ʻAʻole hoʻomaka ka hoʻonā ʻenehana mīkini electrochemical pololei me nā kikoʻī mea hana - hoʻomaka lākou me kahi ʻāpana * ʻaʻole ʻoki ʻia *, * ʻaʻole paʻa i ka hoʻomanawanui * a i ʻole * ʻaʻole ola i ka lawelawe *. Ua ʻike pinepine mākou: nā hale pahū cobalt-nickel e haki ana ma lalo o 300-bar cyclic pressure; AMS 5387 nozzles hiki ʻole ke hana hou ʻia ma hope o ka mālama ʻana i ka wela; T800 nā huila huila waena waena e ʻaʻahu like ʻole i loko o 200 mau hola hana. ʻAʻole kēia nā hemahema hana. He ʻano like ʻole ia o ke kaʻina hana—a ke kūʻai nei lākou i ka manawa, ka ʻōpala, a me ka hilinaʻi.
I ka wā e paʻa ai ka mīkini hana maʻamau i kona palena, e piʻi ana ka mīkini electrochemical pololei
ʻAʻole ʻo Electrochemical machining (ECM) he "CNC maikaʻi aʻe." He kaʻina hana ʻokoʻa ʻē aʻe i pili i ka physics-no-contact, ʻaʻohe mea paahana, zero mechanical stress. ʻO ia ka mea nui ke wehe ʻoe i nā mea mai nā superalloy paʻakikī e like me ka cobalt-chrome a i ʻole ka nickel-based Inconel ʻokoʻa kahi e hoʻoulu ai ka wili kuʻuna i nā micro-cracks, burrs, a i ʻole ke koʻikoʻi tensile koena ma ka ʻili. Ma ko mākou hale hoʻokō ISO ma Qingdao, hoʻohana mākou i ka ECM ʻaʻole ma ke ʻano he hana kūʻokoʻa—akā, ma ke ʻano he hopena i hoʻopili ʻia i loko o kahi kaila hana metala pololei piha. Hoʻohana mākou ia mea no ka hoʻopau ʻana i nā ʻāpana koʻikoʻi o loko o nā hale pahu pahu piston pump kahi hiki ʻole i nā wili hope ke hiki, e hoʻopau i nā noho valve kaomi kiʻekiʻe me ka hoʻololi ʻole ʻana i nā callout GD&T, a e hoʻokō i ka ± 0.01 mm ka mānoanoa o ka paia ma waena o 360° o kahi huila winch center shaft roller—kekahi mea e wili ana e hana hou i nā holo ʻana.
Eia naʻe ka mea e nānā ʻole ai ka hapa nui o nā mea kūʻai: ʻo ka holomua o ka ECM ma muli o ka mīkini a ʻoi aku ma luna o ʻekolu mau mea hoʻokomo i hoʻopili paʻa ʻia - ka hoʻokumu ʻana o ka electrolyte, ka hoʻolālā cathode, a me ka mana o ka manawa maoli. ʻO ka cathode i kuhi hewa ʻia ke kumu o ka taper; ʻO kahi electrolyte i hoʻokuʻu ʻole ʻia e neʻe i ka pH a hoʻopau i ka pau ʻana o ka ʻili; hana ʻole ka holo ʻana o ka velocity i ka lua kūloko. Hoʻopaʻa mākou i kēlā me kēia hoʻonohonoho kūʻē i nā ʻāpana kūʻai maoli - ʻaʻole nā coupon hoʻāʻo. No ka laʻana, i ka wā e makemake ai ka OEM hydraulic ʻEulopa i nā ākea slot 0.05 mm i hoʻopaʻa ʻia i nā plug AMS 5387, ua holo mākou i 12 mau hoʻāʻo me ka optical profilometry a me ka cross-section metallography-ʻaʻole wale i ka CMM scans-e laka i ka mahana electrolyte, voltage ramp rate, a me inter-electrode gap ma mua o ka holo mua ʻana.
No ke aha e lanakila ai ka Vertical Integration i nā hale kūʻai "ECM-Whenly" no nā ʻāpana koʻikoʻi o ka Misiona
Ke kūʻai aku nei kekahi mau mea kūʻai iā ECM ma ke ʻano he lawelawe. Hoʻokomo mākou iā ia i loko o nā kahe hana hoʻolei-a-hoʻopau-no ka mea, hiki mai nā hemahema ECM nui loa * ma mua o ka pā ʻana o ka ʻāpana i ka ʻauʻau electrolyte. ʻAʻole maikaʻi ka microstructure as-cast? Porosity kokoke i kahi ili hoʻopaʻa koʻikoʻi? Kūlike ʻole ka ʻai ʻana ma T800 alloy? Hoʻonui ʻia kēlā mau hemahema i ka wā ECM, ʻaʻole huna. ʻO ia ke kumu e hana ai kā mākou hale hana electrochemical machining ma lalo o hoʻokahi hale me ka hoʻolei kālā, multi-axis CNC, a me ka mālama wela i hōʻoia ʻia. Mālama mākou i ke kaulahao holoʻokoʻa: hiki ke ʻike i nā mea maka (nā ʻāpana cobalt-nickel a pau i hoʻokumu ʻia me nā palapala wili), nā pōʻai hoʻoluhi koʻikoʻi ma mua o ka mīkini ʻana, a me ka passivation post-ECM a i ʻole electropolish i hoʻohālikelike ʻia i ka pale ʻana i ka corrosion - ʻaʻole wale nā mea nani.
Hana pū mākou iā GD&T ʻaʻole ma ke ʻano he pepa—akā ma ke ʻano he palapala ʻāina paʻa. Ke nānā nei mākou i nā kaha kiʻi no nā kiwi puʻupuʻu, hōʻailona mākou i nā ʻāpana kahi e paio ai nā ʻae ʻana o ka ʻaoʻao (e. Ma kahi o ka hōʻole ʻana i ka paʻi, manaʻo mākou i nā ʻano hoʻohālikelike: mīkini paʻakiki me CNC, a laila ECM ka 0.15 mm hope loa e paʻi i ke ʻano maoli a me ka pololei o ka ʻili. Hoʻokiʻoki ia i ka manawa pōʻai e 37% me ka all-ECM i ka wā e hālāwai ana i nā koi ASME B16.34.
ʻO ka hōʻoia ʻana o ka honua: He aha ka hana (a ʻaʻole)
Nīnau kā mākou mea kūʻai i ʻekolu nīnau ma mua o ka hoʻokō ʻana iā ECM:
- "Hiki iā ʻoe ke hoʻopaʻa i ka ± 0.005 mm ma kahi lua o loko 200 mm anawaena?" ʻAe—inā ʻae ka ʻāpana geometry i ke kahe electrolyte like ʻole a paʻa paʻa ka cathode. Hana mākou i kēia i kēlā me kēia lā ma nā kumu puna no nā noi ʻaila a me nā kinoea waho.
- "He aha ka liʻiliʻi liʻiliʻi o ka hiʻohiʻona āu e hana pono ai?" 0.12 mm mau puka i loko o nā nozzles kobalt alloy, i hōʻoia ʻia me ka metrology SEM—ʻaʻole i ʻike ʻia.
- "Ke kākoʻo nei anei ʻoe i nā ʻāpana maʻamau ʻole e like me T800?" ʻAe. Akā makemake mākou i ka hoʻohui kemika piha a me ka mōʻaukala mālama wela ma mua. Me ka ʻole o ia mea, lilo nā hoʻoponopono kemika electrolyte i mea koho—a piʻi ka nui o ka ʻōpala.
Hōʻole mākou i ka 11% o nā RFQ mua—ʻaʻole ma muli o nā āpau o ka hiki, akā no ka mea, ʻo ka ʻāpana geometry a i ʻole ke kūlana waiwai e hoʻohālikelike ai i ka ECM. ʻOi aku ka maikaʻi o ka ʻōlelo ʻana "ʻaʻole" ma mua o ka hāʻawi ʻana i kahi ʻāpana i hala i ka nānā ʻana akā hāʻule i ka hoʻāʻo ʻana.
Ke nānā nei i mua: ʻAʻole pololei ka pololei—ʻaʻole hoʻi kā mākou kaʻina hana
ʻO ka hiki ʻana o ka hale hana mīkini hana electrochemical pololei maoli ke ʻano o ka ulu ʻana ma mua o ka pololei o ke ana i loko o ka alignment hana hana. I kēia manawa, ke koho nei mākou i nā ʻāpana pulsed-ECM no ka hoʻomaikaʻi ʻana i ka ʻoi o ka lihi ma nā ʻaoʻao aʻa o ka turbine blade—a me ka hoʻohui ʻana i nā ʻenekona conductivity inline no ka hoʻoponopono ʻana i ke kahe electrolyte i ka wā holo lōʻihi. Ke hoʻonui nei mākou i ka ʻae ʻana o NADCAP ʻaoʻao ʻekolu no ka hōʻoia ʻana i ke kaʻina hana kikoʻī ECM, ʻaʻole wale i ka hoʻokō pono maʻamau. No ka mea ma nā ʻāpana like aerospace hydraulics a i ʻole subsea pumping, ʻaʻole i ana ʻia ka "pololei" i nā microns wale nō. Ana ʻia i ka manawa ma waena o nā hemahema. I ka uptime. Ma ka hilinaʻi.
Inā pili kāu papahana hou i nā ʻāpana cobalt-nickel, nā ʻōnaehana valve kaomi kiʻekiʻe, a i ʻole nā hiʻohiʻona superalloy maʻamau kahi i hoʻopaʻa ʻia nā ʻano hana maʻamau—hale hana mīkini electrochemical pololei pono e hoʻomohala ʻia ka ʻike mai ka lā hoʻokahi. ʻAʻole i hoʻohui ʻia ma ke ʻano he manaʻo hope.
