Weihua thev naus laus zis co., LTD yog lub tuam txhab ua haujlwm precision CNC machining tuam txhab nrog ntau tshaj 10 xyoo ntawm kev thev naus laus zis tshuab, muab cov lag luam suav nrog: precision CNC xa, CNC precision qhov chaw ua, aluminium alloy ua, cov ntu ua CNC, cov txheej txheem tsis-txheem CNC ua thiab ntau yam ntawm cov precision CNC machining; Peb tau ntsib cov kws tshaj lij thiab cov kws tshaj lij thiab cov kws tshaj lij kev paub, zoo siab txais tos sab laj.
Dab tsi yog hom kev faib tawm ntawm ultra-precision CNC machining?
Ib qho, Ultra-precision CNC machining
Muaj feem ntau ultra-precision tig, daim iav sib tsoo thiab kev sib tsoo.Hauv lub tshuab dhos ultra-precision tom qab kev sib tsoo zoo ntawm tib lub pob zeb diamond tig lub cuab tam rau micro tig, txiav tuab ntawm tsuas yog li 1 micron, feem ntau siv los ua cov khoom siv tsis muaj hlau ua cov hlau. kheej kheej, aspheric nto thiab nto ntawm qhov chaw, xws li high-precision, du nto ntawm qhov chaw.
Piv txwv, cov tshuaj pleev xim aspheric nrog txoj kab uas hla 800 hli siv nyob rau hauv cov khoom siv fusion nuclear muaj qhov tseeb tshaj plaws mus txog 0.1 micron, thiab qhov saum npoo tawv yog Rz0.05 micron.
Ob, ultra-precision CNC precision xa cov khoom ua tshwj xeeb
Machining precision rau nanometer, thiab nws thiaj li mus rau atomic chav tsev (atomic lattice nrug yog 0.1 ~ 0.2 nm) raws li lub hom phiaj, machining txoj kev tsis tuaj yeem ua, xav tau cov txheej txheem tshwj xeeb, xws li daim ntawv thov ntawm lub zog tshuaj, electrochemistry zog, cua sov lossis hluav taws xob thiab yog li ntawd, ua kom cov zog no dhau ntawm qhov kev siv hluav taws xob ntawm nruab nrab ntawm atoms, yog li tshem qhov ntu ntawm qhov nruab nrab ntawm qhov chaw ntawm lub ntsej muag workpiece adhesion, khi thiab lattice deformation, thiaj li ua tiav lub hom phiaj ntawm ultra precision machining.
Cov txheej txheem no suav nrog kev siv tshuab-tshuaj polishing, ion sputtering thiab ion implantation, electron nqaj aeration, laser beam ua, hlau evaporation thiab molecular beam epitaxy.
Cov hau kev no tau cim los ntawm kev tswj tau zoo ntau dhau ntawm qhov nyiaj ntawm txheej txheej khoom tshem tawm lossis ntxiv ntxiv.Txawm li cas los, kom tau txais lub tshuab ultra-precision machining precision, nws tseem nyob ntawm qhov ua tau zoo ntawm cov cuab yeej ua tiav thiab cov tswj kev npliag, thiab siv lub ultra-precision. npog ntsej muag li qhov intermediary.
Piv txwv li, cov phaj ua vlsi yog siv cov hluav taws xob hluav taws xob kom nthuav tawm cov photoresist rau ntawm daim npog (saib photolithography), yog li ntawd qhov atoms ntawm photoresist yog ncaj qha polymerized (lossis decomposed) nyob rau hauv qhov cuam tshuam ntawm cov khoom siv hluav taws xob, thiab tom qab ntawd ces ib feem ntawm lub polymer lossis tsis polymerized yog yaj los ntawm kev tsim tawm los ua lub npog ntsej muag.Electron beam raug phaj ua kev ua yuav tsum muaj kev cuam tshuam loj heev CNC CNC machining cov khoom siv nrog qhov tseeb qhov tseeb txog ± 0.01 micron.
