He maha ngā āhuatanga o te maitai kore waikura e ātaahua ai mō ngā momo mahi maha, engari mā ēnei āhuatanga anō ka uaua ai te mahi tahi. I te wā e whakamahia ana, ka ngawari te rakuraku me te paru, ka ngawari ai te waikura. Hei whakamutunga, engari ehara i te mea iti rawa, he nui ake te utu i te maitai waro, nō reira ka nui ake te utu o ngā rauemi ina hangaia ngā wāhanga maitai kore waikura.
He nui hoki ngā tumanako a ngā kiritaki mō te kounga o te whakaotinga, me te tono kia rite te whakaotinga ki te whakaata mō tētahi rauemi e whakaatuhia ana hei hua kua oti. He iti noa te tūponotanga ka hunaia te hapa mā te paninga, te peita rānei.
I te mahi tahi me ngā paipa kowiri tira, ka nui haere ēnei raruraru ki tētahi taumata, nā te mea he iti noa te kōwhiringa o ngā taputapu tino pai me te whai hua mō te tukatuka rauemi ngāwari ki te whakaoti.
Nā te ātete ki te waikura, he pai rawa te kowiri tira mō ngā mahi e hiahia ana ki te kanapa tūturu o te konganuku, pērā i ngā wira urungi me ngā okiokinga ringa. Ko te tikanga hoki o tēnei ka rerekē te whānui o waho o te ngongo mai i te hukapapa ki te āhua maeneene, kāore he hapa.
Me whakamahi i te taputapu tika me te taputapu whakakoi tika mō tēnei. Ko te pātai tuatahi ka pātaihia e mātou ki ō mātou kiritaki ko te aha te haumi e pai ana rātou ki te mahi kia tere, kia pumau hoki te otinga paipa e hiahiatia ana. Mō te hunga e hiahia ana ki te pupuri i te rere pumau o ngā ota whakaoti paipa, mā te whakahaere aunoa i te tukanga me te huri kore pokapū, te huri porotaka, tetahi atu momo mīhini whitiki rānei ka māmā ake te wehewehe i ngā wāhanga kia tutuki ai te hua e hiahiatia ana. Ka taea hoki te whakatutuki i te pumau o te hua kua oti mai i te wāhanga ki te wāhanga.
Heoi anō, kei reira anō ngā kōwhiringa mō ngā taputapu ā-ringa. I runga i te rahi o te paipa, he huarahi whai hua te huri whitiki hei whakarite kia kore e rerekē te āhua o te wāhanga i te wā o te tukanga whakaoti. Mā te whakamahinga o te whitiki ngoikore ka taea te mahi i te kōtaha ngongo me te kore e whakawhāiti. E toru ngā pūrei whakapā o ētahi whitiki, e āhei ai te ngāwari ake huri noa i te ngongo. He rerekē ngā rahi o ngā whitiki. Ko ngā whitiki kōnae kei waenga i te 18″ ki te 24″, ko King-Boa ia e hiahia ana ki ngā whitiki 60″ ki te 90″. Ko ngā whitiki kore-waenga me ngā whitiki porotaka ka 132 inihi te roa, te roa ake rānei, tae atu ki te 6 inihi te whānui.
Ko te raruraru o ngā taputapu ā-ringa, he mahi toi te whakaoti i te mahi i ngā wā katoa, ehara i te pūtaiao. Ka taea e ngā kaiwhakahaere mohio te whakatutuki i ngā whakaotinga pai rawa atu mā tēnei tikanga, engari me whakaharatau. I te nuinga o te wā, ko ngā tere teitei ka hua ake he rakuraku pai ake, ko ngā tere iti ka hua ake he rakuraku hohonu ake. Ko te kimi i te taurite mō tētahi mahi motuhake kei te kaiwhakahaere. Ko te tere tīmatanga rīpene e taunakitia ana kei te pūwāhi mutunga e hiahiatia ana.
Heoi, he mea nui kia kaua e whakamahia ngā mīhini huri kōpae, ngā mīhini huri ā-ringa rānei o tētahi momo mō te tukatuka paipa. He uaua ki te tiki i te tauira e hiahiatia ana e koe me ēnei taputapu, ā, ki te pēhia rawatia te mata o te mīhini, ka pāngia te āhua o te paipa, ka hangaia he wāhi papatahi ki runga i te paipa. I te ringa matau, ki te mea ko te whāinga he whakakanapa i te mata whakaata kaua ki te tauira rakuraku, he maha ngā mahi whakakanapa ka whakamahia, ā, ko te mahi whakamutunga he mea whakakanapa i te matū whakakanapa, he rākau whakakanapa rānei.
Ko te whiriwhiri i te mea whakakoi me mārama ki te whakaotinga whakamutunga. He pono, he ngāwari ake te kī atu i te mahi. Ko te tirotiro ā-kanohi te tikanga e whakamahia ana hei whakataurite i ngā wāhanga ki ngā hua o nāianei. Heoi anō, ka taea e te kaiwhakarato mea whakakoi o te toa te āwhina ki te whakatau me pēhea te whakaiti haere i te nui o te mea whakakoi kia tutuki ai te hua e hiahiatia ana.
I te wā e huri ana i te maitai kore waikura ki te mata whakamutunga, he mea nui kia whakamahia he tukanga whakakoi i ia taahiraa. I te tīmatanga, me whakarite kia tangohia ngā paru me ngā pakaru katoa. Me tīmata mā te hua pai rawa atu hei whakatika i ēnei ngoikoretanga; ka hohonu ake te rakuraku, ka nui ake te mahi e hiahiatia ana hei whakatika. I ia taahiraa e whai ake nei, me āta tango i ngā rakuraku mai i te whakakoi o mua. Nō reira, ka tutuki he tauira rakuraku ōrite ki te hua kua oti.
Mō ngā mea whakakoi pania tuku iho, he uaua ki te karo i ngā momo whakakoi kia whiwhi ai i te āhua matte tika ki te maitai kore waikura nā te āhua o te pakaru o te mea whakakoi. Heoi, mā ētahi hangarau ka taea e koe te karo i ngā mahi, pērā i ngā mea whakakoi Trizact a 3M, e pakaru ana i roto i te āhua e "whakahou" ai te mea whakakoi me te kakano hou e kitea ana i a ia e whakamahia ana. 3M
Ko te tikanga, ko te whakatau i te kaha o te taratara o te mea whakakoi ka whakawhirinaki ki te rauemi. Mena me tango e koe ngā hapa pēnei i te unahi, ngā pakaru, ngā karawarawa hōhonu rānei, me whakamahi koe i te mea whakakoi matotoru. Hei tauira, ka tīmata mātou me te whitiki kawe 3M 984F, 947A rānei. I muri i tā mātou neke ki ngā whitiki kirikiri 80, ka huri mātou ki ngā whitiki motuhake ake.
I te wā e whakamahi ana i ngā mea whakakoi kua pania tuku iho, kia tino whakaitihia te whakarōpūtanga o ia mea whakakoi, kaua e ngaro i te āhua o te pakaru o te mea whakakoi kia whiwhi ai i te mutunga matte tika ki runga i te maitai kore waikura. Kia pakaru te mea whakakoi, me nui ake te pēhanga hei whakatutuki i te hua ōrite i te wā e pouri ana ngā kohuke, e tangohia ana rānei i te mea whakakoi. Ka puta te wera i ngā kohuke matte, i ngā kaha teitei ake rānei. Nā te mea he raruraru te wera i te wā e whakaoti ana i te maitai kore waikura, ka pā pea ki te mutunga, ā, ka "kikorangi" te mata.
Ko tētahi atu raruraru ka puta ake me ētahi mea whakakoi utu iti ko te ōritetanga o ā rātou kohuke whakaoti. Ka uaua ki te kaimahi kore wheako te whakarite kia whiwhi te mea whakakoi i te mata e hiahiatia ana i ia taahiraa. Mena he rerekētanga, ka puta pea ngā karawarawa mohoao e kore e kitea tae noa ki te wā whakakoi.
Heoi, kei ētahi tikanga ka taea e koe te peke i ngā taahiraa. Hei tauira, ka whakamahia e te 3M's Trizact Abrasive he ranunga o te kapia me te mea whakakoi hei hanga i tētahi hanganga piramita e whakahou ana i te mata whakakoi me ngā matūriki hou kua kitea ahakoa kua pakaru te mea whakakoi. Mā tēnei hangarau ka whakarite kia rite te mutunga puta noa i te roanga o te whitiki. Nā te mea ka whakaratohia e ia momo rīpene Trizact he mutunga matapae, i taea e mātou te peke i ngā momo mea whakakoi i te mutunga whakamutunga. Mā tēnei ka penapena wā mā te whakaiti i ngā taahiraa oro me te whakaiti i te mahi anō nā te mea kāore i oti te oro.
Ko te mea nui ki te whiriwhiri i tētahi mea whakakoi ko te whakatau me pēhea te whiwhi i te whakaotinga tika i te huarahi e tino whai hua ana, e tino whai hua ana hoki.
Nā te mea he rauemi mārō te maitai kore waikura, he mea tino nui te whiriwhiri i ngā mea whakakoi me ngā kohuke. Mēnā he hē te whakamahinga o te mea whakakoi, ka roa te tukatuka o te rauemi, ka nui ake te wera e puta. He mea nui kia whakamahia te momo kohuke tika, me te whakamahi i tētahi mea whakakoi he paninga whakamarara wera hei tango i te wera mai i te rohe pa i te wā e whakakoi ana.
Mena kei te whakamahi koe i tētahi mīhini, ka taea hoki e koe te whakamahi i tētahi wāhanga o te wai whakamatao, ka āwhina hoki ki te tango i ngā paru, kia kore ai e pakaru te mata i ngā karawarawa paru. Kia tika te whakamahi i te tātari tika kia kore ai e hoki mai anō ngā paru ina hurihia anō te wai whakamatao ki roto i te mīhini.
He whakaaro tō te nuinga he rite tonu te āhua o te maitai kore waikura katoa, engari mō te mata o tētahi wāhanga, ka pāngia te āhua o taua wāhanga e ngā momo kohuke e rua. Kei te kaiwhakamahi tēnei tirohanga.
Hei tauira, ko te tikanga o te warowaihā silicon tuku iho he hohonu ake ngā karawarawa e whakaata rerekē ana i te mārama, ā, e kikorangi ai.
I taua wā anō, ka waiho e te waikura konumohe tuku iho he āhua porowhita ake e whakaata rerekē ana i te mārama, ā, e kōwhai ai te rauemi.
I runga i te rahi o te paipa, he huarahi whai hua te huri whitiki hei whakarite kia kore e rerekē te āhua o te wāhanga i te wā o te whakaotinga. Mā te whakamahinga o te whitiki ngoikore ka taea te mahi i te kōtaha ngongo me te kore e whakawhāiti. 3M
He mea nui te mōhio ki te āhua oti e hiahiatia ana mō tētahi wāhanga, nā te mea he maha ngā wā ka hiahiatia he wāhanga hou hei taurite ki ngā mea o mua.
He rauemi utu nui te kowiri tira, nō reira he mea nui te whiriwhiri tupato i ngā taputapu whakaoti. Mā te tautoko tika mai i ngā kaiwhakarato ka āwhina i ngā toa ki te kimi huarahi hei penapena wā me te moni.
