Imishini yokulinganisa ehlanganisiwe (ama-CMM) iyimishini yokulinganisa eyinkimbinkimbi esetshenziswa ezimbonini lapho kudingeka khona izilinganiso eziqondile, njengokukhiqiza izindiza, izimoto, kanye namadivayisi ezokwelapha. Le mishini isebenzisa izingxenye ze-granite ngenxa yokuqina kwazo okuphezulu, ukuzinza okuhle kakhulu kokushisa, kanye ne-coefficient ephansi yokwanda kokushisa, okwenza zibe zilungele ukusetshenziswa kokulinganisa okunembile kakhulu. Kodwa-ke, izingxenye ze-granite nazo zivame ukudlidliza nokushaqeka, okungonakalisa ukunemba kokulinganisa. Yingakho abakhiqizi be-CMM bethatha izinyathelo zokuhlukanisa nokumunca ukudlidliza nokushaqeka ezingxenyeni zabo ze-granite.
Esinye sezinyathelo eziyinhloko zokuhlukanisa ukudlidliza kanye nokumuncwa kokushaqeka ukusetshenziswa kwezinto zegranite ezisezingeni eliphezulu. Le nto ikhethwa ngenxa yokuqina kwayo okuphezulu, okusiza ukunciphisa noma yikuphi ukunyakaza okubangelwa amandla angaphandle kanye nokudlidliza. Igranite iphinde imelane kakhulu nokukhula kokushisa, okusho ukuthi igcina isimo sayo ngisho nalapho kukhona ukushintshashintsha kwezinga lokushisa. Lokhu kuzinza kokushisa kuqinisekisa ukuthi izilinganiso zihlala zinembile, ngisho nangaphansi kwezimo zemvelo ezahlukahlukene.
Esinye isilinganiso esisetshenziswa ukuthuthukisa ukuzinza kwezingxenye ze-granite ukubeka izinto ezibamba ukushaqeka phakathi kwesakhiwo se-granite kanye nomshini wonke. Isibonelo, amanye ama-CMM anepuleti elikhethekile elibizwa ngokuthi i-damping plate, elinamathiselwe esakhiweni se-granite somshini. Leli puleti lenzelwe ukumunca noma yikuphi ukudlidliza okungase kudluliselwe ngesakhiwo se-granite. Ipuleti lokudambisa liqukethe izinto ezahlukahlukene, njengerabha noma amanye ama-polymer, amunca amaza okudlidliza futhi anciphise umthelela wawo ekunembeni kokulinganisa.
Ngaphezu kwalokho, ama-air bearings anembile angenye indlela esetshenziselwa ukwahlukanisa ukudlidliza kanye nokumuncwa kokushaqeka. Umshini we-CMM uphumule ochungechungeni lwama-air bearings asebenzisa umoya ocindezelwe ukuntanta isitimela sokuqondisa i-granite ngaphezu komcamelo womoya. Ama-air bearings ahlinzeka ngendawo ebushelelezi nezinzile ukuze umshini uhambe, ngokungqubuzana okuncane kanye nokuguguleka. Lawa ma-bearings asebenza futhi njengesithambisi sokushaqeka, amunca noma yikuphi ukudlidliza okungafuneki futhi awavimbele ekudluleleni esakhiweni se-granite. Ngokunciphisa ukuguguleka nokunciphisa amandla angaphandle asebenza emshinini, ukusetshenziswa kwama-air bearings anembile kuqinisekisa ukuthi i-CMM igcina ukunemba kwayo kokulinganisa ngokuhamba kwesikhathi.
Ekuphetheni, ukusetshenziswa kwezingxenye ze-granite emishinini ye-CMM kubalulekile ekufinyeleleni izilinganiso ezinembile kakhulu. Nakuba lezi zingxenye zingase zidlidlize futhi zishaqeke, izinyathelo ezisetshenziswa abakhiqizi be-CMM zinciphisa imiphumela yazo. Lezi zinyathelo zifaka phakathi ukukhetha izinto ze-granite ezisezingeni eliphezulu, ukufaka izinto ezimunca ukushaqeka, nokusebenzisa ama-air bearings anembile. Ngokusebenzisa lezi zinyathelo zokuhlukaniswa kokudlidliza kanye nokumunca ukushaqeka, abakhiqizi be-CMM bangaqinisekisa ukuthi imishini yabo iletha izilinganiso ezithembekile nezinembile njalo.
