Iipleyiti zomphezulu zegranite ezichanekileyo kudala zithathwa njengezona ziseko zithembekileyo kwi-dimensional metrology. Babonelela ngomphezulu ozinzileyo wereferensi yokuhlolwa, ulungelelwaniso, kunye nemilinganiselo ephezulu yokuchaneka kuwo wonke amashishini afana nokuvelisa i-semiconductor, i-aerospace, i-CNC machining, kunye ne-optical metrology. Nangona ukubaluleka kwabo kungathandabuzeki, kukho inkxalabo enye ehlala ivela kwiiforamu zobuchwepheshe kunye nemibuzo yabathengi:ukufuma kuzichaphazela njani iipleyiti zomphezulu wegraniti?Ngaba ukufuma kunokubangela ukuba ilitye lenyengane ligqwetheke okanye liphulukane nokuchaneka kwalo?
Impendulo, ngokophando kunye namashumi eminyaka yamava kwezoshishino, iyaqinisekisa. I-Granite, ngokukodwa i-granite emnyama enoxinano oluphezulu, yimathiriyeli yendalo ezinzile kakhulu eneempawu zehygroscopic ezingahoywanga. Ngokungafaniyo namatye anqabileyo afana ne-marble okanye i-limestone, i-granite yenziwa ngokucotha kwecrystallization ye-magma enzulu ngaphakathi koMhlaba. Le nkqubo iphumela kwisakhiwo esixineneyo kunye ne-porosity ephantsi kakhulu. Ngokwezinto eziphathekayo, oku kuthetha ukuba i-granite ayifunxi amanzi emoyeni, kwaye ayidumba okanye igxumeke kwindawo efumileyo.
Ngapha koko, oku kuxhathisa ukufuma sesinye sezizathu eziphambili zokuba kutheni igranite ithathe indawo yentsimbi etyhidiweyo kwizicelo ezininzi ze-metrology. Apho intsimbi egayiweyo inokugqwala okanye idleke xa ibekwe kwindawo yokufuma ephezulu, igranite ihlala izinzile ngokwekhemikhali. Nakwiindibano zocweyo ezinamaqondo okufuma anxulumeneyo ngaphezulu kwe-90%, iipleyiti zegranite ezichanekileyo zigcina uzinzo kunye nokuthe tyaba kwazo. Iimvavanyo eziqhutywe kwiindawo ezilawulwayo ziqinisekisa ukuba i-flatness ye-granite surface plate ihlala ngaphakathi kokunyamezela kwe-micrometer kungakhathaliseki utshintsho kumswakama we-atmospheric.
Oko kuthethiweyo, ngelixa i-granite ngokwayo ingachatshazelwa kukufuma, indawo yokulinganisa iyonke isabalulekile. Ukujiya kunokwenzeka kwiindibano zocweyo ezingalawulekiyo kakuhle xa amaqondo obushushu ehla ngesiquphe, kwaye nangona igranite ingagqwali, amanzi ajiyileyo asenokushiya ngasemva uthuli okanye ungcoliseko oluphazamisana nomlinganiselo. Izixhobo ezibekwe kwigranite, ezifana neegeyiji zokudayela, amanqanaba e-elektroniki, okanye ukulungelelanisa oomatshini bokulinganisa, bahlala benovelwano ngakumbi kwiimeko zokusingqongileyo kunesiseko segranite ngokwaso. Ngenxa yesi sizathu, iilabhoratri kunye neeworkshops ziyakhuthazwa ukuba zigcine ubushushu obuzinzileyo kunye nolawulo lokufuma kungekhona nje kuphela kwigranite kodwa kunye nezixhobo ezixhomekeke kuyo.
Ukumelana nokufuma okuphezulu kwegranite kubaluleke kakhulu kumashishini apho iimeko zokusingqongileyo kunzima ukulawula. Iilabhu zeSemiconductor, izibonelelo ze-aerospace, kunye neelebhu zophando zihlala zisebenza ngemigangatho engqongqo yokusingqongileyo, kodwa ukuzinza kwegranite kuqinisekisa umaleko owongezelelweyo wokhuseleko. Kwimimandla enemozulu efumileyo ngokwendalo, ukusuka kuMzantsi-mpuma Asia ukuya elunxwemeni lweYurophu, iipleyiti zomphezulu wegranite ziye zangqina ngokungaguqukiyo zithembekile kunezinye.
Kwi-ZHHIMG®, i-granite emnyama ekhethiweyo kwiimveliso ezichanekileyo inika umgangatho omkhulu wokusebenza. Ngoxinano olumalunga ne-3100 kg nge-cubic meter nganye kunye nesantya sokufunxa kwamanzi esingaphantsi kwe-0.1%, inika uzinzo olungenakuthelekiswa nanto. Oku kuqinisekisa ukuba i-flatness kunye nokuchaneka kugcinwa kwixesha elide lokusetyenziswa. Abathengi kwimveliso ye-semiconductor, optics, CNC machining, kunye namaziko e-metrology kazwelonke axhomekeke kwezi propati xa ngokuchanekileyo ngokuchanekileyo kufuneka.
Enye inkalo emele iqwalaselwe kukulondoloza. Nangona i-granite ingachatshazelwa kukufuma, ezona ndlela zilungileyo zinceda ukwandisa ubomi bayo benkonzo. Ukucoca rhoqo ngelaphu elingena-lint kuthintela ukuqokelelwa kothuli. Izigqubuthelo ezikhuselayo zinokugcina imiphezulu ingenawo amasuntswana omoya xa ipleyiti ingasetyenziswa. Ukulinganisa kwexesha kunye nezixhobo eziqinisekisiweyo ziqinisekisa ukuchaneka kwexesha elide, kwaye oku kubaluleke kakhulu kwiindawo ezichanekileyo ezichanekileyo apho ukunyamezela kunokufikelela kwinqanaba elincinci le-micron. Kuzo zonke ezi meko, ukuxhathisa kwe-granite kwindalo kukufuma kwenza umsebenzi ube lula kwaye uqikeleleke ngakumbi kunesinyithi okanye ezinye izinto.
Umbuzo wokufuma kunye neepleyiti ezichanekileyo zegranite zihlala zivela kwinkxalabo yendalo: kubunjineli obuchanekileyo, kunye neyona mpembelelo encinci yendalo inokuba nemiphumo enokulinganiswa. Ubushushu, umzekelo, ngumba obalulekileyo kuzinzo lwe-dimensional. I-coefficient ephantsi yeGranite yokwandiswa kwe-thermal sele iyenza enye yezona zinto zibalaseleyo zokulawula oku kuguquguquka. Xa kufikwa kubumanzi, nangona kunjalo, iinjineli zinokuqiniseka ukuba igranite lolona khetho luthembekileyo olukhoyo.
Kwiinkampani kunye neelabhoratri ezityala imali eninzi kwiziseko zophuhliso lwe-metrology, ukhetho lwezinto eziphathekayo alukho malunga nokusebenza namhlanje kodwa malunga nozinzo kumashumi eminyaka ezayo. I-Granite izibonakalise ukuba iqabane lexesha elide kulo msebenzi. Ukuchasana kwayo nomswakama kuthetha ukuba inokufakwa kwaye isetyenziswe kwiindawo ezininzi ezahlukeneyo, ukusuka kumagumbi ahlambulukileyo ukuya kwiindawo zoshishino ezinzima, ngaphandle kokukhathazeka ukuba umswakama uya kunciphisa ukuchaneka kwayo.
Ukuqukumbela, ukufuma akubeki sisongelo kuzinzo okanye ukuchaneka kweepleyiti zomhlaba wegranite. Ndiyabulela kwindalo yayo exineneyo, engeyiyo i-hygroscopic, i-granite ihlala ingachaphazeleki kukufuma kwaye iyaqhubeka nokubonelela ngereferensi ezinzileyo efunekayo kwi-metrology yanamhlanje. Nangona ulawulo lokusingqongileyo luhlala lubalulekile kwizixhobo kunye nokuchaneka ngokubanzi, i-granite ngokwayo inokuthenjwa ukuxhathisa utshintsho olunxulumene nokufuma. Yiyo loo nto, kuwo onke amashishini nakwihlabathi liphela, igranite ihlala iyimathiriyeli yokuzikhethela kwiziseko zomlinganiselo ochanekileyo.
KwiQela le-ZHONGHUI (ZHHIMG®), olu lwazi alukho nje ithiyori kodwa lubonakaliswe imihla ngemihla ngokubambisana neenkampani ze-Fortune 500, iiyunivesithi eziphambili, kunye namaziko e-metrology kazwelonke. Kwiinjineli ezifuna ukuthembeka kwexesha elide, iipleyiti zomphezulu wegranite azimelanga nje isiko kodwa nekamva lomlinganiselo ochanekileyo.
