Qhov zoo machining yog dab tsi? Dab tsi ntawm kev ua yog zoo machinery tsuas yog siv rau? Cov kev cai rau cov ntaub ntawv yog dab tsi? Qhov tseeb machining yog qhov tseeb dua li ntawm cov tshuab zoo tib yam. Cov tshuab uas ncav cuag lossis tshaj 0.1 μ m yog cov tshuab zoo. Feem ntau, kev ua haujlwm zoo yog ua tiav raws li kev tswj hwm ib puag ncig nruj me ntsis los ntawm kev siv cov cuab yeej siv tshuab zoo, cov cuab yeej ntsuas zoo thiab ntsuas. Nws tuaj yeem siv rau cov khoom siv zoo hauv hydraulic thiab pneumatic servo mechanisms ntawm kev lag luam aerospace, thav ntawv thiab plhaub ntawm gyroscopes, huab cua thiab cov kua dej ntab cov kabmob thiab ntab. Cov ntaub ntawv ntawm kev ua haujlwm zoo tuaj yeem muab faib ua ob pawg: cov ntaub ntawv hlau thiab cov ntaub ntawv tsis yog hlau.
Koj puas muaj lus nug txog kev ua haujlwm zoo? Tsis yog txhua cov ntaub ntawv tsim nyog rau kev ua haujlwm nrog cov khoom zoo. Raws li rau cov ntaub ntawv hlau, lub hardness yog nyob rau hauv kev txiav txim ntawm stainless hlau, cam khwb cia hlau, tooj liab thiab txhuas. Kev ua cov ceramics thiab plastics belongs rau kev ua cov ntaub ntawv uas tsis yog xim hlau. Nws yog txwv rau qhov kev thov hardness ntawm cov khoom ua haujlwm. Hauv qee qhov chaw, qhov siab dua tus nqi hardness, qhov zoo dua. Txawm li cas los xij, cov ntaub ntawv ua haujlwm tsis tuaj yeem nyuaj dhau, lossis kev ua haujlwm tsis tuaj yeem nres. Yog li ntawd, nws yog ib qho tsim nyog los xaiv cov khoom tsim nyog rau cov khoom raws li lub luag haujlwm ntawm cov khoom siv ua tiav. Hauv qhov chaw zoo tib yam, nws yog qhov zoo dua los sib piv cov khoom muag muag thiab tawv.
Ua ntej nres zoo machining, koj yuav tsum xyuam xim rau qhov ntom (hardness) ntawm cov khoom xaiv. Yog hais tias lub hardness tau dhau qhov hardness ntawm lub tshuab qhov chaw (cov cuab yeej tshuab dhos), tsis tsuas yog cov khoom yuav tsum machined, tab sis kuj cov khoom yuav puas los yog yuav raug tsim. Piv txwv li, yav dhau los, muaj xwm txheej tig cov cuab yeej ya mus rau hauv thiab ua rau neeg raug mob. Yog li ntawd, rau kev siv tshuab, cov khoom siv yuav tsum qis dua qhov hardness ntawm lub tshuab cuab yeej, kom nws tuaj yeem ua tiav.
Fine machining mas suav nrog zoo tig, zoo tho txawv, nplua milling, zoo sib tsoo thiab sib tsoo. Cov nyhuv: txoj kab ciam teb lossis qhov ua kom ntev ntev ntawm qhov yog qis dua micrometer; Geometric duab thiab kev sib nrig sib txoj hauj lwm raug ncav cuag micron los yog angular thib ob theem; Qhov saum npoo micro unevenness tsawg dua 0.1 μ m; Kev sib nrig sib fittings tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev sib xyaw ua ke thiab cov khoom siv hluav taws xob zoo lossis lwm yam ntxwv ntawm lub cev.
