Title (EN) METHOD OF MACHINING TI, TI-ALLOYS AND NI-BASED ALLOYS
(FR) PROCÉDÉ D'USINAGE DE TI, D'ALLIAGES DE TI ET D'ALLIAGES À BASE DE NI
Abstract:
(EN) The invention relates to the use of cryogenic coolant in a machining operation in Ti, Ti- alloys or Ni-alloys together with a cutting tool comprising a cemented carbide substrate with a gradient surface zone with a thickness of between 50-400 μm. The cemented carbide substrate has a binder phase gradient with the lowest binder phase content in the outermost part of the gradient surface zone and the cemented carbide comprises graphite. The invention leads to a significantly prolonged tool life.
(FR) L'invention concerne l'utilisation d'un réfrigérant cryogénique dans une opération d'usinage de Ti, d'alliages de Ti ou d'alliages de Ni conjointement avec un outil de coupe comprenant un substrat de carbure cémenté ayant une zone de surface de gradient d'une épaisseur comprise entre 50 et 400 µm. Le substrat de carbure cémenté présente un gradient de phase liante ayant le contenu de phase liante le plus bas dans la partie la plus à l'extérieur de la zone de surface de gradient, et le carbure cémenté comprend du graphite. L'invention permet de prolonger considérablement la durée de vie de l'outil.
