In that regard, on the DE 197 03 175 C2 referenced, according to which a thermoplastic slip is used for the production of a ceramic or powder metallurgical component.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zur Herstellung eines Werkzeugs, sowie ein Verfahren zur Herstellung eines arbeitenden Teils aus Diamant und/oder CBN oder dieses enthaltend zur Verfügung zu stellen, das auch bei komplizierten Geometrien hochpräzise und reproduzierbar herstellbar ist.The present invention is based on the object to provide a method for producing a tool, as well as a method for producing a working part of diamond and / or CBN containing this, which can be produced with high precision and reproducible even in complicated geometries.

Zur Lösung der Aufgabe sieht die Erfindung im Wesentlichen vor, dass das arbeitende Teil durch ein generatives Fertigungsverfahren von auf den Körper aufgetragenem schütt- und/oder fließfähigen Material bestehend aus oder enthaltend Matrixpartikel aus der Gruppe Metallpartikel, Keramikpartikel sowie aus Diamant und/oder CBN bestehenden Partikeln hergestellt wird. Dabei kann das schüttfähige Material ein kohäsives oder kohäsionsloses, also freifließendes Schüttgut sein.To solve the problem, the invention essentially provides that the working part by a generative manufacturing process applied to the body pourable and / or flowable material consisting of or containing matrix particles from the group of metal particles, ceramic particles and diamond and / or CBN existing Particles is produced. The pourable material can be a cohesive or cohesion-free, ie free-flowing bulk material.

Vorzugsweise wird vorgeschlagen, dass das Teil durch Lasersintern oder -schmelzen hergestellt wird. Dabei kann das schütt- und/oder fließfähige Material schichtweise auf den Körper aufgetragen oder über eine Düse dem Bereich des Körpers zugeführt werden, auf den der Laserstrahl trifft.It is preferably proposed that the part is produced by laser sintering or melting. In this case, the pourable and / or flowable material can be applied in layers to the body or fed via a nozzle to the region of the body, which is hit by the laser beam.

Erfindungsgemäß wird ein arbeitendes Teil mit Diamant und/oder CBN in einem generativen Fertigungsverfahren hergestellt, so dass auch arbeitende Teile wie Schneiden oder Schneidkörper hoher geometrischer Komplexität zur Verfügung stehen, die nach den herkömmlichen Verfahren nicht oder nur durch aufwendige und kostenträchtige Maßnahmen hergestellt werden können.According to the invention, a working part with diamond and / or CBN is produced in a generative manufacturing process, so that working parts such as cutting or cutting bodies of high geometric complexity are available, which can not be produced by conventional methods or only by consuming and costly measures.

Hierzu wird ein Pulver benutzt, das aus den Matrixpartikeln, insbesondere Metallpartikeln, und aus Partikeln aus Diamant und/oder CBN besteht.For this purpose, a powder is used which consists of the matrix particles, in particular metal particles, and of particles of diamond and / or CBN.

Insbesondere ist vorgesehen, dass die Diamant- oder CBN-Partikel in Form eines Granulats oder eines Pulvers mit den Matrixpartikeln vermischt werden. Dabei können die Diamant- bzw. CBN-Partikel eine Korngröße zwischen 0,1 μm und 6 μm oder mehr aufweisen, wobei die zahlenmäßig angegebene Korngröße für zumindest 50%, insbesondere für zumindest 70%, besonders bevorzugt für zumindest 90% der Diamant- oder CBN-Partikel gilt.In particular, it is provided that the diamond or CBN particles are mixed in the form of a granulate or a powder with the matrix particles. The diamond or CBN particles may have a particle size between 0.1 .mu.m and 6 .mu.m or more, wherein the number of grain sizes specified for at least 50%, in particular for at least 70%, particularly preferably for at least 90% of the diamond or CBN particles applies.

Die Größe der Diamant- bzw. CBN-Partikel muss derart sein, dass dann, wenn das aus den Matrixpartikeln und den Diamant- und/oder CBN-Partikeln bestehende Pulver mittels einer Düse aufgetragen wird, die Düse durchsetzt werden kann.The size of the diamond or CBN particles must be such that, when the powder consisting of the matrix particles and the diamond and / or CBN particles is applied by means of a nozzle, the nozzle can be penetrated.

Bei den Diamant- und/oder CBN-Partikeln kann es sich um solche handeln, die eine sortierte oder unsortierte Korngröße aufweisen.The diamond and / or CBN particles may be those which have a sorted or unsorted grain size.

Insbesondere ist vorgesehen, dass die Matrixpartikel, vorzugsweise die Metallpartikel eine mittlere Korngröße D50 zwischen 1 μm und 50 μm, vorzugsweise zwischen 10 μm und 20 μm, aufweisen. Als Material für die Metallpartikel kommt insbesondere Hartmetall in Frage. Als Keramikmaterialien kommen solche in Frage, die der durch den Laserstrahl hervorgerufenen Hitze standhalten. Beispielsweise ist Zirkonoxid zu nennen.In particular, it is provided that the matrix particles, preferably the metal particles have an average particle size D50 between 1 .mu.m and 50 .mu.m, preferably between 10 .mu.m and 20 .mu.m. As a material for the metal particles is in particular carbide in question. As ceramic materials are those in question, which withstand the heat caused by the laser beam. For example, zirconium oxide is mentioned.

Vorzugsweise sollte die Größe der Matrixpartikel der der Diamant- bzw. CBN-Partikel entsprechen.Preferably, the size of the matrix particles should correspond to that of the diamond or CBN particles.

Insbesondere sieht die Erfindung vor, dass das schütt- und/oder fließfähige Material schichtweise auf zumindest einen Bereich des Werkzeugkörpers aufgetragen wird, wobei sukzessiv jede Schicht einer zum lokalen Sintern oder Schmelzen führenden Energie eines Laserstrahls ausgesetzt wird, wobei die von der Energie beaufschlagten Bereiche die gewünschte Geometrie des Schneidkörpers bilden.In particular, the invention provides for the pourable and / or flowable material to be applied in layers to at least one region of the tool body, wherein each layer is successively exposed to an energy of a laser beam leading to local sintering or melting, wherein the energized areas form the desired geometry of the cutter body.

Alternativ ist vorgesehen, dass das schütt- und/oder fließfähige Material strahlförmig dem Körper zugeführt wird, wobei das schütt- bzw. fließfähige Material in den Bereich auf den Körper trifft, in dem dieser von dem Laserstrahl beaufschlagt wird.Alternatively, it is provided that the pourable and / or flowable material is supplied to the body in a jet shape, wherein the pourable or flowable material strikes the body in the region in which it is acted upon by the laser beam.

Ein Verfahren zur Herstellung eines arbeitenden Teils bestehend aus Diamant und/oder CBN oder dieses enthaltend zeichnet sich dadurch aus, dass das Teil durch ein generatives Fertigungsverfahren von aus schütt- und/oder fließfähigem Material – enthaltend oder bestehend aus Matrixpartikeln aus der Gruppe Metallpartikel, Keramikpartikel sowie aus Diamant und/oder CBN bestehenden Partikeln – hergestellt wird. Dabei können Verfahrensmaßnahmen zur Anwendung gelangen, wie diese zuvor erläutert worden sind.A method for producing a working part consisting of diamond and / or CBN or containing this is characterized in that the part by a generative manufacturing process of pourable and / or flowable material - containing or consisting of matrix particles from the group of metal particles, ceramic particles and diamond and / or CBN particles. In this case, procedural measures can be applied as they have been explained above.
