hello.  i'm a 3rd year materials engineering student at cal poly san
luis obispo.  i've got some cobalt discs mounted in 1-1/4" epoxy and a
leco ss 2000 autopolisher.  i also have leco cameo platinum 1, 2, and x
discs as well as a leco silver cameo disc.  i'm trying to grind the
discs down until i hit a target on the face of the disc.  i've got all
the documentation that came with the autopolisher, as well as a book of
recommended grinding/polishing procedures, but neither book has
anything to say about working with cobalt.  does anyone have any
suggestions?
