utu pūrākau pdc
Ko te utu o ngā PDC bit he whakamarama nui i ngā mahi herehere, e whakaatu ana i te paihere o ngā PDC bits (Polycrystalline Diamond Compact) i roto i te hunga herehere ā-rōpū. E ai ki ngā rautaki herehere tino mōhio, kei runga i aua rautaki herehere ngā kaihere herehere arahe hou, e noho ana i runga i tētahi tinana tungsten carbide, me te whakapakari i te wawata i waenganui i ngā whenua rorohiko. Ka tae te whāriki utu i ngā take pēnei i te whatitiri o te bit, te pai o ngā kaihere, te whaimana o te hoahoa, me te ingoa o te whatuanga. Kei ngā PDC bits hou ka hangaia ngā āhuatanga mōhiko pēnei i te whakarite pai o ngā kaihere, ngā hoahoa wai hirere, me ngā whakatakotoranga mata ohaoha, ko ngā atu katoa enei e whakaaturia ana i tō rātau uara a-aha. Ko te utu e whakaatu ana ki te kore rawa hoki i ngā utu hanga, ēngari ko te wairua hoki o te bit ki te mahi, e kitea ana i ngā ratonga tuatahitanga, te whakatutuki, me te whaiwhai i waenganui i ngā momo whenua rerekē. Kei te whakatika mai ngā paerewa o te whenua me ngā whai hua ā-taiao ki te whakauru i te utu o ngā PDC bits, me ngā whatuanga e tuku ana i ētahi atu rautaki hei whakarite i ngā tohu moni e rerekē ana, ahakoa te whakauru pai i ngā mahi herehere. Ko te mōhio ki te utu o ngā PDC bits he mea nui mō ngā kaiherehere, nā te mea e whaiwhai ana ia i ngā utu o ngā kaupapa me ngā āhuatanga herehere whānui.
