Udinga izingxenye zensimbi ezinembayo—ngokushesha? Hhayi "ukusheshisa ukusakaza." Imboni yokukhipha imali esheshayo kusho ukuguqula izingxenye eziyinkimbinkimbi, ezinobuqotho obuphezulu njengezindlu zephampu ye-cobalt alloy AMS 5387 kusukela ekudwebeni kuya ekuthunyelweni ngaphansi kwezinsuku ezingama-21. Lokho akukhona ukusheshisa. Ihlela kabusha umugqa wesikhathi.
Sesilethe ama-batch aguquguquka ngokushesha angaphezu kuka-1,200 kusukela ngo-2020—iningi lawo okungamavalvu okucindezelayo, izindlu zesilinda sephampu ye-piston, nama-winch center shaft roller kuma-OEM asebenza ngomshini kulo lonke elaseNyakatho Melika naseYurophu. Okwenza kusebenze akusona isivinini sodwa. Kuyindlela ukusakaza okuqinile, umshini, nokulawula i-metallurgical kukhiya ndawonye.
Iningi lama-Foundries liphatha ukutshala imali njengenqubo ezimele. Bathela amaphethini we-wax, amagobolondo omlilo, ukhonkolo, bese beyiswa esitolo semishini—uma ikhona. Ukubambezeleka kwesitaki: ukuhlela ukwelashwa kokushisa, umshini wokulinganisa wokudidiyela (CMM) ukusilela emuva, izikhala zokulandeleka kwezinto. Sibone iklayenti elilodwa lilinda izinsuku ezingama-47 ukuze liqinisekise ukujiya kodonga kupulaki yamafutha negesi. Ukucaciswa kwabo kudinga ukubekezelela okungu-±0.05 mm engxenyeni ye-cobalt-nickel engu-120 mm ububanzi. Ukubambezeleka akubanga ngenxa yokunensa—kwakusuka ekuhlukaneni.
Isixazululo sethu siqala ngokuhlanganiswa okuqondile—hhayi njenge-buzzword, kodwa njengokuhamba komsebenzi kwansuku zonke. Idizayini yephethini ye-wax yenzeka eduze nokubuyekezwa kwe-GD&T. Isikhathi sokushiswa kwesikhunta seShell siqondana nokutholakala kwesithando somlilo *kanye* nezibikezelo zomthwalo we-CNC spindle. Imijikelezo yokwelashwa kokushisa iqinisekiswa kusengaphambili ebangeni ngalinye le-alloy—AMS 5387, T800, F22 steel—ngakho alikho iqoqo elilinda ukuphrofayela eshisayo. Yonke ingot ye-cobalt alloy engenayo iphethe imibiko yokuhlola egcwele yokugaya; yonke ingxenye eqediwe igcina ukulandeleka kwezinga lelotho phansi enombolweni yeshaja yesithando somlilo.
Lokhu kuqeda amaphuzu amathathu okuhluleka ajwayelekile kumaphrojekthi okusakaza ngokushesha:
- I-Dimensional Drift phakathi kokusakaza nokuqeda imishini-ixazululwe ngokubamba ukubekezelelana okunjengokwe-cast ku-±0.3 mm ebusweni obubucayi, bese kusetshenziswa ukuqinisekiswa kwe-CMM okungaphakathi kwenqubo ngaphambi kokugaya okokugcina
- Ukungahambisani kwe-Microstructure ekubunjweni kwe-alloy ephezulu-kubhekwana namazinga okupholisa alawulwayo ngaphakathi kolayini wethu womlilo oqinisekisiwe we-ISO 9001 kanye nokugawulwa kwemithi ye-thermocouple ngesikhathi sangempela nge-ASTM E2862 ngayinye
- Okumangazayo kokukhubazeka kobuso lapho kuhlolwa okokugcina-kuvinjelwa ukuskena okubonakalayo kwazo zonke isikhunta segobolondo ngaphambi kokuthelwa kanye nemephu ye-porosity ezenzakalelayo ku-100% wezingxenye ze-X-ray
Abanye bangase baphikise ngokuthi ukuhlanganiswa okuqinile kudela ukuguquguquka. Kodwa empeleni, okuphambene kuyiqiniso. Lapho umkhiqizi wephampu waseYurophu edinga ukuphindaphindwa okuyisithupha okubuyekeziwe kwenozi yengxubevange ye-cobalt engajwayelekile—ngalinye lidinga ukulungiswa kwejometri nokuqinisekiswa okubuyekeziwe kwendlela yokugeleza—sasebenzisa ama-prototypes omjikelezo ogcwele ngezinsuku eziyi-11 sisodwa. Kungani? Ngoba onjiniyela bethu baqinisekise ukuthi kungenzeka ukusakaza *ngesikhathi* sokubuyekezwa kwe-CAD—hhayi ngemva kokusikwa kwamathuluzi. Akukho ukudwetshwa kabusha. Azikho izicucu. Ukulungiswa okuphindaphindayo nje ngaphakathi kwesistimu efanayo.
Leyo sistimu ihlanganisa amakhono amane abalulekile asebenza ngaphansi kophahla olulodwa: ukufakwa kwe-investimenti (kumajiyometri ayinkimbinkimbi afika ku-45 kg), ukubunjwa kwesihlabathi (kwezindlu ezinkulu zesakhiwo), umshini we-CNC onama-axis amaningi (ama-axis angu-5 kanyekanye ama-impeller contours), kanye nokuqedwa kwendawo esebenzayo-okuhlanganisa ukumbozwa kwe-HVOF kwezindawo ezigugayo kanye nokuhlanganisa okungaguquki. Konke kulinganiselwe ku-ASME B16.34, ISO 8502-3, kanye nezinqubo zokuhlola zokuvuza eziqondene nekhasimende.
Lokho amakhasimende akubuzayo ngempela—futhi esiphendula ngakho kuqala—akukona ukuthi “Kushesha kangakanani?” Ithi "Ungakwazi ukubamba u-0.002" kulesi sibhobo ngenkathi ugcina ubuqotho bokugeleza kokusanhlamvu ku-fillet?" Noma “Ingabe le pulaki ye-T800 alloy izosinda ngokulayishwa kwe-psi cyclic engu-15,000 ngaphandle kokuqaliswa kwe-microcrack?” Noma “Ingabe unabo ubufakazi obubhaliwe bokuthi iqoqo lakho le-AMS 5387 lihlangabezana nezimfuneko ze-AMS 2301 eziqinile nomthelela?” Senza njalo. Njalo.
Ukusebenza kokulethwa komhlaba wangempela kuyakuqinisekisa: 94.7% wama-oda evolumu emaphakathi (ama-50–500 ama-pcs) athunyelwa phakathi kwezinsuku ezingu-±2 zedethi yokuzibophezela. Izikhathi zokuhola ze-prototype ziyisilinganiso sezinsuku eziyi-14 ukusuka kumdwebo ogunyaziwe ukuya ekuhanjisweni kwe-athikili yokuqala—nombiko ogcwele wobukhulu, izitifiketi zezinto ezibonakalayo, namarekhodi e-NDT afakiwe. Azikho izengezo. Akukho okuhlukile.
Uma ubheka phambili, ibhodlela akuwona umthamo-ukufaneleka. Imikhakha eminingi ifuna izitifiketi ze-EN 10204 3.2, ukuthobela kwe-PED 2014/68/EU, noma ukuqondanisa kwe-API Q1. Ngakho-ke sandisa ububanzi bokuhlola bethu benkampani yangaphandle kanye nokuqinisekiswa kwenqubo ye-hybrid yokwakha amahybrids akhiwe ngomshini—njengamavalvu ahlanganisiwe lapho indandatho yesihlalo ifakwa khona utshalomali *esendaweni*, bese igqitshwa ukuze ifane ne-stem bore.
Uma iphrojekthi yakho elandelayo idinga izingxenye zensimbi ezinembayo—hhayi nje ukulingwa, hhayi nje izingxenye eziwumshini, kodwa izingxenye ezisebenzayo ezihlanganisiwe ezakhelwe ukusebenza ngaphansi kwengcindezi—khona-ke udinga okungaphezu kwesakhiwo esiyisisekelo noma isitolo semishini. Udinga a imboni yokukhipha imali esheshayo lapho kuhlangana khona i-metallurgy, i-geometry, nohlelo. Hhayi njengesethembiso. Njengomkhuba ojwayelekile.
