3. Tīmatahia te papu me te huri i te wai keri ki te horoi i te kohao i te wa e wiri ana ki tetahi waahi tata ki te 30 mita ki raro o te poka, ka huri i te aho wiri i te tere iti kaua e neke ake i te 60rpm
4.Whakatata ki raro tata ki te haurua mita.Horoihia mo te 5 ki te 10 meneti me te rere tonu.
5 Reaming
1.Reaming wāhanga roa o undergauge poka e kore e tūtohu.
2.Mehemea e tika ana te mahi reaming, e tino taunakitia ana kia mahia te mahi reaming me te nui o te rere o te rere o te rere, te taumaha motuhake i runga i te moka kaua e neke atu i te 90N/mm (diameter), te tere hurihuri kaua e neke atu i te 60 rpm i te waahi ka mau i te wa e paheke ana. i roto.
6 Moka pakaru-mai
1.Ka nui te whakamahi i nga taputapu whakaatu ina tata te moka ki te poka raro.Mēnā ka piki ake te WOB me te taipana, kua tau mai te moka ki te kohao o raro. Kaua e neke ake i te 90N/mm, te taumaha –i =bit me te 40 ki te 60rpm hei whakarite i te tauira o te kohao raro i te haurua mita.
2.Kua oti te pakaru moka me te whakatika i te RPM kia pai ai te whakakotahitanga tawhā keri.
3.Me whiriwhiria te whakatikatika tawhā keri i roto i nga rohe o nga tawhā e taunakitia ana, tirohia te tikanga arotautanga tawhā keri.
