Txoj kab uas hla ntawm cov saw hniav yog cuam tshuam mus rau cov khoom siv sawing thiab thickness ntawm sawed workpiece. Txoj kab uas hla ntawm cov saw hniav yog me me, thiab txiav ceev yog tus qis; txoj kab uas hla ntawm saw hniav yog loj, thiab qhov yuav tsum tau rau cov saw hniav thiab sawing khoom yog siab, thiab cov sawing efficiency kuj siab. Sab nraud txoj kab uas hla ntawm saw sawxaivtxoj kab uas hlaraws li qhov sib txawv ncig saw tshuab.

Glub zog,qhov ntau tus lej ntawmpomhniav, txiav ntau duamuaj peev xwmnyob rau hauv ib chav tsev lub sij hawm, txiav kev ua tau zooyog zoo dua, tab sis ntau txiav hniav yuav tsum tau siv ntau carbide, tus nqi ntawmsawb yogntausiab.But lub sawtooth yog dens heeve, covqhov chaw ntawmchipsyogme me, uas yuav yooj yim ua rau cov sawb kom sov;In ntxiv, yog tias muaj ntau cov hniav pom, yog tias pubtus nqi tsis sib haum zoo, qhov txiav ntawm txhua tus hniav yuav tsawg heev, uas yuav ua rau muaj kev sib txhuam ntawm qhov txiav thiab cov khoom ua haujlwm, thiab cuam tshuam rau kev pab cuam lub neej ntawm cov hniav. Feem ntau cov hniav sib nrug yog 15-25mm, thiab tsim nyog tus naj npawb ntawm cov hniav yuav tsum tau xaiv raws li cov khoom yuav sawed.

Lub thickness ntawm saw hniav Nyob rau hauv txoj kev xav, peb cia siab tias lub thinner lub saw hniav, qhov zoo dua. Lub sawing kerf yeej yog ib hom kev noj. Cov khoom siv ntawm cov hlau saw hniav hauv paus thiab cov txheej txheem ntawm kev tsim cov saw hniav txiav txim siab qhov tuab ntawm cov saw hniav. Yog hais tias lub thickness yog nyias heev, cov saw hniav yog ib qho yooj yim rau co thaum nws ua hauj lwm, uas yuav cuam tshuam rau cov nyhuv txiav. Thaum xaiv lub thickness ntawm cov saw hniav, lub stability thiab lub txiavcov khoom siv yuav tsum tau txiav txim siab. Lub thickness xav tau rau qee cov khoom siv tshwj xeeb kuj yog qhov tshwj xeeb, thiab yuav tsum tau siv raws li cov khoom siv, xws lizawv zawgsawb, scoringsaws, thiab lwm yam.
