Taug kev mus rau hauv txhua lub khw muag tshuab siab, chaw kuaj ntsuas, lossis chaw sib dhos khoom siv dav hlau thoob plaws Tebchaws Europe lossis North America, thiab koj yuav pom ib qho pom zoo: ib daim granite tsaus nti, ci ntsa iab ua lub hauv paus ntsiag to rau kev ntsuas tseem ceeb. Qhov no yog Granite Surface Plate - lub hauv paus ntawm kev ntsuas rau ntau tshaj ib nrab xyoo pua. Tab sis ntawm no yog ib lo lus nug uas ob peb tus neeg nug: puas yog daim phaj ntawd xa qhov tseeb uas nws tau tsim los, lossis nws qhov kev ua tau zoo puas raug cuam tshuam los ntawm nws txoj kev teeb tsa, kev txhawb nqa, thiab kev saib xyuas?
Qhov tseeb yog, ibGranite Nto Phajtsis yog tsuas yog ib daim pob zeb tiaj tiaj xwb. Nws yog ib yam khoom siv uas tau calibrated lawm—ib qho piv txwv ntawm qhov tseeb geometric. Txawm li cas los xij, muaj ntau tus neeg siv nws zoo li rooj tog: bolted rau ntawm lub thav duab flimsy, muab tso ze ntawm qhov chaw cua sov, lossis tso tseg tsis calibrated rau ntau xyoo nyob rau hauv qhov kev xav tias "granite tsis hloov." Txawm hais tias nws yog qhov tseeb tias granite muaj kev ruaj khov tshwj xeeb piv rau cov hlau, nws tsis yog tiv thaiv kev ua yuam kev. Thiab thaum ua ke nrog cov cuab yeej rhiab heev xws li qhov siab gauges, dial indicators, lossis optical comparators, txawm tias qhov sib txawv 10-micron tuaj yeem ua rau muaj kev txiav txim siab tsis raug nqi kim.
Qhov no yog qhov uas qhov sib txawv ntawm lub phaj liab qab thiab lub kaw lus tiav los ua qhov tseem ceeb. Lub Phaj Granite Surface nrog lub rooj sawv tsis yog tsuas yog hais txog kev yooj yim xwb - nws yog hais txog kev ncaj ncees ntawm kev ntsuas. Lub rooj sawv tsis yog ib qho khoom siv; nws yog ib qho khoom siv uas ua kom lub phaj tseem tiaj tus, ruaj khov, thiab nkag tau yooj yim hauv qab lub ntiaj teb tiag tiag. Yog tsis muaj nws, txawm tias cov granite qib siab tshaj plaws tuaj yeem sag, co, lossis hloov - ua rau txhua qhov kev ntsuas uas tau ua rau nws.
Cia peb pib nrog cov khoom siv nws tus kheej. Cov pob zeb granite dub qib Metrology—feem ntau yog los ntawm cov pob zeb zoo, txo kev ntxhov siab hauv Is Nrias teb, Tuam Tshoj, lossis Scandinavia—yog xaiv rau nws cov qauv isotropic, kev nthuav dav thermal qis (kwv yees li 6–8 µm/m·°C), thiab cov khoom damping ntuj. Tsis zoo li cov hlau cam khwb cia, uas xeb, khaws cov kev ntxhov siab machining, thiab nthuav dav pom tseeb nrog qhov kub, granite tseem nyob ruaj khov thoob plaws cov chaw ua haujlwm ib txwm muaj. Yog vim li cas cov qauv thoob ntiaj teb xws li ASME B89.3.7 (Tebchaws Meskas) thiab ISO 8512-2 (thoob ntiaj teb) qhia txog granite ua cov khoom siv tsuas yog siv tau rau cov phaj nto precision siv hauv kev ntsuas thiab kev tshuaj xyuas.
Tab sis cov khoom siv ib leeg tsis txaus. Xav txog qhov no: tus qauv 1000 x 2000 mm Granite Surface Plate hnyav kwv yees li 600–700 kg. Yog tias muab tso rau hauv pem teb tsis sib npaug lossis lub thav duab tsis khov kho, lub ntiajteb txawj nqus ib leeg tuaj yeem ua rau muaj kev cuam tshuam me me - tshwj xeeb tshaj yog nyob rau hauv nruab nrab. Cov kev cuam tshuam no yuav tsis pom rau lub qhov muag tab sis ntsuas tau nrog interferometry, thiab lawv ncaj qha ua txhaum qhov kev kam rau siab. Piv txwv li, lub phaj Qib 0 ntawm qhov loj me ntawd yuav tsum tswj qhov tiaj tus hauv ± 13 microns thoob plaws nws qhov chaw tag nrho ib qho ISO 8512-2. Lub phaj tsis txhawb nqa zoo yuav yooj yim tshaj qhov ntawd - txawm tias lub granite nws tus kheej tau lapped zoo meej.
Qhov ntawd yog lub hwj chim - thiab qhov tsim nyog - ntawm lub hom phiaj tsimGranite Nto Phajnrog lub rooj sawv ntsug. Lub rooj sawv ntsug zoo ua ntau yam ntxiv rau kev tsa lub phaj kom siab ergonomic (feem ntau yog 850–900 hli). Nws muab kev txhawb nqa peb-taw tes lossis ntau-taw tes uas tau xam meej meej sib phim nrog cov ntsiab lus ntuj ntawm lub phaj kom tiv thaiv kev khoov. Nws suav nrog kev sib txuas ruaj khov kom tiv taus torsion. Ntau yam suav nrog cov taw kev co-damping lossis cov chaw sib cais los tiv thaiv kev cuam tshuam hauv pem teb los ntawm cov tshuab nyob ze. Qee qhov txawm tias muaj cov chaw txuas av los tshem tawm cov hluav taws xob - tseem ceeb hauv cov khoom siv hluav taws xob lossis cov ntawv thov chav huv.
Ntawm ZHHIMG, peb tau ua haujlwm nrog cov neeg siv khoom uas xav tias lawv lub phaj granite "zoo txaus" vim tias nws zoo li du thiab tsis tawg. Ib tus neeg muag khoom tsheb hauv Midwest pom tias cov ntawv nyeem sib dhos tsis sib xws ntawm cov kis. Tom qab kev tshawb nrhiav, tus neeg ua txhaum tsis yog CMM lossis tus neeg teb xov tooj - nws yog lub thav duab hlau ua hauv tsev uas khoov thaum lub sijhawm thauj khoom. Hloov mus rau Granite Surface Plate uas tau ntawv pov thawj nrog lub rooj sawv ntsug, tsim los ntawm ASME cov lus qhia, tshem tawm qhov sib txawv ib hmos. Lawv cov nqi pov tseg poob qis 30%, thiab cov lus tsis txaus siab ntawm cov neeg siv khoom ploj mus.
Lwm qhov kev saib tsis taus uas feem ntau pom yog kev kho kom raug. Lub Phaj Nto Granite—txawm tias nws nyob ib leeg lossis ntsia—yuav tsum tau kho dua tshiab tas li kom ntseeg tau. Cov qauv pom zoo kom kho dua tshiab txhua xyoo rau cov phaj uas siv tas li, txawm hais tias cov chaw kuaj mob siab yuav ua nws txhua rau lub hlis. Kev kho kom raug tiag tiag tsis yog daim ntawv cim roj hmab; nws cuam tshuam nrog kev kos duab ntau pua lub ntsiab lus hla qhov chaw siv cov theem hluav taws xob, autocollimators, lossis laser interferometers, tom qab ntawd tsim daim ntawv qhia contour uas qhia txog qhov sib txawv ntawm qhov siab tshaj plaws mus rau hav. Cov ntaub ntawv no yog qhov tseem ceeb rau kev ua raws li ISO/IEC 17025 thiab kev npaj txhij rau kev kuaj xyuas.
Kev saib xyuas kuj tseem ceeb heev. Txawm hais tias granite tsis tas yuav siv roj los yog cov tshuaj pleev tshwj xeeb, nws yuav tsum tau ntxuav tas li nrog isopropyl cawv kom tshem tawm cov dej txias seem, cov hlau tawg, lossis cov hmoov av uas tuaj yeem nkag mus rau hauv cov qhov me me. Tsis txhob muab cov cuab yeej hnyav ncaj qha rau ntawm qhov chaw yam tsis muaj cov ntaub thaiv, thiab tsis txhob rub cov gage blocks - ib txwm tsa thiab tso lawv. Khaws lub phaj npog thaum tsis siv kom tiv thaiv cov pa phem hauv huab cua.
Thaum xaiv Granite Surface Plate, saib ntau tshaj qhov zoo nkauj. Xyuas kom tseeb tias:
- Qib tiaj tiaj (Qib 00 rau cov chaw kuaj ntsuas, Qib 0 rau kev tshuaj xyuas, Qib 1 rau kev siv dav dav)
- Daim ntawv pov thawj rau ASME B89.3.7 lossis ISO 8512-2
- Daim ntawv qhia txog qhov tiaj tiaj uas qhia meej—tsis yog tsuas yog daim ntawv qhia tias dhau/tsis dhau xwb
- Keeb kwm thiab zoo ntawm cov granite (cov nplej zoo, tsis muaj qhov tawg lossis cov leeg quartz)
Thiab tsis txhob saib tsis taus lub rooj sawv ntsug. Nug koj tus neeg muag khoom seb nws puas tau tsim los ntawm kev siv kev tshuaj xyuas cov qauv, seb puas muaj cov taw qhia leveling, thiab seb tag nrho cov kev sib dhos puas tau sim hauv qab kev thauj khoom. Ntawm ZHHIMG, txhua lub Granite Surface Plate nrog lub rooj sawv ntsug uas peb xa khoom yog serialized, lees paub tus kheej, thiab nrog daim ntawv pov thawj NIST-traceable. Peb tsis muag slabs - peb xa cov txheej txheem metrology.
Vim tias thaum kawg, qhov tseeb tsis yog hais txog kev muaj cov cuab yeej kim tshaj plaws. Nws yog hais txog kev muaj lub hauv paus uas koj ntseeg siab tau. Txawm koj tab tom tshuaj xyuas lub hniav turbine, teeb tsa lub pwm, lossis kho cov ntsuas qhov siab, koj cov ntaub ntawv pib nrog qhov chaw hauv qab nws. Yog tias qhov chaw ntawd tsis tiaj tus, ruaj khov, thiab taug qab tau, txhua yam uas ua rau nws yog qhov tsis ntseeg.
Yog li ntawd, nug koj tus kheej: thaum koj ntsuas koj qhov kev ntsuas tseem ceeb tshaj plaws hnub no, koj puas ntseeg siab rau koj qhov kev siv - lossis koj puas cia siab tias nws tseem raug? Ntawm ZHHIMG, peb ntseeg tias kev cia siab tsis yog lub tswv yim ntsuas. Peb pab koj hloov qhov tsis paub tseeb nrog kev ua tau zoo uas tau txheeb xyuas - vim tias qhov tseeb pib los ntawm hauv av mus rau saum.
