Nyob rau hauv qhov tsis muaj precision machinery, cov txheej txheem kev ua ib txwm siv los ntawm cov neeg kho tshuab qhov chaw machinists tsis tsuas yog cuam tshuam rau qhov nrawm ntawm cov khoom, tab sis kuj txo qis kev tsim khoom zoo ntawm cov khoom. Txawm li cas los xij, peb paub tias kev ua tau zoo thiab kev ua tau zoo yog lub hauv paus ntawm kev ua lag luam ciaj sia, tshwj xeeb tshaj yog thaum cov lag luam me thiab nruab nrab nce lawv cov xaj, cov ntim ntau lawm yuav tsum ncav cuag tus qauv tsim nyog. Tam sim no tsuas yog precision machining tuaj yeem ua tau raws li tus qauv no hauv peb lub zej zog. Cov txheej txheem ntawm precision mechanical qhov chaw nyob ntawm kev tsim cov cuab yeej siv siab heev, cov khoom siv tau zoo thiab cov khoom siv high-precision automated ntau lawm. Yog li ntawd, cov cuab yeej yog nruab nrog thawj qhov tseem ceeb.
Precision qhov chaw machining thev naus laus zis yog cov txheej txheem ntawm kev qhia cov txheej txheem machining thiab cov txheej txheem kev khiav hauj lwm rau cov khoom. Raws li kev tsim khoom tshwj xeeb, cov txheej txheem tsim nyog thiab cov txheej txheem ua haujlwm ntau dua raug sau rau hauv cov ntaub ntawv txheej txheem hauv daim ntawv sau npe thiab siv los coj cov khoom tsim tawm tom qab kev pom zoo. Cov txheej txheem khiav ntawm precision machined feem feem ntau suav nrog cov txheej txheem ntawm kev ua cov khoom, cov ntsiab lus tshwj xeeb ntawm txhua tus txheej txheem, cov cuab yeej siv thiab cov txheej txheem siv, cov khoom tshuaj xyuas thiab cov txheej txheem tshuaj xyuas ntawm cov khoom, lub sijhawm ntsuas thiab txiav ntim, thiab lwm yam.
Muaj ntau qhov zoo ntawm precision qhov chaw machining, uas tuaj yeem txhim kho kev tsim khoom thiab kev ua haujlwm zoo, muaj txiaj ntsig pub ntau thiab txo cov nqi lag luam. Precision manufacturing thiab processing thev naus laus zis kuj tseem tuaj yeem txhim kho kev ua haujlwm, txo lub sijhawm ua haujlwm, txo kev siv zog thiab txhim kho kev ua haujlwm zoo. Tsis tas li ntawd, precision machining tuaj yeem txo cov neeg ua haujlwm ntau dua thiab qhov chaw xauj tsev, ua kom lub voj voog ntau lawm, txo cov nqi thiab txuag hluav taws xob. Yog li ntawd, daim ntawv thov ntawm precision machining tshuab muaj ntau yam txiaj ntsig.
Precision machining ntawm txhua yam khoom siv tsis siv neeg tshawb nrhiav thiab saib xyuas cov cuab yeej, uas yuav pab txhim kho cov khoom tsim tawm thiab ruaj khov ntawm cov khoom, thiab hloov tau yooj yim automated ntau lawm tuaj yeem hloov kho cov khoom hloov pauv sai. Yog li ntawd, qhov cuam tshuam ntawm precision machining thev naus laus zis ntawm kev tsim khoom lag luam yog qhov ua tau zoo heev, tab sis thawj zaug peev hauv precision machining qhov chaw ua cov cuab yeej thev naus laus zis yuav yog qhov siab. Yog li ntawd, cov neeg siv yuav tsum tau ceev faj thaum xaiv ib tug precision machining chaw tsim tshuaj paus. Lub tshuab ua haujlwm zoo tuaj yeem nqa cov khoom lag luam zoo thiab ua haujlwm tau zoo thiab tuaj yeem txo tus nqi tag nrho.
Nto roughness ntawm mechanical qhov chaw machining yog ib qho tseem ceeb kev Performance index qhia txog micro geometric yuam kev ntawm cov khoom siv machining nto, yog lub hauv paus tseem ceeb rau kev ntsuam xyuas qhov zoo ntawm txheej txheej ntawm cov khoom, ncaj qha ntsig txog cov khoom zoo, kev pab cuam lub neej, khoom. nqi. Cov txheej txheem ntawm kev xaiv qhov roughness ntawm cov khoom siv tshuab yog cov txheej txheem suav, cov txheej txheem kuaj thiab cov kev sib piv.
Ib qho kev siv ntau hauv kev tsim machining ntawm cov khoom siv tshuab yog qhov kev sib piv, uas yooj yim, ceev thiab tsim nyog; daim ntawv thov ntawm qhov no yuav tsum tau siv cov ntaub ntawv txaus, thiab cov khoom siv ntau thiab cov ntaub ntawv siv tam sim no tau muab rau hauv ntau yam qauv tsim qauv qhia. Feem ntau, nto tiav yog sib xws nrog qhov ntev kam rau ua theem. Feem ntau hais lus, qhov me dua tus qauv kam rau ua thiab tsim cov khoom siv kho tshuab, qhov me me ntawm qhov roughness tus nqi ntawm cov khoom siv tshuab, tab sis tsis muaj kev sib raug zoo ntawm lawv.
Mechanical qhov chaw machining lub zog yog lub peev xwm ntawm qhov tsis ua kom tawg los yog ua rau ntau tshaj qhov tso cai rau cov yas deformation thaum ua hauj lwm, thiab yog qhov yooj yim muab rau txhua yam kev ua haujlwm thiab kev ruaj ntseg ntawm cov khoom siv. Standard countermeasures los txhim kho lub zog ntawm ib feem yog: nyob rau hauv thiaj li yuav nthuav cov specifications ntawm qhov pheej hmoo cross-section ntawm ib feem, nthuav lub sij hawm ntawm inertia ntawm tus ntoo khaub lig-section, zoo tsim ntawm tus ntoo khaub lig-section ntawm rooj plaub; kev siv cov ntaub ntawv muaj zog, cov khoom siv raw los nthuav cov txheej txheem kev kho cua sov los txhim kho lub zog thiab txo cov kev ntxhov siab thermal, kev ua haujlwm ntawm cov txheej txheem tsim los txo lossis tshem tawm cov kev ua tsis zoo ntawm microscopic, thiab lwm yam.; txhawm rau txo cov load ntawm qhov chaw kom txo tau qhov kev ntxhov siab, thiab lwm yam, cov qauv ntawm cov khoom yuav tsum tau ua kom zoo.
