Raupapa: He aha i hinga ai ngā mata wiri | Tuhinga 10
Ngā Kupumatua: koki pūwāhi o te mata keri, mata keri 118 vs 135, mata keri pūwāhi wehewehe, mata keri HSS, aratohu whiriwhiri mata keri
Ki te tātarihia e koe ngā pātai mō ngā mata keri, ka kite koe i tētahi tauira. Ka pātai ngā kaihoko ko tēhea koki pūwāhi te "pai ake" — 118°, 135° rānei — me te mea he whakapai ake tētahi i tētahi. Kāore. He rerekē te raruraru e whakatauhia ana e ia koki, ā, ko te nuinga o te wā ka puta mai te whakapoauau i te tuhinga hokohoko e whakaaro ana ki te pūwāhi wehe 135° hei whakakapinga whānui, kaua ki tētahi taputapu motuhake mō tētahi mahi motuhake.
E hangaia ana e mātou ngā mea e rua, i roto i te rahinga, mā ngā kiritaki e whakamahi ana i a rāua i ngā huarahi rerekē. Koinei te mea e whakatau ana ko tēhea te mea e tika ana mō te pouaka taputapu a te kaihoko — me te take hoki.
He aha ngā huringa tūturu o te koki pūwāhi?
Ko te koki pūwāhi ko te koki i hangaia i waenganui i ngā ngutu tapahi e rua i te pito o te wiri. E whakaahuatia ana ko "118° te koi ake, 135° te papatahi ake," he tika engari kāore i oti. Ko te mea e whakahaeretia ana e taua koki ko ngā mea e toru:
• Te nui o te pana axial e hiahiatia ana hei tīmata i te tapahi.Ka kukū te kaha o te mata koi ki tētahi wāhi iti ake, ā, ka iti ake te pana e ngau ana. Ka horahia taua kawenga e te mata papatahi ki tētahi mata tapahi roa ake.
• Te whanonga o te mata o te whao.Kāore te mata o te whao — te wāhanga poto kei waenganui tonu o te pito, te wāhi e tūtaki ai ngā putorino e rua — e tapahi. Ka panaia te rauemi ki tahaki. Koinei te pūtake nui rawa o te waku me te wera i te tīmatanga o te kōhao, ā, he rerekē tana whanonga i runga i te koki o te pūwāhi.
• Te hanganga o te maramara.I te 118°, ka rerekē te matotoru o te maramara puta noa i te mata tapahi — he matotoru ake i te kokonga o waho, he angiangi ake i te taha o waenganui. I te 135°, he ōrite ake te matotoru o te maramara, he mea nui tēnei mō ngā rauemi e hanga ana i ngā maramara roa, aho.
Ehara tēnei i te whakaaro. Koinei te take i noho ai ngā koki e rua i te tuatahi, ā, he aha hoki kāore tetahi i te "putanga pai ake" noa iho i tētahi.
He aha i tata tonu ai te 135° me te pūwāhi wehewehe
He mea tika kia whakamāramahia tika tēnei, nā te mea koinei te wāhanga e hē ai te nuinga o ngā aratohu rapu rauemi, e pekehia rawatia rānei.
Kāore te mata o te whao e tapahi — ka puta te rauemi ki waho. Ka piki ake te koki e mahi ai ia i tēnei (tōna koki rake whai hua) i te mea ka papatahi te koki o te pito. I roto i ngā kupu mahi: ka papatahi te pito, ka nui ake te parau o taua wāhanga waenga, kaua te kutikuti. Ko te pito 135°, ki te kore e pāngia, he kino ake te raruraru o te mata o te whao i te pito 118° — ehara i te mea iti iho.
He rerekē tēnā i te whakaaro o te nuinga o ngā kaihoko. Ko te ariā: "He papatahi te 135°, ko te papatahi he ngawari ake, ko te ngawari ake he ngawari ake te tīmatanga." Ko te mea pono, he nui ake te koki o te pūwāhi 135° kāore i wehea i te pūwāhi 118° paerewa, nā te mea ko te āhuahanga e tika ana kia pumau ai i ngā taha o waho ka kino ake te pokapū.
Ko te āhua o te pūwāhi wehewehe he mea motuhake hei whakatika i tēnei. Ka hurihia e ia ētahi atu tapa tapahi e rua ki roto i te mata o te whao, ka hurihia taua wāhanga pokapū kāore e tapahia hei mata tapahi tūturu. Koinei te mea e hoatu ana ki te pūwāhi wehewehe 135° tōna whanonga pokapū-ake me tōna pana tīmatanga iti iho - ehara i te koki pūwāhi anake.
Koinei anō te take e hokona ngātahitia ai ngā mea e rua. Kāore e tino pai te mahi a te pūwāhi 135° kāore he āhua pūwāhi wehewehe i roto i ngā tono e whiriwhiria ana te 135° — he kōhao tika i roto i ngā rauemi mārō, he mahi CNC kāore he wero i waenganui, he keri ki roto i ngā mata piko, pahekeheke rānei. Kāore he painga i mahue ina pekehia e koe te taahiraa pūwāhi wehewehe, nō reira he iti noa ngā kaihanga e tuku ana i taua huinga. Ehara i te ture pakari o te āhua. Ko te 135° kāore he pūwāhi wehewehe ka hinga i tana ake kaupapa.
He whakaaro hē tēnei e tika ana kia whakatikahia tonutia: kāore te pūwāhi wehewehe e motuhake ki te 135°.Kei te wātea te pūwāhi wehewehe 118°, ā, e whakamahia ana — ko te nuinga o te wā e hiahia ana te kaihoko ki te iti o te pana me te whānui o te whakamahinga o te 118°, engari me pai ake te pokapū i te pūwāhi paerewa 118°, me te kore e neke ki te āhua papatahi, ātete ki te mau o te 135°. Kāore i te tino kitea nā te mea ko te nuinga o ngā tono 118° kāore e hiahia ana ki taua taumata o te tika o te pokapū i te tuatahi, engari he whirihoranga tūturu, ka taea te hanga — ehara i te mea motuhake.
Ehara te Koki Pūwāhi i te Kōrero Katoa — He Rerekē te Whanoke o ngā Rauemi
Mā te whakaaro ki te koki pūwāhi hei taurangi kotahi e whakatau ana i te angitu o te keri ka māmā ake te raruraru. Anei ētahi tauira e pakaru ai te ture "he rauemi mārō ake, he koki papatahi":
•Konumohe:Kāore i te nui te koki pūwāhi i konei i te koki porowhita me te koha ngutu. Ka tere te whakakore i ngā maramara e te wiri he koki porowhita teitei (34°–38°) me te koha ngutu nui hei ārai i te taha hangai — te aratau rahunga tūturu i roto i te konumohe — ahakoa he 118°, he 135° rānei te pūwāhi.
•Rino maka:Ka puta he maramara poto, he kirikiri, kaua he maramara roa, nō reira kāore i te tino hira te painga o te 135° ki te tango maramara i konei, engari i ngā rauemi e whakaputa maramara tonu ana. He maha ngā toa e whakahaere ana i te 118° ki runga i te rino maka, kāore he raruraru.
•Kowiri tira:Koinei te wāhi e whiwhi ai te ingoa o te pūwāhi wehenga 135°. Ka whakapakeke te kowiri tira i raro i te waku, ā, ko te mahi parau a te mata o te whao i te tīmatanga o te kōhao te mea e whakaoho ana i taua whakapakeketanga. Ehara i te mea whiriwhiri te whakaiti i taua waku mā te āhua pūwāhi wehenga mēnā e hiahia ana koe ki te kounga kōhao ōrite puta noa i te wā whakaputa.
•Kirihou me ngā mea honohono:Ka huri kē te whakaaro. Me whai mata koi ake ēnei rauemi, kaua e koi ake, kia kore ai e ngatata, e pakaru rānei i te putanga mai o te wiri i te rauemi. Kāore e pā te aratohu koki mata paerewa mō te keri whakarewa.
He rite tonu te tauira i konei ki tā tātou i kite ai puta noa i ngā momo rahunga katoa o tēnei raupapa: kāore i te maha ngā tau pepa whakatakotoranga e whakaatu i te katoa o te kōrero. Ka taunekeneke te koki ira me te koki porowhita, te whakawātea ngutu, me te matotoru o te tukutuku. Ki te whakaarohia he whakatau takitahi, ka mutu ko te mutunga o te hoko i tētahi mata wiri e tika ana i runga pepa, engari he hē i roto i te mahi.
He aha te tikanga o tēnei mō te rapu rauemi
Mena kei te whakarite koe i ngā mata wiri mō tētahi toa rauemi whakauru, ka taea e te 118° te whakamahi whānui hei utu mō te nuinga o ngā mahi o ia rā, ā, he iti ake te utu. Mena kei roto i tō mahi he kowiri tira, he koranu rino, he rauemi whakapakeke rānei — ki te kore rānei e taea e tō tukanga te whakamahi i tētahi taahiraa wero i waenganui — ehara i te mea pai te pūwāhi wehewehe 135°, engari he mea nui kia mau tonu ngā ātete me ngā wā huringa.
Ka whai hua anake te koki kua tāia ki te pepa whakaritenga ina mōhio koe ki te raruraru e whakatauhia ana e ia. Ehara i te mea he kino te koki wiri e hikoi ana, e reti ana, e pakaru ana rānei i te wā wawe — tera pea he koki piko hē noa iho mō te mea i tonoa kia mahia.
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.
