Pamene mainjiniya aku North America kapena ku Europe akufufuza Investment kuponya China, sakungoyang'ana kupanga zotsika mtengo-akufunafuna kukhazikika kwa dimensional pansi pa 120 MPa hydraulic pressure, microstructural consistency kudutsa 500-part batches, ndi zero kulolerana kwa porosity mu cobalt alloy nozzles. Ndicho chenicheni kumbuyo kwa funsolo. Tawonapo magulu ogula zinthu akukana ogulitsa atatu motsatizana-osati pamtengo, koma chifukwa makulidwe a khoma amasiyana ± 0.35 mm pa 42-mm-diameter piston pump silinda nyumba. Kulondola sikosankha pamakina ovala kwambiri a hydraulic. Ndilo maziko.
Chifukwa chiyani "Investing Casting China" Sikulinso Chisankho Chokha Chokha
Zaka zisanu zapitazo, "kuponya ndalama ku China" kumatanthauza kuponya mchenga ndi CNC kukhudza-ndi kukonzanso kawirikawiri. Masiku ano, zikutanthawuza zoyambira zotsimikizika za ISO 9001 zomwe zimayendetsa njira zotayika zonse: jekeseni wa sera pa ± 0.05 mm kulolerana, kuwombera zipolopolo za ceramic mpaka 1,100 ° C, kuwongolera kothandizidwa ndi vacuum, ndi chithandizo cha kutentha kwapambuyo-kuponyedwa kumatsimikiziridwa ndi kusanthula kwazithunzi. Kusinthako kunabwera kuchokera ku zofuna—osati ndondomeko. Ma Hydraulic OEM amafunikira magawo omwe amakhala ndi ma callout a GD&T ngati ⌀0.02 mm kulolerana kwa malo pa mabwana a 8 × M12- popanda makina achiwiri. Ndizotheka kokha pamene kupanga mapangidwe, kusankha aloyi, ndi uinjiniya nkhungu amakhala mu gulu limodzi luso.
Tathandizira kukonzanso kwapampu 27 komwe makasitomala amasinthiratu matupi azitsulo zosapanga dzimbiri ndi zofanana ndi ndalama. Zotsatira zake? 38% kuchepetsa kulemera kwapakati, 22% kutsika mtengo wonse pa unit, ndikuchotsa makina 3-5 a makina. Koma kupambana kudali paziwiri zomwe sizingakambirane: kutsata kwakuthupi mpaka kutentha, komanso kutsimikizira kwa CMM m'magawo atatu - osati kungoyang'ana komaliza.
Kumene Kupeza Kwambiri Kumalephera—ndi Mmene Mungapewere
Ogula ena amaganiza kuti onse ogulitsa ndalama aku China amagwiritsa ntchito ma aloyi a cobalt-nickel mofanana. Iwo samatero. AMS 5387 cobalt alloy imafuna kutsetsereka kokwanira kwamafuta panthawi yamoto wa zipolopolo. Mofulumira kwambiri? Ma Microcracks. Mochedwa kwambiri? Zotsalira za kaboni. Tawonapo kuchuluka kwa 41% pama roller apakati a T800 pomwe oyambitsa adagwiritsanso ntchito nkhungu za zipolopolo kupitilira maulendo atatu - palibe chenjezo, palibe lipoti loyambitsa.
Kukonzekera sikuli kocheperako. Kuwongolera njira zophatikizidwira: kudula mitengo yeniyeni ya pyrometer panthawi yothira, kuwunika kwapang'onopang'ono kwa mpweya m'chipinda chothira, komanso kuyesa kwamphamvu kwa batch pa kutentha kulikonse. Pamalo athu a Qingdao, malo aliwonse a AMS 5387 amapangidwa ndi zitsulo asanatulutsidwe - ngakhale ma prototypes. Osati chifukwa zolemba zimafunikira, koma chifukwa gulu limodzi lophatikizira limatha kuyambitsa kutopa pa 15,000 psi.
- Cobalt alloy nozzles: Amapangidwa kuchokera kuzinthu zopangira ndalama zokhala ndi ≤0.08 Ra pamwamba kumaliza kumaliza kusanachitike
- Ma valve opanikizika: Ponyani mu ASTM A494 CW6MC, yoyesedwa ku 1.5 × kugwira ntchito ndikuzindikira kutayikira kwa helium
- Winch center shaft rollers: Kutenthedwa mpaka HRC 52-56, kuuma komwe kumapangidwa kudutsa madera 12 ozungulira
Izi sizinthu zamakalata. Ndi mayankho omwe amapangidwa kuchokera ku kusanthula kobwerezabwereza-osati mawu ongoyerekeza.
Kuphatikiza Koyima Komwe Kumapereka Kukhazikika
Kutumiza kunja, kukonza, ndi kumaliza kwa ogulitsa kumachulukitsa chiopsezo. Kuchedwa kwa kuchiritsa zipolopolo kumakankhira CNC kukonzekera. Kuwonongeka kwapamtunda komwe kumapezeka pambuyo popukuta kukakamiza kukonzanso-kapena kupukuta. Timayendetsa onse atatu pamalo amodzi ogwirizana ndi ISO: ma cell oponyera moyandikana ndi malo opangira makina a 5-axis, okhala ndi ma lab a metrology ogawana komanso kutsatira zinthu mogwirizana.
Izi sizokhudza kumasuka. Ndizokhudza kuwongolera zosinthika zomwe zimasefukira: kutsitsa kumakhudza kukhazikika komaliza; kupsinjika kwa makina opangidwa ndi makina kumasintha kupotoza pambuyo pa kutentha; ngakhale pH yoziziritsa pogaya imasintha mbiri yotsalira munyumba zokhala ndi khoma. Gulu limodzi likakhala ndi tcheni chonse, ma callout a GD&T amakhala osasunthika kuyambira patani ya sera kupita ku bokosi lotumizira.
Mwachitsanzo: kasitomala waku Europe amafunikira mayunitsi 120 a maziko a mpope oponyedwa chitsulo ndi kusalala ≤0.1 mm kupitilira 650 mm. Opikisana nawo adalemba masabata 14. Tidapereka 9 - chifukwa mainjiniya athu opangira zida adasintha kapangidwe kake potengera kuyerekeza kwanthawi yayitali, ndipo akatswiri athu amakina adagwiritsa ntchito mawonekedwe omwewo a CMM potsimikizira nkhani yoyamba ndikuwunika komaliza. Palibe ma handoffs. Palibe kutanthauziranso.
Kusankha Bwenzi Lanu Lopanga Ndalama ku China—Zomwe Mungatsimikizire Tsopano
Osafunsa kuti "Kodi mumapanga ndalama?" Funsani m'malo mwake:
- "Ndiwonetseni maere anu atatu omaliza a AMS 5387-kuphatikiza malipoti a spectrographic, ma curve oyeserera, ndi zipika zozungulira zipolopolo."
- "Mumatsimikizira bwanji kukhazikika pakati pa kuponya ndi makina omaliza? Kodi mumagwiritsa ntchito zida zolipiridwa ndi zovuta?"
- "Kodi makulidwe anu apamwamba kwambiri a khoma pa gawo la 30 mm ndi chiyani? Ndipo mumayesa bwanji - chipolopolo cholowa, kutsanulira, kapena kumaliza?"
Mayankho enieni amavumbula kukhwima kwa ndondomeko. Zitsimikizo zosamveka sizimatero.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pomwe kulondola kumakwaniritsa kuyankha: kuyika ma geometries ovuta mu ma superalloys, kukhala ndi zololera zolimba popanda kupanga makina ochulukirapo, ndikupereka umphumphu wogwira ntchito - osati magawo okha. Mukasaka Investment kuponya China, yang'anani kupitirira kukula kwa fakitale ndi ziphaso. Yang'anani umboni wa kulephera kolamuliridwa - ndi momwe zidasinthira kuzungulira kwawo kotsatira.
