Ku bijyanye no gupima neza, plaque ya granite ifatwa nkibipimo bya zahabu. Imyitwarire yabo isanzwe, uburinganire budasanzwe, hamwe no kurwanya kwambara bituma biba ingenzi muri laboratoire ya metero, ibyumba byo kugenzura ubuziranenge, hamwe n’ibikorwa byo mu rwego rwo hejuru. Nyamara, mugihe abakoresha benshi bibanda ku buso bwuzuye no kwihanganirana, hari ikindi kintu cyingenzi kigira ingaruka ku mikorere no kuramba kw'isahani ya granite - ubunini bwayo. Gusobanukirwa nuburyo umubyimba wagenwe nuburyo bifitanye isano nubushobozi bwo kwikorera no gutuza ni urufunguzo rwo guhitamo urubuga rukwiye kubikoresho byawe no kwemeza neza igihe kirekire cyo gupima.
Ubunini bwa plaque ya granite burenze kure cyane ibipimo. Ni umusingi wuburinganire bwisahani. Ubunini bwa granite, nubushobozi bwayo bwo gushyigikira ibikoresho biremereye bitagunamye cyangwa ngo bihindukire. Ibi bigira ingaruka ku buryo butaziguye kwizerwa kuko niyo gutandukana gake - rimwe na rimwe bipimirwa muri micron - birashobora gutuma habaho amakosa mu kugenzura cyangwa kuri kalibrasi. Kurundi ruhande, isahani ifite umubyimba mwinshi irashobora kuba iremereye bitari ngombwa, ihenze, kandi kuyishyiraho. Igisubizo cyiza kiri mukuringaniza ubunini hamwe nibisabwa na porogaramu.
Kimwe mubitekerezo byibanze mugihe cyo kumenya ubunini nuburemere bwibikoresho bizashyirwa ku isahani. Kubikorwa byoroheje-bikorwa - nka microscopes, gipima, cyangwa ibikoresho bito byo gupima - isahani yoroheje irashobora kuba ihagije, kuko umutwaro washyizweho ni muto. Ariko uko ibiro byiyongera, niko bigomba kuba binini. Imashini nka mashini yo gupima (CMMs), sisitemu yo gupima optique, cyangwa ibikoresho byo guteranya biremereye bigira imbaraga zikomeye hejuru, kandi isahani ifite umubyimba udahagije irashobora guhinduka buhoro buhoro munsi yumutwaro. Igihe kirenze, uku guhindura ibintu biganisha ku gutakaza uburinganire, kubangamira intego yo gukoresha isahani yuzuye.
Umubyimba kandi ugira uruhare runini mubushobozi bwisahani yo kurwanya ibidukikije. Granite isanzwe yaguka kandi igasezerana cyane nihindagurika ryubushyuhe, ariko amasahani manini arwanya cyane ihindagurika ryumuriro. Bafite misa nini yubushyuhe, bivuze ko bitwara buhoro buhoro kubushyuhe butandukanye, bufasha kugumya guhagarara neza nubwo ibidukikije bidakwiriye. Iyi mikorere ifite agaciro cyane mumahugurwa cyangwa mubikorwa byo gukora aho kugenzura ubushyuhe bigoye.
Ikindi kintu cyatewe nubunini nubuzima bwigihe kirekire bwa plaque ya granite. Isahani ifite umubyimba wukuri kubisabwa irashobora kuguma ihamye kandi neza mumyaka mirongo. Ibinyuranyo, imwe yoroheje cyane kumutwaro ishyigikira irashobora kubanza kuzuza ibisabwa ariko buhoro buhoro igatakaza ubusobanuro bwayo uko imyaka ishira. Ubu bwoko bwo guhindura ibintu buhoro buhoro ntibusubira inyuma kandi birashobora gusaba guhindurwa bihenze cyangwa gusimburwa byuzuye.
Inganda zinganda nka DIN, JIS, na ASME zitanga ubunini busabwa kubunini bwa plaque zitandukanye hamwe n amanota yukuri, ariko ibyo bigomba gufatwa nkamabwiriza aho kuba amategeko akomeye. Porogaramu yose irihariye, kandi nibintu nkumutwaro wose, uburyo umutwaro wagabanijwe, kuba hari imbaraga zingirakamaro, nubwoko bwimiterere yingoboka ikoreshwa munsi yisahani byose bishobora guhindura umubyimba mwiza. Burigihe nibyiza kugisha inama nuwabikoze mugihe ugaragaza isahani ya granite, cyane cyane kubisanzwe bitari bisanzwe cyangwa biremereye cyane.
Mu buryo bufatika, isano iri hagati yubunini, ubunini, n'imikorere iroroshye. Isahani nini ikenera umubyimba munini kugirango igumane ubukana hejuru yubuso bwabo, kandi amanota yukuri arasaba ibyapa binini kugirango agabanye gutandukana. Kurugero, isahani ya mm 1000 ikoreshwa mubugenzuzi rusange irashobora kuba ifite uburebure bwa mm 150, mugihe isahani ya mm 2000 ishyigikira imashini ipima uburemere ishobora gusaba mm 300 cyangwa zirenga. Abakora nka ZHHIMG batanga ibisobanuro birambuye hamwe nubushobozi bwo kwikorera imitwaro kugirango bayobore abakiriya kugishushanyo mbonera gikenewe kubyo bakeneye.
Kubungabunga nabyo bigira uruhare mukuzigama imikorere ya plaque ya granite, tutitaye kubyimbye. Kugira isuku hejuru kandi idafite umukungugu, kwirinda ingaruka zitunguranye, no kwemeza ko isahani itaremerewe ni ibintu byingenzi. Kugenzura buri gihe kandi birasabwa kugenzura niba uburinganire buguma mu mbibi zemewe. Hamwe nubwitonzi bukwiye, isahani yatoranijwe neza irashobora gutanga ibipimo bihamye kandi byizewe mumyaka mirongo.
Mu kurangiza, umubyimba nturenze gupima umubiri gusa - ni ikintu gikomeye cyubwubatsi bushimangira imikorere, kuramba, hamwe nibisobanuro bya plaque ya granite. Urebye neza uburemere bwibikoresho byawe, ibidukikije bizakoreshwa isahani, hamwe nubuzima bwa serivisi uteganijwe, urashobora guhitamo urubuga ruzashyigikira ibikorwa byawe neza mumyaka myinshi. Mugihe kwihanganira inganda bigenda birushaho gukomera no gupima neza cyane kuruta ikindi gihe cyose, kwitondera amakuru arambuye nkubunini bwa plaque ntabwo ari tekiniki gusa - ni inyungu zo guhatanira.
