Granite precision nto daim hlau tau ntev tau suav tias yog ib qho ntawm feem txhim khu kev qha hauv paus hauv kev ntsuas ntsuas. Lawv muab qhov chaw ruaj khov rau kev tshuaj xyuas, ntsuas, thiab ntsuas qhov tseeb thoob plaws kev lag luam xws li kev tsim khoom semiconductor, aerospace, CNC machining, thiab optical metrology. Thaum lawv qhov tseem ceeb tsis tau nug, muaj ib qho kev txhawj xeeb uas feem ntau tshwm sim hauv kev sib tham thiab cov neeg siv khoom nug:Yuav ua li cas humidity cuam tshuam rau granite nto daim hlau?Cov dej noo puas tuaj yeem ua rau granite deform lossis poob nws qhov tseeb?
Cov lus teb, raws li kev tshawb fawb thiab ntau xyoo ntawm kev lag luam kev lag luam, yog qhov tseeb. Granite, tshwj xeeb yog high-density dub granite, yog ib qho khoom siv ruaj khov heev nrog cov khoom tsis zoo hygroscopic. Tsis zoo li cov pob zeb ntxeem tau xws li marble lossis limestone, granite yog tsim los ntawm qeeb crystallization ntawm magma tob hauv lub ntiaj teb lub pob zeb. Cov txheej txheem no ua rau cov qauv ntom ntom nrog cov porosity tsawg heev. Hauv cov ntsiab lus, qhov no txhais tau hais tias granite tsis nqus dej los ntawm huab cua, thiab nws tsis o los yog deform nyob rau hauv qhov chaw ntub dej.
Qhov tseeb, qhov no tiv thaiv kom ya raws yog ib qho ntawm cov laj thawj tseem ceeb vim li cas granite tau hloov cam khwb cia hlau hauv ntau daim ntawv thov kev ntsuas. Qhov twg cam khwb cia hlau yuav xeb lossis corrode thaum raug cov av noo siab, granite tseem muaj tshuaj lom neeg ruaj khov. Txawm tias nyob rau hauv kev cob qhia nrog cov txheeb ze av noo siab tshaj 90%, precision granite daim hlau tuav lawv seem stability thiab flatness. Kev ntsuam xyuas tau ua nyob rau hauv ib puag ncig tswj tau lees paub tias qhov flatness ntawm granite nto phaj tseem nyob hauv micrometer kam rau ua tsis hais txog kev hloov pauv hauv huab cua noo.
Uas tau hais tias, thaum granite nws tus kheej tsis cuam tshuam los ntawm cov av noo, tag nrho qhov ntsuas ib puag ncig tseem tseem ceeb. Condensation tuaj yeem tshwm sim hauv cov chaw ua haujlwm tsis zoo thaum kub poob dheev, thiab txawm hais tias granite tsis xeb, cov dej condensed tuaj yeem tawm hauv qab plua plav lossis cov khoom paug uas cuam tshuam rau kev ntsuas. Cov cuab yeej muab tso rau hauv granite, xws li dial gauges, hluav taws xob theem, lossis kev sib koom tes ntsuas tshuab, feem ntau rhiab rau ib puag ncig zoo dua li granite puag nws tus kheej. Vim li no, lub chaw soj nstuam thiab kev cob qhia tau txhawb kom muaj kev ruaj khov ntawm qhov kub thiab txias tsis yog rau granite nkaus xwb tab sis kuj rau cov cuab yeej uas nyob ntawm nws.
Qhov zoo tshaj noo noo tsis kam ntawm granite yog tshwj xeeb tshaj yog muaj nqis nyob rau hauv kev lag luam uas ib puag ncig tej yam kev mob yog nyuaj rau tswj. Semiconductor fabs, aerospace cov chaw, thiab cov chaw soj ntsuam kev tshawb fawb feem ntau ua haujlwm nrog cov qauv ib puag ncig nruj, tab sis granite qhov ruaj khov ua kom muaj kev ruaj ntseg ntxiv. Hauv cov cheeb tsam uas muaj huab cua ntub, los ntawm cov teb chaws Asia mus rau ntug dej hiav txwv Europe, granite nto daim hlau tau ua pov thawj kom ntseeg tau ntau dua li lwm txoj hauv kev.
Ntawm ZHHIMG®, cov granite dub xaiv rau cov khoom precision muaj ntau dua qib ntawm kev ua tau zoo. Nrog rau qhov ceev ntawm kwv yees li 3100 kg ib lub cubic meter thiab qhov nqus dej tsawg dua 0.1%, nws muab qhov tsis sib haum xeeb. Qhov no ua kom ntseeg tau tias flatness thiab raug yog khaws cia nyob rau lub sij hawm ntev ntawm kev siv. Cov neeg muas zaub nyob rau hauv semiconductor manufacturing, optics, CNC machining, thiab lub teb chaws metrology institutes cia siab rau cov khoom no thaum yuav tsum tau precision.
Lwm qhov yuav tsum tau xav txog yog kev saib xyuas. Txawm hais tias granite tsis cuam tshuam los ntawm kev ya raws, kev coj ua zoo tshaj plaws pab txhawb nws lub neej kev pabcuam. Kev tu tsis tu ncua nrog ib daim ntaub tsis muaj lint yuav tiv thaiv cov plua plav. Cov npog tiv thaiv tuaj yeem ua kom qhov chaw tsis muaj pa tawm thaum lub phaj tsis siv. Periodic calibration nrog cov cuab yeej muaj ntawv pov thawj txheeb xyuas qhov tseeb nyob rau lub sijhawm ntev, thiab qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv high-precision ib puag ncig uas kam rau ua tau mus txog qib sub-micron. Nyob rau hauv tag nrho cov no, granite qhov inherent tsis kam rau cov av noo ua rau txoj hauj lwm yooj yim dua thiab kwv yees ntau dua nrog cov hlau los yog lwm yam ntaub ntawv.
Cov lus nug ntawm cov av noo thiab granite precision daim hlau feem ntau yog los ntawm kev txhawj xeeb ntawm ntuj: nyob rau hauv precision engineering, txawm tias qhov tsawg tshaj plaws ib puag ncig cuam tshuam tuaj yeem ntsuas tau. Piv txwv li, qhov kub thiab txias yog qhov tseem ceeb hauv qhov kev ruaj ntseg ntawm qhov ntev. Granite qhov qis coefficient ntawm thermal expansion twb ua rau nws yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau kev tswj qhov sib txawv no. Thaum nws los txog rau ya raws, txawm li cas los xij, engineers tuaj yeem so kom paub tseeb tias granite yog ib qho kev xaiv zoo tshaj plaws muaj.
Rau cov tuam txhab thiab cov chaw soj nstuam uas nqis peev ntau rau hauv kev tsim kho metrology, kev xaiv cov khoom siv tsis yog hais txog kev ua tau zoo niaj hnub no tab sis kuj hais txog kev ruaj ntseg rau ntau xyoo tom ntej. Granite tau ua pov thawj nws tus kheej los ua tus khub mus sij hawm ntev hauv txoj haujlwm no. Nws tiv taus cov av noo txhais tau hais tias nws tuaj yeem ntsia tau thiab siv ntau qhov chaw, los ntawm chav huv huv mus rau cov chaw ua haujlwm hnyav, tsis muaj kev txhawj xeeb tias cov dej noo yuav ua rau nws qhov tseeb.
Hauv kev xaus, cov av noo tsis ua rau muaj kev hem thawj rau kev ruaj ntseg lossis qhov tseeb ntawm granite nto daim hlau. Ua tsaug rau nws ntom, tsis yog-hygroscopic xwm, granite tseem tsis muaj kev cuam tshuam los ntawm cov dej noo thiab txuas ntxiv kom muab cov ntaub ntawv ruaj khov uas yuav tsum tau ua hauv niaj hnub notrology. Txawm hais tias kev tswj hwm ib puag ncig tseem ceeb rau cov cuab yeej thiab qhov tseeb tag nrho, granite nws tus kheej tuaj yeem ntseeg tau los tiv thaiv cov av noo cuam tshuam txog kev hloov pauv. Qhov no yog vim li cas, thoob plaws kev lag luam thiab thoob ntiaj teb, granite tseem yog cov khoom ntawm kev xaiv rau precision ntsuas lub hauv paus.
Ntawm ZHONGHUI Group (ZHHIMG®), qhov kev paub no tsis yog tsuas yog theoretical tab sis muaj pov thawj txhua hnub hauv kev koom tes nrog Fortune 500 tuam txhab, cov tsev kawm qib siab, thiab lub koom haum metrology hauv tebchaws. Rau cov engineers nrhiav kev cia siab rau lub sijhawm ntev, granite nto daim hlau sawv cev tsis yog kev coj noj coj ua nkaus xwb tab sis kuj yog yav tom ntej ntawm kev ntsuas ultra-precision.
