Ripping saw hniav

Ripping, feem ntau hu ua txiav nrog cov nplej, yog ib qho yooj yim txiav. Ua ntej motorized saws, tes saws nrog 10 los yog tsawg dua cov hniav loj tau siv los ripwood nplooj ntawv sai thiab ncaj raws li qhov ua tau. Lub saw "rips" sib nrug ntawm ntoo. Vim tias koj txiav nrog cov nplej ntawm cov ntoo, nws yooj yim dua li hlais.

Cov yam ntxwv tsom xam

Qhov zoo tshaj plaws ntawm cov saw rau ripping yog lub rooj pom. Cov hniav sib hloov thiab rooj pom laj kab pab tswj cov ntoo raug txiav; tso cai rau kom raug heev thiab ceev rip txiav.

Rip blades yog optimized txiav los ntawm ntoo nrog, los yog raws lis. Feem ntau siv rau kev txiav thawj zaug, lawv tshem tawm cov fibers ntev ntawm cov ntoo uas tsis muaj kev tiv thaiv tsawg dua li thaum txiav hla cov nplej. Siv lub tiaj tus hniav sib tsoo (FTG) tus qauv, cov hniav tsis tshua muaj (10T- 24T), thiab lub kaum sab xis ntawm qhov tsawg kawg yog 20 degrees, lub ripping hniav txiav los ntawm cov ntoo raws cov nplej sai thiab muaj txiaj ntsig zoo nrog tus nqi noj siab.

Ib tug ripping hniav ntawm cov hniav uas tsis tshua muaj kev tiv thaiv tsawg dua thaum txiav ntau dua cov hniav suav siab. Txawm li cas los xij, nws ua rau muaj qhov hnyav hnyav ntawm qhov txiav. Siv cov hniav ripping rau kev txiav hlais, ntawm qhov tod tes, yuav ua rau muaj qhov tsis txaus siab ntawm cov kua muag. Cov hniav no nti tawm ntawm cov ntoo, tsim kom muaj qhov ntxhib, tsis ua tiav. Ib rab riam hlais tuaj yeem siv los ua kom zoo li qhov ntxhib-finish rip txiav. Koj tseem tuaj yeem dav hlau thiab / lossis xuab zeb nws thaum koj ua tiav cov haujlwm.

Lub Hom Phiaj

Rip-txiav ncig saw hniav yog tsim los txiav nrog cov nplej ntawm cov ntoo. Cov hniav yam ntxwv muaj qhov dav gullet, aggressively zoo lub kaum ntse ntse, tsawg cov hniav tshaj lwm yam saw hniav. Lub hom phiaj tseem ceeb ntawm kev tsim qauv yog kom nrawm nrawm ntoo yam tsis muaj kev sib tsoo, thiab yooj yim tshem tawm cov khib nyiab xws li sawdust lossis chipped lumber.

Feem ntau ntawm cov kev sib txawv no los ntawm qhov tseeb tias nws yooj yim dua rau ripe dua crosscut, txhais tau hais tias txhua tus hniav ntawm cov hniav tuaj yeem tshem tawm cov khoom loj dua.

Tus lej hniav

Kom haum rau qhov loj "tom" ntawm cov ntoo, rip cutting blades muaj cov hniav tsawg dua, feem ntau tsuas muaj 18 txog 36 cov hniav. Tus naj npawb ntawm cov hniav tuaj yeem ua tau ntau dua, nyob ntawm qhov pom ntawm txoj kab uas hla thiab cov hniav tsim.

Hlais saw hniav

Crosscutting yog txoj kev txiav hla cov nplej ntawm ntoo. Nws yog qhov nyuaj dua rau kev txiav hauv qhov kev taw qhia no, dua li kev txiav txiav. Vim li no, crosscutting qeeb qeeb dua li ripping. Cov hniav hlais hlais perpendicular rau cov nplej ntawm cov ntoo thiab yuav tsum tau txiav kom huv si tsis muaj jagged npoo. Cov saw hniav tsis yuav tsum tau xaiv kom haum rau qhov txiav.

Tus lej hniav

Crosscut ncig saw hniav feem ntau muaj cov hniav ntau, feem ntau yog 60 mus rau 100. Cov hniav tuaj yeem siv rau kev txiav moldings, ntoo qhib, ntoo thuv lossis txawm tias cov plywood yog cov hniav tshwj xeeb tsis muaj.
Feem ntau cov hlais hlais hlais hlais yog 7-1/4′, 8, 10, thiab 12 nti. Crosscut saw hniav gullets yog me me vim hais tias txhua tus hniav yuav siv sij hawm me ntsis tom ntawm cov khoom, ua rau cov chips tsawg thiab sawdust. Vim tias cov gullets nqaim dua, cov hniav yuav nyob twj ywm nruj dua thiab vibrate tsawg dua.

Qhov txawv

Tab sis txiav tawm tsam cov nplej yog qhov nyuaj dua li cov nplej.
Cov hniav hlais tawm qhov ua tiav zoo dua li cov hniav txiav vim yog cov hniav ntau dua thiab kev co tsawg dua.
Vim tias lawv muaj cov hniav ntau dua li cov hniav sib tsoo, cov hniav hlais kuj tsim kev sib txhuam ntau dua thaum txiav. Cov hniav muaj ntau dua tab sis me dua, thiab lub sijhawm ua haujlwm yuav ntev dua.

General Purpose pom Hniav

Tsis tas li ntawd hu ua universal saw hniav.Cov saws no yog tsim los rau siab ntau lawm tej ntoo, plywood, chipboard, thiab MDF. TCG cov hniav muab hnav tsawg dua li ATB nrog ze li qhov zoo ntawm kev txiav.

Tus lej hniav

Lub hom phiaj dav dav feem ntau muaj 40 cov hniav, txhua tus yog ATB.
Lub hom phiaj dav dav hover ib ncig ntawm 40 cov hniav, feem ntau muaj ATB (alternate tooth bevel) cov hniav, thiab me me gullets. Cov hniav sib xyaw ua ke hover ib ncig ntawm 50 cov hniav, muaj alternating ATB thiab FTG (cov hniav tiaj tus) los yog TCG (triple nti grind) cov hniav, nrog rau nruab nrab gullets.

Qhov txawv

Kev sib xyaw ua ke zoo saw hniav lossis lub hom phiaj dav dav tuaj yeem ua haujlwm feem ntau ntawm cov neeg ua haujlwm txiav ntoo ua.
Lawv yuav tsis huv li cov kws tshwj xeeb rip lossis crosscut hniav, tab sis lawv zoo meej rau kev txiav cov laug cam loj dua thiab tsim kev txiav tsis rov ua dua.

Lub hom phiaj dav dav poob rau hauv 40T-60T ntau yam. Lawv feem ntau muaj ob qho ATB lossis Hi-ATB hniav.
Nws yog ntau yam tshaj plaws ntawm peb saws
