Lub saw txias siv lub voj voog saws los txiav hlau. Nws tau txais nws lub npe los ntawm qhov tseeb tias cov saws no hloov cov cua sov rov qab rau hauv cov hniav es tsis yog rau hauv cov khoom raug txiav, yog li tawm hauv cov khoom sib tsoo txias tsis zoo li cov saw abrasive, uas heats li hniav thiab cov khoom txiav.
Feem ntau kev kub ceev hlau (HSS) los yog tungsten carbide-tipped ncig saw hniav yog siv nyob rau hauv cov saws. Nws muaj lub tshuab hluav taws xob thiab lub iav txo lub zog los tswj qhov ceev ntawm cov saw hniav sib hloov ceev thaum tuav lub torque tas li, uas yuav ua rau nws ua tau zoo. Lub tshuab ziab khaub ncaws ua rau lub suab qis thiab tsis muaj qhov ci, plua plav lossis tsis muaj xim. Cov ntaub ntawv uas yuav tsum tau txiav yog clamped mechanically los xyuas kom meej ib tug zoo txiav thiab tiv thaiv dislocation. Cov saws txias yog siv nrog cov dej txias txias uas yuav ua kom cov hniav hniav txias thiab lubricated.
Xaiv txoj cai txias saw hniav yog ib qho tseem ceeb heev los xyuas kom meej qhov zoo tshaj plaws txiav. Muaj cov saw tshwj xeeb los txiav ntoo lossis hlau los xij thiab cov kav dej. Nov yog qee cov lus qhia kom nco qab thaum yuav khaub thuas saw.
Hniav Khoom:Muaj peb homtxias saw hniavhauv paus suav nrog carbon steel, high speed steel (HSS) thiab tungsten carbide tip. Cov pa roj carbon monoxide yog suav tias yog qhov kev lag luam tshaj plaws ntawm txhua tus thiab nyiam rau feem ntau cov haujlwm txiav. Txawm li cas los xij HSS cov hniav yog qhov ruaj thiab ntev ntev dua li cov pa roj carbon steel thaum Tungsten carbide hniav muaj qhov ceev tshaj plaws txiav ceev thiab lub neej ntev ntawm peb hom.
Thickness:Lub thickness ntawm txias saw hniav yog hais txog txoj kab uas hla ntawm lub saw lub mounting log. Rau lub log me me ntawm 6 ntiv tes, koj tuaj yeem xav tau tsuas yog ib rab riam ntawm 0.014 ntiv tes. thinner cov hniav ntau yuav yog lub neej ntawm cov hniav. Nco ntsoov nrhiav qhov tseeb txoj kab uas hla rau cov hniav los ntawm tus neeg siv phau ntawv los yog sab laj nrog tus neeg muag khoom hauv zos rau cov ntaub ntawv tseem ceeb no.
Cov hniav tsim:Nws yog qhov zoo dua los xaiv cov qauv hniav tsim rau cov ntaub ntawv tsis yooj yim thiab cov hom phiaj dav dav. Hla-hlau hniav yog siv rau qhov smoothest thiab ceev tshaj txiav rau cov khoom loj. Hook-tooth units feem ntau yog siv los txiav cov hlau nyias zoo li txhuas.
Pitch Rating:Nws yog ntsuas nyob rau hauv chav tsev ntawm cov hniav ib nti (TPI). Qhov zoo tshaj TPI yog nyob nruab nrab ntawm 6 txog 12, nyob ntawm seb cov khoom siv. Thaum cov ntaub ntawv mos zoo li txhuas xav tau cov hniav zoo nrog TPI siab, cov ntaub ntawv tuab xav tau cov hniav tawv nrog lub suab qis.
Hniav Set Pattern:Cov hniav tsis tu ncua muaj tib cov hniav sib hloov ntawm ob sab ntawm cov hniav. Cov hniav no ua kom cov kev txiav zoo tshaj plaws thiab zoo haum rau kev txiav nkhaus thiab contours. Wavy qauv hniav nrog ntau cov hniav uas nyob ib sab teem rau ntawm ib sab ntawm cov hniav, uas ua ib tug yoj qauv nrog rau cov pab pawg neeg tom ntej ntawm cov hniav teem mus rau sab nraud yog ntev. Cov qauv wavy feem ntau yog siv rau ntawm cov khoom muag muag.
