1. Mechanical polishing Mechanical polishing yog txheej txheem polishing uas tau txais cov nplaim du los ntawm kev tshem cov txheej txheem polished los ntawm kev txiav thiab yas deformation ntawm qhov chaw ntawm cov khoom. Feem ntau, koj siv whetstone ib daim hlab, wool log, sandpaper, thiab lwm yam, feem ntau yog kev tuav haujlwm, thiab cov khoom siv tshwj xeeb xws li tig Los rau sab cev, cov khoom siv pabcuam xws li turntables tuaj yeem siv. Rau siab nto zoo yuav tsum, ultra-leej polishing yuav siv tau. Kev sib xyaw ultra-leej polishing polishing adopts kev sib tsoo tshwj xeeb. Hauv kev sib tsoo polishing kua uas muaj abrasives, nws yog nias tiv thaiv sab saum npoo ntawm lub workpiece kom tiav rau kev kub ceev. Siv cov thev naus laus zis no tuaj yeem ua tiav saum npoo ntawm Ra0.008μm, 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 Cov Tshuaj polishing yog ua kom cov nplaim ntawm cov khoom siv me me ntawm cov tshuaj lom hauv lub nruab nrab kom thim raws li qhov xav tau, 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. Lub hauv paus teeb meem ntawm cov tshuaj polishing yog kev npaj cov kua polishing. Qhov saum npoo roughness tau los ntawm tshuaj polishing yog feem ntau ntau 10 μm.
3. Electrolytic polishing Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li tshuaj polishing, uas yog, los ntawm kev xaiv lub zom me me uas tawm ntawm qhov chaw ntawm cov khoom siv, saum npoo yog du. Piv nrog tshuaj polishing, cov nyhuv ntawm cathode cov tshuaj tiv thaiv tuaj yeem raug tshem tawm, thiab cov nyhuv zoo dua. Cov txheej txheem hluav taws xob electrochemical tau muab faib ua ob theem: (1) Macro qib theem Cov khoom tawg ua rau hluav taws xob, thiab qhov saum npoo ntawm cov khoom poob qis, Ra> 1 μm. (2) Qes qis kev nyab xeeb qib Anode polarization, lub teeb ci ntsa iab zoo dua, Ra <>
4. Ultrasonic polishing Muab cov haujlwm rau hauv qhov ua kom tawg thiab muab tso rau hauv daim teb ultrasonic ua ke, cia siab rau kev co ntawm ultrasonic nthwv dej kom ua qhov abrasive sib tsoo thiab polishing nyob rau saum npoo ntawm lub workpiece. Ultrasonic machining muaj zog me me tsis muaj zog thiab tsis ua rau workpiece deformation, tab sis tooling ntau lawm thiab kev teeb tsa yog qhov nyuaj. Kev ua ultrasonic tuaj yeem ua ke nrog cov txheej txheem tshuaj lossis tshuab hluav taws xob. Ntawm lub hauv paus ntawm kev daws qhov kho xeb thiab xaim hluav taws xob, ultrasonic kev co yog siv los txhawm rau cov tshuaj kom yaj cov khoom yaj nyob rau sab saum toj ntawm qhov chaw ua haujlwm, thiab qhov kev xeb lossis electrolyte nyob ze rau saum npoo yog sib npaug; qhov cavitation ntawm ultrasonic tsis nyob hauv cov kua kuj tseem tuaj yeem tiv thaiv cov txheej txheem corrosion thiab pab txhawb lub ntsej muag.
5. Lub ntsej muag npliag dej Lub cev polishing siv los ntxuav cov nplaim haujlwm ntawm cov haujlwm ua haujlwm raws li cov kua hluav taws xob uas muaj lub siab khiav ceev thiab cov nplawm tshem tawm los ntawm nws kom ua tiav lub hom phiaj ntawm polishing. Cov txheej txheem sib txawv yog: cov roj dav hlau ua tiav, cov dej dav hlau ua, kev sib tsoo hydrodynamic, thiab lwm yam. Hydrodynamic sib tsoo yog tsav los ntawm hydraulic siab, kom cov kua nruab nrab nqa cov abrasive hais ntws rov qab thiab thoob plaws qhov chaw ua haujlwm saum npoo ntawm kev kub ceev. Qhov nruab nrab yog tsuas yog ua los ntawm cov sib txuas tshwj xeeb uas ntws los ntawm hauv qis lub zog thiab xyaw nrog abrasives. Cov abrasives tuaj yeem yog cov tshuaj silicon carbide hmoov.
