Granularity
Pob zeb diamond nquag siv ntau qhov loj me yog nyob hauv thaj tsam 30/35 txog 60/80. Cov pob zeb nyuab dua, cov nplej me me yuav tsum tau xaiv. Vim hais tias nyob rau hauv tib lub siab ceev, qhov zoo tshaj lub pob zeb diamond, lub zog me me nws yog, uas yog qhov zoo rau kev txiav rau hauv cov pob zeb nyuaj. Ib qho ntxiv, feem ntau qhov loj-pom pom cov hniav yuav tsum tau muaj qhov siab pom, thiab qhov coarser particle loj yuav tsum xaiv, xws li 30/40, 40/50; cov kab uas me-pom pom cov hniav muaj cov txiav ua kom tsawg zog thiab xav kom muaj cov pob zeb txiav zoo. Xaiv cov ntawv nplua me me, xws li 50/60, 60/80.
Tswv yim mloog
Cov sib sib zog ntawm pob zeb diamond ntom hais txog qhov ntom ntawm pob zeb diamond faib rau hauv kev sib txig ntawm cov txheej ua haujlwm (qhov ntawd yog, qhov hnyav ntawm pob zeb diamond ib thaj tsam)." Cov Lus Qhia" stipulate tias qhov concentration ntawm 4.4 carats ntawm pob zeb diamond ib lub cubic centimeter ntawm cov ua hauj lwm matrix yog 100%, thiab cov concentration ntawm pob zeb diamond ntawm 3.3 carats yog 75%. Lub suab ntim qhia tau hais txog qhov ntim ntawm pob zeb diamond hauv cov agglomerate, thiab qhia kom meej tias qhov concentration yog 100% thaum lub ntim ntawm pob zeb diamond nyob 1/1 ntawm tag nrho cov ntim. Ua kom cov pob zeb diamond siab yog xav kom ntev lub neej ntawm pom hniav, vim tias nce siab ntxiv txo qhov nruab nrab txiav quab yuam tau ntsib los ntawm txhua lub pob zeb diamond. Tab sis nce lub concentration yuav inevitably nce tus nqi ntawm lub saw hniav, yog li muaj feem ntau yig, thiab cov concentration nce raws li tus nqi sawing nce.
Hardness ntawm cutter taub hau
Feem ntau hais lus, ntau dua qhov nyuaj ntawm phau ntawv, qhov muaj zog nws hnav tsis kam. Yog li no, thaum pom pob zeb tawg, pob zeb khi yuav tsum siab; thaum pom cov pob zeb muag muag, pob zeb tawv yuav tsum muaj tsawg; thaum pom cov pob zeb tawg thiab tawv pob zeb, qhov khi daim tawv yuav tsum muaj ntsis.
Nyhuv
Hauv cov txheej txheem ntawm kev txiav cov pob zeb, lub pob zeb diamond ncig pom hniav yuav raug rau lwm cov khoom sib pauv xws li lub zog centrifugal, sawing quab yuam, thiab saw kub.
Vim tias lub zog ua kom lub zog thiab kub nyhuv, lub pob zeb diamond ncig pom lub cav yog hnav thiab puas.
Yuam nyhuv: Thaum lub txheej txheem sawing, cov hniav saw yog raug rau ntawm cov quab yuam axial thiab tangential lub zog. Vim muaj lub zog hauv qhov kev qhia ncig thiab radial, cov hniav saw yog nthwv dej nyob rau hauv txoj kev taw qhia axial thiab phaj-zoo li cas hauv qhov kev taw qhia radial. Ob hom kev deformation no yuav ua rau lub pob zeb txiav tsis sib luag, lub pob zeb pov tseg, lub suab nrov thiab lub suab nrov ntxiv thaum pom, ua rau lub pob zeb tawg thaum ntxov thiab txo lub neej tawg.
Kev ntsuas kub: qhov kev xav ib txwm ntseeg hais tias cawv ntawm kub ntawm cov txheej txheem pom hniav yog qhov tseem ceeb hauv ob yam: ib qho yog ua rau cov graphitization ntawm lub pob zeb diamond hauv cov agglomeration; lwm qhov yog ua rau cov kev nyuaj siab thermal ntawm lub pob zeb diamond thiab hauv matrix ua rau lub pob zeb diamond tawg ntog ua ntej lub sijhawm dhau los. Cov kev tshawb fawb tshiab qhia tau hais tias lub tshav kub ua kom sov thaum txiav yog tsuas yog hloov mus rau agglomerates. Arc tsam kub tsis dhau, feem ntau ntawm 40 txog 120 ° C. Qhov sib tsoo taw tes qhov kub ntawm cov abrasive nplej muaj ntau dua, feem ntau ntawm 250 thiab 700 ℃. Txawm li cas los xij, lub coolant tsuas yog txo qhov nruab nrab ntawm qhov kub ntawm thaj chaw arc, tab sis muaj cov nyhuv me me ntawm qhov kub ntawm cov neeg ua haujlwm abrasive. Xws li qhov kub thiab txias yuav tsis ua rau cov graphite kom muaj roj carbonized, tab sis yuav hloov qhov kev sib txhuam ntawm cov nplawm tawg thiab cov haujlwm, thiab ua rau muaj kev nyuaj siab ntawm lub pob zeb diamond thiab cov khoom ntxiv, uas yuav ua rau lub hauv paus hloov pauv ntawm qhov tsis ua hauj lwm ntawm cov pob zeb diamond. Cov kev tshawb fawb pom tau tias cov nyhuv kub yog qhov loj tshaj uas cuam tshuam rau pom hniav tawg.
Hnav thiab puas: Vim muaj cov quab yuam thiab qhov kub, lub ntsej muag tawg feem ntau yuav hnav thiab puas tom qab lub sijhawm siv. Cov qauv tseem ceeb ntawm kev hnav ua kom puas yog raws li nram no: hnav tsis zoo, ib feem ntawm kev sib tsoo, thaj tsam loj crushing, ntog, thiab cov tshuab tawm ntawm cov khoom sib txuas nrog tus neeg sawv cev raws txoj kev txiav nrawm. Kev coj tsis zoo: Cov pob zeb diamond sib xyaw tau niaj hnub txhuam tus kheej rau qhov haujlwm, thiab cov npoo sawv mus rau qhov dav hlau, uas plam qhov ua tau zoo thiab nce kev sib txhuam. Lub tshav kub ntawm sawing yuav ua rau nyias txheej ntawm graphitization nyob rau saum npoo ntawm lub pob zeb diamond, uas yuav zoo heev txo qhov nyuaj thiab ua rau hnyav dua hnav: nplaim ntawm cov pob zeb diamond sib xyaw tau hloov pauv kev nyuaj siab, thiab tib lub sijhawm, nws tseem raug rau kev hloov txiav kev ntxhov siab, thiab qaug zog tawg yuav tshwm sim thiab ib nrab tawg, nthuav tawm Ntse tshiab yog qhov tsim qauv hnav zoo; thaj tsam loj hauv kev sib tsoo: cov pob zeb diamond sib xyaw tau cuam tshuam rau kev thauj khoom thaum txiav hauv thiab sab nraud, thiab cov pob zeb loj dua thiab cov khoom siv lead ua kua muaj noj ua ntej; nchuav: sib hloov txiav txim siab ua rau lub pob zeb diamond Cov lus hais tas li nyob hauv tus neeg sawv cev khi kom tsim daws teeb meem. Nyob rau tib lub sijhawm, hnav ntawm daim ntawv cog lus nws tus kheej thiab lub tshav kub ntawm sawing thaum lub sij hawm saw txheej txheem ua rau muag rau kev sib khi. Qhov no txo qhov tuav quab yuam ntawm phau ntawv tuav, thiab thaum lub zog txiav rau ntawm qhov me me ntau dua qhov tuav lub zog, lub pob zeb diamond hais yuav poob tawm. Tsis muaj teeb meem dab tsi ntawm kev hnav zoo hais txog kev thauj khoom thiab qhov ntsuas kub ntawm pob zeb diamond sib cais. Ob qho no nyob ntawm cov txheej txheem sawing thiab cov cua txias thiab lubrication.
