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.
