Ua lawa ka ikaika a me ka paʻakikī
Hāʻawi ka mea hana i ke kaomi maikaʻi ma ke kaʻina o ka ʻoki nui ʻana. I kekahi manawa, hana ia ma lalo o ka hopena a me nā kūlana vibration. I mea e pale aku ai i ka haki ʻana a me ka haki ʻana o ka mea hana, pono e lawa ka ikaika a me ka paʻakikī o ka mea paahana. ʻO ka maʻamau, hoʻohana ʻia ka ikaika kulou e hōʻike i ka ikaika o ka mea paahana, a hoʻohana ʻia ka waiwai hopena e wehewehe i ka paʻakikī o ka mea paahana.

ʻO ke kūpaʻa wela e pili ana i ka hana ʻana o nā mea paahana e mālama ai i ka paʻakikī, ke kūpaʻa ʻana, ka ikaika, a me ka paʻakikī ma lalo o nā wela kiʻekiʻe. He hōʻailona alakaʻi ia e ana i ka hana ʻoki ʻana o nā mea hana. ʻIke ʻia kēia hana ʻo ka ʻulaʻula paʻakikī o nā mea hana.
Maikaʻi ka wela wela
ʻOi aku ka nui o ka conductivity thermal o ka mea paahana, ʻoi aku ka nui o ka wela e hoʻoneʻe ʻia mai ka mea paahana, kahi e hoʻemi ai i ka ʻoki ʻana o ka mea hana a hoʻomaikaʻi i kona paʻa.

ʻO ke kila māmā holo kiʻekiʻe he mea kila kila i haku ʻia me W, Cr, Mo, a me nā mea hao ʻē aʻe. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe, ka ikaika, ka paʻakikī, a me ke ʻano o ka paʻakikī a me ke kūpaʻa ʻana, no laila kūpono ia no ka hoʻoili ʻana i nā mea metala non-ferrnonferrous a me nā mea metala like ʻole. Eia kekahi, ma muli o kāna ʻenehana hoʻoponopono kani, kūpono ia no ka hana ʻana i nā mea hana paʻakikī, ʻoi aku ka nui o ka pauka metallurgy kila kiʻekiʻe, nona nā waiwai anisotropic a hoʻemi i ka deformation quenching; kūpono ia no ka hana ʻana i ka pololei a me nā mea hana paʻakikī.
Paʻa paʻa
He kiʻekiʻe ka paʻakikī a me ka pale ʻana o ka carbide sima. Ke okiʻāpana huli ʻo CNC, ʻoi aku ka maikaʻi o kāna hana ma mua o ke kila kiʻekiʻe. ʻOi aku ka lōʻihi o ka lōʻihi o ke kila kiʻekiʻe, akā maikaʻi ʻole kona paʻakikī. Ma muli o kāna hana ʻoki maikaʻi loa, hoʻohana nui ʻia ia ma ke ʻano he mea paahana.
