Lapho onjiniyela becacisa a casting Foundry factory ezingxenyeni zensimbi ezibaluleke kakhulu kumishini, azithengi nje izingxenye—zivikela ukuqina kohlangothi ngaphansi kwengcindezi yamabha angu-300, ubuqotho be-microstructural ngemva kokuhamba ngebhayisikili elishisayo, kanye nokuqedwa kwendawo okumelana nokuguguleka kwe-slurry. Sibone amaphrojekthi amaningi ebambezelekile ngenxa yokuthi umphakeli osakaza akakwazanga ukubamba ±0.05 mm endlini yephampu ye-cobalt-alloy—noma okubi nakakhulu, ulethe impahla ye-AMS 5387 enosayizi wokusanhlamvu ongekho. Kungakho ukwethembeka kuqala isikhathi eside ngaphambi kokuthulula insimbi encibilikisiwe: kuqala ngokulandeleka kwe-alloy, isiyalo senqubo, nokuqondanisa kobunjiniyela esigabeni sokubuyekeza umdwebo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzisa indawo eqinisekisiwe ethobela i-ISO e-Qingdao lapho ukulingisa nokunemba kwemishini kungezona izinyathelo ezilandelanayo—kuyimisebenzi evumelanisiwe. Ukusakaza kwesihlabathi nokusakazwa kwe-investimenti okuphakelayo ngokuqondile kumaseli e-CNC e-multi-axis. Awekho ama-handoffs. Akukho ukudluliselwa kwenqwaba phakathi kwezinsiza. Lapho ikhasimende lithumela umdwebo we-GD&T-rich wezindlu zesilinda sephampu ye-piston, ithimba lethu liqinisekisa izilinganiso zokuqina kwezindonga ngokumelene nedatha yokulingisa yokuqinisa *ngaphambi* kokugunyazwa kwephethini—futhi libeka izingozi zokubeka amafulegi ezingase zibangele i-microporosity ezindaweni ezinengcindezi ephezulu. Sibambe u-12% wemiklamo ethunyelwe enama-undercuts angenakunyakaziswa angaphoqelela ukwakhiwa kabusha kwe-EDM ebizayo noma ukulahlwa. Akuyona i-QA leyo. Kuwukubona kwangaphambili kwe-metallurgical.
Abahlinzeki abaningi baphatha ama-cobalt-nickel alloys “njengamashini anzima”—bese bema lapho. Siwaphatha njengamasistimu anenkumbulo eshisayo echaziwe. Imibhobho esekelwe ku-T800 nezingxenye zephampu ze-AMS 5387 zidinga amawindi anembayo okwelapha ukushisa: ukufakwa kwesisombululo ku-1180°C ±5°C, okulandelwa ukupholisa okulawulwayo ukuze kugwenywe ukuduma kwesigaba se-sigma. Izingodo zethu zesithando somlilo ziboshwe ezindaweni zokushisa ngazinye; ingxenye ngayinye iphethe iphasiphothi ebonakalayo ebonisa ukuhlaziywa kokuncibilika, imiphumela yokuhlolwa okuqinile, nosayizi wokusanhlamvu nge-ASTM E112 ngayinye. Iklayenti elilodwa lasendaweni kawoyela eNyakatho Melika lashintshela kithi ngemva kwamaqoqo amathathu alandelanayo avela komunye umthengisi ehlulekile ukuhlolwa kokuqina—ngoba umphakeli walo wasebenzisa imijikelezo yesithando somlilo esijwayelekile esikhundleni sezikhathi zokucwiliswa kwengxube eqondile. Asiwasebenzisi amashejuli—sisebenzisa amaresiphi e-metallurgical.
- Ukubunjwa kwensimbi emizimbeni ye-hydraulic valve: EN-GJS-400-15 insimbi eyi-ductile, idutshulwe ukumelana nokukhathala, nobulukhuni buqinisekiswe ngezikhathi ezintathu zokujula
- Insimbi engagqwali castings ngezisekelo zephampu engaphansi kolwandle: I-ASTM A743 CF8M, ihlolwe nge-ultrasonically yafika ku-Level B, yaphasiswa nge-ASTM A967 ngayinye
- Izingxenye ze-cobalt alloy: Imibhobho ye-AMS 5387 enobunzima obungalinganisi bendawo engu-Ra ≤1.6 µm—akukho ukugaya kwesibili okudingekayo ukuze kuvalwe indawo
- Ama-hybrids enziwe ngomshini we-CNC: Izindlu zensimbi ezifakwe endaweni eziqedwe nge-5-axis contouring ukuze zibambe ukubekezelela indawo okungu-0.02 mm kumaflange akhuphukayo
Ukungaguquguquki kokulethwa akuphathelene namabhafa we-inventory—kumayelana nokulawulwa kokuhamba komsebenzi. Sisebenzisa ukuhlelwa kokukhiqiza okuqinile ngokulandela isikhathi se-takt ngomndeni we-oda ngalinye. Ukugijima kwe-Prototype kuthola ukuhlela okuzinikele kweseli; ama-oda evolumu emaphakathi akhiya ezindaweni zokulingisa zamasonto onke ngezinto ezingavuthiwe ezabiwe kusengaphambili ezivela ezigayweni eziqinisekisiwe. Lapho imoto yobunjiniyela base-Europe i-OEM idinga ama-roller amaphakathi eshaft angama-47 amawintshi agibele—ilinye linesisindo esingu-82 kg, elinamadayamitha angu-17 abalulekile kanye nezindawo zokuguga eziqinile—sahambisa izingxenye ze-athikili yokuqala ngezinsuku ezingu-22. Hhayi ngoba sashesha, kodwa ngenxa yokuthi umjikelezo wethu wokulungiselela isikhunta sesihlabathi ulinganiswe amahora angama-38, futhi uhlelo lwethu lokuhlola lwe-CMM lulayishwe kusengaphambili imininingwane eshiwo ngamakhasimende. Awekho amalophu okusebenza kabusha. Akukho ukubambezeleka kokulinganisa ngomzuzu wokugcina.
Amakhasimende omhlaba—kusuka kubahlanganisi besistimu ye-hydraulic e-Milwaukee ukuya kubakhiqizi base-Singapore—angasikhethi ngentengo ephansi. Basikhetha lapho ukwehluleka kungeyona inketho. Uma ipulaki ye-cobalt alloy ivala u-250°C isitimu ku-turbine ye-geothermal, noma lapho ukusakaza kwensimbi engagqwali kusinda iminyaka engu-15 ekucwilisweni emanzini anosawoti asolwandle, ukwethembeka akulona iqiniso. Yakhiwe ngendlela eqinile, iqinisekiswa kuyo yonke indawo yokushisa, futhi isayinwe onjiniyela abema eduze kwesithando somlilo ngesikhathi sokuthela. Ngokuzayo uma ucacisa a casting Foundry factory, buza ukuthi bayisingatha kanjani i-AMS 5387 yokulawula ukukhula kokusanhlamvu—hhayi nje ukuthi “iyakwazi ukuyiphonsa.” Buza izitifiketi zabo zezinto ezintathu zokugcina. Cela ukubona umbiko wabo we-CMM mayelana nezindlu zakamuva zevalvu yokucindezela. Bese uqhathanisa lokho okutholayo: ukuthobela iphepha—noma ukusebenza okuqinisekisiwe.
