Werkzeuge mit Schneidflächen aus oxydkeramischen Massen
EMI1.1
Vorteilhaft ist das Löten bei gleichzeitiger
Anwendung von Druck vorzunehmen.
Durch diesen kompliziert erscheinenden Auf- bau des Werkzeuges wird erst eine einwandfreie allseitige Fassung von vierkantigen Plättchen ermöglicht, u. zw. besser als dies durch Aus- arbeiten der Höhlung an einem Stücke möglich wäre, da nunmehr ein einwandfreies Passen an allen Plättchenflächen gewährleistet ist. Mit Hilfe der modernen Lötverfahren bereitet auch das
Löten der verhältnismässig grossen Flächen keine
Schwierigkeiten.
Man erkennt nach dem Löten, dass die ver- bindende Kupferschicht sich nicht nur zwischen den Stahlteilen befindet, sondern auch zwischen
Stahl und keramischen Schneidwerkstoff. Es dürfte hiebei zwar keine Lötung im üblichen
Sinne zwischen dem keramischen Werkstoff und dem Halter eintreten, doch ist die Einbettung eine so vollkommene, dass sie einer Lötung mit Metallen gleichwertig ist.
Durch die allseitige satte Fassung ist das Schneidplättchen nun so geschützt, dass auch empfindliche Werkstoffe, z. B. oxydkeramische Schneidwerkstoffe, erfolgreich angewandt werden können. Die mehrteilige Ausführung des Halters kommt vor allem für Drehwerkzeuge mit vierkantigen Schneidplättchen in Frage. Es ist aber auch möglich, sinngemäss andere Werkzeuge, wie Fräser, Tiefbohrer u. dgl. zusammenzubauen.
In manchen Fällen ist auch das Verkitten der einzelnen Teile, z. B. mit einem hochwertigen Zement, wie Zahnzement dem Löten gleichwertig.
Auch beim Verkitten ist es vorteilhaft, den Erhärtungsvorgang bei gleichzeitiger Anwendung von Druck vor sich gehen zu lassen.
Selbstverständlich können neben oxydkeramischen Arbeitsteilen Hartmetalle in gleicher Weise in mehrteilige Halter eingesetzt werden.

Tools with cutting surfaces made of oxide ceramic materials
EMI1.1
Soldering at the same time is advantageous
Apply pressure.
Because of this construction of the tool, which appears to be complicated, a perfect all-round setting of small square plates is made possible, u. or better than would be possible by working out the cavity on one piece, since a perfect fit is now guaranteed on all plate surfaces. With the help of modern soldering processes, that too
No soldering of the relatively large areas
Trouble.
After soldering, you can see that the connecting copper layer is not only between the steel parts, but also between them
Steel and ceramic cutting material. There should be no soldering in the usual way
Senses occur between the ceramic material and the holder, but the embedding is so perfect that it is equivalent to soldering with metals.
Thanks to the full version on all sides, the cutting tip is now protected in such a way that even sensitive materials, e.g. B. oxide ceramic cutting materials can be used successfully. The multi-part design of the holder is particularly suitable for turning tools with square cutting tips. But it is also possible to use other tools, such as milling cutters, deep drills and the like. to assemble.
In some cases it is also possible to cement the individual parts, e.g. B. with a high quality cement, such as dental cement equivalent to soldering.
When cementing, too, it is advantageous to allow the hardening process to proceed while applying pressure.
Of course, in addition to oxide ceramic working parts, hard metals can be used in the same way in multi-part holders.
