Ngā parau hurihuri ahuwhenua kounga teitei, ngā mata whakawātea whenua, ngā mata parau hohonu
Ko ngā mata parau hurihuri he wāhanga matua o ngā mahi a ngā kaiparau hurihuri e mau ana i te tarakihana, e whakamahia ana mō te whakarite whenua i mua i te rui, te whakakoi i te parai raihi, te whakahoki i te kakau witi ki te mara, me te whakatipu māra hua rākau. Mā te huri tere o ngā roera mata, ka tapahia e ngā mata te oneone ka makahia ngā poraka ki muri hei pā ki te taupoki oneone, ka tutuki ai te wehewehenga o te oneone, te whakataurite i te mata, me te whakaranu i te tongi oneone. He huarahi pai tēnei hei whakakapi i te parau tuku iho.
He mea hanga tino ātaahua tēnei raupapa o ngā wīra hurihuri mai i te maitai koranu kounga teitei (pērā i te maitai puna konupora-teitei 65Mn, 60Si2Mn rānei). E whai ana te tukanga hanga i tētahi tikanga paerewa: te whakawātea, te whakamahana, te hanga mate, te wero me te whakakoi, te whakamahana, me te pupuhi pupuhi. Ka pāngia ngā mata e te tineitanga isothermal me te whakamahana, ka hua ake he pakeke taurite i roto i te kakau hei whakarite i te pakari me te ārai i te piko, te whati rānei; ko te mata tapahi, i tētahi atu taha, he pakeke teitei, ā, he kaha te ātete ki te kakahu.
Ko ētahi tauira papai e whakamahi ana i te whakakikorua taiaho matatau, i te hangarau whakarewa koranu ātete-kakahu rānei, hei hanga i tētahi paparanga koranu ki runga i te mata me ngā wāhanga ngoikore o te pito o te mata, hei hanga i tētahi hanganga mata koi-rua-whakakoi, e whakakoi ake ai te mata o te mata i te whakamahinga, ā, e whakaiti ana hoki i te ātete ki te parau.
Mata piko (mata piko maui me te matau): Koinei te momo mata e whakamahia whānuitia ana i tēnei wā. He piko te pane o te mata, he roa te mata tapahi i te pewa o waho, e whakarato ana i te mahi tapahi reti pai rawa atu. I te wā e whakamahia ana, ka ngawari te tapahi, te karo rānei i ngā taru me te kakau witi, he iti ake te tūponotanga o te taru ki te piri, ā, he kaha te kaha ki te pakaru oneone, he mea tino pai mō ngā mara raihi me ngā mara he nui ngā taru.
Mata he āhua whao: He āhua whao te pane o te mata, he kaha te uru ki te oneone, he iti te ātete, he iti hoki te whakapaunga hiko. He pai mō ngā mahi whenua maroke me te whakaora whenua, ā, he tino pai te mahi i roto i ngā āhuatanga oneone taumaha, kiato.
Ngā mata matau tika: He kaha te mahi a ēnei ki te parau, ka huri i te tongi mata ki roto i te oneone o raro, ka whakatairanga i te tohatoha tongi ōrite. He mea whakamahi noa ēnei mō te whakapūpū i te oneone, mō ngā mahi rānei e hiahia ana kia pakaru te papa parau.
Momo-C me te raupapa IT: Pērā i te tauira IT245 noa, he āhua-C ēnei mata me te radius hurihuri motuhake (hei tauira, 245mm). He tino paerewa, he maha ngā whakamahinga, ā, he hototahi ki te nuinga o ngā mata huri hurihuri rongonui o te mākete.
