Yuav Ua Li Cas Kuv Xaiv Txoj Cai Pom Hniav

Ua kom du, nyab xeeb txiav nrog koj lub rooj pom, radial-arm saw, chop saw lossis zawv zawg sib xyaw miter pom nyob ntawm qhov muaj cov hniav zoo rau lub cuab yeej thiab rau hom kev txiav koj xav ua. Tsis muaj qhov tsis txaus ntawm cov kev xaiv zoo, thiab qhov ntim me me ntawm cov hniav tuaj yeem xav tsis thoob txawm tias tus neeg ua haujlwm paub txog ntoo.

Hom saw yuav siv li cas? Qee cov hniav yog tsim los siv rau hauv cov saws tshwj xeeb, yog li koj yuav xav kom tau txais cov hniav zoo rau cov cuab yeej. Kev siv cov hniav tsis zoo rau cov saw yuav ua rau cov txiaj ntsig tsis zoo thiab tej zaum yuav muaj kev phom sij.

Cov ntaub ntawv dab tsi yuav siv los txiav? Yog tias koj xav tau txiav ntau yam khoom siv, qhov ntawd yuav cuam tshuam rau koj xaiv. Yog tias koj txiav ntau hom khoom siv (melamine, piv txwv li) qhov tshwj xeeb kuj yuav cuam tshuam rau koj xaiv.

Saw Blade Essentials Ntau cov saw hniav yog tsim los muab lawv cov txiaj ntsig zoo tshaj plaws hauv kev ua haujlwm txiav. Koj tuaj yeem tau txais cov hniav tshwj xeeb rau ripping lumber, crosscutting lumber, txiav veneered plywood thiab panels, txiav laminates thiab yas, txiav melamine thiab txiav cov hlau tsis muaj hlau.

Ntau cov saw hniav yog tsim los muab lawv cov txiaj ntsig zoo tshaj plaws hauv kev ua haujlwm txiav. Koj tuaj yeem tau txais cov hniav tshwj xeeb rau ripping lumber, crosscutting lumber, txiav veneered plywood thiab panels, txiav laminates thiab yas, txiav melamine thiab txiav cov hlau tsis muaj hlau. Kuj tseem muaj lub hom phiaj dav dav thiab kev sib xyaw ua ke, uas yog tsim los ua haujlwm zoo hauv ob lossis ntau hom kev txiav. (Kev sib xyaw cov hniav yog tsim los hla thiab rips.

Lub hom phiaj dav dav yog tsim los ua txhua hom kev txiav, suav nrog hauv plywood, laminated wood thiab melamine.) Qhov twg cov hniav zoo tshaj plaws yog txiav txim siab, ib feem, los ntawm cov hniav, qhov loj ntawm gullet, cov hniav teeb tsa thiab cov nuv angle (lub kaum sab xis ntawm tus hniav).

Feem ntau, cov hniav uas muaj cov hniav ntau tshaj tawm ib qho kev txiav smoother, thiab cov hniav uas muaj cov hniav tsawg dua tshem cov khoom sai dua. Ib tug 10 "cov hniav tsim los rau ripping lumber, piv txwv li, feem ntau muaj tsawg li 24 cov hniav thiab yog tsim los kom sai tshem tawm cov khoom raws li ntev ntawm cov nplej. Lub rip hniav tsis yog tsim los ua ib daim iav-nkig, tab sis ib tug zoo rip hniav yuav txav los ntawm hardwood nrog me ntsis kev rau siab thiab tawm ib tug huv txiav nrog tsawg kawg nkaus qhab nia.

Ib qho hlais hlais, ntawm qhov tod tes, yog tsim los tsim kom muaj kev sib tw hla cov nplej ntawm cov ntoo, tsis muaj splintering lossis tearing. Hom hniav no feem ntau yuav muaj 60 mus rau 80 cov hniav, thiab cov hniav ntau dua txhais tau tias txhua tus hniav yuav tsum tshem tawm cov khoom tsawg dua. Lub hlais hlais ua rau ntau tus neeg txiav ntau dua li nws txav mus los ntawm cov khoom lag luam dua li cov hniav ripping thiab, vim li ntawd, yuav tsum tau noj qeeb qeeb. Qhov tshwm sim yog kev ntxuav kom huv ntawm cov npoo thiab ib qho smoother txiav nto. Nrog rau qhov zoo tshaj plaws crosscut hniav, txiav nto yuav tshwm polished.

Lub gullet yog qhov chaw nyob rau pem hauv ntej ntawm txhua tus hniav kom tso cai rau tshem tawm nti. Hauv kev ua haujlwm ripping, tus nqi pub yog nrawm dua thiab cov nti loj dua, yog li lub gullet yuav tsum tau sib sib zog nqus txaus rau cov khoom loj uas nws yuav tsum tau ua. Nyob rau hauv ib tug crosscutting hniav, chips yog me me thiab tsawg dua ib tug hniav, yog li ntawd lub gullet yog ntau me me. Cov gullets ntawm ib co crosscutting blades kuj yog lub hom phiaj me me los tiv thaiv tus nqi noj ntau dhau, uas tuaj yeem ua teeb meem tshwj xeeb tshaj yog ntawm radial-arm thiab zawv zawg miter saws.Cov gullets ntawm cov hniav sib xyaw yog tsim los tswj ob qho tib si ripping thiab crosscutting. Cov gullets loj ntawm cov pab pawg ntawm cov hniav pab tshem tawm qhov loj ntawm cov khoom tsim tawm hauv ripping. Cov gullets me me nruab nrab ntawm cov hniav uas ua rau muaj kev cuam tshuam sai heev hauv kev sib tsoo.

Circular sawblades tuaj nrog ntau yam ntawm cov hniav suav, txhua yam ntawm 14 txog 120 cov hniav. Txhawm rau kom tau txais kev txiav kom huv, siv cov hniav nrog tus lej ntawm cov hniav kom raug rau daim ntawv thov. Cov khoom raug txiav, nws cov thickness, thiab cov kev taw qhia ntawm cov nplej txheeb ze rau sawbade pab txiav txim seb cov hniav zoo tshaj plaws. Tej zaum qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub sawb yog qhov xav tau. Cov hniav uas muaj cov hniav qis dua yuav txiav sai dua li cov hniav nrog cov hniav ntau dua, tab sis qhov zoo ntawm qhov txiav yog rougher, uas tsis muaj teeb meem yog tias koj yog tus ncej. Ntawm qhov tod tes, cov hniav uas muaj cov hniav ntau dhau rau ib daim ntawv thov yields qeeb qeeb uas xaus rau hlawv cov khoom, uas tsis muaj tus neeg tsim khoom yuav zam.

Cov hniav nrog tsawg li 14 hniav txiav sai, tab sis roughly. Cov hniav no rhuav tshem txawm tias cov khoom hnyav tshaj plaws nrog kev yooj yim, tab sis lawv siv tsawg. Yog tias koj sim txiav cov khoom nyias nyias nrog cov hniav uas muaj tsawg dua 24 cov hniav, koj yuav pulverize cov khoom.

Ib tug dav framing hniav.tus uas los nrog feem ntau 71.4-hauv. ncig saws.muaj 24 cov hniav thiab muab ib tug zoo nkauj rip txiav tab sis ib tug rougher crosscut. Yog hais tias koj nyob nraum framing nrog 2x Tshuag, qhov precision thiab huv si ntawm kev txiav yog theem nrab kom ceev thiab yooj yim ntawm txiav, nws tej zaum yuav tsuas yog cov hniav koj yuav tsum tau.

Ib tug 40-hlau hniav ua haujlwm zoo rau feem ntau txiav los ntawm plywood. Cov hniav uas muaj 60 lossis 80 hniav yuav tsum tau siv rau ntawm veneered plywood thiab melamine, qhov twg cov veneers nyias zoo li yuav tshuab tawm rau hauv qab ntawm qhov txiav, ib tug yam ntxwv hu ua tearout. MDF yuav tsum muaj cov hniav ntau dua (90 txog 120) kom tau txais kev txiav kom huv.

Yog tias koj ua tiav ntau txoj haujlwm - txhim kho cov yas molding, piv txwv li - koj xav tau kev txiav ntau yam uas yuav tsum tau muaj cov hniav ntau dua. Txiav miters yog qhov pib hla ntawm lub kaum sab xis, thiab cov hniav nrog cov hniav ntau dua feem ntau ua tau zoo tshaj plaws thaum txiav hla cov nplej. Cov hniav nrog 80 lossis ntau dua cov hniav muab cov miter txiav uas koj tab tom nrhiav.
