E kiia ana hoki ngā rawhi puna he rawhi Hapanihi, he rawhi puna hoki. He mea tā mai i te maitai puna i te wā kotahi hei hanga i te āhua porowhita, ā, e rua ngā taringa o te mowhiti o waho hei pēhi ā-ringa. Mēnā me rawhi, pēhia noa ngā taringa e rua kia nui ake ai te mowhiti o roto, kātahi ka taea te uru ki roto i te ngongo porowhita, kātahi ka tukuna te kakau hei rawhi. He ngāwari ki te whakamahi. Ka taea te whakamahi anō.

Kāore he kaha kume o te rawhi puna i tōna āhua tūturu. Me whakauru ki roto i tētahi ngongo porowhita, kotahi te rahi atu i te mowhiti o roto hei whakaputa i te kaha kume.

Hei tauira, ko te ngongo porowhita he 11 MM te whānui, me whai hononga 10.5 MM i tōna āhua tūturu, ka taea te whakapiri i muri i te whakaurunga. Ina koa, he ngohengohe, he mārō te kakano o te ngongo porowhita.

Ko te whakarōpūtanga o ngā rawhi puna e wehewehea ana e te matotoru o te whitiki, arā, ko ngā rawhi puna noa me ngā rawhi puna whakapakari. Ko te matotoru o te rauemi he 1-1.5 MM mō te rawhi puna noa. Ko te 1.5-2.0 MM me runga ake he rawhi puna whakapakari.

Nā te mea he nui ake ngā rauemi e hiahiatia ana mō ngā rawhi puna, ko te maitai puna 65 MN te mea e whakamahia ana i muri i te maimoatanga wera.

Te maimoatanga mata: te Fe/EP.Zn 8 kua whakapūmautia, kua whakakorengia, te maimoatanga tango hauwai e ai ki te QC/T 625.

Ngā Āhuatanga: 1.360° te hoahoa tika o te mowhiti o roto, i muri i te hiri he porowhita ōrite katoa, he pai ake te mahi hiri;

2. Kāore he maimoatanga rauemi taha burr, ka ārai pai i te kino o te paipa;

3. I muri i te maimoatanga whakaheke hauwai whai hua, kāore e hiahiatia kia manukanuka ki ngā raruraru pēnei i te pakaru mō te whakamahinga roa;

4. E ai ki te paerewa maimoatanga mata o Ūropi, ka taea e te whakamātautau rehu tote te neke atu i te 800 hāora;

5. Ngāwari te tāutanga;

6. Whai muri i te 36 hāora o te whakamātautau ngāwari tonu hei whakarite i ngā āhuatanga miihini kaha-teitei
