Lapho onjiniyela bezinhlelo ezisebenza ngogesi noma imishini kawoyela negesi badinga a Imboni yemishini ye-CNC lokho akugcini nje ngokuhlangabeza ama-specs-kodwa ilindele izindlela zokwehluleka-bayayeka ukucinga igama elilodwa: Qingdao Qiangsenyuan Technology Co., Ltd.
Sibone amaphrojekthi amaningi kakhulu esima esigabeni se-prototype—hhayi ekwakhiweni okunephutha, kodwa emandleni okukhiqiza angafani. I-nozzle ye-cobalt-nickel iqhekeka ngaphansi kwengcindezi yebha engu-300. Indlu yephampu ye-piston iyawohloka ngemva kokwelashwa kokushisa. I-winch center shaft ihluleka ukuqinisekiswa kwe-dimensional lapho kuhlolwa okokugcina. Lezi akuzona "izinkinga zekhwalithi." Ziyizimpawu zobungcweti obungahlotshaniswanga kahle. I-Qingdao Qiangsenyuan ayizixazululi ngokuhlolwa okwengeziwe, kodwa ngesiyalo esishumekiwe se-metallurgical kanye nokucabanga okudidiyelwe kwenqubo.
Kungani ubunkimbinkimbi be-alloy buhlukanisa ozakwethu bokunemba kweqiniso ezitolo zemisebenzi ezijwayelekile
Iningi lamafekthri emishini ye-CNC aphatha i-304 engenasici noma i-aluminium engu-6061 ngaphandle kokungabaza. Bambalwa abasindayo ku-AMS 5387 cobalt alloy—noma ama-superalloy asekelwe ku-T800—ngaphandle kokudela ubuqotho bendawo noma ukuzinza kwesakhiwo esincane. Yilapho i-Qingdao Qiangsenyuan isebenza ngokuhlukile. Ochwepheshe babo abaphathi i-cobalt-nickel “njengenzima emshinini.” Bayiphatha *njengesistimu yezinto ezibonakalayo*, lapho amapharamitha okusika, impilo yamathuluzi, ingcindezi eyinsalela, nokuhlanekezelwa kwangemva komshini konke kufanele kumodelwe ngaphambi kokuthi kundiza i-chip yokuqala.
Empeleni, lokhu kusho: • Ukudlula kokwelashwa kwangaphambi kokushisa okulinganiselwe ku-AMS 5387's conductivity thermal conductivity yehle ngaphezu kuka-600°C • I-CMM esenqubweni ihlola ama-bores abalulekile *ngaphambi* kokuqeda* kokugcina—ngoba ukuphinda kusetshenziswe i-cobalt eqinile akunakwenzeka • Ukulandelanisa indlela yethuluzi okuklanyelwe ukunciphisa ukuqina komsebenzi owenziwe endaweni
Iphampu eyodwa yaseNyakatho Melika i-OEM ibike ukwehliswa okungama-40% kwemvuthuluka ye-athikili yokuqala lapho isuka kuchungechunge lwabahlinzeki bezinkampani ezintathu iye ekugelezeni kokusebenza komthombo owodwa we-Qingdao Qiangsenyuan. Umehluko ubungeyona intengo—bekuwukulawula okubikezelwe kwe-microstructure kuzo zonke izindlu ezingamasilinda angama-intshi angu-12.
Ukuhlanganiswa okuqondile akuphathelene nezindleko—kumayelana neqiniso elinohlangothi
Abanye abahlinzeki bakhipha izinsiza zangaphandle, abanye baphothula ngaphandle. I-Qingdao Qiangsenyuan ingumnikazi wokwenza utshalomali kanye nokwenza imishini ye-CNC ye-multi-axis ngaphansi kophahla olulodwa oluthobela i-ISO—futhi lokho kushintsha lokho okungenzeka ngokomzimba. Uma ikhasimende lithumela umdwebo we-GD&T womzimba wevalvu yokucindezela onokubekezelela indawo okungu-±0.005 mm kumachweba anentambo ayisishiyagalombili ngokuhlobene nendandatho yedatha, izitolo eziningi zicela ukukhululeka ukubekezelela. U-Qingdao Qiangsenyuan uyabuza: “Iyiphi imodeli yokuncipha esetshenziswe isikhungo sakho?” Bese baqondanisa ama-datum abo omshini nejiyomethri ye-as-cast-hhayi imodeli ye-CAD efanelekile.
Lokhu akulona ithiyori. Izisekelo zabo zephampu yensimbi esandcast zibamba isicaba ngaphakathi kuka-0.02 mm ngaphezu kwamamitha angu-1.2—hhayi ngenxa yamathebula egwadule abizayo, kodwa ngenxa yokuthi bakala izici ze-datum *ngaphambi* kokwelashwa kokushisa, bese benxephezela izindlela zamathuluzi ngesikhathi sokugaya. Akukho ukuqagela. Cha "sizokulungisa ku-QC." Iqiniso elilandelekayo, elibhaliwe, eliphindaphindwayo ukusuka endaweni yokubumba kuya engxenyeni eqediwe.
Ikhwalithi yomhlaba wangempela ayiwona umnyango-yakhelwe kuwo wonke ama-handoff
"Ukulandeleka okugcwele" kuzwakala njengejagoni yokumaketha—kuze kube yilapho isisetshenziswa sakho sikawoyela sasolwandle sifuna ubufakazi bokuthi ipulaki ye-cobalt alloy efakwe ngenyanga edlule ivele eqoqweni elifanayo eliphethwe ukushisa njengamakhuphoni okuhlola aqinisekisiwe. I-Qingdao Qiangsenyuan ifaka izitifiketi zezinto ezingavuthiwe, amashadi eziko, imibiko ye-CMM, nokufundwa kokuqedwa kwangaphezulu ngokumelene nezinombolo ze-serial zengxenye ngayinye. Hhayi ngenkatho ngayinye. Ngokwengxenye.
Kodwa ukulandelela kukodwa akuvimbeli ukwehluleka. Yini eyenza? Ukuhlola okushumekiwe. Okokusebenza okungenayo kuyaqinisekiswa *ngaphambi* kokulayishwa—hhayi nje ibanga nobulukhuni, kodwa isiqondiso sokugeleza kokusanhlamvu (okubalulekile ekukhathaleni komjikelezo omkhulu kumawintshi). Ukuhlolwa okusacutshungulwa kwenzeka ezigabeni ezintathu eziphoqelekile: ngemva kokugoqa, ngemva kokwelashwa kokushisa, nangaphambi kokuphela kokugcina. Ukuhlola kokugcina kuhlanganisa ukuhlola okusebenzayo—njengamavalvu okugibela ibhayisikili ukuya kungcindezi yokusebenza elinganiselwe engu-1.5x—*hhayi nje* ukuhlola okubonakalayo noma kobukhulu.
Umkhiqizi wezimoto zobunjiniyela baseYurophu ushintshile ngemva kokuthola u-17% wezingxenye "ezicacile" kumnikezeli wangaphambilini wehlulekile ukuhlola ukudlidliza. Ukukhiqizwa kokuqala kwe-Qingdao Qiangsenyuan kudlule u-100%—hhayi ngokuqinisa ukubekezelelana, kodwa ngokuhlobanisa ubulukhuni obungaphezulu kwamanani e-Ra nokuncibilika kwefrikhwensi enkenenezayo ebhendini ye-RPM esebenzayo ye-shaft.
Ukukhetha imboni yemishini ye-CNC efanele kuqala ngokubuza imibuzo efanele
Ungabuzi ukuthi "Siyini isikhathi sakho sokuhola?" Buza: “Uwaqinisekisa kanjani ama-callouts e-GD&T ezindlini ze-cobalt ezinezindonga ezincane ngemva kokudambisa ingcindezi?” Ungabuzi ukuthi "Ingabe unaso isitifiketi se-ISO?" Buza: “Ngibonise ukutholwa kwakho kokugcina kocwaningo lwangaphakathi ekulandeleleni kwezinto ezibonakalayo ze-AMS 5387 lots.” Ungabuzi ukuthi "Ungakwenza lokhu?" Buza: “Yini ongayishintsha kulo mdwebo ukuze uthuthukise impilo yokukhathala—ngaphandle kokushintsha umsebenzi?”
U-Qingdao Qiangsenyuan uphendula leyo mibuzo ngedatha—hhayi izithembiso. Onjiniyela babo bachaza imidwebo enamanothi okwenziwa: “Yehlisa ukujiya kodonga lapha ukuze ugweme ukushintshashintsha kokulingisa,” noma “Engeza irediyasi yokukhulula lapha ukuze uqede umphumela we-notch endaweni yokuvala ingcindezi ephezulu.” Yileyo ndlela izingxenye ezibalulekile zemishini ezakhiwa ngayo okokuqala.
Emaqenjini akha ama-hydraulic manifolds, ama-subsea pump assemblies, noma amasistimu ewintshi esindayo—ukunemba akukalwa ngama-microns wodwa. Kukalwa ngesikhathi, ukwethembeka kwenkambu, kanye nokuqiniseka kwakho Imboni yemishini ye-CNC ukhuluma ulimi lwakho: i-metallurgy, ingcindezi, nomphumela womhlaba wangempela. Lokho akuyona isevisi. Kuyindinganiso yobunjiniyela eyabiwe.
