Uma i-valve yakho ye-hydraulic ihluleka ku-3,000 psi-noma i-cobalt-alloy pump housing crack ngaphansi kokuhamba ngebhayisikili eshisayo-awudingi omunye umhlinzeki "ophatha ama-alloys." Udinga i i-alloy precision machining factory lokho sekuxazulule lokho kwehluleka esitezi sesitolo.
Sizibonele mathupha: i-OEM yaseNyakatho Melika ilibazise ukuthunyelwa izikhathi ezintathu ngenxa yokuthi umthengisi wayo wangaphambilini wayifunda kabi izingcingo ze-GD&T ku-AMS 5387 cylinder housing. Ingxenye iphumelele ukuhlolwa kwe-dimensional-kodwa yehluleka ukuhlolwa kwengcindezi. Kungani? Ngoba ubuqotho obungaphezulu kanye nokuvumelana kwe-microstructural akuzange kuqinisekiswe eceleni kwejometri. Lokho akulona iphutha lomshini. Kuyigebe lezinhlelo.
Ukunemba kwangempela kuqala lapho ukulingisa kuphelela khona—futhi lapho kuqala khona ukwenziwa kwemishini
Abahlinzeki abaningi baphatha ukusakaza kanye ne-CNC njengezisele ezihlukene. Iqembu elilodwa lithela insimbi. Omunye umshini. Kodwa izingxenye ze-alloy ezibekezelela kakhulu—ikakhulukazi kuwoyela negesi, ama-hydraulics asindayo, noma imihlangano yephampu ebaluleke kakhulu—idinga ukuqhubeka kuzo zombili izigaba. Ukuzinza kwe-Dimensional akukhona nje ukubekezelelana okuqinile embikweni we-CMM. Kumayelana nokuthi ingcindezi eyinsalela evela ekuqinisweni ihlangana kanjani namandla okusika ngesikhathi sokugaya i-multi-axis. Kumayelana nokuthi ukwelashwa kokushisa ngemuva komshini kuthinta kanjani ukuhlangana komngcele wokusanhlamvu ezintweni ezisekelwe ku-T800 cobalt.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukusakaza akuwona umsebenzi olungiselelwe wokwenza imishini—kuyisinyathelo sokuqala esinembayo. Indawo yabo ethobela i-ISO isebenzisa ukufakwa kwezimali okuhambisanayo kanye nemigqa yokusakazwa kwesihlabathi elinganiselwe ngokukhethekile i-cobalt-nickel, insimbi engagqwali, kanye namamaki ensimbi aqine kakhulu. Ukulandelelwa kwempahla eluhlaza kuqala esitifiketini sokugaya—hhayi endaweni yokwamukela izivakashi. Yonke inqwaba ye-AMS 5387 ithola ukuqinisekiswa kwe-spectrographic ngaphambi kokuthululwa. Yonke i-T800 alloy lot iphathwa ngokushisisa nge-AMS 2750 ngayinye, namalogi esithandweni aboshwe ngokuqondile ezingxenyeni zezinombolo ze-serial.
Lokhu kuhlanganiswa okuqondile kuqeda izindleko ezinkulu ezifihliwe ekukhiqizeni kwe-alloy ephezulu: ukusebenza kabusha okubangelwa ukuqagela kwe-metallurgical okungafani. Lapho ithimba elifanayo lilawula kokubili umgodi wokubumba kanye nendlela yamathuluzi, lazi kahle ukuthi lizosusa kuphi izindawo zokuhlukanisa—nokuthi lisishiye kuphi isitoko ukuze linciphise ukucindezeleka kokugcina.
Awuzithengi izingxenye. Uthenga ukuthembeka kokusebenza
Bheka izindlu zabo zesilinda sephampu ye-piston. Akuzona ezijwayelekile “izingxenye zomshini ze-CNC”—kodwa amayunithi ano-±0.005 mm athwala ukugxila, izindawo eziqinile ezihlangana ne-ASTM A957 Class 1, nezindlela zokugeleza zangaphakathi ezipholishelwe ku-Ra 0.4 µm. Noma imibhobho yabo ye-cobalt alloy: eyenziwe kusukela ku-AMS 5387, bese iqeda ngokususa i-electrochemical ukuze kuqedwe ama-micro-notches aqala ukuqhekeka kokukhathala kumafrikhwensi wokudlidliza angu-120 Hz.
Lokhu akuwona ama-specs akhishwe kukhathalogi. Imiphumela egunyazwe kuwo wonke amahora okukhiqiza angu-17,000+ emishinini yomhlaba wangempela—kuhlanganise namaphampu asolwandle asebenza ngokuqhubekayo ku-120°C namarola e-winch center yewintshi yemoto yobunjiniyela angaphansi kwemithwalo ye-torsional yemijikelezo engu-400,000.
Abanye bangase baphikise ngokuthi ukusakaza + ukwenza imishini kwengeza ubunkimbinkimbi nesikhathi sokuhola. Kepha ekusebenzeni, ukuhamba kwabo okuthambile kucindezela isikhathi somjikelezo *ngoba* akukho ukubambezeleka kwe-handoff phakathi kwe-Foundry nesitolo somshini. Akukho ukulinda ukuthi ukulingisa kuphole, kuthunyelwe, kuhlolwe, futhi kufakwe umugqa kabusha. Awekho amalophu okuklama kabusha lapho ijiyomethri ye-as-cast ingafani nokuqagela kwesoftware ye-CAM. Iqembu elilodwa liphethe inqubo egcwele—kusuka ekudwebeni kokuqinisekisa kuya ekuhlolweni kokugcina kokusebenza.
Ikhwalithi ayihloliwe. Iklanywe ngesinyathelo ngesinyathelo esibhaliwe
Ngena kulebhu yabo yokuhlola futhi uzobona okungaphezu kwama-CMM. Uzobona iziqhathanisi ze-optical ziqinisekisa ama-angles e-flank wentambo kumapulagi e-cobalt alloy. Uzobona iziteshi ezifaka udayi ezisetshenziswa kuwo wonke umzimba we-valve yokucindezela—hhayi nje amasampula. Uzobona imibiko yokuhlolwa kokubalulekile okubhekiselwe kuyo ngokumelene nezinombolo zokushisa, nedatha eqinile efakwe kusizindalwazi esivikelekile esifinyeleleka kumakhasimende uma ecelwa.
Akukho "isampula ye-AQL." Awekho amabhokisi okuhlola “edlula/ehlulekayo ukuhlola kokugcina”. Bonke ubungako obubalulekile bulinganiswa kabili—kanye ngemva kokugoqa, kanye ngemva kokuqeda—ngokulandela amathrendi okuchezuka ngenkatho ngayinye. Yonke indawo engaphezulu iqinisekiswa ngokumelene nezidingo zokusebenza ezicaciswe yikhasimende: hhayi nje amanani e-Ra, kodwa imikhawulo ye-waviness, isibalo esiphezulu, namajika esilinganiso sokuthwala lapho kudingeka khona.
Lesi siyalo siletha okuthile okungajwayelekile ekukhiqizweni kwengxubevange yomhlaba: ukulethwa okungaguquguquki kwama-oda evolumu ephakathi (50–500 pcs/lot) ngaphandle kokudela isivuno sokuqala. Ama-prototypes athunyelwa ngezinsuku zokusebenza eziyi-12. Ama-oda okukhiqiza afinyelela ku->98% ukulethwa ngesikhathi—ngisho nezinqubo eziyingxubevange eziyinkimbinkimbi ezifana ne-investment-cast + 5-axis-machined + vacuum-brazed assemblies.
Yini eyenza i-alloy precision machining factory yehluke ngempela?
Izinto ezintathu ezibahlukanisayo nezitolo zemisebenzi ejwayelekile:
- Ukushelela kwezinto: Hhayi nje "ukwenza ama-cobalt alloys," kodwa ukwazi ukuthi izinga le-T800 lokuqinisa umsebenzi lishintsha kanjani izinga lokuphakelayo ku-220 m / min isivinini se-spindle-kanye nokulungisa ingcindezi yokupholisa ngokufanele.
- Ukuziphendulela okusebenzayo: Ababuzi ukuthi "Yikuphi ukubekezelelana okudingayo?" Babuza "Iyiphi imodi yokwehluleka ozama ukuyivimba?" Bese uqondanisa izilawuli zenqubo kuleyo mpendulo.
- Ubunjiniyela obala: Izibuyekezo zokudweba zihlanganisa amanothi emakhaphu afana nokuthi “Le radius izobamba i-slag ekusetshenzisweni kwe-investimenti—incoma ukuthi ikhuphuke ibe ngu-R0.8 ukuze kuqinisekiswe ukugcwaliswa okuhlanzekile” noma “uhlaka lwe-GD&T lapha lungqubuzana nobuqotho obungafinyeleleka—phakamisa ukubekezelelana kwephrofayela okuphumuzayo ngo-0.01 mm nokwengeza i-callout yokwakheka kwendawo.”
Uma iphrojekthi yakho elandelayo ihlanganisa amavalvu okucindezela, isisekelo sepompo, noma izingxenye ze-cobalt-nickel ezingajwayelekile ezidinga ukusebenza kwangempela kokubekezelela okuphezulu—ungaqali ngama-RFQ. Qala ngesibuyekezo sokwenziwa. Ngoba ingxenye eqine kakhulu akuyona leyo enezici eziqinile. Yilowo owakhiwa kahle okokuqala-njalo.
