Nā Hiʻohiʻona Hana Kūikawā o nā PCBN Composite Inserts

1. Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka hoʻohana ʻana

ʻAhahui Pcbn Hōʻike nā mea hoʻokomo i kahi microhardness o 2700-5000 HV, ʻo ka lua wale nō i ka daimana a ʻoi aku ka kiʻekiʻe ma mua o ka silicon carbide a me ka alumini oxide. ʻO ko lākou kūpaʻa ʻana i ka ʻaʻahu he 50 mau manawa ʻoi aku ka nui ma mua o nā mea hana carbide, 30 mau manawa ʻoi aku ka nui ma mua o nā mea hana carbide i uhi ʻia, a he 25 mau manawa ʻoi aku ka nui ma mua o nā mea hana seramika. ʻO kēia ka mea e kūpono loa ai lākou no ka mīkini ʻana i nā ʻāpana hana paʻakikī kiʻekiʻe, e hopena ana i ka maikaʻi o ka ʻili a hoʻomaʻalahi nui i nā kaʻina hana mālama wela.

2. Kūlana Kemika Maikaʻi Loa

PCBN Hōʻike nā mea hana i ke kūpaʻa kupaianaha i nā wahi e hiki ana i nā mahana o 1200–1300°C, e kūʻē ana i nā hopena waikawa a me ka alkali, e kūpono ai lākou no ka hana ʻana i nā metala ferrous.

3. Kūlana Kiʻekiʻe Loa o ke Ana Wela

PCBN Hiki i nā mea hana ke kū i nā mahana o 1400–1500°C, kokoke i ka pālua o ke kūpaʻa wela o ke daimana. He kūpono lākou no ka mīkini wikiwiki o nā superalloys a me nā kila paʻakikī, me nā wikiwiki ʻoki ʻana he 4 a 6 mau manawa wikiwiki ma mua o nā mea hana carbide.

4. Ka Hoʻokele Wera Kiʻekiʻe

Me ka conductivity thermal ʻelua wale nō i ka daimana, ʻoi aku ka maikaʻi o ka CBN ma mua o ka carbide. ʻO kēia pono hoʻoili wela i hoʻonui ʻia e hōʻemi i ka mahana ma ka ʻāpana ʻoki, a laila e hoʻolōʻihi i ke ola o ka mea hana.

5. Ka helu haʻahaʻa haʻalulu

ʻOi aku ka haʻahaʻa o ke koina friction ma waena o PCBN a me nā mea like ʻole ma mua o ke carbide, e emi ana i ka piʻi ʻana o ka wikiwiki o ka ʻoki ʻana. ʻO ka hopena, ua emi ka ikaika ʻoki a ua hoʻemi ʻia ka hoʻopili ʻana o ka chip.

Nā Hoʻohana Nui o nā Hoʻokomo Composite PCBN

Nā ʻano kūikawā o PCBN e hoʻolilo iā ia i koho kiʻekiʻe loa no ka mīkini ʻana i nā mea paʻakikī, ʻoi aku hoʻi no ka ʻoki pololei wikiwiki. Hoʻopili kona noi i nā ʻoihana like ʻole, me ka hana ʻana i nā kaʻa, ka aerospace, a me nā mīkini kaumaha.

• Ka Hoʻolaha ʻOihanaʻO ka ʻoihana kaʻa he 50.37%, nā mīkini kaumaha he 20.74%, a me ka hana pamu no 8.89%.
• Ka Hoʻolaha MeaʻO ke kila i hoʻopau ʻia he 65%, ʻoiai ʻo ka hao i hoʻolei ʻia he 28%.
• Nā Hana MīkiniʻO nā hana hoʻohuli he 60%, me ke ʻano hana ma 32.5%.
• Nā Noi Hoʻololi50% o ka hoʻohana ʻana o PCBN no ka hoʻololi ʻana i ka wili ʻana, 30% no ka hoʻololi ʻana i nā mea hana carbide.

Eia kekahi laʻana, mai ka hoʻolauna ʻana Nā Hoʻokomo Pcbn I ka makahiki 2005 no ka mīkini ʻana i nā disc brake hao i hoʻolei ʻia, ua ʻike ʻo Beijing West Industries i ka wikiwiki o ka ʻoki ʻana i pāpālua ʻia ma mua o nā mea hana keramika, me ke ola o ka mea hana e hoʻolōʻihi ʻia ana i 3 a 4 mau manawa, e hoʻonui nui ana i ka pono hana a me ka hoʻemi ʻana i nā kumukūʻai.

Koho a me ka Hoʻolālā Kūpono

PCBN He loea loa nā mea hana, e koi ana i nā ʻano hana like ʻole e pili ana i nā mea hana a me nā ʻano hana. ʻO ke kiʻekiʻe o ka ʻike CBN, ʻoi aku ka nui o ka paʻakikī o ka mea hana, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka conductivity thermal. Ma ke ʻano maʻamau, ua hoʻokaʻawale ʻia i ka ʻike CBN kiʻekiʻe, waena, a me ka haʻahaʻa, ua hoʻolālā ʻia kēia mau mea hoʻokomo e hoʻokō i nā pono hana like ʻole.

• ʻIke Kiʻekiʻe (80%–95%)Kūpono no ka hao i hoʻolei ʻia, ka hana ʻana i ka pauka, a me nā superalloys.
• ʻIke Waena (60%–80%): Kūpono no ka mīkini hana kaumaha o ke kila i hoʻopau ʻia.
• ʻIke Haʻahaʻa (40%–60%)ʻOi aku ka maikaʻi no ka mīkini hoʻomau māmā wikiwiki.

Wahi a nā koi pololei a me ka maikaʻi o ka ʻili, loaʻa nā ʻāpana CBN i nā nui coarse, medium, a me nā nui maikaʻi e hoʻokō ai i nā koi hana like ʻole.

Me kona mau hiʻohiʻona hana kūikawā, ʻo Boreas' PCBN ʻO nā mea hoʻokomo composite e kū nei ma ke ʻano he koho kūpono no ka hana ʻana i nā mea paʻakikī. E koho iā Boreas no kāu mau pono PCBN a hoʻokiʻekiʻe i kāu hana hana me ka hoʻemi ʻana i nā kumukūʻai. E ʻike i ka maikaʻi a me ka hilinaʻi o kā mākou huahana a hui pū me ka nui o nā mea kūʻai aku māʻona e hilinaʻi nei iā Boreas no kā lākou mau hoʻonā mīkini. E ʻae iā mākou e kōkua iā ʻoe e hoʻokō i ka maikaʻi loa i kāu mau hana—e kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou PCBN nā mōhai!
