Nyob rau hauv qhov tsis tshua muaj huab cua ntawm ultra- precision engineering thiab kev ntsuas qib siab, granite nto phaj tsis yog ib qho chaw ua haujlwm xwb; nws yog lub hauv paus, kiag li siv dav hlau tiv thaiv tag nrho lwm yam kev ntsuas raug txiav txim. Thaum cov engineers qhia meej meej granite platform, lawv tab tom thov kom lav qhov tseeb geometric, thiab cov qauv siab tshaj plaws muaj rau cov kev ntsuas dav dav feem ntau raug xaiv raws li Qib 00 (los yog Qib AA hauv qee qhov kev qhia qub).
Tab sis dab tsi raws nraim qib 00 flatness txhais rau hauv cov ntsiab lus tangible, ntsuas tau? Qhov kev tso cai yuam kev yog dab tsi, thiab vim li cas qhov kev ua tau zoo no tseem ceeb rau kev txhawb nqa cov cuab yeej xws li cov khoom siv hluav taws xob semiconductor, siab - daws teeb meem CMMs, thiab granite pa bearings? Ntawm UNPARALLELED Group, tus kws tshaj lij kev tsim khoom tau cog lus rau cov qauv thoob ntiaj teb siab tshaj plaws, peb ntseeg tias kev nkag siab txog cov kev zam no yog qhov tseem ceeb rau txhua tus neeg siv khoom nrhiav qhov tseeb, ntiaj teb -chav kawm precision.
Defining Flatness: Lub Bedrock ntawm Metrology
Flatness yog geometric kam rau ua uas tswj ntau npaum li cas ntawm qhov chaw tuaj yeem sib txawv ntawm lub dav hlau zoo meej. Nws yog ib qho tseem ceeb tshaj specification rau agranite nto phaj. Qhov kev sib txawv no feem ntau ntsuas raws li tag nrho cov ntsug nrug ntawm qhov siab tshaj plaws thiab qhov qis tshaj plaws ntawm tag nrho cov chaw ua haujlwm.
Qib kev faib cov tshuab tau tsim thoob ntiaj teb los ntsuas cov qib ntawm kev ua tiav tau zoo. Txawm hais tias muaj ntau yam qauv (xws li Tsoom Fwv Teb Chaws Asmeskas Kev Qhia Tshwj Xeeb GGG-P-463C, Japanese JIS B 7510, German DIN 876, thiab European EN 10002), lawv txhua tus sib koom lub hom phiaj: txhawm rau txheeb xyuas cov phiaj xwm raws li lawv qhov kev sib txawv ntawm tag nrho cov kev sib txawv ntawm qhov zoo.
Tus Qauv Bearer: Qib 00 (Lab Qib)
Qib 00 qhov kev xaiv sawv cev rau qib siab tshaj plaws uas npaj rau kev siv sab nraud ntawm qhov kev tshawb fawb tshwj xeeb tshaj plaws. Nws feem ntau hu ua "Master" lossis "laboratory Grade."
Los teb cov lus nug tseem ceeb: Dab tsi yog qhov kev ua yuam kev flatness rau Qib 00 precision granite nto phaj?
Qhov kam rau ua yog nruj nruj thiab ncaj qha proportional rau qhov ntev ntawm lub phaj kab pheeb ces kaum. Thaum cov qauv tshwj xeeb sib txawv me ntsis, qhov raug lees txais kev zam rau aQib 00 nto phajRaws li cov qauv siv dav dav DIN 876/I/II tuaj yeem sau tau raws li hauv qab no (raws li tag nrho ntsuas kab pheeb ces kaum ntev L hauv mm):
Qib 00 Tag Nrho Flatness kam rau ua ≈ ± (0.001 + 0.001 Lm) mm
Qhov twg Lm yog kab pheeb ces kaum ntev hauv meters.
Rau kev ua piv txwv, cia peb tshuaj xyuas qhov kam rau ua rau cov phaj loj loj uas siv cov qauv nruj DIN 876:
| Nominal Loj (mm) | Diagonal Ntev L (m) | Qib 00 Total Flatness kam rau ua (μm) | Qib 00 Total Flatness kam rau ua (mm) |
| 630 × 400 | ≈ 0.75 | 1.75 μm | 0.00175 hli |
| 1000 × 630 | ≈ 1.18 | 2.18 μm | 0.00218 hli |
| 2000 × 1000 | ≈ 2.24 | 3.24 μm | 0.00324 hli |
| 4000 × 1600 | ≈ 4.30 | 5.30 μm | 0.00530 hli |
Qhov no txhais tau hais tias Qib 00 phaj ntsuas qhov ntev 2 meters muaj tag nrho cov kev cai flatness yuam kev ntawm tsuas yog 3 micrometers (μm). Qhov no yog ib feem ntawm qhov dav ntawm tib neeg cov plaub hau thiab yog qib ntawm geometric zoo meej uas yuav tsum tau ua rau cov kev ntsuas siab tshaj plaws thiab lub tsev tshuab.
Yog vim li cas thiaj li Flatness siab heev tsis yog -Ngotiable
Qib 00 kam rau ua tsis yog ib qho kev qhia tshwj xeeb; nws yog qhov yuav tsum tau ua ua ntej rau cov ntawv thov uas yuav tsum tau muaj qhov sub-micron positioning thiab ntsuas qhov tseeb. Tag nrho flatness yuam kev ncaj qha mus rau qhov ntsuas tsis paub tseeb ntawm txhua lub cuab yeej muab tso rau nws.
Laser Interferometry thiab CMMs: Siab-kawg tswj kev ntsuas tshuab thiab ntau-axis ntsuas tshuab, uas tso siab rau laser- taw qhia qhov chaw (xws li cov ntsuas nrog British Reinshaw laser interferometers peb ua haujlwm), xav tau lub dav hlau zoo kawg nkaus, ruaj khov siv dav hlau. Txhua qhov sib txawv hauv lub hauv paus txhais ncaj qha rau hauv qhov chaw yuam kev, cuam tshuam qhov tseeb ntawm tag nrho lub tshuab. A Qib 00 lub hauv paus txo qhov kev ua yuam kev hauv paus.
Cua Bearing Performance: Kev siv hauv cov khoom siv semiconductor thiab ultra-siab-ceev XY Tables feem ntau siv granite pa bearings. Qhov kev ua tau zoo ntawm cov tshuab tsis muaj kev sib txhuam no yog nyob ntawm kev tswj hwm qhov sib xws, micron - theem huab cua sib txawv. Lub tiaj tiaj tiaj ntawm Qib 00 phaj yog qhov tseem ceeb los tiv thaiv huab cua tawm, ua kom lub siab tsis sib xws, thiab lav qhov ruaj khov ntawm qhov xav tau rau kev xav tau kev ua haujlwm xws li microlithography lossis qib siab optics tso.
Gauge Calibration: Qib 00 daim hlau yog tshwj xeeb rau calibrating siab -cov cuab yeej ntsuas qhov tseeb xws li qib hluav taws xob, autocollimators, thiab siab - kev daws teeb meem dial ntsuas (xws li German Mahr ntsuas peb siv, raug rau 0.5 μm). Yog tias daim ntawv qhia nws tus kheej tsis raug rau qib siab no, qhov ntsuas ntsuas ntawm qhov ntsuas yuav raug ua txhaum.
Ua tiav Qib 00: Qhov Zoo Tshaj Tsis Pom Zoo
Kev tsim khoom ntawm qib 00 phaj tiag tiag yuav tsum muaj kev sib koom ua ke ntawm cov khoom siv zoo tshaj plaws, kev txiav -ntug infrastructure, thiab kev hloov tsis tau rau tib neeg kev txawj ntse- cov ncej heev uas UNPARALLELED Group tsim.
Cov Khoom Siv Kev Ncaj Ncees: Peb pib nrog UNPARALLELED® Dub Granite, uas khav theeb kev lag luam -ua qhov ntom ntom ntawm ≈ 3100 kg / m³ thiab ze rau - xoom dej nqus tus nqi. Cov khoom siv ruaj khov no tsis yog- sib tham tau rau Qib 00, vim nws ua kom lub phaj tsis tshua muaj kev cuam tshuam rau thermal expansion thiab ntev -lub sij hawm nyob rau hauv kev ntxhov siab, tuav nws flatness ntau xyoo lawm.
Tswj Ib puag ncig: Qib 00 daim hlau tsis tuaj yeem ntsuas tau hauv cov xwm txheej tsis ruaj khov. Peb 10,000 m² qhov chaw ua haujlwm kub thiab av noo tas li, ua tiav nrog 1000 hli tuab, kev co- cov plag tsev sib cais, tsim ib puag ncig uas cuam tshuam rau sab nraud, tso cai rau qhov tseeb, ntsuas qhov ncaj.
Art of Hand Lapping: Thaum peb siv cov cuab yeej sib tsoo siab heev (xws li lub peev xwm 6000 hli Taiwan Nante grinders), ua tiav qib 00 kawg yog ib qho kev kos duab ua los ntawm peb cov kws txawj ua haujlwm lapping. Cov kws tshaj lij no, muaj ntau tshaj li 30 xyoo ntawm kev paub dhau los, muaj qhov tactile rhiab heev rau "xav" saum npoo mus rau qib nanometer, ua qhov kev hloov kho zaum kawg uas yuav tsum tau thawb qhov kev ua yuam kev flatness mus rau ib qho -micrometer ntau yam. Raws li peb tau hais khov kho, "Lub lag luam precision tsis tuaj yeem xav tau dhau lawm."
Traceability thiab Certification: Cov pov thawj ntawm kev ua tau zoo
Rau qhov precision granite platform kom ntseeg tau tias Qib 00, nws cov ntawv pov thawj yuav tsum yog qhov tseeb. Txhua Qib 00 cov khoom lag luam los ntawm UNPARALLELED Group yog nruj me ntsis ntsuas siv cov khoom siv ntsuas ntsuas thawj zaug thiab suav nrog daim ntawv pov thawj ntawm kev ntsuas ntsuas rov qab mus rau lub koom haum metrology hauv tebchaws. Qhov kev ua raws li kev txheeb xyuas qhov tseeb yog qhov laj thawj tseem ceeb vim li cas peb tsuas yog cov chaw tsim khoom hauv peb cov haujlwm los tuav ib txhij ISO 9001, ISO 45001, thiab ISO 14001 ntawv pov thawj.
Hauv kev xaus, thaum koj nqis peev rau qib 00 granite nto phaj los ntawm UNPARALLELED Group, koj tsis yog tsuas yog yuav ib pob zeb; koj tau txais ib daim ntawv pov thawj siv dav hlau qhov twg qhov siab tshaj plaws tag nrho qhov yuam kev raug txwv rau ob peb micrometers thoob plaws tag nrho saum npoo. Qhov tshwj xeeb ntawm qhov zoo tshaj plaws ntawm geometric perfection no yog qhov tseem ceeb, tus khub ntsiag to uas ua rau cov tiam tom ntej ntawm ultra- precision manufacturing thiab ntsuas thoob ntiaj teb.
