A wheel supplier urged a shop to use a 150 mesh grit wheel to put a 0.005" radius into a part, but when the shop went from its 80 mesh grit to the smaller grit the result was horrific chatter. In fact, the shop always gets chatter from small grit wheels. For some explanation, the shop wrote to Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, for the 36th 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 i Cutting Tool Engineering magazine, Badger routinely receives questions about grinding from shops all over the world.
