Ceramic or CBN inserts for cutting of cast iron above 1000m/min line speed? Both ceramic tools and CBN tools could provide solutions for difficult to machine materials. However, how to apply suitable tools for different applications lies in several factors. Such as, hardness, materials, cutting conditions (continuous, semi-interrupt or heavy interrupt), and machining type (turning or milling).

Although CBN belongs to the ceramic category in materials science, there is a big difference between CBN, SIN, and AL2O3. The ceramic inserts are not as good as CBN inserts in toughness and hardness.

Therefore, if the working conditions such as hardness less than HRC50, small AP,
