Episode: 107: Grinding, a pictorial odyssey

For twenty-five years I have been taking electron-microscope photos of grinding wheels, grinding grits, grinding swarf, ground workpieces and dressing diamonds. Why?

When I’m giving a course and flash a photo of grinding swarf, a dull grit in a grinding wheel or a worn diamond, people’s eyes pop out. Many have worked in grinding for 20 years or more but have never had the chance to visualize grinding up close. It changes their perspective — and helps them learn the material quicker and, consequently, improve their grinding.

The Grinding Doc video series returns

After a long hiatus due to the COVID-19 pandemic, the Grinding Doc video series on Cutting Tool Engineering's website resumes with a special two-hour episode about Cylindrical Master 2020, an Excel program developed by Dr. Jeffrey Badger, aka the Grinding Doc. The 105th episode of the Grinding Doc video series provides a detailed description of the Cylindrical Master program that Badger developed during the pandemic.
