Zero Rework on High-Complexity Crown via Wax Casting & 1mm Tooling
By casting the ultra-thin crown in wax to prevent breakage and using 1–3 mm tools with Hypermill to machine fine details like the 'Break Forest relief' and gem settings, the team eliminated rework on a high-complexity part. Siemens Sinumerik’s simultaneous turning and milling on a dental-grade SIMT PI5 machine delivered the surface quality demanded by premium manufacturing standards.
“We see rework elimination on high-mix, low-volume precision parts as a direct P&L lever—avoiding even 5–10 scrapped crowns per batch can save $50K+ annually in premium manufacturing.”
