Ezweni lanamuhla lokukhiqiza ngokunemba okukhulu, lapho ukunemba kulinganiswa ngama-micron ngisho nama-nanometer, ukudlidliza okuncane kakhulu noma ukushintsha kokushisa kunganquma impumelelo noma ukwehluleka. Njengoba izimboni ziqhubeka nokucindezela imingcele yokulinganisa kanye nomshini wokugaya, isidingo sobuso obuqinile, obuthembekile, nobuhlala isikhathi eside asikaze sibe sikhulu kangaka. Yilapho amapulatifomu e-granite aqondile ahluka khona - azalwa izigidi zeminyaka yokwakheka kwemvelo yemvelo futhi aklanywa ngezinqubo zanamuhla zokunemba, abe yisilinganiso esingenakuphikiswa sokunemba kokulinganisa.
Izinzuzo zegranite ziqala ngaphakathi etsheni ngokwalo. Izinto ezisezingeni eliphezulu njenge-ZHHIMG® Black Granite noma iJinan Green Granite zikhethwa ngenxa yesakhiwo sazo esiminyene, okusanhlamvu okufanayo, kanye nokulingana okuhle kakhulu. Lawa matshe adlula ekugugeni kwemvelo ukuze akhulule ukucindezeleka kwangaphakathi okuqongelelwe ngokuhamba kwesikhathi. Ngenxa yalokho, igranite inikeza ukwanda kokushisa okuphansi kakhulu—ngokuvamile okungu-0.5 kuya ku-1.2 × 10⁻⁶/°C—okuyingxenye eyodwa kwezintathu noma ngaphansi kwalokho kwensimbi ephonswe. Leli zinga eliphansi lokukhula lisho ukuthi igranite cishe ayithinteki yizinguquko zokushisa, igcina ukuzinza kobukhulu besikhathi eside futhi iqinisekisa ukunemba kokulinganisa okuqhubekayo ngisho nasezimweni ze-workshop ezishintshashintshayo.
Esinye isici esichazayo samapulatifomu e-granite anembile ukudambisa kwawo ukudlidliza okungavamile. Isakhiwo esincane se-granite esicwebezelayo simunca futhi sihlakaze ukudlidliza kangcono kakhulu kunezinto zensimbi—kuze kube yimpumelelo ephindwe kayishumi kunensimbi ephonswe ngensimbi. Lesi sici sibaluleke kakhulu ezindaweni ezithembele kumathuluzi anesinqumo esiphezulu njenge-interferometers, imishini yokulinganisa ehlanganisiwe (ama-CMM), kanye nezinhlelo zokulinganisa ezibonakalayo. Ngokunciphisa ukudlidliza kanye nokuzwakala, i-granite idala indawo yokulinganisa "ethule" lapho idatha ihlala ihlanzekile futhi ingaphindeka.
I-Granite iphinde inikeze ubulukhuni obungenakuqhathaniswa, ukumelana nokuguguleka, kanye nokumelana nokugqwala. Imelana nokuklwebheka kanye nokugqwala kwamakhemikhali, igcina ukuqina kwayo amashumi eminyaka ngaphansi kokusetshenziswa okuvamile, futhi ayidingi ukunakekelwa—ngokungafani nezindawo zensimbi ezibunjiwe, okumele ziklwejwe njalo futhi ziphathwe ngokugqwala. Ngaphezu kwalokho, i-granite ngokwemvelo ayinamandla kagesi, okwenza ifaneleke kakhulu kuma-laboratories nasezindaweni ezizwela ukuphazamiseka kwamandla kagesi, njengezikhungo ze-MRI noma imishini yokuhlola ngokunemba.
Lezi zici zenza amapulatifomu e-precision granite abe yinto ebalulekile kuzo zonke izimboni ezithembele ekunembeni nasekuzinzeni. Asebenza njengesisekelo semishini yokulinganisa ehambisanayo, ama-laser interferometers, ama-optical comparator, kanye nabahloli be-roundness abasetshenziswa yizikhungo zikazwelonke ze-metrology kanye nama-laboratory ocwaningo athuthukile. Embonini ye-semiconductor, asekela izinhlelo zokuhlola i-wafer kanye nemishini ye-lithography lapho ukuzinza kuthinta ngqo isivuno se-chip. Ekusebenzeni ngokunemba kanye ne-optics, izisekelo ze-granite zinikeza ukwesekwa okuqhubekayo kwemishini yokugaya nokugaya enembile kakhulu, okuqinisekisa ukuqedwa okuphezulu kobuso kanye nobuqotho obunobukhulu. Ngisho nasocwaningweni lwesayensi, kusukela ekutholakaleni kwamagagasi adonsela phansi kuya ekusetshenzisweni kwezinsimbi ze-biomedical, i-granite isebenza njengesisekelo esithembekile esigcina ukuhlolwa kuzinzile futhi kunembile.
Ukukhetha ipulatifomu ye-granite enembile efanelekile kuhilela okungaphezu kokukhetha usayizi noma intengo efanele. Izici ezifana nekhwalithi yezinto ezibonakalayo, ukwakheka kwesakhiwo, kanye nobuciko bokukhiqiza kunquma ukusebenza kwesikhathi eside. Amapulatifomu kufanele ahlangabezane namazinga okunemba aqashelwayo (00, 0, noma 1) ngokuhambisana nezindinganiso ze-ISO noma ze-metrology zikazwelonke, futhi abakhiqizi kufanele bakwazi ukunikeza izitifiketi zokuhlola ezivela eceleni. Amasu athuthukile njengokufaka ngokunemba, ukuguga kwemvelo, kanye nomklamo wokusekela isakhiwo onama-ribbed ngokucophelela kusiza ukuqinisekisa ukuthi ipulatifomu igcina ukuguquguquka okuncane ngaphansi komthwalo.
Uma kuqhathaniswa nezisekelo zensimbi ezibunjiwe zendabuko, i-granite iphumelela kakhulu. Ibonisa ukuzinza okuphezulu, ukumanzisa okungcono, ukumelana nokuguguleka okuphezulu, kanye nezindleko zokulungisa eziphansi, kuyilapho ivikela ukugqwala ngokwemvelo futhi ingathathi hlangothi kumagnetic. Nakuba izindleko zokuqala ze-granite zingase zibe phezulu, isikhathi sayo eside sokuphila kanye nokunemba okuqhubekayo kwenza kube utshalomali olungabizi kakhulu noluthembekile esikhathini eside.
Empeleni, ipulatifomu yegranite enembile akuyona nje ingcezu yetshe—iyisisekelo esithule sokulinganisa nokukhiqiza kwesimanje. Ibonisa ukuzibophezela kwenkampani ekuqondeni, ukuhambisana, kanye nokugqwesa kwekhwalithi. Njengoba izimboni ziqhubekela phambili emazingeni aphezulu okunemba, ukukhetha ipulatifomu yegranite kuwukutshalwa kwezimali hhayi kuphela emishinini kodwa nasesikhathini esizayo sokuthembeka kokulinganisa uqobo.
