Lapho onjiniyela bayacacisa izinga okusezingeni eliphezulu utshalomali casting ifektri ozakwethu bezingxenye zensimbi ezibalulekile kumishini, abagcini nje ngokuthenga izingxenye-bavikela ukuqina kohlangothi ngaphansi kwengcindezi engu-300 MPa, ukungaguquguquki kwe-microstructural kuwo wonke amayunithi angamayunithi angama-500, kanye nokungabekezeleli i-porosity ku-cobalt alloy nozzles. Sibonile amaqembu okuthenga enqaba izingcaphuno ezintathu ezilandelanayo—hhayi ngenxa yenani, kodwa ngenxa yokuthi abahlinzeki ababili abakwazanga ukuqinisekisa amajika okwelapha ukushisa kwe-AMS 5387, futhi oyedwa ubentula ukulandeleka kwe-CMM kwama-callout e-GD&T ezindlini zamasilinda ephampu ye-piston. Yilapho ukunemba kuyeka khona ukuba yincazelo futhi kuba isiyalo senqubo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kusukela kuleso siqondiso-hhayi njengomthengisi we-casting, kodwa njengesandiso sokusebenza sethimba lonjiniyela lekhasimende. Indawo yayo ye-Qingdao ayisebenzisi imigqa yokusakazwa kwezimali ejwayelekile. Isebenzisa ukugeleza kokusebenza kwe-casting-machining okuhlanganiswe ngokuqinile lapho ingxenye ngayinye ye-cobalt-nickel ingena amasango okuhlolwa abhaliwe amahlanu: ukuqinisekiswa kwezitifiketi zempahla eluhlaza, ukuhlolwa kobukhulu bephethini ye-wax, ubuqotho begobolondo i-X-ray, imephu yobulukhuni bokwelapha ngemva kokwelashwa, kanye nokuskena kokugcina kwe-CMM ngokumelene nejometri ye-CAD egcwele. Asikho isinyathelo eseqiwa. Alikho iqoqo elikhishwayo ngaphandle kokulandeleka okugcwele kwempahla—kuze kufike kunombolo encibilikayo, i-ID yesithando somlilo, nesiginesha yomsebenzisi. Lena akuyona ithiyetha yokuthobelana. Kuyindlela abamba ngayo ukubekezelelana okungu-±0.02 mm kumarola e-T800 alloy center shaft asetshenziswa ezinhlelweni zamawintshi asogwini lapho ukungaboni ngaso linye kubangela ukwehluleka ukuthwala okuyinhlekelele phakathi kwamahora angu-47 okusebenza.
Amafekthri amaningi aphatha ama-cobalt alloys “njengamashini anzima.” I-QINGDAO QIANGSENYUAN iwathatha njengesivimbelo sedizayini okufanele yenziwe ngaso sonke isikhathi—kusuka esu lokungena ukuya emijikelezweni yokudambisa ingcindezi. Basakaze izingxenye zephampu ze-AMS 5387 ezingaphezu kuka-12,000 kusukela ngo-2021. Yonke iyunithi yabelana ngokufana kwesakhiwo sokusanhlamvu, okuqinisekiswa yizingxenye eziphambano ze-metallographic ezithathwe ezindaweni ezintathu ze-axial ngokusakazwa ngakunye. Indlela yabo eyingxube ye-sand-to-investment yezindlu zensimbi ezinkulu isusa ukushintsha okubalulekile okuvamile ekubunjweni kwesihlabathi esivamile—okubalulekile lapho kwenziwa ngomshini izindawo zokuvala zamavalvu omfutho we-hydraulic alinganiselwe kumabha angu-450. Amakhasimende awabuzi ukuthi "Ungakwenza?" Babuza ukuthi "Lithini izinga lakho lokunqaba kule geometry?" Impendulo: U-0.37% wokwakhiwa kwe-athikili yokuqala, wehlela ku-0.11% ngemva kokuzinzisa kwenqubo-okulandelelwa ngesikhathi sangempela, okwabelwana ngakho ngokusobala, akuzange kufinyelelwe ku-KPI yenkampani.
Ukuhlanganiswa okuqondile lapha kusho ukulawula—hhayi ukunethezeka. Lapho i-OEM yase-Europe idinga isisekelo sephampu yensimbi engagqwali ene-Ra ≤ 0.8 µm yokuqedwa kwendawo emizileni yokugeleza yangaphakathi, ithimba alizange likhiphe ukupholisha ngaphandle. Balungisa imvamisa yokudlidliza ngesikhathi sokushiswa kwegobolondo, bashintsha isilinganiso se-ceramic slurry binder, futhi baphinda basebenzise ukulingisa okushisayo kwawo wonke umjikelezo wokudonswa kwewaxing—bese kugunyazwa ngezikena ze-profilometer ngaphambi kokuthi kuqale ngisho nokuqala. I-CNC ayiyona into ecatshangelwayo; ivumelaniswa nokusakazwa kwedatha yokuncipha. Imishini yabo enama-axis amaningi isebenzisa inqubo yokuhlola ukuze inxephezele ukuhlanekezela okuncane, iletha ukunemba kwesimo sangempela ngaphakathi kuka-0.015 mm ezicini eziqhelelene ngamamilimitha angu-200 ekubunjweni okukodwa okungu-45-kg. Lelo zinga lokuxhumanisa likhona kuphela lapho ukusakaza, ukwelashwa ngokushisa, kanye nokubika ngomshini kumthofu owodwa wobunjiniyela—hhayi iminyango emithathu ehlukene.
Abathengi bomhlaba bakhetha lokhu izinga okusezingeni eliphezulu utshalomali casting ifektri hhayi ngezindleko eziphansi, kodwa ngenxa yengozi ephansi *ingqikithi*. Amakhasimende asezindaweni zikawoyela eNyakatho Melika athembele kumthethonqubo wokuphendula wokungalandeli okubhaliwe—isilinganiso samahora ayi-18 ukusuka ekuhlonzweni kokukhubazeka kuye ekuhlaziyweni kwembangela. Abakhiqizi bephampu baseNingizimu-mpumalanga ye-Asia basebenzisa isevisi yabo yokubuyekeza idizayini yangaphambi kwesikhathi ukuhlaba umkhosi izingxabano ze-GD&T ngaphambi kokuqala kwamathuluzi, behlisa izindleko ze-NRE kufika ku-34%. Indawo yabo ethobela i-ISO ayigcini nje ngokufinyelela amazinga—ibonisa yonke imiphumela yokuhlolwa ibe yi-ASME B16.34, ASTM A958, kanye nezidingo ze-EN 10213 ngesikhathi sangempela. Uma ubheka phambili, ukugxila kwabo kwe-R&D akukhona kumaziko amakhulu noma kumarobhothi asheshayo. Kusezinhlelweni ezixubile eziseduze-netha ezinciphisa isikhathi somshini wamabhomu e-cobalt alloy ngo-62% kuyilapho kuthuthukisa impilo yokukhathala—kugunyazwe ngokuhlolwa kwe-pressure pulsation engu-10,000. Ukulingisa okunembayo akukhona ukuthela insimbi encibilikisiwe. Kumayelana nokwazi kahle ukuthi yonke i-athomu izozinza kuphi—futhi ikufakazele.
