Hoʻohana nui ʻia ʻo Edm no ka mīkini mīkini a me nā ʻāpana me nā ʻano paʻakikī o nā lua a me nā lua; Ka hana ʻana i nā mea conductive like ʻole, e like me ka paʻa paʻa a me ke kila paʻakikī; Ka hana ʻana i nā puka hohonu a maikaʻi, nā puka ʻano kūikawā, nā awāwa hohonu, nā ʻāpana haiki a me ka ʻoki ʻana i nā ʻāpana lahilahi, etc.; ʻO ka mīkini ʻana i nā mea hana hana like ʻole, nā mamana a me nā ana apo kaula, etc.

ʻO ke kumu hana

I ka wā o ka EDM, ua hoʻopiliʻia ka mea hana uila a me ka mea hana i nā pouʻelua o ka mana pulse a hoʻokomoʻia i loko o ka wai hana, aiʻole ka wai hana i hoʻokomoʻia i loko o ka puka hoʻokuʻu. ʻōnaehana hoʻomalu aunoa āpau. Ke hiki aku ka āwāwa ma waena o nā electrodes ʻelua i kahi mamao, ʻo ka uila impulse i kau ʻia ma nā electrodes ʻelua e wāwahi i ka wai hana a hoʻopuka i ka hoʻokuʻu ʻana.

I ka micro channel o ka hoʻokuʻu ʻana, nui ka nui o ka ikehu wela i ka manawa koke, hiki ke kiʻekiʻe ke kiʻekiʻe e like me 10000 ℃ a he loli ʻoi hoʻi ke kaomi, no laila e hoʻololi koke nā mea metala kūloko ma ka papa hana o kēia wahi. hehee a vaporize, a pahū i loko o ka hana wai, koke condense, hana paʻa metala particles, a lawe aku e ka hana liquid.At keia manawa ma ka ili o ka workpiece e waiho i kahi lua liilii. hōʻailona, ​​ua oki pōkole ka hoʻokuʻu ʻana, ka wai hana ma waena o nā electrodes ʻelua e hoʻihoʻi i ke kūlana insulation.

ʻO ka puʻupuʻu puʻupuʻu aʻe e haki i lalo ma kahi ʻē aʻe kahi e pili kokoke ai nā electrodes i kekahi i kekahi, e hana ana i ka hoʻokuʻu ʻana a me ka hana hou ʻana i ke kaʻina. i nā tausani o ka hoʻokuʻu ʻana o ka pulse i kēlā me kēia kekona, me kahi huahana.

Ma lalo o ke ʻano o ka mālama ʻana i ka lua hoʻokuʻu mau ma waena o ka electrode mea hana a me ka mea hana, ua ʻino ʻia ka metala o ka mea hana i ka wā e hānai mau ʻia ai ka electrode mea hana i loko o ka mea hana, a ma hope o ke ʻano e pili ana i ke ʻano o ka mea hana electrode e mīkini ʻia. No laila, e like me ka lōʻihi o ke ʻano o ka electrode mea hana a me ke ʻano o ka neʻe ʻana ma waena o ka electrode mea hana a me ka mea hana, hiki ke hana ʻia nā ʻano paʻakikī paʻakikī. corrosion-kūpaʻa mea me ka maikaʻi conductivity, kiʻekiʻe hehee ai wahi a me ka oluolu hana, e like me ke keleawe, graphite, keleawe-tungsten alloy a me molybdenum.I ke kaʻina hana o ka machining, ka mea hana electrode i poho, akā, emi ma mua o ka nui o ka corrosion o ka. metala mea hana, a kokoke i ka poho ole.

Ma keʻano he mea hoʻokuʻu, hana pū ka wai hana i ka hoʻomaha a me ka weheʻana i ka chip i ka wā o ka hana. he ʻano o ka hoʻokuʻu ʻana iā ia iho, ʻo kona mau hiʻohiʻona e like me kēia: ʻo nā electrodes ʻelua o ka hoʻokuʻu ʻia ʻana he volta kiʻekiʻe ma mua o ka hoʻokuʻu ʻana, ke hoʻokokoke nā electrodes ʻelua, ʻo ka medium wawahi iho, a laila e hoʻokuʻu ʻia ka uila. A me ke kaʻina hana wāwahi, e emi nui ke kū'ē ma waena o nā electrodes ʻelua, a me ka emi ʻana o ka uila ma waena o nā electrodes. (ʻo ka maʻamau 10-7-10-3s) no ka mālama ʻana i nā hiʻohiʻona "maʻa anu" o ka hoʻokuʻu ʻana o ke ahi (ʻo ia hoʻi, ʻaʻole hiki i ka ikehu wela o ka hoʻololi ʻana i ka ikehu channel i ka hohonu o ka electrode. i ka manawa), no laila e hoʻohana ʻia ka ikehu kanal i kahi palena liʻiliʻi. Hiki i ka hopena o ka ikehu kanal ke hoʻoheheʻe ʻia ka electrode i ka wahi. ʻO ka hoʻoheheʻe ʻana i ka uila uila. ʻO Edm kahi hoʻoheheʻe ʻana i loko o kahi ʻano wai i loko o kahi ākea haʻahaʻa haʻahaʻa. E like me ke ʻano o ka mea hana electrode a me nā hiʻohiʻona o ka neʻe pili ma waena o ka mea hana electrode a me ka mea hana, hiki ke edM māhele ʻia i ʻelima mau ʻano. Wire-cut edM oki o conductive mea hoʻohana axially neʻe uea like me ka mea paahana electrode a me ka workpiece neʻe ma ka makemake shape a me ka nui; machining thread ring gage, thread plug gage [1], gear etc. ʻO ka hoʻoponopono puka liʻiliʻi, ka hoʻopili ʻana i ka ʻili, ka hoʻoikaika ʻana i ka ʻili a me nā ʻano hana ʻē aʻe. Hiki iā Edm ke hana. nā mea a me nā ʻano paʻakikī i paʻakikī ke ʻoki ʻia e nā ʻano mīkini maʻamau. ka hana ʻana, maʻalahi e hoʻokō i ka automation; Ma hope o ka hana ʻana, hana ka ʻili i kahi papa metamorphosis, i loko o kekahi mau noi e pono e wehe hou ʻia; wai hana.
