Lapho onjiniyela becacisa izingxenye zamaphampu asebenza ngogesi, amavalvu angasogwini, noma amasistimu ewintshi asindayo, abadingi nje “insimbi engumshini.” Badinga ukuzinza kwe-dimensional ngaphansi kwengcindezi yamabha angu-300. Badinga imibhobho ye-cobalt alloy ekwazi ukumelana ne-galling ku-650°C. Badinga izindlu zabalingisi lapho ubuqotho besakhiwo esincane bufana nama-callouts e-GD&T—kuze kufike ku-±0.01 mm. Kungakho ama-OEMs omhlaba kanye nabahlinzeki be-Tier-1 bebuyela njalo ku-a uNdunankulu ukunemba machining ifektri ayigxilile ezimangalweni zokumaketha—kodwa ekulawuleni inqubo ephindaphindwayo, isiyalo se-metallurgical, kanye nokuhlolwa kwe-zero-compromise.
Ukubekezelelana komhlaba wangempela kudinga ukukhetha kwangempela kokukhiqiza
Sibone amaphrojekthi amaningi kakhulu esima esigabeni se-prototype—hhayi ekwakhiweni okunephutha, kodwa emandleni angafani. Iklayenti lake lasithumelela umdwebo wezindlu wephampu we-AMS 5387 okwazi ukubekezelela isimo sangempela esingu-Ø0.015 mm kumabhore ayisishiyagalombili abalulekile. Umhlinzeki wabo wangaphambilini wayicaphuna njenge-“CNC-machinable,” wabe eseletha izinkatho ezintathu ezilandelanayo ngokuchezuka okungu-0.032 mm endaweni yophawu lwangemuva. Kungani? Ngoba CNC'd i-sand-cast engenalutho ngaphandle kokudambisa ingcindezi kuqala-futhi ayizange ilinganise ukukhukhuleka okushisayo ngesikhathi sokudlula amahora amaningi. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., siphatha yonke imakron njengemfuneko yokusebenza, hhayi umbhalo waphansi wencazelo. Indawo yethu ethobela i-ISO e-Qingdao ihlanganisa ukusakaza, ukwelashwa kokushisa, kanye nemishini ye-axis engu-5 ngaphansi kophahla olulodwa—hhayi ukuze kube lula, kodwa ukukhiya inkumbulo enobukhulu kuyo yonke imingcele yenqubo. Lapho ufaka ipulaki ye-T800 ye-cobalt alloy ngemva kokutshala imali, ukucindezeleka okusalayo akulona inkolelo-mbono. Yilokho okushintsha i-axis yakho yokugcina ngo-0.008 mm. Siyimephu. Siyayikhulula. Siyakuqinisekisa—ngaphambi kokusika kokuqala.
Akuzona zonke izitolo "ze-high-alloy" eziphatha ama-superalloy ngendlela efanayo
Abanye abakhiqizi babhala “ama-cobalt-nickel alloys” kukhathalogi yabo bese bema lapho. Kodwa okuhlangenwe nakho kuyasitshela: I-AMS 5387 ayisebenzi njenge-Inconel 718 lapho igaya imibhobho enezindonga ezincane. Izinga layo lokuqinisa umsebenzi liyakhuphuka ngemva kokujula okungu-0.15 mm kokusikwa. I-thermal conductivity yayo iyingxenye yensimbi engagqwali—ngakho ukuphila kwamathuluzi kuyehla uma ukugeleza kokupholisa kwehla ngaphansi kuka-45 L/min ngo-12,000 rpm. Sisebenzisa ukuqapha okukhethekile kwe-spindle emishinini yethu ye-Mazak INTEGREX i-200S—hhayi ukuze sijahe amamethrikhi esikhathi esengeziwe, kodwa ukuze sithole amaphethini ezingxoxo ezincane ezandulela ukuwohloka kwendawo. Sibamba kanjalo-ke u-Ra ≤ 0.4 µm kumadayamitha angaphakathi ezihlalo zamavalvu e-cobalt alloy, ngisho nasezilinganisweni ezingu-120 mm ubude nobubanzi. Futhi yebo-siqinisekisa yonke inkatho ngokumelene nosayizi wokusanhlamvu we-ASTM E112, ngokwesicelo sekhasimende ngalinye. Akukho ukucabanga. Azikho izinqamuleli.
Ukuhlanganiswa okuqondile kusho ukunikezwa okuncane—kanye namaphoyinti okuhluleka ambalwa
Cabanga ngomzimba we-valve yokucindezela: insimbi eyi-ductile iron (ASTM A), ifakwe ukushisa ibe ngu-28–32 HRC, bese ifakwa ngomshini ngezindawo zokuvala eziyisithupha, izimbobo ezinezintambo ezinezintambo, namabhore amabili afaka ukucindezela—konke kungaphakathi kuka-±0.012 mm inani eliphelele. Uma ukusakaza, ukwelapha ukushisa, kanye nokwenza imishini kwenzeka kubathengisi abahlukene, ubani ongumnikazi wephutha lesitaki lapho ukuhlangana kokugcina kuvuza kubha engu-250? Kwa-QINGDAO QIANGSENYUAN, ithimba lonjiniyela elilodwa lengamele ukulandelana okugcwele. Isikhungo sethu sisebenzisa ukuqinisekiswa kwenqwaba ye-spectrometric ngaphambi kokuthulula. Amahhavini ethu okushisa afaka amaphrofayli wesikhathi sezinga lokushisa ngomthwalo ngamunye—hhayi ngokushintshana ngakunye. Ilebhu yethu ye-CMM isebenzisa ukulinganisa okuthobela i-ASME B89.1.10M nsuku zonke, futhi ingxenye ngayinye ithola ukuhlolwa okugcwele kwejiyomethri—hhayi nje ukuhlola amabala. Ukulandeleka akuwona umbiko; ikhodi ye-QR efakwe engxenyeni ngayinye exhumanisa emuva kukhemistri encibilikayo, i-ID yokuhlola ubulukhuni, kanye nomsebenzisi osayine lapho kuhlolwa okokugcina okubonakalayo.
Lena yindlela izingxenye ezibalulekile zemishini ezizuza ngayo ukwethenjwa—hhayi nje ukulethwa
Amakhasimende ethu awasikhetheli ngentengo ephansi. Bayasikhetha ngoba lapho i-OEM yephampu yaseYurophu idinga izindlu ezingamasilinda ezingajwayelekile ezingama-47 ukuze kwenziwe ukuhlola kwe-subsea—futhi idinga izitifiketi zezinto ezibonakalayo ezigcwele, imibiko ye-NDT, nedatha yokuhlola yokusebenza phakathi kwezinsuku eziyi-18—babazi ukweqa ukubuyekezwa “kokuklanywa kokwenziwa” kuzobiza ngaphezu kwekhowuthi. Ngakho-ke sisebenzise ukuqinisekiswa kwe-GD&T ngaphambi kokucaphuna. Ihlatshwe umkhosi ukubekezelelwa kwephrofayela okubili okungahambelani nokusetshenziswa kwamathuluzi okujwayelekile. Kuhlongozwe uhlelo lwedatha olubuyekeziwe olubambe ukusebenza ngenkathi lusikwa isikhathi somjikelezo ngama-22%. Kulethwe ngeshejuli—nabo bonke ubukhulu buqinisekisiwe, yonke indawo engaphezulu iqinisekisiwe, futhi lonke ijika lokuphatha ukushisa lifakwe kungobo yomlando. Lokho kuyisigqi sokusebenza seqiniso uNdunankulu ukunemba machining ifektri: ukubonisana kwezobuchwepheshe okwakhelwe ekuhambeni komsebenzi, akungezwe njengokucatshangelwa kwamuva.
Uma ubheka phambili, isidingo akusona “esokwenza imishini eyengeziwe”—ngezinqubo zenhlanganisela ehlakaniphile. Ukutshala imali kanye nokunemba kwe-EDM yokumba amashaneli okupholisa kuma-rotor wepompo anomfutho ophezulu. Ukulingisa kwesihlabathi ngama-thermocouples ashumekiwe ukuze kumephu ukuqina ngesikhathi sangempela. I-R&D ayiyona into engabonakali lapha—ilinganiswa ngezilinganiso ezincishisiwe ze-scrap, amanani aqinile we-Cpk ezicini ezibucayi, nemijikelezo yokufaneleka esheshayo yama-alloys ebanga le-aerospace. Uma iphrojekthi yakho elandelayo incike ekuphindaphindeni-hhayi inkulumo-nkulumo-qala ngenqubo esobala, hhayi izithembiso zencwajana. Izingxenye ngeke ziqambe amanga. Nathi asikwenzi lokho.
