Xaiv cov kua txiav

Xaiv cov kua txiav
1. Lub luag haujlwm ntawm kev ua kua
Lub luag haujlwm tseem ceeb ntawm cov kua dej txias thiab lubrication, thiab tom qab ntxiv cov cuab yeej tshwj xeeb, nws kuj tuaj yeem ua lub luag haujlwm tshwj xeeb hauv kev ntxuav cov tshuab, thiab lwm yam los ntawm kev ua neeg vwm.
2. Hom dej txiav
(1) Cov tshuaj queous lub ntsiab ntawm cov kua aqueous yog dej thiab tshuaj, antifungal cov tshuaj, thiab lwm yam txhawm rau txhim kho lub peev xwm ntxuav, koj tuaj yeem ntxiv cov tshuaj ntxuav tu. Rau cov yuag, cov roj-raws li Additives kuj tseem tuaj yeem ntxiv.
(2) Emulsion emulsion yog ib lub milky dawb kua tsim los ntawm kev sib xyaw dej thiab roj emulsified. Cov roj emulsified yog hom tshuaj pleev pob zeb thiab cov roj tsis muaj roj, thiab cov roj tsis muaj roj ntxiv, thiab cov roj thiab cov roj thiab cov roj thiab roj. (3) cov hluavtaws cov dej ua kua dej hluav taws xob yog qhov ua tau zoo siv nyob hauv tsev thiab txawv teb chaws, muaj ntau yam khoom siv tshuaj ntxiv thiab tshuaj ntxiv. Nws muaj qhov txias txias, lubrication, ntxuav thiab tiv thaiv xeb, zoo thermal ruaj khov thiab lub neej ntev.
(4) txiav roj roj roj feem ntau ua lub zog roj, thiab roj zaub, tshuaj ntsuab, roj zaub, cov roj zaub, thiab lwm yam.
(5) Qhov ua kua dej siab dhau los ua cov kua huab siab ua kua tau npaj los ntawm kev ntxiv roj, leej faj, phosphorus thiab lwm yam siab ntxiv rau cov roj ntxhia. Nws tsis ua kom puas lubricating zaj duab xis ntawm qhov kub thiab txias thiab muaj lubricating nyhuv zoo, yog li nws tau siv dav.
(6) Lubricanes Cov roj nplua nyeem cov roj nplua nyeem yog mas Molybdenum Disulfide (Mos,). Lubricating zaj duab xis tsim los ntawm molybdenum discenum disulfide muaj qhov sib txhuam uas tsis tshua muaj kev sib txhuam thiab lub siab melting point (1185 degree). Yog li, nws tsis yooj yim hloov nws lubricating cov zog ntawm cov khoom kub siab thiab muaj peev xwm siab compression, thiab tseem muaj cov tshuaj ruaj khov thiab kub ruaj khov.
3. Xaiv cov kua dej
(1) According to the processing nature of the selection of rough machining, because the machining allowance and cutting amount are larger, therefore, in the cutting process to produce a large amount of cutting heat, easy to make the tool wear quickly, then the temperature of the cutting area should be reduced, so the emulsion or synthetic cutting fluid based on cooling should be selected.
Thaum lub sijhawm ua tiav, txhawm rau txo cov kev sib txhuam ntawm cov chips, workpieces thiab kom cov tshuab ua kom zoo dua qub emulsion yuav tsum tau xaiv.
Hauv ib nrab-kaw Machining (xws li drilling, reaming los yog sib sib zog nqus cov tshuab, tab sis kuj yog cov chips yog yooj yim mus rub lub machined nto. Rau lub hom phiaj no, nws yog ib qho tsim nyog los xaiv cov kua huab ua kom tsis muaj siab los yog lub siab txiav cov roj nrog cov tshuaj nres qis, thiab nce cov dej ntws thiab siab ntawm cov yam txiav.
(2) Xaiv raws li cov khoom siv workpiece
1) rau cov steel seem, emulsion tau xaiv rau ntxhib machining; Vulcanized emulsion yog siv rau ua tiav.
2) Txhawm rau kom tsis txhob zoo nkauj thaiv cov chips thaiv cov khoom txias lossis ua tsis yog kom tshem tawm, txiav cov kua ntau li cam khwb cia hlau thiab nrum txhuas. 7% ~ 10% emulsion lossis kerosene tseem tuaj yeem siv tau. 3) Thaum ua cov hlau uas tsis muaj hlau los yog cov tshuab hluav taws xob tsis zoo, nws tsis yog kev xav kom siv cov kab mob uas muaj cov quav kom tsis txhob xeb ntawm lub workpiece. 4) Thaum ua cov hlau nplaum magnesium, tsis txhob siv cov kua txiav kom tsis txhob muaj kev sib xyaw thiab hluav taws. Yog tias tsim nyog, nws tuaj yeem txias nrog cua compressed. 5) Thaum ua cov ntaub ntawv nyuaj rau cov khoom siv hluav taws xob xws li cov hlau tsis muaj cua sov, 10% ~ 15% dhau kev ua kom muaj roj lossis siab emulsion.
(3) Xaiv raws li cov khoom siv
1) Cov cuab yeej kub ceev, siv emulsion, siv emulsion, siv huab ntawm cov siab emulsion.
2) Rau cov khoom noj cov cuab yeej carbide, txhawm rau kom tsis txhob muaj cov hniav chipping vim yog qhov chaw cua txias thiab cua sov, txiav dej tsis siv. Yog tias cov kua dej tsis siv, nws yuav tsum tau muab nchuav rau txuas ntxiv thiab txaus.
4. Kev siv cov kua txiav rau cnc tshuab cov cuab yeej, kev siv cov kua txiav yog feem ntau siv los ntawm pouring txoj kev. Rau qhov tob lub tshuab machining, tshuab ntawm nyuaj-rau-tshuab cov ntaub ntawv, thiab kev kub ceev lossis high-high-siab txoj kev yuav tsum tau siv. Cov hauj lwm siab ntawm kev txiav kua yog 1-10 MPa, thiab tus ntws ntws yog 50 ~ 150lmin. Txau cua txias yog tseem muaj txoj hauv kev zoo los siv cov kua dej, uas yog atomized los ntawm cov khoom txau nyob rau hauv qhov kev txiav txim siab ntawm kev kub ceev.
