Circular saw hniav muaj ob peb txheej ntawm cov xim sib txawv, thiab dab tsi yog qhov zoo thiab qhov tsis zoo ntawm txhua qhov.
Kev xaiv ntawm cov saw saw; Feem ntau siv cov cemented carbide yog tungsten-cobalt (code YG) thiab tungsten-titanium (code YT). Vim muaj kev cuam tshuam zoo ntawm tungsten thiab cobalt carbides, lawv tau siv dav hauv kev lag luam ntoo. Cov qauv uas nquag siv hauv kev ua ntoo yog YG8-YG15. Tus lej tom qab YG qhia qhov feem pua ntawm cov ntsiab lus cobalt. Nrog rau qhov nce ntawm cov ntsiab lus cobalt, qhov cuam tshuam toughness thiab flexural zog ntawm cov hlau yog txhim kho, tab sis lub hardness thiab hnav tsis kam yog txo. Xaiv raws li qhov xwm txheej tiag tiag.
1. 65Mn caij nplooj ntoos hlav steel muaj elasticity zoo thiab plasticity, cov khoom siv nyiaj txiag, kev kho cua sov zoo hardenability, tsis tshua muaj cua sov kub, yooj yim deformation, thiab tuaj yeem siv rau cov saw hniav uas tsis tas yuav tsum tau txiav siab.
2. Cov cuab yeej carbon steel muaj cov ntsiab lus siab carbon thiab siab thermal conductivity, tab sis nws cov hardness thiab hnav tsis kam poob qis thaum raug kub ntawm 200 ℃ -250 ℃, kev kho cua sov deformation loj, hardenability tsis zoo, thiab lub sijhawm tempering. yog ntev thiab yooj yim tawg. Tsim cov khoom siv nyiaj txiag rau cov cuab yeej txiav xws li T8A, T10A, T12A, thiab lwm yam.
3. Muab piv nrog cov cuab yeej carbon steel, cov cuab yeej hlau alloy muaj cov cua sov zoo, hnav tsis kam thiab ua haujlwm zoo dua. Qhov kub distortion kub yog 300 ℃ -400 ℃, uas yog tsim rau kev tsim high-qib alloy ncig saw hniav.
4. High-speed tool steel muaj zoo hardenability, muaj zog hardness thiab rigidity, thiab tsawg tshav kub-resistant deformation. Nws yog ib qho ultra-high-strength steel nrog ruaj khov thermoplasticity thiab yog tsim rau kev tsim high-qib ultra-thin saw hniav.
Txoj kab uas hla ntawm lub voj voog saw; txoj kab uas hla ntawm saw hniav yog hais txog cov khoom siv sawing thiab thickness ntawm sawing workpiece. Txoj kab uas hla ntawm cov saw hniav yog me me, thiab txiav ceev yog qhov tsawg; qhov loj ntawm txoj kab uas hla ntawm cov saw hniav, qhov siab dua qhov yuav tsum tau rau cov saw hniav thiab cov cuab yeej sawing, thiab cov sawing efficiency ntau dua. Sab nraud txoj kab uas hla ntawm cov saw hniav yog xaiv raws li cov qauv sib txawv thiab cov saw hniav nrog tib txoj kab uas hla yog siv.
Cov diameters ntawm tus qauv yog: 110MM (4 nti), 150MM (6 nti), 180MM (7 nti), 200MM (8 nti), 230MM (9 nti), 250MM (10 nti), 300MM (12 nti), 350MM (14 nti), 400MM (16 ntiv tes), 450MM (18 nti), 500MM (20 nti), thiab lwm yam. Cov zawj hauv qab pom cov hniav ntawm lub vaj huam sib luag precision pom feem ntau yog tsim los ua 120MM.
Kev xaiv tus naj npawb ntawm cov hniav ntawm lub voj voog pom; tus naj npawb ntawm cov hniav ntawm cov hniav, feem ntau hais lus, cov hniav ntau dua, cov hniav txiav ntau dua tuaj yeem txiav ib lub sij hawm, thiab qhov kev txiav zoo dua, tab sis tus naj npawb ntawm cov hniav txiav yuav tsum tau ntau carbide, thiab tus nqi ntawm cov saw tus hniav txawm li cas los xij, yog tias lub soob yog ntau dhau, qhov muaj peev xwm nti ntawm cov hniav ua me dua, uas yuav ua rau pom cov hniav los ua kom sov; Tsis tas li ntawd, yog hais tias muaj ntau sawtooths, yog hais tias tus nqi pub yog tsis zoo matched, txiav tus nqi ntawm txhua tus hniav yog heev me me, uas yuav aggravate lub txiav ntug thiab lub workpiece. Kev sib txhuam cuam tshuam rau lub neej ua haujlwm ntawm cov hniav. Feem ntau cov hniav sib nrug yog 15-25 hli, thiab tus naj npawb ntawm cov hniav yuav tsum tau xaiv raws li cov khoom siv sawed.
Lub thickness ntawm lub voj voog; lub thickness ntawm saw hniav Nyob rau hauv txoj kev xav, peb cia siab hais tias lub thinner lub saw hniav, qhov zoo dua, cov saw seam yog tiag tiag ib hom kev noj. Cov khoom siv ntawm cov hlau saw hniav hauv paus thiab cov txheej txheem tsim ntawm cov saw hniav txiav txim siab qhov tuab ntawm cov saw hniav. Yog hais tias lub thickness yog heev nyias, lub sawb yog ib qho yooj yim rau co thaum ua hauj lwm, uas muaj feem xyuam rau cov txiav txiav. Thaum xaiv qhov tuab ntawm cov saw hniav, qhov ruaj khov ntawm cov hniav thiab cov khoom yuav tsum tau txiav txim siab. Lub thickness xav tau rau qee cov khoom siv tshwj xeeb kuj yog qhov tshwj xeeb, thiab yuav tsum tau siv raws li qhov yuav tsum tau ua ntawm cov khoom siv, xws li slotting saw hniav, scribing saw hniav, thiab lwm yam.
1. Cov hniav feem ntau siv yog cov hniav sab laug thiab sab xis (cov hniav sib txawv), cov hniav tiaj tus, cov hniav trapezoidal tiaj tus hniav (cov hniav siab thiab qis), cov hniav trapezoidal inverted (inverted conical hniav), dovetail hniav (hump hniav), thiab cov tsis tshua muaj kev lag luam. qib peb sab laug thiab ib txoj cai, sab laug thiab txoj cai tiaj tus hniav, thiab lwm yam.
2. Lub tiaj tus hniav saw yog ntxhib, txiav ceev yog qeeb, thiab kev sib tsoo yog qhov yooj yim tshaj plaws. Nws yog tsuas yog siv rau sawing ntawm cov ntoo, thiab tus nqi qis. Nws feem ntau yog siv rau txhuas sawb nrog me me diameters kom txo tau adhesion thaum txiav, los yog rau grooving saw hniav kom hauv qab ntawm zawj tiaj.
3. Ladder tiaj tus hniav yog kev sib xyaw ntawm cov hniav trapezoidal thiab cov hniav tiaj tus. Kev sib tsoo yog qhov nyuaj dua. Thaum sawing, nws tuaj yeem txo qhov tshwm sim ntawm veneer tawg. Nws yog tsim rau sawing ntawm ntau yam ib leeg thiab ob chav veneer wood-based panels thiab fireproof panels. Txhawm rau tiv thaiv kev sib tsoo ntawm txhuas sawb, saw hniav nrog ntau tus hniav tiaj tus feem ntau siv.
4. Inverted ntaiv cov hniav feem ntau siv nyob rau hauv qab zawj saw hniav ntawm lub vaj huam sib luag pom. Thaum sawing ob-veneer ntoo-raws li vaj huam sib luag, zawj pom kho qhov tuab kom ua tiav cov txheej txheem grooving ntawm hauv qab saum npoo, thiab tom qab ntawd cov saw tseem ceeb ua tiav cov txheej txheem sawing ntawm lub rooj tsavxwm, kom tiv thaiv cov saw ntug ntawm chipping.
