Lapho onjiniyela bedinga amandla efekthri yokutshala imali encane ezingxenyeni ezingaphansi kuka-50 mm ezinokubekezelela okungu-±0.02 mm nokuqedwa kwengaphezulu ngaphansi kwe-Ra 1.6 µm, abahlinzeki abaningi bashayisa udonga. Sikubone ngokuphindaphindiwe: ama-prototypes abambezeleka ngamaviki ayisithupha, ukukhishwa kwenqatshiwe ngenxa ye-micro-porosity ezindleleni zokugeleza ezibucayi, noma imibhobho ye-cobalt alloy ehluleka ukuhlolwa kwengcindezi ngemva kokwelashwa kokushisa. Lokho akuyona inkinga yezinto ezibonakalayo-inkinga yokuqondanisa inqubo.
I-Micro Investment Casting Idinga Okungaphezulu Kwezikhunta Ezincane
Ukutshala izimali ezincane kwangempela akukhona nje ukutshala izimali "okuncane". Kudinga ukulawula okuqinile phezu kokuncipha kwephethini ye-wax, ukukwazi ukungena kwegobolondo le-ceramic, ukushisa okuphezulu kwensimbi, nezinga lokuqinisa—ikakhulukazi uma kusakazwa izingxenye ezinodonga oluncane (0.8–2.5 mm) kusuka ku-AMS 5387 cobalt alloy noma ama-superalloy asekelwe ku-T800. Abasunguli abajwayelekile bavamise ukweqa imodeli yangaphambi kokukhiqiza eshisayo noma basebenzise amaresiphi egobolondo ajwayelekile. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., wonke umsebenzi wokusakaza omncane uqala ngesifaniso esiqinisekisiwe sokuqinisa—hhayi njengebhokisi lokuhlola, kodwa ukubikezela ukuthi ukucindezeleka kwensalela kugxila kuphi kupulaki yepompo engu-12-mm-diameter enamashaneli okupholisa angaphakathi.
Sake sagijima amagobolondo amathathu esihlalo sevalvu ye-hydraulic ngaphambi kokukhiya i-slurry viscosity, isikhathi sokuhlala se-dip, kanye nephrofayili yerempu yokudonsa. Umehluko? Ukuncishiswa kwe-microporosity ngo-40% esangweni—kuqinisekiswe nge-X-ray CT scan, hhayi nje ukungena kodayi. Ngaleyo ndlela ufinyelela ubuqotho obusebenzayo ezingxenyeni ezisebenza kubha engu-350 no-180°C.
Kungani Ukuhlanganiswa Okuqondile Kwehlula Ukusakaza Okungaphandle + Nomshini
Abanye abakhiqizi baphonsa okungenalutho, bese bekuthumela esitolo se-CNC. Kodwa izici ezincane ezifana nemigodi engu-0.3-mm ye-radial groove kusilinda sephampu ye-piston zidinga umshini *ngaphambi* kokwelashwa kokushisa kokugcina—ngale kwalokho, ukuhlanekezela kuchitha ukuthobela kwe-GD&T. Abanye baqala ngomshini, bese bejikijela izinto ezifakiwe—okwethula izikhala ezihlanganisa ubuso.
I-QINGDAO QIANGSENYUAN iphatha zombili endaweni eyodwa ethobela i-ISO. Isibonelo: i-cobalt-nickel alloy winch center shaft roller iqala njengesimo sokutshala imali eduze nenethi, idlule ekuxazululeni isixazululo, ivuleke ngokunemba ku-5-eksisi i-DMG Mori ene-in-process laser probing, bese ithola ukufakwa kwe-hard-chrome enogqinsi olulawulwayo (25–35 µm cross-severified by µm) Awekho ama-handoffs. Akukho ukungafani kwenqwaba. Akukho ukulandeleka okulahlekile.
- Izikhungo zemishini ye-CNC zilinganiswa nsuku zonke kumazinga we-ISO 230-2
- Izibungu zamagobolondo zomiswa emakamelweni alawulwa umswakama (RH <35%) ngaphambi kokudubula
- Wonke ama-cobalt alloys atholwe ngemibiko egcwele yokuhlolwa komshini (MTRs), okuhlanganisa usayizi wokusanhlamvu nokuhlaziywa kokusabalalisa kwe-carbide
- Yonke ingxenye efakwe kumephu ngedatha ye-CMM eboshelwe enombolweni yayo yokushisa yezinto ezingavuthiwe
Imikhawulo Yomhlaba Wangempela—Nendlela Yokusebenza Ngaphakathi Kuyo
Ukutshala izimali ezincane akuwona umlingo. Ukujiya kodonga ngaphansi kuka-0.6 mm kubeka engcupheni ukugcwaliswa kwesikhunta okungaphelele. Izici ezingaphansi kuka-0.2 mm azivamile ukusinda ekukhishweni kwegobolondo ngaphandle kokuguguleka. Futhi yebo—i-AMS 5387 incipha ngo-1.92% ngokwesilinganiso, kodwa ukuncipha kwendawo kungahluka ±0.15% kuye ngesisindo esiseduze. Amanye amaklayenti acabanga ukuthi elithi “micro” lisho ukuthi “akukho okusalungiswa.” Akulungile. Ngisho nokusalungiswa okungu-0.5° kusindisa ukuphila kwamathuluzi futhi kuvimbele ukuqhekeka kwegobolondo ngesikhathi sokuxosha.
Kungakho isibuyekezo sobunjiniyela bethu amafulegi aklama amafulegi kusenesikhathi: amakhona angaphakathi abukhali abangela izinyembezi ezishisayo, izimbambo ezincane ezingasekelwe eziwa ngesikhathi sokutubeka, noma ukunwebeka okushisayo okungafani phakathi kwe-cobalt alloy nokufaka insimbi engagqwali. Asisho ukuthi “yebo” kuyo yonke imidwebo—sibuza ukuthi “Yimiphi imithwalo ebonwa yilokhu? Ithini imodi yokwehluleka?” Bese silungisa isango, silungise izikhuphukeli, noma siphakamise indlela ye-hybrid cast-and-brazed.
Iphampu eyodwa yase-Europe i-OEM idizayine kabusha i-nozzle geometry yayo ngemva kwempendulo yethu yokwenziwa—inqamula isivuno sokusakaza sisuka ku-68% siye ku-94%, futhi sasusa imisebenzi emibili yokugaya yangemuva kokusakazwa. Izindleko ngengxenye ngayinye zehle ngo-22%. Isikhathi sokuhola sinciphile sisuka emavikini ayi-14 saya kwayi-9.
Ukukhetha i-Micro Investment Casting Factory Kusho Ukukhetha Uzakwethu Wenqubo
Imboni ethembekile yokufaka utshalomali oluncane iletha okungaphezu kokuhambisana kwe-dimensional. Iletha ukungaguquguquki kwe-metallurgical kuwo wonke ama-500-piece batches. Iphethe u-Ra 0.8 µm kumabhore angaphakathi ngaphandle kokucija okwesibili. Ilandelela yonke igremu ye-T800 alloy ibuyele kulogi yayo encibilikayo—hhayi nje i-ID yeqoqo. Iqinisekisa izivumelwano zokuhlola ngokumelene ne-ASME Y14.5 ne-EN ISO 1101, hhayi nje amanothi e-PO yekhasimende.
I-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela ngoba amasistimu asebenza ngomfutho ophakeme we-hydraulic, amathuluzi kawoyela asogwini lolwandle, kanye namawintshi ezimoto athuthukisiwe abekezelela ukungasebenzi kahle. Uma ingxenye yakho ilawula ukugeleza koketshezi ku-valve engaphansi kolwandle, "ukuvala ngokwanele" akukho.
Bheka izilawuli zenqubo ezibhalwe phansi—hhayi izincwajana. Cela isampula yemibiko ye-CMM enama-callout e-GD&T. Cela ubufakazi bekhono lokwelapha ukushisa kwangaphakathi ngesitifiketi sesithando somlilo. Qinisekisa ukuthi bangabanikazi belebhu yabo yegobolondo noma i-outsource slurry prep. Futhi hlola njalo ukusabela kwabo ku-prototype encane egijima ngaphambi kokuzibophezela kuvolumu.
Ikusasa lingelezimboni eziphatha ukutshalwa kwezimali okuncane njengokuziphatha okuqhutshwa yi-physics—hhayi umsebenzi wokwehlisela phansi. Lokho kusho ukuthi i-R&D ejulile ibe izinhlelo zokuthulula ezinezinxushunxushu eziphansi, ukubikezela kokukhubazeka kwegobolondo elisizwa yi-AI, kanye nezinqubo eziyingxubevange ezihlanganisa ukufakwa kokutshalwa kwezimali nokuncibilika kwe-laser okukhethekile kuzici ezincanyana kakhulu. Uma iphrojekthi yakho elandelayo idinga ukunemba kokwenziwa kwezingxenye ezincane lapho i-microstructure, i-geometry, nomsebenzi kungaxoxiswana ngakho—qala ngenqubo eqinile, hhayi nje inani.
