ʻO ka ʻoki ʻana kekahi o nā ʻenehana koʻikoʻi o ka mīkini kaʻa.ʻO kāna hana nui ka wehe ʻana i nā mea keu ma ka mea hana ma ka ʻoki ʻana e kiʻi i ke ʻano a me ka nui i makemake ʻia.ʻO nā kaʻina hana ʻoki mīkini kaʻa maʻamau i hoʻohana ʻia e like me ka huli ʻana, hoʻoluhi, wili, wili a pēlā aku.Ma waena o lākou, ʻo ka huli ʻana ke ʻano hana maʻamau i hoʻohana ʻia.Hoʻololi ia i ka mea hana a me ka mea hana e ʻoki ai i ka mea hana ma ka ʻili o ka mea hana e loaʻa ai ke ʻano a me ka nui i makemake ʻia.Loaʻa ʻia ka ʻoluʻolu ma ka hoʻohuli ʻana i ka mea hana a me ka mea hana i ʻoki ʻia ka mea hana ma ka ʻili o loko o ka mea hana e loaʻa ai ke ʻano a me ka nui o loko i makemake ʻia.ʻO ka wili ʻana ma ka hoʻololi ʻana i ka mea hana a me ka mea hana i ʻoki ʻia ka mea hana ma ka ʻili o ka mea hana e loaʻa ai ke ʻano o ka mokulele a me ka ʻili.ʻO ka wili ʻana, ʻo ia ka hoʻohuli ʻana i ka bit drill a me ka mea hana i ʻoki ʻia ka bit drill ma ka ʻili o ka mea hana e loaʻa ai ke ʻano a me ka nui o ka lua.

Ma waho aʻe o ka ʻoki ʻana, ʻo ka mīkini kaʻa kaʻa pū kekahi me ka mālama wela a me ka mālama ʻana i ka ʻili.ʻO ka hoʻomaʻamaʻa wela e pili ana i ka hoʻololi ʻana i ke ʻano a me nā waiwai o nā mea metala ma o ka hoʻomehana ʻana a me ka hoʻoluʻu, a laila e hoʻomaikaʻi ai i ko lākou paʻakikī, ikaika a me nā waiwai ʻē aʻe.ʻO nā ʻano hana lapaʻau maʻamau i hoʻohana ʻia me ka quenching, tempering, normalizing, a me ka annealing.ʻO ka hoʻomaʻamaʻa ʻili ʻana e pili ana i kahi ʻano o nā lāʻau lapaʻau ma ka ʻili o ka mea hana e loaʻa ai ke kūpaʻa ʻaʻahu, kūpaʻa corrosion, aesthetics a me nā mea hoʻonaninani.ʻO nā ʻano hana lapaʻau maʻamau i hoʻohana ʻia i ka electroplating, spraying, sandblasting, polishing, etc.

He hana koʻikoʻi loa ka ʻenehana mīkini kaʻa i ka ʻoihana ʻenehana hou.Me ka hoʻomohala ʻana o ka ʻoihana kaʻa, hoʻomaikaʻi mau ka ʻenehana mīkini kaʻa, kahi e hoʻomaikaʻi nui ai i ka hana, palekana a me ka hōʻoluʻolu o nā kaʻa.I ka wā e hiki mai ana, me ka puka mau ʻana o nā kaʻa hou e like me nā kaʻa ikehu hou a me nā kaʻa akamai, e hoʻomau a hoʻomaikaʻi ʻia ka ʻenehana mīkini ʻenehana, e hāʻawi ana i ke kākoʻo ʻenehana paʻa no ka hoʻomohala ʻana i ka ʻoihana kaʻa.
