Lapho onjiniyela becacisa a imboni elahlekile yokuphonsa ingcina, abagcini ngoku-oda insimbi kuphela—bafuna ukuphindaphindeka kobukhulu obungaphansi kuka-0.02 mm, ukungaguquguquki kwe-microstructural kuwo wonke amaphampu e-cobalt alloy engu-100 kg, kanye nokungabekezeleli i-porosity emizimbeni yamavalvu anomfutho ophezulu. Sibone amakhasimende ebuyisela imizuliswano emithathu yamabhomu e-AMS 5387—ukuthola kuphela umsuka bekungewona umshini, kodwa ukwakheka okusanhlamvu okugayiwe kwangaphambili okungahambisani okuvela endaweni etholakala phezulu nomfula. Yingakho ukutshala izimali ngokunemba akukona nje "ukwenza isikhunta." Imayelana nokulawula konke okuguquguqukayo: izinga lokushwabana kwephethini yewax, ukukwazi ukungena kwegobolondo le-ceramic, isivinini serempu ephuma ewaxing, isikhathi sokuthulula esisizwa ngevacuum, kanye nokufana kokucwiliswa kokushisa kwangemuva kokusakazwa.
Kungani Ukulahleka Kwe-Wax Kusawina Ezingxenyeni Zezimboni Ezibalulekile Zemishini
Ukulahlwa kwe-wax okulahlekile—okubuye kubizwe ngokuthi i-investment casting—kuletha inkimbinkimbi yokwakheka kwenetha akukho ukulingisa kwesihlabathi noma ukufojiswa okungafaniswa. Kodwa akuwona wonke amafekthri awenza ngokwethembeka esikalini sezimboni. Umehluko ulele ekuqondiseni inqubo, hhayi nje imishini. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha ingxenye ngayinye ye-cobalt-nickel njengokungathi izolawula ukugeleza kwe-hydraulic yamabha angu-350 endaweni yokumba yasogwini. Lokho kusho ukulandeleka okugcwele okuvela kusitifiketi se-T800 alloy billet (ASTM B575) ngokusebenzisa amagobolondo okudubula amajika alogwe ngeqeqebana ngalinye. Silinganisele ukufika ku-12% we-dimensional drift ezindlini zamasilinda lapho izinga lokushisa le-dewaxing lihluka ngo-±5°C—ngakho manje sesiyilawula phakathi kuka-±1.5°C. Amakhasimende eqa ukulandelela inkatho yempahla ngokuvamile athola imifantu yokukhathala evela ngemva kwamahora okusebenza angu-4,200—hhayi phakathi nokuhlolwa kokufaneleka.
Lapho Izimboni Eziningi Zehluleka—nokuthi Ukuhlanganisa Okuqondile Kukulungisa Kanjani
Abanye abahlinzeki bakhipha imithombo yokusakaza, ukwenza imishini, nokuqedela ukuze bahlukanise abathengisi. Lokho kudala amaphuzu amathathu okuhluleka: ukuhumusha okungafani kwe-GD&T phakathi kwe-Foundry kanye nesitolo se-CNC, ukungezwani kokuqedwa kwengaphezulu okufihla ukonakala okungaphansi komhlaba, kanye nokuhlanekezela okushisayo ngesikhathi sokwelashwa kokushisa ngenxa yokungaxhumanisani. I-QINGDAO QIANGSENYUAN TECHNOLOGY iphethe uchungechunge oluphelele—kusuka ekulungiseni igobolondo le-ceramic kuya ekugayweni kwe-multi-axis kwamazinyo egiya angaphakathi ngaphakathi kwezindlu zephampu yepiston. Lapho iklayenti lase-Europe lidinga i-winch center shaft roller engajwayelekile ene-0.015-mm roundness tolerance ku-320-mm OD, sigweme amaviki angu-3 ukuya phambili naphambili ngokusebenzisa izikena ze-CMM ze-athikili yokuqala *ngaphambi* kokutubeka kokugcina kwamagobolondo. Umphumela: izinga lokuphasa lokuqala leqe lisuka ku-68% laya ku-97%. Izibani eziyinhloko? Iziqhathaniso zangaphakathi zasendlini zokuqinisekiswa kwephethini ye-wax, ukuhlolwa kokuqina kokuqina okugunyazwe yi-ISO 17025, kanye nesithombe sesikhathi sangempela esishisayo ngesikhathi sokufakwa kwesixazululo.
Lokho Okutholayo Empeleni—Hhayi Lokho Okuthenjisiwe Kuphela
Buza noma yimuphi umphathi wokuthenga: “ukuqinisekiswa” akusho “ukuqinisekiswa.” I-QINGDAO QIANGSENYUAN TECHNOLOGY ikhipha imibiko yokuhlolwa kwezinto eziphelele (ama-MTR) ngakho konke ukuthunyelwa—okuhlanganisa amandla aqinile, isivuno, amavelu amade, namavelu womthelela nge-ASTM A957 ngayinye yokulingisa kanye ne-ASTM E8 yamasampuli omshini. Ngemibhobho ye-cobalt alloy, sibika ukusatshalaliswa kwe-carbide ngemephu ye-SEM-EDS—hhayi nje ikhemistri eyinqwaba. Asihlangani nje ne-AMS 5387; siqinisekisa i-carbide morphology ngokumelene ne-AMS 2269. I-Surface finishes? I-Ra 0.4 µm ayanele uma ukuphakama kwe-peak-to-valley kudlula u-3.2 µm—ngakho sikala kokubili. Futhi yebo, sigcina izitifiketi zezinto ezibonakalayo iminyaka eyisikhombisa, hhayi emibili. Lokhu akukona ukudlula ngokweqile. Kuyindlela esivimba ngayo i-valve yokucindezela eyodwa ehlulekile ukuthi imise ulayini wokuhlanganisa izimoto zobunjiniyela eziyizigidi ezingama- $2.3 eNingizimu-mpumalanga ye-Asia.
Isinyathelo Sakho Esilandelayo Akukona “Ukuthola Ikhotheshini”—“Ukuqinisekisa Inqubo”
Ngaphambi kokuthumela imidwebo, buza owakho imboni elahlekile yokuphonsa ingcina imibuzo emithathu: Ungasibonisa idatha ye-Cpk yenyanga yokugcina yama-diameter abalulekile ezingxenyeni ezifanayo ze-cobalt? Ingabe wenza ukuhlolwa kwe-ultrasonic kuyo yonke indawo engaphezu kuka-15 kg? Ingabe isistimu yakho yokuhlanganisa igobolondo iqinisekisiwe ngezinsalela zomlotha ophansi wezinga le-aerospace? Uma izimpendulo zingacacile—noma okubi nakakhulu, “silandela umkhuba ovamile”—uhambe. Ukunemba akuchazwa izincwajana zokumaketha. Kufakazelwa esakhiweni sokusanhlamvu sendlu yephampu ye-AMS 5387 ehlukaniswe izigaba, ngokuphindaphinda kobukhulu bodonga obungu-0.008-mm emigodini engu-12, futhi ngenxa yokungabikho kokusebenza kabusha endaweni esebenzayo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha lokho kwethembeka kuzo zonke izigaba-hhayi njengesengezo, kodwa njengesistimu yokusebenza. I-prototype elandelayo oyigunyazayo ngeke imane ihlangabezane nokucaciswayo. Izosinda emijikelezweni engu-15,000 ku-220°C ngaphandle kokuqaliswa kwe-microcrack. Lokho akulona ithemba. Yilokho okwenzekayo lapho i-metallurgy, i-metrology, nokukhiqiza kukhuluma ulimi olufanayo.
