Kua hangaia ēnei whakaurunga heru kia whakamau ki runga i ngā whāriki motuhake, ā, hei āwhina i te whakakore i ngā kita i roto i ngā momo whakamahinga o te toki porowhita.
Ka haere mai tētahi kiritaki ki a koe me te mahi hanga paipa 90-tohu. E hiahiatia ana he ngongo 2 inihi te whānui mō tēnei tono. He whānui o waho (OD), 0.065 inihi. He matotoru o te pakitara, 4 inihi. He whānui o waenganui (CLR). E 200 ngā wahi e hiahiatia ana e te kiritaki ia wiki mō te tau.
Ngā whakaritenga mō ngā mate: ngā mate piko, ngā mate whakapiri, ngā mate pēhi, ngā mandrel me ngā mate horoi. Kāore he raruraru. Te āhua nei kei roto i te toa ngā taputapu katoa e tika ana mō te piko, ā, kua rite ētahi o ngā tauira. Whai muri i te whakatūnga o te kaupapa mīhini, ka utaina e te kaiwhakahaere te paipa, ka piko whakamātautau kia mōhio ai me whakarite te mīhini. I te hurihanga tuatahi i puta mai i te motuka, ā, he tino pai. Nō reira, ka tukuna e te kaihanga ētahi tauira o ngā paipa piko ki te kaihoko, ā, ka mutu tana kirimana, ka tino arahi ki tētahi pakihi whai hua tonu. Te āhua nei kei te pai ngā mea katoa i te ao.
He maha ngā marama i pahemo, ā, i hiahia tonu te kiritaki ki te whakaiti i ngā utu rauemi. E hiahiatia ana he ngongo 2″ OD x 0.035″ te whānui mō tēnei tono hou. He matotoru pakitara, ā, he 3 inihi te CLR. Kei roto i te kamupene ngā taputapu mai i tētahi atu tono, kia taea ai e te awheawhe te whakaputa tonu i ngā tauira. Ka utaina e te kaiwhakahaere ngā taputapu katoa ki runga i te pēhi pēhi, ā, ka ngana ki te tirotiro i te piko. I puta te piko tuatahi mai i te mīhini me ngā kopa i roto i te piko. He aha ai? Nā tētahi wāhanga o te taputapu he mea tino nui mō te piko i ngā paipa he angiangi ngā pakitara me ngā radius iti: ko te mata horoi.
I te tukanga piko o te ngongo hurihuri, e rua ngā mea ka puta: ka hinga te pakitara o waho o te ngongo, ka angiangi haere, ko te taha o roto o te ngongo ka mimiti, ka hinga. Ko ngā whakaritenga iti rawa mō ngā taputapu piko paipa me ngā ringa hurihuri ko te mata piko e piko ai te paipa, me te mata kume hei pupuri i te paipa i te wā e piko ana i te mata piko.
Mā te mati whakapūmau ka āwhina i te pupuri i te pēhanga pumau ki runga i te paipa i te taha whakarara e piko ai. Mā tēnei ka puta te kaha tauhohenga e hanga ai te piko. Ko te roa o te mati ka whakawhirinaki ki te piko o te wāhanga me te radius o te rārangi pokapū.
Mā te tono tonu e whakatau ngā taputapu e hiahiatia ana e koe. I ētahi wā, ko ngā mati piko, ngā mati whakapūmau me ngā mati pēhi anake e hiahiatia ana. Mena he matotoru ngā pakitara o tō mahi e whakaputa ana i ngā radius nui, kāore pea koe e hiahia ki tētahi mati horoi, ki tētahi mandrel rānei. Ko ētahi atu tono e hiahia ana ki tētahi huinga taputapu katoa, tae atu ki tētahi mati huri, he mandrel, me (i runga i ētahi mīhini) he collet hei āwhina i te ārahi i te paipa me te piko i te papa hurihuri i te wā e piko ana (tirohia te Pikitia 1).
Ka āwhina ngā mati squeegee ki te pupuri me te whakakore i ngā kita i te pūtoro o roto o te piko. Ka whakaitihia hoki te āhua rerekē o waho o te paipa. Ka puta ngā kita ina kore e taea e te mandrel i roto i te paipa te whakarato i te kaha tauhohe e ranea ana.
I te piko, ka whakamahia tonutia te horoi me te mandrel e whakaurua ana ki roto i te paipa. Ko te mahi matua o te mandrel he whakahaere i te āhua o te radius o waho o te piko. Ka tautokohia hoki e ngā mandrel ngā radius o roto, ahakoa ka tautokohia katoatia e rātou mō ngā tono e uru ana ki tētahi whānuitanga iti o ētahi piko-D me ngā ōwehenga pakitara. Ko te Piko D ko te piko CLR wehea ki te diameter o waho o te paipa, ā, ko te tauwehenga pakitara ko te diameter o waho o te paipa wehea ki te matotoru o te pakitara o te paipa (tirohia te Pikitia 2).
Ka whakamahia ngā mate horoi ina kore e taea e te mandrel te whakarato i te mana whakahaere, te tautoko rānei i te radius o roto. Hei tikanga whānui, me whakamahi he mate tango hei whakapiko i tētahi mandrel angiangi. (Ko ngā mandrel angiangi ka kiia i ētahi wā ko ngā mandrel pitch pai, ā, ko te pitch te tawhiti i waenga i ngā pōro i runga i te mandrel.) Ko te kōwhiringa o te mandrel me te mate ka whakawhirinaki ki te OD o te paipa, te matotoru o te pakitara paipa, me te radius piko.
Ka tino hira te tautuhinga tika o ngā mati huri ina hiahiatia he pakitara angiangi ake, he iti ake rānei ngā radius. Whakaarohia anō te tauira i te tīmatanga o tēnei tuhinga. He aha te mea e pai ana mō te 4 inihi. Kāore pea te CLR e pai mō te 3 inihi. Ko ngā panoni rauemi e hiahiatia ana e te CLR me ngā kiritaki hei penapena moni ka haere tahi me te tika teitei ake e hiahiatia ana hei whakatikatika i te matihiko.
Pikitia 1 Ko ngā wāhanga matua o te piko paipa hurihuri ko te whakapūmau, te piko me ngā mate whakapūmau. Tērā pea ka hiahiatia he mandrel hei whakauru ki roto i te ngongo i ētahi tāutanga, ko ētahi ia me whakamahi i te pane tākuta mandrel. Ka āwhina te collet (kāore i te whakahuatia i konei, engari ka noho ki waenganui ka whakaurua e koe te ngongo) ki te ārahi i te ngongo i te wā e piko ana. Ko te tawhiti i waenga i te tangent (te wāhi e piko ai) me te pito o te ūkui ka kiia ko te ūkui ā-ture.
Ko te whiriwhiri i te mate waru tika, te tautoko tika mai i te mate piko, te mate me te mandrel, me te kimi i te tūranga tika o te mate muru hei whakakore i ngā āputa e puta ai te miro me te piko, koinei ngā mea nui ki te whakaputa i ngā piko kounga teitei, kikī. I te nuinga o te wā, me noho te tūranga o te pito heru i waenga i te 0.060 me te 0.300 inihi mai i te pātaki (tirohia te piko o te heru ariā e whakaaturia ana i te Pikitia 1), i runga i te rahi o te ngongo me te radius. Tena koa tirohia ki tō kaiwhakarato taputapu mō ngā ine tika.
Kia tino rite te pito o te mata horoi ki te awaawa o te ngongo, ā, kia kore he āputa (he "pūpū" rānei) i waenganui i te pito horoi me te awaawa o te ngongo. Tirohia hoki ō tautuhinga pēhanga pokepoke. Mena kei te tūranga tika te heru e pā ana ki te awaawa o te ngongo, pēhia mārire te whāriki pēhanga hei pana i te ngongo ki roto i te whāriki piko, hei āwhina hoki ki te whakangawari i ngā kita.
He maha ngā āhua me ngā rahi o ngā huinga horoi. Ka taea e koe te hoko i ngā mate horoi tapawhā/tapawhā mō ngā paipa tapawhā me te tapawhā, ā, ka taea hoki e koe te whakamahi i ngā horoi āhua/āhua hei whakauru i ngā āhua motuhake me te tautoko i ngā āhuatanga ahurei.
Ko ngā momo e rua e tino kitea ana ko te whāriki horoi tuara-tapawhā kotahi-wahi me te pupuri horoi mata. Ka whakamahia ngā mate horoi tuara tapawhā (tirohia te Pikitia 3) mō ngā hua pakitara angiangi, ngā piko-D whaiti (ko te tikanga he 1.25D, iti iho rānei), te rererangi, ngā tono ataahua teitei, me te whakaputa puranga iti ki te waenga.
Mō ngā kōpiko iti iho i te 2D, ka taea e koe te tīmata me te mata horoi tapawhā-tuara, hei whakahaere i te tukanga. Hei tauira, ka taea e koe te tīmata me te waru kōpiko tapawhā-tuara 2D me te tauwehe pakitara o te 150. Tērā atu rānei, ka taea e koe te whakamahi i te pupuri waru me te mata mō ngā tono iti ake te kaha pērā i ngā kōpiko 2D me te tauwehe pakitara o te 25.
Ka tautokona te pūtoro o roto e ngā pereti horoi tapawhā o muri. Ka taea hoki te tapahi i muri i te pakaru o te pito, engari me whakarite e koe te mīhini kia uru ki te mata horoi poto i muri i te tapahi.
Ko tētahi atu momo pupuri mata waru he iti ake te utu, ā, he pai ake te utu mō te hanga piko (tirohia te Pikitia 4). Ka taea te whakamahi mō ngā piko D ngawari ki te piri, tae atu ki te piko i ngā paipa rerekē he rite te diameter o waho me te CLR. Ina kite koe i te pakaru o te pito, ka taea e koe te whakakapi. Ina mahi koe i tēnei, ka kite koe kua whakatakotoria aunoa te pito ki te tūranga kotahi me te mata o mua, ko te tikanga kāore koe e hiahia ki te whakarite i te whakairinga ringa muru. Heoi, kia mahara he rerekē te whirihoranga me te taunga o te kī mata i runga i te pupuri matihiko horoi, nō reira me whakarite koe kei te ōrite te hoahoa mata ki te hoahoa pupuri paraihe.
Ka whakaitihia te wā whakatakoto e ngā pupuri horoi me ngā whakaurunga engari kāore i te tūtohutia mō ngā radius iti. Kāore hoki e mahi me ngā ngongo tapawhā, tapawhā rānei, ngā kōtaha rānei. Ka taea te hanga i ngā heru horoi tapawhā tuara me ngā ringa horoi whakaurunga i te taha tata. Kua hangaia ngā mate horoi kore-pa hei whakaiti i te para paipa, e taea ai te roa mahi poto ake mā te toro atu i te tāpiritanga ki muri i te horoi me te tuku i te collet (poraka ārahi ngongo) kia tata atu ki te mate piko (tirohia te Pikitia 5).
Ko te whāinga he whakapoto i te roa o te paipa e hiahiatia ana, kia penapenahia ai ngā rauemi mō te whakamahinga tika. Ahakoa ka whakaitihia te para e ēnei horoi kore-pā, he iti ake te tautoko e tukuna ana e rātou i ngā horoi tapawhā o muri paerewa, i ngā whakairi horoi paerewa rānei me ngā paraihe.
Kia tino mōhio kei te whakamahi koe i te rauemi waru pai rawa atu. Me whakamahi te parahi konumohe ina whakapiko ana i ngā rauemi mārō pēnei i te maitai kore waikura, te titanium me ngā koranu INCONEL. Ina whakapiko ana i ngā rauemi ngohengohe pēnei i te maitai ngawari, te parahi me te konumohe, whakamahia he horoi maitai, he horoi chrome rānei (tirohia te pikitia 6).
Pikitia 2 I te nuinga o te wā, kāore e hiahiatia he maramara horoi mō ngā tono iti ake te kaha. Hei pānui i tēnei tūtohi, tirohia ngā kī i runga ake nei.
Mēnā he kakau maripi me te mata, he maitai te nuinga o te wā e hangaia ai te kakau, engari i ētahi wā me hanga te kakau me te pito ki te konumohe parahi.
Ahakoa he heru, he pupuri paraihe rānei me ngā mata, ka whakamahia e koe te mīhini kotahi. I a koe e pupuri ana i te ngongo kia mau tonu, whakatakotoria te waru ki runga i te piko me te tuara o te ngongo. Ka mau te pito o te horoi ki tōna tūranga mā te patu i te tuara o te rarangi horoi ki te hama rapa.
Ki te kore e taea e koe te whakamahi i tēnei tikanga, whakamahia tō kanohi me te rūri (rūri) hei tāuta i te mata horoi, i te pupuri rānei i te mata horoi. Kia tūpato, whakamahia tō maihao, tō kamo rānei kia tika ai te pito. Kia kaua te pito e tino whakamua. Me neke maeneene te ngongo i te pito o te mata horoi. Whakahokia te tukanga kia pai ai te piko.
Ko te koki rake te koki o te squeegee e pā ana ki te matihiko. Ko ētahi mahi ngaio i roto i te rererangi me ētahi atu mara e whakamahi ana i ngā ūkui i hangaia me te iti, te kore rānei o ngā rake. Engari mō te nuinga o ngā mahi, ko te koki honga ka whakatakotoria i waenga i te 1 me te 2 nekehanga, e whakaaturia ana i te pikitia 1 hei whakarato i te ātea nui hei whakaiti i te tō. Me whakatau e koe te pari tika i te wā whakatūnga me te whakamātautau i ngā hurihanga, ahakoa ka taea e koe te whakatakoto i ētahi wā i te hurihanga tuatahi.
Mā te whakamahi i tētahi mata horoi horoi paerewa, whakatakotoria te pito o te mata horoi ki muri i te tapawhā. Mā tēnei ka wātea te wāhi mō te kaiwhakahaere ki te neke whakamua i te pito horoi i a ia e pakaru ana. Heoi, kaua rawa e whakairi i te pito o te mata horoi ki te taha tapawhā, ki tua atu rānei; ka kino te pito o te mata horoi.
I te wā e whakapiko ana i ngā rauemi ngohengohe, ka taea e koe te whakamahi i te maha o ngā rake e hiahiatia ana e koe. Heoi, ki te whakapiko koe i ngā rauemi mārō pērā i te maitai kore waikura, te titanium rānei, ngana kia iti rawa te pari o te mata waru. Whakamahia he rauemi mārō kia tika ai te waru, mā tēnei ka āwhina i te horoi i ngā kopa i roto i ngā piko me ngā tika i muri i ngā piko. Me whakauru hoki he mandrel piripono ki tēnei whakatakotoranga.
Mō te kounga piko pai rawa atu, me whakamahi he mandrel me te mati waru hei tautoko i te taha o roto o te piko me te whakahaere i te kore porowhita. Mena ka hiahiatia he squeegee me he mandrel i roto i tō tono, whakamahia ngā mea e rua, ā, e kore koe e pouri.
Hoki atu ki te raruraru o mua, ngana ki te toa i te kirimana e whai ake nei mō ngā pakitara angiangi me te CLR matotoru ake. I te mea kua mau te pokepokea ai te horoi, ka puta pai te ngongo i te mīhini, kāore he miro. Koinei te kounga e hiahiatia ana e te umanga, ā, ko te kounga te mea e tika ana mō te umanga.
