Nyob rau hauv peb lub teb chaws, precision machining muaj siab precision thiab siab machining nqi. Nws yog tsuas yog siv nyob rau hauv pej xeem thiab tub rog teb, xws li lub teb chaws tiv thaiv, khoom kho mob, aerospace, thiab cov khoom siv hluav taws xob. Nrog rau kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev lag luam kev tsim kho kom zoo thiab kho dua tshiab, qhov kev thov rau cov khoom siv tshuab machining tseem nce ntxiv, yog li ntawd, nws muaj nuj nqis heev.
Thiab precision machining tsis yog tag nrho cov ntaub ntawv tuaj yeem ua tau, qee cov ntaub ntawv nyuaj dhau, thiab ntau tshaj qhov hardness ntawm machined qhov chaw, nws yog ib qho ua tau rau crumble lub tshuab qhov chaw. Yog li cov ntaub ntawv no tsis haum rau precision machining tshwj tsis yog tias nws yog cov khoom siv tshwj xeeb ua los ntawm cov khoom siv tshuab lossis laser txiav.
Cov ntaub ntawv rau precision machining tuaj yeem muab faib ua ob hom: cov ntaub ntawv hlau thiab cov ntaub ntawv tsis yog hlau. Rau cov ntaub ntawv hlau, lub hardness yog ntau dua rau stainless hlau. Tom ntej no yog cam khwb cia hlau, ua raws li tooj liab, thiab thaum kawg txhuas, thaum ua cov ceramics, plastics, thiab lwm yam yog ua cov ntaub ntawv uas tsis yog-hlau.
Hauv qhov xav tau ntawm cov khoom siv hardness, rau qee lub sijhawm, qhov siab dua ntawm cov khoom siv, qhov zoo dua. Tsuas yog txwv rau qhov yuav tsum tau ua kom tawv tawv ntawm lub tshuab ua haujlwm, cov khoom siv ua haujlwm tsis tuaj yeem nyuaj, yog tias nyuaj dua, cov khoom siv tshuab tsis tuaj yeem ua tiav. Tsis tas li ntawd, cov khoom siv yog mos thiab tawv, tsawg kawg yog ib qib qis dua qhov hardness ntawm lub tshuab qhov chaw. Tsis tas li nyob ntawm lub luag haujlwm ntawm cov cuab yeej ua tiav ua dab tsi nrog lub tshuab qhov tsim nyog xaiv cov ntaub ntawv. Nyob rau hauv luv luv, precision machining yuav tsum tau ntawm cov khoom los yog ib co ntawm cov khoom tsis yog dab tsi cov khoom yog haum rau ua. Piv txwv li, cov khoom muag muag dhau los yog tawv dhau lawm, qhov qub tsis tsim nyog rau kev ua, thiab tom kawg tsis ua tiav.
Thaum ua cov khoom precision nws yuav tsum ua raws li cov kev cai dab tsi?
Thawj yog qhov yuav tsum tau muaj qhov ntev, uas yuav tsum nruj me ntsis ua raws li kev kos duab ntawm cov qauv kev cai rau kev ua haujlwm. Txawm hais tias lub tuam txhab ua cov khoom tsim khoom hauv kev xyaum thiab qhov loj ntawm cov duab kos yuav tsis zoo ib yam, qhov tseeb qhov loj me ntawm qhov ntev ntawm qhov theoretical qhov ntev, yog cov khoom tsim nyog thiab tuaj yeem siv cov khoom.
Thib ob, cov khoom siv yuav tsum tau, ntxhib thiab ua tiav machining yuav tsum tau siv rau cov khoom siv sib txawv, vim cov txheej txheem roughing yog txiav feem ntau ntawm qhov tsis zoo. Lub workpiece nyob rau hauv cov ntaub ntawv ntawm loj pub, txiav qhov tob yuav tsim ib tug loj tus naj npawb ntawm kev nyuaj siab nyob rau hauv lub sab hauv, ces yuav tsis tiav machining. Lub workpiece nyob rau hauv ib lub sij hawm tom qab ua tiav cov txheej txheem yuav tsum nyob rau hauv ib tug ntau dua precision tshuab cuab tam ua hauj lwm kom lub workpiece yuav ncav cuag ib tug high degree ntawm raug.
Ntxiv dua thiab, kev ua tiav ntawm qhov precision feem ntau muaj cov txheej txheem kev kho cua sov thiab kev kho cua sov, kev kho deg yuav tsum tau muab tso rau tom qab precision machining. Thiab nyob rau hauv cov txheej txheem ntawm precision machining, yuav tsum tau txiav txim siab kom tawm ib txheej nyias ntawm thickness tom qab kev kho mob saum npoo, kev kho cua sov yog los txhim kho cov khoom txiav ntawm cov hlau, yog li nws yuav tsum tau muab tso ua ntej machining.
