Abaguzi benshi bibaza ibijyanye no kwihanganira guhagarara kw'inzu iyo batumijeisahani yo hejuru ya granite. Abake ni bo bibaza igihe ubwo bwumvikane buzamara. Ni ikibazo cyiza cyo gusimbuka iyo ugereranya amagambo, ariko ni cyo kirangira gifite akamaro mu myaka itatu cyangwa itanu y'akazi k'umuntu - kandi niho icyuho kiri hagati y'amanota kigaragara.
Amasahani yo hejuru ya granite akunze gushyirwa mu byiciro hakurikijwe ibipimo ngenderwaho nka DIN 876, ASME B89.3.7, cyangwa GB/T 22095, aho amanota ava kuri AA akagera kuri A, B, na 0/00 bitewe n'ibipimo ngenderwaho byakoreshejwe. Amasahani ya 00 ari hejuru - uburyo bwo kwihanganira uburebure bw'isahani bushobora kwemezwa, muri rusange bugenewe amasahani y'icyitegererezo, amasahani yo gupima, n'ikoreshwa aho ibindi bipimo byose mu nyubako bikurikiranwa kuri ubwo buso bumwe. Igice gishimishije si umubare w'ibanze uri ku cyemezo. Ni uko biba kuri uwo mubare uko igihe kigenda gihita.
Impamvu amasahani yo mu rwego rwo hasi ahindagurika vuba
Ubugari bw'ikibaho cyo hejuru si ikintu kidahinduka; ni ishusho yafashwe mu isuzuma rya nyuma. Kuva icyo gihe, hari ibintu bitatu bigaragaza uburyo gifata neza:
Ubucucike bw'ibikoresho n'imiterere y'ibinyampeke. Ibuye rifite ubucucike buke, cyangwa ibuye rifite ubucucike budahuje, rikunda kwangirika mu buryo budahuje iyo rikoreshejwe mu buryo butunguranye kandi igice cyaryo kigakoraho. Uduce duto duto twa microscopic dusenyuka vuba kurusha ubuso bukikije, kandi imiterere y'icyuma gifunganye itangira guhinduka - buhoro buhoro mu ntangiriro, hanyuma ikagaragara nyuma y'imyaka mike ikoreshwa buri munsi. Granite y'umukara iremereye, iri hagati ya 3,000+ kg / m³, irwanya ubu bwoko bw'ingufu zitandukanye, ari na yo mpamvu ari yo ikoreshwa mu kazi ko mu cyiciro cya 00 aho kuba ibuye ryoroheje cyangwa rifite imyenge myinshi.
Ubwiza bwo gusya no gusimbuza. Ingano y'isahani isya kugeza ku rwego rwa 00 ntabwo iba imeze neza ku munsi wa mbere gusa - akenshi irangizwa n'uburyo ndende kandi bugenzurwa bwo gusimbuza busiga imiterere y'ubuso bumwe munsi y'ubushobozi bwo gupima. Isahani yo mu rwego rwo hasi ishobora kuba ifite umubare ungana neza n'uwo mubare, ikagerwaho binyuze mu gutunganya vuba, ariko ikaba idafite ubusumbane bwinshi mu kurangiza munsi y'isahani. Iryo tandukaniro ntirigaragara ku rupapuro rw'igenamigambi; rigaragara mu buryo isaza ry'isaha.
Gufata no kubika nyuma yo kwemezwa, nk'uko twabigarutseho ahandi, ariko bikwiye kugarukwaho hano - ndetse n'isahani yo mu rwego rwa 00 itakaza inyungu zayo iyo ibitswe ahantu hatangana cyangwa igasigara mu cyumba gifite ubushyuhe buke.
Icyo ibi bivuze ku ngendo zo gupima
Mu by’ukuri, itandukaniro ry’amanota risobanurwa inshuro zo kongera gupima. Iduka rikoresha icyapa cya Grade B ku murongo w’ibikorwa byinshi rishobora gukenera kongera gusuzuma no kongera kugipima buri mwaka, rimwe na rimwe akenshi bitewe n’uko gikoreshwa. Icyapa cy’icyitegererezo cya Grade 00, gifashwe neza mu buryo bugenzurwa, akenshi gishobora kumara imyaka ibiri cyangwa itatu hagati yo kongera gupima byuzuye - nubwo ibi bitandukanye bitewe n’ikoreshwa kandi ntibikwiye gufatwa nk'itegeko rihoraho. Kuri laboratwari yo gupima cyangwa ishami ry’ibipimo rikora nk'ahantu ho gupima ikigo cyose, icyo gihe kirekire si ukugabanya ikiguzi gusa. Bigabanya inshuro umusaruro ugomba guhagarara, cyangwa ikindi cya kabiri kigomba kuzana, mu gihe icyapa cy’ibanze kidakora neza.
Twakoresheje plaque za Grade 00 ku bakiriya bazikoresha nk'icyitegererezo cy'ingenzi aho icyumba cyabo cyose cya CMM cyemezwa - amashami ya kaminuza apima, ibigo by'igihugu, n'inganda nke za Fortune 500 muri zo. Igitangaza abaguzi ba mbere si umubare w'ubugari ubwawo, kuko abatanga ibicuruzwa benshi bemewe bashobora kubona imibare nk'iyo ku mpapuro. Ni icyifuzo, nyuma y'umwaka umwe cyangwa ibiri, cy'uko amakuru y'igenzura ry'umwimerere agereranywa n'igenzura ryongeye gukorwa - hanyuma ugasanga itandukaniro riri mu gice gito cy'icyemezo cy'umwimerere. Ubwo buryo bwo gusubiramo igenzura, bukozwe mu buryo buboneye hakoreshejwe ibikoresho bishobora gukurikiranwa, ni bwo buryo bwonyine bwo kumenya niba ikirego cya Grade 00 cyarabonetse cyangwa cyapimwe rimwe gusa mu bihe byiza.
Icyitonderwa Gifatika ku Baguzi
Icyiciro cya 00 si ngombwa kuri buri gikorwa cyose — ku igenzura rusange cyangwa imirimo yo guteranya, icyapa cya A cyangwa B akenshi ni cyo gikunze kuba amahitamo meza kandi ahendutse. Ariko ku byerekeye imfashanyigisho za master, gupima, cyangwa uruhare urwo arirwo rwose aho icyapa ubwacyo kiba ari cyo gisanzwe, ibindi bikoresho bigenzurwa, ubwiza bw'igihe kirekire bw'icyapa cyakozwe neza cya 00 butuma habaho ikiguzi cyo hejuru mbere y'igihe. Ikizamini nyacyo si icyemezo cyoherezwa hamwe n'icyapa. Ni cyo icyo cyemezo kikivuga mu myaka itatu, mu bihe byose icyapa cyabayemo.
