Cov phaj granite yog cov cuab yeej tseem ceeb hauv kev ntsuas thiab tsim khoom kom raug, tab sis tsis yog txhua daim phaj yog tsim sib npaug. Qib A thiab Qib B granite phaj sib txawv ntau heev ntawm qhov tseeb, qhov tiav ntawm qhov chaw, cov xwm txheej siv, thiab tus nqi. Kev nkag siab txog cov kev sib txawv no pab cov lag luam xaiv qhov kev xaiv tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb.
Kev Ua Siab Ntev: Lub Hauv Paus ntawm Kev Ua Kom Tseeb
Kev kam rau siab ntawm qhov tiaj tiaj yog qhov sib txawv tseem ceeb ntawm ob qib. Raws li American Society of Mechanical Engineers (ASME) B89.3.7 tus qauv, Qib A phaj muab qhov tseeb dua. Piv txwv li, ntawm 12 "x 12" phaj, Qib A feem ntau muaj qhov kam rau siab ntawm ± 0.00008 ntiv tes, ua kom muaj qhov tiaj tiaj zoo meej. Qhov sib piv, Qib B phaj muaj qhov kam rau siab dua, nyob ib puag ncig ± 0.00012 ntiv tes rau tib qhov loj me. Qhov sib txawv no ua rau Qib A zoo tagnrho rau cov ntawv thov uas xav tau qhov tseeb heev, xws li kev ntsuas cov cuab yeej ntsuas siab, thaum Qib B txaus rau cov haujlwm tshuaj xyuas dav dav hauv cov chaw ua haujlwm.
Qhov Roughness ntawm Qhov Chaw: Kev Cuam Tshuam rau Kev Ntsuas
Qhov roughness ntawm qhov chaw kuj txawv ntawm cov qib. Cov phaj qib A raug cov txheej txheem lapping thiab polishing ntau dua, ua rau qhov chaw du nrog qhov roughness nruab nrab (Ra) feem ntau qis dua 0.0005 ntiv tes. Qhov tiav du no txo qhov kev sib txhuam thiab tiv thaiv kev khawb ntawm cov khoom me me thaum ntsuas. Cov phaj qib B, nrog tus nqi Ra ntawm kwv yees li 0.001 ntiv tes, yog coarser. Txawm hais tias lawv tseem tuaj yeem ua cov haujlwm ntsuas yooj yim, lawv yuav tsis haum rau kev tuav cov khoom rhiab heev.
Cov Xwm Txheej Thov: Sib phim rau Cov Kev Xav Tau
Qhov kev xaiv ntawm Qib A thiab Qib B nyob ntawm seb daim ntawv thov yog dab tsi. Hauv kev tsim khoom siv dav hlau thiab semiconductor, qhov twg qhov kev ntsuas micrometer - qib yog qhov tseem ceeb, Cov phaj Qib A yog qhov zoo dua. Piv txwv li, thaum ntsuas qhov tiaj tus ntawm lub hniav turbine lossis kev sib dhos ntawm microchips, txawm tias qhov kev hloov pauv me me tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom. Txawm li cas los xij, Cov phaj Qib B feem ntau siv rau hauv kev tsim khoom tsheb, kev siv tshuab dav dav, thiab cov tsev kawm ntawv. Lawv txaus rau kev kuaj xyuas qhov loj me ntawm cov cav lossis qhia cov ntsiab cai ntsuas yooj yim yam tsis tas yuav tsum muaj kev ntsuas siab heev.
Cov Txheej Txheem Tsim Khoom thiab Tus Nqi: Kev Sib Pauv Yuav Tsum Xav Txog
Cov phaj qib A xav tau cov txheej txheem tsim khoom zoo dua. Cov kws ua tes siv sijhawm ntau dua los xaiv cov khoom siv, txiav kom raug, thiab txhuam ntau theem kom ua tiav qhov tiaj tiaj thiab qhov chaw tiav. Qib siab dua ntawm kev ua tes ua no, nrog rau qhov xav tau kev tswj xyuas zoo, ua rau cov nqi tsim khoom nce siab. Yog li ntawd, cov phaj qib A feem ntau kim dua li cov phaj qib B 30 - 50%. Rau cov lag luam uas xav tau nyiaj ntau lossis cov ntawv thov uas tsis tas yuav tsum tau ua kom raug, cov phaj qib B muab lwm txoj hauv kev pheej yig.
Hauv kev xaus, Qib A thiab Qib B granite nto phaj ua haujlwm rau ntau qib ntawm kev ua kom raug thiab kev xav tau daim ntawv thov. Thaum Qib A ua tau zoo hauv qib siab, qhov tseeb - tsav ib puag ncig, Qib B muab kev ua tau zoo txhim khu kev qha ntawm tus nqi qis dua rau kev siv dav dav. Los ntawm kev soj ntsuam qhov sib txawv no, cov chaw tsim khoom thiab cov neeg siv tuaj yeem txiav txim siab tau zoo uas ua kom zoo dua ob qho tib si kev ua kom raug thiab tus nqi - ua haujlwm tau zoo.
