Kev hloov pauv ntawm kev tsim khoom tau thawb qhov kev kam rau siab mus rau qhov txwv ntawm kev ntsuas, ua rau qhov chaw ntsuas qhov tseem ceeb dua li yav dhau los. Hauv plawv ntawm qhov chaw no yog lub rooj ntsuas granite, qhov chaw siv tseem ceeb tshaj plaws rau txhua qhov kev tshuaj xyuas lossis kev sib dhos ua ke. Nws yog qhov "zero point" uas ua pov thawj qhov tseeb ntawm ntau lab daus las cov tshuab, los ntawm Coordinate Measuring Machines (CMMs) mus rau cov theem tswj semiconductor.
Txawm li cas los xij, lo lus nug uas txhua tus kws ua haujlwm precision ntsib yog seb lawv lub rooj granite metrology tam sim no puas muaj peev xwm txhawb nqa qhov kev xav tau ntawm lub hnub nyoog nanometer. Cov lus teb nyob ntawm qhov zoo ntawm cov khoom siv, qhov kev ua haujlwm engineering siv thaum lub sijhawm tsim khoom, thiab tag nrho cov kev ruaj khov ntawm lub kaw lus.
Kev Tshawb Fawb Txog Khoom Siv ntawm Kev Ruaj Ntseg Tag Nrho
Kev xaiv cov khoom siv rau ib qholub rooj ntsuas granitetsis muaj kev sib tham hauv thaj chaw ultra-precision. Cov ntaub ntawv tsawg dua, xws li granites lossis marble, ua tsis tiav vim yog qhov tsis ruaj khov ntawm thermal thiab tsis txaus rigidity. Cov nto metrology-qib tiag tiag xav tau cov granite dub gabbro uas muaj qhov ceev siab.
Peb cov ZHHIMG® Black Granite tshwj xeeb raug xaiv tshwj xeeb rau nws cov yam ntxwv zoo tshaj plaws:
-
Qhov Ceev Tshwj Xeeb: Nrog qhov ceev ze li ntawm 3100 kg / m³, cov khoom siv muaj Young's modulus siab uas xav tau los tiv thaiv kev khoov thaum muaj kev thauj khoom hnyav. Qhov kev khov kho no yog qhov tseem ceeb rau kev tswj kom tiaj tus, tshwj xeeb tshaj yog rau cov rooj loj uas txhawb nqa cov khoom siv loj.
-
Thermal Inertia: Cov granite muaj qhov thermal expansion qis heev. Qhov thermal inertia zoo dua no txhais tau tias qhov loj ntawm lub rooj tseem yuav luag ruaj khov txawm tias muaj kev hloov pauv me me ntawm qhov kub hauv chav kuaj, tshem tawm qhov ua rau muaj qhov yuam kev ntsuas hauv cov ntawv thov rhiab heev.
-
Kev Tiv Thaiv Kev Co: Cov qauv pob zeb ntom ntom muab kev tiv thaiv kev co zoo heev tiv thaiv kev co ntawm ib puag ncig thiab tshuab, cais cov txheej txheem tshuaj xyuas rhiab heev ntawm suab nrov sab nraud.
Cov khoom siv no tau dhau los ntawm kev laus ua tib zoo thiab tswj tau kom tshem tawm cov kev ntxhov siab sab hauv, kom ntseeg tau tias lub rooj muaj qhov ntev thiab qhov ntev tau khaws cia rau ntau xyoo ntawm kev pabcuam - qhov no yog ib yam uas tsis yooj yim ua tiav nrog cov khoom siv tsim ua.
Kev Ua Zoo Tshaj Plaws Hauv Engineering: Los Ntawm Chaw Txiav Pob Zeb Mus Rau Kev Kho Kom Zoo
Kev tsim khoom siv high-endlub rooj ntsuas granitemuaj peev xwm ua tiav Qib 00 lossis Qib 000 qhov kev kam rau siab yog ib qho txheej txheem nruj uas sib xyaw ua ke lub peev xwm ua haujlwm loj heev nrog kev ua tiav me me. Nws yog ntau tshaj li kev txhuam yooj yim.
Cov txheej txheem xav tau ib puag ncig ruaj khov heev. Peb cov chaw muaj xws li cov chav loj loj, tswj tau huab cua uas ua rau ntawm cov pob zeb tuab, uas muaj kev co, feem ntau nyob ib puag ncig los ntawm cov qhov av tiv thaiv kev co. Ib puag ncig no yog qhov tseem ceeb vim tias cov theem kawg ntawm kev lapping thiab kev ntsuas yog qhov yooj yim rau kev cuam tshuam ib puag ncig.
Cov tshuab sib tsoo loj, tshwj xeeb siv rau kev ua kom zoo nkauj thawj zaug, tab sis qhov tseeb kawg, qhov tseem ceeb tshaj plaws yog ua tiav los ntawm kev siv tes ua haujlwm. Qhov no yog qhov uas tib neeg tsis tuaj yeem hloov pauv tau. Peb cov kws tshaj lij, uas siv ntau xyoo ntawm kev paub dhau los thiab cov cuab yeej rhiab heev, ua qhov kev kho zaum kawg, coj lub rooj kom tiaj tus, sib luag, thiab sib npaug raws li cov qauv thoob ntiaj teb xws li ASME B89.3.7 lossis DIN 876. Lawv lub peev xwm los tswj cov khoom tshem tawm ntawm qib sub-micron yog qhov txiav txim siab kawg ntawm qhov zoo ntawm lub rooj.
Kev taug qab thiab Daim Ntawv Pov Thawj: Lub Chaw Haujlwm Metrology
Lub rooj ntsuas granite metrology tsuas yog ntseeg tau raws li nws daim ntawv pov thawj. Txhua lub rooj yuav tsum muaj cov ntaub ntawv qhia txog kev taug qab, los xyuas kom meej tias nws cov geometric integrity siv cov cuab yeej siv siab tshaj plaws, suav nrog laser interferometers, electronic levels, thiab high-resolution probes.
Peb ua raws li cov qauv ntawv pov thawj tib lub sijhawm (ISO 9001, 45001, 14001, CE) txhais tau tias txhua yam ntawm kev tsim lub rooj, txij li kev nrhiav cov khoom siv raw mus rau qhov kev ntsuas zaum kawg, yog tswj hwm los ntawm lub kaw lus tswj hwm zoo thoob ntiaj teb. Qib kev lees paub zoo no yog vim li cas peb cov rooj tau txais kev ntseeg siab los ntawm cov koom haum ua thawj coj hauv ntiaj teb thiab cov tuam txhab thoob ntiaj teb.
Kev Sib Koom Tes Ntau Yam: Ntau Tshaj Li Ib Qho Chaw Tiaj
Cov rooj granite metrology niaj hnub nim no tau koom ua ke rau hauv cov tshuab ua haujlwm nyuaj. Lawv tsis yog tsim los ua cov chaw siv xwb tab sis kuj yog cov hauv paus rau cov khoom siv dynamic:
-
Cov Cheebtsam Sib Koom Ua Ke: Cov rooj tuaj yeem ua tau raws li qhov xav tau nrog cov yam ntxwv meej xws li T-slots, cov ntxig xov (piv txwv li, Mahr, M6, M8), thiab cov grooves cua. Cov yam ntxwv no tso cai rau kev teeb tsa ncaj qha, qhov tseeb siab ntawm cov khoom siv tshuab xws li cov lus qhia linear, cov kem optical, thiab cov theem XY dynamic, hloov lub rooj passive mus rau hauv lub hauv paus tshuab nquag.
-
Kev Ruaj Ntseg ntawm Lub Cev: Thaum lub rooj granite raug teeb tsa rau ntawm lub rooj sawv ntsug uas tau tsim tshwj xeeb - feem ntau muaj cov ntaub thaiv kev co lossis cov taw qhia - tag nrho cov khoom sib dhos ua ib qho system metrology ruaj khov heev, qhov tseem ceeb rau kev tswj hwm kev sib phim ntawm ntau-axis CMMs thiab cov cuab yeej ntsuas laser nyuaj.
Nyob rau hauv ib lub caij nyoog uas kev tsim khoom raug txiav txim siab qhov zoo dua ntawm kev sib tw, lub rooj granite metrology tseem yog lub hauv paus tseem ceeb hauv kev ruaj ntseg zoo. Nws ua kom ntseeg tau tias txhua qhov kev ntsuas, txhua qhov khoom sib dhos, thiab txhua daim ntawv qhia zoo tsim tawm, yog raws li qhov chaw siv tau, tsis muaj kev co, tiv thaiv kev ncaj ncees ntawm koj cov txheej txheem ntau lawm.
