Nws yog ib qho tseem ceeb rau kev ua kom cov hauj lwm zoo thiab txo tus nqi ntawm kev ua haujlwm los xaiv cov sawblade vim li cas. Ua raws li qee qhov kev txiav txim siab thaum xaiv sawbade:
1) Qhov tseem ceeb ntawm kev ua cov khoom.Koj tuaj yeem xaiv cov sawb tshwj xeeb rau cov khoom siv pob zeb, pob zeb lossis pobzeb raws li cov khoom sib txawv.
2) Qhov tseem ceeb ntawm lub cev dimension.Xaiv qhov loj thiab style ntawm saw hniav raws li qhov zoo thiab specification ntawm cov ntaub ntawv txiav.Piv txwv li, txoj kab uas hla ntawm round saw hniav yuav tsum peb zaug tshaj lub txiav workpiece.Tib lub sij hawm, xaiv cov Cov txheej txheem ntawm cov saw hniav raws li qhov yuav tsum tau ua ntawm machining raug .Nws txhais tau tias xaiv nqaim-qhov los yog ua tiav sawtooth saw hniav thaum tus txiav nto yuav tsum tau los yog ua cov khoom thinner thiab tsis yooj yim, ntawm qhov tsis sib xws, xaiv dav-qhov saws hniav thaum tus txiav nto tsis nruj me ntsis los yog txiav cov khoom tuab.
3) Qhov tseem ceeb ntawm kev siv cov cuab yeej siv.Yuav kom lav lub neej txiav, hnav cov saw hniav yuav tsum tau kho ntawm cov cuab yeej siv hluav taws xob siab.In thiaj li yuav lav qhov kev ua tau zoo, ntse saw hniav yuav tsum tau kho ntawm cov khoom siv hluav taws xob tsawg. Nws yog qhov zoo dua los xaiv cov saw hniav uas siv tau thaum siv los yog siv cov cuab yeej siv qis, txwv tsis pub xaiv cov saws saws saws rau cov tshiab los yog cov neeg txiav txim siab.
