    摘要： A cutting tool insert has a cermet body with a Co and/or Ni binder phase and a coating deposited as monolayer or as multiple and/or alternating layers of carbide, nitride or oxide. The coating has a thickness of 21-50 μm, when the inserts have a flat rake face, without or with simple chipbreakers and a Co binder phase, or has a thickness of 10-50 μm, when the inserts have a rake face land with a width of 100-300 μm with an angle of 10-25° to the rake face and a Co and/or Ni binder phase. The cermet body has more than 50 vol. % Ti-based carbonitride and less than 15 wt % and more than 6 wt % Co and/or Ni binder phase and a hardness of >1650 HV3. The disclosure also relates to the use of the coated cutting tool insert for the machining of cast iron work pieces.

    摘要： The present invention relates to coated cutting tool inserts particularly useful for heavy roughing turning operations of very large steel components, such as drive shafts for ships and shafts for wind power plants. The inserts are large with an iC, inscribed circle diameter, of greater than or equal to about 19 mm and a thickness of greater than or equal to about 6 mm with a composition of from about 5 to about 10 wt-% Co, from about 5 to about 12 wt-% cubic carbides or carbonitrides of the metals Ti, Ta and/or Nb, and balance WC with a stratified binder phase enriched surface zone from about 15 to about 40 μm thick. The inserts have an edge rounding before coating of 35-95 μm. The coating comprises a first, innermost layer of TiCxNyOz and a total thickness from about 0.1 to about 1.5 μm, a second layer of TiCxNy with a thickness of from about 4.5 to about 9.5 μm with columnar grains, a third layer of TiCxNyOz with a thickness of from about 0.3 to about 1.5 μm, a fourth layer of a smooth α-Al2O3 with a thickness of from about 4.5 to about 9.5 μm and, a from about 0.1 to about 2 μm thick colored top layer, preferably TiN or ZrN, on the clearance sides. The invention also relates to the method of making such inserts and the use thereof for heavy roughing turning operations of very large steel components.
