacture because the sintered body before Nitriding is easy to solder and the soldering connection is not weakened by the nitriding will. Schnpidwprkzeugp with nitrided sintered steel bodies can also be used in the usual way Regrind properly.

Als Beispiel sei angeführt, daß eine Schneide aus gesintertem Weicheisen, nach dem Auflöten nitriert, beim Abdrehen - auf Teilen aus härtbaren Kunstharzen dem bisher dafür verwendeten Schnellstahl überlegen war.As an example it should be mentioned that a cutting edge made of sintered soft iron, Nitrided after soldering, when turning - on parts made of hardenable synthetic resins was superior to the high-speed steel previously used for this.
