In the past, CEREC terminology has always referred to the cutting process as "milling" . However, the diamond burs (ex. 12, 12s, 20) actually use a grinding process to grind away the block material. The carbide and zirconia burs (Shaper 25rz, Shaper 25, finisher 10) use a literal milling process to cut and slice the material.

The confusion is understandable, considering those grinding with a large-grit wheel remove a lot of metal quickly and in so doing leave a "finish" of very deep scratches. But in grinding, scratches are just the aftereffect; quick material removal is the goal, especially when working with heat-sensitive metal like stainless steel.
