Rahi noa:
Ka tukuna e mātou ngā hua i te āhua o te waea, te waea papatahi, te waea rīpene. Ka taea hoki e mātou te hanga rauemi ritenga kia rite ki ngā tono a te kaiwhakamahi.
Waea kanapa, kua whakamahanatia, ngohengohe–0.025mm~5mm
Waea mā te whakapūkara waikawa: 1.8mm~10mm
Waea waikura: 0.6mm ~ 10mm
Waea papatahi: matotoru 0.05mm~1.0mm, whānui 0.5mm~5.0mm
Tukanga:
Waea: Te whakarite rauemi→te whakarewa→te whakarewa anō→te hanga→te hurihuri wera→te whakamahana wera→te whakamahana mata→te tuhi (te hurihuri)→te whakaoti whakamahana wera→te tirotiro→te mōkihi→te whare putunga
Ngā āhuatanga o te hua:
1) He tino pai te ātete ki te waikura me te kaha miihini i te pāmahana teitei;
2) Te ātete teitei me te tauwehenga pāmahana iti o te ātete;
3) He tino pai te hurihanga me te mahi hanga;
4) He mahi whakarewa pai rawa atu
