A mirror finish does not always mean a precise optical mold insert. Learn how surface finish and form accuracy work together for better results.
Complex inner holes can be difficult to machine and polish without changing their geometry. Learn how YISHUN Optical evaluates oil-wire EDM, precision machining and inspection to control internal profiles and surface quality.
A smooth mirror finish does not guarantee accurate freeform geometry. Explore how precision machining, controlled polishing and suitable inspection help protect critical optical mold insert surfaces.
Small precision parts leave little room for error. Learn how tool control, geometry, finishing and inspection work together to maintain micro-scale accuracy.
Achieving a high-precision surface finish requires balancing mechanical shear, chemical removal rates, and contact stress distribution. In precision optical mirror polishing, components frequently pas
When precision optical mold inserts deviate from their nominal CAD models, the root cause is rarely a single toolpath error. In non-rotationally symmetric and steep aspheric geometries, physical parts
An optical mold core can display a flawless, mirror-like reflection to the naked eye while still producing plastic lenses plagued by wide-angle haze, contrast loss, and diffraction flares. Visual brig
Narrow grooves and small cavities create challenges in tool access, rigidity and finishing. This article explains how precision milling and mirror EDM can work together to achieve stable mirror surfaces and accurate geometry.
Right-angle mold inserts require careful process selection to maintain corner accuracy, surface quality and geometry consistency. This article explains when CNC mirror machining or mirror EDM is more suitable for precision cavities.
