Ko te whitiki mīhini whakakoi whakarewa korehau e whakamahia ana mō ngā wāhanga pereti papatahi, te pereti kowiri tira, te pereti maitai waro, te pereti konumohe, te pereti parahi, te koranu titanium, ngā momo konganuku kore-ferrous katoa, te rapa me ngā rauemi kirihou, pērā i te tango i ngā pakaru, te whakakoi me te huri, he maeneene ake te whakamahinga o te mata.

Ngā momo matua me ngā āhuatanga o te tauira whitiki o te mīhini tuhi oro

Ka pā tika te tauira whitiki o te mīhini tuhi oro ki te pānga o te maimoatanga mata me te whai huatanga o ngā taputapu. Ka taea te wehewehe i ngā tauira matua ki ngā wāhanga e 5 e whai ake nei:

1. tauira tika (tauira whakarara): he rārangi tika te whakaritenga o te tauira, ā, ko te hohonutanga he 0.5-1.2mm te nuinga. Ko te painga he ōrite te waku, he pai mō te whakakanapa pai o te maitai kore waikura me te konumohe, engari he ngāwari ki te rakuraku toenga.

2. tauira whakarara (tauira herringbone): ko te koki whakarara ko te 30° - 45°, ko te hōhonutanga o te 1.0-1.5 mm, mā te kaha whakawhiti hei whakaiti i te ngaronga rauemi, e whakamahia whānuitia ana i roto i te whakakanapa parahi, ka piki ake te whai huatanga mā te 20% pea (Pūtake: Pūrongo whakamātautau a Germany ContiTech).

3. tauira whatunga: he hanganga taimana, he tapawhā rānei, he hohonu 1.2-2.0mm, e whakamahia ana mō ngā konganuku pakeke (pērā i te koranu titanium), ka taea te whakamarara i te ahotea, ka whakaroa i te roa o te whitiki ki te 1.5 ngā wā o ngā tauira noa.

4. Tauira ngaru: he hoahoa piko tonu, he hohonu 0.8-1.5mm, he pai mō te mahi piko, ka taea te whakaiti i te koki mate o te oro, engari he ngoikore te ātete ki te kakahu.

5. Wiri hiato: he whakakotahitanga o te wiri tika me te wiri piko, te hohonutanga 1.0-1.8mm, he kaha te whakamahi, engari he nui ake te utu, e whakamahia ana mō ngā wāhanga motuka me ētahi atu miihini tika.
