Electron Micrographs of New and Used Abrasives

Wed Feb 26, 2014 7:29 pm

I really liked this YouTube video which has a field engineer explaining many electron microscope pictures of new and used grinding wheels. I was surprised at how stringy swarf is from the abrasion process. Narrator said the high speed steel was approximately 60 HRC.
