Emjahweni oqhubekayo obheke emngceleni we-nanometer, izidingo ezibekwa ekunembileni kokukhiqiza zikhula ngokushesha. Onjiniyela baklama izinhlelo eziguquguqukayo ezinezihibe zempendulo ze-sub-micron futhi basebenzisa izinto ezingavamile, kodwa isilinganiso esiphezulu sekhwalithi sivame ukwehlela esisekelweni esilula nesizinzile kakhulu esitholakalayo: i-precision granite.ipuleti lokulinganisa ubuso begranite, evame ukusebenza njengeThebula le-Granite Metrology, akuyona nje into esetshenziswayo; iyisibonelo esibonakalayo sendiza engu-zero, iphuzu lokubhekisela eliqinile eliqinisekisa zonke ezinye izingxenye ohlelweni olunembe kakhulu.
Isixazululo esiphelele—esihlanganisa ipuleti elimnyama elinobunono begranite uqobo, ipuleti elikhethekile elinobunono begranite elinokusekelwa, kanye netafula lokulinganisa legranite eliphelele elinokuma—limelela ingqikithi yokuzinza okulinganiselwe. Lawa mathuluzi ayinsika lapho kuhlungwa khona isiphithiphithi sendawo yokukhiqiza, okuqinisekisa ukuthi imiphumela yokulinganisa iyalandeleka futhi ithembekile.
I-Fiziksi Engaphukiyo yePlatifomu Yomphezulu weGranite Eqondile Emnyama
Ukuthembela okungaguquki okubekwe ku-granite phezu kwezinto ezihlukile (njengensimbi noma ukhonkolo we-polymer) kusekelwe ezicini ezimbili ezibalulekile nezisebenzayo: ukuzinza kokushisa okungavamile kanye nokunciphisa ukudlidliza okuphezulu.
Ukuzinza Kokushisa: Inzuzo Ephansi Ye-CTE
Kunoma iyiphi indawo elawulwa yisimo sezulu, ukushintshashintsha okuncane kwezinga lokushisa akunakugwenywa. Kumathuluzi ensimbi, lokhu kwethula ukungazinzi okusheshayo ngenxa ye-Coefficient of Thermal Expansion (CTE) yawo ephezulu. Uhlaka lwensimbi lungashukumisa ama-micrometer amaningana phezu kokushintshashintsha okuncane kwezinga lokushisa, okonakalisa ngokushesha ukunemba.
Ukunemba okumnyamaamapuleti ongaphezulu e-granite, ikakhulukazi lezo ezitholakala ezindaweni ezigcwele kakhulu (njengezinto zika-ZHHIMG ezifinyelela ku-3100 kg/m³), zine-CTE ephansi kakhulu. Le mpahla yezinto ezingokwemvelo iqinisekisa ukuthi ushintsho lobukhulu bendawo yokulinganisa luyancipha, okunikeza inkomba ehlala iyiqiniso kungakhathaliseki ukushintshashintsha okuvamile kwezinga lokushisa. Ngaphezu kwalokho, i-inertia enkulu yokushisa ye-granite enobukhulu obuphezulu iyisiza ukuthi imelane nokushintsha okusheshayo kokushisa, okuqinisekisa ukuthi ukushisa okukhiqizwa yimishini yokuxhumana noma yokulinganisa akuguquguquki i-geometry yobuso.
Ukusebenza Kokunciphisa Umswakama: Ukuthulisa Imvelo
Elabhorethri ye-metrology, ukunemba komshini kumele kuhlukaniswe nokudlidliza kwephansi elizungezile. Isakhiwo sekristalu se-Granite siwunika amandla aphezulu okunciphisa umswakama wangaphakathi, okusho ukuthi umunca amandla omshini ngokushesha futhi uwaguqule abe ukushisa okuncane. Lapho Amathuluzi Okulinganisa e-Granite anesinqumo esiphezulu ebekwa epuletini, i-granite icindezela ngempumelelo i-resonance, ivimbele umsindo wezemvelo ukuthi wonakalise izilinganiso ezibucayi ezenziwa yi-CMMs, amaphrofayili optical, noma ama-interferometer e-laser. Le ndawo ethule ye-kinetic ayinakuxoxiswana ngayo ekuhlolweni kwe-nanoscale.
Kusukela ku-Slab kuya ku-System: Ithebula Lokulinganisa le-Granite Eline-Stand
Nakuba i-granite slab ngokwayo inikeza ukuzinza, itafula lokulinganisa le-granite elinesitendi liguqula indawo engasebenzi ibe yisiteshi se-metrology esisebenza ngokugcwele nesihlanganisiwe. Ukwakheka kohlelo lokusekela kubaluleke kakhulu njengezinto zepuleti.
Ukuhlanganiswa kwepuleti lobuso le-granite nokusekelwa kwakhiwe ukuze kugcinwe ubuqotho bejometri obuqinisekisiwe bepuleti. Izakhiwo zokusekela zivame ukuklanywa ukuze zivumelane kahle namaphuzu e-Airy epuleti abaliwe noma amaphuzu e-Bessel, okuyizindawo zokusekela ezifanele kakhulu ezisabalalisa ukucindezeleka ngokulinganayo futhi zinciphise ukuphambuka kulo lonke ubuso. Kumapuleti amakhulu kakhulu noma asindayo, kusetshenziswa izinhlelo zokusekela ezinamaphoyinti amaningi eziyinkimbinkimbi, ngokuvamile ezinezinyawo zokulinganisa ezilungisekayo noma ama-pad okuzihlukanisa okuhlanganisiwe.
Itafula lokulinganisa le-granite elisezingeni eliphezulu elinesitendi liqinisekisa ukuthi ukuthamba kwepuleti okuqinisekisiwe kugcinwa ngaphansi komthwalo. Noma yikuphi ukuyekethisa ekuqineni kwesitendi noma ekuqondeni kokulinganisa kuholela ekuphazamisekeni ngokushesha, okwenza lonke ipuleti lingabi usizo emsebenzini onembile kakhulu. Ngakho-ke, uhlelo lwetafula oluphelele luvame ukubhekwa njengeyunithi eyodwa, ehlanjululwe kakhulu ye-Granite Metrology Table, elinganiswe kahle futhi iqinisekiswe endaweni esendaweni yeklayenti.
I-Ecosystem Yamathuluzi Okulinganisa I-Granite
Ukusetshenziswa kwepuleti lokulinganisa i-granite surface kufezwa ngamathuluzi okulinganisa i-Granite ahambisana nawo. Lezi zesekeli—izikwele ze-granite, imiphetho eqondile, amabhlogo e-V, kanye nokufana—kumele zenziwe ngezinto ezifanayo ze-granite ezinesisindo esiphezulu ukuqinisekisa ukulingana kwezinto kulo lonke ukusetha kokulinganisa. Lokhu kubalulekile ekugcineni ukulingana kokushisa kanye nokunciphisa ukudlidliza okufanayo kuzo zonke izinto ezihilelekile enkambisweni yokuhlola.
Uma kuhlolwa ubunjalo besikwele bento eyinkimbinkimbi, isibonelo, ukufana kwesikwele segranite uma kuqhathaniswa nepuleti, ukuqondile kwerula legranite, kanye nobunjalo besikwele somphezulu wokulinganisa igranite kumele kuhambisane kahle futhi kuqinisekiswe. Ukuqina kwala mathuluzi—wonke asebenzisa izakhiwo zezinto zegranite eziphakeme—kuqinisekisa ukuthi amaphutha ejiyometri atholakele empeleni angamaphutha emsebenzini, hhayi ohlelweni lokulinganisa.
Igunya Lezinga Nobuciko
Ukukhiqizwa kwepuleti elimnyama elinokunemba okuphezulu lomhlaba kudlula ukukhiqizwa nje; kudinga inhlanganisela yobuchwepheshe obuthuthukisiwe kanye nekhono lomuntu elingenakulinganiswa.
-
Umthamo Omkhulu: Abahlinzeki abaphambili kumele babe nengqalasizinda yokuphatha amapuleti okumetha amakhulu kunawo wonke emhlabeni, adinga imishini ekhethekile ye-CNC ekwazi ukuphatha izingxenye ezingaphezu kwamathani ayi-100 kanye nobude bokugoqa obungama-20m.
-
Ukunemba Okuqinisekisiwe: Ukuthamba kokugcina kufezwa ngenqubo enzima yokugoqa ngesandla, eyenziwa yizingcweti ezinolwazi oluningi lweminyaka eminingi. Ikhono lazo lokufinyelela iBanga 00 noma iBanga A lokuthamba, elilinganiswa ngamaqhezu e-micron noma ama-nanometer, liqinisekiswa kusetshenziswa amathuluzi ayinkimbinkimbi njenge-laser interferometers, konke okulandelelwa ngokwezindinganiso zomhlaba wonke (i-NIST, i-PTB, i-NPL).
-
Ukuthobela Umthetho Komhlaba Wonke: Uhlelo lwekhwalithi kumele luqinisekiswe ngokwezindinganiso eziningi zomhlaba wonke (ISO 9001, 14001, 45001) futhi lukwazi ukuqinisekisa amapuleti ngokwezindinganiso ezahlukene zobukhulu, okuhlanganisa i-DIN, i-ASME, i-JIS, kanye ne-GB, ukuqinisekisa ukuthi i-Granite Metrology Table ihlangabezana nezidingo eziqinile kakhulu emhlabeni jikelele.
Ukuphila isikhathi eside negunya lala mathuluzi okulinganisa i-Granite kubonisa isimiso esiyisisekelo: esikhathini sokuzenzakalela okuguquguqukayo, iqiniso lejiyometri kumele lihlale lingasebenzi, lizinzile, futhi lingalandeleka. Ipuleti lobuso le-granite elinokusekelwa, elisebenza njengendiza yokugcina eyi-zero-reference, lihlala liyisisekelo esingenakunyakaziswa salo lonke igxathu lobuchwepheshe kubunjiniyela obunembile kakhulu.
