Polishing yog dab tsi?

Polishing yog cov txheej txheem ceev faj txhawm rau ua kom tiav qhov du thiab pom ntawm cov khoom. Nws yog feem ntau ua haujlwm thoob plaws kev lag luam rau ob qho tib si ua haujlwm thiab zoo nkauj. Cov txheej txheem no suav nrog kev siv cov nplua-micron lossis sub-micron abrasive hais ua ke nrog cov kua nruab nrab, ua rau nws "ntub" txheej txheem.
Lub hom phiaj tseem ceeb ntawm polishing yog tsim kom muaj qhov ua tiav tiav, feem ntau ua tiav siv cov ntaub qhwv tshwj xeeb uas tuav cov khoom abrasive. Cov ntaub qhwv no, feem ntau yog softer dua li lub workpiece, maj mam abrade nto, ua rau cov khoom siv tsawg tsawg, feem ntau ntsuas hauv microns. Ua ntej lub polishing theem, lub workpiece nto tiav yog feem ntau pre-kho los xyuas kom meej tias nws ua tau raws li cov qauv zoo, feem ntau muaj xws li ib tug "lapped" nto.
Polished nto ua haujlwm ntau yam. Lawv tso cai rau kev sib khi zoo tiv thaiv cov pa roj thiab cov kua dej, ua kom haum rau cov kev nyiam ntawm cov tshuaj pleev ib ce, thiab pab ntsuas qhov tseeb siv cov cuab yeej kho qhov muag. Ntxiv mus, polished nto txo ​​ob qho tib si saum npoo thiab sub-surface puas, muab uniformity rau cov txheej txheem zoo li epitaxy, thiab txhim khu kev txiav cov npoo rau precision.
Ntau hom kev polishing muaj nyob, suav nrog cov uas siv cov ntaub mos los yog tawv nrog cov pa lossis tshwj xeeb abrasive slurries, pob zeb diamond abrasive slurries (dej los yog roj-raws li), thiab pob zeb diamond compounds nrog lubricants. Tsis tas li ntawd, taag-abrasive films, lapping, thiab pob zeb diamond slurry polishing ntawm composite los yog hlau daim hlau pab txhawb rau ntau hom kev polishing muaj.
Thaum sib piv lapping rau polishing, qhov sib txawv tshwm sim. Lapping ua rau lub matte, uas tsis yog-reflective nto nrog ib tug multi-directional lay qauv, feem ntau ua hauj lwm lub hom phiaj xws li daim ntawv thov txheej. Ntawm qhov tod tes, polishing yields ib qho kev ua tiav, feem ntau ua raws li theem ob, catering rau sealing, cosmetic, thiab lub teeb-band soj ntsuam yuav tsum tau.
Cov txheej txheem ntawm polishing feem ntau koom nrog kev siv lub polishing ncoo thiab dej-raws li slurry kom ua tiav qhov xav tau los yog qhov pom tseeb. Ua kom ntseeg tau tias tsis muaj qhov tsis zoo thiab tsis muaj khawb yog qhov tseem ceeb, feem ntau yuav tsum tau siv cov caustic polishing slurries. Yog li ntawd, stainless hlau Cheebtsam yog nyiam vim lawv tsis kam mus rau cov tshuaj no. Tsis tas li ntawd, yaug lub workpiece thaum kawg ntawm lub voj voog txheej txheem, feem ntau nrog dej, xyuas kom tsis muaj qhov seem seem ntawm polishing xov xwm.
Hais txog cov cuab yeej siv, qhov sib txawv ntawm lapping thiab polishing tshuab yog hloov maj mam. Thaum ob leeg siv cov txheej txheem zoo sib xws, qhov nro ntawm polishing feem ntau yog siab dua vim yog siv cov slurries abrasive. Polished nto nthuav dav qhov nro ntau dua, cuam tshuam lub zog horsepower rau cov khoom siv tsav.
