He polycrystalline diamond compact (PDC) te whakamahinga i te paihere huarahi tūmataiti me ngā rautaki kōriki. Ko tēnei matāwhutanga hou e pā ana ki te kohinga here o ngā whatu diamona e whakapūmaia nei i raro i ngā āhuatanga nui me te paewhenua nui, whakauruhia he maha ka kitea ai te whakarite i te take kōriki pai me te pai. E whakauru ana te PDC i te kaiwhakapūmaia i te rau diamona hōu ki runga i te papa tungsten carbide, whakapono atu ki te rautaki pai e āhei ana ki te whakawhana i te pai o te diamona me te pai o te carbide. I whakahoungia ngā rautaki nei i ngā mahi kōriki i waenganui i ngā whenua, in particular i ngā takutaku rongoā me te kaihau, i te kaihokohoko, me te hanga. Ki te whakatakoto o te whiu PDC, ka taea e ia te whakarite i ngā wāhi kōriki pai i te wā e whai ana i te pai whakamutunga, ka whakaae tonu ki te pai o te kōriki i ngā taiao kikino. Ko te whakatika ā-mōhio o ngā rautaki PDC ka whakawhiu i a rātou ki te whakatupu pai me te whakatupu pai, ko ngā whakangāwari uara iti hei whakamana i te pai me te pai kōriki.

Ko te polycrystalline diamond compact (PDC) he maha ngā pūtake nui kei roto ia e whai ake nei i te whakahē, ka mahi tōna kē ki te whiringa i ngā tono whakamahere me ngā tono whatiwhati matua. Tuatahi, ko tōna whiuwhiu herehere nui hei whakapuaki i te oranga o te rautaki, ka heke i te āhua o ngā whakawhiti i te wā i mua, me ngā utu kaimahi hoki. Ko tōna take ki te whakaora i ngā para tae noa iho i ana wā kaiwhakatutuki, ka taea te whakarite i ngā mahi whatiwhati ki te haere atu. I te ao taketake, ahakoa i te mohiotanga tuatahitia o te PDC i runga i ngā whakaae matua, ko ngā oranga whakatutuki whakatupuranga nui me ngā mahi pai ka tuku mai ngā whakaiti moni nui i runga i te wā. Ko tōna tahuri whenua pai o te PDC ka whakamana i tōna whakauru i te wā e whakapā mai ana i ngā wāhu nui, ka whakanuia ia hei pai tōnui mō ngā mahi whatiwhati riro i te raro. Ko tōna rākau polycrystalline ka whakamana i tōna whiuwhiu nui ki te whakapiki, ka heke i te pūnaha o te kore whakapae i te wā ka mahi. Ko te PDC hoki ka taea te whakapai i te whiuwhiu nui ki te whatiwhatitanga, ka whakanuia ia hei pai tōnui mō ngā whenua kōhatu nui me ngā rerekē o era. Ko te iti rawa i te rama i te wā ka mahi, ka heke i te kaiwhakamahi iwi me te whakapā o te uru, ka tukuna te pai o te kaiwhakahaere katoa. Ahakoa, ko te pai o te mahi PDC ka tukuna te pai o te poaka me te pūru rorohiko pai, ka noho tino pai tēnei mō ngā mahi whakamahere whakatakoto. Ko te pai o te PDC ka whakamana i tōna whakamahi mō ngā rōpū me ngā mahi katoa, mai i te whakamahere ira kore ki te kaihau me te hanga, ka tukuna te pai o te whakamahi mō ngā hiahia katoa.

Teitei ake te whanake me te whakarongo ki te mate

Kei te whakamana i te pūnaha tōpū āhuarangi o ngā kawe diamanta polikarihana i te hunga hanganga me te whakatū i te whatu. Ko ngā hapa diamanta hangarua e whakapakarihia ana i waenganui i ngā wāhi whai take, whakamahi mai i tētahi whakawhitinga matihiko, ko te tuhituhi he wharewhare mōhuhinga e hoki nei i te wehe haere. E ai ki tēnei pūnaha tōpū, ka mutu te oranga o ngā taputapu moemoeā, e taea ana ngā taputapu PDC ki te noho i runga i te kotahi rau wa i mua i te mutu i ngā taputapu tokoiti. He nui te hiahia o te pūnaha ki te wehe i te wehewehe, e pai ana i ngā taiao whakaruruhau, kei reira ka pahurehia ngā taputapu nuinga. Ko te whiuwhiu polikarihana e whakaheke tonu i ngā kīrehe, e tirotiro ana i te mea kaore te wehenga o te kino iti ki te wehenga katoa o te taputapu. Ka whakahēnei i te tōpū tēnei, ka heke i muri te utu whakakapi, ka whakaitihae i te wā kati mahi, ka puta ake he whai hua nui i ngā mahi hoko me te pūtake utu.
Te Haere Tūmomo me te Whakamātau Ngaire

Te Haere Tūmomo me te Whakamātau Ngaire

Te whakamātau ā-hua o ngā kōmene kimiora e huringa ana i te rongoā, he tūranga matua nui i te hanganga o te hunga whakaputa. Ka noho pono ngā taputapu PDC ki tō rātou tuhituhinga me te wehewehe atu i ngā wā e whakarerekē ai ngā taputapu tūmatanui. Ko tēnei whakamātau ā-hua ka tangoa i te mīhini matatika e whakangungu ana i te hono i waenganui i ngā kōmene kimiora me te paoro tungsten. Ko te āhua o te rereke o te wai kua kitea i te mahi, ka tohungia te whakawhitiwhiti āhuarangi me te wehewehe atu i ngā wā e whakarerekē ai i runga i ngā rā e roa ana. Ko tēnei whakamātau ā-hua e pai ana i ngā tono whakaputa kino i nga wā e huringa nei ngā hua. Ko te wehewehe ake o ngā taputapu PDC kei te hokinga i te mahi whakaputa, ka whakaae mai ki te whakarite me te whakahaere i ngā kaupapa. Ko te whakamātau ā-hua hoki e hāpai ana i te oranga matua, ina e iti rawa ana ngā taputapu ki te hokohoko i te take o te huringa ā-wā.

Nga painga o te utu me te mahi

Ki te mea he nui ake te tūtohu tuatahi i ngā taputapu PDC (polycrystalline diamond compact) i runga i ngā whakamahi matua, he nui noa ētahi pūtake moni mō te wā e hīkina nei. He nui rawa atu te oranga o ngā taputapu PDC, e whakaheke ana i te waehanga o ngā whakatūpū taputapu, e huri ana ki te iti haere i ngā uiui katoa mo ngā taputapu. Ki te mea he pai rawa te mahi toki o ngā taputapu PDC, ka puta ake he wā e tere ana i ngā wā o te tahua, e whakaheke ana i ngā wā o te mutunga i ngā kaupapa me ngā uiui mahi. He pai rawa anō hoki te mahi tika me te whakaaro tonu o ngā taputapu PDC, ka heke i te wā o te mutunga kauwhau, ka tautoko i te pai o te whakariterite kaupapa me te whakawhiti take. Ko te iti rawa iho i te roroa o te rokonui i te wā o te mahi toki, ka heke hoki i te whakamahinga o te waihape, ka tukuna mai he utu whakahaere e tino pai ana. Ka taea hoki te whakapae i ngā rua kuhu matua me te whai i ngā paiheretanga toki, ka whakatinana i te pai o te moni. Nā te hanga o enei nui, ka kitea he tino pai rawa ake te whakamahinga o ngā taputapu PDC mo ngā mahi tahua matua.
