EDMhe hana machining e hoʻohana nui ana i kahi electrode discharge (EDM electrode) me kahi geometry kikoʻī e puhi i ka geometry o ka electrode ma kahi ʻāpana metala (conductive).ʻO ke kaʻina hana EDMhoʻohana mau ʻia i ka hana ʻana i ka blanking a me ka hoʻolei ʻana i make.
ʻO ke ʻano o ka hoʻoili ʻana i ka dimensional o nā mea me ka hoʻohana ʻana i ka hanana corrosion i hana ʻia e ka hoʻokuʻu ʻana i kapa ʻia ʻo EDM.ʻO ka EDM kahi hoʻoheheʻe ʻana i loko o kahi ʻano wai ma kahi ākea haʻahaʻa haʻahaʻa.
ʻO ka EDM kahiʻano o ka hoʻokuʻuʻana iā ia iho, aʻo kona mau hiʻohiʻona e like me kēia: ʻO nā electrodes ʻelua o ka hoʻokuʻu ʻana i ka spark he kiʻekiʻe ka uila ma mua o ka hoʻokuʻu ʻana.Ke kokoke nā electrodes ʻelua i kekahi i kekahi, ma hope o ka haki ʻana o ka waena waena o lākou, hiki koke ka hoʻokuʻu ʻana.Me ka haʻihaʻi kaʻina hana, ke kū'ē ma waena o nā electrodes 'elua e emi loa, a me ka voltage ma waena o nā electrodes 'elua ho'ēmi iki.Pono e ho'opau 'ia ke ala ahi i ka manawa ma hope o ka mālama 'ana i kahi manawa pōkole (ma'a mau 10-7-10-3s), no ka mālama 'ana i nā 'ano o ka "pole anu" o ka ho'oku'u 'ana ('o ia ho'i, ka ikehu wela o ka ho'ololi 'ana i ka ikehu channel. ʻAʻole hiki ke hoʻouna ʻia i ka hohonu o ka electrode), no laila e hana ka ikehu Channel ma kahi ʻano liʻiliʻi loa.Hiki i ka hopena o ka ikehu kanal ke hoʻopōʻino ʻia ka electrode.
Nā hiʻohiʻona:
1.EDM no ka machining non-contact
ʻAʻohe pilina pololei ma waena o ka mea uila a me ka mea hana, akā aia kahi ʻāpana hoʻokuʻu.ʻO kēia āpau ma waena o 0.05 ~ 0.3mm, a i kekahi manawa hiki i ka 0.5mm a i ʻole ka nui.Hoʻopihaʻia ka'āpana me ka wai hana, a me ka hoʻokuʻuʻana o Pulse kiʻekiʻe, hoʻokuʻu i ka corrosion ma ka mea hana.
2. Hiki ke "hoʻopiʻi i ka rigidity me ka palupalu"
Ma muli o ka hoʻohana ponoʻana o EDM i ka ikehu uila a me ka ikehu wela no ka weheʻana i nā mea metala, he mea liʻiliʻi ia me ka ikaika a me ka paʻakikī o ka mea hana mea hana, no laila hiki ke hoʻohanaʻia nā electrodes mea hana maʻemaʻe e hana i nā mea hana paʻakikī e loaʻa ai ka "softness overcomes rigidity".
3. Hiki ke hana i nā mea metala paʻakikī a me nā mea conductive
Ma muli o ka lawe ʻia ʻana o nā mea i ka wā o ka hoʻoili ʻana e hoʻokō ʻia e nā hopena uila a me ka wela o ka hoʻokuʻu ʻana, ʻo ka machinability o nā mea e hilinaʻi nui ʻia i ka conductivity uila a me nā waiwai wela o nā mea, e like me ka helu heheʻe, ka paila paila, ka mana wela kikoʻī, conductivity thermal, resistivity. , a me nā mea'ē aʻe,ʻoiaiʻaneʻaneʻAʻohe mea e pili ana i kona mau mea mechanical (paʻakikī, ikaika, a me nā mea'ē aʻe).Ma kēia ala, hiki iā ia ke uhaki i nā palena o nā mea ʻoki kuʻuna ma luna o nā mea hana, a hiki ke hoʻomaopopo i ka hana ʻana o nā mea hana paʻakikī a paʻakikī me nā mea paʻakikī, a hiki ke hana ʻia nā mea superhard e like me nā lālani daimana polycrystalline a me cubic boron nitride.
4. Hiki ke hoʻohana ʻia nā ʻili o ke ʻano paʻakikī
No ka mea hiki ke kope wale ʻia ke ʻano o ka electrode mea hana i ka mea hana, kūpono loa ia no ka hana ʻana i nā mea hana me nā hiʻohiʻona ʻili paʻakikī, e like me ka hoʻoheheʻe ʻana i ka lua.ʻO ka mea nui, ʻo ka hoʻohana ʻana i ka ʻenehana mana helu he mea maoli ia e hoʻohana i nā electrodes maʻalahi e hoʻoponopono i nā ʻāpana me nā ʻano paʻakikī.
5. Hiki ke hanaʻia nā'āpana me nā koi kūikawā
Hiki iā ia ke hana i nā ʻāpana me nā koi kūikawā e like me ka lahilahi-walled, elastic, low-rigidity, nā puka liʻiliʻi, nā puka kūikawā, nā lua hohonu, a me nā mea ʻē aʻe, a hiki ke hana pū i nā hua liʻiliʻi ma ka mold.No ka mea ʻaʻole pili pono ka electrode mea hana a me ka mea hana i ka wā o ka mīkini, ʻaʻohe ikaika ʻoki no ka mīkini, no laila ua kūpono ia no ka hana ʻana i nā mea hana haʻahaʻa rigidity a me ka micromachining.
ʻO EDM kekahi ʻano kaʻina hana mīkini, hiki iā mākou ke kōkua iā ʻoe e hoʻoponopono i kāu pilikia maʻamau.
Inā he nīnau kāu a makemake paha e makemake i kekahi lawelawe maʻamau e pili ana i ka CNC Machining, e ʻoluʻolu e leka uila mai iā mākou.
