ʻO ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu
Pono e ʻoi aku ka paʻakikī o ka ʻoki ʻana o ka mea hana ma mua o ka paʻakikī o ka mea hana. ʻO ke kiʻekiʻe o ka paʻakikī o ka mea paahana, ʻoi aku ka maikaʻi o kona pale ʻana. ʻO ka paʻakikī o ka mea paahana ma ka lumi wela ma luna o HRC62. Hiki ke kiʻekiʻe ka paʻakikī ma mua o ka mea maʻamauʻāpana mīkini CNC.
Ua lawa ka ikaika a me ka paʻakikī
Ke kaumaha nui ka mea paahana i 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 hōʻike i ka paʻakikī o ka mea paahana.
ʻoi aʻe ka pale wela
ʻO ke kūpaʻa wela e pili ana i ka hana ʻana o nā mea paahana no ka mālama ʻana i ka paʻakikī, ke kūpaʻa ʻana, ka ikaika a me ka paʻakikī ma lalo o ka wela kiʻekiʻe. ʻO ia ka hōʻailona nui 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 thermal conductivity o ka mea paahana, ʻoi aku ka nui o ka wela o ka hoʻoili ʻana mai ka mea hana, kahi mea e hoʻemi ai i ka ʻoki ʻana o ka mea hana a hoʻomaikaʻi i ka lōʻihi o ka mea hana.
Maikaʻi ka hana ʻana
I mea e maʻalahi ai i ka hana ʻana a me ka hana ʻana i nā mea hana, pono nā mea paahana e loaʻa nā waiwai hoʻoponopono maikaʻi, e like me ka forging, rolling, welding, cutting and grindability, heat treatment properties and high-temperature plastic deformation properties of tool tool. No ka carbide cemented a me nā mea mea hana ceramic, pono pū kekahi sintering maikaʻi a me nā waiwai hoʻoikaika.
ʻAno mea paahana

ʻO ke kila māmā holo kiʻekiʻe he mea kila kila i haku ʻia me W, Cr, Mo a me nā mea ʻē aʻe. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe a me ka paʻakikī, a me kahi ʻano o ka paʻakikī a me ke kūpaʻa ʻana, no laila ua kūpono ia no ka hana ʻana i nā metala non-ferrous a me nā mea metala like ʻole. Eia kekahi, ma muli o kāna ʻenehana hana maikaʻi, kūpono ia no ka hana ʻana i nā mea hana paʻakikī, ʻoi aku ka pauka metallurgy kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe, nona nā waiwai anisotropic mechanical a hōʻemi i ka deformation quenching, He 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 hoʻohuli CNC, 'oi aku ka maika'i o kāna hana ma mua o ke kila ki'eki'e. 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 ʻo ia e like me nā mea hana.
Ka hoʻokaʻawale ʻana a me ka hōʻailona ʻana i nā carbide cemented no nā mea hana ʻoki
