Nā ʻōwiliʻo ia ke kaʻina hana koʻikoʻi loa ma kake kaʻina hana hoʻokumu anu-kulouNo laila, ʻo ka mea i koho ʻia no ka wili he mea nui hoʻi ia i ka hoʻoholo ʻana i ka maikaʻi o kahimīkini hana ʻōwiliʻO ke koho ʻana i nā mea hana like ʻole o nā wili e hoʻololi nui i ke ʻano o ke ʻano a me ke kumukūʻai hana. Ma ka mākeke mīkini hana wili Kina, ua māhele pinepine ʻia ka mea o nā wili i kēia mau ʻano: 45 kila, 45 kila i hoʻopili ʻia me Cr, GCr15, Cr12, Cr12MOV, etc.
E hoʻololi pū kekahi mau mea hana i nā wili i ka hao hoʻolei i mea e mālama ai i ke kumukūʻai. Pono nā mea kūʻai e hoʻokaʻawale pono i ka wā e kūʻai ai ʻoe i nā mīkini. Ma muli o nā ʻano metala like ʻole o nā mea kemika C, Cr, MO, V, a me nā mea ʻē aʻe o nā ʻano mea i ʻōlelo ʻia ma luna, ʻokoʻa loa ka hana hana a me ke kumukūʻai, no laila ʻokoʻa hoʻi ka hoʻohana ʻana i ka hana ʻana. No nā wili maʻamau me ka ikaika hua ma lalo o 330Mpa a me ka mānoanoa ma lalo o 1.5mm, e like me nā pepa i ʻōwili wela ʻia, nā pepa i ʻōwili anu ʻia, PPGI, kila galvanized, 45 kila a i ʻole 45 kila chromed hiki ke hoʻokō i nā koi. I mea e pale ai i nā wili mai ka popo ʻana a hoʻolōʻihi i ke ola lawelawe o nā wili, hoʻopili ʻo Linbay Machinery i ke kaʻina hana chrome plating i nā wili kila 45 āpau (ʻo ka mānoanoa chrome plating he 0.05mm), a hiki i ka paʻakikī ma hope o ka mālama wela ke hiki i 58-62HRC, ʻo ia hoʻi ka paʻakikī o Cr12 a me GCr15. ʻOiai e hōʻemi ana i nā kumukūʻai, loaʻa iā ia ka maikaʻi maikaʻi i ka manawa like. Inā makemake ʻoe e hana i nā wili ikaika kiʻekiʻe me ka ikaika hua ma mua o 350Mpa a i ʻole nā wili kila kila, e koho ʻo Linbay Machinery iā GCr15 a i ʻole Cr12 ma ke ʻano he mea no nā wili, ʻoi aku ke kumukūʻai. Loaʻa i kēia mau mea ʻelua ke kūpaʻa ʻana i ka ʻaʻahu kiʻekiʻe, ke kūpaʻa wela a me ka ikaika compressive, ka hana holoʻokoʻa maikaʻi loa. I waena o lākou, ua like ka ʻāpana Cr12 me American Standard D3. Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he mea ʻōwili, hoʻohana pinepine ʻia ʻo Cr12 ma ke ʻano he punch, die, a me ka mea hoʻokomo. ʻO ka mea kiʻekiʻe loa o nā wili ʻo Cr12Mov a i ʻole ke kūlana Kepanī SKD11 a i ʻole ke kūlana ʻAmelika D2, he pipiʻi loa ia i hoʻohālikelike ʻia me nā mea ʻē aʻe, he kūpaʻa kiʻekiʻe kona a ʻoi aku ka lōʻihi o ke ola lawelawe. Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he mea wili, hoʻohana pinepine ʻo Linbay Machinery i kēia mea no ka ʻoki ʻana i ka pahi.
Ma luna o nā mea a pau, hiki iā ʻoe ke koho i ka mea o ka wili e like me kāu mau koi pilikino a me ka waihona kālā hoʻopukapuka. E hāʻawi mau ʻo Linbay Machinery iā ʻoe i ka hopena maikaʻi loa no kāu mau koi kikoʻī, i hiki iā ʻoe ke kūʻai i kahi mīkini hana ʻōwili kūpono loa.
