摘要： A method of high-speed turning of metal using a cutting tool insert for turning of steel. The cutting tool insert includes a (006) textured α-Al2O3 coated cemented carbide grade. The cemented carbide body has 4.5-6.5 wt-% Co and 3-10 wt-% cubic carbide forming metals and an S-value of 0.77-0.92 and a coercivity of 10-20 kA/m. The α-Al2O3 layer has a thickness ranging from 7 to 12 μm and is composed of columnar grains having a length/width ratio from 2 to 12 and is deposited on an MTCVD Ti(C,N) layer having a thickness from 4 to 12 μm. The alumina layer is characterised by a pronounced (006) growth texture. The alumina layer is the uppermost layer and is wet-blasted having an Ra value of less than 1 μm, giving the tool a black and shiny appearance.
