Abstract

The exchangeable tools are provided with a defined cutting bit of ultra-hard cutting materials such as polycrystalline diamond, CVD and cubic boron nitrite, wherein the cutting bit for putting into use is sharpened by means of a laser and in the micro-range is smoother and sharper than a ground cutting bit.

Description

Extrem genaue und extrem scharfe Schneidkanten aus ultraharten Schneidstoffen.Extreme precise and extremely sharp cutting edges made of ultra-hard cutting materials.

Werkzeuge bisheriger Bau- und Herstellungsart mit definierter Schneide aus ultraharten Schneidstoffen wie polykristalliner Diamant, CVD und kubisches Bornitrit sind in Schärfe und Präzision durch Größe und Lage des eingepressten Korns eingeschränkt, solange das einzelne Korn nicht getrennt werden kann. Die Handelsüblichen geschliffenen Schneiden nach Stand der Technik haben folgende Einschränkungen:

  • 1. Die eingepressten Körnchen des ultraharten Schneidstoffes werden lediglich herausgetrennt.
  • 2. Die Schneiden sind bei der Herstellung im ständigen Kontakt und Wechselwirkung mit einem Schleifmaterial, das in etwa dieselbe Härte hat, was zwangsläufig zu hohen Schleifdrücken und starken Wechselwirkungen mit der Schneide zur Folge hat, und die Genauigkeit der Schneide einschränkt.
Tools of previous construction and production with a defined cutting edge of ultra-hard cutting materials such as polycrystalline diamond, CVD and cubic boron nitride are limited in sharpness and precision by size and position of the pressed grain, as long as the individual grain can not be separated. The commercially available ground cutters according to the prior art have the following limitations:
  • 1. The pressed-in grains of the ultra-hard cutting material are merely cut out.
  • 2. The blades are in constant contact with and interact with an abrasive material that has approximately the same hardness, which inevitably results in high grinding pressures and strong interactions with the blade, and limits the accuracy of the blade.

Die steigenden Ansprüche, insbesondere in der Metallzerspanung, erfordern jedoch immer schärfere Schneiden, immer härtere Schneiden, und immer komplexere Schneidengeometrien, die mit dem abrasiven Abtrag zur Zeit nicht herstellbar sind.The increasing demands, especially in metal cutting, but require ever sharper cutting, harder and harder Cutting, and increasingly complex cutting geometries, with the abrasive Removal currently can not be produced.

Mit der Laserbearbeitung wird erreicht, dass nunmehr eine weitaus höhere Schneidenschärfe erreicht werden kann, da der Laser in der Lage ist, ein gepresstes Diamant oder CBN Korn berührungslos zu trennen und das verbliebene getrennte Korn in der Bindematrix der Schneide zu halten.With The laser processing is achieved that now reaches a much higher cutting edge sharpness can be because the laser is capable of a pressed diamond or CBN grain contactless too and the remaining separated grain in the binding matrix of the Cutting edge.

Deshalb übertrifft die Qualität bezeichneten Schneidkanten den bisherigen Stand der Technik um ein Vielfaches hinsichtlich Schartigkeit, Ausbrüche und Genauigkeit. Dies bietet dem Anwender bestmögliche Oberflächenqualität der zerspanten Bauteile bei gleichzeitiger Steigerung der Werkzeugstandzeiten.That's why excels the quality designated cutting edges the prior art to a Much in terms of pungency, outbreaks and accuracy. This offers the best possible for the user Surface quality of the machined Components while increasing tool life.
