1. Kev Siv Lub Tshuab Ntsuas: Cov tshuaj polishing yog ua kom lub microscopic convex ib feem ntawm cov khoom siv hauv cov tshuaj nruab nrab kom zoo tshaj li qhov ua kom tiav, kom thiaj li tau txais qhov chaw du. Qhov tseem ceeb ntawm cov qauv no yog tias nws tsis tas yuav muaj cov khoom siv sib txawv, tuaj yeem txhuam cov khoom ua haujlwm nrog cov duab tsis sib xyaw, thiab tuaj yeem polish ntau qhov chaw ua haujlwm tib lub sijhawm, nrog kev ua haujlwm siab. Cov teeb meem tseem ceeb ntawm cov tshuaj polishing yog kev npaj ntawm cov tshuaj polishing. Qhov saum npoo roughness tau los ntawm tshuaj polishing yog feem ntau ntau 10 μm.
2. Kev ua haujlwm polishing: Cov hlau ions sib cais los ntawm qhov haujlwm tawm thiab phosphoric acid nyob rau hauv kev daws teeb meem ua cov ntawv xov phosphate kom tau adsorbed nyob rau saum npoo ntawm workpiece. Kev ua haujlwm siab thiab ceev ceev, nrog kev ntws ntawm lub qog ua kua xoos, qhov tsis sib xws tsis tu ncua hloov, thiab qhov ntxhib saum npoo yog maj mam plooj.
3. Mechanical polishing: Mechanical polishing tau muab faib ua kev ntxhib los mos thiab ua polishing. Kev ntxhib los mos polishing yog nqa nrog ntxhib ntxoo ntawm lub tshuab hluav taws xob polishing nrog kev sib hloov ceev ntawm 200-300 rpm. Hauv cov txheej txheem ntawm ntxhib polishing, nchuav coarser chromium oxide, aluminium oxide lossis magnesium oxide polishing kua, thiab khaws daim ntaub woolen rau ntawm polishing disc noo. Thaum lub sijhawm txheej txheem polishing, tuav tus qauv nruj nreem, rov qab rau hauv cov kev taw qhia radial ntawm polishing disc, thiab kho qhov kev thov siab tusyees. Nco ntsoov tias lub siab yuav tsum tsis txhob loj heev.
