Yuav ua li cas txhuam?
1. Mechanism polishing Mechanical polishing yog txheej txheem polishing uas tshem cov txheej txheem polished convex los ntawm yas deformation ntawm qhov chaw ntawm cov khoom kom tau txais qhov chaw du. Feem ntau, cov roj pob zeb ntoo, wool log, ntawv pleev xim, thiab lwm yam yog siv, feem ntau los ntawm kev ua haujlwm ntawm tes, thiab cov khoom siv tshwj xeeb xws li kev sib hloov rau lub cev, muaj cov khoom siv pabcuam xws li lub taub hau tuaj yeem siv, thiab cov txheej txheem ntawm super -dawb polishing tuaj yeem siv rau qhov tsis zoo. Ultra-nplua sib tsoo thiab polishing yog cov khoom siv sib tsoo tshwj xeeb. Hauv cov kua polishing uas muaj cov abrasive, nws tau nias tiv thaiv qhov machined nto tau ua lub suab nrawm tig tau. Nrog cov thev naus laus zis, qhov saum npoo ntawm Ra0.008 μm tuaj yeem ua tiav, uas yog qhov siab tshaj plaws ntawm ntau cov txheej txheem polishing. Cov qauv no feem ntau siv rau hauv kev kho qhov muag lens pwm.
2. Kev Ntsuas Tshuaj polishing yog polishing yog txheej txheem hauv cov khoom siv yog fused me ntsis hauv qhov nruab nrab ntawm cov tshuaj nruab nrab, thiab cov lus sib dhos yog qhov tshwj xeeb kom tau txais qhov chaw du. Qhov tseem ceeb tseem ceeb ntawm cov qauv no yog tias nws tuaj yeem txhuam cov haujlwm uas muaj cov duab sib txawv uas tsis muaj cov cuab yeej ua tau yooj yim, 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 tsim cov kua tshuaj polishing. Qhov saum npoo roughness tau los ntawm tshuaj polishing yog feem ntau ntau 10 μm.
3. Kev Siv Hluav Taws Xob Lub hauv paus ntsiab lus ntawm kev ntsuas hluav taws xob zoo ib yam li tshuaj lom neeg polishing, uas yog xaiv kom yaj lub ntsej muag ntawm cov khoom kom ua rau saum npoo du. Piv nrog tshuaj polishing, cov nyhuv ntawm cathode cov tshuaj tiv thaiv tuaj yeem raug tshem tawm, thiab cov nyhuv yog qhov zoo. Cov txheej txheem electrochemical polishing tau muab faib ua ob theem: (1) Macro-leveling Cov khoom tawg ua lub ntsej muag tsis sib haum, thiab qhov saum npoo ntawm cov khoom poob, Ra> 1 .m. (2) Qes qis-theem kev ua haujlwm Anodic polarization, lub teeb ci ntsa iab zoo dua, Ra <>
4. Ultrasonic polishing Lub workpiece muab tso rau qhov kev ua kom tsis muaj qhov cuam tshuam thiab muab tso ua ke hauv ultrasonic qhov chaw. Cov abrasive yog av thiab polished nyob rau saum npoo ntawm workpiece los ntawm kev co ntawm ultrasonic nthwv dej. Ultrasonic machining muaj qhov me me macroscopic quab yuam thiab tsis ua rau lub cev tsis ua haujlwm, tab sis nws nyuaj rau kev tsim khoom thiab txhim kho lub cuab tam. Kev ua ultrasonic tuaj yeem ua ke nrog cov txheej txheem tshuaj lossis tshuab hluav taws xob. Rau lub hauv paus ntawm cov tshuaj tiv thaiv xeb thiab xaim hluav taws xob, qhov kev co ultrasonic vibration stirring tov yog thov kom cais cov khoom tawg nyob saum npoo ntawm qhov chaw ua haujlwm, thiab qhov chaw xeb lossis xaim hluav taws xob nyob ze rau saum npoo yog yam tsis zoo; qhov cavitation ntawm ultrasonic nthwv dej hauv cov kua kuj tseem tuaj yeem tiv thaiv qhov txheej txheem xeb, uas yog qhov zoo rau cov nplaim taws ua kom pom kev.
5. Lub cev txhaws npliag npliag muaj kev ua tiav los ntawm polishing qhov saum npoo ntawm cov haujlwm ua haujlwm nrog cov nplawm ntws ntawm cov kua thiab cov nplawm abrasive uas nws nqa. Cov kev siv dav dav yog: abrasive dav hlau ua, kua hlau ua, kev sib tsoo hydrodynamic, thiab cov zoo li. Kev sib tsoo hydrodynamic yog hydraulically tsav ua rau cov kua nruab nrab ua kom muaj cov nplawm ntuag ua rau ntws rov qab thiab dhau ntawm qhov chaw ntawm lub workpiece ntawm kev kub ceev. Qhov nruab nrab yog tsuas yog ua los ntawm cov sib txuas tshwj xeeb uas ntws tawm ntawm lub zog qis dua thiab yog doped nrog kev ua kom tsis zoo, thiab cov xaum yuav tuaj yeem ua los ntawm silicon carbide hmoov.
6. Sib Nqus Abrasive Polishing Sib Nqus Abrasive polishing yog kev siv cov khoom siv sib nqus los ua cov txhuam abrasive nyob hauv kev ua ntawm lub sib nqus ua kom sib tsoo lub ntsej muag. Hom no muaj kev ua haujlwm siab, kev ua haujlwm zoo, tswj tau yooj yim ntawm kev ua haujlwm thiab kev ua haujlwm zoo. Nrog kev ua kom haum abrasive, qhov saum npoo roughness tuaj yeem ncav cuag Ra 0.1 μm.
