Precision machining, tsis yog cov ntaub ntawv twg tuaj yeem ua tau precision machined, qee cov ntaub ntawv nyuaj dhau, ntau tshaj qhov hardness ntawm machined qhov chaw, nws muaj peev xwm ua rau lub tshuab tsoo, yog li cov ntaub ntawv no tsis haum rau precision machining, tshwj tsis yog tias nws yog cov khoom tshwj xeeb. ua los ntawm tshuab qhov chaw, los yog laser txiav. Yog li dab tsi yog qhov yuav tsum tau ntawm precision qhov chaw ua khoom siv? Ntawm no peb tuaj ua ke kom to taub.
Rau precision machining cov ntaub ntawv muab faib ua ob pawg, cov ntaub ntawv hlau thiab cov khoom tsis yog xim hlau.
Rau cov khoom siv hlau, qhov hardness ntawm stainless hlau yog qhov loj tshaj plaws, ua raws li cov hlau cam khwb cia, ua raws li tooj liab, thiab thaum kawg txhuas.
Cov txheej txheem ntawm ceramics, plastics thiab lwm yam ntaub ntawv uas tsis yog-metallic belongs rau kev ua.
1, ua ntej ntawm tag nrho cov, qhov yuav tsum tau ntawm cov ntaub ntawv hardness, rau tej lub sij hawm, lub hardness ntawm cov khoom yog qhov zoo dua, tsuas yog txwv rau hardness yuav tsum tau ntawm lub tshuab ua, cov txheej txheem ntawm cov khoom yuav tsis nyuaj heev, yog tias nyuaj tshaj lub tshuab ua tsis tau.
2, qhov thib ob, cov khoom muag muag thiab tawv me me, tsawg kawg yog ib qib qis dua qhov hardness ntawm lub tshuab, tab sis kuj yuav pom tias lub luag haujlwm ntawm cov khoom siv ua tiav yog ua li cas nrog kev xaiv tsim nyog ntawm cov khoom siv rau cov khoom siv tshuab.
Nyob rau hauv luv luv, precision machining ntawm cov ntaub ntawv uas yuav tsum tau los yog ib co, tsis yog dab tsi cov ntaub ntawv uas yog tsim nyog rau kev ua, xws li cov khoom muag heev los yog tawv heev, lub qub tsis tsim nyog rau kev ua, thiab lub tom kawg yog tsis tiav.
Yog li ntawd, ua ntej ua yuav tsum tau them sai sai rau qhov ceev ntawm cov khoom, yog hais tias qhov ceev yog loj heev, sib npaug rau lub hardness kuj loj heev, thiab yog hais tias lub hardness yog ntau tshaj qhov hardness ntawm lub tshuab qhov chaw (tig lub tshuab dhos), nws yog tsis yooj yim sua. kev ua haujlwm, tsis yog tsuas yog yuav ua rau cov khoom puas tsuaj, tab sis kuj ua rau muaj kev phom sij, xws li tig lub cuab yeej ya tawm ntawm kev sib tsoo raug mob. Yog li ntawd, feem ntau hais lus, rau kev siv tshuab, cov khoom siv yuav tsum qis dua qhov hardness ntawm lub tshuab cuab yeej, kom nws tuaj yeem ua tiav.
