1. E pili anaMea ʻoki wili graphite
Ke hoʻohālikelike ʻia me nā electrodes keleawe, loaʻa i nā electrodes graphite nā mea maikaʻi e like me ka hoʻohana ʻana i ka electrode haʻahaʻa, ka wikiwiki wikiwiki ʻana, ka hana hana mechanical maikaʻi, ka hoʻoponopono kiʻekiʻe kiʻekiʻe, ka deformation thermal liʻiliʻi, ke kaumaha māmā, ka maʻalahi o ka mālama ʻana i ka ʻili, ke kūpaʻa wela kiʻekiʻe, ke kiʻekiʻe o ka hana ʻana, a me ka electrode adhesion. .
ʻOiaiʻo ka graphite he mea maʻalahi loa eʻokiʻoki,ʻo ka mea graphite i hoʻohanaʻia ma keʻano he electrode EDM pono e lawa ka ikaika e pale ai i ka pōʻino i ka wā o ka hana a me ka hana EDM.I ka manawa like, ʻo ke ʻano electrode (nā ʻāpana lahilahi, nā kihi poʻe liʻiliʻi, nā hoʻololi ʻoi aku, a me nā mea ʻē aʻe) e kau i nā koi kiʻekiʻe ma ka nui o ka palaoa a me ka ikaika o ka electrode graphite, e alakaʻi ana i ka mea hana graphite i ka fragmentation a me ka mea hana. ʻaʻahu i ka wā e hana ai.
2. Mea hana wili graphitemea waiwai
ʻO ka mea paahana ke kumu kumu e hoʻoholo ai i ka hana ʻoki ʻana o ka mea hana, he hopena koʻikoʻi i ka hana ʻana i ka mīkini, ka maikaʻi, ke kumukūʻai, a me ka lōʻihi o ka mea hana.ʻOi aku ka paʻakikī o ka mea paahana, ʻoi aku ka maikaʻi o kona pale ʻana, ʻoi aku ka kiʻekiʻe o kona paʻakikī, ʻoi aku ka haʻahaʻa o kona ʻano paʻakikī, a ʻoi aku ka palupalu o ka mea.
ʻO ka paʻakikī a me ka paʻakikī he mea kū'ē a he pilikia nui e pono e hoʻoponopono i nā mea hana.
No nā mea hana ʻoki kiʻi kiʻi, hiki ke koho i nā mea hoʻonaninani TIAIN maʻamau me ka ʻoi aku ka ʻoi aku o ka paʻakikī, ʻo ia hoʻi, ka poʻe me nā ʻano kobalt kiʻekiʻe iki;No nā mea hana ʻoki graphite i uhi ʻia i ke daimana, hiki ke koho pono ʻia nā mea me ka ʻoi aku ka ʻoi aku o ka ʻoi aku o ka paʻakikī, ʻo ia hoʻi me ka ʻike kobalt haʻahaʻa.
3. Komi geometric mea hana
Nā mea hana ʻoki graphite kūikawāʻO ke koho ʻana i ke kihi geometric kūpono e kōkua i ka hōʻemi ʻana i ka haʻalulu o ka mea hana, a ʻoi aku ka liʻiliʻi o nā mea hana graphite i ka haki.
huina mua
Ke hoʻohana nei i ke kihi rake maikaʻi ʻole e hana i ka graphite, maikaʻi ka ikaika o ka ʻaoʻao o ka mea hana, a maikaʻi ka hopena o ka hopena a me ka hana friction.E like me ka emi ʻana o ke kumu kūʻai o ka angle rake maikaʻi ʻole, ʻaʻole loli nui ka ʻāpana o ka ʻili o ka mea hana hope, akā hōʻike ka holoʻokoʻa i kahi ʻano emi.I ka hoʻohana ʻana i ka kihi rake maikaʻi e hana ai, i ka piʻi ʻana o ka angle rake, nāwaliwali ka ikaika o ka ʻaoʻao o ka mea hana, a ma kahi o ka hoʻohana ʻana i ka ʻili o ka mea hana hope.I ka hana ʻana me kahi kihi rake maikaʻi ʻole, ʻoi aku ka kiʻekiʻe o ka ʻoki ʻana, kahi e hoʻonui ai i ka ʻoki ʻana.I ka hana ʻana me kahi kihi rake maikaʻi nui, ʻoi aku ka paʻakikī o ka mea hana, a ʻoi aku ka kiʻekiʻe o ka ʻoki ʻana.
kihi hoʻomaha
Inā piʻi ke kihi hope, e emi ana ka ikaika o ka ʻaoʻao o ka hāmeʻa a e piʻi mālie ka ʻāpana o ka ʻili o ka mea hana hope.Ke ʻoi aku ka nui o ke kihi hope o ka hāmeʻa, piʻi ka haʻalulu ʻoki.
kihi helix
Ke liʻiliʻi ka ʻoki helix, ʻoi aku ka lōʻihi o ka ʻoki ʻoki i ka manawa like i ka mea hana graphite ma nā kihi ʻoki āpau, ʻoi aku ka nui o ka ʻoki ʻana, a ʻoi aku ka ikaika o ka ʻoki ʻana e ka mea hana, e hopena i ka ʻoi aku o ka mea hana. , ka ikaika wili, a me ka ʻoki ʻana i ka haʻalulu.I ka nui o ka huina helix, e hele nui ana ke kuhikuhi o ka wili palaoa mai ka ili o ka mea hana.ʻO ka hopena o ka ʻoki ʻana ma muli o ka ʻokiʻoki ʻana o nā mea graphite e hoʻonui ai i ka ʻaʻahu, a ʻo ka hopena o ka ikaika wili a me ka ʻoki ʻana i ka vibration ʻo ia ka hui ʻana o ke kihi mua, ke kihi hope, a me ke kihi helix.No laila, pono e uku nui i ke koho ʻana.
3.wili hope no ka graphite ka uhi ʻana
ʻO nā mea hana ʻoki ʻoki ʻoki PCD loaʻa nā pōmaikaʻi e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi ʻana i ka lole, a me ka coefficient friction haʻahaʻa.
I kēia manawa, ʻo ka uhi daimana ke koho maikaʻi loa no nā mea hana graphite machining a hiki ke hōʻike maikaʻi i ka hana maikaʻi o nā mea hana graphite.ʻO ka maikaʻi o ka mea hana carbide i uhi ʻia i ke daimana ʻo ia ka hui pū ʻana i ka paʻakikī o ke daimana maoli me ka ikaika a me ka paʻakikī Fracture o ka carbide.
He ʻokoʻa loa ka huina geometric o nā mea hana i uhi ʻia i ke daimana mai ko nā uhi maʻamau.No laila, i ka hoʻolālā ʻana i nā mea hana i uhi ʻia i ke daimana, ma muli o ke ʻano kūikawā o ka hoʻoili ʻana i ka graphite, hiki ke hoʻonui ʻia ke kihi geometric, a hiki ke hoʻonui ʻia ka puʻupuʻu paʻa puʻupuʻu, me ka ʻole e hōʻemi i ka pale ʻana o ka ʻaoʻao o ka mea hana.No nā pale lole TIAIN maʻamau, ʻoiai ʻoi aku ka maikaʻi o ko lākou pale ʻana i ka ʻaʻahu i ka hoʻohālikelike ʻia me nā mea hana i uhi ʻole ʻia, ke hoʻohālikelike ʻia me nā uhi daimana, pono e hoʻemi ʻia ke kihi geometric i ka wā e hoʻomaʻamaʻa ai i ka graphite e hoʻonui i kona pale ʻana.
4. ʻO ka passivation o ka pahi
ʻO ka ʻenehana passivation o ka ʻoki ʻana he mea koʻikoʻi loa ia i ʻike ʻole ʻia.Aia kona koʻikoʻi i ka ʻoiaʻiʻo e hiki i ka mea hana passivated ke hoʻomaikaʻi maikaʻi i ka ikaika lihi, ke ola mea hana, a me ke kūpaʻa o ke kaʻina ʻoki.ʻIke mākou ʻo ka ʻoki ʻana i nā "niho" o nā mea mīkini, a ʻo nā kumu nui e pili ana i ka hana ʻoki a me ke ola mea hana.Ma waho aʻe o nā mea hana, nā ʻāpana geometric hāmeʻa, ka hoʻolālā mea hana, ka ʻoki ʻana i ka parameter optimization, a me nā mea ʻē aʻe, ma o ka nui o nā hana passivation lihi o ka mea hana, ua ʻike mākou ʻo ka loaʻa ʻana o kahi ʻano lihi maikaʻi a me ka maikaʻi passivation lihi he mea pono no ka mea hana. i hiki ke hana i ka hana oki maikai.No laila, ʻo ke ʻano o ka ʻoki ʻoki he mea hiki ʻole ke mālama ʻia
5. ʻO ke ʻano ʻoki
ʻO ke kohoʻana i nā kūlanaʻokiʻoki he hopena koʻikoʻi i ke ola mea hana.
ʻOi aku ka liʻiliʻi o ka ʻoki ʻana o ka wili i mua ma mua o ka wili hoʻohuli.I ka wā e wili ai i mua, e emi ana ka mānoanoa oki o ka mea hana mai ka palena a i ʻole.Ma hope o ka ʻoki ʻana o ka mea hana i loko o ka mea hana, ʻaʻohe mea e hoʻoulu ʻia e ka hiki ʻole ke ʻoki i nā ʻāpana.ʻO ka'ōnaehana kaʻina hana he rigidity maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa;I ka wā wili hoʻohuli, piʻi ka mānoanoa ʻoki ʻana o ka mea hana mai ka ʻole a hiki i ka nui.I ka pae mua o ka ʻoki ʻana, ma muli o ka mānoanoa ʻokiʻoki lahilahi, e huki ʻia kahi ala ma ka ʻili o ka mea hana.I kēia manawa, inā ʻike ka ʻoki ʻoki i nā wahi paʻakikī i loko o nā mea graphite a i ʻole nā mea ʻāpana chip ma luna o ka ʻili o ka mea hana, e hoʻoulu ai ka mea hana i ka haʻalulu a i ʻole ka haʻalulu, e hopena i ka haʻalulu nui i ka wā o ka wili ʻana.
ʻO ka puhi ʻana (a i ʻole ka hoʻoheheʻe ʻana) a me ka hoʻokomo ʻana i ka mīkini hoʻoheheʻe uila
ʻO ka hoʻomaʻemaʻe ʻana i ka lepo graphite ma ka ʻili o ka mea hana he mea maikaʻi ia no ka hoʻohaʻahaʻa ʻana i ka lole hana lua, hoʻolōʻihi i ke ola lawelawe mea hana, a me ka hoʻohaʻahaʻa ʻana i ka hopena o ka lepo graphite ma nā wili a me nā alakaʻi.
