Is it really worth it to use a CBN wheel?

A shop is grinding hardened steel, and periodically switches between a CBN wheel and an aluminum-oxide wheel. Given that the shop is getting pretty much the same material removal rate, surface finish and cycle times with both wheels, the shop is beginning to wonder if it's really worth it to use a CBN wheel.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, responds in the 45th episode of the video series.

About the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.
