Raupapa: He aha i hinga ai ngā mata wiri | Tuhinga 14
Ngā Kupumatua: te rere o te mata o te keri, TIR, te porowhita o te kōhao, te kōhao nui rawa, te tika o te keri, te rere o te porowhita, te piko o te mata o te keri roa, te tirotiro i te mata o te keri HSS, te rere o te tītaha me te rere o te huri, te tika o te kōhao
I roto i te tuhinga whakamutunga o tēnei raupapa, i tirohia te āhua o te huri e whakahaere ana i te mata huri katoa — te whānui o waho, te whakarara o muri, te whakarara tukutuku, me te ōritetanga o te putorino ki te putorino. Kotahi te rārangi o taua tuhinga i tohu ki mua i tēnei: ko te pai o te hurihanga o te whānui o waho me te taha ka kitea tika i roto i te putanga radial o te mata ina makahia. Ka whakamāramahia tēnei tuhinga. Ko te putanga te wāhi e mau ai te tika o te huri i roto i te tapahi, kāore rānei — ā, koinei te mea nui rawa atu e wehewehe ana i te kōhao porowhita mai i te kōhao nui rawa atu, kāore i te porowhita.
Te Oma, i roto i ngā Kupu Māmā
Tangohia te kupu, ā, kotahi te pātai e pā ana ki te rere o te wiri: he tika te wiri? Ka rere te porowhita o te mata wiri e rite ana te raina pokapū āhuahanga ki tōna tuaka hurihuri i ia pūwāhi i a ia e hurihuri ana. Kāore te porowhita e piko paku ana, e huri rānei i tōna ake pokapū - ka wiri, pērā i te wira kore taurite. Ko taua wiri, e inehia ana ki te tohu waea, koinei te mea e kiia nei e te umanga ko te TIR: te rere katoa kua tohua.
He mea tika kia wehewehea tēnei mai i te hikoi, i kōrerotia e mātou i roto i te Tuhinga 8. Ka puta te hikoi i te wā tonu ka pā te wiri ki te mata — he take taha whao me te āhua o te ngutu, ā, ka mutu i te wā e pā ana ngā taha ki te pakitara o te kōhao. He rerekē te oma: ina whiua te mata me te hurihuri, ka noho tonu mō te tapahi katoa, mai i te pa tuatahi ki te hohonutanga whakamutunga. He raruraru tīmatanga te hikoi. He raruraru tapahi katoa te oma, ā, koia te take e rerekē ai te puta o ōna pānga — ehara i te tūnga o te kōhao, engari i te rahi o te kōhao, te porowhita, me te āhua o te pakitara.
E rua ngā wāhi e puta mai ai te oma
Ina kite te kaihoko i tētahi raruraru oma, e rua ngā take e tino kitea ana, ā, he mea nui te wehewehe i waenganui i a rāua nā te mea he rerekē rawa te otinga.
•Taha-moka (hangahanga):Ki te kore te mata o te wira e tika ana — nā te ahotea toenga i tukuna i muri i te whakamahana, nā te hurihanga rānei me te kore e puritia ki tōna pokapū tūturu — he rerekē te whānui o waho i te tīmatanga. Kāore he nui o te maka tupato e whakatika i te mata o te wira kua kore kē i te pokapū i tōna wehenga atu i te wira huri. He take hangahanga tēnei, ā, kei te whakahaerehia i te wā hurihanga me te tirotiro.
•Tatūnga-taha (taupānga):Ahakoa he korowha te mata o te chuck, te collet rānei kua tawhito, he maramara, he hinu rānei kua mau ki roto i ngā kauae, he nui rawa te piri, he rere rānei i roto i te miro, ka raru pea te mahi ahakoa he mata tika rawa. He āhuatanga tono tēnei, ehara i te hapa o te wiri.
He aha i hiahia ai kia aro nui atu ki ngā mata wiri roa
Ka whakanuia e te roa te hapa tika kua puta kē. Ko te rerekētanga koki iti e kore e taea te ine i runga i te mata poto ka nui ake te huri i te pito o te mata roa - koia anō te take e wiri ai te tokotoko roa i tōna pito i te tokotoko poto mō te nui o te piko. Koinei anō te take he uaua ake te pupuri tika i ngā wiri roa i te wā e huri ana i te tuatahi: ki te kore he tautoko e tika ana i te wā o te tukanga, ka ngāwari ake te hopu i te kopere pakupaku e kore e kitea e te mata roa paerewa. He tika te pātai tika a ngā kaihoko e mahi ana me ngā wiri roa rawa atu, roa rererangi rānei ki te kaiwhakarato he aha te āhua o te mana whakahaere oma mō taua awhe roa, kaua ki te whakaaro he rite ki te whakaritenga roa paerewa.
Te utu mō te kaihoko ki te paunga o te hoko
Nā te mea kei te puta te rere puta noa i te tapahi katoa, he pūnaha katoa ōna pānga, kaua e noho motuhake ki te taha kotahi:
•Ngā kōhao nunui rawa.He nui ake te whānui o te wiri e whitia ana i tōna rahi noa, ā, ka whānui ake te āputa i te pikinga ake o te putanga.
•Ngā kōhao porowhita-kore.Kāore e taea e te wiri kāore e oma tika te tapahi i tētahi kōhao porowhita — ehara tēnei i te tūponotanga, engari he hua ā-pūkaha tika o tētahi taputapu kāore i te pokapū. Ka whai te hapa porowhita i te oma tata ki te kotahi mō te kotahi.
•Te kākahu o te taha kāore i te ōrite.Ka tere ake te pakaru o te taha o te tawhā e pikau ana i te kawenga i tērā taha, ā, nā te mea he kore taurite te pakaru, e kore e kitea ina tirohia wawetia.
•Ngā pakitara kōhao taratara.Ko ngā tohu hurihuri me te āhua taratara he tohu noa iho, inā koa ka piki haere te wai.
•Te poto ake o te ora o te taputapu.Ka heke te ora o te taputapu i te pikinga ake o te wā e pau ana te keri — mā te whakaiti iti i te wā e pau ana te keri ka nui ake te maha o ngā kōhao ka taea e te wiri te tapahi i mua i te hiahia kia huri anō, kia whakakapia rānei.
Ka hono tika ēnei pānga ki te tuhinga whakamutunga. Mēnā ka hurihia te ātete ki te h8 i runga i te pepa, ka ngaro tonu i a ia taua awhi ātete i roto i te kōhao kua oti te whakaoti, ki te kore e whakahaeretia te rere - he mea nui tēnei mō ngā whakaaetanga reaming, ngā taunga pokanoa, me tetahi mahi i raro iho i hangaia i runga i te rahi o mua i te kōhao.
Me pēhea te mōhio o ngā kaihoko ki te wāhi e tū ai te raruraru
Mā te tohu waea e tū ana ki te mata o te poka i makahia ka hoatu tika te TIR — he tairongo ake ngā wiri iti te whānui ki tētahi nui o te oma i ngā wiri nunui, nō reira ka whakawhāitihia te awhe e whakaaetia ana ina heke te whānui.
Haunga te ine, mā te whakamātautau whakakapinga ngāwari ka kitea te take:
•Whakawhitihia ki tētahi atu werowero, ā, ka ngaro te raruraru:Ko te raru kei taua wahi — tōna tika, tōna āhua rānei i hurihia ai.
•Whakawhitihia ngā mīhini, hurihia rānei te pūwero, ā, ka ngaro te raruraru:Ko te raruraru kei te tatūnga — te āhua o te tītaha, te oma o te miro, te piri rānei — ehara i te wiri.
•Kāore tētahi o ngā whakawhiti e whakatau i tēnei:He mea pai kia tirohia te roa o te ārai piri, ngā tawhā whāngai, me te pakari o te pupuri mahi i mua i te whakaaro ko te mata, ko te mīhini rānei te he.
He rite tēnei ki te huarahi tātaritanga o te Tuhinga 8: mā te mōhio ki te pūtake o te take ka whakatau mēnā ko te mahi tika e whai ake nei he kōrero ki te kaiwhakarato, he whakatikatika rānei i runga i te papa o te toa.
Te Tikanga o Tēnei Ina Whakataurite i ngā Kaiwhakarato
He rerekē ngā kereme e rua mō te manawanui huri me te mana whakahaere oma, ā, he mea tika kia pātaihia ngā mea e rua. I mua i te whakataurite i ngā utu:
•Ka tirohia te rere o te konganuku i muri i te huri, ā, i runga i tēhea take — ko te wāhanga tuatahi anake, ko te whakamātautau tonu rānei i roto i te puranga?
•He paerewa motuhake mō ngā wiri roa, roa rawa rānei, i runga i te nui o te roa e whakanui ana i te hapa tika?
•Ka taea e te kaiwhakarato te whakapuaki mai i ngā mea e kitea ana i roto i tā rātou tirotiro — ehara i te mea ko te manawanui e kīia ana i runga i te pepa whakaritenga anake, engari ko tēhea wāhi i roto i te tukanga e manatokohia ana?
I runga i tā mātou ake raina, ka tirohia ngā wahi tuatahi o ngā konganuku whenua kia mau ai te diameter o waho me te putanga i te tīmatanga o ia puranga, ā, muri iho ka tirohia ngā wahi i te tukanga i te tukanga katoa — ko te kaupapa kotahi i whakaahuatia i te tuhinga whakamutunga, e pā ana ki te tika me te putanga radial kaua ki te diameter anake.
Mō tēnei raupapa
He raupapa hangarau a Why Drill Bits Fail nā tā mātou tīma hanga i tuhi. E arotahi ana ia tuhinga ki tētahi āhuatanga motuhake o te mahi a te mata o te wiri - mai i ngā rauemi mata ki te takai. He māmā noa te whāinga: āwhina i ngā kaihoko ki te mārama ki tā rātou e hoko ana, me ngā pātai hei pātai.
