Cov yam ntxwv thiab kev xaiv ntawm pob zeb diamond hniav
Thaum nws los txog rau cov hniav, kuv ntseeg tias txhua tus paub tias muaj ntau hom hniav ntawm kev ua lag luam niaj hnub no, tab sis thaum nws los txog rau ntau hom pob zeb diamond hniav, nws yuav tsis meej. Pob zeb diamond hniav yog siv rau milling thiab ua ntau yam tsawg hlau. Xws li txhuas, tooj liab, magnesium thiab txhuas alloy, nyuaj alloy txiav cov cuab yeej thiab cov ntaub ntawv tsis yog xim hlau xws li tshuaj fiber ntau plasticized raw cov ntaub ntawv uas muaj zog hnav tsis kam, hlau-raws li cov ntaub ntawv polymer, thiab lwm yam.
Pob zeb diamond yog cov tshuaj lom neeg nyuaj tshaj plaws hauv qhov xwm txheej. Txawm li cas los xij, vim qhov tsis tshua muaj thiab muaj txiaj ntsig ntawm cov pob zeb diamond ntuj, cov pob zeb hluavtaws tau siv los hloov nws los txo cov nqi. Tam sim no, muaj peb qhov chaw ua haujlwm: pob zeb diamond ntuj (ND) thiab hluavtaws polycrystalline pob zeb diamond. , Synthetic polycrystalline pob zeb diamond composite (PDC).
Cov ntsiab lus tseem ceeb hauv qab no yog cov hluavtaws polycrystalline pob zeb diamond hniav, yog li dab tsi yog cov yam ntxwv ntawm cov pob zeb hluavtaws no? Yuav ua li cas xaiv lub pob zeb diamond hniav zoo?
Pob zeb diamond hniav yam ntxwv
1. Pob zeb diamond hniav muaj qhov zoo ntawm lub zog siab, hnav tsis kam, siab thermal conductivity, thiab qis linear expansion coefficient. Nws tuaj yeem siv rau kev ua haujlwm siab ntawm cov ntaub ntawv nyuaj thiab nkig ntawm cov ntaub ntawv tsis yog xim hlau, xws li: siab graphite, cov ntaub ntawv polymer, high-silicon aluminium alloy profiles thiab lwm yam khoom siv hlau. Niaj hnub no, muaj ntau hom pob zeb diamond hniav nyob rau hauv kev ua lag luam, nrog pom tseeb txawv ntawm cov yam ntxwv. Ntau hom pob zeb diamond hniav muaj cov qauv sib txawv thiab siv lub ntsiab.
2. Ntuj pob zeb diamond hniav yog dav siv rau tooj liab, alloy tooj liab, nyiaj, rhodium thiab lwm yam hlau muaj nuj nqis, raws li zoo raws li ultra-high-precision iav iav ua, xws li: hluav taws xob kho qhov muag tiaj tus iav, multi-faceted iav, thiab lwm yam. nws cov muaju muaj ntau yam, thiab tus nqi ntawm cov hniav yog tus nqi kim. Cov yam ntxwv ntawm PCD nyob rau hauv muaj pes tsawg leeg ntawm cobalt. Lub neej kev pab cuam ntawm cov hniav yog 10 mus rau 500 npaug ntawm cov cuab yeej carbide. Nws yog siv rau milling ntau yam tsis tshua muaj hlau, xws li txhuas, magnesium thiab non-metallic cov ntaub ntawv uas muaj zog hnav tsis kam.
Yuav ua li cas xaiv lub pob zeb diamond hniav?
1. Nyob rau hauv tag nrho cov txheej txheem drilling, tus yuam sij yog kev vam khom rau kev txiav ntug ntawm cov hniav, yog li lub sharper lub txiav ntug, nws yog yooj yim dua rau laum. Yog li ntawd, thaum peb xaiv cov hniav, peb yuav tsum xyuas seb qhov txiav ntug yog qhov ntse thiab seb puas muaj qhov khoob khoob.
Muaj ntau hom hniav ntawm kev ua lag luam niaj hnub no. Yog tias lawv muab faib los ntawm cov khoom siv, lawv tuaj yeem muab faib ua cov hlau tsis muaj steel, carbon hlau, thiab ceramics. Qhov tseeb, nws tsis yog tias qhov siab dua lub zog, lub sharper lub txiav ntug, vim hais tias nws kuj muaj feem xyuam rau lub softness ntawm txiav ntug.
Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum paub seb cov khoom siv raw uas koj ua yog tsim nyog rau kev ua cov pob zeb diamond.
2. Thaum lub sij hawm txiav cov txheej txheem, cov hniav yuav tsum tau txiav txim siab heev ceev thiab cuam tshuam quab yuam, yog li cov hniav yuav tsum muaj zog heev compressive zog thiab muaj zog ductility. Kuj tseem muaj ib yam uas peb yuav tsum nkag siab: cov hniav yuav tsum muaj qee qhov kev hnav tsis kam thiab kub tsis kam, vim tias cov hniav yog txiav qee yam khoom thaum siv, yog li nws muaj zog hnav tsis kam tshaj lwm yam.
