Abstract
Description
Die vorliegende Erfindung betrifft ein Schneidwerkzeug zur spanenden Bearbeitung von Metallen oder dergleichen mit einer Schneide und einem Spanbrecher und einer dazwischen angeordneten Spanfläche, wobei die Schneide und die Spanfläche und/oder der Spanbrecher aus Diamant oder kubischem Bornitrid bestehen.The The present invention relates to a cutting tool for cutting Processing of metals or the like with a cutting edge and a chip breaker and a clamping surface arranged therebetween, wherein the cutting edge and the cutting surface and / or the chipbreaker made of diamond or cubic boron nitride.
Gattungsgemäße Schneidwerkzeuge werden zum Beispiel in Form von so genannten Schneidplatten für Fräseinrichtungen oder dergleichen verwendet. Häufig ist dabei vorgesehen, dass die Schneidplatten, vorzugsweise mittels Verschraubung, auswechselbar an einem Grundkörper der Fräseinrichtung angeordnet sind. Im Betrieb wird der Span von der Schneide vom zu bearbeitenden Werkstück, welches in der Regel aus Metall besteht, abgehoben und gleitet dann an der Spanfläche entlang zu einem Spanbrecher. Dieser dient im Wesentlichen dazu, den Span vom Schneidwerkzeug wieder zu lösen und umzulenken. Bei gattungsgemäßen bisher verwendeten Schneidwerkzeugen aus Diamant oder kubischem Bornitrid kommt es häufig zum Verkleben des Spans auf der Spanfläche aufgrund zu hoher Wärmeentwicklung. Darüber hinaus besteht das Problem, dass der vom Spanbrecher abgelöste Span oft in nicht gewünschte Richtungen geleitet wird.Generic cutting tools are for example in the form of so-called inserts for milling or the like is used. Often is provided that the inserts, preferably by means of Screw, interchangeable with a body of the milling device are arranged. In operation, the chip is from the cutting edge of the workpiece to be machined, which usually made of metal, lifted off and then slides on the clamping surface along to a chipbreaker. This essentially serves to loosen and deflect the chip from the cutting tool again. In generic used previously Cutting tools made of diamond or cubic boron nitride are involved often for bonding the chip on the chip surface due to excessive heat development. About that There is also the problem that the chip detached from the chip breaker often in unwanted Directions.
Aufgabe der Erfindung ist es, ein gattungsgemäßes Schneidwerkzeug dahingehend zu verbessern, dass diese Probleme nicht mehr auftreten.task The invention is to a generic cutting tool to the effect to improve that these problems no longer occur.
Dies wird erreicht, indem der Spanbrecher vorgeschobene Bereiche und zurückgezogene Bereiche aufweist und/oder die Spanfläche erhöhte Bereiche und vertiefte Bereiche aufweist.This is achieved by the chipbreaker advanced areas and withdrawn Has areas and / or the chip surface raised areas and recessed Has areas.
Durch die erhöhten bzw. vertieften Bereich in der Spanfläche kommt der mittels der Schneide abgehobene Span nicht mehr vollflächig zur Auflage, wodurch die sich im Kontaktbereich zwischen Spanfläche und abgehobenem Span entwickelnde Reibungswärme deutlich reduziert und ein Verkleben des Spans verhindert ist. Die vorgeschobenen und zurückgezogenen Bereiche des Spanbrechers bilden ein Profil, welches den auf den Spanbrecher auftreffenden Span in eine definierte Richtung umlenkt.By the raised or recessed area in the clamping surface comes by means of the cutting edge lifted span no longer over the entire surface to the support, causing the developing in the contact area between rake surface and lifted chip frictional heat significantly reduced and sticking of the chip is prevented. The advanced and withdrawn Areas of the chip breaker form a profile, which on the Chipbreaker impinging chip deflects in a defined direction.
Die Wahl des Materials aus dem die Schneide, der Spanbrecher und die Spanfläche ausgebildet sind, erfolgt in Abhängigkeit des zu bearbeitenden Werkstücks. So bieten sich Schneidwerkzeuge aus kubischem Bornitrid vor allem für die Bearbeitung von kohlenstoffhaltigen Eisenmetallen wie zum Beispiel Stahl an. Sollen Nicht-Eisen-Metalle wie Aluminium, Kupfer und dergleichen bearbeitet werden, so sind Diamantarten wie zum Beispiel polykristalliner Diamant oder CVD (Chemical Vapour Deposition) – Dickfilm – Diamant in der Regel zu bevorzugen. Es ist aber auch möglich, monokristallinen Diamant zu verwenden.The Choice of material from the cutting edge, the chipbreaker and the clamping surface are formed, takes place in dependence of the workpiece to be machined. For example, cutting tools made of cubic boron nitride are particularly suitable for the Machining of carbonaceous ferrous metals such as steel at. Should non-ferrous metals such as aluminum, copper and the like are processed, so are diamond species such as polycrystalline Diamond or CVD (Chemical Vapor Deposition) - Thick Film - Diamond is usually preferred. But it is also possible to use monocrystalline diamond.
Eine besonders bevorzugte Ausgestaltungsform sieht vor, dass der Spanbrecher und/oder die Spanfläche zumindest bereichsweise wellenförmig ausgebildet sind.A Particularly preferred embodiment provides that the chipbreaker and / or the chip surface at least partially wavy are.
