             The rotor consists of many stacked plates of electric steel.

             Lamination sheets are used instead of a solid body to reduce
             current loss. The surface must be completely clean of chips,

             oil, water, dust or dirt, and coolant fluid cannot be used,
             only air. This is a challenge as a lot of heat is generated
             on the cutting area and the fragmented chips stick
             to the surface. Surface finish requirements for this

             interrupted turning operation remain strict.

             ISCAR has overcome these challenges by developing a

             combined tool with coolant holes both on top and bottom
             of the cutting edge to cool and blow away the chips. The
             two round inserts are positioned for semi-finish and finish

             operations, generating an Ra 1.9. surface quality.
