Release Date： 2026-10-26
- Industry Context & Processing Challenges: Aluminum die-casting mold cores (H13, STAVAX) hardened to 52–60 HRC traditionally require slow EDM processing. Direct hard milling replaces EDM but demands heat-resistant tools.
- Technical Requirements: Direct hard milling surface finish Ra<0.2 μm, eliminating secondary EDM polishing.
- ZWH Tooling Solutions & Value: ZWH nano-composite coated micro-grain carbide mills enable high-speed trochoidal hard milling, delivering fine cavity surface finishes directly on hardened steel.
