Kana mainjiniya achida masimbi esimbi anorarama 30,000 psi hydraulic cycles kana 650 ° C exhaust gasi kubuda, haatange negeneric foundry. Vanotanga na fekitori yakarasika wax casting services iyo inobata cobalt alloy nozzles semidziyo yekuvhiya-uye inonyatsoziva kuti AMS 5387's chimiro chezviyo chinopindura sei kuvhunduka kwekupisa panguva yekudonha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imwe fekitari yakadaro. Kwete broker. Kwete kambani yekutengesa. Maoko-pa, ISO-inoenderana oparesheni muQingdao uko mametallurgists anogadzirisa slurry viscosity zvichibva pane ambient humidity-uye machinists re-zero shanu-axis spindles vasati vacheka T800 cobalt-based shafts kune offshore winch masisitimu. Isu takaona vatengi vachirasikirwa nemavhiki matatu uye zviuru gumi nezvisere zvemadhora mukugadzirisa zvakare nekuti mupi wavo wepakutanga akasvetuka pre-cast GD&T kusimbiswa. Panzvimbo iyi, njodzi yedimensional inobatwa isati yekutanga wakisi patani yaoma.
Maitiro avo akarasika ekukanda wakisi hakusi "kukanda mari." Iyo yakanyatsobatanidzwa system: certified raw material traceability → ceramic shell formulation yakagadzirirwa yakakwirira-alloy thermal expansion → inodzorwa dewaxing ramp rates → vacuum-inobatsira kudururwa kwe superalloy pa ± 5 ° C kushivirira → post-cast stress relief yakarongedzerwa kuAMS 2750E standards. Pamavharuvhu ekumanikidza kana piston pombi humburumbira, zvinoreva kuti kukora kwemadziro kunoramba kuri pasi pe ± 0.15 mm—kunyangwe pa420 mm OD inokandwa ine migero yekutonhodza yemukati. Hapana kufungidzira. Hapana batch-to-batch drift. Yese inopisa yakawanda inotakura yakazara spectrographic mishumo uye tensile test zvitupa.
Chii chinovaparadzanisa kubva kune standard foundries? Zvinhu zvitatu zvinoshanda:
- Alloy chirango-kwete chete kugona. Havana "kubata" cobalt-nickel alloys. Vanomhanyisa nzvimbo dzakatsaurirwa dzevira dzeAMS 5387, dzine macrucibles akasiyana, ladles, uye slag-inobata maprotocol ekudzivirira kusvibiswa kwemuchinjiko nemagiredhi asina tsvina. Kana mutengi akatumira dhirowa kune isiri-standard cobalt alloy plug ine 0.05 mm positional kushivirira pazviteshi zvitanhatu zvakarukwa, timu haina kutaura nemapofu. Vakamhanyisa musangano wekuseka-wax, yekumisikidzwa kwegedhi kuburikidza nekuyerera, uye yakasimbisa nguva yekutsva kwegoko-vasati vabvumidza iyo PO.
- Hapana handoffs pakati pekukanda uye machining. Vazhinji vatengesi vanoburitsa CNC basa mushure mekukanda. Pano, mainjiniya emhando imwechete anosaina pane ese-akakanda pamusoro pekupedzisira (Ra ≤ 3.2 μm) uye yekupedzisira machined datum (CMM-yakasimbiswa kusvika ± 0.01 mm). Izvo zvinobvisa zvikanganiso zvekuisa-up kana uchitenderedza pombi inokwirisa flange uye kubereka mune imwe setup-yakakosha kune hydraulic seal kutendeseka.
- Kutadza-modhi yekuziva yakavakirwa mune yega nhanho. Pamasimbi uye simbi isina tsvina inoshandiswa mumidziyo yemafuta negasi, vanoongorora mukati memvura *mushure me* kupfurwa kuputika asi *vasati vagadzira*—kubata micro-shrinkage porosity iyo kugaya kungavharika. Kana chikamu cheT800 alloy chikaratidza subsurface oxide inclusions pasi pe ultrasonic scan, inoraswa-kwete "kugadziriswazve." Nekuti mumishoni-akakosha maapplication, "yakanaka zvakakwana" inokundikana chinyararire - uye nenjodzi.
Vamwe vanogona kukakavara kuti kukanda jecha kunopa kukurumidza kutendeuka kune hombe simbi. Asi kana chikamu chacho chiri winch centre shaft roller inoshanda pasi pe cyclic torsional mutoro, geometry kutendeka kunokosha kupfuura kumhanya. Wakisi yakarasika inoburitsa padhuze-mambure maumbirwo ane madziro asina kudhirowa, achibvisa chipiri machining pane dzakakosha kubereka nzvimbo. Uye hongu-inodhura zvakanyanya kumberi. Asi mutengi mumwe akadzikisa mutengo wakakwana pavharuvhu ne22% mushure mekuchinja: mashoma magungano akarambwa, zero minda inodonhedza, uye hupenyu hwesevhisi hwakawedzerwa kubva kumwedzi gumi nemina kuenda kumwedzi 36+ munzvimbo dzerenje-jecha.
Izvi hazvisi dzidziso. Zvinodzokororwa. Pasi yavo yekugadzira inomhanyisa maitiro akaonda ekufambisa-kwete se sirogani, asi semazuva ese maitiro. Prototypes inotakura mumazuva gumi nemaviri ekushanda. Medium-volume orders (50–500 pcs) inobata ± 3-mazuva ekutumira mahwindo-yakavimbiswa mukunyora. Kutungamira kweprojekiti kunosanganisira chaiyo-nguva yekudhirowa markup, GD&T gakava rekugadzirisa, uye manufacturability mhinduro mukati memaawa makumi mana nemasere ekutumirwa kweRFQ. Hapana chirevo chebhokisi-dema. Kwete "tichazvinzwisisa gare gare." Kungogadziriswa kweinjiniya kubva pazuva rekutanga.
Tichitarisa kumberi, tarisiro inorodza: kudzika R&D kuita yakasanganiswa yekukandira-machining sequences kune ekupedzisira-yakatetepa-yakavakirwa pombi dzimba, yakawedzera chitupa chekubvumidzwa kwezvinhu zvemuchadenga-giredhi, uye kubatanidzwa kwakasimba kwe-in-process yekupisa yekufungidzira panguva yekupfura goko. Asi musimboti unoramba usina kushanduka-tsanangudzo yavo yechokwadi fekitori yakarasika wax casting services hazvisi zvemichina specs. Zviri pamusoro pekuve nemhedzisiro yeese micrometer, zvese zvinosanganisirwa, zvese kupisa kutenderera. Nokuti kana chikamu chako chabata marita 5 000 emvura yegungwa—kana kuti kudzora kufamba kwemafuta muturbine—fekitari yaunosarudza haipi simbi. Inopa chivimbo.
