ʻO ke kaʻina hana ʻokiʻoki ma kahi o 90% o ka hana machining.ʻO ka mea hana ka "niho" o ka mīkini mīkini hana, e pili pono ana i ka pae hana o ka ʻoihana hana.ʻO ka ʻoki ʻana e pili ana i ka ʻoki ʻana i nā mea nui mai ka ʻili o ka mea hana, e hōʻoia i ka geometry workpiece, dimensional accuracy, surface quality a me nā ʻano ʻē aʻe o nā koi hoʻolālā o ke ʻano machining, e helu ana ma kahi o 90% o ka hana machining holoʻokoʻa.Hoʻokō pinepine ʻia ka ʻoki ʻana e ka ʻoki ʻana i nā mea mīkini, a ʻo ka mea paahana ke kī nui o nā mea hoʻohana, ʻoiai ʻo nā "niho" o nā mea hana mīkini ʻenehana, pili pono kona maikaʻi i ka hana ʻana o ka pae ʻenehana hana mīkini, hana pono a me ka maikaʻi o ka huahana.ʻO ka ʻoki ʻana i nā mea hana i luna no nā mea hoʻolako maka, hoʻohana ʻia i lalo i nā ʻoihana hana nui.E lawe i ka mea hana carbide nui loa e like me ka laʻana, e like me nā mea i hana ʻia e hiki ke hoʻokaʻawale ʻia i: ke kila, ke kila kila, ka hao, ka metala non-ferrous, ka hao wela, ke kila paʻakikī, etc. tungsten carbide, cobalt pauka, tantalum niobium solid solution, etc.) nā mea hana, ʻo ke kahua noi i lalo i hoʻopaʻa ʻia i ka ʻoihana hana, hoʻohana nui ʻia i nā kaʻa a me nā kaʻa, nā mīkini mīkini, nā mīkini maʻamau, ka ʻeleʻele, nā mīkini ʻenekinia a me nā māla ʻē aʻe, aerospace, ʻO ka pūʻali koa, nā mīkini lapaʻau a me nā ʻoihana ʻē aʻe e hāʻawi i kahi noi ʻenehana ākea a me kahi wahi hoʻololi no nā mea hana carbide.
He aha nā ʻano o nā mea hana ʻoki carbide?
1.high hardness: Carbide mea hana i hana 'ia i ka carbide me ka paakiki kiʻekiʻe a me ka heheʻe wahi (i ikeia ka paakiki manawa) a me ka mea hoʻopaʻa metala (ʻikeʻia he binding phase) ma ka pauka metallurgy method, kona paakiki he 89 ~ 93HRA, oi aku mamua o kiʻekiʻe holo kila. , ma 5400C, hiki i ka paakiki ke hiki i 82 ~ 87HRA, a me ke kila kiʻekiʻe māmā lumi wela paakiki (83 ~ 86HRA) like.
2. Ka ikaika kulou a me ka paʻakikī: ʻo ka ikaika kulou o ka paʻakikī paʻakikī maʻamau i ka laulā o 900 ~ 1500MPa.ʻOi aku ka kiʻekiʻe o ka maʻiʻo o ka pae hoʻopaʻa metala, ʻoi aku ka kiʻekiʻe o ka ikaika kulou.Ke like ka mea hoʻopili, YG(WC-Co).ʻOi aku ka kiʻekiʻe o ka ikaika o ka alloy ma mua o YT (WC-Tic-Co) alloy, a emi ka ikaika me ka hoʻonui ʻana o ka ʻike TiC.ʻO ka paʻa paʻa he ʻano mea brittle, ʻo kona hopena paʻakikī i ka lumi lumi he 1/30 ~ 1/8 wale nō o HSS.
3. ʻAʻahu maikaʻi ke kūpaʻa.ʻO ka wikiwiki o ka ʻoki ʻana o ka mea hana carbide he 4 ~ 7 mau manawa kiʻekiʻe ma mua o ke kila kiʻekiʻe, a ʻo ke ola mea hana he 5 ~ 80 mau manawa kiʻekiʻe.ʻO ka hana ʻana i nā mea hana, ke ana ʻana i nā mea hana, ke ola ma mua o ke kila kila kila 20 ~ 150 mau manawa kiʻekiʻe.Hiki ke ʻoki i ka 50HRC a i ʻole mea paʻakikī.
