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.
Unsure whether to specify lapping, polishing or ultra precision machining? Compare surface finish, flatness and geometry to choose the right process for precision optical parts.
Learn how custom optical component manufacturing turns drawings into finished parts through precision machining, optical polishing, lapping, and QC.
Optical polishing vs lapping: learn how each precision process works, the flatness and surface finish each achieves, and when to choose one for your part.
Optical lapping achieves flatness to 1 µm (±1 µm) at YISHUN; polishing extends it to 0.1 µm. Learn what affects achievable flatness and how to specify it in your RFQ.
Surface roughness controls how light transmits, reflects, and scatters in optics. Learn Ra vs RMS, roughness targets by material, and how precision optical polishing achieves them.
Ultra precision machining achieves tight tolerances and fine surface finishes by controlling not one variable, but an entire chain of potential errors. Machine motion accuracy, spindle behavior, cutti
