Claims (4)
- Verfahren zum Herstellen eines Abrasivelementes (2), aus einer Schneidstoffe (6) aufweisenden Sintermetallmatrix (4), bei dem die Schneidstoffe (6) in die Sintermetallmatrix (4) eingebunden bzw. eingebettet werden und eine Anschnittfläche (8) an der mit den Schneidstoffen (6) versehenen Sintermetallmatrix (4) durch eine Wasserstrahlbehandlung oder durch ein Wasserstrahlschneidverfahren hergestellt wird, dadurch gekennzeichnet, dass die Schneidstoffe (6) aufweisende Sintermetallmatrix (4) durch einen Trennschnitt (S1, S2) mittels des Wasserstrahlschneidverfahrens in zwei Abrasivelemente (2, 2', 11, 11') mit komplementären Anschnittflächen (8, 10, 14, 16) getrennt wird.
- Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass der Trennschnitt (S2) wellenförmig durchgeführt wird zur Erzeugung von wellenförmigen Anschnittflächen (14, 16).
- Verfahren nach Anspruch 1 , dadurch gekennzeichnet, dass die Anschnittfläche (8, 10) eben ausgebildet wird.
- Verfahren nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass in dem beim Wasserstrahlschneidverfahren verwendeten Wasserstrahl Abrasivstoffe enthalten sind.
