Kwihlabathi lanamhlanje lokuvelisa izinto ngendlela echanekileyo, apho ukuchaneka kulinganiswa kwii-microns nakwii-nanometers, ukungcangcazela okuncinci okanye utshintsho lobushushu kunokumisela impumelelo okanye ukungaphumeleli. Njengoko amashishini eqhubeka nokuqhubela phambili imida yokulinganisa kunye noomatshini, imfuno yomphezulu ongqinisisekayo ozinzileyo, othembekileyo, nohlala ixesha elide ayizange ibe nkulu kangako. Kulapho amaqonga e-precision granite ahluke khona - azalwa zizigidi zeminyaka yokwakheka kwendalo yejoloji kwaye akhiwe ngeenkqubo zanamhlanje zokuchaneka, abe luphawu olungenakuphikiswa lokuchaneka kokulinganisa.
Iingenelo zegranite ziqala nzulu ngaphakathi kwelitye ngokwalo. Izinto ezisemgangathweni ophezulu ezifana ne-ZHHIMG® Black Granite okanye iJinan Green Granite zikhethwa ngenxa yesakhiwo sazo esixineneyo, iinkozo ezifanayo, kunye nokuhambelana okuhle kakhulu. La matye adlula ekugugeni kwendalo ukuze akhuphe uxinzelelo lwangaphakathi oluqokelelene ngexesha lejoloji. Ngenxa yoko, igranite inika ukwanda okuphantsi kakhulu kobushushu—ngesiqhelo yi-0.5 ukuya kwi-1.2 × 10⁻⁶/°C—okuyi-1/3 okanye ngaphantsi kweyesinyithi esityhidiweyo. Eli zinga liphantsi lokwanda lithetha ukuba igranite ayichaphazeleki phantse kukutshintsha kobushushu, igcina uzinzo lwexesha elide kwaye iqinisekisa ukuchaneka kokulinganisa okulinganayo nakwiimeko zeworkshop ezitshintshatshintshayo.
Olunye uphawu olucacileyo lwamaqonga e-precision granite kukuxinana kwawo okumangalisayo kokungcangcazela. Isakhiwo se-crystalline microstructure se-granite sifunxa kwaye sichitha ukungcangcazela ngcono kakhulu kunezixhobo zesinyithi—ukuya kuthi ga kwishumi ngempumelelo kune-cast iron. Olu phawu lubaluleke kakhulu kwiindawo ezixhomekeke kwizixhobo ezinesisombululo esiphezulu ezifana nee-interferometers, oomatshini bokulinganisa abadibeneyo (ii-CMM), kunye neenkqubo zokulinganisa ezibonakalayo. Ngokunciphisa ukungcangcazela kunye nokuqaqamba, i-granite idala indawo yokulinganisa "ezolileyo" apho idatha ihlala icocekile kwaye iphindaphindwa.
I-granite ikwanika ubulukhuni obungenakuthelekiswa nanto, ukumelana nokuguguleka, kunye nokumelana nokugqwala. Iyamelana nemikrwelo kunye nokugqwala kweekhemikhali, igcina ubuthe tyaba bayo amashumi eminyaka phantsi kokusetyenziswa okuqhelekileyo, kwaye ayifuni kugcinwa—ngokungafaniyo nemiphezulu yesinyithi esityhidiweyo, ekufuneka ikhuhlwe rhoqo kwaye iphathwe nxamnye nokugqwala. Ngaphezu koko, i-granite ngokwemvelo ayinamagnethi, nto leyo eyenza ukuba ifaneleke kwiilabhoratri nakwiindawo ezibuthathaka kukuphazamiseka kwemagnethi, njengezixhobo ze-MRI okanye izixhobo zokuvavanya ngokuchanekileyo.
Ezi mpawu zenza amaqonga egranite echanekileyo abe yimfuneko kumashishini axhomekeke ekuchanekeni nasekuzinzeni. Asebenza njengesiseko soomatshini bokulinganisa abalungelelanisiweyo, ii-interferometer ze-laser, ii-optical comparators, kunye nabavavanyi be-roundness abasetyenziswa zizikhungo ze-metrology zesizwe kunye neelabhoratri zophando eziphambili. Kwishishini le-semiconductor, baxhasa iinkqubo zokuhlola i-wafer kunye noomatshini be-lithography apho uzinzo luchaphazela ngokuthe ngqo i-chip yield. Kwi-precision machining kunye ne-optics, iziseko zegranite zibonelela ngenkxaso eqhubekayo yoomatshini bokugaya kunye nokugaya ngokuchanekileyo, ukuqinisekisa ukugqitywa okuphezulu komphezulu kunye nokuthembeka kobukhulu. Kwanakwiphando lwesayensi, ukusuka ekufumaneni amaza adonsela phantsi ukuya kwizixhobo ze-biomedical, igranite isebenza njengesiseko esithembekileyo esigcina iimvavanyo zizinzile kwaye zichanekile.
Ukukhetha iqonga legranite elichanekileyo elichanekileyo kubandakanya okungaphezulu kokukhetha ubungakanani okanye ixabiso elifanelekileyo. Izinto ezinje ngomgangatho wezinto, uyilo lwesakhiwo, kunye nobugcisa bokuvelisa zimisela ukusebenza kwexesha elide. Amaqonga kufuneka ahlangabezane namanqanaba okuchaneka aziwayo (00, 0, okanye 1) ngokuhambelana nemigangatho ye-ISO okanye yesizwe ye-metrology, kwaye abavelisi kufuneka bakwazi ukubonelela ngeziqinisekiso zokuhlola zomntu wesithathu. Iindlela eziphambili ezifana nokulepha ngokuchanekileyo, ukuguga kwendalo, kunye noyilo olucokisekileyo lwenkxaso yesakhiwo kunceda ukuqinisekisa ukuba iqonga ligcina ukuguquguquka okuncinci phantsi komthwalo.
Xa ithelekiswa neziseko zesinyithi zemveli, igranite ibalasele ngokucacileyo. Ibonisa uzinzo oluphezulu, ukufuma okungcono, ukumelana nokuguguleka okuphezulu, kunye neendleko zokulungisa eziphantsi, ngelixa ingenamhlwa kwaye ingathathi cala kwimagnethi. Nangona ixabiso lokuqala legranite linokuba phezulu, ixesha layo elide kunye nokuchaneka okuzinzileyo kwenza ukuba ibe lutyalo-mali olungabizi kakhulu noluthembekileyo kwixesha elide.
Ngokwenyani, iqonga legranite elichanekileyo alilolitye nje—lisisiseko esithuleyo sokulinganisa nokuvelisa izinto zanamhlanje. Libonisa ukuzinikela kwenkampani ekuchanekeni, ukuhambelana, kunye nokugqwesa komgangatho. Njengoko amashishini esiya kwimigangatho ephezulu yokuchaneka, ukukhetha iqonga legranite kutyalo-mali kungekuphela nje kwizixhobo kodwa nakwixesha elizayo lokuthembeka kokulinganisa ngokwalo.
