Raws li cov cuab yeej ua haujlwm feem ntau siv hauv kev lag luam ntoo, ntau cov hniav pom cov hniav feem ntau ua rau raug mob rau tib neeg thiab ua rau cov lag luam poob vim kev ua haujlwm tsis zoo ntawm cov neeg ua haujlwm vim lawv cov kev ua haujlwm siab. Yog li yuav ua li cas peb thiaj li txo tau thiab zam qhov xwm txheej zoo li no?

Peb yuav tsum to taub lub saw saw. Lub saw hniav yog tsim los ntawm ntau cov hniav. Cov hniav saws yog cov ntse thiab cov hniav tsis ploj lawm.Saw hniav tsis zoo yog qhov tseem ceeb ntawm kev siv, yog tias muaj cov hniav uas ploj lawm yuav tsum tsis txhob muaj cov hniav tsis tu ncua, thiab hauv cov txheej txheem ua tau zoo, Yog tias lub rooj tsavxwm muaj cov kab nrib pleb, nws yuav tsum tau txiav. Tsis tas li ntawd, qhov kawg ntawm cov saw hniav feem ntau yog xuas nrig ntaus los ntawm cov chaw tsim khoom kom nres qhov tawg. Yog tias tsis muaj qhov tawg, nws tuaj yeem siv tsis tau, tshwj xeeb tshaj yog nyob rau ntawm ntau cov hniav pom.

Ntawm qhov chaw ntawm kev ua kom ntseeg tau tias cov saw hniav ua tau raws li cov xwm txheej saum toj no, peb tuaj yeem pib ua haujlwm. Ua ntej txoj kev sawing ntawm ntoo, nws yog ib qho tsim nyog los xyuas kom meej tias cov saw hniav tig ib txwm, thiab cov ntoo yuav tsum tsis txhob co. Nyob rau hauv cov ntaub ntawv ntawm hardwood knots, pub ntawm ib tug ceev ceev. Kev noj zaub mov ntawm ntau lub ntsej muag pom yog kev noj zaub mov tsis zoo, uas tuaj yeem zam tau.

Thaum qhov kub ntawm cov saw hniav siab dhau lawm, nws yuav tsum tau txias nrog dej txias, thiab qhov ceev ntawm cov saw hniav nrog ib txoj kab uas hla ntawm ntau tshaj 600mm mus txog 2000 rpm, thiab nws yuav tsum tau txias los ntawm kev txau dej. Tom qab ua haujlwm tiav lawm, nias lub pob nres thaum muaj xwm ceev thiab tua lub ntsiab hloov.

Tsis tas li ntawd, yog tias koj tsis siv ntau lub ntsej muag, tab sis siv phau ntawv ua haujlwm, koj yuav tsum tau them sai sai rau kev hloov kho qeeb yog tias txoj kev pom txawv txav, thiab tsis txhob quab yuam rub lub saw hniav kom tsis txhob muaj kev phom sij. Cov cuab yeej siv nrog cov hniav pom pom xav kom cov neeg ua haujlwm thiab cov neeg ua haujlwm cuam tshuam tsis txhob sawv ntawm qhov kev taw qhia ntawm lub zog centrifugal ntsib kev sib hloov ntawm cov saw hniav, thiab caj npab tsis tuaj yeem ua haujlwm hla cov saw hniav.
