Lapho onjiniyela baseNyakatho Melika noma eYurophu bedinga a China CNC ukunemba machining ifektri ekwazi ukubamba ukubekezelela okungu-±0.005 mm ezindlini zephampu ye-cobalt-nickel - ngaphansi kokulandeleka okugcwele kanye nokuhlolwa okuthobela i-ISO - abamane nje bafune "umphakeli we-CNC e-China." Basesha *amandla afakazelwe*, hhayi izithembiso zekhathalogi.
Sibone amaphrojekthi amaningi kakhulu efa esiteji sesibonelo ngenxa yokuthi isitolo samukele umdwebo kodwa sintula ulwazi ngokuziphatha kokuqina komsebenzi kwe-AMS 5387 ngesikhathi sokugaya ama-axis amaningi. Noma okubi kakhulu: yamukelwe izingxenye zengxubevange ye-T800 ngaphandle kokuqinisekisa imibiko yensimbi yezinga lenqwaba evela kubahlinzeki abaqinisekisiwe. Ukunemba kobukhulu akusho lutho uma ubuqotho besakhiwo se-microstructure kwehluleka ngaphansi kokuhamba ngebhayisikili ka-hydraulic wamabha angu-300. Kungakho ukuthembeka kokusebenza - hhayi nje ukuthobela i-GD&T - kuhlukanisa iqiniso China CNC ukunemba machining ifektri kusuka esitolo semisebenzi ejwayelekile.
Ukunemba komhlaba wangempela kuqala ngesiyalo esibalulekile - hhayi nje imininingwane yomshini
Ama-alloys asekelwe ku-cobalt afana ne-T800 ne-AMS 5387 "ayenziwe ngomshini" - ayakhohliswa. Ukusebenza kwawo okushisayo kungu-1/10 we-aluminium. Ukukhishwa kwe-chip akuphumelelanga uma amazinga okuphakelayo ekhukhuleka ngo-3%. Ukushisa okukodwa okungaqinisekisiwe kungashintsha ubulukhuni ngo-15 HRC - okwanele ukuqhekeza isihlalo somlomo ngesikhathi sokuhlolwa kwengcindezi.
I-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphatha impahla eluhlaza njengesinyathelo sokuqala senqubo — hhayi ibhokisi lokuhlola lokuthenga. Yonke i-cobalt-nickel billet iphethe izitifiketi ezigcwele zokugaya, eziqinisekiswa lapho ifika ngokumelene ne-ASTM A494 ne-AMS 5719. Ithimba labo lezobuchwepheshe lifanelekela umhlinzeki ngamunye, lihlola amalogi eziko kanye nemibiko ye-spectrographic — hhayi nje ama-invoyisi. Lokhu akukona ukudlula ngokweqile. Kuyindlela abaletha ngayo isivuno sokuqala esingu-99.2% kuma-rotor futha we-AMS 5387, ngisho nalapho ukujiya kodonga kwehla ngaphansi kuka-2.3 mm.
Ukuhlanganiswa kwabo komshini wokulingisa kuqinisa ukulawula lapho abanye belahlekelwa khona. Izisekelo zephampu yensimbi esakazwa ngesanti zifika sezifakwe imishini kusengaphambili ukuze zibe ±0.1 mm isitokwe esimaholoholo — sisusa amaphutha okulungisa kabusha. Imibhobho ye-cobalt ye-investimenti iqonda ngqo ku-CNC ye-axis engu-5 ukuze uthole amakhonsathi okugcina, eqa ukwelashwa kokushisa kwesibili okusonta amajiyometri anezindonga ezincane. Ukuhlanganiswa okuqondile akumayelana nokonga izindleko. Imayelana nokuvala ukuzinza kwe-dimensional kuyo yonke imijikelezo yokushisa.
Ukuhlola akulona isango lokugcina - kushunyekwe kukho konke ukunyakaza kwe-eksisi
Izitolo eziningi zisebenzisa amasheke e-CMM ngemuva komshini. I-QINGDAO QIANGSENYUAN iwaqhuba *ngesikhathi* — phakathi kwamaphasi amabi nokuqeda. Kungani? Ngenxa yokuthi ithuluzi elingu-0.012 mm liguga i-offset ku-piston pump cylinder housing lishintsha libe ne-taper elingaphezu kwemingcele yokusebenza. Ama-profilometer abonayo alinganisa ukuqedwa kwendawo *in situ*, enqaba izingxenye ngaphambi kokuba into epholile igeze ubufakazi bokudabuka okuncane.
Yonke ingxenye ebalulekile ithola ukulandeleka okugcwele: inombolo yokushisa, i-ID yomsebenzisi, i-ID yomshini, isitembu sesikhathi sombiko we-CMM, nokuphuma kokugcina okubonakalayo kophawu uma kuqhathaniswa nemibandela yokwamukela echazwe yikhasimende — hhayi i-“ISO 2768” ejwayelekile. Lapho i-OEM yaseYurophu icela ukuqinisekiswa kokusebenza kwerola ye-winch centre shaft engajwayelekile ngaphansi komthwalo ofanisiwe, ithimba lakha ijigi yokuhlola yangokwezifiso futhi laletha amajika e-torque-deformation eduze kokuthunyelwa. Akukho ukucaphuna okwengeziwe. Akukho ukubambezeleka. Ukuqondanisa ubunjiniyela nje.
Idizayini yokukhiqiza ayiyona indatshana yokuthengisa - ukunciphisa ubungozi bokuqala kwephrojekthi yakho
“Ungakwenza lokhu?” umbuzo ongalungile. Okulungile ukuthi: "Yini ezohluleka kuqala - i-geometry, i-material, noma i-process chain?"
Onjiniyela be-QINGDAO QIANGSENYUAN bahlaba umkhosi ngezinkinga ngaphambi kokusika insimbi. Bazobiza izingxabano ze-GD&T lapho ukubekezelelana kwezikhundla kungqubuzana nama-engeli asakazwayo. Bazophakamisa ukulungiswa kwerediyasi okuncane kupulaki ye-cobalt ukugwema imifantu emincane ebangelwa ingxoxo. Bayenqaba imidwebo enezimbobo ezingabonakali zangaphakathi - bese bephakamisa enye indlela esebenzayo enomthelela wesikhathi somjikelezo obhaliwe.
Lokhu akuyona i-nitpicking. Kuyindlela abasika ngayo izilinganiso zesikhathi ze-NPI (isingeniso somkhiqizo omusha) ngo-37% kuma-valve ama-hydraulic valve. Impendulo yangaphambi kwesikhathi ivimbela u-$12,000 kumabhilidi e-T800 alahliwe - kanye namaviki amathathu okusebenza kabusha.
Uma ubheka phambili, ukugxila kwabo kwe-R&D akukhona emishinini emikhulu. Isezinkambweni eziyingxubevange: ukusakazwa kokutshalwa kwezimali komumo oseduze nenetha okunamashaneli okupholisa ahlanganisiwe, kuqedwe ngokugaya okuphakelayo okuphezulu okulondoloza ingcindezi eyinsalela. Okuhloswe ukunwetshwa kwesitifiketi ku-API 6A kanye ne-PED 2014/68/EU — hhayi njengamabhokisi okuhlola, kodwa njengemingcele yedizayini efakwe kusofthiwe yabo yokuhlela inqubo.
Uma ingxenye yakho elandelayo yokubekezelela kufanele ikwazi ukumelana nengcindezi ephezulu, ukugqoka okuphezulu, noma ukugqwala okukhulu - futhi udinga China CNC ukunemba machining ifektri ephatha i-metallurgy njengento ebalulekile njengomshini - qala ngokulandeleka kwezinto, hhayi ama-MOQ kuphela. Funa ubufakazi bokuhlolwa okungaphakathi kwenqubo — hhayi imibiko yokugcina kuphela. Khetha ozakwethu abakhuluma ulimi lwakho olusebenzayo: izinga lokugeleza, impilo yomjikelezo, imodi yokwehluleka — hhayi nje ama-microns kanye namanani e-Ra.
Ukunemba kweqiniso akukalwa ekupheleni komugqa. Yakhelwe kuzo zonke izinqumo - kusukela ekukhetheni indawo yokushisa kuya kuqhinga lendlela yamathuluzi. Yilapho ubunjiniyela buhlangana khona nokwenziwa.
