Ngā taputapu hurihanga mata parau e ōrite ana ki te tarakihana
Ko te pito parau he wāhanga e pā ana ki te oneone e tāutahia ana ki te pito o mua o te tinana parau o ngā mīhini ahuwhenua pērā i ngā parau me ngā mīhini ngaki, e mōhiotia ana ko te pito parau. He rite te āhua ki te tapatoru, ki te whao rānei, ā, ka tapahia tuatahitia ki roto i te oneone i te wā e whakamahia ana, e mahi ana i ngā mahi nui pērā i te tomo, te tapahi, me te pakaru i roto i te oneone. Nā te kaha o te waku me te pānga ki te oneone, he wāhanga ātete-mau me te ngoikore te pito parau, ā, ko tōna mahi me tōna kounga ka pā tika ki te whakapaunga pūngao, te pānga parau, me te auau whakakapinga o te mīhini katoa.
Mō ngā rauemi me ngā tukanga, ko ngā pito parau whakahaere kounga teitei o ēnei rā he mea hanga i te maitai konupora motuhake (pēnei i te 65Mn, U75V) he maitai koranu rānei kua oti te whakamahana motuhake hei whakarite i te kotahitanga o te pakeketanga teitei me te pakaritanga teitei. Ko ngā tukanga hanga matatau ko te hanga whakauru, te whakakāpū, te tinei, me te whakamahana. Hei tauira, i muri i te maimoatanga tukanga whakamahana tinei waro (CQT), ka taea e te paparanga mata o te pito parau te hanga i te hanganga martensitic rite ki te ngira pakeketanga teitei, ka whakapai ake i tōna ātete kakahu; ka mau tonu te pakaritanga kaha o te matua, ā, ka taea te ātete pai ki te pānga o ngā arai pēnei i ngā kōhatu i te wā e whakahaerehia ana, ka ārai i te pakaru.
Ka whakamahia hoki e ngā hua kounga teitei te hoahoa pakeke piki me te heke: ko te pakeke o te mata kakahu he 53-60HRC, neke atu rānei, hei ātete i te kakahu, ko te pakeke huri noa i ngā kōhao pūtu tāutanga he iti noa iho hei pupuri i te kirihou pai, hei ārai hoki i te pakaru o ngā kōhao pūtu i te kukū o te ahotea.
Mō te hoahoa hanganga, kia urutau ai ki ngā āhuatanga oneone rerekē me ngā whakaritenga whakahaere, kua whanake haere ngā pito parau ki ngā momo āhua rerekē. Hei tauira, ka taea e te pito parau koi i hangaia mō te oneone piri me te taumaha te whakaiti i te piri o te oneone me te whakaiti i te ātete ki te kukume; ka taea te huri i te pito koko rua-upoko me te whakamahi tonu i muri i te tawhito o tetahi pito, ka rua te roa o tōna oranga mahi. Hei tāpiri, ko ētahi pito parau wetewete hohonu kua hangaia kia rite ki te āhua o te pane hipi hei whakapai ake i te pai o te huri oneone me te whakaiti i te whakapaunga pūngao mā te arotau i te hanganga āhuahanga.
I te whanaketanga o te hangarau, kua noho te ātete ki te kakahu hei tohu matua mō te ine i te kounga o ngā pito parau. Kua eke te ātete kakahu o ngā hua matua o te whare ki te toru ngā wā i tērā o ngā hua noa, ā, ka taea e te roanga mahi kotahi te neke atu i te 80 hāora, neke atu rānei, ka tino whakaiti i te wā kore mahi me te wā whakakapinga i ngā mahi ahuwhenua, ka whakarato i te taurangi pakari mō te whakatipu pai i roto i te ahuwhenua hou.
