Embodiment 1
[0057] A coated cutting tool according to one embodiment of the present invention was manufactured. First, by pressing the powder and sintering the compact, the following cemented carbide CNMG120408-PM substrate was produced with a composition of 7.5% by weight of Co and a balance of WC, an Hc value of 13 kA / m (using Foerster Koerzimat CS1.096, Hardness according to DIN IEC 60404-7) and HV3 = 15 GPa. Prior to coating deposition, the substrate edges were rounded to about 50 μm by wet blasting.
[0058] refer to figure 1 , a coating consisting of a first layer and a second layer is deposited on the substrate by CVD. The first layer is a Ti(C,N,O) layer with a total thickness of 10.3 μm consisting of the layer sequence 0.4 μm TiN, 9.1 μm MTCVD Ti(C,N), 0.2 μm HTCVD Ti(C,N) and 0.6 μm Ti(C,O) composition. The second layer is made of internal 4.5μmα-Al 2 o 3 layer, middle 2.5 μm (Al,Ti)(C,O) / TiN / Ti(C,O) layer and outer 6.8 μm α-Al 2 o 3 layered sandwich structure. Used in...
Embodiment 2
[0063] Coated cutting tools were manufactured according to Example 1, except that the wet blasting operation was different, where only the top blast was applied, see Figure 5 .
Embodiment 3
[0065] A cutting tool according to the prior art was manufactured as in Example 2 but without laser operation, comprising; CNMG120408-PM substrate with a composition of 7.5% by weight of Co and a balance of WC, 13 kA / Hc value of m (using Foerster Koerzimat CS1.096 according to DIN IEC 60404-7) and hardness of HV3 = 15GPa; and coating with 9 μm Ti(C,N) first layer and 4.5 μm α-Al 2 o 3 The second layer and Ti(C,N) colored layer. The top blasting operation removes the colored layer on the rake face.
