Lub ntsiab lus thiab kev siv ntawm polishing
Vim li cas peb thiaj yuav tsum ua cov khoom sib txawv ntawm cov khoom siv?
Cov txheej txheem kev kho deg yuav txawv rau cov hom phiaj sib txawv.
1 Peb lub hom phiaj ntawm kev ua cov khoom ntawm cov tshuab:
1.1 Kev Ua Taug Kev Sib Nraim rau kev tau txais qhov tseeb
Rau qhov sib txuam nrog cov kev sib txuam, cov cai tau ua kom raug (suav nrog qhov raug) qhov tseeb) feem ntau yog qhov tseeb thiab yog thiab qhov tseeb ntawm sab nraud muaj feem xyuam. Txhawm rau kom tau qhov raug, cov sib tov kev ntxhib yuav tsum ua tiav. Piv txwv li: qhov tseeb nws tau6 feem ntau yuav tsum muaj kev sib raug zoo RA0.8.
[Cov cuab yeej siv tau txhais tau tias]:
- Tig los yog milling
- Nplua zoo heev
- Kev sib tsoo zoo
- Kev sib tsoo
1.2 Cov txheej txheem sib tw deg rau tau txais cov khoom sib txawv
1.2.1 Tau txais kev hnav tsis kam
[Txoj Kev Sib Koom Tes]
- Sib tsoo tom qab tawv lossis carburizing / quenching (nitriving)
- Sib tsoo thiab polishing tom qab nyuaj chrome plating
1.2.2 Tau txais lub xeev kev ntxhov siab zoo
[Txoj Kev Sib Koom Tes]
- Kev sib tsoo thiab sib tsoo
- Nto Cua Sov Kho thiab Kev Sib Tsoo
- Deg rolling los yog txhaj txwv chaeening ua raws li los ntawm kev sib tsoo zoo
1.3 Kev Ua Txoj Kev Yuav kom tau txais cov khoom sib npaug saum toj
[Txoj Kev Sib Koom Tes]
- Electroplating thiab polishing
2 Hlau Hlau Polishing Tshuab
2.1 Qhov tseem ceeb nws yog qhov tseem ceeb ntawm thaj teb ntawm cov thev naus laus zis thiab engineering, tshwj xeeb yog nyob rau hauv kev lag luam tsim khoom, txheej, anodizing thiab ntau txheej txheej kho cov txheej txheem.
2.2 Vim li cas thawj zaug uas yog thawj qhov chaw nyob thiab ua tiav cov txiaj ntsig ntawm qhov chaw ua haujlwm yog li tseem ceeb?Vim tias lawv yog cov ntsiab lus pib thiab hom phiaj ntawm cov haujlwm polishing, nrog rau cov hom sib tsoo, cov khoom uas yuav tsum tau ua rau lub tshuab Polishing.
2.3 Sib tsoo & theem polishing thiab trajectories
Plaub yam theem ntawmkev sib tsoothiabPOLISHING]: Raws li qhov pib thiab kawg rougness ra muaj nuj nqis ntawm lub workpiece, ntxhoo sib tsoo - zoo sib tsoo - sib tsoo zoo - sib tsoo - polishing. Cov abrasives ntau ntawm coarse kom zoo. Cov cuab yeej sib tsoo thiab cov workpiece yuav tsum raug muab ntxuav txhua lub sijhawm lawv raug hloov.
2.3.1 Cov cuab yeej sib tsoo yog qhov nyuaj, cov nyhuv microus txiav thiab cov nyhuv loj dua, thiab qhov loj me thiab roughness muaj qhov hloov pauv pom tseeb.
2.3.2 Kev siv tshuab polishing yog cov khoom siv txiav ntau dua li sib tsoo. Cov cuab yeej polishing yog ua los ntawm cov khoom muag muag, uas tuaj yeem txo cov roughness tab sis tsis tuaj yeem hloov qhov tseeb ntawm qhov loj me thiab cov duab. Qhov roughness tuaj yeem ncav cuag tsawg dua 0.4μm.
2.4 Peb lub ntsiab lus ntawm cov npoo ua tiav kev kho mob: sib tsoo, polishing, thiab xov
2.4.1 lub tswv yim ntawm cov neeg kho tshuab sib tsoo thiab polishing
Txawm hais tias ob qho tib si tshuab sib tsoo thiab cov neeg kho tshuab polishing tuaj yeem txo cov npoo av, tseem muaj sib txawv:
- 【Neeg kho tshuab Polishing】: Nws suav nrog kev nkag siab ntev, tsim kev ua siab ntev thiab ua hauj lwm thev taus. Nws yuav tsum ua kom ntseeg tau qhov ntev ntev, ua rau muaj kev pheej hmoo thiab muaj kev zam lub sijhawm hauv av thaum txo cov kev sib tw.
- Txhua yam polishing: nws txawv ntawm polishing. Nws tsuas yog txhim kho cov npoo tiav, tab sis tsis muaj peev xwm ua tsis tau kev lees paub. Nws lub ci ci yog siab dua thiab ci dua li polishing. Cov txheej txheem sib xws ntawm cov neeg kho tshuab polishing yog sib tsoo.
2.4.2 [Ua tiav] yog kev sib tsoo thiab cov txheej txheem tseem ceeb ntawm kev sib tsoo thiab tsuas yog tshem tawm cov ntsej muag zoo nkauj thiab muaj zog ntxiv ntxiv rau nws cov npoo.
Qhov tseeb thiab roughness ntawm ib feem saum npoo muaj ib qho kev cuam tshuam zoo rau nws lub neej thiab kev ua tau zoo. Cov txheej txheem deteriorated sab laug los ntawm Edm thiab Micro Cov nrib pleb sab laug los ntawm kev sib tsoo yuav cuam tshuam rau lub neej kev pabcuam ntawm cov ntu.
① Cov txheej txheem ua tiav tau muab cov khoom siv me me dawb thiab yog siv los txhim kho kom zoo. Ib qho nyiaj me me yog siv los txhim kho cov tshuab raug (xws li cov qauv raug thiab cov qauv raug), tab sis nws tsis tuaj yeem siv los txhim kho txoj haujlwm raug.
Ua tiav tiav yog cov txheej txheem ntawm micro-txiav thiab extruding lub workpiece nto nrog cov abrasives zoo. Cov saum npoo yog cov txheej txheemyees, lub zog txiav thiab txiav cov cua sov yog qhov me me heev, thiab ua tau zoo heev tuaj yeem tau txais. Ua tiav tiav yog cov txheej txheem micro-ua thiab tsis tuaj yeem kho qhov chaw loj dua. Kev ua tau zoo yuav tsum tau ua ua ntej ua.
Lub ntsiab lus ntawm cov hlau saum npoo npoo yog saum npoo sau cov khoom siv micro-tshem tawm.
3. Tam sim no cov txheej txheem Polishing, 3.2 Kev Siv Tshuaj Polishing, 3.4 polishingic polishing, 3.5 kua roj polishing,
3.1 Txhua Yam Polishing
Neeg kho tshuab polishing yog txoj cai polishing yog txoj kev sib ntseeg ntawm kev txiav thiab cov khoom sib dhos ntawm cov khoom sib dhos kom tshem tawm cov polished protrusions kom tau txais qhov chaw du.
Siv cov thev naus laus zis no, kev siv tshuab polishing tuaj yeem ua tiav qhov chaw ntawm Ra0.008μm, uas yog qhov siab tshaj ntawm ntau txoj kev polishing. Hom no feem ntau siv nyob rau hauv lub lens kho qhov muag tuaj pwm.
3.2 Tshuaj lom neeg polishing
Tshuaj lom neeg polishing yog ua kom lub tshuab hluav taws xob convex seem ntawm cov khoom sib txawv ntawm cov tshuaj nruab nrab ntawm cov nruab nrab concave, yog li kom tau txais qhov chaw du. Lub ntsiab zoo ntawm hom no yog tias nws tsis xav tau cov khoom siv nyuaj, tuaj yeem ua haujlwm Polish nrog cov duab ua ke, tuaj yeem ua haujlwm ntau lub sijhawm, thiab yog qhov ua tau zoo heev. Qhov teeb meem tseem ceeb ntawm kev siv tshuaj polishing yog qhov kev npaj ntawm cov kua polishing. Qhov saum npoo roughness tau los ntawm kev tshuaj lom neeg yog feem ntau ntau kaum ntawm μm.
3.3 electrolytic polishing
Electrolytic POLISHING, tseem hu ua electrochemical polishing, xaiv tau dission procolves tiny prodions rau saum npoo ntawm cov khoom kom du.
Piv nrog tshuaj polishing, cov nyhuv ntawm canhode cov tshuaj tiv thaiv tuaj yeem tshem tawm thiab cov nyhuv zoo dua. Cov txheej txheem hluav taws xob hauv tshuab hluav taws xob polishing tau muab faib ua ob kauj ruam:
(1) macro-leveling: Cov khoom uas dissolves diffuse rau hauv electrolyte, thiab geometric roughness ntawm cov khoom saum npoo av poob qis, ra 1μm.
(2) gloss smoothing: anodic polarization: nto ci yog txhim kho, ralμm.
3.4 POLISHING
Lub workpiece tau muab tso rau hauv qhov kev txwv tsis meej pem thiab muab tso rau hauv ib daim teb ultrasonic. Cov abrasive yog av thiab polished ntawm workpiece nto los ntawm oscillation ntawm ultrasonic yoj. Ultrasonic machining muaj me me macroscopic thiab yuav tsis ua rau deformation ntawm lub workpiece, tab sis kev pleev khoom yog qhov nyuaj rau kev tsim khoom thiab nruab.
Ultrasonic machining tuaj yeem ua ke nrog cov tshuaj lom neeg lossis hluav taws xob. Raws lub hauv paus ntawm kev daws teeb meem corrosion thiab electrolysis, ultrasonic co yog thov kom cais cov khoom uas tsis dhau ntawm qhov chaw ua haujlwm lossis hluav taws xob nyob ze ntawm cov khaub ncaws saum npoo; Cov nyhom cov nyhuv ntawm ultrasonic tsis nyob rau hauv cov kua kuj tseem tuaj yeem ua rau cov txheej txheem xeb thiab pab txhawb qhov saum npoo kom nruj.
3.5 kua roj polishing
Kua polishing relies ntawm high-ceev ntws kua thiab cov abrasive hais nws nqa kom txhuam qhov ua haujlwm kom ua tiav lub hom phiaj ntawm polishing.
Cov hau kev feem ntau suav nrog: Cov dav hlau tua phom, ua kua dav hlau ua, cov dej sib tsoo, cov kua dej sib tsoo, thiab lwm yam.
3.6 sib sib kev sib tsoo thiab sib xyaw ua ke
Sib tsoo sib tsoo thiab polishing siv abrasives los tsim cov kev txhuam cov txiv duaj nyob rau hauv qhov sib nqus kom zom cov workpiece.
Cov qauv no tau ua haujlwm siab, ua tau zoo, tswj tau yooj yim, thiab kev ua haujlwm zoo. Nrog cov abrasives tsim nyog, qhov saum npoo roughness tuaj yeem ncav cuag Ra0.1μm.
Los ntawm cov ntawv no, Kuv ntseeg tias koj yuav muaj kev nkag siab zoo ntawm polishing. Txawv sib txawv ntawm Polishing tshuab yuav txiav txim cov nyhuv, kev ua tau zoo, raug nqi thiab lwm yam ntsuas ntawm ua tiav cov hom phiaj txawv sib txawv.
Dab tsi ntawm polishing tshuab koj lub tuam txhab lossis koj cov neeg yuav tsum tau sib phim raws li tus neeg siv lub lag luam xav tau, kev txhim kho nyiaj txiag, kev lag luam thiab lwm yam kev lag luam.
Tau kawg, muaj ib txoj kev yooj yim thiab ua tau zoo los cuam tshuam nrog qhov no. Thov sab laj peb cov neeg ua haujlwm muag los pab koj.
