Amapulatifomu okunemba kwe-granite ngokwezifiso adlala indima ebalulekile ezimbonini ezidinga ukunemba okukhulu nokuzinza, njengokusebenza ngokunemba, i-metrology, kanye nokuhlanganiswa. Inqubo yokwakha ipulatifomu ngokwezifiso iqala ngokuqonda okuphelele izidingo zamakhasimende. Lokhu kufaka phakathi imininingwane yokusetshenziswa, umthamo womthwalo olindelekile, ubukhulu, kanye nezindinganiso zokunemba. Ukuxhumana okucacile kulesi sigaba kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezidingo zokusebenza kanye nezemvelo.
Uma izidingo sezichaziwe, onjiniyela bakha imidwebo yobuchwepheshe enemininingwane, bechaza ukubekezelelana, ukuthamba kwendawo, kanye nezici zesakhiwo njengezindawo ze-T noma izindawo zokufaka. Amathuluzi okuklama athuthukisiwe avame ukusetshenziswa ukulingisa ukucindezeleka kanye nokuziphatha kokushisa, ukuqinisekisa ukuthi ipulatifomu isebenza ngokwethembeka ngaphansi kwezimo zangempela.
Ngemva kokuba umklamo usuqediwe, ibhulokhi le-granite lifakwa ekucubunguleni okunembile. Ukusika, ukugaya, nokupholisha kwenziwa ngemishini ekhethekile ukuze kufezwe ukuthamba okumangalisayo nokunemba okulinganiselwe. Inqubo yokucubungula ngokucophelela inciphisa ukuguquguquka futhi igcina ubuqotho besakhiwo sepulatifomu.
Yonke ipulatifomu eqediwe ihlolwa ngokucophelela. Ukuthamba, ukulingana, kanye nekhwalithi yobuso kulinganiswa ngokucophelela, futhi noma yikuphi ukuphambuka kuyalungiswa ukuze kuhlangatshezwane nezindinganiso zomhlaba wonke eziqinile. Imibiko yokuhlola eningiliziwe iyanikezwa, okunikeza amakhasimende ukuzethemba ekuthembekeni nasekuqondeni kwepulatifomu yabo.
Okokugcina, ipulatifomu ipakishwe ngokucophelela ukuze ithunyelwe ngokuphephile. Kusukela ekuqinisekisweni kwesidingo sokuqala kuya ekuhlolweni kokugcina, yonke inqubo yenzelwe ukuqinisekisa ukuthi ipulatifomu ngayinye yokunemba kwe-granite eyenziwe ngokwezifiso inikeza ukusebenza okulinganayo nokuqina kwesikhathi eside. Lawa mapulatifomu awawona nje ama-surface azinzile—ayisisekelo sokunemba ekusetshenzisweni kwezimboni okudingakalayo.
