Cov teeb meem me me ntawm qhov chaw cuam tshuam rau qhov tseeb ntawm kev teeb tsa ntawm cov khoom siv kho qhov muag
Txawm hais tias cov qauv granite nyuaj, tab sis thaum lub sijhawm ua tiav, nws qhov chaw tseem yuav tsim cov kab nrib pleb me me, cov qhov xuab zeb thiab lwm yam tsis zoo. Cov qhov tsis zoo me me no tsis pom tseeb rau lub qhov muag liab qab, tab sis tuaj yeem muaj kev cuam tshuam loj rau kev teeb tsa cov khoom siv kho qhov muag. Piv txwv li, thaum lub lens kho qhov muag siab raug teeb tsa rau ntawm lub platform granite nrog cov qhov tsis zoo me me, qhov sib haum zoo tagnrho ntawm lub lens thiab lub platform tsis tuaj yeem ua tiav, ua rau qhov chaw kho qhov muag ntawm lub lens kho qhov muag raug tshem tawm, uas cuam tshuam rau qhov tseeb ntawm txoj kev kho qhov muag ntawm tag nrho cov khoom siv kho qhov muag, thiab thaum kawg txo qhov tseeb ntawm kev kuaj pom.
Qhov kev tso tawm ntawm kev ntxhov siab sab hauv cov khoom ua rau deformation ntawm lub platform
Txawm hais tias granite tom qab lub sijhawm ntev ntawm lub neej ntuj, tab sis nyob rau hauv cov txheej txheem mining, kev ntxhov siab sab hauv tseem yuav hloov pauv. Raws li lub sijhawm, cov kev ntxhov siab no maj mam tso tawm, uas tuaj yeem ua rau lub platform granite deformation. Hauv cov khoom siv tshuaj xyuas optical nrog cov kev xav tau siab, txawm tias qhov deformation me me heev kuj tuaj yeem ua rau qhov kev hloov pauv ntawm txoj kev pom kev. Piv txwv li, hauv cov cuab yeej pom kev pom kev xws li laser interferometers, qhov kev hloov pauv me ntsis ntawm lub platform yuav ua rau qhov kev hloov pauv ntawm cov kev cuam tshuam, ua rau muaj qhov yuam kev hauv cov txiaj ntsig ntsuas thiab cuam tshuam loj heev rau kev ntseeg siab ntawm cov ntaub ntawv pom.
Nws nyuaj rau phim cov coefficient thermal expansion ntawm cov khoom siv kho qhov muag
Cov khoom siv tshuaj xyuas qhov muag feem ntau ua haujlwm hauv qhov chaw kub sib txawv, lub sijhawm no, qhov sib txawv ntawm cov coefficient thermal expansion ntawm granite thiab cov khoom siv kho qhov muag ua rau muaj kev cov nyom loj. Thaum qhov kub thiab txias hloov pauv, vim yog cov coefficient thermal expansion tsis sib xws ntawm ob qho, nws yuav tsim cov degree sib txawv ntawm kev nthuav dav, uas yuav ua rau muaj kev hloov pauv lossis kev ntxhov siab ntawm cov khoom siv kho qhov muag thiab lub platform granite, yog li cuam tshuam rau qhov tseeb thiab kev ruaj khov ntawm lub kaw lus kho qhov muag. Piv txwv li, hauv qhov chaw kub qis, qib kev sib txhuam ntawm granite txawv ntawm cov iav kho qhov muag, uas yuav ua rau cov khoom siv kho qhov muag xoob thiab cuam tshuam rau kev ua haujlwm ib txwm ntawm cov khoom siv kuaj pom.

Cov txheej txheem kho qhov chaw siab precision
Siv cov thev naus laus zis sib tsoo thiab polishing siab heev, cov granite nto raug ua tiav nrog kev ua haujlwm siab heev. Los ntawm ntau cov txheej txheem sib tsoo zoo, nrog cov khoom siv CNC siab, tuaj yeem tshem tawm cov qhov tsis zoo me me ntawm qhov chaw, kom qhov chaw ntawm granite tiaj tus mus txog qib nanometer. Tib lub sijhawm, cov thev naus laus zis tshiab xws li ion beam polishing siv los ua kom zoo dua qhov zoo ntawm qhov chaw, xyuas kom meej tias cov khoom siv kho qhov muag tuaj yeem ntsia tau raws li qhov tseeb, txo qhov kev hloov pauv ntawm txoj kev kho qhov muag los ntawm qhov tsis zoo ntawm qhov chaw, thiab txhim kho qhov tseeb ntawm cov khoom siv tshuaj xyuas kho qhov muag.
Kev txo kev ntxhov siab thiab kev saib xyuas mus sij hawm ntev
Ua ntej ua granite, qhov tob ntawm thermal aging thiab vibration aging kev kho mob kom siab tshaj plaws kev tso tawm ntawm kev ntxhov siab sab hauv. Tom qab ua tiav qhov machining, cov thev naus laus zis nrhiav kev ntxhov siab siab heev siv los ua kev soj ntsuam kev ntxhov siab ntawm lub platform. Tib lub sijhawm, tsim cov ntaub ntawv saib xyuas cov khoom siv mus sij hawm ntev, thiab tsis tu ncua ntes qhov deformation ntawm lub granite platform. Thaum pom qhov me me deformation los ntawm kev tso tawm kev ntxhov siab, nws raug kho raws sijhawm los ntawm cov txheej txheem kho kom raug kom ntseeg tau tias lub platform ruaj khov thaum siv mus sij hawm ntev thiab muab lub hauv paus txhim khu kev qha rau cov khoom siv tshuaj xyuas qhov muag.
Kev tswj hwm thermal thiab kev sib phim cov khoom siv zoo dua
Vim muaj qhov sib txawv ntawm cov coefficient ntawm thermal expansion, ntawm ib sab tes, ib lub tshuab tswj thermal tshiab tau tsim los tswj qhov kub hauv cov khoom siv kho qhov muag kom ruaj khov los ntawm kev tswj nws kom raug, txo qhov nthuav dav ntawm cov khoom siv los ntawm kev hloov pauv kub. Ntawm qhov tod tes, thaum xaiv cov khoom siv, xav txog qhov sib phim ntawm cov coefficient thermal expansion ntawm granite thiab cov khoom siv kho qhov muag, xaiv cov granite uas muaj cov coefficient thermal expansion zoo sib xws, thiab ua qhov kev tsim kho kom zoo sib xws ntawm cov khoom siv kho qhov muag. Tsis tas li ntawd, cov ntaub ntawv nruab nrab lossis cov qauv sib txuas yooj ywm kuj tseem siv tau los txo qhov kev ntxhov siab los ntawm qhov sib txawv ntawm thermal expansion ntawm ob qho tib si, kom ntseeg tau tias lub tshuab kho qhov muag tuaj yeem ua haujlwm ruaj khov hauv qhov chaw kub sib txawv, thiab txhim kho qhov kev hloov pauv ib puag ncig thiab kev kuaj pom tseeb ntawm cov khoom siv kuaj pom.
