Industry Context & Processing Challenges: Case-hardened transmission gears and shafts (20MnCr5, hardened to 58-62 HRC) require hard turning of bearing seats and gear faces after heat treatment, replacing costly grinding operations where feasible.
Technical Requirements: IT-grade dimensional accuracy, surface finishes suitable for bearing seats, and minimal white-layer formation on hardened surfaces.
ZWH Tooling Solutions & Value: ZWH CBN hard-turning inserts with optimized edge preparations enable replace-grinding hard turning of gear faces and shaft seats, achieving grinding-class surface finishes while cutting cycle times and cost per part.
