BN-K1 solid cbn inserts for rough machining cast iron rolls

BN-K1 solid cbn inserts for rough machining cast iron rolls Different rolls are made of different materials, so it has different hardness, the cutting tools also need to be different. For low hardness rolls, like ductile iron rolls, we often choose carbide insert, such as YG6 or YG6X. But when machining high hardness rolls, above HSD75, like chilled cast rolls (ICDP Rolls), Hi-Ni rolls, Hi-Cr rolls, HSS rolls, Semi-rolls, Ni-Cr-Mo Centrifugal Rolls, we need to choose cbn
