Cov phaj granite yog cov cuab yeej siv precision siv dav hauv metrology, kev tshuaj xyuas, thiab kev siv tshuab. Lawv yog ua los ntawm cov granite ntuj zoo, muaj nqis rau nws qhov ruaj khov, ruaj khov, thiab tiaj tus. Tab sis cov phaj no puas raug?
Kev Ruaj Ntseg Ntuj
Granite tau tsim los ntawm ntau lab xyoo dhau los hauv qab kev nyuaj siab thiab cua sov heev, ua rau muaj cov qauv ntom ntom thiab zoo. Qhov kev ruaj khov ntuj no ua rau granite yog cov khoom siv zoo tshaj plaws rau cov phaj saum npoo, vim nws tiv taus kev hloov pauv ntawm qhov kub thiab txias, av noo, thiab kev ntxhov siab ntawm lub cev. Qhov tseeb, granite muaj cov coefficient qis ntawm kev nthuav dav thermal, txhais tau tias nws nthuav dav thiab cog lus me ntsis nrog kev hloov pauv kub. Cov cuab yeej no ua kom ntseeg tau tias qhov chaw ntawm lub phaj tseem tiaj tus thiab tseeb, txawm tias nyob hauv qhov chaw nyuaj.
Kev Tsim Khoom Zoo
Yuav kom ua tiav qhov tseeb tshaj plaws, cov phaj granite nto yuav tsum tau ua cov txheej txheem tsim khoom nruj heev. Ua ntej, cov granite block raug xaiv ua tib zoo rau nws qhov zoo thiab sib xws. Tom qab ntawd, nws raug txiav kom loj thiab zoo li koj xav tau. Tom qab ntawd yog cov txheej txheem lapping thiab polishing, qhov twg qhov chaw raug maj mam ua kom zoo siv cov khoom siv abrasive. Cov txheej txheem no ua tau zoo heev tuaj yeem ua tiav qhov roughness qis heev thiab qhov siab flatness tolerances.
Cov Qauv Kev Tseeb
Qhov tseeb ntawm cov phaj granite nto feem ntau yog teev los ntawm lawv qhov kev kam rau siab. Raws li American Society of Mechanical Engineers (ASME) B89.3.7 tus qauv, cov phaj nto raug ntsuas raws li lawv qhov tiaj tus. Qib siab tshaj plaws, AA, muaj qhov kam rau siab tshaj plaws, ua rau nws tsim nyog rau cov chaw kuaj mob thiab cov ntsuas siab. Cov phaj qib A feem ntau siv rau hauv thaj chaw tshuaj xyuas, thaum cov phaj qib B, nrog rau qhov kam rau siab me ntsis, yuav pom ntawm cov khw hauv pem teb.
Piv txwv li, lub phaj granite loj 12" x 12" AA yuav muaj qhov siab ntawm ±0.00005 nti thoob plaws nws qhov chaw. Qib kev raug no tso cai rau kev ntsuas thiab kev kho kom raug ntawm lwm cov cuab yeej thiab cov khoom.
Cov Yam Cuam Tshuam Rau Qhov Tseeb
Txawm hais tias cov phaj granite nto yog qhov tseeb tiag, muaj ntau yam uas yuav cuam tshuam rau lawv txoj kev ua haujlwm dhau sijhawm. Kev siv tsis raug, xws li kev poob lossis kev siv zog ntau dhau ntawm lub phaj, tuaj yeem ua rau muaj cov kab nrib pleb lossis tawg uas yuav cuam tshuam rau qhov tiaj tus. Tsis tas li ntawd, cov yam ntxwv ib puag ncig xws li kev hloov pauv kub heev lossis cov av noo siab kuj tuaj yeem cuam tshuam rau qhov tseeb ntawm lub phaj. Kev ntxuav thiab kev saib xyuas tsis tu ncua, nrog rau kev khaws cia kom zoo, yog qhov tseem ceeb los khaws qhov tseeb ntawm lub phaj.
Xaus lus, cov phaj granite nto muaj qhov tseeb tshwj xeeb, ua rau lawv yog qhov kev xaiv txhim khu kev qha rau cov ntawv thov uas qhov tseeb yog qhov tseem ceeb. Lawv qhov ruaj khov ntuj, ua ke nrog cov txheej txheem tsim khoom raug, tso cai rau lawv los muab qhov chaw ruaj khov thiab raug rau ntau yam kev lag luam, los ntawm aerospace thiab automotive mus rau electronics thiab kev tsim khoom siv kho mob.
