Pehea e ʻoki ai i ka metala?

ʻO ka hana mua o ka hana metala ʻo ka ʻoki ʻana, ʻo ia hoʻi ka ʻoki wale ʻana i nā mea maka a i ʻole ka hoʻokaʻawale ʻana iā lākou i loko o nā ʻano like ʻole e loaʻa ai nā hakahaka ʻōkeke. ʻO nā ʻano hana ʻoki metala maʻamau ka: ʻoki huila wili, ʻoki ʻike, ʻoki ahi, ʻoki plasma, ʻoki laser, a me ka ʻoki wai.
ʻOki huila wili
Ke hoʻohana nei kēia ʻano i ka huila wili kiʻekiʻe e ʻoki i ke kila. He ʻano ʻokiʻoki i hoʻohana nui ʻia. ʻO nā mea ʻoki huila wili he māmā, maʻalahi, maʻalahi, a maʻalahi hoʻi e hoʻohana, e hoʻohana nui ʻia lākou i nā ʻano hoʻonohonoho like ʻole, ʻoi aku ma nā kahua kūkulu a me nā papahana hoʻonaninani kūloko. Hoʻohana mua ʻia lākou no ka ʻoki ʻana i nā paipu huinahā liʻiliʻi, nā paipu poepoe, a me nā ʻano like ʻole.

ʻOki ʻike
ʻO ka ʻoki ʻana i ke ʻano o ka puʻunaue ʻana i nā mea hana a i ʻole nā ​​​​mea hana ma ke ʻoki ʻana i nā ʻāpana haiki me ka maka (saw disc). Hana ʻia ka ʻoki ʻana me ka mīkini ʻili metala. ʻO ka ʻoki ʻana i nā mea ʻo ia kekahi o nā koi kumu nui i ka hana metala, no laila saʻO nā mīkini w nā mea hana maʻamau i ka ʻoihana mīkini. I ka wā o ka ʻeli ʻana, pono e koho ʻia ka maka ʻili kūpono ma muli o ka paʻakikī o ka mea, a pono e hoʻoponopono ʻia ka wikiwiki o ka ʻoki ʻana.

ʻOki ʻana i ke ahi (Oxy-fuel oki)
ʻO ka ʻoki ʻana i ka lapalapa e pili ana i ka hoʻomehana ʻana i ka metala ma o ka hopena kemika ma waena o ka oxygen a me ke kila hoʻoheheʻe ʻia, hoʻoheheʻe ʻia a hoʻoheheʻe ʻia. ʻO ke kinoea hoʻomehana ka maʻamau acetylene a i ʻole kinoea maoli.
He kūpono wale nō ka ʻoki ʻana i ke ahi no nā pā kila kalapona a ʻaʻole pili i nā ʻano metala ʻē aʻe, e like me ke kila kuhili ʻole a i ʻole nā ​​ʻāpana keleawe/aluminika. ʻO kāna mau mea maikaʻi ʻo ia ke kumu kūʻai haʻahaʻa a me ka hiki ke ʻoki i nā mea a hiki i ʻelua mika ka mānoanoa. ʻO nā hemahema, ʻo ia ka wahi i hoʻopili ʻia i ka wela a me ka deformation thermal, me nā ʻāpana koʻikoʻi a me nā koena slag pinepine.

ʻOki Plasma
Hoʻohana ka ʻoki plasma i ka wela o ka arc plasma kiʻekiʻe e hoʻoheheʻe (a e hoʻoheheʻe) i ka metala ma ka ʻaoʻao ʻoki o ka mea hana, a wehe i ka metala hoʻoheheʻe me ka hoʻohana ʻana i ka manawa o ka plasma kiʻekiʻe e hana i ka ʻoki. Hoʻohana maʻamau ia no ka ʻoki ʻana i nā mea me ka mānoanoa a hiki i 100 mm. ʻAʻole like me ka ʻoki ahi, wikiwiki ka ʻoki ʻana i ka plasma, ʻoi aku ka maikaʻi o ka ʻoki ʻana i nā ʻāpana lahilahi o ke kila kalapona maʻamau, a maʻalahi ka ʻoki ʻia.

  

ʻOki laser

Hoʻohana ka ʻoki ʻoki ʻana i ka kukuna laser ikaika nui e wela, hoʻoheheʻe kūloko, a hoʻoheheʻe i ka metala no ka hoʻokō ʻana i ka ʻoki mea, hoʻohana maʻamau no ka ʻoki pono ʻana a pololei o nā pā kila lahilahi (<30 mm).ʻOi aku ka maikaʻi o ka ʻoki ʻoki ʻana i ka laser, me ka wikiwiki ʻoki kiʻekiʻe a me ka pololei o ka dimensional.

 

ʻOki Waterjet
ʻO ka ʻoki ʻana i ka wai he ʻano hana e hoʻohana ai i nā jet wai kaomi kiʻekiʻe e ʻoki i ka metala, hiki ke hana i hoʻokahi manawa o ka ʻoki ʻana i kekahi mea ma nā ʻāpana ʻokoʻa. No ka mea he wai ka waena, ʻo ka pōmaikaʻi nui loa o ka ʻoki ʻana i ka waterjet ʻo ia ka wela i hana ʻia i ka wā o ka ʻoki ʻana e lawe koke ʻia e ka jet wai kiʻekiʻe, e hoʻopau ana i nā hopena wela.
