Gushakisha a gutunganya neza hafi yuruganda itanga ibice-byingenzi-ntabwo ari kwihanganira gusa, ahubwo ni ikizere? Ntabwo urimo gushakisha iduka "ryose". Ukeneye imwe ikora AMS 5387 cobalt alloy nozzles idafite ibisigazwa, ifata mm 0.005 mm kumazu ya pisitori ya pompe ya pisitori munsi yamagare yumuriro, kandi ugakurikirana buri cyiciro cyibikoresho bya T800 ugasubira mububiko bwacyo. Ibyo ntabwo ari imyitozo isanzwe. Yinjije.
Iyo "Hafi yanjye" bivuze "Kumenya gusaba kwawe"
"Gutunganya neza neza hafi yuruganda" bikunze kwandikwa byihutirwa-nyuma yuko uwabitanze abuze kubitanga, akanga guhamagarwa kwa GD&T, cyangwa kohereza inzu yumuvuduko wamazu ufite micro-crack itagaragara mumaso ariko ibiza munsi yumubari 350. Twabibonye: hydraulic yo muri Amerika ya ruguru OEM ikora 12% ya casting yinjira kuko iduka ryabo ryabuze kugenzura umucanga. Undi mukiriya yakuyeho prototype eshatu za winch center shaft rollers - buri kimwe kigura amadolari 2,400 - kubera ko ubusugire bwananiwe kwipimisha umunyu. Ntabwo ari amakosa yo gutunganya. Nibyuho bya sisitemu: ntakintu gishobora gukurikiranwa, nta cyemezo cyo kuvura ubushyuhe, nta CMM yagenzuwe na GD&T ihuza casting datum nibintu byanyuma byakozwe.
Niyo mpamvu kuba hafi yonyine bidakemura kwizerwa. Icyangombwa ni * inzira yegeranye *: guta, kuvura ubushyuhe, imirongo myinshi ya CNC, hamwe na metero munsi yinzu imwe yujuje ISO-hamwe naba injeniyeri bahinduye injeniyeri 17 zitandukanye za AMS 5387 pompe yimiryango. Ntabwo ubumenyi bwubumenyi. Ubushobozi bwagaragaye mu murima muguhindura, gusya, no gusya cobalt-nikel ivanze aho ubuzima bwibikoresho bugabanuka 60% mugihe ubukonje bukonje buhindutse kuri 0.3%.
Ubushobozi bune burinda rwose gutsindwa
Amaduka menshi yanditse urutonde rwa "CNC mashini" na "casting." Bake babihuza bihagije kugirango bemeze ituze ryikigereranyo cyizuba. Dore icyimura urushinge:
- Kwishyira hamwe guhagaritse kuva gushonga kugeza birangiye. Nta ntoki. Nta mibare yatakaye.
- Cobalt-alloy yihariye - ntabwo ari ubushobozi gusa: Ibikoresho byabigenewe, imirongo ikonjesha ya kirogenike, hamwe na spindle vibration igabanuka kuri AMS 5387 na T800. Ntabwo "tugerageza" ibi bikoresho. Dukurikirana imyenda ya karbide kuri santimetero kibe yakuweho - kandi tugahindura igipimo cyibiryo mugihe nyacyo dukoresheje ibyuma byifashishwa.
- Kugenzura nkumufatanyabikorwa: Umuvuduko wose wumuvuduko utangirana no gushushanya kwemeza - ntabwo "dushobora kubikora?" ariko "iyi geometrie izarokoka umuvuduko w'ingutu 10,000 utanyeganyega ku ntebe y'intebe?" Raporo zacu za CMM zirimo isesengura rya GD&T, ntabwo ari pass / gutsindwa gusa.
- Indero y'ibikoresho, ntabwo ari icyemezo gusa: Ububiko bubi ntabwo "byemewe kuri ASTM A494." Turagenzura ingano yingano, gukwirakwiza icyiciro cya intermetallic, hamwe nuburinganire buringaniye kubice byambukiranya-kuko ikizamini cya 3 cya Brinell hejuru ntigishobora gufata amacakubiri yo munsi yubutaka bwa pompe yuburebure bwa mm-120.
Kuki "Yizewe" Itangira Kera Mbere yo Gukata bwa mbere
Abacuruzi bamwe basezeranya amagambo yihuse. Twohereje ibitekerezo byubwubatsi mumasaha 48 - harimo inoti zishobora gukorwa nka: "Iyi radiyo 0,12-mm ya radiyo kuruhande rwicyambu cya valve izacika mugihe cyo kubaha. Saba byibuze 0,25-mm, cyangwa uhindure amashanyarazi." Ibyo ntabwo ari ugusubira inyuma. Nukugabanya ingaruka wakura mumakipe y'imbere.
Twohereje ibice birenga 8.200 byabigenewe kubakiriya mubudage, Kanada, na Singapuru - byose bifite ibikoresho byuzuye, inyandiko zivura ubushyuhe, na raporo yubugenzuzi bwingingo ya mbere yashyizweho kashe na laboratoire yabandi. Nta na kimwe kidasanzwe. Iyo umuterankunga wa pompe yo mu majyepfo y’iburasirazuba bwa Aziya yari akeneye ibyuma 47 bidasanzwe bya cobalt alloy mu minsi 11, twahinduye ahantu hacanwa itanura ry’ubushyuhe, dukora metero nijoro, hanyuma dutanga amakuru ya CMM yemewe yerekana diameter zose zikomeye muri mm 0.003 mm. Ntabwo ari “hafi yanjye.” Hafi yigihe ntarengwa. Hafi yicyerekezo cyawe. Hafi yuburyo bwawe bwo gutsindwa.
Intambwe Zikurikira: Niki Kubaza Umufatanyabikorwa wawe Ukurikira
Ntubaze “Ukora CNC?” Baza:
- "Nyereka raporo zawe eshatu zanyuma za CMM kubice bya cobalt-alloy-cyane cyane uburyo wagenzuye neza ukuri kwimiterere yibintu ugereranije no guta datum."
- "Nigute ushobora kwemeza ubushyuhe bwumuriro wibikoresho byawe? Wandika ubushyuhe bwubushyuhe kuri buri suka, cyangwa wishingikirije kugenzura?"
- "Ni ikihe kigereranyo cyawe cyo guhindura ibikoresho mugihe utunganya AMS 5387 kuri 45 m / min? Kandi ni gute ushobora kwishyura indishyi zo kwambara mu burebure bwa Z-axis?"
Niba ibisubizo bidasobanutse - cyangwa bibi, rusange - urimo kuvugana numucuruzi, ntabwo ari umufatanyabikorwa. Gutunganya neza kwizerwa ntabwo bijyanye nahantu. Byerekeranye no kugenzura inyandiko, guhamya metallurgjiya yemejwe, hamwe nubushake bwo kuvuga "oya" ku gishushanyo kizananirwa muri serivisi.
Kuri ba injeniyeri bagaragaza ububiko bwumuvuduko, inzu ya silinderi, cyangwa ibice byambaye imyenda myinshi: tangira usubiramo tekiniki - ntabwo ari amagambo yatanzwe. Kuberako ibyiza gutunganya neza hafi yuruganda ntabwo iboneka ku ikarita. Byemejwe mu makuru.
