Lapho onjiniyela be-aerospace bedinga izingxenye zokusatshalaliswa kwe-investimenti ezibamba ukubekezelelana okungu-±0.05 mm ngaphansi kwemithwalo ye-hydraulic engu-300 MPa, azixazululi izisekelo zenjongo evamile. Bafuna i imboni ye-aero metals investment casting enokulawulwa kwe-metallurgical okubhaliwe, i-zero-batch drift ku-AMS 5387 cobalt alloy, nezici zomshini we-CNC eziqondaniswe nama-callout we-GD&T—hhayi nje imidwebo. Kulapho ukunemba kuyeka khona ukuba yincazelo futhi kuba inqubo ephindaphindwayo.
Sibone amaphrojekthi amaningi efadalala lapho ukulingwa kudlula ukuhlolwa kobukhulu kodwa ehluleka ukuhamba ngebhayisikili elishisayo ku--55°C kuya ku-+120°C ngenxa yokuthi ukwakheka okusanhlamvu akuzange kuqinisekiswe ukwelashwa kwangaphambili kokushisa. Noma lapho indlu yephampu iqhekeka ngemva kwamahora angu-420 omsebenzi oqhubekayo—hhayi ngenxa yokushiyeka komklamo, kodwa ngenxa ye-micro-porosity eduze nendawo yokucindezela eshelelekile ekuhlolweni okubonakalayo okudlule. Lawa akuwona amacala. Bangumehluko phakathi "komkhumbi" kanye "nokufaneleka kwendiza." Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., konke ukutshala imali kwe-cobalt-nickel kuqala ngamabhaluthi e-T800 alloy aqinisekisiwe, alandeleka enombolweni yokushisa, ngemibiko ye-spectrographic ehlolisiswe ngokumelene ne-ASTM E1096 ngaphambi kokuncibilika.
Indawo yabo ethobela i-ISO e-Qingdao ayikusebenzisi ukutshalwa kwezimali njengomugqa ozimele—ihlanganisa ngokuqinile nomshini wama-eksisi amahlanu, ukuhlanganisa izixazululo, nokuhlola okungabhubhisi. Isibonelo: umlomo wombhobho we-AMS 5387 awuphonswa, bese umshini, bese uyahlolwa. Isakazwa ngemvume yomshini engu-0.3 mm ezindaweni ezibucayi zokuvala; i-post-heat-treat in vacuum furnature iyalinganiswa nsuku zonke; enziwe ngomshini kusetshenziswa ukusethwa kwe-Renishaw-probed okunxephezela ngokuzenzakalela ukukhula okushisayo; futhi ihlolwe ngama-Zeiss CMMs asebenzisa izinqubo ezihambisana ne-ASME B89.4.10—zingalinganisi nje usayizi, kodwa iphutha lefomu, ubuqotho obungaphezulu, kanye nama-gradients asendaweni. Lokhu kuhlanganiswa okuqondile kususa ukukhishwa lapho izitaki zokubekezelelana zinqwabelana. Izindlu zesilinda sephampu ye-piston zifika ku-QA yokugcina enomlando ophelele we-dimensional—hhayi nje isitembu sokudlula/sokwehluleka.
Abanye bangase baphikise ngokuthi ukwenza isihlabathi kunikeza ukusebenza kahle kwezindleko kubakaki abakhulu besakhiwo. Kodwa kumanifolds omkhathi anezindonga ezincane, onesilinganiso esiphezulu—ikakhulukazi lawo adinga amashaneli okupholisa angaphakathi noma izindlela zoketshezi ezihlelekile—ukutshalwa kwezimali kuhlala kungenakuqhathaniswa. I-QIANGSENYUAN ifakazela lokhu ngokukhiqiza njalo ukulingwa kwensimbi engagqwali okunokuqina kodonga okungu-1.2 mm, irediya yangaphakathi engu-0.8 mm, futhi ingaphezulu iqedwa ngaphansi kuka-Ra 1.6 µm—njengoba ilethwe, hhayi ngemva kokupholishwa. Inqubo yabo yegobolondo le-ceramic isebenzisa ama-slurries asekelwe ku-zircon kanye ne-silica stucco ehlanganisiwe, okuvumela imijikelezo yokutubeka egcina imininingwane emihle ngaphandle kokuqhekeka okuncane. Futhi ngokungafani nezitolo ezakha amagobolondo angaphandle, igumbi lazo legobolondo lonke lisebenza ngaphansi komswakama oqinile nezilawuli zokushisa (±2°C, 45–55% RH), ngoba ngisho nokushintshashintsha komswakama okuncane kushintsha ukunwebeka kwegobolondo—futhi kushintsha isivinini sokugeleza kwensimbi ngesikhathi sokuthela.
Okubenza bahluke akukhona nje ikhono—indlela abalisebenzisa ngayo. Lapho i-OEM yama-hydraulics yaseYurophu idinga imizimba yama-valve yangokwezifiso engama-27 ku-T800 cobalt alloy, ayizange ivele icaphune ngokusekelwe kuvolumu yemodeli ye-3D. Onjiniyela babuyekeze izichasiselo ze-GD&T, ezimakwe izingozi ezingaba khona ze-core-shift esicini sedatha esingu-0.15 mm, baphakamise ukulungisa okusalungiswa okuncane ukuze kugwenywe ukugaya kwesibili, futhi banikeza imibiko yokuhlolwa kwezinto ezibonakalayo ebonisa amandla aqinile ≥1,380 MPa ku-650°C—kuqinisekisiwe nge-AMS ngayinye engu-2269. Lolo hlobo lokuhlanganyela kokubhala ngo-40%. Uhlelo lwabo lokuhlela oluthambile lulandelela i-oda ngalinye ngokuqhathanisa nesikhathi sangempela somjikelezo—hhayi amahora okusebenza alinganiselwe—ngakho-ke ivolumu ephakathi igijima (ama-pcs angu-50–300) zingakapheli izinsuku zokusebenza eziyi-12, ngokungaguquki. Azikho izigatshana "kuncike ekutholakaleni kwezinto ezibonakalayo". Akumangazi inkokhiso ye-NRE yokugunyaza i-athikili yokuqala.
Uma ucwaninga ngokunemba izingxenye ze-aerospace lapho ukwehluleka kusho ukwehla kwesistimu—noma okubi nakakhulu—udinga okungaphezu kwamandla okusakaza. Udinga isiyalo se-metallurgical, ukuqina kokuhlola okufana nezidingo zakho zokusebenza, nokuqondanisa kobunjiniyela kusukela ekubuyekezweni komdwebo ngokusebenzisa amaphakheji okugcina. An imboni ye-aero metals investment casting njenge-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iletha lokho—hhayi njengolimi lokumaketha, kodwa njengobufakazi benqubo obubhaliwe, izitifiketi eziqondene nenqwaba, nezingxenye ezisebenza ngokufanayo kuzo zonke izindawo zokukhiqiza. Isinyathelo esilandelayo asiqhathanisi izingcaphuno. Yabelana ngephakheji yakho ye-GD&T futhi ibuza: "Ungalilindela kuphi iphuzu lokuqala lokuba sengozini-futhi ulinciphisa kanjani?" Leyo ngxoxo ihlukanisa abahlinzeki kozakwethu.
