Influence of Different Grades of CBN Inserts on Cutting ...

It can be observed from the given Figure 4 b that, the CBN-II inserts wear out due to the erosion of the CBN particle form the CBN matrix. CBN-II tools are the metallic binders-based substrate, having lower bonding strength. Due to the lower strength between CBN particles and binders, CBN particles plucked out from the substrate.
