Ke hōʻike ʻia e nā ʻenekinia hale hana hoolei aniani wai ʻO nā lawelawe no nā ʻāpana metala kūpaʻa kiʻekiʻe, ʻaʻole lākou e ʻimi wale ana i kahi foundry-ke ʻimi nei lākou i ka mana dimensional, microstructural consistency, a me ka hilinaʻi metallurgical ma lalo o ke kaomi. Ua ʻike mākou i nā papahana he nui i hoʻopaneʻe ʻia e nā manaʻolana like ʻole: kahi ʻāpana i hala i nā loiloi dimensional akā ʻaʻole i holo kaʻa kaʻa wela, a i ʻole kahi hale hoʻoheheʻe cobalt e kū ana i nā ʻae paʻi akā nahā i ka wā o ka hoʻāʻo hydraulic. ʻO ke kumu kumu? Māmā ʻāpana—nā hale kūʻai me ka mana ʻole o ka mīkini, nā hale kūʻai mīkini me ka ʻole o ka ʻike, a i ʻole nā mea hoʻolako e mālama iā AMS 5387 a i ʻole T800 ma ke ʻano he kumu maʻamau ma mua o nā mea koʻikoʻi.
No ke aha he mea nui ka hoʻolei ʻana i ke aniani wai—a no ke aha ʻaʻole i hana pololei ʻia
ʻO ke aniani wai (sodium silicate) hoʻopukapuka kālā e hāʻawi i nā ʻae ʻoi aku ka paʻakikī ma mua o ka hoʻolei ʻana i ke one a me ke kumu kūʻai haʻahaʻa haʻahaʻa ma mua o ka pūpū seramika no nā mea ʻenehana paʻakikī, medium-volume. Akā ʻo ka kūleʻa e pili ana i ʻekolu mau mea kūʻai ʻole: ka hoʻomalu ʻana i ka rheology slurry, ka dewaxing i hoʻomalu ʻia e pale aku i ka pohā ʻana, a me nā ʻaoʻao o ka umu ahi i hoʻopaʻa ʻia i ka pihi hoʻonui wela o kēlā me kēia alloy. Ma kā mākou hale kūʻai, hoʻoponopono mākou i nā ratio binder-to-powder i ka manawa maoli e pili ana i ka haʻahaʻa ambient-ʻaʻole mai kahi pepa SOP static. No nā ʻāpana kobalt-nickel e like me AMS 5387, ʻo ka hoʻokaʻawale ʻana i ka 2°C i ka wā preheat hiki ke hoʻoulu i ka micro-shrinkage i loko o nā hale pāpaʻi lahilahi. ʻO ia ke kumu e nānā ai mākou i kēlā me kēia hehee me nā ʻāpana ʻelua-thermocouple a hoʻopaʻa i ka mōʻaukala wela no kēlā me kēia ʻāpana-ʻaʻole i kēlā me kēia pūʻulu.
ʻAʻole he huaʻōlelo ka hoʻohui kū pololei—ʻo ia wale ke ala e paʻa ai iā GD&T
Hiki ke lawe ʻia ka ± 0.1 mm ka hoʻomanawanui laina i ke kino o ka pahu kaomi i hoʻolei ʻia i loko o ke aniani wai—akā, inā ʻaʻohe manaʻo pololei mai ka hana hoʻoheheʻe ʻana i ka hana CNC e hoʻoheheʻe ana i kona alo e hoʻopaʻa ʻia, e alualu ʻoe i ka holo ʻana ma waena o nā hoʻonohonoho ʻelima. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ka hoʻolei ʻana, ka mālama ʻana i ka wela, a me ka machining multi-axis kaʻana like i hoʻokahi keʻena metrology. Hoʻopaʻa kā mākou CMM i ka geometry as-cast ma mua o ka hana ʻino; hōʻoia nā profilometers i ka pololei o ka ʻili ma hope o ka hala hope; a ʻo kēlā me kēia hale pahu pahu piston pump e hoʻāʻo hydrostatic hana ma ka 1.5x helu ʻana i ke kaomi hana—ʻaʻole wale ka nānā leak. Hoʻopau kēia i ka handoff "pahu ʻeleʻele" ma waena o nā keʻena. I ka wā i hoʻouna mai ai kahi mea kūʻai mai iā mākou i kahi kaha kiʻi GD&T no ka ʻenekini kaʻa winch center shaft roller, ua hōʻailona mākou i ʻelua mau helu helu i kūʻē me ke kuhikuhi huki kumu—ma mua o ka hoʻomaka ʻana o ka mea hana. Ua mālama ia i ʻekolu pule a me $18,000 i ka hana hou.
Hoʻokaʻawale ka hoʻopaʻi ʻana i ka waiwai i ka hoʻolei pololei ʻana mai ka hana huahana
ʻAʻole e hāʻule nā nozzles Cobalt alloy ma muli o ka maikaʻi ʻole o ka mīkini. Hāʻule lākou ma muli o ka hāʻawi like ʻole ʻana o ka carbide ma ka ʻāpana keʻa. Hoʻokumu mākou i nā ingots T800 a me AMS 5387 me nā palapala wili piha—me ka nānā ʻana i nā spectrographic, nā hōʻike nui o ka palaoa, a me nā pihi tensile no ASTM E8. Hoʻokaʻawale ʻia kēlā me kēia wela, hōʻailona ʻia me nā kāleka traceability QR-coded, a mālama ʻia i loko o nā pā i mālama ʻia i ke aniau. Inā hōʻike kekahi pūʻulu i ka maʻiʻo sulfur kiʻekiʻe ma luna o 0.015%, ua hoʻokaʻawale ʻia - ʻaʻole i hoʻohaʻahaʻa ʻia. No ke aha mai? No ka mea, hoʻoulu ʻia ka sulfur i nā ʻāpana kobalt ma nā palena o ka palaoa, e hoʻolalelale ana i ka hoʻomaka ʻana o ka luhi ma nā kaiapuni pume. ʻAʻole mākou e hālāwai wale i nā kikoʻī - palapala mākou i nā ʻano mea e pili ana i nā kūlana koʻikoʻi o ka noi. ʻO ia ke ʻano o kā mākou hāʻawi ʻana i nā plugs e ola ana ma mua o 12,000 mau kaʻina i loko o nā ʻāpana ʻaila a me nā ʻea kinoea.
ʻO ka hāʻawi ʻana i ka honua maoli ʻo ia hoʻi nā manawa wānana-ʻaʻole nā ʻōlelo hoʻohiki
ʻAʻohe manaʻo o "ka manawa alakaʻi" me ka ʻole o ka pōʻaiapili. He 12 pule no 50 mau kumu pahū kila kila e manaʻo ana i ka loaʻa ʻana o ka waiwai maka, ka hoʻonohonoho ʻana i ka umu ahi, a me nā pōʻai ʻae ʻōlelo mua-ʻaʻole nā lā alemanaka wale nō. Kūkulu mākou i nā papa manawa e pili ana i ka nui o ka bottleneck. ʻAʻole mākou e hoʻopaʻa puke. Akā, hoʻopololei mākou i nā hana prototype me nā holo hana—no laila e hōʻoia kāu mau ʻāpana mua 5 i nā kaʻina hana a me nā koina nānā ma mua o ka hoʻonui ʻana. Hōʻike nā mea kūʻai ma ʻAmelika ʻĀkau a me ʻEulopa i ka awelika o ka lawe ʻana i ka manawa ma 98.3% i nā mahina he 18 i hala iho nei - ʻaʻole no ka wikiwiki mākou, akā no ka hoʻolālā ʻana i hope mai ka hoʻāʻo hana, ʻaʻole i mua mai ke komo ʻana i ke kauoha. A i ka wā e hele ai kahi hoʻololi hoʻolālā i waena o ka holo? Holo hou mākou i ka FMEA—ʻaʻole e hoʻohou i ka BOM.
Inā makemake ʻoe i kahi hale hana hoolei aniani wai e mālama ana i kāu puʻupuʻu puʻupuʻu a i ʻole ka hale pahū piston ma ke ʻano he ʻōnaehana-ʻaʻole he ʻāpana-pono ʻoe i ka mana i hōʻoia ʻia ma luna o ka hana alloy, ka hoʻomau ʻana o ke kaulahao dimensional, a me ka hōʻoia ʻana i ka honua maoli. Hoʻomaka kēlā me ka nīnau ʻaʻole "Hiki iā ʻoe ke hoʻolei?" akā "Pehea ʻoe e hōʻoiaʻiʻo ai i ka hana?"
