Hauv kev lag luam siab-txij li aerospace thiab automotive mus rau lub zog thiab cov tshuab hnyav-qhov kev thov rau qhov tseeb tsis yog vim tias cov khoom loj dua. Ntawm qhov tsis sib xws, cov khoom loj xws li turbine housings, gearbox casings, lossis structural weldments feem ntau nqa cov geometric tolerances nruj dua piv rau lawv qhov loj me, ua rau kev ntsuas txhim khu kev qha tsis yog tsuas yog nyuaj, tab sis tseem ceeb heev. Thiab tseem, ntau lub chaw tsis quav ntsej txog qhov tseem ceeb tshaj plaws hauv kev tshuaj xyuas loj-qhov: qhov ruaj khov thiab tiaj tus ntawm qhov chaw siv. Yog tias koj ua haujlwm nrog lub phaj granite loj, koj twb nkag siab nws tus nqi-tab sis koj puas tau txais kev ua tau zoo tag nrho uas nws muaj peev xwm xa tawm?
Qhov tseeb yog, ibphaj graniteib leeg xwb tsis txaus. Yog tsis muaj kev txhawb nqa zoo, kev tswj hwm ib puag ncig, thiab kev koom ua ke rau hauv cov txheej txheem ntsuas calibrated, txawm tias lub slab qib siab tshaj plaws tuaj yeem ua tsis tau zoo - lossis qhov phem dua, ua rau muaj qhov yuam kev zais. Yog vim li cas cov tuam txhab tsim khoom tsis yog yuav lub phaj xwb; lawv nqis peev rau hauv ib lub kaw lus tiav - tshwj xeeb, qhov tseebgranite nto phajnrog lub rooj sawv ntsug uas tsim los kom ruaj khov, yooj yim siv, thiab ruaj khov mus ntev. Vim tias thaum koj lub phaj poob me ntsis hauv qab nws qhov hnyav lossis co los ntawm cov tshuab ze, txhua qhov ntsuas qhov siab, txhua qhov kev kuaj xyuas qhov sib npaug, thiab txhua qhov sib dhos yuav ua rau muaj kev txhawj xeeb.
Granite tau yog tus qauv kub rau cov nto uas siv tau zoo tshaj plaws rau ntau tshaj 70 xyoo, thiab rau qhov laj thawj zoo ntawm kev tshawb fawb. Nws cov khoom dub zoo nkauj, tsis muaj qhov porous muaj kev ruaj khov zoo kawg nkaus, kev nthuav dav thermal tsawg kawg nkaus (feem ntau yog 6–8 µm ib 'meter' ib °C), thiab kev txo qis kev co ntawm cov khoom siv kho tshuab - txhua yam tseem ceeb thaum txheeb xyuas cov yam ntxwv ntawm ntau lub tuj. Tsis zoo li cov hlau cam khwb cia lossis cov rooj hlau ua, uas warp nrog kev hloov pauv kub, corrode dhau sijhawm, thiab khaws cov kev ntxhov siab sab hauv, granite tseem nyob hauv qab cov xwm txheej ib txwm muaj. Qhov no yog vim li cas cov qauv thoob ntiaj teb xws li ASME B89.3.7 thiab ISO 8512-2 teev granite ua cov khoom siv tsuas yog siv tau rau Qib 00 txog Qib 1 cov phaj nto siv hauv kev ntsuas thiab kev tshuaj xyuas qhov tseeb siab.
Tiam sis qhov loj hloov txhua yam. Ib lub phaj granite loj—piv txwv li, 2000 x 4000 hli lossis loj dua—tuaj yeem hnyav dua 2,000 kilograms. Ntawm qhov hnyav ntawd, nws txoj kev txhawb nqa yuav tseem ceeb npaum li nws qib tiaj tiaj. Kev tsim qauv sawv ntsug tsis raug (piv txwv li, qhov chaw tsis sib npaug ntawm ceg, cov thav duab yooj ywm, lossis tsis txaus bracing) tuaj yeem ua rau muaj kev hloov pauv uas tshaj qhov kev kam rau siab. Piv txwv li, ib lub phaj Qib 0 ntsuas 3000 x 1500 hli yuav tsum tswj qhov tiaj tiaj hauv ± 18 microns thoob plaws nws tag nrho qhov chaw raws li ISO 8512-2. Yog tias lub sawv ntsug tso cai rau txawm tias me ntsis bowing ntawm qhov chaw, qhov spec ntawd raug ua txhaum tam sim ntawd—tsis yog vim granite tsis zoo, tab sis kev tsim kho tsis zoo.
Qhov no yog qhov uas "nrog sawv ntsug" ib feem ntawmprecision granite nto phajnrog lub rooj sawv hloov pauv los ntawm ib qho khoom siv mus rau hauv qhov yuav tsum tau ua tseem ceeb. Lub rooj sawv ntsug uas tsim los rau lub hom phiaj tsis yog ib lub thav duab xwb - nws yog ib lub cev tsim los ntawm kev siv kev tshuaj xyuas cov khoom siv finite los faib cov khoom thauj kom sib npaug, txo qhov resonance, thiab muab kev txhawb nqa peb-taw tes lossis ntau-taw tes ruaj khov uas phim nrog lub phaj cov ntsiab lus ntuj. Cov rooj sawv ntsug zoo tshaj plaws muaj cov taw hloov kho tau, kev co-cais, kev txhawb nqa hla, thiab kev nkag mus rau ergonomic rau cov neeg teb xov tooj thiab cov khoom siv. Qee qhov txawm tias koom ua ke cov kev hauv av los tshem tawm cov hluav taws xob - tseem ceeb hauv cov khoom siv hluav taws xob lossis cov chaw huv.
Ntawm ZHHIMG, peb tau pom thawj zaug tias lub kaw lus zoo hloov pauv cov txiaj ntsig li cas. Ib lub chaw tsim khoom cua turbine hauv North America tau tawm tsam nrog kev ntsuas qhov sib npaug ntawm cov hauv paus nacelle. Lawv lub rooj granite uas twb muaj lawm zaum ntawm lub thav duab hlau uas tau hloov kho dua tshiab uas khoov tau thaum lub sijhawm thauj khoom. Tom qab teeb tsa lub phaj granite loj uas tau ntawv pov thawj uas tau teeb tsa rau ntawm lub rooj sawv ntsug uas tau tsim tshwj xeeb nrog cov taw qhia qib calibrated, lawv qhov kev hloov pauv ntawm cov neeg ua haujlwm tau poob qis 52%, thiab cov neeg siv khoom tsis lees txais tag nrho. Cov cuab yeej tsis tau hloov pauv - tsuas yog lub hauv paus xwb.
Qhov tseem ceeb ib yam li ntawd yog seb cov txheej txheem no sib xyaw ua ke li cas rau hauv cov haujlwm txhua hnub. Lub phaj granite nto uas tsim tau zoo nrog lub rooj sawv ntsug tsa qhov chaw ua haujlwm mus rau qhov siab ergonomic (feem ntau 850–900 hli), txo qhov nkees ntawm tus neeg teb xov tooj thaum lub sijhawm tshuaj xyuas ntev. Nws muab kev nkag mus rau txhua sab rau CMM caj npab, laser trackers, lossis cov cuab yeej siv tes. Thiab vim tias lub rooj sawv ntsug cais cov granite ntawm kev co hauv pem teb - feem ntau nyob ze ntawm cov xovxwm, cov kab stamping, lossis HVAC units - nws khaws cia qhov kev ncaj ncees ntawm cov cim qhia rhiab heev lossis cov tswv qhov siab hluav taws xob.
Kev saib xyuas kuj tseem ceeb heev. Txawm hais tias granite nws tus kheej xav tau kev saib xyuas me ntsis dhau ntawm kev ntxuav tas li nrog isopropyl cawv, lub rooj sawv yuav tsum tau kuaj xyuas tas li rau qhov nruj ntawm lub bolt, qhov sib npaug, thiab kev ruaj khov ntawm cov qauv. Thiab ib yam li lub phaj, tag nrho cov khoom sib dhos yuav tsum tau kuaj xyuas tas li. Kev ntsuas qhov tseeb ntawm lub phaj nto rau cov kab ke loj suav nrog tsis yog tsuas yog kev kos duab tiaj tiaj ntawm granite, tab sis kev ntsuam xyuas ntawm kev ruaj khov ntawm tag nrho lub cev - suav nrog kev hloov pauv ntawm lub rooj sawv hauv qab qhov hnyav simulated.
Thaum xaiv ib lub phaj granite loj, saib dhau qhov ntev thiab tus nqi. Nug txog:
- Daim ntawv pov thawj tag nrho rau ASME B89.3.7 lossis ISO 8512-2, suav nrog daim ntawv qhia contour ntawm qhov sib txawv ntawm qhov tiaj tiaj
- Cov ntaub ntawv pov thawj ntawm keeb kwm granite (cov pob zeb zoo, txo kev ntxhov siab, tsis muaj qhov tawg)
- Cov duab kos ntawm lub rooj sawv ntsug, qhia txog cov qauv geometry thiab cov ntaub ntawv qhia txog cov khoom siv
- Cov ntaub ntawv tshuaj xyuas kev co yog tias ua haujlwm hauv cov chaw ib puag ncig dynamic
Ntawm ZHHIMG, peb koom tes nrog cov chaw ua haujlwm uas kho cov granite loj ua cov platforms metrology sib xyaw ua ke - tsis yog cov khoom lag luam. Txhua lub phaj granite nto nrog lub rooj sawv ntsug uas peb muab yog kuaj ib tus zuj zus hauv qab kev thauj khoom, serialized rau traceability, thiab nrog daim ntawv pov thawj calibration NIST-traceable. Peb tsis ntseeg hauv "ze txaus." Hauv kev ntsuas loj, tsis muaj chaw rau kev sib haum xeeb.
Vim tias thaum koj qhov khoom raug nqi rau tus lej thiab koj cov neeg siv khoom xav tau kev xa khoom uas tsis muaj qhov tsis zoo, koj qhov chaw siv ua piv txwv tsis tuaj yeem yog qhov xav tom qab. Nws yuav tsum yog koj cov khoom muaj nqis tshaj plaws - tus neeg lav qhov tseeb ntsiag to hauv lub ntiaj teb uas microns tseem ceeb.
Yog li ntawd, nug koj tus kheej: koj qhov kev teeb tsa tam sim no puas txhawb nqa koj lub hom phiaj raug - lossis ua rau lawv puas tsuaj ntsiag to? Ntawm ZHHIMG, peb pab koj tsim kev ntseeg siab los ntawm hauv av, nrog cov txheej txheem granite uas xa cov lus tseeb uas koj tuaj yeem ntsuas, ntseeg siab, thiab tiv thaiv.
