Kumdyarho oqhubekayo osiya kumda we-nanometer, iimfuno ezibekwe ekuchanekeni kwemveliso zikhula ngokukhawuleza. Iinjineli ziyila iinkqubo ezitshintshayo ezinee-sub-micron feedback loops kwaye zisebenzisa izixhobo ezingaqhelekanga, kodwa umlinganiselo wokugqibela womgangatho udla ngokuxhomekeke kwisiseko esilula nesizinzileyo esifumanekayo: i-precision granite.ipleyiti yokulinganisa umphezulu wegranite, edla ngokusebenza njengeGranite Metrology Table, ayisiyonto nje yesixhobo; yindlela ebonakalayo yokubonisa i-zero plane, indawo yokubhekisa engaguqukiyo eqinisekisa zonke ezinye izinto kwinkqubo echanekileyo.
Isisombululo esipheleleyo—esiquka ipleyiti yomphezulu wegranite emnyama echanekileyo ngokwayo, ipleyiti yomphezulu wegranite ekhethekileyo enenkxaso, kunye netafile yokulinganisa yegranite epheleleyo ene-stand—imele incopho yozinzo olungenakulinganiswa. Ezi zixhobo ziintsika apho ingxubakaxaka yokusingqongileyo kokwenziwa kwemveliso ihluzwa khona, ukuqinisekisa ukuba iziphumo zokulinganisa ziyalandeleka kwaye zithembekile.
I-Physics Engaphukiyo yeBlack Precision Granite Surface Plate
Intembeko engagungqiyo ebekwe kwi-granite phezu kwezinto ezizezinye (ezifana nentsimbi okanye ikhonkrithi ye-polymer) isekelwe kwiimpawu ezimbini ezibalulekileyo nezingasebenziyo: uzinzo olukhethekileyo lobushushu kunye nokunciphisa ukungcangcazela okuphezulu.
Uzinzo lobushushu: Inzuzo ephantsi ye-CTE
Kuyo nayiphi na imeko elawulwa yimozulu, ukuguquguquka okuncinci kobushushu akunakuphepheka. Kwizixhobo zesinyithi, oku kungenisa ukungazinzi okukhawulezileyo ngenxa yeCoefficient of Thermal Expansion yazo ephezulu (CTE). Isakhelo sesinyithi sinokutshintsha ii-micrometers ezininzi phezu kokutshintsha okuncinci kobushushu, nto leyo ebeka emngciphekweni ukuchaneka.
Ukuchaneka okumnyamaiipleyiti zomphezulu wegranite, ingakumbi ezo zifunyenwe kwiindawo ezinoxinano olukhulu (ezifana nezinto ze-ZHHIMG ezifikelela kwi-3100 kg/m³), zine-CTE ephantsi kakhulu. Le propati yezinto ezizalwa nazo iqinisekisa ukuba utshintsho lobukhulu bomphezulu wokulinganisa luncitshisiwe, nto leyo enika isalathiso esihlala siyinyani nokuba kukho utshintsho oluqhelekileyo lobushushu obuphakathi. Ngaphezu koko, i-inertia enkulu yobushushu begranite enoxinano olukhulu inceda ukuba imelane ne-gradients yobushushu ekhawulezayo, iqinisekisa ukuba ubushushu obuveliswa zizixhobo zoqhagamshelwano okanye zokulinganisa abuguquli i-geometry yomphezulu.
Ukusebenza Okuncinci: Ukuthulisa Indalo Esingqongileyo
Kwilebhu ye-metrology, ukuchaneka komatshini kufuneka kuhlukaniswe nokungcangcazela komgangatho ongqongileyo. Ulwakhiwo lwekristale yeGranite luyinika amandla aphezulu okudambisa angaphakathi, oko kuthetha ukuba ifunxa amandla oomatshini ngokukhawuleza kwaye iwaguqule abe bubushushu obungenamsebenzi. Xa izixhobo zokulinganisa zeGranite ezinesisombululo esiphezulu zibekwe kwipleyiti, igranite iyayithintela ngokufanelekileyo i-resonance, ithintela ingxolo yokusingqongileyo ekubeni yonakalise imilinganiselo ebuthathaka eyenziwa yi-CMMs, ii-optical profilers, okanye ii-laser interferometers. Le ndawo ithuleyo ye-kinetic ayinakuxoxiswana ngayo xa kuhlolwa i-nanoscale.
Ukusuka kwiSlab ukuya kwiNkqubo: Itafile yokulinganisa iGranite eneStand
Nangona i-granite slab ngokwayo inika uzinzo, itafile yokulinganisa ye-granite ene-stand iguqula umphezulu ongasebenziyo ube sisikhululo se-metrology esisebenza ngokupheleleyo nesidibeneyo. Uyilo lwenkqubo yokuxhasa lubaluleke kakhulu njengezinto zepleyiti.
Ukudityaniswa kwepleyiti yomphezulu wegranite kunye nenkxaso yenzelwe ukugcina ubunyani bejometri obuqinisekisiweyo bepleyiti. Izakhiwo zenkxaso zihlala ziyilelwe ukuba zihambelane ngokuchanekileyo namanqaku e-Airy aqokelelweyo epleyiti okanye amanqaku eBessel, angawona manqaku afanelekileyo enkxaso asasaza uxinzelelo ngokulinganayo kwaye anciphise ukuphambuka kuwo wonke umphezulu. Kwiipleyiti ezinkulu kakhulu okanye ezinzima, kusetyenziswa iinkqubo zenkxaso ezinamanqaku amaninzi antsonkothileyo, zihlala zineenyawo zokulinganisa ezihlengahlengiswayo okanye ii-pad ezihlanganisiweyo zokuzihlukanisa.
Itafile yokulinganisa igranite esemgangathweni ophezulu enesitendi iqinisekisa ukuba ukuthamba kwepleyiti okuqinisekisiweyo kugcinwa phantsi komthwalo. Nakuphi na ukungangqinelani kokuqiniswa kwesitendi okanye ukuchaneka kokulenza inqanaba ngoko nangoko kuthetha ukugqwetheka, okwenza ipleyiti yonke ingabi namsebenzi kumsebenzi ochanekileyo. Ke ngoko, inkqubo yetafile epheleleyo idla ngokuthathwa njengeyunithi enye, ecociweyo kakhulu yeGranite Metrology Table, elinganiswe ngononophelo kwaye iqinisekisiwe kwindawo yayo kwiziko lomthengi.
Inkqubo yeZixhobo zokulinganisa iGranite
Ukusetyenziswa kwepleyiti yomphezulu wokulinganisa igranite kwenziwa ngezixhobo zokulinganisa igranite ezihamba nazo. Ezi zixhobo—izikwere zegranite, imiphetho ethe tye, iibhloko ze-V, kunye nee-parallels—kufuneka zenziwe ngezinto ezifanayo zegranite ezinoxinano oluphezulu ukuqinisekisa ukuhambelana kwezinto kulo lonke ixesha lokulinganisa. Oku kubalulekile ekugcineni ukulingana kobushushu kunye nokuxinana okufanayo kuzo zonke izinto ezibandakanyekayo kwinkqubo yokuhlolwa.
Xa kuhlolwa isikwere sesixhobo esintsonkothileyo, umzekelo, ukufana kwesikwere segranite xa kuthelekiswa nepleyiti, ukuthe tye kwerula yegranite, kunye nokuthe tyaba kwepleyiti yokulinganisa umphezulu wegranite kufuneka zonke zilungelelaniswe ngokugqibeleleyo kwaye ziqinisekiswe. Uzinzo oluhlangeneyo lwezi zixhobo—zonke zisebenzisa iimpawu zezinto eziphezulu zegranite—ziqinisekisa ukuba iimpazamo zejiyometri ezifunyenweyo ngokwenene ziimpazamo kwindawo yokusebenza, kungekhona kwinkqubo yokulinganisa.
Igunya leMigangatho kunye noBugcisa
Ukuveliswa kwepleyiti yomphezulu yegranite emnyama esemgangathweni ogqwesileyo kudlula ukwenziwa nje; kufuna umxube wetekhnoloji ephucukileyo kunye nezakhono zabantu ezingenakulinganiswa.

Ukuthobela iMithetho yeHlabathi: Inkqubo yomgangatho kufuneka iqinisekiswe ngokwemigangatho eyahlukeneyo yehlabathi (ISO 9001, 14001, 45001) kwaye ikwazi ukuqinisekisa iipleyiti ngokwemigangatho eyahlukeneyo, kuquka i-DIN, i-ASME, i-JIS, kunye ne-GB, ukuqinisekisa ukuba iGranite Metrology Table iyahlangabezana neemfuno ezingqongqo kwihlabathi liphela.
Ubude negunya lezi zixhobo zokulinganisa iGranite zibonisa umgaqo osisiseko: kwixesha le-automation eguquguqukayo, inyaniso yejometri kufuneka ihlale ingasebenzi, izinzile, kwaye ilandeleke. Ipleyiti yomphezulu wegranite enenkxaso, esebenza njengeplani yokugqibela ye-zero-reference, ihlala isisiseko esingenakushukunyiswa kuyo yonke inyathelo lobuchwepheshe kubunjineli obuchanekileyo kakhulu.
