Nā Rollersʻo ia nā ʻanuʻu koʻikoʻi loa i kakaʻina hana hoʻoheheʻe anu. No laila, ʻo ka mea i koho ʻia no ka wili he kumu nui i ka hoʻoholo ʻana i ka maikaʻi o ka amīkini hana ʻōwili. ʻO ke koho ʻana i nā mea wili like ʻole e hoʻololi nui i ka maikaʻi o ka profile a ma ke kumu kūʻai. I loko o ka mākeke mīkini ʻōwili Kina, hoʻokaʻawale ʻia nā mea o nā wili i nā ʻano: 45 kila, 45 kila electroplated me Cr, GCr15, Cr12, Cr12MOV, etc.
Nui nā mea hana e hoʻololi i nā wili e hoʻolei i ka hao i mea e mālama ai i ke kumukūʻai. Pono nā mea kūʻai e hoʻokaʻawale i ka wā e kūʻai ai ʻoe i nā mīkini. Ma muli o nā ʻano mea 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 nei, ʻokoʻa loa ka hana o ke kaʻina hana a me ke kumukūʻai, no laila ʻokoʻa ke noi i ka hana ʻana. No nā coils maʻamau me ka ikaika o ka hāʻawi ʻana ma lalo o 330Mpa a me ka mānoanoa ma lalo o 1.5mm, e like me nā ʻāpana wela, nā ʻāpana anuanu, PPGI, ke kila galvanized, 45 kila a i ʻole 45 kila chromed hiki ke hoʻokō i nā koi. I mea e pale aku ai i ka wili a hoʻolōʻihi i ke ola lawelawe o nā wili, hoʻohana ʻo Linbay Machinery i ke kaʻina hana chrome plating i nā wili kila 45 (ʻo 0.05mm ka mānoanoa chrome plating), a ʻo ka paʻakikī ma hope o ka mālama ʻana i ka wela hiki ke hiki i 58-62HRC. ua like like me ka paakiki o Cr12 a me GCr15. ʻOiai e hōʻemi ana i nā kumukūʻai, loaʻa ka maikaʻi maikaʻi i ka manawa like. Inā makemake ʻoe e hana i nā wili ikaika kiʻekiʻe me ka ikaika hua ʻoi aku ka nui ma mua o 350Mpa a i ʻole nā wili kila kila, Linbay Machinery e koho iā GCr15 a i ʻole Cr12 i mea no nā wili, ʻoi aku ke kumukūʻai. ʻO kēia mau mea ʻelua i ʻoi aku ke kūpaʻa o ka lole, ke kūpaʻa wela a me ka ikaika compressive, maikaʻi loa ka hana holoʻokoʻa. Ma waena o lākou, ua like ka Cr12 me ka 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, make, a me nā mea hoʻokomo. ʻO ka mea kiʻekiʻe kiʻekiʻe loa o nā rollers ʻo Cr12Mov a i ʻole Japanese standard SKD11 a i ʻole American standard D2, ʻoi aku ke kumukūʻai i hoʻohālikelike ʻia me nā poʻe ʻē aʻe, he kūpaʻa ʻaʻahu kiʻekiʻe 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 maka.
Ma luna o nā mea a pau, hiki iā ʻoe ke koho i nā mea o ka roller e like me kāu mau koi a me ka hoʻopukapuka kālā. 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 ʻōwili ʻoluʻolu loa.
