Tetāera arai uku ātete ki te kakahuKo te tikanga, he rite tonu te hanga ki te pokepokea i te wā e hangaia ana, ā, he rite tonu te āhua o te tāera uku ātete-kakahu, nō reira me tapahi i te wā e hangaia ana. Heoi, he uaua ki te tapahi i te tāera uku alumina, nā te mea he teitei te pakeke o te arai uku alumina, ā, ko te pakeke Rockwell o ngā arai uku alumina neke atu i te 92% kei runga ake i te 80, ā, kāore te pakeke o ngā wira huri whānui i te rahi. Kāore e taea te tapahi, engari me whakamahi noa i te mata kani taimana.
Ka whakamahia e mātou ngā mata taimana he tino pakari mō te tapahi. He mīhini tapahi papamahi me ngā mīhini tapahi ringaringa nui, mena he pai te tiaki i a rātou i te wā e tapahi ana, kaua e tapahia te kiri mā te taha o ngā wahi kua tapahia. Kātahi ka kōrerohia me pēhea te tapahi, koinei te kaupapa matua. Engari i kī mai ā mātou tohunga hangarau ina pā te mata hurihuri tere-tere ki te arai uku ātete-kakahu i waenganui, ka pakaru te pereti uku nā te ahotea kutikuti. Nō reira, me tapahi te maripi mai i te pito, kia taea ai te whakaiti i te ahotea, ā, kia kore ai e pā ki te tapahi o te arai uku ātete-kakahu.
Ko te mea whakamutunga ko te aro ki te whakamatao o te mata tapahi. Ina tapahia he rauemi pakeke pēnei, ka tere te piki o te pāmahana o te mata, ka heke te kaha o te mata, nō reira kia aro ki te whakamatao i te mata ki te wai. Hei tāpiri, e hiahia ana ahau ki te whakamahara atu ki a koe: i te wā e tapahia ana, ka tūtohu mātou kia wetewetehia te tuhi, kātahi ka tapahia te rahi, te āhua me te koki uku e hiahiatia ana e mātou kia rite ki te tuhi.
