Uma amasistimu we-hydraulic endiza ehluleka phakathi nokundiza, imbangela eyinhloko akuyona isofthiwe—kuwukuchezuka kwezinga le-micron endaweni yevalvu yokucindezela noma i-microcrack eshisayo kubhobho ye-cobalt-alloy. Kungakho ifekthri yemishini yokunemba emkhathini ingewona umugqa wethegi wokumaketha. Kungumkhawulo wokusebenza ongaxoxiswana ngawo. Sike sabona ama-OEM amathathu enqaba wonke amaqoqo okukhiqiza—hhayi ngoba izingxenye zephukile, kodwa ngenxa yokuthi imibiko ye-CMM ibonise ukuphuma kwe-axial okungu-0.008 mm kundlu yesilinda sephampu ye-piston ehloselwe ukulayisha umjikelezo wamabha angu-350. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., lelo gebe phakathi kokuthi "ngaphakathi kokucaciswa" kanye "nokulungela ukundiza" lichaza umsebenzi wethu wansuku zonke.
Lapho Ukubekezelelana Kuhlangana Nokuzinza Okushisayo: I-Machining Superalloys Ngalé kwe-AMS 5387
Izitolo eziningi zizibiza ngokuthi “precision” zize zibhekane ne-T800 cobalt-based alloy. Ukuqina kwayo kuyakhuphuka ngemva kokwelashwa kokushisa. I-thermal conductivity yayo yehla ngaphansi kuka-12 W/m·K. Amathuluzi ajwayelekile e-carbide axoxa; inkungu epholile iyahwamuka ngaphambi kokuba ifike endaweni esikiwe. Asikukhiphi lokhu. Indawo yethu ethobela i-ISO e-Qingdao isebenzisa amaseli e-CNC ane-axis eminingi anokupholisa nge-spindle ku-100 bar pressure, amathuluzi ahlanganiswe nge-ceramic, kanye nokuqapha ngesikhathi sangempela umthwalo wokuphotha. Lapho ikhasimende lisithumelela izingxenye zephampu ze-AMS 5387 ezidinga ukulawula okungu-±0.005 mm GD&T ezicini zedatha eziphambanayo ezingu-12, senze imephu yokukhukhuleka okushisayo phakathi nomjikelezo womshini wamahora angu-16—sabe sesilungisa ukulandelana kwe-clamping ye-fixture futhi sethula ukupholisa komoya okuphakathi nendawo phakathi kwamaphasi amahlonyana namaqeda. Umphumela? Isivuno sokuqala esingu-98.7% endaweni engama-42-piece. Akukho ukusebenza kabusha. Azikho izimvume.
Kungani i-Casting + Machining Integration Ishaya amaSilo “Angcono Kakhulu Ekilasini”
Ezinye izimangalo zefekthri yokunemba kwefekthri ye-aerospace zigxila kuphela ku-CNC. Lokho kudala izindawo eziyimpumputhe. Ukufakwa kwensimbi kungase kuhlangabezane nokucaciswa kobukhulu—kodwa uma ukwakheka kwayo kwe-dendritic kuqukethe i-microporosity eduze nejenali ephethe, alikho inani le-post-machining elingabuyisela impilo yokukhathala. Siphethe imigqa yokufaka utshalomali kanye ne-sand casting. Ngaphambi kokuthulula, siqinisekisa ukulingiswa kokuqinisa ngokumelene nama-X-ray CT scans we-prototype castings. Ngemuva kokwelashwa okushisayo, iqoqo ngalinye lihlolwa nge-ultrasonic nge-ASTM E114 ngayinye, hhayi nje amasampula. Khona-ke umshini uqala-hhayi njengesigaba esihlukile, kodwa njengokuqhubeka kokulawula i-metallurgical. Kumarola e-winch center shaft asetshenziswa ezimotweni zobunjiniyela bezinga lezimayini, sisebenzisa i-OD yokugcina kanye nokhiye *ngaphambi* kokwelashwa kokushisa okwehlisa ingcindezi. Kungani? Ngoba ukusabalalisa kabusha kwengcindezi eyinsalela ngemva kokuphathwa kokushisa kuzohlanekezela ukugxila okubalulekile okungu-0.012 mm phakathi kwe-roller OD kanye ne-spline yangaphakathi. Ukuhlanganiswa okuqondile akuphathelene nokunethezeka. Kumayelana nokubopha ukusakazwa kwephutha ngaphambi kokuthi kuqale.
Ukulandelelwa Okungami Esitifiketini Sokugaya
Isitifiketi sokugaya sifakazela ikhemistri. Akufakazeli ukuthi umzimba wakho we-valve usinde emijikelezweni engu-12,000 ku-220°C ngaphandle kwe-oxidation yomngcele wokusanhlamvu. Isistimu yethu yokulandeleka ixhumanisa ingxenye ngayinye nenombolo yokushisa yezinto ezingavuthiwe, i-ID yenqwaba yesithando somlilo, inguqulo yohlelo lwe-CNC, i-ID yebheji yomsebenzisi, isitembu sesikhathi sokulinganiswa kwe-CMM, kanye nesilinganiso sokuqina kwendawo (Ra ≤ 0.4 µm, iqinisekiswe nge-stylus profilometer). Lapho umphakeli we-European Tier-1 edinga ukusekelwa okugcwele kokuhlolwa kwe-EASA Ingxenye ye-21G, sithumele imibhalo yedijithali ebonisa ukuthi i-T800 billet efanayo yondla kanjani kokubili ipulagi ye-cobalt alloy kanye nombhobho we-AMS 5387—okufakazela i-microstructure engaguquki kuzo zonke izingxenye ezisebenzayo ezihlukene. Awekho amaspredishithi. Awekho izingodo zephepha. Lonke irekhodi lifakwe isitembu sesikhathi, libethelwe, futhi lifinyeleleka ngengosi evikelekile phakathi kwamasekhondi angama-90.
Ukulethwa Kwangempela, Hhayi Izikhathi Zokuhola Ezethiyori
"Isikhathi sokuhola esijwayelekile: amaviki ayi-12." Leyo nkulumo ibiza onjiniyela ubuthongo. Sizibophezela emigqeni yesikhathi kuphela ngemva kokuqinisekisa ukwenziwa kwezinto—hhayi nje ukufunda imidwebo, kodwa silingisa ukukhishwa kwe-chip emigodini ejulile eyimpumputhe, ukuhlola ama-engeli okufinyelela amathuluzi ukuze uthole ama-undercuts, kanye nokuqinisekisa ukuthi kungenzeka ukuqeda phezulu endaweni egobile ye-cobalt. Ngama-oda esibonelo, sithumela amasampula okuhlola asebenzayo phakathi nezinsuku zokusebenza eziyi-18—ngisho nezingxenye ezidinga ukwelashwa kwe-vacuum nokudlula. Ukugijima kwevolumu emaphakathi (ama-pcs angu-50–500) ngomkhumbi emavikini angu-6–8, kukhiyiwe ekusayinweni kwenkontileka. Kanjani? Izinqubo zokugeleza komsebenzi ezinciphile zisho ukuthi alikho iqoqo elilinda ukuhlolwa. Ukuhlolwa kwe-CMM kwenzeka *ngesikhathi* somshini—zonke izingxenye ze-10 ezicini eziyingozi kakhulu. I-QA yokugcina ayilona isango. Yindawo yokuhlola evumelanisiwe ehambisana nesigqi sokukhiqiza. Amakhasimende aseNyakatho Melika, eYurophu, naseNingizimu-mpumalanga ye-Asia aqinisekisa: uma i-BOM yabo idinga i-valve yokucindezela noma isisekelo sepompo esakhelwe ku-ASME B16.34 ne-ISO 2768-mK, bayayithola—ngedethi ethenjisiwe, nemibhalo egcwele, akukho okuhlukile.
I-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njengemboni yomshini wokunemba emkhathini lapho ukunemba kobukhulu kusebenzela ubuqotho besakhiwo—futhi kokubili kunikeza ukwethembeka okubalulekile komgomo. Sifaka ama-alloys e-cobalt-nickel hhayi ngoba angavamile, kodwa ngoba ayadingeka. Asihlanganisi ukusakaza kanye ne-CNC ngokusebenza kahle kuphela, kodwa ukuqeda amaphuzu okuhluleka kokusebenzelana. Futhi asilethi ukuze sihlangabezane namashejuli, kodwa ukuze sigcine indiza endizayo, amaphampu esebenza, namasistimu azinzile—kuze kufike kumakron wokugcina.
