Stainless Steel Precision Casting Mirror-Polished Glass Fixtures Introduction Stainless steel precision casting mirror-polished glass fixtures represent the pinnacle of manufacturing technology for optical and precision engineering applications. These components combine advanced metallurgical techniques with superior surface finishing to create fixtures that meet the most demanding requirements in semiconductor, photonics, and high-end optical industries. Manufacturing Process Precision Investment CastingUtilizing the lost-wax casting method, we achieve dimensional tolerances within ±0.1mm for complex geometries. The process begins with 3D-printed wax patterns dipped in ceramic slurry, followed by high-temperature burnout and molten stainless steel pouring (typically 316L or 17-4PH grades). Surface TreatmentPost-casting treatments include: Electrolytic polishing for macro-level smoothing Diamond abrasive polishing (from 400# to 3000# grit progression) Final mirror polishing with 0.5μm diamond pasteSurface roughness achieves Ra ≤ 0.025μm (10μin) meeting ISO 12167-1 standards.
