Imishini yokulinganisa edidiyelwe (ama-CMM) ingeminye yemishini esetshenziswa kakhulu ezimbonini ezahlukene zokukhiqiza ngenxa yokunemba kwayo nokunemba kwayo ekulinganiseni amajiyomethri ezinto. Enye yezingxenye ezibalulekile zama-CMM yisisekelo lapho izinto zibekwa khona ukuze zilinganiswe. Enye yezinhlobo ezivamile zezinto ezisetshenziswa ukwenza izisekelo ze-CMM yi-granite. Kulesi sihloko, sizobheka izinhlobo ezahlukene zezisekelo ze-granite ezisetshenziswa kuma-CMM.
I-Granite iyinto ethandwayo yezisekelo ze-CMM ngoba izinzile, iqinile, futhi ine-coefficient ephansi kakhulu yokwanda kokushisa, okusho ukuthi ubukhulu bayo abuthinteki kalula ngokushintsha kwezinga lokushisa. Ukwakheka kwezisekelo ze-granite kuyahlukahluka kuye ngohlobo lwe-CMM kanye nomkhiqizi. Kodwa-ke, nansi eminye yezinhlobo ezahlukene zezisekelo ze-granite ezisetshenziswa kuma-CMM.
1. Isisekelo Se-Granite Esiqinile: Lolu uhlobo oluvame kakhulu lwesisekelo se-granite esisetshenziswa kuma-CMM. I-granite eqinile ifakwa ngomshini ngokwezidingo ezidingekayo futhi inikeza ukuqina okuhle nokuzinza emshinini wonke. Ubukhulu besisekelo se-granite buyahlukahluka kuye ngobukhulu be-CMM. Uma umshini umkhulu, isisekelo siba sikhulu.
2. Isisekelo Se-Granite Esicindezelwe Ngaphambili: Abanye abakhiqizi bafaka i-prestressing ku-granite slab ukuze bathuthukise ukuzinza kwayo okulinganayo. Ngokufaka umthwalo ku-granite bese uyifudumeza, i-slab iyadonswa bese idedelwa ukuze iphole ifinyelele kubukhulu bayo bokuqala. Le nqubo ibangela ukucindezeleka okucindezelayo ku-granite, okusiza ekuthuthukiseni ukuqina kwayo, ukuzinza kwayo, kanye nokuphila isikhathi eside.
3. Isisekelo seGranite Esithwala Umoya: Ama-air bearing asetshenziswa kwamanye ama-CMM ukusekela isisekelo segranite. Ngokupompa umoya nge-bearing, i-granite iyantanta ngaphezu kwayo, okwenza ingabi nokungqubuzana ngaleyo ndlela inciphise ukuguguleka nokuguga komshini. Ama-air bearing awusizo kakhulu kuma-CMM amakhulu ashukunyiswa njalo.
4. Isisekelo se-Honeycomb Granite: Isisekelo se-honeycomb granite sisetshenziswa kwamanye ama-CMM ukunciphisa isisindo sesisekelo ngaphandle kokuphazamisa ukuqina nokuqina kwaso. Isakhiwo se-honeycomb senziwe nge-aluminium, futhi i-granite inamathiselwe phezulu. Lolu hlobo lwesisekelo lunikeza ukudlidliza okuhle futhi lunciphisa isikhathi sokufudumala komshini.
5. Isisekelo Esihlanganisiwe Segranite: Abanye abakhiqizi be-CMM basebenzisa izinto ezihlanganisiwe zegranite ukwenza isisekelo. I-granite composite yenziwa ngokuxuba uthuli lwegranite kanye ne-resin ukuze kudalwe izinto ezihlanganisiwe ezilula futhi ezihlala isikhathi eside kunegranite eqinile. Lolu hlobo lwesisekelo alukwazi ukugqwala futhi lunokuqina okungcono kokushisa kunegranite eqinile.
Ekuphetheni, ukwakheka kwezisekelo ze-granite kuma-CMM kuyahlukahluka kuye ngohlobo lomshini kanye nomkhiqizi. Imiklamo ehlukene inezinzuzo nezinkinga ezahlukene, okwenza ifaneleke ukusetshenziswa okuhlukile. Kodwa-ke, i-granite ihlala ingenye yezinto ezinhle kakhulu zokwenza izisekelo ze-CMM ngenxa yokuqina kwayo okuphezulu, ukuzinza, kanye ne-coefficient yokwanda kokushisa okuphansi.
