CBN vs. PCD: ʻO ke kaua o nā mea hana ʻoki ʻoki ʻoi loa - He Luʻu hohonu i ka hana ʻana a me ka hana
CBN (Cubic Boron Nitride) Nā Mea Hana ʻoki ʻoki CNC
ʻO CBN, a i ʻole Cubic Boron Nitride, kahi mea synthetic i ʻike ʻia no kona paʻakikī loa a me ka lōʻihi. ʻO ia ka lua o ka daimana ma ke ʻano o ka paʻakikī, e lilo ia i mea kūpono no ka ʻoki ʻana i nā mea hana i hoʻohana ʻia i ka mīkini hana kiʻekiʻe. Hoʻohana maʻamau ʻia nā mea ʻoki ʻoki CBN no ka mīkini ʻana i nā kila paʻakikī, nā hao hao, a me nā mea ikaika ʻē aʻe i paʻakikī ke hana me nā mea hana ʻoki maʻamau.
Kaʻina hana o nā mea hana CBN:
ʻO ka hana ʻana o nā mea ʻoki ʻoki CBN e pili ana i ka synthesis o ka boron nitride (BN) ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka wela kiʻekiʻe. Hoʻomaka ke kaʻina hana me ka pauka boron a me ke kinoea nitrogen, i hoʻopaʻa ʻia i nā kūlana koʻikoʻi (ma luna o 1500 ° C) e hana i nā kristal cubic boron nitride (c-BN). Hoʻohui ʻia kēia mau crystals me kahi mea matrix, pinepine i ka cobalt binder, e hana i kahi hoʻokomo ʻokiʻoki a mea hana paha. Hāʻawi kēia hui ʻana i ka mea hana CBN me kona ʻano paʻakikī a me ke kūpaʻa ʻaʻahu.
Hiki ke hana ʻia nā mea hoʻokomo CBN i nā ʻano like ʻole a me nā nui, e pili ana i nā koi machining kikoʻī. Hoʻopili pinepine ʻia ka mea hana hope loa, lepo, a uhi ʻia no ka hoʻomaikaʻi hou ʻana i kāna hana a me ka hoʻopau ʻana i luna. ʻO ka hiki i ka mea hana ke mālama i nā kihi ʻoki ʻokiʻoki i nā wela kiʻekiʻe he koho maikaʻi loa ia no nā noi kaumaha ma nā ʻoihana e like me ka aerospace, automotive, a me ka hana ʻana i nā mea hana.
PCD (Polycrystalline Diamond) Nā Mea Hana ʻoki ʻoki CNC
ʻO PCD, a i ʻole Polycrystalline Diamond, kahi mea i hana ʻia e ka hoʻopaʻa ʻana i nā kristal daimana maikaʻi ma lalo o ke kaomi kiʻekiʻe a me ka mahana, e loaʻa ai kahi mea paahana ikaika a paʻa. ʻIke ʻia nā mea hana PCD no ko lākou pale ʻana i ka lole, ʻoiai ke hana ʻana i nā metala non-ferrous e like me ka aluminika, ke keleawe, a me ke keleawe, a me nā mea hana.
Kaʻina hana o nā mea hana PCD:
Hoʻomaka ka hana ʻana i nā mea hana PCD me ka hana ʻana i nā pauka daimana maikaʻi, i hui pū ʻia me kahi mea hoʻopaʻa metala, maʻamau ka cobalt a i ʻole nā pauka metala ʻē aʻe. Hoʻopiliʻia kēia huiʻana i kahi kaʻina hana wela kiʻekiʻe, kiʻekiʻe i kapaʻiaʻo "sintering" i kahi paʻi kūikawā. I loko o kēia kaʻina hana, hui pū nā kristal daimana, hana i kahi ʻano polycrystalline paʻa.
Hana ʻia nā mea hana PCD i ʻelua ʻano nui: monolithic a brazed. Ma ke ʻano monolithic, hana ʻia ka mea hana holoʻokoʻa mai PCD, ʻoiai ma ke ʻano brazed, hoʻopili ʻia kahi ʻāpana lahilahi o PCD i kahi substrate carbide. Ma hope o ka sintering, hoʻoheheʻe ʻia nā mea hana PCD i nā ana kikoʻī, e hōʻoiaʻiʻo ana i ka ʻoki ʻoki ʻana a me ka hoʻopau ʻana o ka ʻili. Hiki ke mālama houʻia lākou me nā pale e hoʻonui i ko lākou kū'ēʻana i kaʻaʻahu a me ka oxidation, hiki ke hoʻonui i kā lākou hana ma nā noi kiko'ī.
Hoʻohana maʻamau ʻia nā mea hana PCD no nā hana ʻoki kikoʻī kiʻekiʻe a ʻoi aku ka maikaʻi no ka hana ʻana i nā mea mīkini e hoʻohana nui ai i nā mea hana kuʻuna. Ma muli o ko lākou ʻano paʻakikī a me nā waiwai friction haʻahaʻa, hāʻawi lākou i ka hana koʻikoʻi i ka hoʻopau ʻana a me nā hana mīkini kiʻekiʻe.

Nā ʻokoʻa nui:
Maikaʻi Mea:
Ua kūpono ʻo CBN no nā mea paʻakikī a paʻakikī e like me nā kila paʻakikī a me ka hao.
He kūpono ka PCD no nā mea palupalu e like me ka aluminika, ke keleawe, a me nā composites, e hoʻopau koke i nā mea hana kuʻuna.
Hana i nā Mahana Kiʻekiʻe:
Hiki i nā mea hana CBN ke kū i nā mahana kiʻekiʻe me ka hoʻohaʻahaʻa ʻole ʻana, e hana maikaʻi iā lākou no nā kūlana machining kiʻekiʻe a me ka wela.
ʻO nā mea hana PCD, ʻoiai paʻakikī loa, ʻaʻole hiki ke hoʻomanawanui i nā wela kiʻekiʻe loa a hiki ke nalowale i ko lākou ʻaoʻao ma lalo o ia mau kūlana.
Noonoo Kumukuai:
ʻOi aku ka maʻalahi o nā mea hana CBN ma mua o nā mea hana PCD, no ka mea, koi ʻia ka PCD i nā kaʻina hana paʻakikī a ʻoi aku ka pipiʻi o ka mea maka.
Hoʻopau ʻili a me ka pololei:
ʻOi aku ka maikaʻi o nā mea hana PCD no ka hoʻokō ʻana i ka hoʻopau ʻana o ka ʻili maikaʻi loa, ʻoi aku hoʻi i nā mea non-ferrous.
ʻO nā mea hana CBN, ʻoiai pololei, ʻoi aku ka maikaʻi i ka lōʻihi a me ka ʻoki ʻana i ka paʻakikī ma mua o ka loaʻa ʻana o ka hopena kiʻekiʻe loa i nā mea palupalu.
Hāʻawi nā mea ʻoki ʻoki ʻo CBN a me PCD CNC i ka hana ʻokoʻa, akā mālama lākou i nā pono machining like ʻole. He kūpono nā mea hana CBN no nā mea paʻakikī, paʻakikī a me nā noi wela kiʻekiʻe, ʻoiai nā mea hana PCD e ʻālohilohi ana i ka wā e hana ai me nā metala palupalu a me nā mea hoʻohui, e hāʻawi ana i ke ola mea hana lōʻihi a me ka hana ʻoki maikaʻi loa. ʻO ke koho ʻana ma waena o nā mea ʻelua e pili ana i ka mea kikoʻī e mīkini ʻia, ke ola mea hana pono, a me ka ʻenehana mīkini.
