Nyob rau hauv lub ntiaj teb no ntawm precision metrology, lub hauv paus ntawm txhua qhov kev ntsuas qhov tseeb yog lub dav hlau siv tiag tiag. Rau cov neeg tswj xyuas kev tswj xyuas zoo thiab cov kws tsim hluav taws xob metrology, granite nto phaj tsis yog ib qho chaw ua haujlwm xwb; nws yog lub hauv paus ntawm kev ruaj ntseg zoo. Txawm li cas los xij, txawm tias qhov ruaj khov tshaj plaws Qib 00 nto phaj yuav tsum nruj calibration thiab tuav kom zoo los tuav nws txoj kev ncaj ncees lub sij hawm.
Ntawm Unparalleled Group, peb nkag siab tias qhov tseeb tsis yog ib qho - lub sijhawm tshwm sim - nws yog kev cog lus tas mus li. Cov lus qhia no qhia meej txog cov qauv kev tshaj lij rau kev txhim kho thiab ntsuas qib siab -cov phaj granite precision, ua kom koj cov cuab yeej ntsuas ntsuas ntsuas ua tau raws li qhov siab tshaj plaws.
Vim Li Cas Qib 00 Qhov Tseeb Qhov Tseeb
Qib 00 granite saum npoo daim hlau sawv cev rau qhov siab tshaj plaws ntawm qhov tseeb, feem ntau tshwj tseg rau cov qauv siv tswv yim hauv kev tswj xyuas ib puag ncig. Tsis zoo li Qib 0 lossis Qib 1 daim phiaj siv rau hauv pem teb khw, Qib 00 phaj yuav tsum tswj kom muaj kev sib haum xeeb hauv microns.
Lub superiority ntawm granite nyob rau hauv nws lub cev khoom:
Dimensional Stability: High- zoo granite (xws li cov nplua- cov ntaub ntawv nplej peb qhov chaw) muaj cov coefficient qis heev ntawm thermal expansion, ua rau nws tiv taus qhov kub thiab txias.
Durability: Nws tsis yog -sib nqus, xeb- pov thawj, thiab tshuaj tsis muaj zog.
Surface Hardness: Nrog Mohs hardness ntawm 6-7, nws tiv taus puas los ntawm cov cuab yeej ntsuas.
Txawm li cas los xij, cov khoom no tsuas yog siv tau yog tias lub phaj raug ntsuas thiab tswj kom raug.
Theem 1: Kev Txhim Kho & Kev Tswj Ib puag ncig
Ua ntej calibration yuav pib, ib puag ncig yuav tsum tau tswj. Qib 00 phaj yuav tsis ua raws li qhov tshwj xeeb hauv qhov chaw tsis hloov pauv.
Thermal Equilibrium: Lub phaj yuav tsum acclimate rau chav tsev kub (tus qauv yog 20℃/ 68℃F) tsawg kawg yog 24-48 teev ua ntej siv los yog calibration.
Vibration Isolation: Xyuas kom lub chaw txhawb nqa yog nruj thiab cais tawm ntawm kev co sab nraud. Granite muaj cov khoom damping zoo, tab sis qhov chaw mounting yuav tsum ruaj khov.
Cov ntsiab lus txhawb nqa: Kev txhawb nqa kom zoo yog qhov tseem ceeb los tiv thaiv lub pob zeb los ntawm sagging hauv qab nws qhov hnyav. Rau cov phaj plaub, qhov theoretical Airy ntsiab lus (0.554L) lossis Bessel cov ntsiab lus feem ntau yog siv los txhawb lub phaj, txo qis deflection.
Theem 2: Cov txheej txheem Calibration (Qib-los ntawm-Step)
Calibration ntawm granite nto phaj yuav xyuas qhov flatness ntawm qhov chaw ua hauj lwm tiv thaiv tus qauv paub. Thaum "Peb-Plate Method" (Whitworth method) yog cov txheej txheem ib txwm siv los tsim kom muaj qhov chaw tiaj tus, cov chaw kuaj ntsuas niaj hnub no feem ntau siv cov cuab yeej hluav taws xob qib lossis autocollimators rau kev txheeb xyuas.
Kauj Ruam 1: Kev Npaj Nto
Ua tib zoo ntxuav qhov chaw nrog lint -dawb ntaub thiab siab - cawv. Tshem tag nrho cov plua plav, roj, thiab burrs. Txawm tias ib qho microscopic particle tuaj yeem skew cov txiaj ntsig.
Kauj ruam 2: Tsim daim phiaj ntsuas
Faib qhov saum npoo rau hauv daim phiaj. Rau tus qauv 1000mm x 1000mm phaj, kab kab pheeb ces kaum thiab longitudinal yog qhov tseem ceeb. Qhov no tso cai rau kev tshawb pom ntawm "twist" lossis qhov sib txawv hauv zos.
Kauj Ruam 3: Sau cov ntaub ntawv
Siv cov qib hluav taws xob ntsuas hluav taws xob lossis ib qho pib -collimator:
Muab qhov ntsuas ntawm qhov chaw pib (zero).
Txav mus rau hauv cov kauj ruam uas tau hais tseg (piv txwv li, txhua 100mm) hla cov kab ntev, kab rov tav, thiab kab pheeb ces kaum.
Sau cov angular sib txawv ntawm txhua qhov chaw.
Kauj Ruam 4: Kev txheeb xyuas cov ntaub ntawv & Kev xam tsis paub tseeb
Cov ntaub ntawv khaws cia yog ua tiav los tsim ib daim ntawv qhia topographical ntawm qhov chaw. Lub flatness sib txawv yog xam raws li qhov sib txawv ntawm qhov siab tshaj plaws thiab qis tshaj cov ntsiab lus txheeb ze rau qhov zoo tagnrho siv dav hlau.
Rau qib 00 phaj, qhov kev ua siab ntev (TT) feem ntau suav nrog cov qauv:
T=2 ×(1+D25) µmT=2 ×(1+25D) µm
(Qhov twg DD yog kab pheeb ces kaum ntev ntawm qhov chaw ua haujlwm hauv ntiv tes, lossis raws li cov qauv tshwj xeeb xws li GB / T 20428 lossis DIN 876).
Yog hais tias qhov ntsuas qhov sib txawv poob rau hauv qhov kam rau siab rau Qib 00, lub phaj tau ntawv pov thawj. Yog tsis yog, nws yuav xav tau resurfacing lossis downgrading rau Qib 0.
Theem 3: Kev Kho Kom Zoo Rau Lub Neej Ntev
Txhawm rau kom ntseeg tau tias koj cov peev nyiaj tseem nyob hauv qhov ua siab ntev:
Tig Kev Siv: Tsis txhob siv tib qhov chaw ntawm lub phaj ntau zaus. Txav koj qhov teeb tsa kom faib khoom sib npaug.
Npog nws: Ib txwm siv cov ntoo los yog yas npog thaum lub phaj tsis siv los tiv thaiv plua plav thiab kev puas tsuaj.
Tsis txhob cuam tshuam: Granite yog tawv tab sis nkig. Ib qho kev cuam tshuam ntse tuaj yeem ua rau lub hauv paus nti lossis "zais" uas cuam tshuam rau tag nrho lub dav hlau.
Koom tes nrog Unparalleled Group
Kev tuav qib 00 qhov tseeb tsis yog hais txog pob zeb xwb; nws yog hais txog kev txawj ntse tom qab lub calibration. Ntawm Unparalleled Group, peb muab tsis tau tsuas yog hwm granite saum npoo daim hlau tab sis kuj muaj kev txhawb nqa thiab calibration cov kev pabcuam uas yuav tsum tau ua kom koj chav kuaj ua raws li cov qauv thoob ntiaj teb.
Txawm hais tias koj xav tau ib qho kev cai -qhov loj ntawm granite los yog tag nrho cov kev ntsuas ntsuas, cia siab rau cov kws tshaj lij uas nkag siab txog kev tshawb fawb ntawm flatness.
