Hard Turning

Thirty-five years ago, only 5% of mold components were recut after hardening. Today, hard turning is done to 85% of all inserts.

Tool steel parts hardened 44-68 RC can be hard turned with surface finishes of 15-20 RMS and tolerances of ±.0002". Because of the improved surface finish, interchangeable parts with sharp parting line edges and molding area contours are produced routinely, resulting in more consistent parts and less polishing time.
