Dab tsi yog txoj kev polishing txoj yas pwm?
(1) Tsav kom tau ciav hlau
Kev txiav txim siab, kev siv cov khoom siv ua kom cov khoom siv hlau ntim tom qab tshem tawm los ntawm kev siv txoj hlua hluavtaws los ntawm cov nplaim hluavtaws, feem ntau siv cov khoom siv roj zeb, lub log, cov ntawv xov xwm, thiab lwm yam. Cheebtsam ntawm cov khoom ntawm lub kiv puag ncig, muaj peev xwm siv cov cuab yeej xws li tigtable, siab nto zoo yuav siv tshaj lapping method.Super precision polishing yog sib tsoo tshwj xeeb cuab tam siv nyob rau hauv kev sib tsoo kua uas muaj abrasive
Tig zog.Qhov chaw npau npau ntawm Ra0.008 tuaj yeem ua tiav los ntawm kev siv cov tshuab no, uas yog qhov siab tshaj plaws ntawm txhua txoj kev siv txoj kev cai.Txoj no feem ntau siv cov lens moulds.
(2) tshuaj polishing
Kev siv tshuaj polishing yog ib qho ntawm cov khoom siv uas ua rau cov khoom siv ntawm ib qho chaw tshwm ntsej muag nyob hauv ib qho chaw hauv tshuaj lom neeg
Qhov zoo tshaj plaws tov yog kom tau ib qhov chaw saum npoo.Qhov zoo dua ntawm txoj kev no yog tias nws tsis siv cov khoom nyuab. Nws tuaj yeem txhuam cov haujlwm ua haujlwm nrog cov duab zoo, thiab nws tuaj yeem ua ntau yam workpieces nyob rau tib lub sij hawm nrog kev ua haujlwm zoo. Qhov teeb meem tseem ceeb ntawm cov tshuaj txhuam hniav yog npaj ua kom cov dej txias. Qhov paug ntawm qhov tshuaj txhuam los ntawm cov tshuaj polishing yog feem ntau ntawm cov microns.
(3) electrolytic polishing
Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li cov tshuaj siv tshuaj polishing, uas yog, lub nplaum yog du los ntawm selectively dissolving qhov me me protruding ntawm cov khoom ntws.Compared nrog tshuaj polishing, cov nyhuv ntawm cov tshuaj tiv thaiv cathode tau tshem tawm.Qhov txheej txheem electrochemical txheej txheem yog muab faib ua ob theem.
Cov tshuaj qhuav dej ua rau lub cev ua rau lub cev tsis sib haum xeeb, thiab qhov roughness degradation, Txo> lum.
Cov kua qaub qaum hlau me me kom zoo ib tus kabmob sab nrauv, npo ntawm qhov chaw nce, Rampage.
(4) ultrasonic polishing
Lub workpiece yog muab tso rau hauv kev ncua kev rho tawm thiab muab tso ua ke nyob rau hauv lub teb ultrasonic. Lub workpiece yuav ua tau rau hauv av thiab polished ntawm lub workpiece ntog nrog kev pab los ntawm ultrasonic oscillation.Ultrasonic machining macroscopic quab yuam yog me me, yuav tsis ua rau lub workpiece deformation, tab sis tus tooling ntau lawm thiab installation tsis yooj yim.Ultrasonic ua yuav tau chav nrog tshuaj los yog electrochemical txujci.Rau lub hauv paus ntawm kua corrosion thiab electrolysis, ultrasonic vibration stirring kua yog thov kom cais cov dissolved cov khoom ntawm lub workpiece nto, thiab cov corrosion los yog electrolyte nyob ze ntawm lub nplhaib.Ultrasonic cavitation hauv cov kua tau tseem inhibit tus txheej txheem corrosion.
(5) dej txhuam hniav
Cov dej phwj tuaj yeem siv rau kev khiav dej kub ceev thiab cov khoom uas nws ua rau nws ua rau nws ntuav ntawm cov khoom ua haujlwm kom mus cuag lub hom phiaj ntawm kev sib txuas lus.Txhob siv txoj kev ua yog kev txhaj tshuaj, kua tshuaj, kev sib tsoo hydrodynamic thiab lwm yam.Hydrodynamic sib tsoo tawm los ntawm hydraulic quab yuam, xwv kom cov kua nruab nrab ntawm cov khoom ua kua txav rov qab los ntawm kev ua hauj lwm ntws los ntawm kev kub ceev.Qhov nruab nrab yog ua los ntawm kev sib txuas lus tshwj xeeb (polymer zoo li yam) nrog kev yoojyim hauv siab tsawg thiab yog sib xyaw nrog abrasive, yuav tsum ua ntawm silicon carbide hmoov.
