Yog tias koj nyob rau hauv kev ua lag luam rau cov menyuam saw rau koj cov tshuab ua lag luam, koj tuaj yeem hla cov ntsiab lus "40 cov menyuam saw" thiab "41 cov menyuam saw".Ob hom ntawm cov menyuam saw no feem ntau siv rau hauv ntau daim ntawv thov, tab sis dab tsi raws nraim lawv sib nrug?Hauv qhov blog no, peb yuav tshawb nrhiav qhov sib txawv ntawm 40 thiab 41 cov hlua khi los pab koj txiav txim siab paub txog koj cov kev xav tau tshwj xeeb.
Ua ntej thiab qhov tseem ceeb tshaj plaws, nws yog ib qho tseem ceeb kom nkag siab tias ob qho tib si 40 thiab 41 cov menyuam saw yog ib feem ntawm ANSI (American National Standards Institute) tus qauv cov menyuam saw series.Qhov no txhais tau hais tias lawv tau tsim los rau qhov tshwj xeeb qhov ntev thiab cov qauv zoo, ua rau lawv hloov tau nrog lwm cov ANSI tus qauv cov menyuam saw.Txawm li cas los xij, txawm tias lawv zoo sib xws, muaj qhov sib txawv tseem ceeb uas tau teeb tsa 40 thiab 41 cov menyuam saw sib nrug.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm 40 thiab 41 cov menyuam saw nyob hauv lawv lub suab.Lub suab ntawm cov menyuam saw yog hais txog qhov kev ncua deb ntawm cov chaw ntawm cov pins uas nyob ib sab, thiab nws ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov saw lub zog thiab lub peev xwm thauj khoom.Nyob rau hauv cov ntaub ntawv ntawm 40 cov menyuam saw, lub suab ntsuas ntawm 0.5 ntiv tes, thaum lub suab ntawm 41 cov menyuam saw me me ntawm 0.3125 ntiv tes.Qhov no txhais tau hais tias 40 cov menyuam saw zoo dua rau cov ntawv thov uas yuav tsum muaj zog dua thiab ua haujlwm ntev, thaum 41 cov menyuam saw yuav tsim nyog rau kev siv lub luag haujlwm sib zog.
Ntxiv rau lub suab, lwm qhov tseem ceeb uas yuav tsum tau xav txog thaum sib piv 40 thiab 41 cov saw hlau yog lawv qhov muaj zog tensile.Lub zog tensile yog hais txog qhov siab tshaj plaws ntawm tensile kev nyuaj siab cov khoom siv tuaj yeem tiv taus yam tsis muaj kev tawg, thiab nws yog ib qho tseem ceeb rau kev txiav txim siab ntawm cov hlua khi rau cov hlua khi rau ib daim ntawv thov.Nyob rau hauv dav dav, 40 cov menyuam saw nyhav yuav muaj zog tensile ntau dua piv rau 41 cov menyuam saw, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv lub luag haujlwm hnyav uas cov saw yuav raug rau cov khoom tseem ceeb thiab lub zog.
Tsis tas li ntawd, qhov ntev ntawm tus kheej cov khoom ntawm 40 thiab 41 cov menyuam saw sib txawv me ntsis.Piv txwv li, txoj kab uas hla ntawm cov chais rau ntawm 40 cov menyuam saw feem ntau loj dua li ntawm 41 cov menyuam saw, tso cai rau kev sib cuag zoo dua thiab kev koom tes nrog sprockets.Qhov sib txawv ntawm cov menyuam loj tuaj yeem cuam tshuam rau tag nrho kev ua tau zoo thiab kev ua haujlwm ntawm cov saw hauv ntau yam kev siv.
Lwm qhov kev xav tseem ceeb thaum xaiv ntawm 40 thiab 41 cov menyuam saw yog qhov muaj cov sprockets thiab lwm yam khoom siv.Txij li thaum 40 cov menyuam saw feem ntau siv nyob rau hauv kev lag luam chaw, nws yuav yooj yim dua los nrhiav ntau yam sib xws sprockets thiab accessories rau 40 cov menyuam saw piv rau 41 cov menyuam saw.Qhov no tuaj yeem yog qhov tseem ceeb hauv qee cov ntawv thov uas qhov tshwj xeeb sprocket qhov ntau thiab tsawg yuav tsum tau teeb tsa.
Thaum kawg, kev xaiv ntawm 40 thiab 41 cov menyuam saw yuav nyob ntawm seb qhov kev xav tau tshwj xeeb ntawm koj daim ntawv thov.Yog tias koj xav tau cov hlua khi uas tuaj yeem tuav cov khoom hnyav thiab muab kev ua tau zoo hauv kev xav tau, 40 cov hlua hlua yuav yog qhov kev xaiv zoo dua.Ntawm qhov tod tes, yog tias koj daim ntawv thov suav nrog cov khoom sib zog thiab yuav tsum tau tsim cov saw hlau ntau dua, 41 cov hlua hlua yuav tsim nyog dua.
Nyob rau hauv xaus, thaum 40 thiab 41 cov menyuam saw yog ob feem ntawm ANSI tus qauv series, lawv txawv nyob rau hauv cov nqe lus ntawm suab, tensile zog, tivthaiv qhov ntev, thiab daim ntawv thov haum.Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb hauv kev xaiv txoj hlua rau cov menyuam rau koj lub tshuab thiab khoom siv.Los ntawm kev coj mus rau hauv tus account cov kev cai tshwj xeeb ntawm koj daim ntawv thov thiab xav txog cov yam ntxwv tshwj xeeb ntawm txhua hom ntawm cov menyuam saw, koj tuaj yeem txiav txim siab paub meej uas ua kom pom kev ua haujlwm zoo thiab kev ntseeg tau.Txawm hais tias koj xaiv 40 lossis 41 cov menyuam saw, koj tuaj yeem ntseeg tau tias ob qho kev xaiv yog tsim los ua kom tau raws li qhov zoo tshaj plaws thiab kev ua tau zoo rau koj cov kev xav tau kev lag luam.
