Carbide riam siv nyob rau hauv woodworking txiav muaj ob peb subdivisions, xws li ncig saws, sawb band saws, milling cutters, profilesing riam, thiab lwm yam txiav ntoo, thiab cov cemented carbiade sib raug rau kev txiav cov khoom sib txawv yog teev hauv qab no. Cov hauv qab no teev cov cemented carbides sib haum rau cov khoom sib txawv.

1. Cov rooj tswj hwm particle, ceev cov rooj tsavxwm, thiab cov khoom siv tshuaj pleev cov khoom siv, thiab cov khoom siv hauv ncoo yog qhov nyuaj, cov khoom siv hauv qab yog cov kua nplaum siab thiab yuav muaj qee yam feem ntawm cov impurities nyuaj. Thaum lub sij hawm txiav cov txheej txheem, lub Hoobkas rooj tog yuav tsum nruj me ntsis raws li cov burr ntawm cov seem txiav, yog li cov ntoo boards feem ntau xaiv cemented carbide nrog Rockwell hardness ntawm 93.5-95 degrees. Cov khoom siv ntawm cov hlau feem ntau yog xaiv tungsten carbide nrog cov nplej loj hauv qab 0.8 um thiab cov ntsiab lus qis ntawm binder theem. Nyob rau hauv xyoo tas los no, vim yog kev hloov thiab hloov pauv ntawm cov ntaub ntawv, ntau lub tsev tsim rooj tog tau maj mam xaiv cov pob zeb diamond pom hniav es tsis txhob carbide saw hniav rau txiav hauv vaj huam sib luag hluav taws xob txiav saws. Pob zeb diamond sib xyaw muaj zog dua, thiab nws cov nplaum thiab corrosion kuj zoo dua tahn cemented carbide nyob rau hauv cov txheej txheem ntawm ntoo-raws li vaj huam sib luag txiav. Raws li cov ntaub ntawv txiav kev ua tau zoo, kev pabcuam lub neej ntawm cov pob zeb diamond pom hniav yog tsawg kawg 15 npaug ntawm cov cemented carbiade saw hniav.

2. Khoom ntoo feem ntau yog hais txog txhua hom ntoo cog ntoo. Qhov kev txiav nyuaj ntawm cov ntoo sib txawv tsis yog tib yam. Feem ntau cov chaw tsim riam feem ntau xaiv cov alloys nrog qib ntawm 91-93.5. Piv txwv li, cov pob caus ntawm xyoob thiab ntoo yog ib qho nyuaj, tab sis cov ntoo yog qhov yooj yim, yog li cov alloys nrog hardness saum 93 degrees feem ntau yog xaiv los xyuas kom meej zoo dua sharpness; cov cav nrog ntau cov pob qij txha tsis sib xws thaum txiav, yog li cov hniav Nws yog qhov yooj yim heev los ua chipping thaum ntsib cov pob, yog li cov hlau ntawm 92-93 degrees feem ntau xaiv, uas tsis tsuas yog ua kom muaj qee qhov ntse tab sis kuj muaj qee qhov kev kawm. ntawm kev sib tsoo tsis kam, thaum ntoo nrog ob peb lub pob thiab cov ntoo tsis sib xws, alloys nrog lub hardness saum 93 degrees yuav raug xaiv. Ntev npaum li kev hnav tsis kam thiab kev ua kom zoo yog lav, lawv tuaj yeem txiav tau ntev; cov ntoo qub nyob rau sab qaum teb yuav tsim cov ntoo khov vim yog qhov txias txias thaum lub caij ntuj no, thiab cov ntoo khov yuav ua rau cov ntoo khov. Tsis tas li ntawd, txiav cov ntoo khov khov rau hauv qhov chaw txias heev yog qhov ua rau chipping, yog li qhov no, alloys nrog qhov kub ntawm 88-90 degrees feem ntau yog xaiv rau kev txiav.

3. Cov ntoo tsis huv. Hom ntoo no muaj ntau impurities. Piv txwv li, cov laug cam siv nyob rau hauv cov chaw tsim kho feem ntau muaj cov ntsiab lus ntawm cov cement, thiab cov laug cam dismantled los ntawm cov rooj tog feem ntau muaj cov ntsia hlau los yog cov ntsia hlau, yog li thaum cov hniav sib tsoo nrog cov khoom tawv thaum txiav nws yuav ua rau chipping los yog tawg npoo, yog li txiav xws li. ntoo feem ntau xaiv alloys nrog qis hardness thiab siab dua toughness. Xws li alloys feem ntau xaiv tungsten carbide nrog nruab nrab thiab ntxhib grain loj, thiab cov ntsiab lus ntawm binder theem kuj yog siab. Lub Rockwell hardness ntawm xws li alloys feem ntau yog qis dua 90. Kev xaiv ntawm cemented carbide rau woodworking tej cuab yeej tsis tsuas yog raws li cov yam ntxwv ntawm txiav ntoo, tab sis cov cuab yeej Hoobkas feem ntau kuj ua kev tshuaj ntsuam xyuas raws li nws tus kheej tsim cov txheej txheem, rooj tog khoom Hoobkas. thiab kev khiav hauj lwm tshuab thiab lwm yam kev mob, thiab thaum kawg xaiv cov cemented carbide nrog qhov zoo tshaj plaws txuam.
