Cov khoom granite precision ua lub luag haujlwm tseem ceeb hauv kev tshuaj xyuas qhov ntev, ua haujlwm ua cov qauv siv rau kev txheeb xyuas qhov geometry ntawm ib feem, kuaj xyuas cov qauv yuam kev, thiab txhawb nqa kev ua haujlwm layout siab. Lawv qhov ruaj khov, rigidity, thiab kev tiv thaiv kev hloov pauv mus sij hawm ntev ua rau granite yog cov khoom siv ntseeg tau thoob plaws hauv cov chaw kuaj metrology, cov neeg tsim khoom siv tshuab, thiab cov chaw tsim khoom ultra-precision. Txawm hais tias granite paub dav tias yog pob zeb ruaj khov, nws tus cwj pwm ua qhov chaw siv metrological ua raws li cov ntsiab cai geometric tshwj xeeb - tshwj xeeb tshaj yog thaum lub hauv paus siv tau rov teeb tsa thaum lub sijhawm calibration lossis kev tshuaj xyuas.
Granite yog los ntawm cov magma uas txias qeeb qeeb hauv lub ntiaj teb lub plhaub. Nws cov qauv noob sib xws, cov zaub mov sib txuas ua ke zoo, thiab lub zog compressive zoo heev ua rau nws ruaj khov mus sij hawm ntev uas xav tau rau kev ua vaj tse precision. Tshwj xeeb tshaj yog cov granite dub zoo muaj kev ntxhov siab tsawg kawg nkaus sab hauv, cov qauv crystalline zoo, thiab kev tiv taus kev hnav thiab kev cuam tshuam ntawm ib puag ncig. Cov yam ntxwv no piav qhia vim li cas granite tsis yog siv rau hauv cov hauv paus tshuab thiab cov rooj tshuaj xyuas xwb tab sis kuj siv rau kev siv sab nraum zoov uas xav tau qhov zoo nkauj thiab kev ruaj khov yuav tsum nyob ruaj khov rau ntau xyoo caum.
Thaum lub granite siv qhov chaw ntsuas hloov pauv datum—xws li thaum lub sijhawm calibration, kev tsim kho qhov chaw, lossis thaum hloov cov hauv paus ntsuas—tus cwj pwm ntawm qhov chaw ntsuas ua raws li cov cai kwv yees tau. Vim tias txhua qhov kev ntsuas qhov siab raug coj mus rau lub dav hlau siv, tilting lossis hloov lub datum hloov cov nqi lej sib piv rau qhov deb ntawm lub axis ntawm kev tig. Cov nyhuv no yog linear, thiab qhov loj ntawm kev nce lossis txo qis hauv qhov siab ntsuas ntawm txhua qhov chaw sib raug ncaj qha rau nws qhov deb ntawm kab pivot.
Txawm tias thaum lub dav hlau datum tig me ntsis los xij, qhov kev taw qhia ntawm kev ntsuas tseem nyob rau ntawm qhov chaw uas raug ntsuas. Qhov sib txawv ntawm lub kaum sab xis ntawm qhov ua haujlwm datum thiab qhov kev siv tshuaj xyuas yog me heev, yog li txhua qhov cuam tshuam tshwm sim yog qhov yuam kev thib ob thiab feem ntau tsis tseem ceeb hauv kev ntsuas qhov tseeb. Piv txwv li, kev ntsuam xyuas qhov tiaj tiaj yog raws li qhov sib txawv ntawm cov ntsiab lus siab tshaj plaws thiab qis tshaj plaws, yog li kev hloov pauv ntawm datum tsis cuam tshuam rau qhov tshwm sim kawg. Yog li ntawd, cov ntaub ntawv lej tuaj yeem raug tshem tawm los ntawm tib tus nqi thoob plaws txhua qhov ntsiab lus yam tsis hloov pauv qhov tshwm sim tiaj tiaj.
Qhov kev hloov pauv ntawm cov nqi ntsuas thaum lub sijhawm hloov kho datum tsuas yog qhia txog kev txhais lus geometric lossis kev tig ntawm lub dav hlau siv. Kev nkag siab txog tus cwj pwm no yog qhov tseem ceeb rau cov kws kho tshuab uas kho cov granite nto lossis tshuaj xyuas cov ntaub ntawv ntsuas, kom ntseeg tau tias cov kev hloov pauv ntawm cov lej raug txhais kom raug thiab tsis yuam kev rau qhov sib txawv ntawm qhov chaw tiag tiag.
Kev tsim cov khoom siv granite precision kuj xav tau cov txheej txheem kho tshuab nruj heev. Cov tshuab pabcuam siv los ua cov pob zeb yuav tsum tau khaws cia kom huv si thiab zoo, vim tias kev ua qias tuaj yeem ua rau muaj kev puas tsuaj lossis kev xeb sab hauv tuaj yeem ua rau muaj kev raug. Ua ntej machining, cov khoom ntawm cov khoom siv yuav tsum tau kuaj xyuas rau cov burrs lossis qhov tsis zoo ntawm qhov chaw, thiab yuav tsum tau siv lubrication qhov twg xav tau kom ntseeg tau tias kev txav mus los du. Kev kuaj xyuas qhov ntev yuav tsum tau rov ua dua thoob plaws hauv kev sib dhos kom paub tseeb tias cov khoom kawg ua tau raws li qhov kev qhia tshwj xeeb. Kev sim khiav yog qhov tsim nyog ua ntej kev machining raug cai pib; kev teeb tsa tshuab tsis raug tuaj yeem ua rau chipping, poob khoom ntau dhau, lossis tsis sib xws.
Granite nws tus kheej yog tsim los ntawm feldspar, quartz, thiab mica, nrog rau cov quartz feem ntau ncav cuag txog li ib nrab ntawm tag nrho cov khoom xyaw mineral. Nws cov silica ntau pab ncaj qha rau nws qhov nyuaj thiab qis hnav. Vim tias granite ua tau zoo dua ceramics thiab ntau yam khoom siv hluavtaws hauv kev ruaj khov ntev, nws yog siv dav tsis yog hauv metrology tab sis kuj hauv pem teb, architectural cladding, thiab cov qauv sab nraum zoov. Nws txoj kev tiv thaiv corrosion, tsis muaj magnetic teb, thiab tsawg thermal expansion ua rau nws hloov pauv zoo rau cov hlau cam khwb cia ib txwm muaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas xav tau kev ruaj khov kub thiab kev ua haujlwm tas mus li.
Hauv kev ntsuas qhov tseeb, granite muaj lwm qhov zoo dua: thaum qhov chaw ua haujlwm raug khawb lossis ntaus tsis raug, nws tsim ib lub qhov me me es tsis yog lub burr tsa. Qhov no tiv thaiv kev cuam tshuam hauv zos nrog kev txav mus los ntawm cov cuab yeej ntsuas thiab tswj hwm kev ncaj ncees ntawm lub dav hlau siv. Cov khoom siv tsis warp, tiv taus hnav, thiab tswj hwm geometric stability txawm tias tom qab ntau xyoo ntawm kev ua haujlwm tas mus li.
Cov yam ntxwv no tau ua rau cov granite precision yog ib yam khoom tseem ceeb hauv cov txheej txheem tshuaj xyuas niaj hnub. Kev nkag siab txog cov ntsiab cai geometric tom qab kev hloov pauv datum, ua ke nrog kev ua haujlwm kom raug thiab kev saib xyuas cov khoom siv siv los ua granite, yog qhov tseem ceeb rau kev ua kom txhua qhov chaw siv tau zoo thoob plaws nws lub neej kev pabcuam.
