Umshini wokulinganisa i-bridge coordinate (CMM) ubhekwa kabanzi njengenye yamathuluzi okulinganisa anembe kakhulu atholakala embonini. Ukunemba kwaleli thuluzi kuncike ezintweni eziningana ezibalulekile, njengekhwalithi yama-probe okulinganisa kanye nesofthiwe yokulawula. Isici esisodwa esibalulekile esingathinta kakhulu ububanzi bokulinganisa kanye nokunemba kwe-CMM ukukhetha izinto zombhede/umzimba.
Ngokwesiko, ama-CMM ebhuloho akhiwa kusetshenziswa insimbi ephothiwe, into enokuqina okuhle kakhulu nokuzinza. Kodwa-ke, eminyakeni yamuva nje, i-granite isibe yindlela ethandwayo. Abakhiqizi abaningi manje bakhetha i-granite ngenxa yezakhiwo zayo ezinhle kakhulu zomshini kanye nokuzinza kokushisa.
Ngokungafani nensimbi ephonswe ngensimbi, i-granite ine-coefficient ephansi kakhulu yokwanda kokushisa, okwenza ingabi sengozini yokuguquguquka kokushisa okubangelwa ukushintshashintsha kwezinga lokushisa. Lokhu kuzinza kokushisa kuvumela i-CMM ukuthi igcine ukunemba kwayo phezu kobubanzi bokushisa obusebenzayo, okuqinisekisa ukuthi izilinganiso zinembile futhi ziyavumelana.
Enye inzuzo yokusebenzisa i-granite embhedeni we-CMM yizakhiwo zayo zemvelo zokudambisa. I-granite inamandla aphezulu okudambisa uma iqhathaniswa nensimbi ephonswe ngensimbi, okusiza ukunciphisa umphumela wokudlidliza komshini okubangelwa ukuphathwa noma izici zemvelo. Ngokunciphisa lokhu kudlidliza, umbhede we-granite uqinisekisa ukuthi ama-probe okulinganisa angafinyelela ukufundwa okuzinzile nokunembile, anciphise amaphutha futhi anciphise isidingo sokulinganisa.
Ngaphezu kwalokho, i-granite ayigugi kakhulu uma iqhathaniswa ne-cast iron. Ngokuhamba kwesikhathi, ubuso bombhede we-cast iron bungase bube nezimbobo noma buklwebhe, okuholela ekungalungini kwenqubo yokulinganisa. Ngakolunye uhlangothi, i-granite imelana kakhulu nomonakalo onjalo, okuqinisekisa ukuthi ukunemba komshini kuhlala kufana phakathi nomjikelezo wawo wokuphila.
Enye inzuzo ebalulekile ye-granite yikhono layo lokusingatha imithwalo esindayo. Njengoba inamandla aphezulu okucindezela kanye nokuqina okuhle kakhulu, iyakwazi ukumelana nezinto zokusebenza ezisindayo ngaphandle kokuphazamisa ukunemba kwayo.
Ekuphetheni, umbhede wegranite uyingxenye ebalulekile ye-CMM yebhuloho yesimanje, enikeza izinzuzo eziningana ngaphezu kwezinto zendabuko njengensimbi ephonswe ngensimbi. Inikeza ukuzinza okuphezulu kokushisa, ukumanzisa, kanye nezakhiwo ezingagugi, okuqinisekisa ukuthi umshini ungagcina ukunemba kwawo nokungaguquguquki isikhathi eside. Ngaphezu kwalokho, ikhono lawo lokusingatha imithwalo esindayo lenza libe ithuluzi eliguquguqukayo kakhulu lokulinganisa izinto zokusebenza ezinkulu ngokunembile. Sekukonke, ukusetshenziswa kwegranite ngokungangabazeki kuyintuthuko enhle ekuthuthukisweni kwe-CMM yebhuloho, okuzoqhubeka nokuthuthukisa ukunemba nokuthembeka kwala mathuluzi iminyaka ezayo.
