Two CBN grades were used for the tools: 7015 and 7025.

Machining with CBN Inserts - Carbide Inserts | Cutting Tools

Alloy Steels with a hardness below 40 HRc are not generally machined using CBN inserts because other tool materials work as well or better and cost less. Soft materials often stick to PCBN cutting tools causing “build up” on the cutting edge. This results in poor surface finish and tool life.

hardened steel interrupted turning - practical machinist


Ceramics work by getting the material HOT and then wiping it away.. SO... Unlike with a carbide insert, you need MORE speed with an interrupted cut. You also need to BUILD the heat to start, either a ramp in, or start with a low feed to build the heat, then pick up the feed.
