摘要: A coated cemented carbide cutting tool (indexable inserts) for the wet or dry milling, particularly at high cutting speeds, of stainless steels of different composition and microstructure, but also for the milling of non-stainless steels such as low carbon steels and low and medium alloyed steels is disclosed. The coated WC−Co based cemented carbide insert includes a specific composition range of WC+Co without any addition of cubic carbides by a low W-alloyed Co binder and by a narrow range defined average WC grainsize, and a hard and wear resistant coating including a multilayered structure of sublayers of the composition (TixAl1−x)N with repeated variation of the Ti/Al ratio.

摘要: A coated turning insert particularly useful for dry and wet machining in low and medium alloyed steels, stainless steels, with or without raw surface zones under severe conditions such as vibrations, long overhang and recutting of chips. The insert is characterized by a WC--Co cemented carbide with a low content of cubic carbides and a rather low W-alloyed binder phase and a coating including an innermost layer of TiC.sub.x N.sub.y O.sub.z with columnar grains and a top layer of TiN and an intermediate layer of .kappa.-Al.sub.2 O.sub.3. The layers are deposited by using CVD-methods.
