Oomatshini bokulinganisa abadibeneyo (ii-CMM) zizixhobo zokulinganisa ezintsonkothileyo ezisetyenziswa kumashishini apho kufuneka khona imilinganiselo echanekileyo, njengokwenziwa kweenqwelo-moya, iimoto, kunye nezixhobo zonyango. Aba matshini basebenzisa izixhobo zegranite ngenxa yokuqina kwazo okuphezulu, uzinzo oluhle kakhulu lobushushu, kunye ne-coefficient ephantsi yokwandiswa kobushushu, okwenza ukuba zilungele ukusetyenziswa kokulinganisa okuchanekileyo. Nangona kunjalo, izixhobo zegranite nazo zinokuphazamiseka kokungcangcazela kunye nokutsha, okunokonakalisa ukuchaneka kokulinganisa. Yiyo loo nto abavelisi be-CMM bethatha amanyathelo okwahlula nokufunxa ukungcangcazela kunye nokutshaqeka kwiindawo zabo zegranite.
Enye yeendlela eziphambili zokwahlula ukungcangcazela kunye nokufunxwa komothuko kukusebenzisa izinto zegranite ezikumgangatho ophezulu. Ezi zinto zikhethwe ngenxa yokuqina kwazo okuphezulu, okunceda ukunciphisa nayiphi na intshukumo ebangelwa ngamandla angaphandle kunye nokungcangcazela. Igranite ikwamelana kakhulu nokwanda kobushushu, oko kuthetha ukuba igcina imo yayo nokuba kukho ukuguquguquka kobushushu. Olu zinzo lobushushu luqinisekisa ukuba imilinganiselo ihlala ichanekile, nokuba phantsi kweemeko ezahlukeneyo zokusingqongileyo.
Elinye inyathelo elisetyenziswayo ukuphucula uzinzo lwezixhobo zegranite kukubeka izinto ezifunxa ukutshaqeka phakathi kwesakhiwo segranite kunye nomatshini wonke. Umzekelo, ezinye iiCMM zinepleyiti ekhethekileyo ebizwa ngokuba yi-damping plate, enamathele kwisakhiwo segranite somatshini. Le pleyiti yenzelwe ukufunxa naluphi na ungcangcazelo olunokudluliselwa ngesakhiwo segranite. Ipleyiti yokufunxa iqulethe izinto ezahlukeneyo, ezifana nerabha okanye ezinye iipolymers, ezifunxa amaza okungcangcazela kwaye zinciphise impembelelo yazo ekuchanekeni kokulinganisa.
Ngaphezu koko, ii-precision air bearings zezinye iindlela zokulinganisa ezisetyenziselwa ukwahlukanisa ukungcangcazela kunye nokufunxwa komothuko. Umatshini we-CMM uxhomeke kuthotho lwee-air bearings ezisebenzisa umoya ocinezelweyo ukudada i-granite guide rail ngaphezulu komqamelo womoya. Ii-air bearings zibonelela ngomphezulu ogudileyo nozinzileyo ukuze umatshini ukwazi ukuhamba, kunye nokungqubana okuncinci kunye nokuguguleka. Ezi bearings zikwasebenza njenge-shock absorber, zifunxa naziphi na ii-vibrations ezingafunekiyo kwaye zithintele ukuba zingadluli kwisakhiwo se-granite. Ngokunciphisa ukuguguleka kunye nokunciphisa amandla angaphandle asebenza kumatshini, ukusetyenziswa kwee-precision air bearings kuqinisekisa ukuba i-CMM igcina ukuchaneka kwayo kokulinganisa ngokuhamba kwexesha.
Ukuqukumbela, ukusetyenziswa kwezinto zegranite kwiimashini zeCMM kubalulekile ekufezekiseni imilinganiselo echanekileyo. Nangona ezi zinto zichaphazeleka kukungcangcazela kunye nokukhwaza, amanyathelo asetyenziswa ngabavelisi beCMM anciphisa iziphumo zawo. La manyathelo aquka ukukhetha izinto zegranite ezikumgangatho ophezulu, ukufaka izinto ezifunxa ukukhwaza, kunye nokusebenzisa iibheringi zomoya ezichanekileyo. Ngokusebenzisa la manyathelo okwahlula ukungcangcazela kunye nokufunxa ukukhwaza, abavelisi beCMM banokuqinisekisa ukuba oomatshini babo banika imilinganiselo ethembekileyo nechanekileyo ngalo lonke ixesha.
