Phau Ntawv Qhia Txog Qhov Pom Hniav thiab TPI

TPI
	TPI sawv cev rau "cov hniav ib nti" thiab yog ib txoj hauv kev los ntsuas qhov zaus ntawm cov hniav ntawm lub saw hniav. Feem ntau luv luv rau TPI, xws li "ib rab hniav uas muaj 18TPI".
	TPI cuam tshuam li cas lub qhov txiav? TPI ntawm lub qhov pom tuaj yeem cuam tshuam: 1. Nws tuaj yeem txiav ceev npaum li cas
	2. Qhov zoo ntawm kev txiav tiav, xws li du lossis ntxhib.
	3.Material uas yog qhov zoo tshaj plaws rau kev txiav
Txiav ceev thiab zoo
	Tus naj npawb ntawm cov hniav ib nti txawv ntawm hom rau ib hom, tab sis feem ntau yog nruab nrab ntawm 3 thiab 14 TPI.
	Raws li txoj cai dav dav, qhov tsawg dua cov hniav ib nti ib lub qhov pom muaj, qhov ceev nws yuav txiav los ntawm ib qho workpiece. Txawm li cas los xij, vim tias cov hniav loj dua thiab rougher, lawv feem ntau yuav tsim kua muag los ntawm cov fibers ntawm cov khoom uas koj txiav thiab xaus nrog ib qho rougher nto. Qhov no yuav zoo rau cov haujlwm uas qhov tseeb ntawm lub qhov tsis tseem ceeb thiab qhov twg nws yuav tsis pom tom qab ua tiav.
	Cov hniav ntau dua qhov pom muaj, qhov qeeb qeeb nws yuav txiav los ntawm lub workpiece. Txawm li cas los xij, vim tias cov hniav me me thiab nyias, lawv tsis tshua muaj peev xwm tsim kua muag los ntawm cov khoom siv fiber ntau thiab yog li qhov kawg txiav yuav smoother. Ib lub qhov zoo dua yog xav tau rau cov haujlwm uas lub qhov yuav pom thiab qhov tseeb yog qhov yuav tsum tau ua, xws li ua qhov rau ib txheej ntawm cov xauv.
	Tsawg TPI qhov pom (1-4 hniav ib nti) Tsawg TPI pom cov hniav zoo li muaj cov hniav loj dua nrog cov kab noj hniav sib sib zog nqus ntawm lawv. Cov saws no txiav sai sai tab sis muaj kev txhoj puab heev, tawm hauv qhov chaw ntxhib ntawm lub workpiece.
	Qhov saws nrog nruab nrab TPI (5-9 hniav ib nti) Pom cov hniav nrog nruab nrab TPI zoo li qhov sib npaug ntawm qhov nrawm, nruj sawing thiab qeeb, du sawing.
	High TPI Qhov Pom Hniav (10+ TPI) Pom cov hniav nrog tus nqi TPI siab yuav muaj cov hniav me me nrog qhov sib txawv me me ntawm lawv. Cov saws no yuav txiav maj mam tab sis ua rau nyias nyias thiab smoother txiav.
Kev ntsuas TPI
	Txhawm rau nrhiav TPI ntawm cov saw hniav, pib ntsuas los ntawm nruab nrab ntawm txoj hlab pas (feem ntau nws qhov qis tshaj plaws). Tsis muaj teeb meem pes tsawg tus hniav ib nti los ntawm qhov no, qhov ntawd yog pes tsawg tus hniav ib nti koj lub qhov pom muaj.
	Nws yog ib qho tsim nyog sau cia ntawm no tias tsis yog txhua lub voj voog saws muaj ib tus lej ntawm cov hniav ib nti. Qee lub qhov saws yuav muaj 3 ½ kauj ruam ib nti, piv txwv li.
	Nws tseem tsim nyog sau cia tias qee qhov sib txawv pitch qhov saws oscillate thiab yuav muaj tus lej sib txawv ntawm cov hniav ib nti piv rau cov ntiv tes tom ntej raws cov hniav saws. Piv txwv li, qhov no tuaj yeem qhia tau tias yog 4/6 TPI. Qhov no txhais tau tias nws muaj 4 mus rau 6 hniav ib nti.
Cov ntaub ntawv
	Nws yog ib qho nyuaj rau hais nrog qhov tseeb tias ib qho TPI yog qhov tsim nyog rau kev txiav cov khoom siv, vim lwm yam tseem ceeb yuav tsum tau muab coj los rau hauv tus account, xws li cov khoom siv los ntawm cov hniav ntawm lub qhov pom. Yog xav paub ntxiv txog qhov twg lub qhov saws yog qhov zoo tshaj plaws rau kev txiav cov ntaub ntawv, saib nplooj ntawv npe: Dab tsi yog hom ntawm qhov saws?
Qhov pom hniav
	Cov hniav ntawm qee qhov qhov saws feem ntau yog tsim los ntawm lossis coated nrog cov khoom siv los txhim kho lawv cov khoom ua haujlwm. Feem ntau los txhim kho hardness, hnav tsis kam thiab txiav peev xwm. Yog xav paub ntxiv mus saib nplooj ntawv npe: Cov khoom siv twg los xaiv?
	Serrated / square hniav Daim txhuam cev lossis cov hniav plaub fab sib txawv me ntsis ntawm cov qauv pom cov hniav, tab sis koj tseem tuaj yeem txiav txim siab lawv TPI (cov hniav ib nti) los ntawm kev ntsuas ib nti los ntawm nruab nrab ntawm nws lub trough (feem ntau yog qhov qis tshaj) thiab suav pes tsawg cov hniav poob rau hauv nti. . Cov duab tshwj xeeb no qhia tau hais tias lub qhov pom ntawm qhov pom nrog 3TPI. Serrated los yog square hniav core saws thiab cov tub ntxhais xyaum yog tsim los txiav cov ntaub ntawv nyuaj xws li pob zeb, masonry, ceramic pobzeb, iav thiab pob zeb.
