Paru Mahi Taumaha, Taputapu Tarakihana Ahuwhenua, Mata me te Mata o te Kaiparau Ātete-Kakahu mō te Tahuri Oneone
Hei wāhanga matua, he wāhanga ngāwari hoki te pakaru o te mīhini parau, ka mahi tika te hea parau i ngā mahi nui o te tapahi, te wawahi, me te huri i te oneone. Ka pā tika tōna kounga ki te whai huatanga o te parau, te whakapaunga wahie, me te taiao tupu hua. He mea hanga motuhake tēnei hua mō ngā taiao whakatipu whenua maroke me te mara raihi, ā, he hototahi ki ngā momo parau hurihuri matua, ngā parau papa pokepoke, me ngā parau oneone raro i te motu me te ao.
E rua ngā rauemi e wātea ana mō te mata parau: te maitai puna 65Mn me te maitai boron ātete-mau nui. Whai muri i te whakamahana whānui, ka eke te mata 65Mn ki te 48-52 HRC te pakeke, e whakakotahi ana i te kaha teitei me te pakari pai, e pai ai mō te whakatipu i te oneone paru noa me te oneone paru. Ko te maitai boron ātete-mau nui, e rongoatia ana ki te tinei wera-whakamātautau, ka whakawhanake i te pānga whakapakari-ake i runga i tōna mata i raro i ngā kawenga pānga, ka whakanui ake i tōna roanga mau neke atu i te 40% ki te whakataurite ki ngā mata parau noa, e tino pai ai mō ngā oneone mārō he nui te kirikiri, he nui rānei te whakakīkī.
Ka whakamahia e te whakaputanga te hangarau hanga tino tika, kia mau ai te piko o te mata o te mata me te ātete o te kōhao whakairi i roto i te ±0.5mm, ka hua ake he piripono ki te pou parau, ā, ka ārai i te wiri, i te kukū rānei o te ahotea i te wā e whakamahia ana. Ka huri tuaruatia te mata o te mata, ka whakakoi, ka whakaiti i te ātete ki te urunga oneone mā te 15%-20%, ka penapena pai i te whakapaunga wahie o te tarakihana.
Mata whakangawari: Mā te whakamahi i te hoahoa mata piko whakangawari koiora-whakamimi, ka rere maeneene te oneone i te taha o te mata, ka hua ake he tango oneone pai rawa atu, ka iti ake hoki te piri o te paru, ā, he tino pai mō ngā wāhi oneone uku.
Paparanga ātete-mau matotoru: Ka whakapirihia he paparanga koranu ātete-mau matotoru 2-3mm ki te pito o te mata me te wāhanga o mua, kia roa ake ai te huringa whakakapinga.
Atanga paerewa: Ka tutuki ngā kōhao whakairinga ki ngā paerewa ISO me ngā paerewa matua o te umanga mīhini ahuwhenua ā-rohe, ā, ka hototahi ki ngā hea parau mai i ngā waitohu pēnei i a Lovol, Dongfanghong, me John Deere.
