He aha nā ʻano o nā mea hana ʻoki carbide?
ʻO nā mea hana carbide, ʻoi aku ka nui o nā mea hana carbide hiki ke kuhikuhi ʻia, nā huahana alakaʻi o nā mea hana mīkini CNC. Mai ka 1980s, ua hoʻonui ʻia nā ʻano mea hana carbide paʻa a hiki ke kuhikuhi ʻia, a i ʻole nā mea hoʻokomo, i nā ʻano hana like ʻole. Nā mea hana, hoʻohana i nā mea hana carbide hiki ke hoʻonui ʻia mai nā mea hana maʻalahi a me nā mea ʻoki wili i mua i ka pololei, paʻakikī, a me nā mea hana hana. No laila, he aha nā ʻano o nā mea hana carbide?
1. ʻO ka paakiki kiʻekiʻe: Ua hana ʻia nā mea hana ʻoki carbide i hoʻopaʻa ʻia i ka carbide me ka paʻakikī kiʻekiʻe a me ka helu heheʻe (i kapa ʻia ʻo ka pae paʻakikī) a me ka mea hoʻopaʻa metala (i kapa ʻia ʻo ka hoʻopaʻa ʻana) ma ke ʻano o ka pauka metallurgy, a ʻo kona paʻakikī ʻo 89 ~ 93HRA, ʻoi aku ka kiʻekiʻe ma mua o kēlā ke kila kiʻekiʻe, ma 5400C, hiki i ka paʻakikī ke hiki i ka 82-87HRA,ʻo ia ka mea like me ke kila kiʻekiʻe ma ka mahana wela (83-86HRA). ʻOkoʻa ka paʻakikī o ka carbide i hoʻopaʻa ʻia me ke ʻano, ka nui, ka nui o ka palaoa a me ka maʻiʻo o ka pae hoʻopaʻa metala, a e emi iho me ka hoʻonui ʻana o ka maʻiʻo paʻa metala. Me ka maʻiʻo adhesive phase like, ʻoi aku ka paʻakikī o ka YT alloy ma mua o ka YG alloy, ʻoiai ʻo ka alloy i loaʻa iā TaC (NbC) ʻoi aku ka paʻakikī i ka wela kiʻekiʻe.
2. Ka ikaika kulou a me ka paʻakikī: ʻO ka ikaika kulou o ka carbide cemented 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 maʻiʻo paʻa, YG(WC-Co). ʻOi aku ka kiʻekiʻe o ka ikaika o ka mea hao ma mua o ka YT (WC-Tic-Co), a ke emi nei ka ikaika me ka piʻi ʻana o ka ʻike TiC. ʻO ka carbide Cemented kahi mea palupalu, a ʻo kona ʻano paʻakikī i ka wela lumi he 1/30 a 1/8 wale nō o HSS.
3. ʻAʻahu maikaʻi ke kūpaʻa. ʻO ka wikiwiki o ka ʻoki ʻana o nā mea hana carbide cemented he 4 ~ 7 mau manawa kiʻekiʻe ma mua o ke kila kiʻekiʻe, a ʻo ke ola mea hana he 5 ~ 80 mau manawa kiʻekiʻe. No ka hana ʻana i nā mold a me ke ana ʻana i nā mea hana, ʻo ke ola lawelawe ʻo 20 a 150 mau manawa ʻoi aku ka lōʻihi ma mua o ke kila kila. Hiki iā ia ke ʻoki i nā mea paʻakikī ma kahi o 50HRC.
Ka hoʻohana ʻana i nā mea hana carbide: hoʻohana mau ʻia nā mea hana carbide i nā kikowaena mīkini CNC, nā mīkini engraving CNC. Hiki ke hoʻokomo ʻia ma luna o ka mīkini wili maʻamau e hana i kekahi mau mea paʻakikī paʻakikī a paʻakikī ʻole.
I kēia manawa, ʻo nā mea hana hana o nā mea i hoʻohui ʻia, nā plastics ʻoihana, nā mea plexiglass a me nā mea metala non-ferrous ma ka mākeke, ʻo ia nā mea hana carbide āpau, nona nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ke kūpaʻa paʻa, ka paʻakikī maikaʻi, ka wela a me ka pale ʻana i ka corrosion. A me kahi pūʻulu o nā waiwai maikaʻi loa, ʻoi aku kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, ʻoiai inā mau ka loli ʻole ma kahi mahana o 500 °C, aia nō ka paʻakikī kiʻekiʻe ma 1000 °C.
Hoʻohana nui ʻia ʻo Carbide ma ke ʻano he mea paahana, e like me ka huli ʻana i nā mea hana, nā mea ʻoki wili, nā mea hoʻolalelale, nā drills, nā mea hoʻoluliluli, a me nā mea ʻē aʻe, no ka ʻoki ʻana i ka hao, nā metala non-ferrous, plastics, nā fiber kemika, graphite, aniani, pōhaku, etc. hiki ke hoʻohana ʻia ke kila no ka ʻoki ʻana i ke kila wela, ke kila kila, ke kila manganese kiʻekiʻe, ke kila mea hana a me nā mea paʻakikī i ka mīkini.
