Hoʻohana nui ʻia ʻo Edm no ka mīkini mīkini a me nā ʻāpana me nā ʻano paʻakikī o nā lua a me nā lua; ʻO ka hana ʻana i nā mea conductive like, e like me ke kinikini paʻa a me ke kila paʻakikī; Ka hana ʻana i nā lua hohonu a maikaʻi, nā puka ʻano kūikawā, nā lua hohonu, nā hono liʻiliʻi a me ka ʻoki ʻana i nā ʻoki lahilahi, a pēlā aku. ʻO ka mīkini ʻana i nā pono hana, nā anakuhi a me nā ana o nā pae o nā pae, etc.

Ke kumu hana

I ka manawa o EDM, pili ka electrode mea hana a me ka workpiece i nā kia ʻelua o ka lako mana lāʻau ikiʻai a hoʻokomo ʻia i loko o ka wai hana, a i ʻole ua hoʻopiʻi ʻia ka wai hana i loko o ka hakahaka hoʻokuʻu. Kohi ʻia ka electrode mea hana e hānai i ka mea hana ma o ka ʻōnaehana hoʻoholo miki. Ke hiki i ka hakahaka ma waena o nā electrodes ʻelua i kahi mamao, ka uila impulse i noi ʻia ma nā electrodes ʻelua e wāwahi i ka wai hana a hana i ka hoʻokuʻu spark.

I ke kahawai micro o ka hoʻokuʻu ʻana, hoʻopili nui ʻia ka nui o ka ikehu wela, hiki ke kiʻekiʻe o ka mahana me 10000 has a he loli nui hoʻi ka kaomi, no laila nā mea metala e pili pono ana i ka papa hana o kēia kiko i kēia manawa. e hoʻoheheʻe a mahu, a pahū i loko o ka wai e hana ana, e hoʻoheʻe koke, e hana i nā mea paʻa a paʻa, a lawe ʻia e ka wai hana. I kēia manawa ma ka ʻili o ka mea hana e waiho i kahi kaha lua, ua kū iki ka hoʻokuʻu. e hana ana i ka wai ma waena o nā uila uila ʻelua e hoʻihoʻi i ke kūlana hoʻohaunaele.

A laila haki ka uila pulse aʻe ma kahi kiko kahi kahi kokoke o nā electrodes i kekahi i kekahi, e hana ana i kahi hoʻokuʻu ahi a hana hou i ke kaʻina. Pēlā, ʻoiai ka liʻiliʻi o ka nui o nā metala i hoʻoheheʻe ʻia no ka hoʻokuʻu ʻana i ka lāʻau, ʻoi aku ka nui o nā mea hiki ke hemo ʻia ma muli o i nā tausani o ka pulse hoʻokuʻu i kēlā me kēia kekona, me kahi huahana.

Ma lalo o ke kūlana o ka mālama ʻana i ka hakahaka hoʻokuʻu mau ma waena o ka electrode mea hana a me ka workpiece, hana ʻia ka mea hao o ka mea hana i ka manawa e hānai mau ʻia ka mea hana uila i ka mea hana, a ʻo ka hopena ke ʻano e kūlike i ke ʻano o ka electrode mea hana i mīkini. No laila, ʻo ke ʻano o ka electrode mea hana a me ke ʻano o ka neʻe ma waena o ka electrode mea hana a me ka workpiece, hiki ke mīkini ʻia nā ʻano pilikino paʻakikī. Hana pinepine ʻia nā electrode coolers i nā mea kūpikū-kūpaʻa maikaʻi me ka conductivity maikaʻi, kahi hoʻoheheʻe kiʻekiʻe. a me ka maʻalahi hana, e like me keleawe, graphite, keleawe-tungsten oka a me molybdenum. I ke kaʻina hana o ka mīkini, he mea pohihihi ka mea pono uila, akā ʻoi aku ka liʻiliʻi o ka pala o nā mea hana, a kokoke paha i ka nalowale.

Ma ke ʻano he mea hoʻokuʻu, he mea nui ka wai hana i ka hoʻomaha ʻana a me ka lawe ʻana i ka chip i ka wā o ka hana. ʻO nā wai hana maʻamau ka waena me ka viscosity liʻiliʻi, ke kukui uila kiʻekiʻe a me ka hana paʻa, e like me ka petroline, ka wai deionized a me ka emulsion. kahi ʻano o ka hoʻokuʻu hoihoi ʻana iā ia iho, ʻo kona mau ʻano penei: ʻo nā electrode ʻelua o ka hoʻokuʻu kukuna i kahi uila kiʻekiʻe ma mua o ka hoʻokuʻu ʻana, ke hoʻokokoke nā electrodes ʻelua, ua haki ka medium, a laila puka ka hunaahi. Me ka hana breakdown, ke kūʻē ma waena o nā uila uila ʻelua e hoʻēmi nui, a me ka uila ma waena o nā uila uila e emi nui ana hoʻi. Pono e kinai ʻia ke kahawai hunaahi i ka manawa ma hope o ka mālama ʻia no kahi manawa pōkole (ʻo ka manawa maʻamau 10-7-10-3s) e mālama i ka " kia anu ”nā ʻano o ka hoʻokuʻu kukuna (ʻo ia hoʻi, ka ikehu wela o ka hoʻohuli ikehu o ke kahawai ʻaʻole hiki i ka hohonu o ka electrode i ka manawa), no laila e hoʻopili ʻia ka ikehu i kahi hopena palena iki. Hiki i ka hopena o ka ikehu o ke kahawai ke hana i ka uila i loko o ka ʻāina. ʻO ke kiʻina hana i hana ʻia i ka wā e hoʻohana ana i ka hoʻokuʻu sparks hana i ka dimensional machining i ka mea i kapa ʻia ka mīkini uila uila. waena ma waena o kahi pae uila lalo. E like me ke ʻano o ka electrode mea hana a me nā ʻano o ka neʻe ʻana ma waena o ka electrode mea hana a me ka workpiece, hiki ke hoʻokaʻawale ʻia ka edM i ʻelima mau ʻano. ʻO ka ʻoki edM ʻoki ʻana i nā mea conductive me ka hoʻohana ʻana i ka uea neʻe axial ma ke ʻano he electrode mea hana a neʻe i ka hana a me ka nui i makemake ʻia; Edm wili me ka hoʻohana ʻana i ka uea a i ʻole ke hoʻokumu ʻana i ka huila wili conductive ma ke ʻano he electrode mea hana no ka keyhole a i ʻole ka hana ʻana i ka wili; Hoʻohana ʻia no ka wili ʻana o ka wili mīkini , ka hoʻoikaika ʻana i ka ʻili a me nā ʻano hana like ʻole. Hiki i ka Edm ke hana i nā mea a me nā ʻano paʻakikī paʻakikī e ʻoki ʻia e ka mīkini maʻamau ʻAʻole hana ʻoki i ka wā o ka mīkini; ʻaʻole hana i ka burr a me ka ʻoki ʻana a me nā kīnā ʻē aʻe; ʻAʻole pono ka paʻakikī o nā mea uila uila ma mua o ka mea hana; hoʻohana pololei i ka hana uila uila, maʻalahi e hoʻokō i ka automation; Ma hope o ka hana ʻana, hana ka ʻili kahi papa metamorphosis, i kekahi o nā noi e pono e hemo hou aʻe; pilikia ia e hana me ka puhi uahi i hoʻokumu ʻia e ka hoʻomaʻemaʻe a me ka hana ʻana o ka wai hana.
