Taupānga
Ko te moka roera te taputapu e whakamahia nuitia ana i roto i te keri hinu me te keri whenua.Ko te moka Tricone te mahi o te awe, te kuru me te kutikuti toka i roto i te hanganga, kia taea ai te urutau ki te hanga ngawari, reo me te pakeke.Ka taea te wehea te moka koeko ki te mira (niho maitai) moka koeko me te moka koeko TCI e ai ki te momo niho.
Nga ahuatanga
E ai ki te rauemi tapahi, ka taea te wehea ki te niho maitai (milling tooth) me te tungsten carbide insert (TCI) tooth roller cone bit.
Ko te TCI Tricone e keri paraire mo te hanga toka reo ki te toka pakeke.
Ko nga paraka TCI tricone te hanga waenga e whakaatu ana i nga whakaurunga whao tungsten carbide ki runga i nga rarangi rekereke me nga rarangi o roto.
Ko tenei hoahoa e whakarato ana i te reiti keri tere me te taapiri i te mauroa o te hanganga tapahi i roto i nga hanganga pakeke reo-waenga.Ko te HSN rapa O-mowhiti he pai te hiri mo te mau tonu.
Ka taea te whakamahi i nga paraka tricone TCI ki te keri i te hanga pakeke me te hanga abrasive.Ka whakamahia nga whakauru tungsten carbide aukati ki nga rarangi o waho hei aukati i te ngaro o te ine moka.Ko te nuinga o nga whakaurunga ahua hemispherical ka whakamahia ki nga rarangi katoa hei whakarato i te mauroa o te tapahi me te roa o te ora.
