Cov hmoov dawb corundum ua li cas thiaj txuas ntxiv lub neej ua haujlwm ntawm cov cuab yeej?
Dab tsi yog qhov mob tshaj plaws hauv qhov qhuavtxiav thiab sib tsookev lag luam? Nws tsis yog qhov nce nqi hluav taws xob lossis qhov nyuaj ntawm kev ua haujlwm, tab sis cov cuab yeej uas tuag sai dhau! Cov log sib tsoo, cov siv xuab zeb, cov pob zeb roj, cov disc sib tsoo ... cov txiv neej no uas ua neej nyob yuav "poob" hauv ob peb hnub, thiab hloov lawv nrog cov tshiab zoo li txiav nqaij. Tshwj xeeb tshaj yog thaum ua cov khoom siv pob txha tawv - hlau tsis xeb, cov hlau kub siab, thiab cov hlau tawv, cov cuab yeej hnav sai heev uas koj tsis ntseeg koj lub neej.
Nyob zoo cov phooj ywg qub, hnub no cia peb tham txog qhov me me uas tsis pom tseeb no,hmoov corundum dawb, tau dhau los ua ib qho tshuaj kho mob rau "ua kom cov cuab yeej siv tau ntev dua"? Kuv tsis tau hais ntau dhau. Yog tias koj siv nws zoo, nws tsis yog qhov txawv txawv uas yuav ua rau cov cuab yeej siv tau ntev dua ob npaug, thiab cov nyiaj txuag tau yog cov nyiaj tiag tiag!
"Blunt? Kuv mam kho rau koj!" - Tus khawv koob "ua kom ntse" zoo nkauj
Xav txog: ib txheej ntawm cov noob abrasive rau ntawm qhov chaw ntawm lublub log sib tsooyog blunted, thiab qhov ua tau zoo txo qis. Lub sijhawm no, yog tias cov qauv sib tsoo log tau faib sib npaug nrog cov hmoov corundum dawb zoo, lawv zoo li "pab pawg khaws cia".
Thaum cov ntaub nplaum raug hnav kom zoo raws li qhov kev sib tsoo thiab kev sib txhuam cua sov, cov hmoov me me no muaj lub sijhawm los "qhia lawv lub taub hau" thiab hloov cov hmoov loj loj ntawd kom rov ua kom cov hniav ntse!
Qhov no ua rau qeeb qeeb ntawm tag nrho cov log sib tsoo uas "ua tiaj tiaj", ua rau lub log sib tsoo tseem ntse rau ib lub sijhawm, lub zog txiav tsis lwj, thiab kev ua haujlwm zoo ruaj khov. Peb lub Hoobkas sib tsoo ib pawg ntawm cov hlau alloy muaj zog siab, siv cov log sib tsoo ceramic sib xyaw nrog W10 micro-hmoov. Piv nrog cov log sib tsoo ib txwm, nws yuav siv sijhawm ze li ntawm 30% ntau dua los sib tsoo ua ntej nws yuav tsum tau txiav. Tus thawj coj zoo siab heev.
Tus yuam sij rau kev siv cov hmoov me me los txuas lub neej yog nyob rau hauv "kev sib phim" thiab "siv"
Hmoov me me yog ib yam zoo, tab sis nws tsis yog ib yam khoom kho tau txhua yam, thiab nws tsis yog ib yam dab tsi uas siv tau los ntawm kev muab nws tso rau hauv ib qho chaw xwb. Yog tias koj xav kom nws ua lub luag haujlwm zoo kawg nkaus ntawm kev ua kom lub neej ntev, koj yuav tsum tau them sai sai rau:
Xaiv tus "khub" zoo (kev sib phim qhov loj ntawm cov khoom me me): Qhov loj ntawm cov khoom me mehmoov me me (Tus lej W) yuav tsum phim qhov loj ntawm cov khoom siv txhuam tseem ceeb (cov khoom me me)! Yog tias nws loj dhau, qhov ua kom puv thiab ntse yuav tsis zoo; yog tias nws me dhau, nws yuav raug qhwv tag nrho los ntawm cov ntawv khi thiab "ua pa tsis taus" thiab yuav tsis ua haujlwm. Txoj cai yooj yim: Nws yog qhov zoo tagnrho rau qhov loj ntawm cov hmoov me me kom txog li 1/5 txog 1/3 ntawm qhov loj ntawm cov khoom siv txhuam tseem ceeb. Piv txwv li, yog tias koj siv cov khoom me me 46 #, nws yog qhov tsim nyog dua los phim W20-W14 hmoov me me.
Kawm txog "dosage" (piv txwv ntxiv): Yuav ntxiv hmoov me me ntau npaum li cas? Qhov cuam tshuam tsawg dhau tsis pom tseeb, thiab ntau dhau yuav ua rau tsis zoo, cuam tshuam rau lub zog ntawm cov binder lossis ua rau lub log sib tsoo tawv dhau. Qhov piv no nyob ntawm kev sim thiab kev paub dhau los, thiab feem ntau yog kho kom haum rau hauv qhov ntau ntawm 10% -30% ntawm tag nrho qhov hnyav abrasive. Cov log sib tsoo resin tuaj yeem ntxiv rau 20% -30%, thiab cov log sib tsoo ceramic feem ntau yog 10% -20% txaus. Tsis txhob hnyav rau cov khoom siv muaj zog!
Xaiv "kev sib ntaus sib tua" (cov cuab yeej siv tau):
Cov khoom siv sib xyaw ua ke (cov log sib tsoo, cov pob zeb roj, cov taub hau sib tsoo): Qhov no yog qhov chaw sib ntaus sib tua tseem ceeb rau kev ua kom lub neej ntawm cov hmoov me me ntev dua! Tshwj xeeb tshaj yog rau cov log sib tsoo nrog cov resin bonds thiab vitrified bonds. Cov mis thiab cov txheej txheem sib tov yog qhov tseem ceeb kom ntseeg tau tias cov hmoov me me tau sib kis sib npaug.
Cov khoom siv txhuam uas muaj txheej (siv xuab zeb, ntawv xuab zeb): Thaum ua cov siv xuab zeb thiab ntawv xuab zeb, ntxiv me ntsis hmoov me me (xws li 5% -15% ntawm tag nrho cov khoom txhuam) rau cov kua nplaum hauv paus thiab cov kua nplaum dhau tuaj yeem txhim kho lub zog tuav ntawm cov khoom txhuam, tiv thaiv cov khoom txhuam kom tsis txhob poob ua ntej lub sijhawm, thiab tseem pab tiv thaiv kev txhaws. Nws zoo heev rau kev ua cov siv sib tsoo raug.
Sib tsoo thiab txhuam cov kua / muab tshuaj txhuam: Siv ncaj qhahmoov av dawb corundumlos npaj cov kua sib tsoo lossis cov tshuaj txhuam polishing rau kev ua tiav zoo heev. Cov khoom me me heev thiab kev sib xws siab ntawm micropowder tuaj yeem tau txais cov nplaim sib xws thiab tsis muaj kev puas tsuaj ntau, thiab cov cuab yeej (polishing pad / log) nws tus kheej hnav qeeb heev.
