Nigute Precision yavutse? Gusesengura Igishushanyo cya Granite no Kubungabunga neza

Mubikorwa bihanitse cyane byo gukora no gupima, icyapa cya granite nicyo shingiro ridashidikanywaho-zero-point yo gupima ibipimo. Ubushobozi bwayo bwo gufata indege hafi-yuzuye ntabwo ari kamere karemano gusa, ahubwo ni ibisubizo byuburyo bugenzurwa neza, bikurikirwa no kubungabunga gahunda. Ariko ni uruhe rugendo rusobanutse icyapa cya granite gifata kugirango ugere ku gutungana gutya, kandi ni izihe protocole zikenewe kugirango ikomeze? Ku ba injeniyeri n'abashinzwe ubuziranenge, gusobanukirwa inkomoko y'ibi bisobanuro n'intambwe zikenewe zo kubibungabunga ni ngombwa mu gukomeza ireme ry'inganda.

Igice cya 1: Uburyo bwo Gushiraho-Ubwubatsi bwa Flatness

Urugendo rwibisate bya granite, kuva kumurongo uciwe kugeza ku cyerekezo cyo hejuru-isahani, ikubiyemo urukurikirane rwo gusya, gutuza, no kurangiza ibyiciro, buri kimwe cyagenewe kugabanya buhoro buhoro ikosa ryibipimo.

Mu ikubitiro, nyuma yo gukata, icyapa gikorerwa Shape Shape no Gusya. Iki cyiciro gikuraho ibintu byinshi kugirango hamenyekane hafi ya geometrie yanyuma hamwe nuburinganire. Icy'ingenzi, iyi nzira ikora kandi kugirango irekure byinshi mubibazo bisigara byubatswe byubaka mumabuye mugihe cyo gucukura no gutema bwa mbere. Mugihe twemereye icyapa "gutuza" no kongera gutuza nyuma ya buri ntambwe ikomeye yo gukuraho ibintu, turinda ejo hazaza gutembera, tukemeza ko umutekano urambye.

Guhinduka kwukuri bibaho mugihe cyubuhanzi bwa Lapping. Gukubita ni inzira yanyuma, yihariye cyane itunganya igice cya tekinike hejuru yindege yemewe. Ntabwo ari ugusya imashini; nigikorwa cyitondewe, cyihuta, imikorere yumuvuduko mwinshi. Twifashishije ibibyimba byiza, bidakabije-akenshi bya diyama-byahagaritswe muburyo bwamazi, bigashyirwa hagati yubuso bwa granite hamwe nicyapa gikomeye. Icyerekezo kigenzurwa neza kugirango ukureho ibintu bimwe hejuru. Ingaruka yo kugereranya, isubirwamo intoki na mehanike muntambwe itera, igenda itunganya buhoro buhoro muri micron cyangwa se na microne (yujuje ubuziranenge nka ASME B89.3.7 cyangwa ISO 8512). Ibisobanuro byagezweho hano ntabwo ari bike kubijyanye na mashini nibindi bijyanye nubuhanga bwabakoresha, tubona nkubukorikori bwingenzi, budasimburwa.

Igice cya 2: Kubungabunga - Urufunguzo rwo Kuringaniza Kuramba

Isahani ya granite ni igikoresho cyuzuye, ntabwo ari akazi. Bimaze kwemezwa, ubushobozi bwayo bwo kugumana ukuri biterwa ahanini na protocole y'abakoresha n'ibidukikije.

Kugenzura Ibidukikije nicyo kintu kimwe gikomeye kigira ingaruka kuri granite. Mugihe granite ifite coefficente yo kwaguka yubushyuhe (COE), itandukaniro ryubushyuhe hagati yubuso bwo hejuru no hepfo (vertical vertical gradient) birashobora gutuma igisate cyose kiba dome cyangwa cyoroshye. Isahani rero igomba kubikwa kure yizuba ryizuba, imashini itanga ubukonje, nubushyuhe bukabije. Ibidukikije byiza bikomeza 68 ° F ± 1 ° F (20 ℃ ± 0.5 ℃).

Kubyerekeye Gukoresha no Gusukura Porotokole, guhora ukoresha ahantu bitera kwambara kutaringaniye. Kurwanya ibi, turatanga inama yo kuzenguruka icyapa kumwanya wacyo no gukwirakwiza ibikorwa byo gupima hejuru yubutaka bwose. Isuku ya buri munsi ni itegeko. Umukungugu hamwe nimyanda myiza ikora nkibintu byangiza, byihuta kwambara. Gusa hagomba gukoreshwa isuku yihariye ya granite, cyangwa alcool isopropyl. Ntuzigere ukoresha ibikoresho byo murugo cyangwa isuku ishingiye kumazi bishobora gusiga ibisigazwa bifatika cyangwa, mugihe cyamazi, gukonjesha byigihe gito no kugoreka hejuru. Iyo isahani idafite akazi, igomba gutwikirwa igifuniko gisukuye, cyoroshye, kidasebanya.

Hanyuma, kubyerekeye Kwisubiramo no Kuvugurura, nubwo ubyitayeho neza, kwambara byanze bikunze. Ukurikije icyiciro cyo gukoresha (urugero, Icyiciro AA, A, cyangwa B) hamwe nakazi kakazi, isahani ya granite igomba guhindurwa muburyo busanzwe buri mezi 6 kugeza 36. Umutekinisiye wemewe akoresha ibikoresho nka autocollimator cyangwa laser interferometero kugirango ashushanye gutandukana. Niba isahani iguye hanze yurwego rwo kwihanganira, ZHHIMG itanga serivisi zinzobere zo kongera gukora. Iyi nzira ikubiyemo kugarura neza neza kurubuga cyangwa mukigo cyacu kugirango dusubize neza ubwitonzi bwambere bwemewe, usubize neza ubuzima bwigikoresho.

Mugusobanukirwa uburyo bunini bwo gushiraho no kwiyemeza gukora gahunda itajegajega, abayikoresha barashobora kwemeza ko plaque ya granite ikomeza kuba umusingi wizewe kubyo basabwa byose byujuje ubuziranenge, imyaka icumi nyuma yimyaka icumi.
