Whakaahuatanga Hua

5 1-4 inihi 133mm IADC126 ngā mata keri toka

Ngā moka tricone niho mira(e kiia ana hoki ko ngā mata kōne maitai), he mea hanga ki ngā rauemi koranu kaha-teitei mai i ngā kaihanga mata kōne tricone. Ehara i te mea ko te whakapai ake i te ātete pānga o ngā niho anake tā mātou e ngana ana, engari ko te whakapai ake hoki i te pānga kutikuti me te tawhiti reti o te wiri. Ināianei, ka taea te whakamahi pai i tēnei taputapu i roto i te hangarau keri hou, e kore e taea anake te whakaiti i te tūponotanga o ngā niho whati, engari ka arotau hoki i te whakaritenga o te maha o ngā niho me te maha o ngā niho, me te whakamahi katoa i te mahi a te mata mira niho.

I roto i te tukanga hanga o te koeko moka, ka whakamahia he koranu ā-roto kua whakarewahia ki te kōhao, ka taea te whakapai ake i te kaha ngau o te peera ki tētahi taumata, ā, ka tāutahia hoki hei whakawhāiti i te rerekētanga pēhanga me te ārai i te paru kei uru ki te pūnaha whakahinuhinu, he taputapu hiri rapa. Ka taea te whakapai ake i te kaha me te roa o te mahi o te pūnaha whakahinuhinu hiri o te mata wiri.

Whakatakotoranga Hua

Ko ngā mata tricone niho rino e kiia ana ko te mata tricone niho mira, ko te tikanga o te "maitai" he rino te rauemi o ngā niho, he momo maitai motuhake 15MnNi4Mo, ā, ko te mata o te rauemi maitai he mata pakari ki te Tungsten Carbide hei whakanui ake i te ātete ki te kakahu.
Ko te tikanga o te mira ko te whakamihia o ngā niho e te mīhini mira, nō reira he ingoa anō ō ngā mata tricone niho maitai ko "ngā mata tricone niho mira" ko "ngā mata tricone niho mira rānei".
Ko te 26 inihi te whānui o te kōhao tuatahi i te keri poka hohonu, he ngohengohe tonu ngā hanganga i te wāhanga pāpaku, nō reira e whakamahia whānuitia ana te 26 inihi puta noa i te ao.
