Kev txhim kho ntawm kev sib xyaw ua ke sib tsoo abrasive Sib tsoo
Vim tias qhov ua tau zoo ntawm kev txo qis ntawm kev sib tsoo, kev tshawb fawb ntawm kev txhim kho abrasive tau tsim.
Cov sib tsoo tsis tshua muaj zog yog txoj kev sib tw uas tawg pob tawg yog sib dhos nrog cov nplaum thiab ua rau cov cuab yeej tshwj xeeb rau kev sib tsoo ntawm lub grinder. Tsau abrasive sib tsoo tuaj yeem txhim kho kev sib tsoo ntau, yog li ntau cov kws tshaj lij nyob hauv tsev thiab txawv teb chaws muab qhov tseem ceeb rau cov kev sib tsoo tsis sib tsoo, thiab tau ua ntau cov kev tshawb fawb.
Tam sim no, tseem muaj qee qhov teeb meem hauv kev hnav khaub ncaws ntawm cov cuab yeej tsis zoo. Txhawm rau tiv thaiv kev hnav thiab ua kom zoo li qub, lub sijhawm ua haujlwm thiab kev siv dag zog ntawm cov neeg ua haujlwm tau nce ntxiv, thiab cov nqi tsim khoom yog nce ntxiv. Yog li ntawd, nws yog qhov yuav tsum tau txhim kho ntxiv thiab ua kom zoo rau kev sib tsoo ruaj khov txheej txheem sib tsoo.
Txog ntawm kev npaj ua ke ntawm abrasiveAt tam sim no, txawv teb chaws, xws li Tebchaws Asmeskas thiab Nyij Pooj, tau tsim ib hom tshiab ntawm cov yeeb yaj kiab uas tsis muaj kev sib tw zoo, uas ua rau muaj qhov ua tau zoo lapping system rau lapping nyias zaj duab xis, ua rau cov nyhuv polishing ntawm cov khoom tiav thiab zoo ib yam.Muaj plaub lub ntsiab hauv cov qauv ntawm zaj duab xis abrasive:
1 lub hauv paus khoom siv:
Polyester zaj duab xis 857 (PET), nrog qhov loj ntev thiab qhov siab tawv tensile lub zog, nthuav me me, muaj zog thiab tawv, thiab cov teeb meem tuab thiab ruaj khov. Cov tuab txheej txheem ntawm cov khoom siv dag zog yog: 25, 50, 75 μ M. Nrog qhov yuav tsum tau siv tshuab, kev npaj thiab sib tsoo ua tiav ntawm cov pob zeb diamond sib tsoo disk rau iav ua cov tshuaj ntsuam cov zaub yuav tsum yog 14Thin zaj duab xis, zaj duab xis tuab tsis tsim nyog, yog li muaj 7, 10, 12, 23, 27, 30, 37 μ M series.
2 abrasive:
Nyiv feem ntau siv Al 2O 3, SiC thiab lwm yam abrasives, nrog rau Cr 2O 3 (sib tsoo lub taub hau), CeO2, monocrystal thiab polycrystal hluavtaws pob zeb diamond, FeO, thiab lwm yam. Nws yuav tsum muaj cov khoom tawg zoo thiab txawm tias qhov loj me me faib tawm. , uas yuav tsum tau tswj nruj ntawm cov abrasive particle loj faib, yam tsis muaj qhov loj loj. 3M, USAThere muaj plaub yam ntawm cov xoos abrasive uas ua los ntawm kev sib tsoo precision: Al2O3, SiC, cov thawv dag corundum thiab CBN. Tag nrho cov abrasive hais tau raug soj ntsuam zoo thiab siv Nws tuaj yeem siv rau qhov sib tsoo qhuav lossis ntub dej.
3 phau ntawv: feem
ntau yog cov polymer cob thiab ntau lub compound txuas ntxiv. Ethyl amino formate. Thawj ob yog qhov nyuaj tom qab tau kho kom zoo, thiab tom kawg yog qhov muag. Feem ntau, nws yuav tsum thov cov yeeb yaj kiab ob zaug, thawj zaug yog txhawm rau txhawm rau txhim kho qhov nplaum.
4 txheej:
Electrostatic txujci thiab dov txheej txheem yog siv feem ntau. Cov ntawv nyob hauv hom electrostatic. Cov khoom siv hauv paus yog polyester zaj duab xis. Cov khoom siv abrasive yog A12O3 、 SiC。 yob txheej txheej yog qhov tseem ceeb los ntawm kev siv tshuab luam ntawv, abrasive thiab binder mixed roll roll, txheej tuab yog tswj los ntawm cov menyuam, uas yog los kho qhov sib txawv ntawm cov qob ib ce. Tsis tas li ntawd, muaj cov txheej txheem sib xyaw, txoj kev ua txhaum, txoj kev siv roj electroplating thiab Ni plating txoj kev cai lij choj, thiab lwm yam Hauv Nyij Pooj, qhov txwv sab sauv ntawm qhov kub-tiv taus kub ntawm kev sib tsoo zaj duab xis yog qhov kub ntawm polymer sib txuas cov khoom, txog 250 ℃. feem ntau Ntub dej sib tsoo yog saws, thiab cov coolant yog dej thiab roj. Feem ntau, dej tuaj yeem ua tau raws li qhov yuav tsum ua (xws li kais dej). Dej ntshiab yog siv rau qhov tseeb ntawm lub cav, thiab lub teeb ua roj yog siv rau kev sib tsoo aluminium.
Precision sib tsoo siv cov zaj duab xis abrasive yog ntau tshaj li cov cuab yeej siv muaj zog. Nws tuaj yeem txhim kho qhov muaj peev xwm ntau lawm thiab ua kom tau txais txiaj ntsig, tus nqi tsim nyog, zoo yam khoom, nthuav dav ntau lawm, thiab tswj tus txheej txheem sib tsoo tag nrho.
