Mea hana ʻoki CBNspili i kahi ʻano mea hana ʻokiʻoki superhard, i hana ʻia me ka hoʻohana ʻana i ka ʻenehana kiʻekiʻe kiʻekiʻe a me ka ʻenehana kiʻekiʻe e hoʻohana ana i ka pauka CBN ma ke ʻano he mea maka a me kahi mea liʻiliʻi.Ma muli o ka paʻakikī kiʻekiʻe o nā mea ʻoki ʻoki CBN, kūpono loa ia no ka hana ʻana i nā mea me ka paʻakikī i ʻoi aku ma mua o ka HRC50 a me ke kūpaʻa ikaika.
He aha ka CBN？
ʻO CBN (cubic boron nitride) he mea hana paʻakikī loa i kūkulu ʻia ma hope o ke daimana hana, i hoʻololi ʻia mai ka hexagonal boron nitride (graphite keʻokeʻo) ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi.ʻO ka CBN he mea hao hao ʻole, a ʻo kona paʻakikī ka lua ma mua o ke daimana, ʻoi aku ka kiʻekiʻe ma mua o ke kila kiʻekiʻe a me ke kila paʻakikī.No laila, ma hope o ka hana ʻia ʻana i mea hana, ʻoi aku ka maikaʻi o ka CBN no ka hana ʻana i nā mea paʻa me nā mea ʻoki carbide.
He aha nā meaʻoki CBN mea paahanakūpono no ka hana?
Hiki ke hoʻohana ʻia nā mea ʻoki ʻoki CBN e ʻoki i nā mea e like me ke kila paʻakikī (ke kila, ke kila kila, a me nā mea ʻē aʻe). ke kila kiʻekiʻe, ka paʻa paʻa, ka wela wela, a me nā mea ʻē aʻe, a loaʻa iā ia nā pōmaikaʻi nui i ka hana metala ferrous.
Pono e hoʻomaopopo ʻia inā he metala palupalu a i ʻole non-metallic ka mea hana, ʻaʻole kūpono nā mea hana ʻoki CBN no ka hana ʻana.Manaʻo ʻia nā mea hana ʻoki CBN i ka wā i hiki ai ka paʻakikī o ka mea i kahi pae (HRC>50).
maʻamauHoʻokomo CBN nā ʻano hana
ʻO ka ʻōlelo maʻamau, ʻo nā mea hana maʻamau i hoʻohana ʻia i ka hoʻohuli ʻana i ka mīkini ka nui o nā ʻano hana penei: hoʻokomo CBN hoʻokomo a hoʻokomo CBN welded, ma waena o ka hoʻokomo CBN welded me ka hoʻokomo welded integral a me ka hoʻokomo welded composite.
(1) Hoʻokomo CBN hoʻohui.Hoʻopili ʻia ka ʻili holoʻokoʻa mai ka pauka micro CBN, me nā ʻoki ʻoki he nui.Hiki ke hoʻohana ʻia nā ʻōlelo aʻoaʻo o luna a me lalo no ka ʻoki ʻana, e hopena i ka hoʻohana nui ʻana o ka blade blank.A he kiʻekiʻe ke kulou ʻana o ka pahi a hiki ke kū i ka ʻoki ʻoki kiʻekiʻe me ka hohonu o ka ʻokiʻoki nui, kūpono no ka hoʻomau ʻana, nāwaliwali intermittent, a me nā kaiapuni ʻoki intermittent ikaika.Loaʻa iā ia ka hoʻohana ākea a hiki ke hoʻokō i nā koi o ka mīkini paʻakikī, semi precision, a me ka pololei.
(2) Hoʻokomo ʻia ʻo CBN i hui pū ʻia.ʻO ke kino holoʻokoʻa hoʻoheheʻe ʻia he ikaika kuʻihao kiʻekiʻe a me ka hoʻonohonoho ʻana o ka lua waena, hiki ke hoʻololi pololei i ka hoʻokomo ʻana.He kūpono no nā kūlana mīkini me ka hohonu o <2mm, nāwaliwali intermittent a me ka hoʻomau ʻana i nā kaiapuni mīkini, e hoʻokō i nā pono o ka semi precision a me ka mīkini pololei.
(3) Hoʻokomo CBN welded hui.Ma hope o ka ʻoki ʻana, hoʻopaʻa ʻia nā poloka CBN composite liʻiliʻi ma luna o kahi substrate paʻa paʻa e hana ai i nā ʻāpana ʻokoʻa a me nā lau ʻoluʻolu.ʻO ka maʻamau, hoʻokahi wale nō ʻaoʻao i loaʻa, hoʻohana nui ʻia no nā kūlana machining precision.
I kēia manawa, hoʻohana nui ʻia nā mea ʻoki ʻoki CBN ma ka ʻāina a me ka honua, ʻoi aku hoʻi no ka ʻoki ʻana i nā mea mīkini paʻakikī i nā ʻoihana e like me ka hana automotive (engines, crankshafts, brake discs, brake drums, etc.), mining machinery (rolling mortar walls, rolling mortar walls). slurry pumps, etc.), ʻoihana ʻoihana halihali (hub bearings, slewing bearings, wind power bearings, gears, etc.)
