Hauvprecision polishingntawm cov hlau, optics, thiab cov ceramics siab heev, lub hom phiaj yog kom ua tiav qhov chaw tsis muaj qhov tsis zoo nrog qhov kev puas tsuaj me me thiab ua tiav zoo ib yam. Silicon carbide (SiC) yog dav siv los ua abrasive vim nws hardness thiab controllable puas. Thaum sib pivSiC ntawm 88% purity piv rau 90% purityntawm qhovtib grit loj, qhov zoo li me me 2% purity sib txawv yuav txiav txim siab:90% purity tsis tu ncua outperforms 88% purityhauv kev siv precision.
NtawmZhenAn, nrog30 xyoo ntawm kev paubKev muab SiC abrasives rau kev ua tiav qhov tseeb, peb piav qhia tias vim li cas cov purity siab dua muab cov txiaj ntsig zoo dua thiab nws txhais li cas rau hauv qhov chaw polished zoo dua.
1. Precision Polishing: Dab tsi txhais tau tias "zoo dua"?
Precision polishing xav tau:
Uniform kos qauv - zoo, cov cim zoo ib yam uas tshem tau tag nrho hauv cov kauj ruam tom ntej.
Tsawg kawg embedded hais - Cov kab mob uas ua rau hawb pob, tawg, lossis xeb.
Ntxuav saum npoo - tsis muaj tshuaj lom neeg uas cuam tshuam rau txheej adhesion lossis optical clarity.
Rov ua dua qhov tshwm sim - zoo tib yam nto tag hla cov khoom siv thiab cov neeg ua haujlwm.
Kev ua tiav qhov no nyob ntawm tsis yog tsuas yog ntawm grit loj tab sis kuj nyob ntawmabrasive purity, vim impurities dictate yuav ua li cas huv si thiab kwv yees cov abrasive txiav thiab puas.
2. Tib Grit - Vim li cas Purity Matters
Grit lojkho qhov nominal txiav qhov tob rau ib feem cuam tshuam.
Puritytxiav txim qhovtshuaj muaj pes tsawg leeg ntawm abrasive mix:
88% SIB→ ~ 12% impurities (silica, dawb carbon, hlau oxides).
90% SiC→ ~ 10% impurities → ntau dua SiC ib chav tsev loj.
Nrog grit tsau,impurities dhau los ua qhov sib txawv tseem ceebcuam tshuam rau polishing zoo.
3. Yuav ua li cas Impurities Degrade Precision Polishing
Irregular Fracture & Deep Scratches
Cov impurities tsim cov ntsiab lus tsis muaj zog hauv SiC nplej, ua rau puas tsuaj. Qee cov khoom tawg mus rau hauv cov ntse ntse, cov khoom loj loj uas tsim cov khoom sib sib zog nqus sib sib zog nqus resistant rau tom qab polishing theem.
Embedded hauv Workpiece
Softer impurity hais (xws li, silica, carbon) tuaj yeem embed nyob rau hauv softer hlau los yog ilv qhov chaw, tawm mus tas li blemishes uas tawg lub teeb (optics) los yog pib corrosion (hlau).
Residue Formation
Reactive impurities tuaj yeem tawm hauv cov yeeb yaj kiab tshuaj (xws li, silica gel, carbonaceous residue) uas cuam tshuam nrog cov txheej txheem polishing los yog txheej txheej tom ntej, txo qhov huv ntawm qhov chaw.
Hnav tsis sib haum
Mixed-hardness particles hnav ntawm tus nqi sib txawv, ua rau tsis sib xws txiav txiav thiab poob ntawm kev tswj hwm saum npoo av.
4. Vim li cas 90% Purity zoo dua rau Precision Polishing
Uniform Cutting Edges
Cov ntsiab lus SiC siab dua txhais tau hais tias tsawg dua impurity-induced flaws, yog li cov nplej puas sib npaug, nthuav tawm cov npoo ntse uas tsim tau zoo, sib npaug sib npaug.
Tsawg Embedded Particles
Cov khoom siv ntxhua khaub ncaws SiC tsis tshua muaj qhov chaw nyob hauv qhov chaw, txo qis qhov tsis xws luag uas ua rau kub hnyiab lossis xeb.
Txo Residue
Tsawg silica thiab carbon cov ntsiab lus txo cov tshuaj residue, ua kom lub ntsej muag huv si npaj rau qhov kawg polishing lossis txheej.
Predictable Material Tshem Tawm
Kev hnav khaub ncaws zoo ib yam tswj xyuas qhov kev tshem tawm tsis tu ncua, muab cov neeg ua haujlwm tswj xyuas qhov tseeb ntawm qhov kawg thiab qhov tseeb.
Cov txiaj ntsig zoo no yog qhov tseem ceeb hauv kev siv qhov twgnanometer-scale nto zoo txiav txim qhov ua tau zoo - xws li, semiconductor wafers, laser optics, kho mob cog, thiab high-end hlau pwm.
5. Kev cuam tshuam cuam tshuam thoob plaws kev lag luam
Optical Components: 90% SiC tawm tsawg dua qhov chaw tawg, ua rau lub teeb kis tau zoo dua thiab MTF (Modulation Transfer Function).
Hlau (Stainless Steel, Aluminium, Copper Alloys): Cov tshuaj ntxuav kom huv yuav txo tau qhov kev pheej hmoo ntawm kev xeb tom qab polishing thiab txhim kho txheej adhesion.
Ceramics & iav: Minimizes subsurface puas, cia polishing kom ua tiav qhov tseeb flatness thiab deg kev ncaj ncees.
Piv txwv li:
Lub chaw tsim khoom siv kho qhov muag ua tau laser lo ntsiab muag hloov ntawm 88% mus rau 90% SiC (tib yam grit) rau qhov kawg lapping:
Txo nto haze los ntawm70%hauv kev xeem kis.
Txiav rework hla dhau50%, txuag lub sijhawm ntau lawm.
Improved first‑pass yield to >95%.
