Feem ntau peb tuaj yeem xaiv raws li qhov kev pom zoo ntawm cov khoom siv tshuab; Thib ob, nws kuj tuaj yeem raug xaiv raws li cov kev paub dhau los. Piv txwv li, thaum siv cov cuab yeej siv high-speed steel rau kev txiav qis, cov kua roj ntshiab hlau txiav cov kua dej feem ntau yog siv, thiab thaum siv cov cuab yeej cemented carbide rau kev txiav ceev, cov dej-soluble hlau txiav cov kua dej feem ntau siv tau; Thaum cov kua dej yog qhov nyuaj lossis cov kua txiav tsis yooj yim mus txog qhov chaw txiav, cov kua roj ntshiab hlau txiav (xws li tapping, puab qhov broaching, thiab lwm yam) tuaj yeem siv. Hauv lwm qhov xwm txheej, dej-soluble hlau txiav cov kua dej feem ntau tuaj yeem siv.
Nyob rau hauv luv luv, tej yam kev txiav kua yuav tsum tau xaiv raws li tej yam kev mob tej yam kev mob thiab yuav tsum tau, cov yam ntxwv sib txawv ntawm ntshiab oily hlau txiav kua thiab dej-soluble hlau txiav kua, thiab qhov sib txawv qhov tseeb tej yam kev mob ntawm txhua lub Hoobkas, xws li Kev ua cua sov ntawm lub rooj cob qhia, cov khoom siv pov tseg kev kho cov kua muaj peev xwm thiab kev siv cov dej txiav hauv cov txheej txheem yav dhau los thiab cov txheej txheem tom ntej.
Thib ob, tom qab xaiv hom kev txiav cov kua dej, hom txiav cov kua dej yuav tsum tau xaiv ua ntej raws li cov txheej txheem txiav, cov khoom siv ntawm cov khoom ua haujlwm yuav tsum tau ua thiab cov kev xav tau rau kev ua haujlwm raug thiab roughness ntawm lub workpiece. Piv txwv li, thaum xaiv kev sib tsoo cov kua dej, peb yuav tsum xav txog tsis tsuas yog cov xwm txheej ntawm kev txiav zoo tib yam nkaus xwb, tab sis kuj yog cov yam ntxwv ntawm cov txheej txheem sib tsoo nws tus kheej: peb txhua tus paub tias kev sib tsoo yog ib qho txheej txheem ntawm kev txiav ib txhij nrog ntau yam cuab yeej. Tus nqi ntawm kev sib tsoo yog me me, thiab lub zog txiav feem ntau me me, tab sis qhov sib tsoo ceev yog siab (30-80m / s), yog li qhov kub ntawm qhov sib tsoo feem ntau yog siab, uas tuaj yeem siab npaum li. 800-1000 degree , Nws yog ib qho yooj yim ua rau lub zos kub hnyiab ntawm qhov chaw ntawm lub workpiece, thiab kev sib tsoo thermal kev nyuaj siab yuav deform lub workpiece, thiab txawm ua rau tawg ntawm lub workpiece.
Nyob rau tib lub sijhawm, vim tias cov txheej txheem sib tsoo yuav tsim ntau cov hlau khib nyiab thiab sib tsoo log grit, uas yuav cuam tshuam rau qhov roughness ntawm lub workpiece; Yog li ntawd, thaum xaiv cov dej-soluble hlau txiav kua rau kev sib tsoo, peb xav tau cov kua txiav kom muaj cua txias zoo, lubrication thiab ntxuav washability. Raws li cov khoom sib txawv ntawm cov khoom ua haujlwm, thaum xaiv cov dej-soluble hlau txiav cov kua dej, peb yuav tsum xaiv cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv. Piv txwv li, thaum txiav high hardness stainless hlau, peb yuav tsum xaiv huab cua siab dej-soluble hlau txiav kua nrog zoo huab siab kev ua tau zoo raws li nws cov yam ntxwv ntawm siab hardness, siab zog thiab nyuaj txiav, thiaj li ua tau raws li qhov yuav tsum tau ntawm huab siab lubrication. kev txiav cov kua hauv cov txheej txheem txiav; Rau cov ntaub ntawv xws li aluminium alloy thiab tooj liab alloy, vim yog cov yam ntxwv ntawm kev ua haujlwm siab thiab kev ua haujlwm ntawm cov khoom siv nws tus kheej, thaum xaiv cov dej-soluble hlau txiav kua, lubricity thiab ntxuav ntawm cov kua txiav yog xav tau ntau dua, thiab lub workpiece tsis tuaj yeem ua. corroded tib lub sijhawm.
