Ko te putorino maitai hou te ahua o te putorino maitai, he pai rawa atu te ahua nui.I te nuinga o nga wa e rua nga roera mira me te toru-roera mira hanga o nga tukanga whakaputa e rua, e toru-roera mira hanga o te matao o te mira miraka hiko he teitei ake, ka taea te whakahaere i roto i etahi hiraka, engari he nui te utu.Ko te whakatairanga o te teitei -precision ngongo maitai toka matao ki te whakaora maitai, te whakapai ake i te pai o te tukatuka, te whakaora i te kaha Ko te mea e kiia nei ko te tino-tiketike-te-tiketike-to-te-a-ringa te ngongo maitai e pa ana ki te tika o roto me waho (te awhe manawanui) he tino kaha, o roto me te mata o waho. te whakaoti, te porowhita, te tika, ka taea te whakaora i nga haora miihini, te whakapai ake i te whakamahi rawa, me te awhina ki te whakapai ake i te kounga o nga hua.
Ko nga tikanga tukatuka matao nui o te putorino maitai ko te tuhi matao me te tikanga hurihuri makariri.I roto i nga tau tata nei, me te whanaketanga o te pūtaiao me te hangarau, me te whanaketanga o te tikanga miro matao, ki tenei tikanga e taea te whakaputa i te diameter nui, tiketike-pū ngongo matao-hurihia, me ngongo matao-hurihia ki te taurangi ripeka-wāhanga.Tukatuka makariri o te maitai putorino rauemi raw e taea te wera-hurihia paipa paipa maitai taea hoki te paiherea putorino.Ko te ahua noa o te tikanga tukatuka matao o te putorino maitai ko te tika ahu tiketike, te taratara mata pai, ka taea te whakaputa tino kikokore (tae atu ki te 0.05 ~ 0.01mm) ngongo angiangi-taiepa me te tino pai (diamita ki te 0.3 ~ 0.1 mm) te kapi. ngongo.Ko nga putorino rino kore he putorino me te waahanga whitinga tuwhera, e whakamahia ana i roto i nga rahinga nui hei paipa mo te kawe wai, penei i nga paipa mo te kawe hinu, hau maori, hau, wai me etahi mea totoka.Ki te whakatauritea ki te rino totoka penei i te rino porowhita, he mama ake te taumaha o te paipa rino ina rite te kaha o te piko me te kaha toromoka, he maitai ohanga ohanga, e whakamahia nuitia ana i roto i te miihini paipa.
Ko te whakatairanga me te tono o nga ngongo rino maatao-a-matao-nui hei whakaora i te maitai, te whakapai ake i te pai o te tukatuka, te whakaora i te kaha Ko nga mea e kiia nei ko nga ngongo rino korere e kiia nei ko te tino tika o roto me te taha o waho (te awhe manawanui) he tino, o roto, o waho hoki te mutunga o te mata, te porowhita, te tika he pai, ka taea te whakaora i nga haora tukatuka miihini, te whakapai ake i te whakamahinga rauemi, me te awhina ki te whakapai ake i te kounga o te hua.
