A COATED CUTTING TOOL INSERT OF CEMENTED CARBIDE AND A METHOD FOR THE PRODUCTION THEREOF |
摘要 |
The present invention relates to a CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 10-300 MPa and an ±-Al 2 O 3 -layer with a high surface smoothness of <0.1 µm as measured by AFM-technique. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry consisting of F80 grits of Al 2 O 3 followed by a second wet blasting treatment with a slurry of F320 grits of Al 2 O 3 . |
