Ke hoʻololi nei i ka pono o ka ʻoki ʻana: Polycrystalline Cubic Boron Nitride (PCBN)
ʻO nā papa hui polycrystalline cubic boron nitride (PCBN) he mau mea ʻoki hana kiʻekiʻe i ʻike ʻia no ko lākou paʻakikī koʻikoʻi, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka conductivity thermal maikaʻi loa. ʻO kēia mau waiwai e kūpono ai ka PCBN no ka mīkini pololei o nā mea paʻakikī e like me nā keramika, nā kila paʻakikī, a me nā mea hao paʻakikī. Ke hoʻohālikelike ʻia me nā mea ʻoki kuʻuna, Nā Mea Hana Pcbn hāʻawi i ka pololei ʻokiʻoki kiʻekiʻe a me ka pono, e hoʻonui nui ana i ka huahua a lilo i waiwai nui i ka ʻoihana hana.
Papa Hoʻohuihui PcbnUa kūkulu ʻia nā s me kahi substrate alloy paʻa paʻa, i hoʻopaʻa ʻia me ka cubic boron nitride (CBN) micro-powder, a ua sintered ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi. Loaʻa iā CBN kahi paʻakikī ʻelua ma hope o ke daimana, me ke kūpaʻa wela a me ke kūpaʻa kemika i ʻoi aku ma mua o nā daimana, e lilo ana ia i mea hoʻokūkū ikaika i ka mīkini ʻana i nā metala hao. Hoʻonoho kēia iā PCBN ma ke ʻano he koho koʻikoʻi i nā noi abrasive a me nā mea hana ʻoki.
ʻO ka hoʻolālā kūikawā o nā papa hui PCBN ʻaʻole wale nō e hāʻawi i ka paʻakikī kūikawā a me ke kūpaʻa wela akā hoʻonui pū i ka paʻakikī ma o ka substrate alloy paʻakikī, e hoʻomaʻalahi ana i ka hana hou aku. He ākea kā lākou noi, e uhi ana i nā mīkini CNC holomua, nā mīkini hana piha piha, a me nā laina hana wikiwiki. Hoʻohana nui ʻia ʻo PCBN i ka mīkini ʻana i ke kila paʻakikī, ka hao i hoʻolei ʻia i ke anu, nā kila mea hana, a me nā ʻāpana i hoʻopaʻa ʻia, e pani mālie ana i nā alloys paʻakikī kuʻuna a me nā mea hana keramika a puka mai ma ke ʻano he ʻano nui i ka ʻoihana mea hana ʻoki.
1. Ke Kūlana Hoʻomohala o kēia manawa o nā Papa Hui PCBN
ʻOi aku ka holomua o ka hoʻomohala ʻana o nā mea hana PCBN ma nā wahi e like me ʻEulopa, ʻAmelika ʻĀkau, a me Iapana, kahi i hoʻokumu ʻia ai kahi ʻōnaehana loea makua. Hoʻomaopopo nui ʻia nā huahana e ka diversification, ka hoʻonui ʻana i ka maikaʻi, a me ka hana like. ʻO nā papa composite PCBN mai nā ʻāina ʻē he paʻa mau i nā diameters ma luna o 50mm, me Element Six e hāʻawi ana i nā huahana me nā diameters o 57mm a me 101.6mm o nā kino sintered CBN maʻemaʻe (AMB90), e mālama ana i kahi ʻokoʻa o ka hana a me ka thermal i loko o 30% no ke kūlike kūikawā. Hāʻawi ʻo DI lāua ʻo Sumitomo i nā kikoʻī o 50.8mm, 58mm, a me 64mm, kēlā me kēia.
Ua hoʻomohala kūleʻa ʻo Boreas i nā papa composite PCBN 64mm ke anawaena ma hope o nā makahiki o ka noiʻi ʻana, me nā nui o nā ʻāpana mai 2μm a 15μm. Hāʻawi mākou ma mua o 20 mau ʻano like ʻole o nā hoʻonā i hoʻopilikino ʻia e hoʻokō i nā pono mīkini kikoʻī. Ma ke koho ʻana i nā papa composite PCBN a Boreas, e ʻike ʻoe i kahi hoʻonui nui i ka pono o ka ʻoki ʻana a me ka maikaʻi!
