Peb feem ntau hais tias stainless hlau qhov chaw yuav tsum tau polished. Vim li cas stainless hlau yuav tsum polished? Stainless hlau polishing technologies suav nrog txhua yam polishing, tshuaj polishing, electrolytic polishing, ultrasonic polishing, kua polishing thiab sib nqus abrasive polishing.
1. Mechanical polishing
Mechanical polishing yog ib txoj kev polishing kom tau ib tug du nto los ntawm kev txiav thiab tshem tawm cov convex qhov chaw tom qab polishing vim yas deformation ntawm cov khoom nto. Feem ntau, oilstone strips, wool log, sandpaper, thiab lwm yam. Kev tuav haujlwm yog txoj hauv kev tseem ceeb. Rau qhov tshwj xeeb xws li qhov chaw teb, turntables thiab lwm yam cuab yeej pab siv tau. Rau cov neeg uas xav tau qhov zoo ntawm qhov chaw, ultra precision polishing tuaj yeem siv. Super precision polishing yog siv cov cuab yeej tshwj xeeb abrasive, uas yog nias rau ntawm qhov chaw ntawm lub workpiece hauv cov kua polishing uas muaj cov abrasives tig ntawm qhov kub ceev. Qhov saum npoo roughness ntawm Ra0.008um tuaj yeem ua tiav los ntawm kev siv cov thev naus laus zis no, uas yog qhov siab tshaj plaws ntawm ntau txoj kev polishing. Txoj kev no feem ntau yog siv rau optical lens pwm.
2. Tshuaj polishing
Tshuaj polishing yog ua kom cov ntaub ntawv dissolve nyiam nyob rau hauv lub concave ib feem ntawm qhov chaw micro convex ib feem nyob rau hauv cov tshuaj nruab nrab, thiaj li yuav tau ib tug du nto. Lub ntsiab kom zoo dua ntawm txoj kev no yog tias nws tsis xav tau cov cuab yeej nyuaj, thiab tuaj yeem polish workpieces nrog cov duab nyuaj. Nws tuaj yeem polish ntau workpieces tib lub sijhawm, nrog kev ua haujlwm siab. Cov teeb meem tseem ceeb ntawm cov tshuaj polishing yog kev npaj cov tshuaj polishing. Qhov saum npoo roughness tau los ntawm tshuaj polishing feem ntau yog 10 um.
3. Electrolytic polishing
Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li cov tshuaj polishing, uas yog, los ntawm kev xaiv dissolving me me protruding qhov chaw ntawm cov khoom nto, qhov nto yog du. Piv nrog tshuaj polishing, nws tuaj yeem tshem tawm cov tshuaj tiv thaiv cathodic thiab muaj txiaj ntsig zoo dua. Cov txheej txheem electrochemical polishing tau muab faib ua ob theem:
(1) The macro leveling solution product diffuses into the electrolyte, and the geometric roughness of the material surface decreases, with Ra>1 awm.
(2) Tsawg lub teeb, anodized, nto brightness txhim kho, Ra<1um.
4. Ultrasonic polishing
Lub workpiece yog muab tso rau hauv lub abrasive ncua kev kawm ntawv thiab muab tso ua ke nyob rau hauv lub ultrasonic teb, thiab lub abrasive yog av thiab polished rau saum npoo ntawm lub workpiece los ntawm kev co ntawm lub ultrasonic. Ultrasonic machining muaj me me macro quab yuam thiab yuav tsis ua rau deformation ntawm lub workpiece, tab sis nws yog ib qho nyuaj rau ua thiab nruab tooling. Ultrasonic machining tuaj yeem ua ke nrog cov tshuaj los yog electrochemical txoj kev. Nyob rau hauv lub hauv paus ntawm kev daws corrosion thiab electrolysis, ultrasonic kev co yog siv los do cov tshuaj cais cov khoom yaj nyob rau saum npoo ntawm lub workpiece, thiab corrosion los yog electrolyte nyob ze ntawm qhov chaw yog uniform; Cov nyhuv cavitation ntawm ultrasonic yoj hauv cov kua kuj tuaj yeem cuam tshuam cov txheej txheem corrosion, uas yog qhov zoo rau qhov ci ntsa iab.
5. Dej polishing
Kua polishing yog ua kom tiav lub hom phiaj ntawm polishing los ntawm ntxuav lub workpiece nto nrog high-ceev ntws kua thiab abrasive hais nqa los ntawm nws. Cov txheej txheem muaj xws li abrasive dav hlau machining, kua dav hlau machining, hydrodynamic sib tsoo, thiab lwm yam. Hydrodynamic lapping yog tsav los ntawm hydraulic siab, uas ua rau cov kua nruab nrab nqa abrasive hais ntws rov qab thiab tawm thoob plaws lub workpiece nto ntawm kev kub ceev. Qhov nruab nrab yog tsuas yog ua los ntawm cov sib txuas tshwj xeeb (polymer zoo li cov khoom) nrog zoo flowability nyob rau hauv qis siab thiab tov nrog abrasives, uas yuav ua tau silicon carbide hmoov.
6. Sib nqus abrasive polishing
Sib nqus abrasive polishing yog siv cov hlau nplaum abrasive los tsim cov txhuam txhuam hauv qab qhov kev txiav txim ntawm cov hlau nplaum kom zom cov khoom ua haujlwm. Txoj kev no muaj kev ua haujlwm siab, ua haujlwm zoo, tswj tau yooj yim ntawm kev ua haujlwm thiab kev ua haujlwm zoo. Nrog rau abrasive kom zoo, qhov roughness ntawm qhov chaw tuaj yeem ncav cuag Ra0.1um.
Lub polishing nyob rau hauv yas pwm ua yog txawv heev los ntawm polishing nto yuav tsum tau nyob rau hauv lwm yam lag luam. Hais lus nruj me ntsis, pwm polishing yuav tsum hu ua daim iav ua. Nws tsis tsuas yog muaj kev xav tau siab rau polishing nws tus kheej, tab sis kuj muaj cov qauv siab rau qhov chaw flatness, smoothness thiab geometric raug. Feem ntau, nto polishing tsuas yog yuav tsum tau txais qhov ci ntsa iab. Tus qauv ntawm daim iav ua tau muab faib ua plaub theem: AO{{0}}Ra0.008L m, A1=Ra0.016um , A3=Ra0.032um, A4=Ra0.063um. Txij li nws yog ib qho nyuaj rau kev tswj cov geometric raug ntawm qhov chaw los ntawm electrolytic polishing, kua polishing thiab lwm txoj kev, thiab qhov zoo ntawm cov tshuaj polishing, ultrasonic polishing, sib nqus abrasive polishing thiab lwm txoj kev tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, daim iav ua ntawm precision pwm. feem ntau yog mechanical polishing.
