Nyob rau hauv lub ntiaj teb no ntawm precision manufacturing, "flat" yog ib tug txheeb ze lub sij hawm. Rau lub rooj sib tham rooj sib tham, qhov sib txawv ntawm ib feem kaum ntawm ib millimeter yuav tsis pom. Txawm li cas los xij, hauv chav ntsuas ntsuas lossis chav tsev semiconductor, qhov sib txawv ntawm qhov ua siab ntev ntawm ± 0.01mm thiab ± 0.005mm tsis yog ib qho teeb meem ntawm cov lej xwb- nws sawv cev rau kev hloov pauv hauv kev ntsuas ntsuas. Nkag siab txog granite nto phaj flatness kam rau ua tau piav qhia yog qhov tseem ceeb rau txhua tus kws ua haujlwm ua haujlwm nrog xaiv lub hauv paus rau siab - daws teeb meem Kev Sib Koom Tes Ntsuas Tshuab (CMMs) lossis laser interferometry teeb tsa.
Rau qhov muag tsis pom kev, ob daim phiaj zoo tib yam. Tab sis hauv qab ntawm qhov chaw, micro-topography ntawm lub pob zeb hais txog "kev ntsuas qab nthab" ntawm koj tag nrho cov txheej txheem tswj kom zoo. Cia peb tshawb nrhiav qhov tseeb ntawm cov kev zam no thiab seb lawv cuam tshuam li cas rau koj cov kab hauv qab.
Txhais lub hnab ntawv: Cov lej no txhais li cas?
Thaum peb tham txog granite nto phaj flatness kam rau ua tau piav qhia, peb tab tom xa mus rau qhov kev ncua deb ntawm ob lub theoretical parallel dav hlau uas muaj tag nrho cov ncov thiab hav ntawm lub phaj saum npoo.
± 0.01mm (10 Microns): Qhov no feem ntau ua raws li DIN 876 Qib 0 lossis ISO 8512 Qib A. Nws yog tus qauv rau siab -cov chaw soj ntsuam zoo.
± 0.005mm (5 Microns): Qhov no thawb mus rau hauv lub realm ntawm Qib 000 los yog "Lab Qib." Nws yuav tsum tau txhais tes ntau dua -lapping lub sijhawm thiab kev tswj hwm ib puag ncig zoo dua thaum lub sijhawm tsim khoom.
Cov nyhuv Multiplier: Yuav ua li cas Flatness cuam tshuam Volumetric yuam kev
Yog vim li cas engineers obsess tshaj ob peb microns no yog vim "lever effect." Lub phaj nto tsis tshua siv los xyuas qhov flatness ntawm ib feem me me; Nws yog siv los ua cov ntaub ntawv rau qhov ntsuas qhov siab lossis CMM caj npab.
Yog tias lub ntsuas qhov siab 500 hli tau txav mus hla lub phaj nrog ± 0.01mm flatness sib txawv, qhov microscopic "slope" hauv granite yog qhov loj dua li qhov ntsuas tau nce mus. A 10-micron yuam kev ntawm lub hauv paus tuaj yeem txhais ua qhov yuam kev loj dua ntawm qhov ntsuas qhov ntsuas. Los ntawm kev zawm lub tiaj tiaj rau ± 0.005mm, koj ua tau zoo ib nrab ntawm qhov kev ua yuam kev ntawm txhua qhov kev ntsuas hauv qhov chaw ua haujlwm. Rau aerospace Cheebtsam los yog kev kho mob implants qhov kam rau ua yog ntsuas nyob rau hauv ib tug lej microns, lub ± 0.01mm phaj tej zaum yuav tau "siv" 50% ntawm koj tag nrho cov nyiaj tso cai yuam kev.
Thermal Stability thiab "ua pa" ntawm pob zeb
Lwm qhov tseem ceeb ntawm granite nto phaj flatness kam rau ua tau piav qhia yog yuav ua li cas cov kev kam rau ua nyob rau hauv qhov tiag - ntiaj teb no. Lub phaj ntawv pov thawj rau ± 0.005mm yog qhov tseeb ntawm cov pob zeb ruaj khov dua. Ua kom tiav qib ntawm qhov tseeb no yuav tsum tau siv ultra-siab- ntom granite, xws li Jinan Black, uas muaj qis coefficient ntawm thermal expansion.
Lub phaj nrog ± 0.01mm kam rau ua yuav ua rau muaj kev cuam tshuam ntau dua rau "ntxuav" yog tias chav tsev kub hloov los ntawm 1℃lossis 2 degree. Nyob rau hauv sib piv, ib tug ± 0.005mm phaj los ntawm UNPARALLELED Group yog engineered nrog lub thermal inertia tsim nyog los tuav nws profile. Qhov no txhais tau tias tsawg dua recalibrations thiab muaj kev ntseeg siab dua rau koj cov ntaub ntawv thaum lub sij hawm ntev - hloov ntau lawm cycles.
Hnav Resistance thiab lub neej ntev ntawm Precision
Flatness tsis yog lub xeev ruaj khov; nws yog ib qho khoom siv tau. Txhua lub sij hawm ib feem yog zawv zawg hla cov granite, cov khoom siv microscopic raug tshem tawm. Lub phaj ua rau ± 0.005mm specification feem ntau muaj cov tawv tawv dua thiab cov qauv zoo dua.
Thaum thawj zaug peev hauv Qib 000 phaj siab dua, nws "lub neej ua haujlwm" feem ntau ntev dua. Vim tias nws pib ntawm qib siab dua, nws yuav siv sij hawm ntev dua rau kev hnav kom degrade nto mus rau qhov chaw uas nws ua tsis tiav ISO 17025 calibration. Rau siab-cov chaw soj ntsuam ntim ntim, tus nqi- ib- xyoo ntawm ± 0.005mm phaj feem ntau qis dua qhov pheej yig dua, softer ± 0.01mm lwm txoj.
Xaus: Sib piv lub Foundation rau Lub Hom Phiaj
Yog li, koj xaiv li cas? Yog tias koj txoj haujlwm suav nrog kev tshuaj xyuas txhua yam, ± 0.01mm (Qib 0) muab cov txiaj ntsig zoo thiab kev ntseeg siab. Txawm li cas los xij, yog tias koj tab tom sib koom ua ke huab cua- cov theem kabmob, ua haujlwm CMM calibration, lossis kev tsim khoom semiconductor-qib optics, qhov ± 0.005mm (Qib 000) tsis yog khoom kim heev- nws yog qhov tsim nyog.
Ntawm UNPARALLELED Group, peb tsis ntseeg tias "ze txaus." Txhua lub phaj peb tsim yog ib qho pov thawj rau kev nrhiav qhov tseeb xoom. Los ntawm kev nkag siab txog granite nto phaj flatness kam rau ua tau piav qhia, koj tuaj yeem ua qhov kev txiav txim siab uas ua rau qhov tseeb ntawm koj cov khoom thiab lub koob npe nrov ntawm koj lub npe.
