Kubunjiniyela bokucacisa, ukunemba kwamathuluzi okulinganisa kunquma ukuthembeka kwenqubo yonke yokukhiqiza. Ngenkathi amathuluzi okulinganisa i-granite ne-ceramic ebusa imboni yokucacisa kakhulu namuhla, amathuluzi okulinganisa imabula ake asetshenziswa kabanzi futhi asasetshenziswa ezindaweni ezithile. Kodwa-ke, ukukhiqiza amathuluzi okulinganisa imabula afanelekayo kuyinkimbinkimbi kakhulu kunokusika nokupholisha itshe nje—izindinganiso zobuchwepheshe eziqinile kanye nezidingo zezinto kumele zilandelwe ukuqinisekisa ukunemba kokulinganisa kanye nokuzinza kwesikhathi eside.
Isidingo sokuqala sisekukhetheni izinto ezibonakalayo. Izinhlobo ezithile kuphela zemabula yemvelo ezingasetshenziswa ngamathuluzi okulinganisa. Itshe kumele libe nesakhiwo esiminyene, esifanayo, okusanhlamvu okuhle, kanye nokucindezeleka okuncane kwangaphakathi. Noma yikuphi ukuqhekeka, imithambo, noma ukushintshashintsha kombala kungaholela ekuguqukeni noma ekungazinzini ngesikhathi sokusetshenziswa. Ngaphambi kokucubungula, amabhlogo emabula kumele avuthwe ngokucophelela futhi ancishiswe ukucindezeleka ukuze kuvinjelwe ukuphambuka kwesimo ngokuhamba kwesikhathi. Ngokungafani nemabula yokuhlobisa, imabula yokulinganisa kumele ihlangabezane nezinkomba zokusebenza ngokomzimba eziqinile, kufaka phakathi amandla okucindezela, ubulukhuni, kanye nokugoba okuncane.
Ukuziphatha kokushisa kungenye into ebalulekile. Imabula ine-coefficient ephezulu yokwanda kokushisa uma iqhathaniswa ne-granite emnyama, okusho ukuthi izwa kakhulu izinguquko zokushisa. Ngakho-ke, ngesikhathi sokukhiqiza nokulinganisa, indawo yokusebenza kumele igcine izinga lokushisa elilinganayo kanye nomswakama ukuqinisekisa ukunemba. Amathuluzi okulinganisa imabula afaneleka kangcono ezindaweni ezilawulwayo njengeelebhu, lapho ukushintshashintsha kwezinga lokushisa kuncane khona.
Inqubo yokukhiqiza idinga izinga eliphezulu lobuciko. Ipuleti ngalinye elingaphezulu lemabula, i-straightedge, noma i-square ruler kumele lidlule ezigabeni eziningana zokugaya okuqinile, ukugaya okuncane, kanye nokubopha ngesandla. Ochwepheshe abanolwazi bathembele kumathuluzi okuthinta nokunemba ukuze bafinyelele ukuthamba kwezinga le-micrometer. Inqubo iqashwa kusetshenziswa amadivayisi okulinganisa athuthukile njenge-laser interferometers, amazinga e-elekthronikhi, kanye nama-autocollimator. Lezi zinyathelo ziqinisekisa ukuthi ipuleti ngalinye elingaphezulu noma i-ruler lihambisana nezindinganiso zomhlaba wonke njenge-DIN 876, ASME B89, noma i-GB/T.
Ukuhlolwa nokulinganiswa kwakha enye ingxenye ebalulekile yokukhiqiza. Ithuluzi ngalinye lokulinganisa imabula kumele liqhathaniswe nezindinganiso zokubhekisela eziqinisekisiwe ezilandelwa yizikhungo zikazwelonke ze-metrology. Imibiko yokulinganisa iqinisekisa ukuthi ithuluzi liyisicaba, liqondile, futhi liyisikwele, liqinisekisa ukuthi lihlangabezana nokubekezelelana okucacisiwe. Ngaphandle kokulinganiswa okufanele, ngisho nobuso bemabula obucwebezelisiwe kakhulu abukwazi ukuqinisekisa ukulinganiswa okunembile.
Nakuba amathuluzi okulinganisa imabula enikeza ukuphela okubushelelezi futhi engabizi kakhulu, nawo anemikhawulo. Ukubhoboka kwawo kuwenza athambekele kakhulu ekumuncweni nasekufakweni komswakama, futhi ukuzinza kwawo kungaphansi kwalokho kwe-granite emnyama enobukhulu obuphezulu. Yingakho izimboni eziningi zesimanje ezinembayo ephezulu—njenge-semiconductors, i-aerospace, kanye nokuhlolwa kwe-optical—zikhetha amathuluzi okulinganisa i-granite. Kwa-ZHHIMG, sisebenzisa i-granite emnyama ye-ZHHIMG®, enobukhulu obuphezulu kanye nokusebenza okungcono ngokomzimba kune-granite emnyama yaseYurophu noma yaseMelika, enikeza ubulukhuni obuphezulu, ukumelana nokuguguleka, kanye nokuzinza kokushisa.
Noma kunjalo, ukuqonda izidingo eziqinile zokukhiqizwa kwamathuluzi okulinganisa imabula kunikeza ukuqonda okubalulekile ngokuvela kwe-precision metrology. Isinyathelo ngasinye—kusukela ekukhetheni izinto zokusetshenziswa kuya ekuqedeni nasekulinganisweni—simelela ukuphishekela ukunemba okuchaza yonke imboni yokunemba. Okuhlangenwe nakho okutholakale ekucutshungulweni kwemabula kwabeka isisekelo sobuchwepheshe besimanje bokulinganisa i-granite kanye ne-ceramic.
Kwa-ZHHIMG, sikholelwa ukuthi ukunemba kwangempela kuvela ekunakeni imininingwane ngokungaguquki. Kungakhathaliseki ukuthi sisebenza ngemabula, i-granite, noma izinto zobumba ezithuthukisiwe, umgomo wethu uhlala ufana: ukukhuthaza intuthuko yokukhiqiza ngokunemba okukhulu ngokusebenzisa ukusungula izinto ezintsha, ubuqotho, kanye nobuciko.
