Match with Xiaomi Watch, Walker Fennel lens mold ultra-precision mirror processing
Maximum processing range 650mm*300mm
Face Pv precision 0.15um, roughness Ra0.005um




A UK medical optics customer approached YISHUN to verify our capability for small high-accuracy inserts requiring tolerances up to 0.002 mm and Ra 10 nm optical surfaces without polishing. This case shows how we evaluated the machining, metrology and lead-time risks before the project moved forward.

Burrs form at every machined edge and hurt sealing, fit and optics. Learn what causes micro burrs in ultra precision machining and how tooling, cutting strategy and deburring control them.

Surface finish decides how ultra precision machined parts seal, slide and perform optically. Learn how to specify Ra, process route and measurement.

Learn why temperature control decides whether ultra precision machining holds ±0.5 μm tolerances and Ra 1 nm finishes, plus the thermal questions to ask suppliers.
