He mea maʻamau ka Graphite ʻaʻole metala, ʻeleʻele, me ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa o ka mahana, ka conductivity uila a me ka thermal maikaʻi, ka lubricity maikaʻi a me nā ʻano kemika paʻa; conductivity uila maikaʻi, hiki ke hoʻohana ʻia ma ke ʻano he electrode ma EDM. Ke hoʻohālikelike ʻia me nā electrodes keleawe kuʻuna, he nui nā pono o ka graphite e like me ke kūpaʻa wela kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa, a me ka deformation thermal liʻiliʻi. Hōʻike ia i ka maʻalahi o ka hoʻololi ʻana i ka hana ʻana o nā ʻāpana kikoʻī a me nā ʻāpana paʻakikī a me nā electrodes nui. Ua pani mālie ia i nā electrodes keleawe ma ke ʻano he mau huna ahi uila. ʻO ke kumu nui o nā electrodes machining [1]. Eia kekahi, hiki ke hoʻohana ʻia nā mea pale graphite ma lalo o nā kūlana wikiwiki, wela kiʻekiʻe, a me ke kaomi kiʻekiʻe me ka ʻole o ka ʻaila lubricating. Hoʻohana nui nā lako he nui i nā kīʻaha piston mea graphite, nā sila a me nā bearings
I kēia manawa, hoʻohana nui ʻia nā mea graphite ma nā kahua o nā mīkini, metallurgy, ʻoihana kemika, pale aupuni a me nā kahua ʻē aʻe. Nui nā ʻano ʻāpana graphite, ka paʻakikī o ke kūkulu ʻana o nā ʻāpana, ka pololei kiʻekiʻe o ka dimensional a me nā koi maikaʻi o ka ʻili. ʻAʻole lawa ka hohonu o ka noiʻi kūloko ma ka mīkini graphite. He kakaikahi nō hoʻi nā mea hana mīkini hana graphite kūloko. Hoʻohana nui ka hana graphite haole i nā kikowaena hana graphite no ka hana wikiwiki, i lilo i kēia manawa i kuhikuhi nui o ka hana graphite.
Kuhi nui kēia ʻatikala i ka ʻenehana mīkini graphite a me nā mīkini hana mai nā ʻano aʻe.
①Ka loiloi ʻana i ka hana mīkini graphite;
② Nā ana hana ʻenehana graphite i hoʻohana pinepine ʻia;
③ Nā mea hana i hoʻohana pinepine ʻia a me nā palena ʻokiʻoki i ka hana ʻana i ka graphite;
Ka loiloi hana ʻoki graphite
He mea palupalu ka graphite me kahi ʻano like ʻole. Hoʻokō ʻia ka ʻoki ʻana i ka graphite ma ka hana ʻana i nā ʻāpana ʻāpana discontinuous a i ʻole ka pauka ma o ka haki ʻana o ka mea graphite. E pili ana i ke ʻano ʻoki o nā mea graphite, ua hana nui nā loea ma ka home a me nā ʻāina ʻē i ka noiʻi. Manaʻo nā loea haole ʻo ke kaʻina hana hoʻokumu ʻāpana graphite ma kahi kokoke i ka wā e pili ana ka ʻaoʻao ʻoki o ka mea hana me ka workpiece, a ua kuʻi ʻia ka piko o ka mea hana, e hana ana i nā ʻāpana liʻiliʻi a me nā lua liʻiliʻi, a hana ʻia kahi māwae, e hoʻolōʻihi i ke alo a me lalo o ka piko o ka mea hana, e hana ana i kahi lua haki, a e haki kekahi hapa o ka workpiece ma muli o ka holomua o ka mea hana, e hana ana i nā ʻāpana. Manaʻo nā loea kūloko he maikaʻi loa nā ʻāpana graphite, a he ʻāpana piko nui ka ʻaoʻao ʻoki o ka mea hana, no laila ua like ke kuleana o ka ʻaoʻao ʻoki me ka extrusion. ʻO ka mea graphite ma kahi pili o ka mea hana - ua ʻomi ʻia ka workpiece e ka maka rake a me ka piko o ka mea hana. Ma lalo o ke kaomi, hana ʻia ka haki ʻana o ka brittle, a laila hana i nā ʻāpana chipping [3].
I ke kaʻina hana o ka ʻoki ʻana i ka graphite, ma muli o nā loli i ke kuhikuhi ʻoki ʻana o nā kihi poepoe a i ʻole nā kihi o ka workpiece, nā loli i ka wikiwiki o ka mīkini hana, nā loli i ke kuhikuhi a me ke kihi o ka ʻoki ʻana i loko a i waho o ka mea hana, ka ʻoki ʻana i ka haʻalulu, a pēlā aku, ua hoʻokumu ʻia kahi hopena i ka workpiece graphite, e hopena ana i ka lihi o ka ʻāpana graphite. ʻO ke kihi brittleness a me ka chipping, ka ʻaʻahu koʻikoʻi o ka mea hana a me nā pilikia ʻē aʻe. ʻOi loa i ka wā e hana ai i nā kihi a me nā ʻāpana graphite lahilahi a haiki, ʻoi aku ka nui o ka hana ʻana i nā kihi a me ka chipping o ka workpiece, ka mea i lilo i mea paʻakikī i ka mīkini graphite.
Kaʻina hana ʻoki graphite 
ʻO nā ʻano hana mīkini kuʻuna o nā mea graphite e komo pū me ka huli ʻana, ka wili ʻana, ka wili ʻana, ka ʻoki ʻana, a me nā mea ʻē aʻe, akā hiki iā lākou ke hoʻokō i ka hana ʻana o nā ʻāpana graphite me nā ʻano maʻalahi a me ka pololei haʻahaʻa. Me ka hoʻomohala wikiwiki ʻana a me ka hoʻohana ʻana i nā kikowaena mīkini wikiwiki graphite, nā mea ʻokiʻoki, a me nā ʻenehana kākoʻo e pili ana, ua pani mālie ʻia kēia mau ʻano hana mīkini kuʻuna e nā ʻenehana mīkini wikiwiki. Ua hōʻike ʻia ka hana: ma muli o nā ʻano paʻakikī a palupalu o ka graphite, ʻoi aku ka koʻikoʻi o ka ʻaʻahu o ka mea hana i ka wā o ka hana ʻana, no laila, ua ʻōlelo ʻia e hoʻohana i nā mea hana carbide a i ʻole daimana.
Nā ana hana ʻoki
Ma muli o ke ʻano kūikawā o ka graphite, i mea e hoʻokō ai i ka hana ʻana o nā ʻāpana graphite kiʻekiʻe, pono e hana ʻia nā ana hana e like me ia. I ka wā e ʻokiʻoki ai i ka mea graphite, hiki i ka mea hana ke hānai pololei i ka workpiece, me ka hoʻohana ʻana i nā palena ʻoki nui; i mea e pale aku ai i ka haki ʻana i ka wā e hoʻopau ai, hoʻohana pinepine ʻia nā mea hana me ke kūpaʻa maikaʻi e hōʻemi i ka nui o ka ʻoki ʻana o ka mea hana, a e hōʻoia i ka emi ʻana o ka pitch o ka mea hana ʻoki ma mua o 1/2 o ke anawaena o ka mea hana, a e hana i nā ana hana e like me ka hana deceleration i ka wā e hana ai i nā wēlau ʻelua [4].
Pono nō hoʻi e hoʻonohonoho pono i ke ala ʻoki i ka wā e ʻoki ai. I ka wā e hana ai i ke koʻokoʻo o loko, pono e hoʻohana ʻia ke koʻokoʻo a puni e like me ka hiki ke ʻoki i ka ʻāpana ikaika o ka ʻāpana ʻoki i ʻoi aku ka mānoanoa a me ka ikaika, a e pale i ka haki ʻana o ka mea hana [5]. I ka wā e hana ai i nā mokulele a i ʻole nā auwai, e koho i ka hānai diagonal a i ʻole spiral e like me ka hiki; e pale i nā mokupuni ma ka ʻili hana o ka ʻāpana, a e pale i ka ʻoki ʻana i ka mea hana ma ka ʻili hana.
Eia kekahi, ʻo ke ʻano ʻoki he mea nui hoʻi e hoʻopilikia ai i ka ʻoki ʻana i ka graphite. ʻOi aku ka haʻalulu o ka ʻoki ʻana i ka wā o ka wili ʻana i lalo ma mua o ka wili ʻana i luna. Hoʻemi ʻia ka mānoanoa o ka ʻoki ʻana o ka mea hana i ka wā o ka wili ʻana i lalo mai ka palena kiʻekiʻe a i ka ʻole, a ʻaʻohe hanana lele ma hope o ka ʻoki ʻana o ka mea hana i loko o ka ʻāpana hana. No laila, koho pinepine ʻia ka wili ʻana i lalo no ka hana ʻana i ka graphite.
I ka wā e hana ai i nā ʻāpana hana graphite me nā ʻano paʻakikī, me ka hoʻonui ʻana i ka ʻenehana hana e pili ana i nā noʻonoʻo i luna, pono e hana ʻia kekahi mau hana kūikawā e like me nā kūlana kikoʻī e hoʻokō ai i nā hopena ʻoki maikaʻi loa.
