API suau'u tricone vili fa'atau mo fa'atauga
Fa'amatalaga o oloa
Ole vili cone bit ole mea faigaluega e sili ona fa'aaogaina ile suau'u viliina ma le fa'afanua.Tricone bit o loʻo i ai le aoga o le aʻafia, nutimomoia ma sele papa i le faʻavaeina, ina ia mafai ona faʻafetaui i le vaivai, feololo ma le malosi faʻavae. E mafai ona vaevaeina le fasi cone i le milling (nifo uʻamea) cone bit ma TCI cone bit e tusa ai ma le ituaiga o o nifo.
Tricone bit vaega autu
1) So'oga fa'apipi'i na faia e tusa ai ma tulaga fa'ata'atia API ma ISO.
2) E mafai ona matou fetuutuunai le lapopoa e tusa ai ma lau rig.
3)O le taunuuga sili e mafai ona maua e ala i le faaaogaina o le uʻamea nifo uʻamea i le malu stratum.TCI tricone bit e mo le faʻatulagaina faigata.
4) Faʻataʻitaʻiina fausaga tipi ma faʻapipiʻiina o loʻo faʻaauau pea ona tuʻuina atu se maualuga maualuga o le faʻatinoga ma le faʻamaoni.
5) Fa'apena fa'alelei e maua ai le ROP fa'ateleina e ala i le aveeseina lelei o tipi ma fa'amautinoa le fa'aogaina o maa fou i luga o suiga uma o le fausaga.
