Txoj kab uas hla
Lub qhov taub yog qhov tseem ceeb tshaj plaws ntawm lub qhov pom, txiav txim siab qhov loj ntawm qhov nws tuaj yeem ua tau. Nyob ntawm daim ntawv thov, qhov pom txoj kab uas hla tuaj yeem nyob ntawm ob peb millimeters mus rau pua pua millimeters. Woodworking qhov saws feem ntau yog nyob nruab nrab ntawm 15-100 mm, thaum hlau qhov saws feem ntau nyob rau hauv thaj tsam ntawm 10-50 mm.
Ntsis Khoom thiab Hardness
Cov khoom siv taw qhia ncaj qha cuam tshuam rau kev txiav kev ua haujlwm thiab kev pabcuam lub neej. Cov ntaub ntawv muaj xws li siab - steel ceev (HSS), cemented carbide, thiab carbon steel. High - steel ceev yog haum rau kev ua haujlwm tas mus li thiab kev ua cov ntoo tawv, cov cemented carbide muaj kev hnav tsis kam thiab tuaj yeem ua cov ntawv hlau, thaum cov lus qhia carbon steel yog tsim rau kev ua ntoo zoo tib yam. Ntsis hardness feem ntau yog nyob nruab nrab ntawm HRC55–65, nrog siab - cov lus qhia kawg siab dua.
Txoj kev sib txuas thiab laum tshuab Compatibility
Qhov saws feem ntau yog nruab nrog hexagonal shank, round shank, los yog threaded interfaces rau txuas rau hluav taws xob xyaum, sib nqus xyaum, los yog lwm yam khoom siv fais fab. Txoj kab uas hla chuck tau tshaj thiab cov txheej txheem kev teeb tsa yog cov kev ntsuas uas yuav tsum tau lees paub thaum xaiv los xyuas kom meej qhov kev sib hloov ntawm kev sib hloov thiab siab coaxiality.
Txiav ntug Thickness thiab qhov tob ntawm txiav
Qhov txiav ntug thickness thiab qhov tob ntawm txiav txiav txim siab lub qhov phab ntsa zoo thiab machining efficiency. Thicker txiav npoo yog hnav-resistant tab sis muaj kev txiav siab dua; thinner txiav ntug txiav yooj yim dua, tab sis nws yooj yim rau deformation. Qee lub qhov saws tso cai rau qhov tob ntawm kev tswj kev txiav los ntawm kev kho cov ntug txiav los yog ntxiv ib qho kev xyaum ua kom tau raws li qhov xav tau ntawm cov khoom sib txawv thiab qhov tob.
Kev sib hloov ceev ntau yam
Kev sib hloov ceev ntawm lub qhov pom kuj tseem ceeb heev, feem ntau xaiv raws li cov khoom hardness thiab lub qhov taub. Kev sib hloov ceev dua (2000-3000 RPM) tuaj yeem siv rau qhov me me lossis cork, thaum lub qhov loj dua lossis cov phaj hlau yuav tsum muaj qhov sib hloov qis dua (500-1500 RPM) kom tsis txhob hlawv cov khoom siv los yog ua rau cov txiav txiav.
