Yuav ua li cas xaiv carbide saw hniav?

Cov cemented carbide saw hniav muaj ntau yam tsis xws li hom alloy cutter taub hau, cov khoom ntawm lub hauv paus, txoj kab uas hla, tus naj npawb ntawm cov hniav, thickness, cov hniav zoo li, lub kaum sab xis, lub qhov taub, thiab lwm yam. muaj peev xwm ua thiab txiav kev ua tau zoo ntawm cov saw hniav. Thaum xaiv cov saw hniav, nws yog ib qho tsim nyog yuav tsum xaiv cov saw hniav kom raug raws li hom, thickness, sawing ceev, sawing kev taw qhia, pub ceev thiab sawing dav ntawm sawing khoom.

(1) Kev xaiv cov cemented carbide hom

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.

(2) Kev xaiv ntawm substrate

1.65Mn caij nplooj ntoos hlav steel muaj elasticity zoo thiab plasticity, cov khoom siv nyiaj txiag, kev kho cua sov zoo harden-muaj peev xwm, tsis tshua muaj cua sov kub, yooj yim deformation, thiab tuaj yeem siv rau cov saw hniav uas yuav tsum tau txiav tsawg.

2. Cov cuab yeej carbon steel muaj cov ntsiab lus siab carbon thiab siab thermal conductivity, tab sis nws hardness thiab hnav tsis kam poob qis heev ntawm 200℃-250 ℃ qhov kub thiab txias, kev kho cua sov deformation yog loj, hardenability tsis zoo, thiab tempering lub sij hawm ntev thiab yooj yim rau 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.

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, thiab nws cov thermoplastic stability yog tsim rau kev tsim high-qib ultra-nyias saw hniav.

(3) Xaiv txoj kab uas hla

Txoj kab uas hla ntawm cov saw hniav yog txuam nrog cov cuab yeej 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 cov vaj huam sib luag precision pom feem ntau yog tsim los ua 120MM.

(4) Xaiv cov naj npawb ntawm cov hniav

Feem ntau hais lus, cov hniav ntau dua, qhov txiav txiav ntau dua tuaj yeem raug txiav hauv ib lub sijhawm, thiab qhov kev ua tau zoo dua yog txiav. Txawm li cas los xij, qhov ntau ntawm cov hniav txiav, qhov ntau cemented carbide xav tau, thiab tus nqi ntawm cov saw hniav yog siab, tab sis cov hniav yog tuab heev. , cov chips ntawm cov hniav ua me me, uas yog ib qho yooj yim ua rau cov saw hniav kom sov; Tsis tas li ntawd, muaj cov hniav ntau dhau lawm, thiab yog tias tus nqi pub mis tsis zoo sib xws, qhov txiav ntawm txhua tus hniav yog me me, uas yuav ua rau muaj kev sib txhuam ntawm ntug txiav thiab cov khoom ua haujlwm thiab cuam tshuam rau lub neej kev pab cuam ntawm kev txiav. ntug. . Feem ntau cov hniav sib nrug yog 15-25 hli, thiab tus naj npawb ntawm cov hniav yuav tsum raug xaiv raws li cov khoom siv sawed.

(5) Kev xaiv ntawm thickness

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 saw hniav thiab cov khoom siv 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 cuab yeej siv, xws li slotting saw hniav, scribing saw hniav, thiab lwm yam.
