Sib tsoo log yog lub ntsiab cuab yeej rau kev sib tsoo, haum rau kev sib tsoo high-hardness steel xws li high-speed steel, high-carbon steel, hardened steel, thiab alloy steel. Nws yog lub cev ntxeem tau tsim los ntawm abrasives thiab binders. Cov abrasives, binders thiab qhov yog peb lub hauv paus ntsiab lus ntawm kev sib tsoo log. Raws li cov qauv ntawm cov cuab yeej siv tshuab thiab cov kev xav tau ntawm kev sib tsoo, lub log sib tsoo tau muab faib ua lub log sib tsoo thiab ob lub concave sib tsoo log. Ob chav inclined sib tsoo lub log, cylindrical sib tsoo lub log, disc sib tsoo lub log thiab lub tais sib tsoo lub log. Yog li yuav ua li cas xaiv lub hardness ntawm dawb corundum, xim av corundum thiab lwm yam sib tsoo log?
Sib tsoo lub log yog tsim los ntawm cov duab sib txawv thiab ntau thiab tsawg. Vim muaj qhov sib txawv ntawm cov abrasives, binders thiab lub log tsim cov txheej txheem, cov yam ntxwv ntawm kev sib tsoo lub log tuaj yeem sib txawv heev, uas muaj kev cuam tshuam loj heev rau qhov precision, roughness thiab ntau lawm efficiency ntawm cov txheej txheem sib tsoo. Yog li ntawd, lub log sib tsoo tsim nyog yuav tsum raug xaiv raws li qhov xwm txheej tshwj xeeb.
Cov yam ntxwv ntawm kev sib tsoo log yog txiav txim siab los ntawm cov khoom xws li abrasive, particle loj, hardness, binder, cov duab thiab qhov loj me. Peb twb tau them cov teeb meem ntawm abrasive, particle loj thiab binder xaiv. Feem ntau siv abrasives yog dawb corundum, xim av corundum, ntsuab silicon carbide, dub silicon carbide, thiab lwm yam.
Lub hardness ntawm lub sib tsoo log yog hais txog qhov nyuaj ntawm cov abrasive hais nyob rau saum npoo ntawm lub sib tsoo log ntog tawm nyob rau hauv qhov kev txiav txim ntawm kev sib tsoo quab yuam. Lub hardness ntawm lub sib tsoo lub log yog mos, uas txhais tau hais tias lub abrasive nplej ntawm lub sib tsoo log yog ib qho yooj yim mus poob, thiab lub hardness ntawm lub sib tsoo log yog ib qho nyuaj, uas txhais tau hais tias lub abrasive nplej ntawm lub sib tsoo log tsis yooj yim rau poob. tawm. Log hardness thiab abrasive hardness yog ob lub ntsiab lus sib txawv. Tib lub abrasive tuaj yeem ua rau hauv kev sib tsoo log nrog qhov sib txawv hardness, uas feem ntau yog nyob ntawm qhov xwm txheej thiab ntau npaum li cas ntawm cov ntawv khi thiab cov txheej txheem tsim khoom ntawm lub log sib tsoo. Qhov sib txawv tseem ceeb ntawm kev sib tsoo thiab kev txiav yog tias lub log sib tsoo muaj "tus kheej sib tsoo" ua haujlwm. Xaiv lub hardness ntawm lub sib tsoo log yog tiag tiag xaiv tus kheej-sib tsoo ntawm lub sib tsoo log. Vam tias cov abrasive tsis tuaj ntxov ntxov los yog ua npub.
Lub hauv paus ntsiab lus dav dav rau kev xaiv lub hardness ntawm kev sib tsoo log yog: thaum ua cov hlau mos, txhawm rau tiv thaiv cov abrasive los ntawm kev poob ntxov ntxov, lub log nyuaj yog xaiv. Thaum ua cov hlau tawv, txhawm rau ua kom lub ntsej muag abrasive ntog tawm hauv lub sijhawm thiab nthuav tawm cov khoom abrasive tshiab nrog cov npoo ntse (piv txwv li, cov khoom siv tus kheej abrasive), xaiv lub log sib tsoo mos. Qhov qub yog vim tias thaum sib tsoo cov ntaub ntawv mos, kev ua hauj lwm abrasive ntawm kev sib tsoo log hnav maj mam thiab tsis tas yuav poob tawm ntxov; qhov tom kawg yog vim tias thaum sib tsoo cov ntaub ntawv nyuaj, kev ua haujlwm abrasive ntawm kev sib tsoo log hnav sai dua thiab yuav tsum tau hloov kho sai sai. Hauv kev sib tsoo precision, txhawm rau kom ntseeg tau tias qhov sib tsoo raug thiab roughness, yuav tsum siv lub log sib tsoo me ntsis. Cov khoom siv ua haujlwm muaj cov thermal conductivity tsis zoo thiab ua rau kub hnyiab thiab tawg (xws li sib tsoo cemented carbide, thiab lwm yam). Kev xaiv ntawm kev sib tsoo log yuav tsum yog mos.
Cov saum toj no yog cov lus qhia ntxaws txog yuav ua li cas xaiv lub hardness ntawm dawb corundum, xim av corundum thiab lwm yam sib tsoo log. Kuv vam tias koj tuaj yeem xaiv tau yooj yim!
