Dab tsi yog precision machining? Nws yog cov txheej txheem ntawm kev hloov pauv qhov loj me lossis cov khoom ntawm lub workpiece nrog cov tshuab machining. Nws tuaj yeem muab faib ua txias machining thiab kub machining.
Txias machining feem ntau ua nyob rau hauv chav tsev kub thiab tsis ua rau muaj tshuaj lom neeg los yog lub cev hloov nyob rau hauv lub workpiece. Kev ua haujlwm ntawm qhov kub siab tshaj lossis qis dua chav tsev feem ntau ua rau muaj tshuaj lom neeg lossis lub cev hloov pauv hauv cov khoom ua haujlwm thiab hu ua thermal processing. Txias machining tuaj yeem muab faib ua kev txiav thiab siab machining raws li qhov sib txawv ntawm cov txheej txheem ua. Kev ua haujlwm kub feem ntau suav nrog kev kho cua sov, forging, casting thiab vuam.
Cov txheej txheem los ntawm precision machining yog raws li nram no.
1, lub geometry ntawm ib feem thiab kev sib nrig sib txoj hauj lwm raug rau micron los yog arc thib ob theem;
2, ciam teb ntawm ib feem los yog feature me me kam rau ua nyob rau hauv microns los yog tsawg dua;
3, ib feem ntawm qhov chaw microscopic unevenness (surface unevenness nruab nrab qhov siab qhov sib txawv) yog tsawg dua 0.1 microns;
4, qhov sib koom ua ke tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub zog haum;
5, qee qhov tseem tuaj yeem ua tau raws li cov neeg kho tshuab lossis lwm yam khoom siv lub cev ntawm qhov yuav tsum tau muaj, xws li lub zog torsional ntawm ntab gyroscope torsion bar, qhov tawv coefficient ntawm cov khoom hloov tau yooj yim, thiab lwm yam.
Precision machining yog ua tiav raws li kev tswj hwm ib puag ncig nruj me ntsis, siv cov cuab yeej siv tshuab precision thiab precision gauges thiab gauges. Machining raug mus txog thiab dhau ntawm 0.1 micron yog hu ua ultra-precision machining. Hauv kev lag luam aerospace, precision machining feem ntau yog siv los ua cov txheej txheem precision mechanical qhov chaw hauv cov cuab yeej siv dav hlau, xws li precision mating qhov chaw hauv hydraulic thiab pneumatic servo mechanisms, gyroscope thav ntawv thiab vaj tse, huab cua thiab kua ntab bearing sib dhos thiab ntab, thiab lwm yam. ntawm precision qhov chaw ntawm aircraft yog complex, me me nruj, siab precision yuav tsum, thiab feem ntau nyuaj rau tshuab cov ntaub ntawv yog loj.
