Akatswiri opanga zakuthambo akafuna zida zopangira ndalama zomwe zimakhala ndi ± 0.05 mm kulolerana pansi pa 300 MPa zonyamula ma hydraulic, sizikhazikika pazoyambitsa zolinga. Amafunafuna Aero Metals Investment Casting Factory yokhala ndi zolembedwa zazitsulo zolembedwa, zero-batch drift mu AMS 5387 cobalt alloy, ndi makina a CNC ogwirizana ndi ma callout a GD&T —osati zojambula zokha. Ndipamene kulondola kumasiya kukhala mwatsatanetsatane ndipo kumakhala njira yobwerezabwereza.
Tawona mapulojekiti ambiri akuyimitsidwa pomwe ma projekiti akudutsa macheke koma amalephera kuyendetsa njinga kutentha pa -55 ° C mpaka +120 ° C chifukwa kapangidwe ka tirigu sikunatsimikizidwe kuti kutentha kusanachitike. Kapena pamene nyumba yapampu inasweka pambuyo pa maola 420 akugwira ntchito mosalekeza-osati chifukwa cha zolakwika zapangidwe, koma kuchokera ku micro-porosity pafupi ndi malo osindikizira omwe anatsetsereka poyang'anitsitsa. Izi siziri zochitika zenizeni. Ndiwo kusiyana pakati pa "kutumizidwa" ndi "oyenerera ndege." Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kuponyedwa kulikonse kwa ndalama za cobalt-nickel kumayamba ndi ma billets ovomerezeka a T800 aloyi, omwe amatha kutsatiridwa ndi kuchuluka kwa kutentha, ndi malipoti azithunzi omwe amawunikiridwa motsutsana ndi ASTM E1096 asanasungunuke.
Malo awo ogwirizana ndi ISO ku Qingdao samayendetsa ndalama ngati mzere woyima - amawaphatikiza mwamphamvu ndi makina a ma axis asanu, kuyesa njira, komanso kuyesa kosawononga. Mwachitsanzo: bulu la AMS 5387 silimaponyedwa, kenako limapangidwa ndi makina, kenako limawunikidwa. Imaponyedwa ndi chilolezo cha makina a 0.3 mm pamalo osindikizira ovuta; kutenthedwa pambuyo kutentha mu ng'anjo vacuum amawunikidwa tsiku lililonse; zomalizitsa pogwiritsa ntchito makonzedwe a Renishaw-probed omwe amalipiritsa okha kukula kwamafuta; ndikuyang'aniridwa ndi ma Zeiss CMM omwe akuyendetsa machitidwe ogwirizana ndi ASME B89.4.10-osayesa kukula kokha, koma mawonekedwe olakwika, kukhulupirika kwapamwamba, ndi kuuma kwapafupi. Kuphatikizika koyima kumeneku kumachotsa ma handoffs pomwe milu ya kulolerana imadziunjikira. Nyumba ya silinda ya pampu ya pistoni imafika pa QA yomaliza yokhala ndi mbiri yayikulu-osati chidindo chodutsa / cholephera.
Ena anganene kuti kuponya mchenga kumapereka mwayi wokwera mtengo pamabulaketi akulu akulu. Koma pamipanda yopyapyala yokhala ndi mipanda yopyapyala, yowoneka bwino kwambiri, makamaka yomwe imafunikira njira zozizirira zamkati kapena njira zamadzimadzi zofananira, kusungitsa ndalama sikunafanane. QIANGSENYUAN imatsimikizira izi popanga zitsulo zosapanga dzimbiri zokhala ndi makulidwe a 1.2 mm, 0.8 mm mkati, ndi kumaliza pansi pa Ra 1.6 µm-monga momwe zimaperekedwa, osati zopukutidwa. Njira yawo ya zipolopolo za ceramic imagwiritsa ntchito zircon-based slurries ndi silika stucco, zomwe zimapangitsa kuti pakhale kutentha komwe kumasunga tsatanetsatane popanda kung'amba pang'ono. Ndipo mosiyana ndi masitolo omwe amamanga zipolopolo zakunja, chipinda chawo chonse cha zipolopolo chimagwira ntchito mopanda chinyezi komanso kutentha (± 2 ° C, 45-55% RH), chifukwa ngakhale kusinthasintha kwakung'ono kumasintha kutulutsa kwa zipolopolo - ndikusintha kuthamanga kwachitsulo panthawi yothira.
Zomwe zimawasiyanitsa si kuthekera kokha - ndi momwe amazigwiritsira ntchito. Pamene European hydraulics OEM imafuna matupi 27 amtundu wa valve mu T800 cobalt alloy, iwo sanangogwira mawu potengera voliyumu ya 3D. Akatswiri adawunikiranso zofotokozera za GD&T, zomwe zidawonetsa zoopsa zomwe zingasinthidwe pamakina a 0.15 mm, adapereka zosintha zazing'ono kuti apewe kugaya yachiwiri, ndikupereka malipoti oyeserera azinthu owonetsa mphamvu zolimba ≥1,380 MPa pa 650 ° C - zotsimikizika pa AMS 2269. Dongosolo lawo lokonzekera bwino limatsata dongosolo lililonse motsutsana ndi nthawi yeniyeni yozungulira - osayerekezedwa ndi maola ogwira ntchito - kotero kuti kuchuluka kwapakati (50-300 pcs) kumayenda mkati mwa masiku 12 ogwira ntchito, mosadukiza. Palibe "kutengera kupezeka kwa zinthu". N'zosadabwitsa kuti NRE imalipira chivomerezo cha nkhani yoyamba.
Ngati mukuyang'ana zida zam'mlengalenga momwe kulephera kumatanthauza kutsika kwadongosolo - kapena zoyipitsitsa - mumafunikira zambiri kuposa kuponya. Mufunika kuwongolera zitsulo, kuwunikira kofananira komwe kumafanana ndi zomwe mukufuna, komanso kulumikizana ndi uinjiniya kuchokera pakujambula pojambula pomaliza. An Aero Metals Investment Casting Factory monga QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapereka izi-osati ngati chilankhulo chotsatsa, koma monga umboni wolembedwa, ziphaso zapadera, ndi magawo omwe amagwira ntchito mofanana pamagawo onse opanga. Chotsatira sichikufanizira mawu. Ikugawana phukusi lanu la GD&T ndikufunsa kuti: "Kodi mungayembekezere kuti chiwopsezo choyamba - ndipo mumachichepetsa bwanji?" Kukambirana kumeneko kumalekanitsa ogulitsa ndi othandizana nawo.
