Raupapa: He aha i hinga ai ngā mata wiri | Tuhinga 13
Ngā Kupumatua: te mata keri huri tika, te manawanui ki te mata keri whenua katoa, te manawanui ki te mata keri h8, te whakapiko i te tuara o te mata keri, te whakapiko tukutuku, te huri i te taha o te mata keri, te whakaotinga mata o te mata keri, te ōritetanga o te puranga o te mata keri, te keri taunga pokanoa, te manawanui ki te whakakī anō
I roto i te tuhinga whakamutunga o tēnei raupapa, i tirohia ngā huarahi e rua hei whakauru i te putorino ki roto i tētahi wahi maitai - tētahi e tango ana i te rauemi, tētahi e kore rawa e tango. Ka haere tonu tēnei i tētahi atu taahiraa. Ka hangaia ngā wahi huri katoa mā te huri, engari ehara te "huri" i te mahi kotahi. He maha, ia ia e whakahaere ana i tētahi taha rerekē. Ka tirohia e tēnei tuhinga he aha aua taha, me pēhea te kawe atu ki te kōhao e tae atu ai te kaihoko.
He aha ngā mea e tino arohia ana e ngā kaihoko
Kāore i te maha ngā kaihoko e pātai ana mō te maha o ngā hurihanga i mahia e te moka. Ko tā rātou e pātai nei, mehemea ka mau tonu te rahi o ngā kōhao i keria e ia, mehemea ka rite te mahi a te puranga e whai ake nei ki tēnei, ā, mehemea ka taea e te moka te tautoko i tētahi mahi whakararo pēnei i te pato, te reaming, te pēhi rānei. Kāore te "whenua katoa" e whakautu i tētahi o aua pātai - ka whakaingoatia noa te tukanga. Ko te mea e whakatau ana i te putanga ko ngā ine e mau ana i taua tukanga, me te kaha o te piri.
Kāore te Huri e Whakahaere i te Ahu Kotahi — E Whakahaere Ana i te Mekameka o Rātou
Kāore te mata huri katoa e hangaia i te kotahi noa te āhua. He maha ngā mahi huri ka mahia, he rerekē te rahi o ia mahi:
Mā te whānui o waho me te huri taha ka whakatau mēnā ka tau te mata ki roto i te awhi ātete paerewa — ko te ātete whānui paerewa mō ngā wiri hurihuri ko h8, he whakaritenga ā-ao, ehara i te mea ka whakatakotoria e tētahi wheketere anake. Ko te pai o te whakahaere i tēnei mahi ka kitea tika i roto i te putanga radial o te mata ina makahia.
Whakaitihia te tuara: ka iti haere te whānui o waho mai i te mata tapahi ki te kakau. Ka hurihia tēnei whakaitihia kia whakaitihia te waku me te wera i waenga i te taha me te pakitara o te kōhao. Ki te iti rawa te whakaitihia o te tuara, ka taea e te mata te here ki roto i te kōhao; ki te nui rawa, ka ngaro te arataki, ka taea ai e te kōhao te neke ki waho o te pokapū. Ka taea e te huri te pupuri i tēnei inenga kia tika - kāore e taea e te mata hurihuri te pupuri, nā te mea kei te āhua o ngā mate hurihuri, e pakaru ana, e neke haere ana i roto i te kotahi oma whakaputa.
Te whakawhāiti i te whatu: ka piki ake te matotoru o te matua mai i te pito ki te kakau hei whakapakari i te tinana o te mata, me te kore e nui te wāhi e nohoia ana e te pakaru. He āhuatanga anō tēnei e tū motuhake ana i roto i te huri, ā, koinei te mea e whakatau ana mēnā ka peka te mata — ka whati rānei — i waenganui i te kōhao hōhonu.
Te ōritetanga o te putorino ki te putorino: i runga i te mata whenua katoa, ka hurihia motuhaketia ngā putorino e rua. Mena ka neke te takai wira, te tawhā whāngai rānei i waenganui i ngā mea e rua, ka puta he ahua kore ōrite o ngā putorino. E pā ana tēnei ki te — engari he rerekē ki — te pokapū o te pūwāhi, i kōrerohia e mātou i roto i te Tuhinga 9 mō te pūwāhi wehe 135°. Ahakoa te koki pūwāhi whenua tika, kāore e tino ea ngā putorino kāore i te ōrite; ka oma tonu te mata me te iti o te taurite.
He Taurangi Whakahaeretia anō hoki te Whakaoti Mata
He maeneene ake te mata whenua i te mata i hurihia, i hangaia rānei. Ehara i te mea he rerekētanga āhua noa iho tēnā — ka whakaitihia e te mata pai o te putorino te ātete ki te rere o ngā maramara, ā, ka whakaitihia te āhua o ngā maramara ki te whakarewa, ki te tākai rānei ki roto i te putorino. Ka kitea nuitia te pānga i roto i ngā rauemi e ngāwari ana ki te hanga i ngā taha, pērā i te maitai kore waikura me te titanium, ka kitea tonu i te wā e ora ana te taputapu.
Ka ara ake te tuanui i te whenua katoa — Kāore e whakamana i te hua
He mea nui tēnei kōrero: ko te tukanga whenua katoa e whakatakoto ana i te rohe mōrahi mō te tika ka taea te whakatutuki. Kāore e kī taurangi ka tae atu ia puranga ki te taumata tika. Ka taea e ngā moka e rua te whenua katoa, ā, ka rerekē tonu te mahi, nā te mea:
•Ko te wira huri kāore i te whakakakahuhia i te wā tika, ka neke haere atu i te āhua i whakaritea mōna.
•Ki te kore he tirotiro i roto i te tukanga, kāore e tirohia te ōritetanga o te puranga-ki-te-puranga. I runga i tā mātou ake raina, ka whakahaerehia e ngā kaiwhakahaere he tirotiro wāhanga tuatahi i te tīmatanga o ia puranga — e whakaū ana i te diameter o waho me te oma i runga i te whenua tuatahi — ā, ka whai ake ko ngā tirotiro ā-wāhi tonu puta noa i te oma, kaua e kimi i te rerekētanga ā-ahu i muri i te otinga o te puranga katoa.
•Ko te āhua me te tiaki o te taputapu huri tonu e whakatau ana mēnā ka uru te tawhā huri kua whakatakotoria pai ki roto i te manawanui i roto i te mahi.
Arā, ko te "kua oti pai te mahi, nō reira he tika tā mātou mahi" e whakautu ana i te pātai tukanga, ehara i te pātai ōrite. Koia te take e taea ai e ngā kaiwhakarato e rua te tapa he "kua oti pai te mahi" engari he rerekē tonu ngā hua.
Te Tikanga o ēnei Ahu mō ngā Mahi o raro a te Kaihoko
•Ngā kōhao i mua i te pato: ko te ātete ki te whānui o te kōhao ka whakatau i te ōrau o te hononga miro. Ki te nui rawa, kāore e ranea te hononga; ki te iti rawa, ka noho hei mōrearea te pakaru o te kōhao.
•Te whakapūmau: ka tatauhia te tahua o te reamer ki te ātete i mua i te poka. Mena ka rerekē te poka i keria i ia wahi, ka pāngia te roa o te mahi a te reamer me te tika o te whakapūmau.
•Ngā kōhao titi tākai me ngā taunga pokanoa: ka mau ngā wāhanga e rua mā te hanga i te kakau kia paku nui ake i te kōhao, kia puta ai te āhua rerekē me te waku i te taunga pēhi e mau ai ngā wāhanga ki te wāhi tika me te kore he here tāpiri. Ko te pokanoa he torutoru ki te tekau mā rua noa iho ngā maikorona, nō reira, ki te nui rawa te kōhao, kāore e mau te taunga; he iti rawa, ā, ka pakaru pea te wāhanga i te taunga pēhi. Koinei tētahi o ngā whakaritenga tino pakari ka taea te tono kia tutuki i te kōhao kua keria.
•Te keri i te pūwero jig: ko te taunga i waenga i te diameter o te taha o te mata me te poka o te pūwero e whakatau ana i te tere o te pakaru o te pūwero, me te pumau tonu o te tūnga o te kōhao puta noa i te hononga maha-kōhao.
Te Tikanga o Tēnei Ina Whakataurite i ngā Kaiwhakarato
"E whakautu ana te whenua katoa" i te āhua o te āhua o te moka — ehara i te mea mēnā ka taea tonu te whakahoki i taua tika. I mua i te whakataurite i ngā kōrero, he mea tika kia pātai tika atu:
•Ka taea te huri i te wiri ki te ātete h8?
•He paerewa pumau te whakatītaha o muri me te whakatītaha tukutuku?
Kāore te kounga o te hurihanga e whakawhirinaki ana ki te kupu a te kaiwhakarato anake. Ka taea e te kaihoko te tirotiro tika i tētahi wāhanga o te hurihanga: me pupuri te mata ki te māramatanga, me te titiro ki ngā mata o te putorino me te taha. Ko te whakaotinga ōrite, rite tonu, e tohu ana i te hurihanga pumau; he mea tika kia pātaihia ngā tohu wiri e kitea ana, ngā taratara koretake rānei, kāore i te ōrite.
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.
