Hauv kev ua haujlwm precision engineering thiab metrology, cov khoom siv granite precision - xws li cov phaj saum npoo, cov hauv paus tshuab, thiab cov rooj optical - tau hwm rau lawv qhov kev ruaj khov tshwj xeeb, qhov nyuaj, thiab kev tiv thaiv corrosion. Ib qho khoom granite zoo, thaum saib xyuas kom zoo, tuaj yeem tswj nws qhov calibration thiab flatness rau ntau xyoo, ua lub hauv paus ruaj khov rau koj cov kev ntsuas tseem ceeb tshaj plaws. Txawm li cas los xij, txawm tias cov granite ruaj khov tshaj plaws tsis tiv thaiv kev cuam tshuam ntawm nws ib puag ncig thiab kev siv. Kev tswj hwm qhov calibration mus sij hawm ntev tsis yog ib qho kev teeb tsa ib zaug xwb; nws yog ib qho kev qhuab qhia tas mus li uas yuav tsum muaj kev nkag siab tob txog kev tswj hwm ib puag ncig, kev ua haujlwm zoo, thiab kev saib xyuas ua ntej.
Kev Tswj Xyuas Lub Hauv Paus Ib Puag Ncig
Tus yeeb ncuab loj tshaj plaws ntawm kev kho kom ntev mus ntev tsis yog kev hnav thiab tsim kua muag txhua hnub, tab sis qhov chaw tsis tswj hwm. Yuav kom ntseeg tau tias koj cov khoom granite khaws cia lawv qhov tseeb ntawm qib micron, koj yuav tsum tsim kom muaj lub hauv paus ruaj khov.
Kub yog qhov tseem ceeb tshaj plaws. Granite muaj qhov coefficient qis heev ntawm thermal expansion, tab sis nws tsis yog xoom. Rau qib siab tshaj plaws ntawm kev raug, cov khoom yuav tsum tau muab tso rau hauv chav kuaj metrology uas tswj tau qhov kub thiab txias, zoo tagnrho khaws cia ntawm qhov kub tas li ntawm 20 ° C (± 2 ° C). Kev hloov pauv kub tam sim ntawd lossis kev raug tshav ntuj ncaj qha, cov cua txias, thiab cov kav dej cua sov tuaj yeem ua rau muaj kev hloov pauv thermal hauv zos. Cov kev hloov pauv no tsim kev ntxhov siab sab hauv hauv lub pob zeb, ua rau muaj kev hloov pauv me me ib ntus tab sis tseem ceeb uas ua rau kev ntsuas qhov tseeb puas tsuaj. Ntxiv mus, cov khoom ua haujlwm loj lossis cov thaiv ntsuas yuav tsum tau tso cai rau kev hloov pauv ntawm qhov chaw granite rau ob peb teev ua ntej ntsuas kom tiv thaiv kev hloov pauv cua sov los ntawm kev cuam tshuam cov txiaj ntsig.
Qhov tseem ceeb ib yam li ntawd yog lub hauv paus teeb tsa. Ib feem ntawm granite tsuas yog ruaj khov li qhov nws zaum rau. Nws yuav tsum tau muab tso rau ntawm lub hauv paus ruaj khov, tsis muaj kev co. Hauv qhov chaw siab, qhov no feem ntau txhais tau tias siv cov ntaub so ntswg lossis pneumatic vibration cais tawm kom tshem tawm granite ntawm kev co hauv pem teb los ntawm cov tshuab nyob ze, forklifts, lossis txawm tias kev taug kev. Thaum teeb tsa lub phaj saum npoo loj, kev txhawb nqa kom zoo tsis tuaj yeem sib tham. Nws yuav tsum so ntawm peb-taw tes lossis tsib-taw tes txhawb nqa (feem ntau peb lub ntsiab lus tseem ceeb tsim ib daim duab peb sab isosceles thiab ob lub ntsiab lus pabcuam). Qhov kev teeb tsa no tiv thaiv kev ntxhov siab sab hauv thiab "co," kom ntseeg tau tias lub phaj nyob rau hauv nws qhov ntuj tshaj plaws, tsis muaj kev ntxhov siab. Tom qab thawj zaug leveling, nws raug pom zoo kom cia cov khoom zaum tsis cuam tshuam rau 12 txog 24 teev kom tso cai rau txhua qhov kev ntxhov siab seem kom ploj mus ua ntej ua qhov kev nyeem ntawv calibration kawg.
Kev Tswj Xyuas Txhua Hnub thiab Kev Ua Haujlwm Zoo Tshaj Plaws
Thaum twg ib puag ncig raug tswj hwm lawm, lub sijhawm ntev ntawm koj lub granite calibration nyob ntawm seb nws raug kho li cas thaum lub sijhawm ua haujlwm txhua hnub. Qhov chaw ntawm lub phaj granite yog nws cov khoom muaj nqis tshaj plaws, thiab kev tiv thaiv nws ntawm kev puas tsuaj lub cev yog qhov tseem ceeb.
Nco ntsoov xyuas kom meej tias qhov chaw granite huv si ua ntej thiab tom qab siv. Cov hmoov av, cov hlau tawg, thiab cov khoom me me yog cov ua rau khawb ntawm qhov chaw. Siv daim ntaub mos mos, tsis muaj plaub mos mos uas ntub me ntsis nrog cov tshuaj ntxuav pH nruab nrab lossis cawv ntshiab kom so qhov chaw. Tsis txhob siv cov tshuaj lom neeg hnyav lossis cov tshuaj alkaline, vim tias lawv tuaj yeem ua rau lub pob zeb nto qeeb qeeb. Thaum muab cov khoom ua haujlwm tso rau ntawm lub phaj, tsis txhob swb lossis rub lawv. Hloov chaw, tsa thiab maj mam tso lawv cia. Rau cov khoom hnyav, siv cov jacks lossis hoists kho tau los faib qhov hnyav kom sib npaug thiab tiv thaiv cov khoom thauj uas tuaj yeem ua rau muaj kev ntxhov siab hauv zos lossis chipping.
Nws tseem ceeb heev uas yuav tsum nco ntsoov tias lub phaj granite tsis yog dab tsi. Nws tsis yog lub rooj ua haujlwm, lub anvil, lossis hloov lwm yam cuab yeej. Tsis txhob siv qhov chaw rau kev sau ntawv, ntaus, lossis ua lub hauv paus rau kev ua haujlwm tshuab hnyav uas yuav ua rau muaj kev puas tsuaj. Tsis tas li ntawd, cov khoom siv hlau nplaum yuav tsum tau demagnetized ua ntej muab tso rau ntawm lub phaj. Cov hlau nplaum seem tuaj yeem nyiam cov hlau me me los ntawm huab cua, uas tom qab ntawd tuaj yeem ua haujlwm ua abrasive nyob rau hauv ib qho chaw txav mus los, maj mam khawb qhov chaw raug.
Kev Txij Nkawm Ua Ntej thiab Kev Kho Dua Tshiab Tsis Tu Ncua
Txawm tias muaj kev tswj hwm ib puag ncig zoo meej thiab kev tswj hwm maj mam, kev kho kom zoo mus sij hawm ntev yuav tsum muaj lub sijhawm saib xyuas zoo. Granite yog ib yam khoom siv ntuj, thiab ntau xyoo, nws tuaj yeem hloov pauv me ntsis vim yog cov khoom siv nkag mus lossis poob. Yog li ntawd, kev cia siab rau kev kho kom zoo thawj zaug ntawm lub Hoobkas yog qhov kev pheej hmoo uas tsis muaj lub chaw kuaj mob yuav tsum ua.
Siv cov txheej txheem txheeb xyuas qib. Txhua hnub lossis txhua lub lim tiam, cov neeg ua haujlwm yuav tsum ua qhov kev tshuaj xyuas sai sai rau qhov puas tsuaj ntawm qhov chaw thiab kev kuaj xyuas qhov tiaj tiaj siv lub ntsuas qhov tseeb lossis lub ntug ncaj uas tau teeb tsa. Qhov no pab ntes txhua yam teeb meem tam sim ntawd lossis kev hloov pauv loj heev.
Rau kev kho kom raug lub sijhawm ntev, teem sijhawm kho dua tshiab ntawm lub sijhawm tsis tu ncua, feem ntau txhua 6 txog 12 lub hlis, nyob ntawm seb siv ntau npaum li cas thiab qib kev kam rau siab xav tau. Cov txheej txheem no yuav tsum tau ua los ntawm cov kws tshaj lij metrology uas tsim nyog siv cov khoom siv taug qab, xws li cov cuab yeej ntsuas hluav taws xob siab lossis laser interferometers. Thaum lub sijhawm no, tag nrho qhov chaw raug luam theej duab (feem ntau hauv daim phiaj lossis "lub hnub qub" qauv) los tsim daim ntawv qhia topographical ntawm lub phaj. Yog tias pom muaj qhov sib txawv me me, cov kws tshaj lij feem ntau tuaj yeem ua qhov kho kom raug ntawm qhov chaw lapping lossis scraping kom coj qhov chaw rov qab mus rau nws qib DIN lossis ISO kev kam rau siab qub.
Los ntawm kev tswj hwm qhov chaw ib puag ncig kom zoo, ua raws li cov txheej txheem kev tswj hwm nruj, thiab cog lus rau lub sijhawm rov ua dua tshiab, koj ua kom koj cov khoom siv granite precision tseem yog tus qauv ntseeg siab. Qhov kev mob siab rau no tsis yog tsuas yog tiv thaiv koj cov peev txheej xwb tab sis, qhov tseem ceeb dua, lav qhov kev ncaj ncees thiab kev ntseeg siab ntawm txhua qhov kev ntsuas uas koj pab neeg tsim tawm.
