Ensimini yokuqinisekisa ikhwalithi ephezulu, i-Coordinate Measuring Machine (CMM) imele njengomlamuli omkhulu weqiniso. Kungakhathaliseki ukuthi iqinisekisa i-geometry eyinkimbinkimbi ye-turbine yezindiza noma imidwebo ebucayi ye-implant yezokwelapha, i-CMM kumele inikeze izilinganiso ezinembile ngaphakathi kwengxenye encane yezinwele zomuntu. Ukuze kufezwe leli zinga lokusebenza, umshini udinga isisekelo esingokoqobo esingavikelekile ekuphazamisekeni kwemvelo. Yingakho i-granite emnyama isibe yinto ekhethwayo yezingxenye zesakhiwo ze-CMM ezisezingeni lomhlaba.
Isisekelo Sokuzinza Okulinganayo
Inselele enkulu yanoma iyiphi i-CMM ukugcina i-geometry yayo ngokuhamba kwesikhathi nangaphansi kwezimo ezihlukahlukene. Izingxenye zensimbi, nakuba ziqinile, zisengozini yokucindezeleka kwangaphakathi kanye nokwanda okukhulu kokushisa. Uma ibhuloho noma isisekelo se-CMM sanda noma sigobeka ngisho nakancane, lonke uhlelo lokuxhumanisa luyaphonswa ekuqondeni.
I-granite emnyama, ikakhulukazi izinhlobo ezixinene kakhulu njenge-ZHHIMG Black Granite, inikeza ikhambi lemvelo. Njengento echithe izigidi zeminyaka ngaphansi komhlaba, ngokwemvelo "iyakhululeka ekucindezelekeni." Ayinayo "inkumbulo" yenqubo yokukhiqiza efana nokukhipha noma ukushisela, okusho ukuthi ngeke ishintshe kancane kancane isimo eminyakeni yokusetshenziswa. Lokhu kuzinza kobukhulu besikhathi eside kuqinisekisa ukuthi i-CMM elinganisiwe namuhla izohlala inembile iminyaka ezayo, inikeze isisekelo esihambisanayo sokukhiqiza kwezimboni.
Ukusebenza Okuphezulu Kokushisa
Izinga lokushisa mhlawumbe liyinguquko enkulu kunazo zonke elebhu ye-metrology. Nakuba amalabhu amaningi elawulwa yisimo sezulu, ukushisa okuvela ezinjinini, kuma-elekthronikhi, ngisho nakumqhubi womuntu kungadala izimo zezulu ezincane ezithinta ukunemba komshini. I-granite emnyama idume nge-coefficient yayo ephansi yokwanda kokushisa. Ngaphezu kwalokho, isisindo sayo esiphezulu sokushisa sisho ukuthi isabela kancane kakhulu ezinguqukweni zokushisa.
Nakuba ingxenye yensimbi ingase isabele ngokushesha emoyeni ofudumele, i-granite isebenza “njengesinki” yokushisa, imunca ukushisa ngaphandle kokushintsha kobukhulu obusheshayo. Lesi sikhathi sokuphendula esisheshayo sivumela isofthiwe yomshini ukuthi ikwazi ukukhokhela kalula ukushintsha kwemvelo, okuholela kudatha ethembekile kakhulu ezimweni zangempela zesitolo. Kubakhiqizi bomhlaba wonke abasebenza ezimweni zezulu ezahlukahlukene, lokhu kungabi namandla okushisa kuyinzuzo ebalulekile evikela ubuqotho benqubo yabo yokulawula ikhwalithi.
Ukudambisa Ukudlidliza kanye Nobunzima
Ukunemba akukhona nje ukuhlala unganyakazi; kumayelana nokumelana nokunyakaza. Ama-CMM avame ukusebenza ezindaweni lapho imishini esindayo, ama-forklift, noma izinhlelo ze-HVAC zidala ukudlidliza phansi okuqhubekayo. Lokhu kudlidliza kungahamba ngohlaka lomshini futhi kubonakale “njengomsindo” kudatha yokulinganisa, okuholela ekwenqatshweni okungamanga noma ukufundwa okungahambisani.
Ubuningi obukhulu be-granite emnyama (ngokuvamile cishe ama-3100 kg/m³) bunikeza isisindo esidingekayo ukuze kugaywe umshini. Okubaluleke kakhulu, i-granite inezici ezinhle kakhulu zokudambisa ngaphakathi. Ngokwemvelo ichitha amandla e-kinetic ngokushesha kakhulu kunensimbi ecijile noma i-aluminium. Lapho i-probe ye-CMM ihamba ngesivinini esikhulu, izingxenye ze-granite ziyasiza ekugwinyeni i-inertia ephumayo, okuvumela umshini ukuthi uhlale ngokushesha futhi uthathe izilinganiso ngokushesha ngaphandle kokulahlekelwa ukunemba.
Ukumelana Nokugqokwa Nokunakekelwa
I-CMM iwutshalomali olukhulu lwemali, futhi ubude bayo buhlobene ngqo nokuqina kwezindawo zayo. Izindlela eziqondisayo ze-CMM—indawo lapho ama-air bearings antanta khona—kumele zihlale ziyisicaba futhi zibushelelezi ngokuphelele. I-granite emnyama iqine kakhulu, ivame ukuba phezulu kunezinsimbi eziningi esikalini sikaMohs. Lobu bunzima buyenza imelane kakhulu nemihuzuko nemihuzuko.
Ngaphezu kwalokho, i-granite emnyama ayisebenzisi magnetic futhi ayihambisi ugesi. Ayidonsi uthuli lwensimbi noma izingcezu ezingaphazamisa ama-probe kagesi abucayi noma ziklwebhe izindlela zokuqondisa. Ngenxa yokuthi ayinawo amakhemikhali, ayigqwali noma ibole uma ivezwa emswakama noma emafutheni avela ezandleni zomqhubi. Lolu hlobo "lokunganakekelwa kahle" luyinzuzo enkulu yokusebenza, kunciphisa isikhathi sokungasebenzi esidingekayo sokuhlanza nokuvuselela umphezulu.
Ukufeza Ukushaya Okunembe Kakhulu
Ukukhiqizwa kwezingxenye ze-granite emnyama kuhilela inqubo eyaziwa ngokuthi i-lapping, lapho itshe ligaywa khona kusetshenziswa izinto zokuzisusa ezicolekile kancane kancane. Ngenxa yesakhiwo se-granite esifanayo sokusanhlamvu, ochwepheshe bangafinyelela ukubekezelelana kokusicaba okungenakwenzeka ukukopisha ngezinsimbi. Isisekelo se-CMM se-granite emnyama singaxhunywa sibe yi-flatness elinganiswe ngamabhande okukhanya, okuhlinzeka ngendiza ecishe iphelele ukuze ama-air bearings ashelele phezu kwawo.
Lokhu kushelela kubalulekile ekunyakazeni "okungenazingxabano" okudingekayo kuma-CMM anamuhla asheshayo. Ama-air bearing adinga igebe eliqhubekayo lama-micron ambalwa kuphela; uma ubuso be-granite bunezinkinga ezincane kakhulu, i-bearing "ingaphahlazeka," okuholela ekulungisweni okubizayo. Ikhono le-granite emnyama lokubamba lezi zimo eziqine kakhulu yisona sizathu esenza ukuthi ihlale iyinkosi engaphikiswana ngezinto ze-metrology.
Isiphetho: Indinganiso Yomhlaba Wonke Yokunemba
Njengoba ukukhiqiza kuqhubekela ekukhiqizweni "okungaphelele", indima ye-CMM iba yinto ebaluleke kakhulu. Ngokukhetha izingxenye ze-granite emnyama, abakhiqizi batshala imali ezingeni eliphakeme kakhulu lokuzinza, ukuqina, kanye nokunemba. Kusukela ekuncipheni kokudlidliza kwemvelo kuya ekumelaneni nokushisa, izinzuzo ze-granite emnyama yizo ezivumela i-metrology yesimanje ukuthi idlule imingcele yalokho okulinganiselwe.
Ezinkampanini ezithengisa izinto kwamanye amazwe emhlabeni jikelele, ukunikeza ama-CMM izisekelo ze-granite emnyama kuwuphawu lwekhwalithi oluqashelwa emhlabeni wonke. Luyinto ekhuluma ulimi olunembile olusetshenziswa emhlabeni wonke, okuqinisekisa ukuthi kungakhathaliseki ukuthi ingxenye ilinganiswa kuphi emhlabeni, iqiniso lihlala liqinile njengetshe elimi kulo.
