Description

Verfahren zum Herstellen der Bohrung in einem Ziehstein Es ist bekannt, Ziehsteine und zwar insbesondere auch solche aus Diamant mit Hilfe eines Laserstrahles zu bohren. Dabei ergibt sich gegen- über den üblichen Bohrverfahren eine ganz wesentliche Zeitersparnis. Bohrt man einen Diamant-Ziehstein mit Hilfe eines fokussierten Laser- strahles, so hat die entstehende Bohrung in ihrem oberen Teil die Form eines zchlanken Konus an den sich der ebenfalls leicht konusförmige Ziehkanal anschließt. Ein fertig bearbeiteter Ziehstein muß jedoch einen weiten trichterförmigen Einlauf, die sogenannte Schüssel aufweisen, an den sich die Vorbohrung, in der der Übergang zum Verformungsteil gebildet wird und die Feinbohrung d. h. das eigentliche Verformungsteil anschließt. An den Verformurgsteil schließt sich die sogenannte Gegenbohrurig d.h. eine Bohrung relativ großen Durchmessers an.Method for producing the bore in a drawing die It is known to drill drawing dies, in particular also those made of diamond, with the aid of a laser beam. Compared to the usual drilling methods, this results in a very substantial time saving. If you drill a diamond drawing die with the help of a focused laser beam, the resulting hole has the shape of a slender cone in its upper part, to which the slightly conical drawing channel adjoins. A finished drawing die must, however, have a wide funnel-shaped inlet, the so-called bowl, to which the pilot hole, in which the transition to the deformation part is formed, and the fine bore, ie the actual deformation part, are connected. The so-called Gegenbohrurig, ie a hole with a relatively large diameter, is attached to the deforming part.

Auch bei Diamant-Ziehsteinen, welche mit Hilfe des Laserstrahles gebohrt wurden, mußte bisher sowohl die Schüssel als auch die Gegenbohrung nach herkömmlichen Verfahren hergestellt werden. Der Zeitaufwand In the case of diamond drawing dies, which were drilled with the aid of the laser beam, both the bowl and the counterbore had to be produced according to conventional methods. The time required
