Kōpae harore porowhita, taputapu harore kōpae ahuwhenua, kōpae harore kokoru/kōpae harore porowhita katoa
1, Ngā Rauemi Tino Pai, Ātete ki te Mau
Ko tēnei raupapa o ngā mata haro porowhita e whakamahi ana i te maitai koranu kounga teitei o te ao, 65Mn (te maitai konupora) 30MnB rānei (te maitai konupora boron) hei rauemi turanga. Mā te tukanga maimoatanga wera pakari (te tinei me te whakamahana i te pāmahana teitei), ka whakarite ngā mata i te pakeketanga o te mata me te pakari pai rawa atu. Ka taea e te pakeketanga o te mata mahi te eke ki te 38-48 HRC, ka ngāwari te whakahaere i ngā oneone onepu, ngā oneone uku taumaha, tae atu ki ngā wāhi kohatu kei roto he kirikiri. Ko tōna ātete ki te kakahu he nui ake i ngā mata haro maitai waro noa, ka whakaiti i te auau o te wā kore e whakamahia mō te whakakapinga i te mara.
2. He hoahoa āhua-ā-papa mō te kaha o te uru ki te oneone. He hoahoa hanganga piko (porowhita) he kōhao rānei kei roto i te hua. Ka tatauhia te kōhao porowhita kia tino pai ai te ātete hurihuri me te pānga hiki oneone; ko ētahi tauira he taha kōhao koi e tapahi ngāwari ana i ngā toenga hua me ngā pakiaka taru, ka whakapai ake i te wehewehe me te whakataurite o te oneone. Ahakoa mō te tango kakau witi, te wetewete oneone, te whakaranu maniua, te tapatapahi kakau witi rānei, ka tutuki te hohonutanga o te parau, ka āwhina ki te hanga i ngā moenga purapura tino pai.
3、Te hanga tika, te whānui o te mahi. Mā te whakamahi i te tukanga tā tino tika, ka whakarite ia mata rake kia ōrite ngā āhuahanga me te tūnga tika o te kōhao whakairi, kia taea ai te whakawhiti pai me ngā rake kōpae me ngā huihuinga rake tōia mai i ngā waitohu matua o te motu me te ao (pēnei i a Recon, Gran, me Dongfanghong). Ka huri tuaruatia ngā taha o te hua, ka hua ake he mata tapahi koi mai i te wheketere, ka taea ai te mahi kaha me te kore e hiahiatia he pakaru.
Ārai waikura, pakari hoki, he whānui te urutau. Ka pania te mata ki te paura, ki te pango rānei hei ārai i te waikura, he tino ātete ki te waikura, ā, ka taea te urutau ki ngā taiao oneone waikawa me te kawakore me ngā āhuatanga mahi haumākū teitei. Kāore e ngāwari te waikura i te wā e rongoatia ana mō te wā roa, ā, ka mau tonu te āhua mahi pai rawa atu.
