Ke hāʻule kāu ʻōnaehana hydraulic ma lalo o ke kaomi 350-bar, a i ʻole ka pahu pahu pahu pahu cobalt-alloy ma hope o 472 mau hola hana, ʻaʻole hiki ke hoʻomaka ka pilikia ma ka hui ʻana. Hoʻomaka ia ma mua—ma ke koho ʻana i nā mea, ka wehewehe GD&T, a i ʻole ka ʻoki mua ʻana ma ka mīkini CNC multi-axis. ʻO ia ke kumu ʻaʻole ʻimi wale nā ʻenekinia ma ʻAmelika ʻAmelika a me ʻEulopa i nā "lawelawe machining CNC." Huli lākou i a kiʻekiʻe precision machining hale hana e mālama ana i ke kūpaʻa dimensional e like me ka huaʻōlelo aelike—ʻaʻole he manaʻo.
ʻAʻole nā hale kūʻai hoʻomanawanui paʻa e lawelawe i nā superalloys like
Ua ʻike ʻelua mākou i kēia makahiki: ua loaʻa i ka OEM mana wai Tier-1 nā hale hoʻoheheʻe kobalt AMS 5387 me nā koina Cpk ma luna o 1.67 ma nā anawaena o waho-akā ua ʻike ʻia nā microcracks ma hope o ke kaʻa kaʻa wela. Ke kumu kumu? Ua hoʻohana ka mea hoʻolako i nā mea hana carbide maʻamau me ka nānā ʻole ʻana i ka ukana wela i ka wā o ka roughing. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Mīkini mākou i nā ʻāpana T800 me ka hoʻohana ʻana i nā mea hoʻokomo PCD cryogenically cooled a me ka mana hānai adaptive. ʻO kēlā me kēia ʻoki ʻoki lāʻau spindle torque, kahe wai hoʻoheheʻe, a me ka hoʻohana ʻana i nā mea hana - ua hoʻopili ʻia nā ʻikepili i kā mākou waihona hōʻoia hōʻoia kūloko. ʻAʻole kēia i ka ʻenehana nui. Pēlā ʻoe e paʻa ai i ka ± 0.005 mm ma ka hale pahu piston pump cylinder 210-mm-diameter me ka mālama ʻana i ka pono o ka hale palaoa ASTM E112.
ʻO kā mākou mea hoʻokō ISO ma Qingdao e holo like ana i ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana i nā kaʻina hana - ʻaʻole nā limalima. Hele pololei nā mea hao mai ka lulu ʻana i nā umu hoʻoluʻu kaumaha, a laila i loko o nā kikowaena mīkini paʻa me ka hoʻopili ʻana. ʻAʻohe hoʻoponopono hou. ʻAʻohe ʻōnaehana hoʻonohonoho hou ʻana. Pēlā mākou e hāʻawi ai i nā kumu pahū me ka palahalaha ma lalo o 0.012 mm ma waena o 1,200 mm—a e hoʻouna iā lākou i loko o 18 mau lā ma hope o ke kiʻi ʻana.
ʻO ka hoʻohui pololei ʻana, ʻaʻohe manaʻo e pili ana i ka metallurgy
ʻO kekahi mau mea hoʻolako i waho o ka hoʻolei ʻana, a laila kūʻai mai i nā kaola maka mai nā hale wili. Hoʻomohala pū mākou i nā mea kikoʻī me nā mea hana alloy i hōʻoia ʻia. Ke noi ka mea kūʻai i nā pahu kobalt-nickel no ka lawelawe kinoea ʻawaʻawa, hōʻoia mākou i kēlā me kēia wela e pili ana i ka ASTM A494 Grade CW6MC-ʻaʻole i ka ikaika tensile wale nō, akā ke kūpaʻa intergranular corrosion no ka NACE MR0175/ISO 15156 Annex A. He hōʻailona kila kila QR-coded i hoʻopili ʻia i kēlā me kēia kumu hoʻolei, pili i nā hōʻike loiloi spectral, nā moʻolelo moʻolelo wela, a me nā faila nānā hope CMM.
Hōʻike kēia aʻo i kahi mea nui loa: ka hana hana. ʻO kahi huila winch center shaft i hana ʻia mai ka 42CrMo4 maʻamau—i hana ʻia a hiki i ka ISO 2768-mK tolerances, paʻakikī a hiki i 52 HRC, a laila hoʻopaʻa ʻia i Ra 0.4 µm—ua ola ʻo 14,000 pōʻai ma luna o kahi pahu hoʻāʻo kaʻa ʻenekinia me ka ʻole o ka hoʻololi ʻana o ka noho. Ua hāʻule nā ʻāpana hoʻokūkū ma ka pōʻai 8,920. ʻokoʻa? Hoʻohana kā mākou laina lapaʻau wela i nā umu i hoʻopaʻa ʻia me ka ± 2°C like, ʻaʻole i nā umu puʻupuʻu me nā gradients ± 15°C.
Hoʻomaka ka hana honua maoli ma mua o ka lele ʻana o ka chip mua
"Hiki iā ʻoe ke hana i kēia?" ʻo ia ka nīnau hewa. ʻO ka pololei: "He aha ka mea e haki mua ai - a pehea mākou e hoʻōki ai?" I ka wā o ka loiloi ʻenekinia, hōʻailona mākou i nā kelepona GD&T e kūʻē ana me nā kaohi ʻana ma ka wili 5-axis. Manaʻo mākou i nā kihi kikoʻī ma nā hiʻohiʻona hoʻoheheʻe ʻia e hōʻemi ana i ka wehe ʻana o ka waihona ma hope o ka mīkini e 37%. Manaʻo mākou i nā mea ʻē aʻe—e like me ka hoʻololi ʻana mai ke kila kila 1.4404 a i ka duplex 1.4462—ke ʻoi aku ka nui o ka chloride i ka 120 ppm.
- Hoʻopaʻa mākou i ke kaha kiʻi geometry e pili ana i nā ala komo mea hana - ʻaʻole nā ana inoa wale nō
- Hoʻohālikelike mākou i ka hoʻoheheʻe wela ma nā hale ʻoi aku ka paia me ka hoʻohana ʻana i SolidWorks Flow Simulation + empirical shrinkage coefficients.
- Hoʻihoʻi mākou i nā PDF i hoʻopaʻa ʻia i loko o 48 mau hola-ʻaʻole nā leka uila "hōʻoia kūpono".
ʻAʻohe prototype e hele i ka metala me ka ʻole o kahi hōʻike DFM i kau inoa ʻia. ʻAʻole no ka mea makemake mākou i ka pepa. No ka mea, he $28,000 ke kumukūʻai o ka hoʻokuʻu ʻana i ka hana hou i ka wā e pono ai ke kino valve non-standard i ʻekolu mau hoʻolālā hou.
ʻAʻole i hoʻohiki ʻia ka hilinaʻi. Ana ʻia, hoʻopaʻa ʻia, a hoʻouna ʻia
Loaʻa i kēlā me kēia hoʻouna kahi palapala hōʻoia me ka ʻikepili metrology piha: CMM point clouds no nā lua koʻikoʻi, optical profiler scans no ka sila ʻana i nā ʻili, nā palapala ʻāina paʻakikī ma nā wahi wela. ʻAʻole mākou e ʻōlelo "meets spec." Hōʻike mākou i ka *pololei* kahi i loaʻa ai ka 0.008 mm deviation—a no ke aha i pili ʻole ai ia hana (e laʻa.
ʻO ia ke ʻano o kā mākou mālama ʻana> 99.2% ka lawe ʻana i ka manawa no nā kauoha medium-volume-ʻoiai me ka 2024's titanium alloy supply volatility. Hoʻopaʻa kā mākou kahe hana lean i ka WIP ma ka pae kahua. Inā paʻi ka nozzle kobalt alloy i ka bottleneck i ka poli ʻana, hoʻomaka ka hoʻolālā hana ʻana i ka hoʻihoʻi hou ʻana i nā cell lua-ʻaʻohe pono e piʻi.
A kiʻekiʻe precision machining hale hana loaʻa ka hilinaʻi ʻaʻole ma o nā palapala, akā ma o ka mea e ola ana i ka hoʻohana ʻana i ke kahua: e hoʻopaʻa mau ana nā pahu kaomi i ka 22 makahiki, ʻo AMS 5387 mau ʻāpana pamu e holo ana ma nā kahua o waho me ka ʻole i hoʻolālā ʻole ʻia, nā ʻāpana T800 e paʻa ana i ka hoʻomanawanui ma hope o 15 mau pōʻai wela. Loaʻa kēlā kūlike mai ka mālama ʻana i kēlā me kēia ʻāpana e like me ke komo ʻana i kahi ʻōnaehana koʻikoʻi ola-no ka mea pinepine, ʻo ia.
Inā koi kāu papahana aʻe i ka sub-10-micron e hoʻihoʻi hou ʻia i nā ʻāpana paʻakikī i ka mīkini-a inā ua ʻoki ʻoe i ʻelua mau pūʻulu prototype e alualu ana i ka GD&T hoʻokō-e hoʻomaka me ke kaʻina hana, ʻaʻole nā kumu kūʻai. ʻAʻole ʻoki wale ka hoa kūpono. Hoʻopau lākou i nā ʻano hemahema ma mua o ke kau ʻana i ke kauoha.
