Polishing yog ib qho tseem ceeb ntawm kev ua tiav cov txheej txheem ua haujlwm hauv kev lag luam hlau los txhim kho kev zoo nkauj, kev ua haujlwm, thiab ua haujlwm ntev ntawm cov hlau. Txawm hais tias nws yog rau cov khoom siv kho kom zoo nkauj, cov ntawv thov kev lag luam, lossis cov khoom siv precision, cov txheej txheem polishing zoo tuaj yeem hloov cov hlau ntxhib thiab tsis muaj zog rau hauv qhov ci, muaj kev cuam tshuam, thiab tsis muaj qhov tsis zoo. Kab lus no muab cov ntsiab lus dav dav ntawm cov txheej txheem hlau nto polishing, los ntawm nws cov hauv paus ntsiab lus mus rau cov txheej txheem siab heev.
1. Lub hauv paus ntawm Polishing:
Polishing yog txheej txheem ntawm tshem tawm imperfections, khawb, blemishes, thiab roughness ntawm ib tug hlau nto los ntawm puas. Nws koom nrog kev siv cov ntaub ntawv abrasive thiab ua kom zoo dua grits kom ua tiav qhov xav tau smoothness thiab ci. Lub hom phiaj tseem ceeb ntawm cov hlau nto polishing yog txhawm rau txhim kho qhov zoo ntawm qhov chaw, tshem tawm oxidation los yog corrosion, npaj qhov chaw rau plating los yog txheej, thiab tsim kom pom qhov zoo nkauj tiav.
2. Kev Npaj Nto:
Ua ntej pib txheej txheem polishing, kev npaj txhij txhua yog qhov tseem ceeb. Qhov no suav nrog kev ntxuav cov hlau saum npoo kom tshem tawm cov av, roj, cov kab mob, thiab cov txheej txheem yav dhau los. Ib qho chaw huv huv kom ntseeg tau tias cov khoom siv polishing tuaj yeem cuam tshuam nrog cov hlau, ua kom cov txiaj ntsig zoo dua.
3. Kev xaiv Polishing Cheebtsam:
Polishing compounds ua lub luag haujlwm tseem ceeb hauv kev ua tiav ntawm cov txheej txheem polishing. Cov tshuaj no muaj nyob rau hauv ntau hom, xws li pastes, kua, thiab hmoov. Lawv yog formulated nrog abrasive hais tshem tawm nyob rau hauv ib tug carrier nruab nrab. Kev xaiv ntawm qhov sib xyaw yog nyob ntawm hom hlau, qhov xav tau tiav, thiab qib ntawm kev puas tsuaj yuav tsum tau ua. Feem ntau siv abrasives suav nrog aluminium oxide, silicon carbide, thiab pob zeb diamond.
4. Cov txheej txheem polishing:
Muaj ntau ntau txoj hauv kev ua haujlwm hauv cov hlau polishing, txhua qhov kev pabcuam rau cov kev xav tau sib txawv thiab cov nyom:
a. Tes Polishing: Txoj kev niaj hnub no suav nrog kev siv cov khoom siv polishing siv cov ntaub, txhuam hniav, lossis cov ntaub qhwv. Nws yog haum rau cov khoom me me thiab intricate.
b. Tshuab Polishing: Automated polishing tshuab nruab nrog rotating log, siv tawv, los yog txhuam yog siv rau qhov chaw loj los yog ntau lawm. Cov tshuab no muab cov txiaj ntsig zoo ib yam thiab nce kev ua haujlwm zoo.
c. Electropolishing: Cov txheej txheem electrochemical no suav nrog kev tso cov khoom hlau hauv cov tshuaj electrolyte thiab siv hluav taws xob tam sim no. Nws tshem tawm ib txheej nyias ntawm cov khoom, uas ua rau txhim kho nto tiav thiab txo micro-roughness.
d. Vibratory Polishing: Cov khoom raug muab tso rau hauv lub tshuab vibratory nrog rau cov xov xwm abrasive thiab cov kua ua kua. Qhov kev txiav txim tumbling tsim kev sib txhuam, maj mam polishing cov hlau nto.
5. Cov kauj ruam polishing:
Cov txheej txheem polishing feem ntau suav nrog cov kauj ruam hauv qab no:
a. Coarse Sib Tsoo: Kev tshem tawm thawj zaug ntawm qhov tsis zoo loj dua siv cov khoom siv ntxhib.
b. Fine Grinding: Smoothing saum npoo siv finer abrasives los npaj rau theem polishing.
c. Polishing: Siv cov khoom sib txuas ua kom zoo dua polishing kom ua tiav qhov xav tau ua tiav.
d. Buffing: Siv cov ntaub ntawv mos zoo li daim ntaub los yog muaj cov khoom siv polishing los tsim kom muaj qhov kawg-gloss tiav.
6. Kev ntsuas kev nyab xeeb:
Kev nyab xeeb yog qhov tseem ceeb thaum ua haujlwm nrog polishing tebchaw thiab tshuab. Cov neeg ua haujlwm yuav tsum siv cov cuab yeej tiv thaiv xws li hnab looj tes, tsom iav, thiab lub ntsej muag ua pa tiv thaiv kom tsis txhob raug cov khoom phom sij thiab cov khoom siv.
7. Cov kev sib tw thiab kev txiav txim siab:
Cov hlau sib txawv ua rau muaj teeb meem tshwj xeeb thaum lub sij hawm polishing txheej txheem vim qhov txawv ntawm hardness, grain qauv, thiab tshuaj reactivity. Kev paub txaus ntawm cov khoom siv yog qhov tseem ceeb los xaiv cov txheej txheem polishing tsim nyog thiab cov khoom sib txuas.
8. Advanced Polishing Techniques:
Tsis ntev los no kev nce qib hauv thev naus laus zis tau coj mus rau cov txheej txheem polishing tshiab:
a. Laser Polishing: Siv cov teeb pom kev zoo laser los xaiv yaj thiab rov ua kom lub ntsej muag, ua rau kom tiav.
b. Sib Nqus Abrasive Polishing: Koom nrog siv cov khoom siv hlau nplaum sib nqus los txhuam qhov nyuaj thiab nyuaj rau ncav cuag.
9. Kev soj ntsuam zaum kawg thiab kev tswj xyuas zoo:
Tom qab polishing, kev tshuaj xyuas zoo yog tsim nyog los xyuas kom meej tias qhov kev xav tau tiav lawm. Kev tswj xyuas zoo suav nrog kev tshuaj xyuas qhov muag, ntsuas qhov roughness ntawm qhov chaw, thiab kev ntsuam xyuas ntawm gloss thiab reflectivity.
10. Xaus:
Hlau nto polishing yog ib qho nyuaj thiab tseem ceeb txheej txheem nyob rau hauv lub ntiaj teb no ntawm metalworking. Nws hloov cov hlau tsis zoo rau hauv qhov muag pom kev, ua haujlwm zoo, thiab cov khoom zoo. Nrog rau kev nkag siab tob txog cov hauv paus ntsiab lus, cov txheej txheem, thiab kev ntsuas kev nyab xeeb, cov kws tshaj lij tuaj yeem ua tiav cov txiaj ntsig zoo, ua rau muaj kev zoo nkauj thiab ntev ntawm cov khoom hlau hauv ntau yam lag luam.
