Definitions

  • the present invention relates to a coated cemented carbide cutting tool insert particularly useful for wet and dry machining, preferably milling, of low and medium alloyed steels and stainless steels, with raw surfaces such as cast skin, forged skin, hot or cold rolled skin or pre-machined surfaces.
  • the coated cemented carbide insert must be based on a tough carbide substrate and have a coating with excellent adhesion.
  • the adhesive wear is generally the dominating wear type.
  • CVD- or PVD-coatings have to be used.
  • Measures can be taken to improve or optimize cutting performance with respect to a specific wear type. However, very often such measures will have a negative effect on other wear properties.
  • Comb crack formation can be reduced by lowering the binder phase content.
  • low binder content will lower the toughness properties of the cutting inserts which is far from desirable.
  • U.S. Pat. No. 6,062,776 discloses a coated cutting tool insert particularly useful for milling in low and medium alloyed steel with or without raw surface zones during wet or dry conditions.
  • the insert is characterized by WC-Co cemented carbide with a low content of cubic carbides and a highly W-alloyed binder phase, a coating including an innermost layer of TiC x N y O z with columnar grains and a layer of ⁇ -Al 2 O 3 with a top layer of TiN.
  • U.S. Pat. No. 6,406,224 discloses a coated cutting tool insert also particularly useful for milling of alloyed steel with or without abrasive surface zones at high cutting speeds.

  • the insert is characterized by having a straight WC-Co cemented carbide substrate and a coating consisting of a layer of TiC x N y O z with columnar grains and a top layer of fine grained textured ⁇ -Al 2 O 3 .
  • Swedish patent application 0500435-3 discloses a coated cutting tool insert suitable for machining of metals by turning, milling, drilling or by similar chip forming machining methods.
  • the tool insert is particularly useful for interrupted toughness demanding cutting operations.
  • U.S. Pat. No. 6,200,271 disclose a coated turning insert particularly useful for turning in stainless steel.
  • the insert is characterised by WC-Co-based cemented carbide substrate having a highly W-alloyed Co-binder phase and a coating including an innermost layer of TiC x N y O z with columnar grains and a top layer of TiN and an inner layer of fine grained ⁇ -Al 2 O 3 .
  • the inventors have after carrying out a lot of experiments and extensive testing at tool users on the market surprisingly found that by combining a number specific features an improved cutting tool insert, preferably for milling, can be obtained.
  • the combined features are: a specific cemented carbide composition, a certain WC grain size, alloyed binder phase, an inner coating consisting of a number of defined layers and a smooth top rake face layer of ⁇ -Al 2 O 3 .
  • the insert has improved cutting performance in low and medium alloyed steel, with or without raw surface zones preferably under stable conditions in both wet and dry machining. It is also surprising that the invented cutting tool insert also works well in stainless steel.

  • the cemented carbide insert is at least partly coated with a 4.1-6.9 ⁇ m thick coating including at least three layers of TiC x N y O z .
  • the three layers form an inner coating with an ⁇ -Al 2 O 3 -layer as the outer layer at least on the rake face.

  • the TiC x N y O z -layers having a total thickness of 1.9-3.6 ⁇ m comprise:
  • an additional 0.1-1 ⁇ m coloured layer is deposited on top of the ⁇ -Al 2 O 3 -layer preferably of TiN, TiCN, TiC, ZrN or HfN preferably using CVD technique prior to the blasting treatment.
  • an additional 0.1-1 ⁇ m coloured top layer is deposited at least at the flank faces preferably of TiN, TiCN, TiC, ZrN or HfN using CVD- or PVD-technique, preferably using CVD technique.
  • the present invention also relates to the use of an insert according to above for wet and dry machining, preferably milling, of low and medium alloyed steels and stainless steels, with raw surfaces such as cast skin, forged skin, hot or cold rolled skin or pre-machined surfaces at cutting speeds and feed rates according to following table:

Depth of cut: 2 mm Insert-style: R245-12T3M-PM Note: 1 insert, wet, very toughness demanding due to heavy chip load at exit of the milling cutter.
