Abstract

A cutter wheel is partially or completely coated with a polycrystalline diamond layer. Preferred Features: The polycrystalline diamond layer is applied by CVD onto the untreated or modified surface of the wheel substrate or onto one or more interlayers. The crystalline morphology and/or orientation and/or the graphite carbon distribution of the polycrystalline diamond layer may be controlled by selection of process parameters during the wheel substrate pretreatment and the CVD coating process.

Description

Anwendungsgebietfield of use

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Stand der TechnikState of the art

Beim Zuschneiden von Glas werden durch Anritzen der Glasoberfläche Spannungen in das Glasvolumen eingebracht, die es ermöglichen das Glas an der so gekerbten Stelle zu zer­ teilen. Dazu werden seit langem verschiedene Werkzeuge verwendet. So gibt es geschliffe­ ne einkristalline Diamanten, die in einem Träger eingelassen werden. Des weiteren gibt es Schneidräder, z. B. aus Hartmetall oder Stahl, die mittels einer Vorrichtung über die Oberflä­ che gerollt werden. Einige weitere Möglichkeiten werden z. B. in Schriften des Deutschen Patentamtes dargelegt Offenlegungsschriften; DE 43 05 719 A1, DE 35 38 169 A1 und DE 31 46 180 A1; Gebrauchsmuster: G 83 19 850.4, G 89 11 530.9 und G 8507451.9.When cutting glass, tensions are created in the glass by scratching the glass surface Glass volume introduced, which allow the glass to be broken at the notched location divide. Various tools have long been used for this. So there is ground ne single-crystal diamonds, which are embedded in a carrier. Furthermore there is Cutting wheels, e.g. B. of hard metal or steel, which by means of a device on the surface be rolled. Some other options are e.g. B. in German writings Patent Office sets out disclosure documents; DE 43 05 719 A1, DE 35 38 169 A1 and DE 31 46 180 A1; Utility model: G 83 19 850.4, G 89 11 530.9 and G 8507451.9.

Nachteile des Standes der TechnikDisadvantages of the prior art

Geschliffene einkristalline Diamanten müssen zum einen relativ groß sein, weshalb sie sehr teuer sind. Um mit ihnen einen guten Schnitt zu erzielen, muß der Diamant zum anderen auch optimal zur Schnittrichtung angestellt werden, was verhältnismäßig aufwendig sein kann und bei einem Schnitt per Hand viel Fingerfertigkeit erfordert. Aus diesen Gründen ha­ ben sich in der Praxis an vielen Stellen Schneidräder aus Hartmetall oder Stahl durchge­ setzt. Da Glas aber ein sehr hartes und abrasiv wirkendes Material ist, unterliegen die Schneidräder einem hohen Verschleiß, was die Wartungsintervalle kurz hält und damit die Kosten erhöht. Auf Grund der relativ geringen Abmessungen der Schneidrader und wegen der für ihrer Bearbeitung verhältnismäßig hohen Härte, ist das Erstellen komplexer Schnei­ dengeometrien aufwendig.On the one hand, cut single-crystal diamonds must be relatively large, which is why they are very large are expensive. In order to achieve a good cut with them, the diamond must go to the other can also be optimally adjusted to the cutting direction, which can be relatively expensive can and requires a lot of dexterity when cutting by hand. For these reasons ha cutting wheels made of hard metal or steel are used in many places in practice puts. But since glass is a very hard and abrasive material, they are subject to Cutting wheels wear a lot, which keeps the maintenance intervals short and thus the Costs increased. Because of the relatively small dimensions of the cutting wheels and because The relatively high hardness for their processing is the creation of complex cuts complex geometries.

Aufgabe der ErfindungObject of the invention

Ziel der Erfindung ist es, das Verschleiß- und Schneidverhalten von Schneidräder zu verbes­ sern und verschiedene Schneidengeometrien einfacher zu erzeugen.The aim of the invention is to improve the wear and cutting behavior of cutting wheels and different cutting edge geometries easier to generate.

Lösung der AufgabeSolution of the task

Diese Aufgabe wird durch ein Werkzeug entsprechend den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a tool according to the features of claim 1 solved.

Vorteile der ErfindungAdvantages of the invention

Durch einen geringeren Verschleiß der Schneidräder wird ihre Haltbarkeit erhöht, somit wer­ den die Wartungsintervalle ausgedehnt und dadurch Kosten gesenkt. Durch die Beschich­ tung können andere Schneidengeometrien und Schneidkantenoberflächen einfacher erzeugt werden, die ein anderes Schneidverhalten und damit ein anderes Bruchverhalten bewirken können.Less wear on the cutting wheels increases their durability, thus who which extends the maintenance intervals and thereby reduces costs. Through the Beschich other cutting edge geometries and cutting edge surfaces can be created more easily that cause a different cutting behavior and thus a different breaking behavior can.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments

Die Beschichtung der Schneidräder kann dabei folgende Eigenschaften aufweisen: So kann die Diamantschicht über die gesamte oder nur auf Teilen der Schneidradoberfläche aufge­ bracht sein. Die Schneidkante kann vor und/oder nach der Beschichtung abgerundet oder scharfkantig sein. Die Diamantschichtstruktur kann von grobkristallin bis mikrokristallin aus­ geprägt sein, wobei die Ausrichtung der Diamantkristalle zum Substrat von <110<- bis <100<-Richtung variieren kann, und die Diamantkristalle Körper mit reinen {100}-, {110}- oder {111}-Flächen sein können, jedoch meist Mischkörper mit diesen Facetten bis hin zu Bort sind. Die Diamantschicht kann nachbehandelt (z. B. geschliffen, poliert, geläppt, geätzt usw.) oder nicht nachbehandelt werden. Die Eigenschaften, der in den drei letztgenannten Sätzen, können auf der gesamten Diamantschicht oder nur auf bestimmte Teilgebiete der Diamantschicht ausgedehnt sein.The coating of the cutting wheels can have the following properties: the diamond layer over all or only parts of the cutting wheel surface be brought. The cutting edge can be rounded off before and / or after the coating be sharp-edged. The diamond layer structure can range from coarsely crystalline to microcrystalline be shaped, with the alignment of the diamond crystals to the substrate from <110 <- to  <100 <direction can vary, and the diamond crystals body with pure {100} -, {110} - or {111} faces, but mostly mixed bodies with these facets up to Bort are. The diamond layer can be post-treated (e.g. ground, polished, lapped, etched etc.) or not treated afterwards. The properties of the latter three Sets can be on the entire diamond layer or only on certain sub-areas of the Diamond layer can be extended.
