Mata poutū o te tāra hurihuri
Ko te mata poutū he taputapu matua e mau ana ki te taha mua o ngā mīhini ahuwhenua, pērā i ngā parau, ngā mīhini oneone raro, ngā mīhini whakakotahi rānei. Ko tōna ariā hoahoa matua he whakatutuki i te tapahi whai hua, iti te whakararuraru i te paparanga parau mā te wero poutū ki roto i te oneone. He rerekē ki te parau hurihuri tuku iho, ki te parau rānei, ko te mata poutū e aro ana ki te tapahi i ngā pakiaka hua, te wawahi i te turanga parau, me te whakapai ake i te hanganga oneone, te hanga i ngā āhuatanga pai mō te rui me te tipu hua i muri mai. He taputapu tino nui tēnei i roto i te parau tiaki hou me te ahuwhenua tika.
1, Whai HuaTe tapahi pakiaka me te tango toenga
He mata tapahi koi me te koki kua arotauhia: Mā te mata tapahi me te koki urunga whenua i hangaia mō te tapahi ka ngāwari te tapahi i ngā pakiaka me ngā toenga mata o ngā hua uaua pērā i te kānga me te raihi, kia kore ai e piri te kakau, kia maeneene hoki te mahi.
2, Ka pakaru pai te turanga parau, ka hohonu ake te paparanga parau
Te parau poutū hōhonu: Ka tapahia poutū e te mata poutū ki roto i te oneone, ka pakaru te turanga parau kua whakapakeketia i hangaia e te parau papaku mō te wā roa.
3、Ka whakaiti i te ngangau o te oneone, ka pupuri i te makuku
Ki te whakatauritea ki te parau hurihuri, he iti noa te whakakorikori o te oneone e te mata poutū. Ka tapahia noa e ia te oneone, kaua e pakaru, e hurihuri rānei. Ka whakaitihia te mimiti, ā, he tino pai mō te whakamahi i ngā rohe maroke me te maroke-haurua.
4, Te Pūmau me te Pono Pai rawa atu
Ngā Rauemi Kounga-Teitei: He mea hanga te mata mai i te maitai koranu kaha-teitei (pēnei i te 60Si2Mn me te 65Mn), e tuku ana i te kaha teitei me te pakari tino pai.
Maimoatanga Wera Matatau: Ka pāngia te mata tapahi e te tukanga tinei me te whakamahana ā-wāhanga, kia tino ātete ai ki te kakahu me te pupuri tonu i te ātete pānga kia kore ai e pakaru, e whati rānei.
Te maimoatanga mata: Ka taea te whakamahi i ētahi tauira ki te paparanga whakarewa ātete-kakahu, ki te rehu tungsten carbide rānei, ka taea te whakaroa i te roa o te mahi i roto i ngā āhuatanga mahi uaua pēnei i te oneone onepu me te kirikiri.
