Qhov sib txawv ntawm cov hniav muaj cov teebmeem tseem ceeb hauv qab no ntawm cov saw hniav rau txiav ntoo:

1. Txawv txiav ceev

2. txawv glossiness

3. Lub kaum sab xis ntawm cov hniav ntawm cov saw hniav nws tus kheej kuj txawv

4. Lub cev hardness, flatness, kawg dhia thiab lwm yam yuav tsum tau ntawm cov saw hniav kuj txawv

5. Kuj tseem muaj qee qhov kev xav tau rau kev ceev ntawm lub tshuab thiab kev pub mis ceev ntawm cov ntoo

6. Nws kuj muaj ntau yam ua rau qhov tseeb ntawm cov khoom siv saw hniav

Piv txwv li, 40-hnub txiav yog tsawg zog-txuag thiab lub suab yuav ntsiag to vim muaj kev sib txhuam me me, tab sis 60-hnub txiav yog smoother. Feem ntau, cov kws ntoo siv 40 cov hniav. Yog tias lub suab qis, siv cov tuab tuab, tab sis nyias nyias yog qhov zoo dua. Qhov ntau ntawm cov hniav, qhov smoother lub sawing profile, thiab lub suab yuav ntsiag to yog tias koj lub tshuab muaj kev ruaj ntseg zoo.

Tus naj npawb ntawm cov hniav ntawm sawtooth, feem ntau hais lus, ntau cov hniav, ntau qhov txiav ntawm ib lub sijhawm, qhov kev ua haujlwm zoo dua, tab sis cov hniav txiav ntau yuav tsum tau siv ntau cov cemented carbide, tus nqi ntawm cov saw hniav. yog siab, tab sis cov sawtooth yog tuab heev, lub peev xwm nti ntawm cov hniav yuav me me, uas yog ib qho yooj yim ua rau cov saw hniav kub; Tsis tas li ntawd, yog tias muaj cov hniav ntau dhau lawm, yog tias tus nqi pub mis tsis sib haum, 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 lub neej kev pab cuam. cov hniav. .
