He maha ngā wā ka whakauruhia te mīhini whakairo CNC ki te pouaka whakamatao wai ahumahi hau-whakamatao hei whakamatao i te porowhita i roto. Ko tētahi o ngā wāhanga o te pouaka whakamatao wai hau-whakamatao ko te pana rere. Ka whakamahia te pana rere hei aroturuki i te nui o te rere i roto i te waeine pouaka whakamatao porowhita. Ina teitei ake, ina iti iho rānei te rere o te wai i te pūwāhi kua whakaritea, ka whakaoho i te whakaoho rere, ā, ka tukuna te tohu whakaoho ki te pūnaha whakahaere o te pouaka whakamatao. Kātahi ka hoatu e te pūnaha whakahaere he tohutohu e pā ana ki te pana rere kia kore ai e maroke te rere o te papu wai.
Whai muri i te 18 tau o te whanaketanga, ka whakatūhia e mātou he pūnaha kounga hua pakari, ā, ka whakaratohia he ratonga whai muri i te hoko kua tino whakapumautia. Neke atu i te 90 ngā tauira pouaka whakamatao wai paerewa me te 120 ngā tauira pouaka whakamatao wai hei whakaritenga. Me te kaha whakamatao mai i te 0.6KW ki te 30KW, ka taea te whakamahi i ā mātou pouaka whakamatao wai hei whakamatao i ngā momo pūtake taiaho rerekē, ngā mīhini tukatuka taiaho, ngā mīhini CNC, ngā taputapu hauora, ngā taputapu taiwhanga me ētahi atu.
