I can tell by the pattern. My father used to own a machine shop that had numerous Blanchard grinders. I was Blanchard grinding when I was 15 yrs old. We used to grind brake rotors for Paul Newman and Bob Sharp racing. They liked the grind pattern and the close tolerance. Not to many places Blanchard grinding these days.
