Rakau Waea Rino WaroHe hua rino hurihuri wera tēnei e tukuna ana i roto i te āhua koiri watea mō te kawe, te rokiroki, me te whakahaere ngāwari. Kāore i rite ki ngā pae tika, ka taea te whakarārangi pai i te tokotoko waea koiri, ka penapena wāhi kawe me te rokiroki. Hei tauira, ka taea te koiri i te tokotoko waea 8mm ki roto i te kōpae tata ki te 1.2-1.5 mita te whānui me te rau kirokaramu te taumaha, he mea pai mō te tohatoha ahumahi nui.
Ko tētahi o ngā painga nui otokotoko waea hurihuri werahe tino pai tōna ngāwari ki te miihini. Ahakoa he rino waro-iti, he rino waro-nui, he rino koranu rānei, he pai te āhua o te tokotoko waea, ā, he ngāwari ki te hanga. Ka taea te kume mātao hei waea rino, te whakatika me te tapahi hei pūtu, hei rivet rānei, te whiri rānei hei mata waea me te taura waea. Nō reira, he whānui te whakamahinga o te tokotoko waea i roto i ngā ahumahi hangahanga, mīhini, motuka, me ngā hua whakarewa.
Ko te kounga te mea nui, ā, he mea hou hokiNgā Rākau WaeaI hangaia ngā mira mō tēnei kaupapa. Mā te whakahaere pakari i te diameter (i roto i te ±0.1mm te nuinga) ka whakarite kia ōrite ngā rahi o te koiri. Mā ngā tukanga whakamatao me te maimoatanga mata e whakahaeretia ana ka hangaia he mata maeneene, he iti te waikura, ka whakaitihia te hiahia mō te whakakanapa i muri mai. He mea nui tēnei mō ngā tīwiri mata maitai waro-nui e whakamahia ana i roto i ngā puna, nā te mea ka pā tika te kounga o te mata ki te roa o te ora o te ngenge.

e hiahiatia ana (OEM&ODM)! Ka whiwhi koe i te utu wheketere mai i a ROYAL GROUP.
1. Tikanga Tākai
Te Huinga RōraKo te waea rino hurihuri-wera he mea here ki ngā whitiki rino, ko te taumaha o ia roera he 0.5–2 tana.
Taupoki ĀraiKa hipokina te mata o te rōra ki te kakahu ārai-wai, ki te kiriata kirihou rānei hei ārai i te makuku me te waikura; ka taea te whakatakoto i tētahi mea whakamaroke ki roto.
Te Tiakitanga me te Tapanga i te MutungaKua tāutahia ngā taupoki pito, ā, kua whakapirihia ngā tapanga e whakaatu ana i te rauemi, ngā whakaritenga, te tau puranga, me te taumaha.
2. Tikanga Kawe
Te Waka RoriKa utaina ngā rōra ki runga i ngā taraka papatahi, ka herea ki ngā mekameka rino, ki ngā whitiki rānei.
Te Kawe RerewēHe pai mō te kawe i ngā rahinga nui; whakamahia ngā poraka whakakī me ngā tautoko hei ārai i te nekehanga.
Te Waka MoanaKa taea te kawe i roto i ngā ipu, i te nuinga rānei; kia tūpato ki te tiaki i te makuku.
