Hais txog precision machining, tsis yog txhua yam ntaub ntawv tsim nyog. Qee cov ntaub ntawv nyuaj dhau, tshaj qhov hardness ntawm machined qhov chaw, thiab cov khoom yuav tawg. Yog li, cov ntaub ntawv no tsis haum rau precision machining, tshwj tsis yog tias lawv yog cov khoom siv tshwj xeeb, lossis laser txiav.
Cov ntaub ntawv rau precision machining tuaj yeem muab faib ua ob hom: cov khoom siv hlau thiab cov khoom tsis yog xim hlau.
Rauprecision machined hlau cov ntaub ntawvLub hardness yog ntau dua li ntawm cov hlau tsis muaj steel, ua raws li cov hlau cam khwb cia, ua raws li tooj liab, thiab thaum kawg txhuas, thaum ua cov ceramics, plastics, thiab lwm yam belongs rau kev ua cov ntaub ntawv uas tsis yog xim hlau.
Ua ntej, thawj yog qhov yuav tsum tau ua rau lub hardness ntawm cov khoom. Rau qee lub sijhawm, qhov siab dua qhov hardness ntawm cov khoom, qhov zoo dua. Nws tsuas yog txwv rau hardness yuav tsum tau ntawm machined qhov chaw, thiab cov txheej txheem yuav tsum tsis txhob yuav nyuaj heev. Yog tias nws nyuaj dua li cov khoom siv machined, nws tsis tuaj yeem ua tiav.
Qhov thib ob, cov khoom siv yog mos mos thiab tawv, tsawg kawg yog ib qib qis dua qhov hardness ntawm lub tshuab qhov chaw. Nyob rau tib lub sijhawm, nws kuj yog nyob ntawm kev ua haujlwm ntawm cov cuab yeej ua tiav, thiab xaiv cov khoom tsim nyog rau lub tshuab ua haujlwm. Nyob rau hauv luv luv, precision machining tseem muaj qee qhov yuav tsum tau ua rau cov ntaub ntawv, thiab tsis yog txhua yam ntaub ntawv tsim nyog rau kev ua. Piv txwv li, rau cov ntaub ntawv uas yog mos heev los yog tawv heev, lub qub tsis tsim nyog yuav tsum tau ua, thaum lub tom kawg yuav ua tsis tau.
Lub precision machining kev lag luam yeej ib txwm yog ib tug neeg ua hauj lwm-intensive, peev-intensive thiab technology-intensive kev lag luam nrog high kev lag luam pib. Txawm hais tias ib qho kev lag luam dav dav tau tsim tab sis tsis ncav cuag ib qho kev ntsuas, nws nyuaj rau kev tsim cov txiaj ntsig, thiab nws cov kev xav tau rau precision machining yog nruj heev.
Cov txheej txheem ntawm machining precision qhov chaw muaj cov kev cai nruj heev. Kev ua tsis tiav me ntsis thaum lub sijhawm ua haujlwm yuav ua rau qhov kev ua haujlwm yuam kev kom dhau qhov kev ua haujlwm siab, yuav tsum tau rov ua dua, lossis tshaj tawm tias nws muaj qhov tsis zoo thiab muab pov tseg, uas ua rau tus nqi ntau lawm.
Dab tsi yuav tsum tau ua raws li thaum ua cov khoom precision?
Thawj yog qhov yuav tsum tau muaj qhov ntev, uas yuav tsum tau ua tiav nruj me ntsis raws li geometric kam rau ua ntawm cov duab kos, txawm hais tias cov khoom ua tiav thiab tsim los ntawm lub tuam txhab yuav tsis zoo ib yam li qhov ntev ntawm cov duab kos. Txawm li cas los xij, qhov loj me yog nyob rau hauv qhov kam rau ua ntawm qhov loj me, thiab nws yog cov khoom tsim nyog thiab siv tau.
Thib ob, hais txog cov khoom siv, cov khoom siv nrog kev ua yeeb yam sib txawv yuav tsum tau siv rau kev sib tsoo thiab ua tiav. Cov txheej txheem qhuav roughing yog txiav feem ntau ntawm qhov khoob. Thaum tus nqi pub yog loj thiab qhov tob ntawm kev txiav yog loj, lub workpiece yuav tsim ib tug loj npaum li cas ntawm kev ntxhov siab nyob rau hauv, thiab lub sij hawm no nws yuav tsis ua tiav. Thaum lub workpiece tiav tom qab ib lub sij hawm ntawm lub sij hawm, nws yuav tsum tau ua hauj lwm rau ib tug ntau dua-precision tshuab cuab tam, thiaj li hais tias lub workpiece yuav ua tau siab precision.
Thib peb, kev ua tiav ntawm precision qhov feem ntau muaj cov txheej txheem ntawm kev kho deg thiab kev kho cua sov, thiab kev kho deg yuav tsum tau muab tso rau tom qab precision machining. Thiab nyob rau hauv cov txheej txheem ntawm precision machining, nyias txheej thickness tom qab kho deg yuav tsum tau txiav txim siab. Kev kho cua sov yog txhawm rau txhim kho kev ua haujlwm ntawm cov hlau, yog li nws yuav tsum tau ua ua ntej machining.
