Ke hōʻike nei nā ʻenekinia i nā ʻāpana no nā ʻōnaehana hydraulic a i ʻole nā hui pume puʻu kiʻekiʻe, ʻo "ka hale hana hoʻoheheʻe kila" ʻaʻole ia he huaʻōlelo ʻimi wale nō - he koi hiki ʻole ke kūkākūkā. ʻO ke kūpaʻa ʻana ma lalo o ke kaʻa kaʻa wela. ʻO ka pono microstructural ma hope o ka mālama wela. ʻO ka pau ʻana o ka ʻili e ola ana i ke kahe abrasive. ʻAʻole kēia mau hoʻomanawanui; he mau paepae hemahema. Ua ʻike mākou i nā mea kūʻai aku e hōʻole i nā pūʻulu hana holoʻokoʻa no ka mea he 0.015 mm deviation i loko o ka hale pahu piston pump cylinder i hoʻoulu i ka luhi i ka cavitation-induced ma 3,200 psi. ʻO ia ke kumu o ka loaʻa ʻana mai kahi hale hana hoʻoheheʻe kila pololei ʻoi aku ka nui ma mua o ka hōʻoia ʻana o ISO - koi ʻo ia i ka hoʻopaʻi metallurgical i hōʻoia ʻia, ka ikaika metrology i loko o ke kaʻina hana, a me ka hōʻoia hana - ʻaʻole wale ka hoʻokō dimensional.
No ke aha ʻo Cobalt-Nickel Alloys e wehewehe ai i ka Benchmark
ʻO ka hapa nui o nā hale hana hoʻoheheʻe kila pololei e mālama i ke kila kila 316 a i ʻole ASTM A108. He liʻiliʻi nā mea hao kobalt-nickel haku — ʻoi aku ka AMS 5387 a me nā mea papa T800 — kahi i ʻoi aku ka paʻakikī o ka mīkini ma mua o HRC 45 a me nā coefficients hoʻonui wela e koi i ka uku hoʻoemi sub-micron casting shrinkage. Ma nā hoʻolālā honua maoli, ua ʻike mākou ua haki nā hale hoʻoheheʻe one maʻamau no nā ʻāpana pamu AMS 5387 i ka wā o ka nitriding inā ʻaʻole i hoʻomalu ʻia ke ʻano o ka palaoa i ka ASTM E112 Level 7. Hoʻopaʻa kā mākou hui i kēlā me kēia huila cobalt me ka kānana spectrographic *ma mua o ka pani ʻana o ka mold—a me ka nānā ʻana i nā hoʻokaʻawale lima dendrite e kūʻē i ka hoʻohālikelike ʻana. ʻAʻole kēia he manaʻo. ʻO ia ka mea e mālama ai i nā nozzles cobalt alloy e hana ana i nā mahina he 18 i loko o nā pūnāwai ʻawaʻawa ʻawaʻawa me ka ʻole o ka erosion grooving.
ʻAʻole ʻo ka Hoʻohui Kūʻē Kūʻē he Buzzword—He laina ola Dimensional
ʻO ka hoʻolei ʻana i waho, a laila machining, a laila hana ka mālama wela i ʻekolu kumu kūʻokoʻa o ka hewa kumulative. He 0.05 mm ka nui o ka hoolei one i lilo i 0.08 mm ma hope o ka wili ʻana o CNC—a me 0.12 mm ma hope o ka hoʻoluliluli ʻana i ke kaumaha—koe naʻe ke noho nā kaʻina hana a pau ma lalo o ka hale hoʻokahi me nā kuhikuhina datum. Ma kā mākou hale Qingdao, hōʻoia ka CMM like i ka geometry e like me ka hoʻolei ʻana, nā ana i hoʻopau ʻia, a me nā kāhea GD&T hope loa me ka hoʻohana ʻana i ka calibration probe like a me nā mea hoʻopaʻa wela. Ua ana mākou a hiki i ka 40% ʻoi aku ka paʻa o ka hoʻomanawanui kūlana ma luna o ka ʻenekinia kaʻa winch center shaft rollers i ka wā e hana ʻia ai ka mīkini ma nā hoʻoheheʻe ʻana i mahana mai ka haʻalulu—no ka mea, hoʻemi ka hoʻomanaʻo wela i ka microstructure i ka hana hou. ʻO ia ka hoʻohui kūʻokoʻa e hāʻawi ana i ke kūpaʻa ʻana o ke ana-ʻaʻole ka ʻōlelo kūʻai.
Ka Mana Pono e pane i nā nīnau maoli—ʻaʻole wale nā papa inoa
"Ua nānā ʻoe iā ia?" ʻo ia ka nīnau hewa. ʻO nā mea kūpono: *ʻO ka papa hea o ka ʻili hoʻoheheʻe i hōʻoia ʻia no ka hoʻokomo ʻana i ka ʻike? Ua nānā ʻia ka ʻili o ka lua koʻikoʻi ma ka pitch 0.1 mm—a i ʻole i hōʻike ʻia ma nā helu 5? Loaʻa i kāu moʻolelo hiki ke loaʻa ka helu pōʻaiapuni o ka umu ahi no ka pūʻulu i mālama ʻia i ka wela? Loaʻa i kēlā me kēia puʻupuʻu puʻupuʻu i ka metala ʻāpana piha ma ka ʻili hoʻopaʻa. Loaʻa i kēlā me kēia hoʻolei kila kuhili ʻole i ka hoʻāʻo ʻelua-frequency eddy i kēia manawa no ka porosity lalo-ʻaʻole wale ke komo i ka wai. A ʻae — mālama mākou i nā palapala hōʻoia maka, nā palapala hoʻomaʻamaʻa wela, a me nā hōʻike CMM no 10 mau makahiki. No ka mea, i ka pau ʻana o kahi kumu pāpaʻi ma 12,000 mau hola, "mākou i hahai i ke kaʻina hana" ʻaʻole e hoʻomaka hou i ka hana. Loaʻa ka traceability.
Ke koho ʻana i kāu hale hana hoʻoheheʻe kila pololei—He aha ka mea e hoʻoneʻe ai i ka nila
E nānā i nā palapala i hala. E noi i nā hōʻike o nā mea ʻekolu: ʻO ka mea mua, hōʻoia i ka hiki i loko o ka hale no kāu huila kikoʻī—noi i nā hōʻike hoʻāʻo no kāu papa kikoʻī (e laʻa, T800, ʻaʻole "kobalt-based"). ʻO ka lua, e nīnau pehea lākou e hōʻoiaʻiʻo ai i ke kūpaʻa dimensional *ma hope o ka pau ʻana—e ana paha lākou ma 20°C, 25°C, a me 30°C e hoʻohālike i ka hoʻoheheʻe wela o ka honua maoli? ʻO ke kolu, e hōʻoia inā loaʻa i kā lākou loiloi GD&T ka simulation hana - ʻaʻole wale ka hoʻopaʻa ʻana i ka hoʻomanawanui. Ua kōkua mua mākou i kahi OEM ʻEulopa e hōʻemi i ka leaka valve ma 68% ma ka hoʻoponopono ʻana i ke kihi kiʻi kiʻi kiʻi e hoʻokomo i ka springback post-machining i ke apo noho. Loaʻa kēlā ʻike mai ka holo ʻana i ka FEA ma ka geometry as-cast — ʻaʻole mai kahi papa inoa loiloi kiʻi. ʻAʻole wehewehe ʻia ka pololei e ka heluhelu micrometer. Ua wehewehe ʻia e ke ʻano o ka hana ʻana o ka ʻāpana i ka wā i hoʻokomo ʻia, kaomi ʻia, a me ke kaʻa. E koho i ka hoa nāna e ana ʻelua.
