Lapho onjiniyela becacisa a ukunemba ekubunjweni kwemboni, abagcini ngoku-oda izingxenye zensimbi—bazibophezela ekuzinzeni kobukhulu ngaphansi kwemithwalo ye-hydraulic engu-120 MPa, ukungaguquguquki kwe-microstructural kuwo wonke amaqoqo angamayunithi angu-500, kanye nokungabekezeleli i-porosity kumabhobho e-cobalt-alloy. Lelo iqiniso esibhekana nalo nsuku zonke e-Qingdao Qiangsenyuan Technology Co., Ltd.-isikhungo lapho ukutshala izimali kungesona isinyathelo senqubo; kuyisisekelo sokuthembeka kokusebenza.
Sibone amaphrojekthi amaningi kakhulu emiswa esigabeni se-prototype ngoba umsunguli uphathe ingxubevange ye-cobalt ye-AMS 5387 njenge-316 ejwayelekile. Iphampu eyodwa yaseNyakatho Melika i-OEM isithumelele umdwebo we-GD&T onokubekezelela indawo okungu-±0.015 mm endlini yesilinda yephampu yepiston engu-220 mm-diameter—futhi yahamba ngemva kokuthi iqembu lethu lihlabe umkhosi ngoshintsho olubalulekile lokujiya kodonga olungabamba ukushwabana ezibunjeni zesihlabathi. Leyo ngxoxo yashintsha indlela esihlela ngayo izibuyekezo zobunjiniyela: manje, konke ukuqinisekiswa kwemidwebo kufaka ukumbondelana kokulingisa kwe-thermal-mass, hhayi nje ukuhlola ubukhulu.
Unqenqema lwethu lobuchwepheshe luqala ngesiyalo sezinto ezibonakalayo. “Asiwasebenzisi” ama-cobalt-nickel alloys—siyawafaneleka. Yonke i-billet esekelwe ku-T800 ifika nemibiko egcwele eqinisekisiwe ngokushisisa elandelelwa ku-ASTM A992 kanye ne-AMS 5387 Rev. D. Lapho ikhasimende lase-Europe lifuna amarola aphakathi nendawo angajwayelekile ama-winch system asogwini lolwandle, sihlanganise isistimu yokugenca yangokwezifiso nomnikezeli wethu wezinto ezibonakalayo ukuze kucindezelwe ukuhlukaniswa kwe-dendritic ku-20mm-thick20. Umphumela? Isivuno sibe ngcono sisuka ku-63% saya ku-91% ngaphandle kokudela ubulukhuni be-Rockwell C45–48. Lokhu akuyona i-metallurgy ecatshangwayo—ukulawulwa kwenqubo okuphindaphindwayo okubhakwe ekugelezeni komsebenzi okuqinisekisiwe kwe-ISO 9001:2015.
- Ukuhlanganiswa okuqondile okubalulekile: Ukusakaza, ukwenziwa kwemishini ye-CNC ye-multi-axis (kufika ku-5-eksisi kanyekanye), futhi ukuqedwa kokugcina kwendawo kwenzeka ngaphansi kophahla olulodwa—akukho ma-handoffs, akukho ukungahambi kahle kwesistimu ye-coordinate, akukho ukuhluka kokuqedwa kwe-batch-to-batch
- Ukuphoqelelwa kobukhulu, hhayi ukuhlola: Ama-CMM asebenzisa izindlela ezizenzakalelayo ze-GD&T ku-100% wezici ezibalulekile; ama-profilometer okubona aqinisekisa i-Ra ≤ 0.4 µm endaweni evalekayo ngaphambi kokwelashwa kokushisa
- Ukwesekwa komklamo wokuqala: Siyazenqaba izicelo zokuthi “vele uzenze”. Esikhundleni salokho, senza imephu yezindlela zokucindezelwa emizimbeni yamavalvu okucindezela, silingise ukuhamba ngebhayisikili okushisayo ezisekelweni zephampu, kanye nama-engeli angakapheli ahlaba umkhosi abeka engcupheni impilo yokukhathala—ngisho noma kusho ukubuyela emuva ku-RFQ.
Abanye bangase baphikise ngokuthi ukukhishwa kwe-outsourcing kuma-Foundries akhethekile kwehlisa izindleko. Kodwa uma indlu yakho yephampu yepiston kufanele igcine ukugxila phakathi kwezindawo zokubhoboza ne-flange phakathi kuka-0.02 mm ngemva kokucisha, noma lapho ipulaki ye-cobalt-alloy idinga i-zero voids yangaphakathi ekukhulisweni okungu-3×, amaketanga okunikezela ahlukene ethula ingozi engamukeleki. Silandele umsuka wezimbangela zokwehluleka kuzo zonke izingxenye ezithunyelwe ezingu-1,200+: 78% wokuchezuka kobukhulu basuka ekwandeni kwesikhunta esingalawuleki phakathi nemijikelezo yokushisa kwangaphambili—hhayi iphutha lomshini. Yingakho imigqa yethu yokusakaza isihlabathi isebenzisa ukuqapha kwezinga lokushisa kwebhokisi lesikhathi sangempela, futhi kungani utshalomali lwethu lwe-autoclaves lwe-autoclaves lufinyelela ku-0.1°C/sec.
Yini ehlukanisa iqiniso ukunemba ekubunjweni kwemboni kusuka kumsunguli ojwayelekile? Yindlela ophatha ngayo ama-outliers. I-geometry engajwayelekile. I-engeli ye-helix engu-17.3° ku-winch center shaft roller. Umbhobho we-AMS 5387 odinga ubuyindilinga obungu-0.008 mm ngaphezu kobude obungama-85 mm. Lokhu akukhona okuhlukile—ngamaphuzu ethu okulinganisa. Yonke ingxenye ithunyelwa ngokulandeleka okugcwele: inombolo encibilikayo, inkatho yokusakaza, i-ID yomjikelezo wokuphatha ukushisa, isitembu sesikhathi sombiko we-CMM, nesitifiketi sika-opharetha. Akukho okuhlukile. Akukho ukuyekwa.
Uma ucacisa izingxenye zensimbi ezibekezelela kakhulu amasistimu asebenza ngamanzi, amavalvu e-oilfield, noma ama-heavy-duty pump asembles, funa ubufakazi—hhayi izincwajana. Cela ama-micrographs ahlukene ku-oda lakho lokugcina. Cela umbiko wangempela we-CMM wesici ngokubekezelela okuqinile. Qinisekisa ukuthi izitifiketi zezinto ezibonakalayo zifana nenombolo yokushisa egxivizwe engxenyeni. E-Qingdao Qiangsenyuan, lawo madokhumenti awagcinwanga kungobo yomlando—ngawokuqala alethwa kukho konke ukuqaliswa kwephrojekthi.
Ikusasa lokulingisa ngokunemba akuzona iziko ezinkulu noma ama-spindle e-CNC asheshayo. Kuqina ukuhlanganiswa phakathi kwemodeli yokuqinisa kanye nezindlela zomshini ezishayelwa yi-GD&T. Kuyisibikezelo se-porosity esisizwa yi-AI esiqeqeshwe ezithombeni ze-X-ray ezingu-12,000+. Ubambiswano lwe-R&D oluphusha ama-cobalt-nickel alloys ngaphezu kwemikhawulo yamanje yokukhuphuka. Sakha lelo khono manje—hhayi njengesithembiso sokumaketha, kodwa njengesethi elandelayo yokulawula inqubo esitezi sesitolo sethu.
