I ka hana ʻana i nā ʻōmole a me nā make, ʻelua o nā ʻenehana mīkini i hoʻohana nui ʻia ʻo ia ka Electrical Discharge Machining (EDM) a me CNC Milling. He kuleana koʻikoʻi nā kaʻina hana ʻelua i ka hana ʻana i ka ʻōmole, akā lawelawe lākou i nā kumu like ʻole a hāʻawi i nā pono kūikawā.

Ma kēia ʻatikala, hoʻohālikelike mākouʻO ka wili ʻana o EDM a me CNCno ka hana ʻana i ka ʻōmole a wehewehe i ka wā e hoʻohana ʻia ai kēlā me kēia ʻenehana.

He aha ka wili CNC?

ʻO ka wili CNC kahi hana mīkini subtractive e wehe ai i nā mea me ka hoʻohana ʻana i nā mea ʻokiʻoki wili.

Hoʻohana nui ʻia nā kikowaena mīkini CNC hou no:

• Ka mīkini kumu hoʻoheheʻe
• Ka mīkini ʻana i nā lua ʻinoʻino
• ʻO ka mīkini contour
• Hana ʻana o ka electrode
• Hana ʻāpana kikoʻī

ʻO nā pōmaikaʻi o ka wili CNC:

• Ka wikiwiki o ka wehe ʻana i nā mea
• Ka wikiwiki o ka mīkini
• Kumukūʻai hana haʻahaʻa
• Ka huahana maikaʻi loa no ka wehe ʻana i nā mea nui

Eia nō naʻe, ua kaupalena ʻia nā mea hana CNC e ko lākou geometry kino a ʻaʻole hiki ke hana maʻalahi i nā kihi kūloko ʻoi a i ʻole nā ​​​​lua hohonu loa.

He aha ka EDM?

Mīkini Hoʻokuʻu UilaHoʻoneʻe ʻo EDM i nā mea ma o nā hunaahi uila i kāohi ʻia ma waena o kahi electrode a me ka workpiece.

ʻAʻole e like me ka wili ʻana, ʻaʻole hoʻohana ʻo EDM i ka ikaika ʻoki mechanical.

Hoʻohana pinepine ʻia ʻo EDM no:

• Ka mīkini ʻana i nā lua hohonu
• Ka hana ʻana i ke kihi ʻoi
• ʻO ka mīkini kila paʻakikī
• Nā kikoʻī hoʻoheheʻe paʻakikī
• Nā hana hoʻopau maikaʻi

Ma muli o ka ʻole o ka hoʻopā pololei ʻana me ka mea hana, hiki i ka EDM ke wili i nā mea me ka nānā ʻole i ka paʻakikī.

ʻO ka wili ʻana o EDM vs CNC: Nā ʻokoʻa koʻikoʻi

1. Kumumanaʻo Mīkini

2. Ka hiki ke hana i ke kila paʻakikī

CNC Milling

Hoʻonui nui ʻia ke ʻano o ka hana ʻana i nā mea hana ke hana ʻia nā mea paʻakikī ma luna o HRC 50–55.

EDM

ʻAʻole nui ka hopena o ka paʻakikī o nā mea i ka hiki ke hana mīkini.

No ke kila hoʻoheheʻe paʻakikī, hāʻawi ʻo EDM i kahi pono nui.

3. Nā Kihi Kūloko a me ke ʻAno Honua Paʻakikī

ʻO kekahi o nā palena nui o ka wili CNC ʻo ke anawaena o ka mea hana.

ʻOiai nā wili liʻiliʻi e waiho i nā radii kihi.

ʻo kahi laʻana:

• ʻAʻole hiki i ka wili CNC ke hana i nā kihi kūloko ʻoi loa.
• Hiki i ka EDM ke hana hou pololei i ke ʻano o ka electrode, me nā kihi ʻoi a me nā kikoʻī paʻakikī.

4. Ka wikiwiki o ka mīkini

No ke kāwili ʻana i nā mea he nui:

ʻOi aku ka wikiwiki o ka wili ʻana o CNC.

ʻO ka wehe ʻana i kahi lua nui me ka EDM he mea kūpono ʻole ia a he mea pipiʻi hoʻi.

Hoʻohana ka hapa nui o nā mea hana hoʻoheheʻe i ka wili CNC mua a ma hope ʻo EDM.

5. Hoʻopau ʻili

Hiki i ka ʻenehana EDM hou ke hana i nā ʻano hoʻopau ʻili maikaʻi loa i kūpono no nā noi hoʻoheheʻe he nui.

ʻO nā pono e komo pū ana:

• Hoʻemi ʻia ka manawa wili
• ʻOi aku ka maikaʻi o ke kūlike o ka lua
• Ka mana ʻano maikaʻi

Hiki i ka wili wikiwiki ke hoʻokō i ka maikaʻi o ka ʻili, akā hāʻawi pinepine ka EDM i nā hopena maikaʻi aʻe ma nā wahi paʻakikī ke hiki aku.

6. Ka ʻaʻahu ʻana i nā mea hana

ʻO ke kumukūʻai maoli e pili ana i ka noi.

---

7. Mīkini Hana Lua Hohonu

He mau pilikia nā lua hohonu a haiki no nā mea hana wili.

ʻO nā pilikia e komo pū ana me:

• Ka hoʻohuli ʻana o ka mea hana
• Haʻalulu
• Ka haki ʻana o ka mea hana

ʻOi aku ka maikaʻi o EDM ma ia mau kūlana.

Papa Hoʻohālikelike

I ka manawa hea ʻoe e koho ai i ka CNC Milling?

He kūpono ka wili CNC i ka wā:

• Pono e wehe koke ʻia nā mea he nui
• Ke hana nei i nā kumu hoʻoheheʻe
• Ke hana ʻana i nā lua hāmama
• Hana ʻana i nā electrodes
• Ke hoʻokō nei i ka hana kiʻekiʻe

No nā hana mīkini ʻana maʻamau, ʻo ka wili CNC ka hopena maʻamau ʻoi aku ka waiwai.

---

Āhea ʻoe e koho ai iā EDM?

ʻOi aku ka maikaʻi o ka EDM i ka wā:

• Ke hana ʻana i ke kila kila paʻakikī
• Ke hana ʻana i nā lua hohonu
• Ke hana nei i nā kihi kūloko ʻoi
• Nā kikoʻī hoʻoheheʻe paʻakikī
• Ka hoʻokō ʻana i ka hoʻopau ʻili maikaʻi loa

No ka hoʻopau ʻana i nā hana a me nā hiʻohiʻona hoʻoheheʻe paʻakikī, lilo pinepine ʻo EDM i mea pono ʻole.

---

No ke aha e hoʻohana ai ka hapa nui o nā mea hana mold i nā mea ʻelua

ʻO ka ʻoiaʻiʻo, ʻaʻole hoʻokūkū ʻo EDM a me CNC milling—he mau ʻenehana hoʻokō like lāua.

ʻO ke ʻano o ka hana hana hoʻoheheʻe maʻamau penei:

Hāʻawi kēia hui pū ʻana i ke kaulike maikaʻi loa ma waena o ka wikiwiki, ka pololei, a me ke kumukūʻai.

---

ʻO wai ka mea maikaʻi no ka hana ʻana i ka mold?

Aia ka pane ma ka noi.

Inā ʻo ka pahuhopu ka wehe wikiwiki ʻana i nā mea a me ka hana kiʻekiʻe, ʻo ka wili CNC ka hopena makemake ʻia.

Inā ʻo ka pahuhopu ka mīkini ʻana i ke kila paʻakikī, nā lua hohonu, nā geometries paʻakikī, a i ʻole nā ​​​​kikoʻī hoʻoheheʻe pololei kiʻekiʻe, ʻo EDM pinepine ke koho ʻoi aku ka maikaʻi.

No ka hapa nui o nā mea hana hoʻoheheʻe ʻoihana, ʻo ke ala maikaʻi loa ʻaʻole ia ka wili EDM a i ʻole CNC—ʻo ia ka hoʻohana ʻana i nā ʻenehana ʻelua e hoʻonui i ka pono a me ka maikaʻi.

Hopena

He kuleana koʻikoʻi ko ka wili ʻana o EDM a me CNC i ka hana ʻana i nā mold o kēia au.

Hāʻawi ka wili CNC i ka wikiwiki a me ka pono no ka mīkini ʻana i nā ʻōpala, ʻoiai ʻo EDM e hāʻawi i ka pololei a me ka maʻalahi e pono ai no nā hiʻohiʻona hoʻoheheʻe paʻakikī.

ʻO ka hoʻomaopopo ʻana i nā ikaika o kēlā me kēia kaʻina hana e hiki ai i nā mea hana ke koho i ka ʻenehana kūpono no kēlā me kēia pae o ka hana ʻana i ka mold, e hopena ana i ka maikaʻi ʻoi aku ka maikaʻi, nā manawa alakaʻi pōkole, a me nā kumukūʻai hana haʻahaʻa holoʻokoʻa.
