Izikhokelo zegranite ezimnyama, imathiriyeli ekumgangatho ophezulu esetyenziswa ekwakhiweni nasekuphuhliseni imveliso kunye nezixhobo zokulinganisa, zineendawo zosetyenziso eziguquguqukayo.
Okokuqala, izikhokelo zegranite ezimnyama zisetyenziswa koomatshini abafana nokulungelelanisa oomatshini bokulinganisa (i-CMM), oomatshini bokuhlola, kunye nezixhobo zoomatshini ukuxhasa nokukhokela iindawo zabo ezihambayo.Izikhokelo zakhiwe ngobunzima obukhethekileyo, ukubonelela ngokunyakaza okuchanekileyo kunye nokunciphisa iimpazamo ezinokuthi zibe khona kwimilinganiselo, zibenze ziyimfuneko kumatshini ochanekileyo.
Okwesibini, izikhokelo zegranite ezimnyama zisetyenziswa kakhulu kwi-semiconductors kunye neshishini lombane.Izikhokelo zisetyenziselwa ukwenziwa kwee-microelectronics njengoko zibonelela ngomphezulu ozinzile, othe tyaba ukuze kuveliswe kwaye kuhlolwe iindawo ezincinci zombane.Kwakhona, ukuzinza kwe-thermal ye-granite emnyama ibalulekile kuzinzo kunye nokuthembeka kwezixhobo ze-microelectronic eziveliswayo.
Indawo yesithathu yokusetyenziswa kwezikhokelo zegranite emnyama ikwimveliso ye-optics, apho isetyenziselwa ukwenza iitafile ezingaphezulu zezixhobo zokulinganisa ukukhanya.Imiphezulu ye-granite emnyama ine-coefficient ephantsi yokwandiswa kwe-thermal (CTE), inika uzinzo oluhle kakhulu lwe-thermal kwizixhobo zokulinganisa ezisetyenziswa kule ndawo.
Kwimizi-mveliso ye-aerospace kunye nokukhusela, izikhokelo ze-granite ezimnyama zisetyenziswa njengesiseko sokulungiswa kwezixhobo zokuvavanya, ukubonelela ngeqonga elizinzile elikhethekileyo kunye nesicaba sokuvavanya ngokuchanekileyo.Izikhokelo zikwabonelela ngamandla okumelana nokunxiba, okuluncedo kwimizi-mveliso ye-aerospace kunye nokukhusela, ukuqinisekisa ukuqina kwesixhobo.
Ngaphaya koko, izikhokelo zegranite emnyama zisetyenziswa kakhulu kushishino lwenyukliya, apho zisetyenziselwa ukwenza nokuhlola imathiriyeli yokusasazeka ngemitha efuna ukuphathwa ngokuthe ngqo.Ukusetyenziswa kwegranite emnyama kweli shishini kungenxa yeempawu zayo ezixineneyo, nto leyo eyenza ibe yeyona nto ibalaseleyo yokuzikhusela kwimitha.
Ngamafutshane, izikhokelo zegranite emnyama zizinto ezibalulekileyo kwishishini lemveliso, ezithatha uluhlu olubanzi lwezicelo ezivela kwi-semiconductor, optics, i-aerospace, ukukhusela, kunye namashishini enyukliya.Ukusetyenziswa kwegranite emnyama kula mashishini ngenxa yeempawu zayo ezikhethekileyo, ezifana nokuzinza kwe-thermal, ukuzinza kwe-dimensional, ukumelana nokugqoka okuphezulu, kunye neempawu eziphezulu, ukubiza ezimbalwa.Izikhokelo ezenziwe ngegranite emnyama ziqinisekisa ukuchaneka kunye nokuthembeka kwezixhobo zokulinganisa kunye nokuvavanya, ukubonelela ngeqonga elizinzile kunye nesicaba sokuvavanya ngokuchanekileyo kunye nomatshini ochanekileyo.
