Dej raws li cov kua txiav yog feem ntau txias txias, ntxiv los ntawm lubrication, nrog rau cov kua (aqueous tov) thiab emulsion. Emulsion yog feem ntau siv hauv milling. Roj raws li kev txiav kua yog tsuas yog lubrication, ntxiv los ntawm kev txias, nrog rau cov roj txiav thiab cov roj siab siab. Txiav roj yog feem ntau siv hauv milling.
Emulsion: emulsion yog cov kua mis dawb diluted los ntawm emulsified roj nrog dej. Ib yam muaj fluidity zoo, loj tshwj xeeb tshav kub muaj peev xwm, tsawg viscosity, zoo txias nyhuv thiab tej yam lubricating kev ua tau zoo. Nws yog tsuas yog siv rau kev txiav steel, cam khwb cia hlau thiab non-ferrous hlau.
Txiav roj: txiav roj yog cov roj ntxhia, thiab lwm yam tsiaj, roj zaub thiab cov roj sib xyaw. Cov roj txiav tau zoo lubrication kev ua tau zoo, tab sis nws cov fluidity thiab tshwj xeeb tshav kub muaj peev xwm me me, thiab nws cov cua kub dissipation nyhuv tsis zoo.
Kev txiav cov kua dej yuav tsum raug xaiv kom tsim nyog raws li cov xwm txheej tshwj xeeb xws li cov khoom siv ua haujlwm, cov khoom siv, cov txheej txheem ua thiab cov kev xav tau.
(1) Thaum lub sijhawm ua haujlwm ntxhib, qhov nyiaj txiav yog loj, qhov kub yog tsim, qhov kub thiab txias, thiab qhov yuav tsum tau ua rau qhov zoo ntawm lub tshuab ua haujlwm tsis siab, yog li cov kua txiav raws li qhov txias yuav tsum tau siv. Thaum ua tiav, cov nyiaj siv ua haujlwm me me, cov cua sov tsim me me, cov nyhuv txias tsis siab, tab sis qhov zoo ntawm lub workpiece yog siab, thiab cov milling cutter yuav tsum tau ua kom ntev, yog li cov kua txiav raws li lubrication yuav tsum tau. siv.
(2) Thaum milling brittle cov ntaub ntawv xws li cam khwb cia hlau thiab tooj dag, txiav cov kua feem ntau tsis siv, thiab kerosene, emulsion thiab compressed cua yuav siv tau thaum tsim nyog.
(3) Thaum siv cov carbide milling cutter rau high-speed txiav, feem ntau tsis txhob siv cov kua txiav, siv emulsion thaum tsim nyog, thiab ncuav tsis tu ncua thiab tag nrho ua ntej txiav, thiaj li tiv thaiv cov hniav los ntawm tawg vim txias txias.
Kev xaiv cov kua dej thaum lub sij hawm milling
1. Carbon steel: emulsion thiab dej qab zib yog siv thaum milling ntxhib. Emulsion (feem ntau ntawm 10 feem pua - 15 feem pua ntawm qhov ceev thiab 5 feem pua ntawm kev kub ceev), siab siab emulsion, compound roj, roj vulcanized, thiab lwm yam yog siv thaum lub sij hawm zoo milling.
2. Alloy steel: emulsions thiab siab siab emulsions yog siv thaum lub sij hawm milling ntxhib. Emulsion (feem ntau ntawm 10 feem pua - 15 feem pua ntawm qhov ceev thiab 5 feem pua ntawm kev kub ceev), siab siab emulsion, compound roj, roj vulcanized, thiab lwm yam yog siv thaum lub sij hawm zoo milling.
3. Alloy steel: emulsion, siab siab txiav roj, vulcanization emulsion thiab siab siab emulsion yog siv thaum lub sij hawm ntxhib milling. Chlorinated kerosene yog siv los ua tiav milling, thiab kerosene ntxiv nrog 25 feem pua ntawm cov roj zaub; Kerosene ntxiv 20% turpentine thiab 20% oleic acid, EP emulsion. Vulcanized roj (diesel ntxiv rau 20 feem pua rog thiab 5 feem pua sulfus), siab siab txiav roj.
4. Cam khwb cia hlau: emulsion, phaj nias emulsion thiab dej qab zib yog siv thaum milling ntxhib. Emulsion, siab siab txiav roj thiab cov roj sib xyaw tuaj yeem siv thaum lub sijhawm ua tiav milling.
5. Bronze thiab tooj dag: hom hlau no tuaj yeem ua tiav yam tsis tau txiav cov kua dej, thiab emulsion, sulfur-muaj emulsion, polarization, kua siab thiab emulsion tuaj yeem siv thaum tsim nyog.
6. Aluminium: feem ntau, kev ua txhuas tsis tas yuav tsum tau ua. Yog tias tsim nyog, emulsion thiab cov roj sib xyaw tuaj yeem siv tau. Diesel roj, compound roj, kerosene thiab turpentine yog siv rau milling tiav.
7. Cam khwb cia hlau: feem ntau, txiav cov kua tsis tas yuav tsum tau ua, thiab compressed cua los yog emulsion yog siv thaum tsim nyog. Feem ntau, nws tsis yog siv thaum lub sij hawm zoo milling, thiab compressed cua los yog emulsion los yog siab heev emulsion yog siv thaum tsim nyog.
