for higher precision, stable assembly and longer tool life continues to increase. The demand brings a great challenges for mold and stamping die manufacturing. As core functional components of tooling systems, punches and inserts directly influence cutting quality, dimensional consistency, as well as overall die performance. Among many machining methods, PG (Optical Profile) Grinding plays a vital role in achieving the precision required for these components. Accurate Profile Geometry for Reliable Tooling Performance Precise Radius Control and Clean Transitions In tooling performance, Radius geometry is very critical. However, it&#8217;s often underestimated. As a result, stress concentration, premature chipping, or fitting issues during assembly happen.
