Cov cuab yeej ntsuas qhov tseeb ntawm granite (cov kav plaub fab, cov kab ncaj, cov kav kaum sab xis, thiab lwm yam) ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw siab vim lawv qhov kev ua haujlwm siab, kev ruaj khov siab thiab kev tiv thaiv corrosion muaj zog.
Hauv kev ua cov khoom siv precision, nws yog siv rau kev ntsuas qhov ncaj ntawm cov hlau qhia thiab qhov tiaj tiaj ntawm cov rooj ua haujlwm hauv cov cuab yeej tshuab CNC, cov chaw machining thiab lwm yam khoom siv. Nrog rau qhov coefficient thermal expansion qis li (4-8) × 10⁻⁶ / ℃, nws tuaj yeem tiv taus qhov cuam tshuam ntawm qhov kub nce thaum lub sijhawm ua haujlwm ntawm cov cuab yeej tshuab. Thaum tshuaj xyuas cov khoom precision, nws qhov chaw qis-roughness yuav tsis khawb cov khoom ua haujlwm thiab tiv taus roj xeb.
Cov lag luam aerospace thiab kev tiv thaiv muaj cov kev cai nruj heev rau kev ua kom raug. Cov cuab yeej ntsuas granite yog siv los ntsuas cov khoom siv tenon ntawm cov hniav cav dav hlau thiab tshuaj xyuas cov nplaim ntawm cov cabins missile, thiab lwm yam. Nws cov yam ntxwv damping siab tuaj yeem nqus tau qhov kev co hauv lub Hoobkas. Nws muaj kev ruaj khov tshuaj lom neeg muaj zog thiab tuaj yeem hloov kho rau qhov chaw ua haujlwm tshwj xeeb ntawm lub Hoobkas aerospace, kom ntseeg tau tias qhov tseeb ntawm kev tsim khoom ntawm cov khoom tseem ceeb.
Hauv kev tsim khoom siv hluav taws xob thiab semiconductor, cov cuab yeej ntsuas granite siv rau kev ntsuas cov kev taw qhia hauv cov khoom siv xws li cov tshuab photolithography thiab cov tshuab wafer dicing, nrog rau kev tshuaj xyuas cov khoom siv ntim khoom. Nws tus yam ntxwv ntawm tsis muaj hlau ion precipitation zam kev ua qias tuaj rau lub chaw ua haujlwm semiconductor huv si, xyuas kom meej qhov tseeb ntawm nano-scale lithography thiab qhov zoo ntawm SMT patch soldering.
Cov chaw kuaj thiab tshawb fawb txog kev ntsuas ntsuas siv cov cuab yeej ntsuas granite ua cov qauv los ntsuas lwm cov cuab yeej ntsuas hlau. Lawv muaj kev khaws cia qhov tseeb zoo heev rau lub sijhawm ntev, thiab qhov hloov pauv ntawm qhov tiaj tiaj tom qab 10 xyoo siv yog ≤ ± 0.5μm / m. Nws kuj tseem siv tau ua cov ntaub ntawv ntsuas qhov tseeb siab hauv kev tshawb fawb txog cov ntaub ntawv thiab kev sim ua vaj tse kho qhov muag.
Tsis tas li ntawd xwb, cov cuab yeej ntsuas granite kuj tseem siv rau hauv kev tsim cov khoom siv kho mob thiab cov cuab yeej siv kho qhov muag, xws li kev ntsuas cov pob qij txha ntawm cov neeg hlau phais thiab cov hauv paus ntawm cov khoom siv tsom iav astronomical, kom ntseeg tau tias cov khoom siv ua tiav qhov tseeb ntawm qhov chaw sub-millimeter thiab cov teebmeem saib xyuas tsis muaj kev cuam tshuam. Nrog rau kev ua tau zoo tshaj plaws, cov cuab yeej ntsuas granite precision tau dhau los ua "lub hauv paus tseem ceeb" ntawm kev tsim khoom siab.
