Raupapa: He aha i kore ai e angitu ngā mata wiri | Tuhinga 9
Ngā Kupumatua: pūwāhi wehewehe 135°, mata wiri pūwāhi wehewehe, koki pūwāhi wiri, koki pūwāhi 118° vs 135°, pūwāhi wiri pokapū-ā-unoa, mata whao, āhua pokapū mata wiri
I tirohia e te tuhinga o mua o tēnei raupapa te take e hikoi ai ngā mata wiri — te reti poto ki te taha i te wā e pā ana, me te take he raruraru āhuahanga, kaua ki te raruraru rauemi. I whai taua tuhinga i te take ki te taha o te whao: te wāhanga kei waenganui o te pūwāhi wiri hurihuri paerewa kāore e tapahi ma, engari ka puta ake, ka nekehia te rauemi. I kati mā te kī ko te huri i te pūwāhi wehewehe ka whakapoto i te taha o te whao, ka whakaiti i te hikoi, ā, ka kapihia e tēnei tuhinga te take i roto i te hohonutanga — tae atu ki te take ko te 135° te koki e tino tohua ana i te taha.
E titiro ana tēnei tuhinga ki ngā rerekētanga o te huri porowhita i te pito, he aha i rite tonu ai te hononga o te koki 135° ki taua huri, me ngā mea me tirotiro e ngā kaihoko i mua i te whakaaro ko te tapanga i runga i te pepa whakaritenga e whakaata ana i te mea i hurihia ki roto i te maitai.
Te Raru o te Tapa o te Whao, i Whakahuatia Anō
He mea hanga te pū werowero takai paerewa mai i ngā ngutu tapahi e rua e tūtaki ana ki te mata o te whao e rere ana i waenganui. Kāore te mata o te whao e kutikuti i te rauemi pērā i ngā ngutu — ka panaia te rauemi ki mua i te pū e pēhia ana. Koia te take e hiahia ana te pū werowero paerewa ki tētahi pū werowero pokapū, ki tētahi kōhao pairati rānei kia tīmata pai ai i ngā mahi maha: ko te roa o te mata o te whao, ko te nui ake o te whakawhirinaki o te pū ki te ōritetanga o te huri anake kia noho pokapū ai, ā, ko te nui ake o te pana tuaka e hiahiatia ana kia ngau ai te werowero.
Ehara te mata o te whao i te hapa o te wiri hurihuri paerewa — he hua ia o te hurihanga o te pito kōniko noa. Engari koinei anō te rīpene nui rawa atu e wātea ana hei whakapai ake i te tīmatanga o te poka e te wiri, koinei tonu te wāhi e mahi ai te āhua o te pito wehewehe.
Te Mahi Tuturu a te Split Point Grind
Mā te pūwāhi wehe ka tāpirihia he mahi huri tuarua ki waenganui o te pūwāhi, ka tapahia tetahi wāhanga o te mata o te whao, ka whakakapia ki ētahi atu pūwāhi poto e rua. He māmā noa te pānga mahi:
• He poto ake te mata o te whao— i te nuinga o te wā ka whakaitihia ki tētahi wāhanga iti noa iho o tōna roa i runga i tētahi pūwāhi paerewa, ka iti ake ngā rauemi e hiahiatia ana kia whakaputahia, kaua e kutikutia.
• E rua ngā tapa tapahi tāpiri e tata ana ki waenganui— ka tapahia te pito inaianei kia tata atu ki te tuaka, kaua e whakawhirinaki ki ngā ngutu o waho anake hei mahi i ngā mahi kutikuti katoa.
• Te pana axial iti iho— he iti ake te kaha e hiahiatia ana hei ngau i te wiri, koia te take e kiia ai ngā wiri pūwāhi he wiri-ā-roto-ake, he wiri-ā-ake rānei.
• Te whakaiti i te whakawhirinaki ki te ōritetanga o te huri anake— he poto ake te mata o te whao, he iti ake te tawhiti hei mahi mā ngā āhua rerekē i waenganui i ngā ngutu e rua i mua i te hononga tika o te pito, ka whakaiti tika i te ia o te hikoi i kōrerotia i te tuhinga o mua.
He aha te 135°, inā koa
Ko te koki pūwāhi me te huri pūwāhi wehewehe he whakatau hoahoa motuhake e rua e tohua tahitia ana, ā, he take miihini anō hoki mō taua hononga. Ko te pūwāhi whānui paerewa e tata ana ki te 118°. Ko te pūwāhi 135° he papatahi ake — he tata atu ki te poutū ki te tuaka keri — ā, ka rerekē tēnei i te tohatoha o te kawenga tapahi:
• Te whai wāhi whānui i te wā tuatahi i whakapā atu ai— ka horahia te kawenga tapahi tuatahi e te koki pūwāhi papatahi puta noa i tētahi wāhanga whānui o ngā ngutu, kaua e kukū ki tētahi pito whaiti, ka whakaiti i te ahotea tihi i te wā e tomo ana.
• He pai ake te whakamahi i ngā rauemi mārō, uaua hoki— ko te tohatoha i te kawenga mai i tētahi pūwāhi whaiti te mea nui rawa atu i runga i ngā maitai kore waikura, ngā koranu kaha ake, me ētahi atu rauemi e arotahi ana te pūwāhi paerewa ki te wera me te kakahu ki te pito.
• Ka tere ake, ka ma ake te tīmatanga, kāore he arataki— mā te koki papatahi me te huri porotaka wehewehe ka taea e ngā taha tapahi e rua o waenganui te uru wawe ki te rauemi, koia te take e whakamahia whānuitia ai ngā wiri porotaka wehewehe 135° i ngā keri kawe me ngā keri ā-ringa ina kore he taputapu hei pupuri i te mata ki waenganui.
• Te whakanui ake i te painga mā te huri i ngā pūwāhi wehewehe— mā te koki papatahi ka nui ake te mata o ngā taha tapahi o waenganui o te pūwāhi pakaru hei mahi, nō reira ka kitea ake te pānga whakapū-ā-roto o te huri pūwāhi pakaru i te 135° i tō te koki pari.
Hei whakarāpopototanga: ka huri te huri ira wehewehe i te mea e tupu ana i te taha o te whao, ā, ka huri te koki 135° i te tohatoha o te kawenga mai i taua huri puta noa i te pito. Kāore tetahi o ēnei e whakakapi i tētahi atu — he wāhanga tautoko rāua nō te kaupapa hoahoa kotahi.
He aha te tikanga o tēnei mō te kaihoko
Ko te whakatakotoranga o te pūwāhi wehewehe 135° e whakaahua ana i te āhuahanga e hiahiatia ana, ehara i te hua kua whakamanahia. Ko te tika o te hurihanga te mea e tutuki ai taua hiahia, ā, ka kitea te āputa i waenganui i ngā mea e rua i roto i ngā huarahi e taea te matapae:
• Ahakoa te tapanga pūwāhi wehewehe, ka haere tonu te hikoi.Mena he papaku, he koretake, he kore rānei i waenganui te huri tuarua i te taha o te whao, ka poto noa te taha o te whao, ā, ka whakaatu tonu te wiri i te whanonga haere me te whakaiti i te huri ira wehewehe.
• Te koki pūwāhi kore-taurite puta noa i tētahi puranga.Ko te puranga kua tohua ko te 135° engari he maha ngā nekehanga kei ia taha, ka rerekē te mahi mai i tētahi wahi ki tētahi wahi — ka tīmata pai ētahi wahi, ko ētahi ka tata ake ki tētahi pūwāhi paerewa.
• Ngā tapa pūwāhi wehewehe kore-taurite.Mena kāore i te ōrite te roa, te koki rānei o ngā tapa tapahi tuarua e rua i tāpirihia e te huri ira wehewehe, ka ngoikore te painga o te pokapū, pērā i te ngoikore o te huri ngutu paerewa, ā, ka uaua ake te kite i te hapa me te kore e tirotirohia tata te pito.
Kāore tētahi o ēnei e puta mai i te pānui i tētahi pepa whakaritenga, i tētahi taitara hua rānei. Ka puta mai i roto i te huarahi e tīmata ai te poka i te keri — koinei tonu te āhua o te pūwāhi e tika ana kia whakahaerea i te tuatahi.
Me pēhea te manatoko a ngā kaihoko
Mā ētahi tirotiro ka wehea te pūwāhi wehe tūturu 135° mai i te tapanga e pā ana ki te huri paerewa:
• Pātai atu mō ngā raraunga tirotiro koki pūwāhi,ehara i te koki ingoa anake i runga i te pepa whakatakotoranga. Mā te pānui ine koki-ira, i te ine rānei i te koki-ira puta noa i tētahi puranga tauira e whakaatu mēnā kei te mau tonu te koki, ehara i te mea ko te kī noa iho.
• Tirohia mēnā me werohia tonutia te wiri ki waenganui kia tīmata ma ai.Me tīmata te pūwāhi wehewehe tika me te iti ake o te whakaroa i tērā pūwāhi paerewa i runga i te rauemi kotahi - ki te kore, kāore te huri tuarua e mahi ana i tana mahi.
• Tirohia te pito i raro i te whakanui mō te ōritetanga.Me ōrite te āhua me te rahi o ngā tapa tapahi tuarua e rua i waenganui; ko te kore ōrite i konei he rite ki te wāhi wehewehe o te huri ngutu kore ōrite.
Pērā i te āhua o te hurihanga i kōrerotia i te tuhinga o mua, ko te whāinga hoahoa mō te wāhi wehe 135° he hangarau oro - ko te pātai a te kaihoko katoa mēnā ka tukuna tonutia e te tukanga hurihanga i muri i te tapanga, he puranga i muri i te puranga.
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.
