Ngā roerako te taahiraa tino nui rawa atu i roto i tete tukanga hanga piko-makaririNō reira, ko te rauemi i whiriwhiria mō te roera he mea nui anō hoki hei aromatawai i te kounga o temīhini hanga hurihuri. Mā te whiriwhiri i ngā rauemi rerekē mō ngā roera ka nui te rerekētanga i te kounga o te kōtaha me te utu whakaputa. I roto i te mākete mīhini hanga roera Hainamana, ka wehea te rauemi o ngā roera ki ēnei momo: maitai 45, maitai 45 kua whakakikoruatia ki te hiko ki te Cr, GCr15, Cr12, Cr12MOV, me ētahi atu.
He maha ngā kaihanga ka huri i ngā roera ki te rino maka hei penapena utu. Me āta wehewehe ngā kaihoko i te wā e hoko ai koe i ngā mīhini. Nā te rerekētanga o ngā ihirangi whakarewa o ngā huānga matū C, Cr, MO, V, me ētahi atu o ngā momo rauemi kua whakahuatia ake nei, he tino rerekē te mahi tukanga me te utu, nō reira he rerekē hoki te whakamahinga i roto i te whakaputanga. Mō ngā koiri noa he iti iho i te 330Mpa te kaha whakaputa me te awhe matotoru iti iho i te 1.5mm, pērā i ngā pepa huri wera, ngā pepa huri matao, PPGI, te maitai piauau, te maitai 45, te maitai 45 rānei, ka taea te whakatutuki i ngā whakaritenga. Hei ārai i te waikura o ngā roera me te whakaroa i te roa o te mahi a ngā roera, ka whakamahia e Linbay Machinery te tukanga whakakikorua chrome ki ngā roera maitai 45 katoa (ko te matotoru whakakikorua chrome he 0.05mm), ā, ka taea e te pakeke i muri i te maimoatanga wera te eke ki te 58-62HRC, he rite tonu ki te pakeke o Cr12 me GCr15. I te wā e whakaiti ana i ngā utu, ka whiwhi kounga pai i te wā kotahi. Mena kei te hiahia koe ki te whakaputa i ngā koiri kaha-teitei me te kaha whakaputa nui atu i te 350Mpa, i ngā koiri kowiri tira rānei, ka whiriwhiri a Linbay Machinery i te GCr15, i te Cr12 rānei hei rauemi mō ngā roera, he nui ake te utu. He nui ake te ātete ki te kakahu, te pumau wera me te kaha pēhi o ēnei rauemi e rua, ā, he tino pai te mahi whānui. I roto i ēnei, he rite te wāhanga Cr12 ki te American Standard D3. Haunga te whakamahinga hei rauemi roera, he mea noa te whakamahi i te Cr12 hei rauemi wero, hei rauemi mate, hei rauemi whakauru. Ko te rauemi kounga teitei o ngā roera ko te Cr12Mov, te paerewa Hapanihi SKD11 rānei, te paerewa Amerika D2 rānei, he tino utu nui ki te whakataurite ki ētahi atu, he ātete ki te kakahu, ā, he roa ake te ora ratonga. Haunga te whakamahinga hei rauemi roera, he mea noa te whakamahi a Linbay Machinery i tēnei rauemi mō te tapahi i te mata.
Heoi anō, ka taea e koe te whiriwhiri i te rauemi o te roera kia rite ki ō hiahia me tō tahua haumi. Ka hoatu tonu e Linbay Machinery te otinga pai rawa atu mō ō hiahia, kia taea ai e koe te hoko i tētahi mīhini hanga roera tino pai.
