Thaum Lub Xya Hli 7, 2026, National Institute of Metrology (NIM), Tuam Tshoj, tshaj tawm txoj haujlwm ua tiav ntawm lub teb chaws thawj qhov siab -precision roundness thawj cov khoom siv.
Kev ntsuas qhov tsis paub meej rau kev sib tw tau raug txo los ntawm 20 nanometers mus rau 6 nanometers, nqa cov peev xwm ntsuas mus rau qib siab thoob ntiaj teb.
Nws yuav zoo li ib daim xov xwm tshwj xeeb, tab sis nws qhov tseem ceeb tshaj qhov tshwm sim ntawm qhov chaw.
I. Dab tsi yog roundness, thiab vim li cas nws thiaj tseem ceeb?
Cia peb pib nrog lub tswv yim: roundness yog ib qho tseem ceeb, qhov tseem ceeb tsis nyob rau hauv geometric dimensioning thiab tolerancing (GD&T) system.
Txhawm rau muab nws yooj yim: tsuas yog yuav ua li cas "round" ib feem ncaj qha txiav txim siab seb nws puas siv tau thiab nws ua tau zoo npaum li cas.
Ncaj, flatness, roundness, cylindricity ... koj puas paub cov geometric tolerances? - Zhihu
Yog hais tias lub precision spindle tsis zoo tag nrho, qhov tseeb machining ntawm lub tshuab cuab yeej raug kev txom nyem. Yog tias lub lens optical tsis yog puag ncig, cov duab tshwm sim yuav pom qhov muag plooj. Yog hais tias ib tug semiconductor wafer tsis puag ncig, nti tawm tus nqi yuav poob.
Roundness ntsuas qhov tseeb yog txuas ncaj qha rau kev ua tau zoo thiab kev sib dhos zoo ntawm cov khoom siv siab -kawg tsim, xws li precision spindles, advanced optical Cheebtsam, thiab semiconductor chips.
Yav dhau los, Tuam Tshoj muaj lub teb chaws tus qauv ntsuas rau kev tiaj tus, tab sis tsis muaj lub teb chaws -qib qhov chaw ntawm traceability rau roundness qhov tseem ceeb.
Qhov no txhais li cas? Nws txhais tau hais tias rau roundness -cov khoom lag luam uas tsim los ntawm cov tuam txhab hauv tsev, tsis muaj "tus qauv qauv hauv tebchaws" rau kev sib piv. Txhawm rau calibrate cov cuab yeej lossis txheeb xyuas qhov tseeb, cov tuam txhab yuav tsum tso siab rau cov tsev kawm txawv teb chaws.
Qhov no yog ib qho piv txwv classic ntawm qhov teeb meem "choke-point"-ib qho tseem ceeb ntawm kev vam khom rau txawv teb chaws technology.
II. Qhov kev vam meej no ua tiav li cas?
Cov cuab yeej no tau tsim los ntawm National Institute of Metrology, Suav. Technically, nws daws tau peb qhov kev sib tw thoob ntiaj teb:
Siab -kev ntsuas qhov tseeb roundness, spindle yuam kev sib cais, thiab filtering sib xws tswj.
Tshwj xeeb tshaj yog, cov cuab yeej tau qhia txog tus qauv kev ntsuas kev hloov pauv tshiab raws li qhov siab - qhov tseeb roundness lim thiab siv cov ntaub ntawv dav dav, daws qhov teeb meem ntawm kev tsim kho profile kom ruaj khov tom qab kev sib cais hemisphere.

Nyob rau tib lub sij hawm, ib tug tshiab tsim, proprietary yuam kev sib cais tshuab ho suppressed spindle rotation yuam kev.
Qhov no txo qis kev ntsuas qhov tsis paub meej ntawm 20 nanometers rau 6 nanometers.
20 nanometers txhais tau li cas? Txoj kab uas hla ntawm tib neeg cov plaub hau yog kwv yees li 80,000 nanometers. Ntawm 6 nanometers, qhov ntsuas precision ncav cuag atomic scale. [Duab]
Qhov no qhia tau hais tias kuv lub teb chaws tau ua tiav kev tswj hwm ywj pheej ntawm cov thev naus laus zis tseem ceeb uas xav tau rau siab - qhov tseeb roundness ntsuas.
III. Cov kev lag luam twg yuav tau txais txiaj ntsig ncaj qha?
Cov txheej txheem no yuav muab kev ntseeg siab, siab -kev ua kom pom tseeb metrological traceability txhawb rau kev lag luam tawm tswv yim xws li aerospace, siab -kawg tshuab cuab yeej, qib siab optics, thiab semiconductor manufacturing.
Cia peb saib lawv ib leeg.
Aerospace: Cheebtsam xws li aircraft cav rotors, bearings, thiab turbine disks xav tau siab heev roundness precision. Txawm tias qhov sib txawv me ntsis hauv kev sib tw tuaj yeem ua rau muaj teeb meem loj thaum lub sijhawm ua haujlwm siab -. Kev ntsuas thev naus laus zis muaj peev xwm ntawm 0.3-micrometer precision tuaj yeem txhim kho tus nqi dhau thiab kev sib dhos zoo sib xws ntawm cov khoom siv dav hlau. Nrog rau kev tsim lub teb chaws-theem roundness benchmark, aerospace manufacturing tam sim no muaj tus qauv meej rau kev tswj kom zoo.
High-kawg tshuab cuab yeej: Kev sib hloov qhov tseeb ntawm lub tshuab cuab tam spindle ncaj qha txiav txim siab machining precision. Yog hais tias lub spindle tsis muaj roundness, lub machined qhov chaw yuav tsis muaj roundness. Kev ua tiav ntawm qhov kev ntsuas qhov ntsuas qhov ntsuas no muab cov qauv kev ntsuas qhov tseeb rau lub tshuab cuab yeej kev lag luam.
Advanced optics: Lub roundness ntawm optical lo ntsiab muag thiab tsom iav ncaj qha cuam tshuam rau cov duab zoo. Thaum nanometer- theem precision yog yuav tsum tau, roundness ntsuas yog ib kauj ruam indispensable.
Kev tsim khoom semiconductor: Lub roundness thiab flatness ntawm wafers ncaj qha cuam tshuam lithography precision thiab nti tawm los. Cov khoom siv semiconductor feem ntau muaj cov thicknesses ntawm nanometer nplai. Kev ntsuas muaj peev xwm ntawm 6 nanometers hits "qhov chaw qab zib" rau qhov kev xav tau tseem ceeb tshaj plaws hauv kev tsim khoom semiconductor.
Ua txhaum txawv teb chaws monopolies! kuv lub teb chaws ua tiav nws thawj qhov siab -precision roundness benchmark system, pab aerospace thiab semiconductor manufacturing.
IV. Qhov no tsis yog ib qho kev sib cais, tab sis yog lub teeb liab ntawm kev nthuav dav.
Qhov tseem ceeb ntawm qhov kev ua tiav no tau pom meej dua thaum pom hauv cov ntsiab lus dav dua.
Los ntawm 2025, kev lag luam loj rau cov cuab yeej precision hauv Suav teb tau mus txog kwv yees li 960 billion yuan. Kev lag luam thoob ntiaj teb rau cov cuab yeej ntsuas kev lag luam tau mus txog $ 5.76 nphom hauv 2025 thiab tau kwv yees tias yuav loj hlob mus txog $ 9.557 billion los ntawm 2032.
Qhov no yog kev lag luam muaj nqis ntau pua lab-thiab nws loj hlob sai heev.

Nyob rau tib lub sijhawm, tus qauv ntawm kev hloov pauv hauv tsev tau nrawm dua. Nyob rau ntawm 2026 CCMT tshuab cuab yeej exhibition, lub domestic precision ntsuas sector tau pom ib tug meej qauv: txav los ntawm tsuas yog "functional" mus rau "siab-kev ua tau zoo," thiab hloov los ntawm "piecemeal hloov" mus rau "systemic autonomy."
Txij li thaum pib ntawm 14th Tsib-Xyoo Plan, kuv lub teb chaws tau tsim 34 tshiab lub teb chaws metrology benchmarks -ib 89% xyoo- ntawm - xyoo nce - nrog ntau mus txog qib siab thoob ntiaj teb cov qauv. Raws li * Master Plan for the Metrology Foundation Strengthening Project*, kuv lub teb chaws lub hom phiaj kom ua tiav kev tswj hwm tus kheej ntawm ntau tshaj 60% ntawm nws lub teb chaws metrology benchmarks los ntawm 2030.
Kev ua tiav ntawm qhov ntsuas ntsuas qhov ntsuas ntsuas ntsuas tsuas yog ib qho tseem ceeb hauv qhov kev nthuav dav no.
V. Kev Hloov Kho Kev Lag Luam tseem tab tom pib
Kev ntsuas Precision ua haujlwm raws li "qhov muag" ntawm kev tsim khoom lag luam. Yog lub qhov muag pom tsis tau meej, txhais tes tsis tuaj yeem ua haujlwm nrog qhov tseeb.
Yav dhau los, domestic high -end manufacturers feem ntau tso siab rau txawv teb chaws metrology qauv thiab calibration cov kev pab cuam rau roundness - hais txog kev ntsuam xyuas thiab calibration. Qhov no tsis yog tsuas yog kim thiab lub sijhawm-siv tab sis kuj tso lawv nyob ntawm lwm tus.
* Muaj ntau ntau hom roundness tsis - Zhihu *
Tam sim no, nrog rau kev tsim lub teb chaws roundness benchmark, tag nrho cov kab ke ntawm metrological traceability tau pom nws "hauv paus."
Qhov no txhais li cas?
Cov tuam txhab tsim khoom hauv tsev ntawm cov ntsuas ntsuas ntsuas ntsuas tam sim no muaj lub teb chaws tus qauv tiv thaiv qhov twg los ntsuas lawv cov khoom. Yav dhau los, lawv yuav thov tau siab precision tab sis tsis muaj pov thawj ntawm lub teb chaws - theem traceability; tam sim no, lawv tuaj yeem muab tau.
High-cov tuam txhab kawg tam sim no muaj cov ntaub ntawv pov thawj hauv tsev rau kev txheeb xyuas cov khoom thiab kev tswj xyuas kom zoo, tshem tawm qhov xav tau xa cov qauv mus rau txawv teb chaws rau calibration.
Lub hauv paus tau muab tso rau kev sib koom ua ke ntawm cov qib precision thoob plaws tag nrho cov saw hlau.
Qhov no sawv cev rau kev txav mus rau kev hloov pauv hauv tsev uas pib ntawm "hauv paus."
VI. Qee qhov kev xav
Precision metrology tsis tshua nyiam rau pej xeem mloog; nws tsis bask nyob rau hauv lub tsom teeb zoo li chips los yog lithography tshuab.
Txawm li cas los, nws tsim lub hauv paus ntawm tag nrho cov precision manufacturing.
Yog tsis muaj qhov tseeb roundness benchmark, precision spindles tsis tuaj yeem raug tsim kom raug. Yog hais tias spindles tsis precision, tshuab cuab yeej raug txom nyem; yog tias cov cuab yeej siv tshuab raug raug kev txom nyem, tsis muaj dab tsi zoo tuaj yeem tsim tau.
Nws yog cov saw tsis pom, tab sis txhua qhov txuas tuav tus yuam sij rau kev lag luam qhov tseem ceeb.
Kev ua tiav ntawm qhov ntsuas ntsuas qhov ntsuas ntsuas ntsuas qhov sib txawv tseem ceeb hauv lub teb chaws geometric metrology system. Thaum nws tsis ncaj qha tsim cov khoom siv, nws muab kev sib koom ua ke "kev sib koom ua ke" rau qhov tseeb ntawm txhua yam khoom.
Los ntawm 20 nanometers mus rau 6 nanometers -cov zauv txawv yuav zoo li me me. Txawm li cas los xij, ntawm qhov ntsuas no, txhua nanometer ntawm kev nce qib tsuas yog ua tiav los ntawm xyoo ntawm kev ua haujlwm thev naus laus zis.
Qhov tseem ceeb ntawm cov txheej txheem no tsis yog nyob rau hauv yuav ua li cas "zoo siab" cov cuab yeej nws tus kheej yog, tab sis nyob rau hauv qhov tseeb hais tias nws muab ib tug ntau txhim khu kev qha lub hauv paus ntawm precision rau Tuam Tshoj lub siab - kawg manufacturing sector.
Lub ntsiab lus:
Hauv kev ntsuas qhov tseeb, koj xav li cas yog qhov tseem ceeb tom ntej "chokepoint" uas yuav tsum tau kov yeej? Puas yog qhov kev xav tau siab dua - cov cuab yeej ntsuas qhov tseeb, lossis qhov xav tau kom muaj zog ntau dua ntawm kev ntsuas ntsuas ntsuas?
