Hei whakarite i te tika o te whakakorenga, ka horoia e ngā tohunga hangarau ngā hononga roa o ngā wāhanga rino kowiri tira mā te hiko. He whakaahua nā Walter Surface Technologies.
Whakaarohia tētahi kaihanga e uru ana ki tētahi kirimana e pā ana ki te hanga kowiri tira matua. Ka tapahia, ka pikohia, ka whakarewahia ngā wāhanga pepa whakarewa me ngā ngongo i mua i te taunga ki tētahi teihana whakaoti. Ko te wāhanga he pereti kua whakarewahia poutū ki te ngongo. He pai te āhua o ngā whakarewa, engari ehara i te mea tino tika e rapuhia ana e te kiritaki. Nō reira, ka pau te wā o te mīhini huri ki te tango i te konganuku whakarewa nui atu i te tikanga. Kātahi, aue, ka puta mai ētahi kikorangi motuhake ki te mata - he tohu mārama o te nui rawa o te wera e whakaurua ana. I tēnei take, ko te tikanga kāore te wāhanga e tutuki i ngā whakaritenga a te kiritaki.
He maha ngā wā ka mahia ā-ringa, ā, me whai pūkenga me te pūkenga te huri me te whakaoti. Ka nui te utu mō ngā hapa whakaoti, i runga i te uara katoa kua hoatu ki te mea mahi. Ka nui ake pea te tāpiri i ngā rauemi utu nui e pāngia ana e te wera pērā i te maitai kore waikura, te mahi anō me ngā utu tāutanga para. I te taha o ngā raruraru pērā i te poke me te kore e taea te whakakore, ka taea e te mahi maitai kore waikura te huri hei mahi ngaro moni, hei mahi kino rānei e kino ai te ingoa.
Me pēhea te ārai a ngā kaihanga i ēnei mea katoa? Ka taea e rātou te tīmata mā te whakawhanake i ō rātou mōhiotanga ki te huri me te whakaoti, me te mārama ki ngā mahi a ia tangata, me te pānga ki ngā mea mahi kowiri tira.
Ehara ēnei i te kupu taurite. Ina hoki, he rerekē te whāinga o ia tangata. Mā te huri ka tangohia ngā rauemi pēnei i ngā pūwero me te konganuku whakarewa nui, ko te whakaotinga ka hoatu he whakaotinga ki te mata konganuku. He mārama te whakapoauau, i te mea ko te hunga e huri ana me ngā wira huri nui ka tere te tango i te nui o te konganuku, ā, mā te mahi pera ka waiho he karawarawa hohonu. Engari i roto i te huri, he pānga noa iho ngā karawarawa; ko te whāinga he tango wawe i te rauemi, inā koa ka mahi me ngā konganuku tairongo wera pēnei i te maitai kore waikura.
Ka oti te whakaoti i ngā taahiraa, ka tīmata te kaiwhakahaere me te kirikiri nui ake, ka ahu whakamua ki ngā wira huri pai ake, ngā mea whakakoi kore-whatu, me te kakahu huruhuru me te whakapiri whakakanapa pea hei whakatutuki i te whakaotinga whakaata. Ko te whāinga kia tutuki i tētahi whakaotinga whakamutunga (tauira rakuraku). Ka tangohia e ia taahiraa (te kirikiri pai ake) ngā karawarawa hohonu ake mai i te taahiraa o mua, ka whakakapia ki ngā karawarawa iti ake.
Nā te mea he rerekē ngā whāinga o te huri me te whakaoti, he maha ngā wā kāore e tautoko tetahi i tetahi, ā, ka taea te whakataetae tetahi ki tetahi mēnā ka whakamahia te rautaki paunga hē. Hei tango i te konganuku whakarewa nui, ka whakamahia e ngā kaiwhakahaere ngā wira huri hei hanga i ngā karawarawa hohonu rawa, kātahi ka tukuna te wāhanga ki tētahi tākai, ā, me whakapau kaha ia ki te tango i ēnei karawarawa hohonu. Ko tēnei raupapa huri-ki-te-whakaoti pea te huarahi tino whai hua ki te whakatutuki i ngā whakaritenga whakaoti a te kiritaki. Engari anō, ehara i te mea he tukanga tautoko.
Ko ngā mata mahi i hangaia mō te hangahanga, kāore e hiahiatia he huri me te whakaoti. Ko ngā wāhanga kua hurihia ka mahi i tēnei nā te mea ko te huri te huarahi tere ki te tango i ngā whakapiringa, i ētahi atu rauemi rānei, ā, ko ngā karawarawa hohonu i mahue mai i te wira huri koia tonu te mea e hiahiatia ana e te kiritaki. Ko ngā wāhanga e hiahia ana kia whakaotia anake ka hangaia i roto i te huarahi kāore e hiahiatia he tango rauemi nui. Ko tētahi tauira noa ko te wāhanga kowiri tira me te whakapiringa ataahua kua āraia ki te hau tungsten me whakaranu noa me te whakataurite ki te tauira whakaoti o te papa.
Ka raru pea ngā mahi a ngā huri me ngā wira tango-iti ina mahi ana me te maitai kore waikura. Waihoki, ka taea e te wera rawa te whakakorikori i te mata, ka huri hoki i ngā āhuatanga o te rauemi. Ko te whāinga kia mau tonu te mātao o te maitai kore waikura puta noa i te tukanga.
Hei whakatutuki i tēnei, he pai te whiriwhiri i te wira huri me te tere tango tere rawa atu mō te tono me te tahua. He tere ake te huri o ngā wira zirconia i te alumina, engari i te nuinga o te wā, ko ngā wira uku te mea pai rawa atu.
He āhua motuhake te pakaru o ngā matūriki uku tino pakari, koi hoki. I a rātou e memeha haere ana, kāore e huri papatahi, engari he koi tonu te mata. Ko te tikanga ka taea e rātou te tango tere i te rauemi, he maha ngā wā he poto noa iho te wā o ētahi atu wira huri. Nā tēnei ka tika te utu mō ngā wira huri uku. He pai rawa atu ēnei mō ngā tono kowiri tira nā te mea ka tere te tango i ngā maramara nunui, ā, ka iti ake te wera me te hē o te whakaputa.
Ahakoa ko tēhea wira huri e whiriwhiria ana e te kaihanga, me maumahara ki ngā poke pea. E mōhio ana te nuinga o ngā kaihanga kāore e taea e rātou te whakamahi i te wira huri kotahi ki te maitai waro me te maitai kore waikura. He maha ngā tāngata e wehewehe ā-tinana ana i ā rātou mahi huri waro me te maitai kore waikura. Ahakoa ngā mura iti o te maitai waro e taka ana ki runga i ngā mahi maitai kore waikura ka raru pea te poke. He maha ngā ahumahi, pērā i ngā ahumahi rongoā me ngā ahumahi karihi, me whakatauria ngā taonga pau he kore parahanga. Ko te tikanga o tēnei me tata kore (iti iho i te 0.1%) o te rino, te whanariki me te haurore) i roto i ngā wira huri mō te maitai kore waikura.
Kāore e taea e ngā wira huri te huri i a rātou anō; me whai taputapu hiko. Ka taea e te tangata te whakanui i ngā painga o ngā wira huri, o ngā taputapu hiko rānei, engari ko te mea pono ko ngā taputapu hiko me ā rātou wira huri he pūnaha kotahi. Kua hangaia ngā wira huri uku mō ngā huri koki me te nui o te mana me te taipana. Ahakoa he rite ngā whakaritenga e tika ana mō ētahi huri hau, ko te nuinga o te huri wira uku ka mahia me ngā taputapu hiko.
Ahakoa ngā mīhini huri kāore i te rawaka te kaha me te taipana, ka raru pea ngā mahi a ngā mīhini huri, ahakoa ngā mīhini whakakoi matatau rawa atu. Nā te kore o te kaha me te taipana, ka pōturi te mahi a te taputapu i raro i te pēhanga, ā, ka kore e taea e ngā matūriki uku i runga i te wira huri te mahi i tā rātou i hanga ai: te tango tere i ngā konganuku nunui, ā, ka whakaiti i te nui o ngā rauemi wera e uru ana ki te wira huri.
Ka whakanui ake tēnei i tētahi huringa kino: Ka kite ngā kaiwhakahaere huri i te rauemi kāore e tangohia, nō reira ka pana kaha ake rātou, ka puta he wera nui me te kikorangi. Ka mutu, ka pana kaha rawa atu rātou ka kanapa ngā wira, ka kaha ake tā rātou mahi, ka nui ake te wera i mua i te mōhio me whakakapi ngā wira. Ki te mahi pēnei koe i runga i ngā ngongo angiangi, i ngā pepa rānei, ka mutu ka haere tika atu rātou i roto i te rauemi.
Ae, ki te kore ngā kaiwhakahaere e whakangungua tika, ahakoa ngā taputapu pai rawa atu, ka taea e tēnei huringa kino te puta, inā koa ka pā ki te pēhanga e tukuna ana e rātou ki te mea mahi. Ko te mahi pai ko te whakatata atu ki te whakatauranga iahiko ingoa o te huri. Mena kei te whakamahi te kaiwhakahaere i te huri 10 amp, me pēhi kaha kia kaha te huri kia tata ki te 10 amp te hiko.
Mā te whakamahi i te āmita ka taea te whakarite i ngā mahi huri mēnā he nui te rino kore utu nui e tukatukahia ana e te kaihanga. He pono, he iti noa ngā mahi e whakamahi ana i te āmita i ia wā, nō reira ko te mea pai ko te whakarongo pai. Ki te rongo te kaiwhakahaere, ā, ki te rongo hoki i te hekenga tere o te RPM, tera pea kei te kaha rawa tana pana.
He uaua te whakarongo ki ngā pā e māmā rawa ana (arā, he iti rawa te pēhanga), nō reira, i tēnei wā, mā te aro ki te rere o te mura ka āwhina. Mā te huri i te maitai kore waikura ka puta he mura pouri ake i te maitai waro, engari me kitea tonu, me puta mai i te wāhi mahi i runga i te āhua ōrite. Ki te kite ohorere te kaiwhakahaere i te iti ake o ngā mura, tera pea nā te mea kāore i te nui te pēhanga, kāore rānei i te whakakikoruatia te wira.
Me pupuri hoki e ngā kaiwhakahaere he koki mahi ōrite. Ki te whakatata atu rātou ki te mea mahi i te koki tata-papatahi (tata ki te whakarara ki te mea mahi), ka nui te werawera; ki te whakatata atu rātou i te koki teitei rawa (tata ki te poutū), ka tūpono rātou ki te keri i te taha o te wira ki roto i te konganuku. Ki te whakamahi rātou i te wira Momo 27, me whakatata atu rātou ki te mahi i te koki o te 20 ki te 30 nekehanga. Ki te mea he wira Momo 29 ā rātou, me tata ki te 10 nekehanga te koki mahi.
Ko ngā wira huri momo 28 (whakawhāiti) e whakamahia ana mō te huri i ngā mata papatahi hei tango i ngā rauemi i ngā ara huri whānui. Ka pai ake hoki te mahi a ēnei wira whakawhāiti i ngā koki huri iti (tata ki te 5 nekehanga), nō reira ka āwhina i te whakaiti i te ngenge o te kaiwhakahaere.
Ka puta mai tētahi atu āhuatanga nui i tēnei: ​​te whiriwhiri i te momo wira huri tika. He pūwāhi whakapā tō te wira Momo 27 i runga i te mata whakarewa; he rārangi whakapā tō te wira Momo 28 nā tōna āhua kōniko; he mata whakapā tō te wira Momo 29.
Ko ngā wira Momo 27 tino noa ka taea te mahi i roto i ngā mahi maha, engari nā te āhua o te wira he uaua ki te whakahaere i ngā wāhanga he kōtaha hohonu me ngā piko, pērā i ngā huihuinga whakarewa o ngā ngongo maitai kore waikura. Mā te āhua kōtaha o te wira Momo 29 ka māmā ake te huri i ngā mata piko me ngā mata papatahi mā ngā kaiwhakahaere. Mā te wira Momo 29 tēnei e mahi mā te whakanui ake i te horahanga pa o te mata, ko te tikanga kāore e hiahiatia ana e te kaiwhakahaere te whakapau i te wā roa ki te huri i ia wāhi – he rautaki pai mō te whakaiti i te wera e puta mai ana.
Ina hoki, e pā ana tēnei ki tētahi wira huri. I te wā e huri ana, kaua te kaiwhakahaere e noho ki te wāhi kotahi mō te wā roa. Me kī kei te tango te kaiwhakahaere i te konganuku mai i tētahi wāhanga e hia putu te roa. Ka taea e ia te whakahaere i te wira i roto i ngā nekehanga poto ki runga, ki raro, engari mā te mahi pera ka wera rawa te mea mahi nā te mea ka puritia e ia te wira ki tētahi wāhi iti mō ngā wā roa. Hei whakaiti i te wera e uru mai ana, ka taea e te kaiwhakahaere te whakawhiti i te whakarewa katoa i te taha kotahi e tata ana ki tētahi matimati, kātahi ka hiki ake i te taputapu (me hoatu he wā ki te mea mahi kia whakamatao) ka whakawhiti i te mea mahi i te taha kotahi e tata ana ki tētahi atu matimati. Ka mahi ētahi atu tikanga, engari kotahi te āhuatanga e rite ana i a rātou katoa: ka karo i te wera nui mā te pupuri i te wira huri kia neke.
Ka āwhina hoki ngā tikanga "kāri" e whakamahia whānuitia ana ki te whakatutuki i tēnei. Mehemea kei te huri te kaiwhakahaere i tētahi hononga whakarewa i roto i te tūranga papatahi. Hei whakaiti i te ahotea wera me te keri nui rawa, i karohia e ia te pana i te huri i te taha o te hononga. Engari, ka tīmata ia i te pito ka tōia te huri i te taha o te hononga. Mā tēnei ka ārai hoki i te wira kei keri nui rawa ki roto i te rauemi.
Ae, ka wera rawa te konganuku i tētahi tikanga mēnā ka puhoi rawa te mahi a te kaiwhakahaere. Mēnā ka puhoi rawa, ka wera rawa te konganuku i te mahi a te kaiwhakahaere; mēnā ka tere rawa, ka roa pea te huri. Me whai wheako te kimi i te tere whāngai tika. Engari mēnā kāore te kaiwhakahaere i te mōhio ki te mahi, ka taea e rātou te huri i te para kia "mārama" ai te tere whāngai tika mō te mahi kei te ringa.
Ko te rautaki whakaoti e aro ana ki te āhua o te mata o te rauemi i tōna taenga mai me tōna wehenga atu i te tari whakaoti. Tāutuhia te tīmatanga (te āhua o te mata kua whiwhi) me te mutunga (me whakaoti), kātahi ka whakatakoto mahere hei kimi i te ara pai i waenganui i aua pūwāhi e rua.
He maha ngā wā, kāore te ara pai e tīmata me te kirikiri tino kaha. Tērā pea he rerekē te āhua o tēnei. Nā te mea, he aha e kore ai e tīmata ki te onepu matotoru hei hanga i te mata taratara, kātahi ka neke ki te onepu pai ake? Kāore ianei e tino koretake te tīmata me te kirikiri pai ake?
Kāore i te tino hiahiatia, engari he pānga anō tēnei ki te āhua o te kohikohinga. I te taenga o ia taahiraa ki tētahi kirikiri iti ake, ka whakakapia e te whakamahana ngā karawarawa hohonu ake ki ngā karawarawa papaku ake, angiangi ake. Ki te tīmata me te pepa kirikiri 40-kirikiri, te kōpae hurihuri rānei, ka waiho he karawarawa hohonu ki runga i te konganuku. He pai ki te mea ka whakatata mai aua karawarawa i te mata ki te mutunga e hiahiatia ana; koia te take e wātea ai aua taputapu whakaoti kirikiri 40. Heoi, ki te tono te kiritaki i tētahi whakaotinga Nama 4 (whakaotinga paraihe aronga), ka roa te wā ki te tango i ngā karawarawa hohonu i hangaia e te karawarawa Nama 40. Ka heke iho ngā kāpata i roto i ngā rahi kirikiri maha, ka roa rānei te wā ki te whakamahi i ngā karawarawa pai hei tango i aua karawarawa nui me te whakakapi ki ngā karawarawa iti ake. Ehara i te mea kāore i te whai hua katoa tēnei, engari ka nui rawa te wera e uru mai ana ki roto i te mea mahi.
He pono, he puhoi te whakamahi i ngā kirikiri kirikiri pai ki runga i ngā mata taratara, ā, ki te kore e pai te mahi, ka nui rawa te wera e puta mai ana. Koinei te wāhi ka taea e te kōpae e rua-i-te-kotahi, e whakarara ana rānei te kōpae hei āwhina. Kei roto i ēnei kōpae ngā kakahu kirikiri me ngā rauemi maimoatanga mata. Mā ēnei ka taea e te kāpata te whakamahi i ngā kirikiri hei tango i te rauemi, me te waiho hoki i te mutunga maeneene.
Ko te taahiraa e whai ake nei i roto i te whakaotinga whakamutunga ko te whakamahi i ngā mea kore-whatu, e whakaatu ana i tētahi atu āhuatanga ahurei o te whakaotinga: ka pai te mahi a te tukanga me ngā taputapu hiko tere-rerekē. Ka mahi pea te huri koki matau e rere ana i te 10,000 RPM me ētahi rauemi huri, engari ka rewa pai ētahi mea kore-whatu. Mō tēnei take, ka whakaitihia e ngā kaiwhakaoti te tere ki waenga i te 3,000 me te 6,000 RPM i mua i te tīmatanga o te taahiraa whakaoti me ngā mea kore-whatu. Ko te tikanga, ko te tere tika e whakawhirinaki ana ki te tono me ngā mea pau. Hei tauira, ko ngā pahu kore-whatu ka huri i waenga i te 3,000 me te 4,000 RPM, ko ngā kōpae maimoatanga mata ka huri i waenga i te 4,000 me te 6,000 RPM.
Mā te whai i ngā taputapu tika (ngā huri tere rerekē, ngā momo rauemi whakaoti rerekē) me te whakatau i te maha o ngā hikoinga tino pai ka puta he mahere e whakaatu ana i te ara pai i waenga i te rauemi e haere mai ana me te rauemi kua oti. He rerekē te ara tika i runga i te tono, engari ka whai ngā kaitapahi mohio i tēnei ara mā te whakamahi i ngā tikanga kuti rite.
Ka whakaotihia te mata o te kowiri tira e ngā roera kore-whatu. Mō te whakaotinga whai hua me te roa o te whakamahinga, ka rere ngā momo rauemi whakaoti rerekē i ngā RPM rerekē.
Tuatahi, ka ata haere rātou. Mēnā ka kite rātou i tētahi mea angiangi o te maitai kore waikura e wera haere ana, ka mutu tā rātou whakaoti i tētahi wāhi ka tīmata i tētahi atu wāhi. Tērā pea kei te mahi rātou i ngā taonga rerekē e rua i te wā kotahi. Ka mahi paku rātou i tētahi, kātahi ki tētahi, kia wātea ai te wā o tētahi atu mea ki te whakamatao.
Ina whakakanapahia kia rite ki te āhua whakaata, ka taea e te kaikanapa te whakakanapa whakawhiti ki te pahu whakakanapa, ki te kōpae whakakanapa rānei, i te ahunga poutū ki te taahiraa o mua. Mā te whakakanapa whakawhiti ka kitea ngā wāhi e hiahia ana kia whakaranua ki te tauira karawarawa o mua, engari kāore tonu e tae ki te mata kia rite ki te āhua whakaata o te Nama 8. Kia tangohia ngā karawarawa katoa, me whakamahi he kakahu huruhuru me te wira whakakanapa hei hanga i te āhua kanapa e hiahiatia ana.
Hei whakatutuki i te whakaotinga tika, me whakarato ngā kaihanga i ngā taputapu tika ki ngā kaiwhakaoti, tae atu ki ngā taputapu me ngā pāpāho tuturu, tae atu ki ngā taputapu whakawhitiwhiti kōrero, pērā i te whakatū tauira paerewa hei whakatau i te āhua o tētahi whakaotinga. Mā ēnei tauira (kei te taha o te tari whakaotinga, i roto i ngā tuhinga whakangungu, me ngā tuhinga hokohoko) ka āwhina i te katoa kia kotahi te whakaaro.
Mō ngā taputapu tuturu (tae atu ki ngā taputapu hiko me ngā mea whakakoi), ka raru pea te āhua o ētahi wāhanga ahakoa mō ngā kaimahi tino mātau o te tari whakaoti. Koinei te wāhi e taea ai e ngā taputapu ngaio te āwhina.
Me kī me whakaoti e te kaiwhakahaere he huihuinga ngongo angiangi he kowiri tira. Mā te whakamahi i ngā kōpae taupoki, i ngā pahu rānei ka raru pea, ka wera rawa, ā, i ētahi wā ka hanga he wāhi papatahi ki runga i te ngongo tonu. I konei, ka taea e ngā mīhini huri whitiki i hangaia mō ngā ngongo te āwhina. Ka takai te whitiki kawe i te nuinga o te diameter o te paipa, ka horahia ngā pūwāhi whakapā, ka whakanui ake i te pai me te whakaiti i te whakauru wera. Heoi anō, pērā i ngā mea katoa, me neke tonu te mīhini huri whitiki ki tētahi atu wāhi hei whakaiti i te nui o te wera me te karo i te kikorangi.
Pērā anō hoki mō ētahi atu taputapu whakaoti ngaio. Whakaarohia he mīhini huri whitiki matihao i hangaia mō ngā wāhi kuiti. Tērā pea ka whakamahia e te mīhini huri hei whai i te hononga o te taura i waenganui i ngā papa e rua i te koki koi. Engari i te neke poutū i te mīhini huri whitiki matihao (pērā i te paraihe i ō niho), ka nekehia whakapaetia e te mīhini huri whitiki matihao i te pito o runga o te hononga taura, kātahi ki te pito o raro, me te whakarite kia kaua te mīhini huri maihao e noho roa ki roto.
Ko te whakarewa, te huri me te whakaoti i te maitai kore waikura ka puta mai tētahi atu raruraru: te whakarite kia tika te whakakorenga. Whai muri i ēnei whakararuraru katoa ki te mata o te rauemi, kei reira ētahi poke e toe ana hei aukati i te paparanga chromium o te maitai kore waikura kia puta noa i te mata katoa? Ko te mea whakamutunga e hiahiatia ana e te kaihanga ko te amuamu a te kaihoko riri mō ngā wāhanga waikura, poke rānei. Koinei te wāhi e whai wāhi ai te horoi tika me te whai i ngā mea e tika ana.
Ka taea e te horoi hikohiko te āwhina i te tango i ngā poke kia tika ai te whakakorenga, engari āhea me mahi tēnei horoinga? Kei te tono te tikanga. Mena ka horoi ngā kaihanga i te maitai kore waikura hei whakatairanga i te whakakorenga katoa, ka mahia tonutia e rātou i muri i te whakarewanga. Ki te kore e pena, tera pea ka kohia e te rauemi whakaoti ngā poke mata mai i te mea mahi ka horahia ki hea atu. Heoi, mō ētahi tono nui, ka whiriwhiri pea ngā kaihanga ki te whakauru i ētahi atu mahi horoi—tērā pea ka whakamātautau mō te whakakorenga tika i mua i te wehenga atu o te maitai kore waikura i te papa wheketere.
Me kī, ka whakarewahia e te kaihanga tētahi wāhanga kowiri tira nui mō te umanga karihi. Ka whakatakotoria e te kaiwhakarewa pewa hau tungsten ngaio tētahi hononga dime e āhua pai ana. Engari anō, he tono nui tēnei. Ka whakamahia e tētahi kaimahi i te tari whakaoti he paraihe e hono ana ki tētahi pūnaha horoi hikohiko hei horoi i te mata o tētahi whakarewa. Kātahi ka pania e ia te matimati whakarewa mā te whakamahi i tētahi kakahu kore-whatu me te kakahu whakakakahu, ā, ka oti katoa te paraihe kia ōrite. Kātahi ka tae mai te paraihe whakamutunga me tētahi pūnaha horoi hikohiko. Whai muri i te noho mō te rā kotahi, e rua rānei, whakamahia he taputapu whakamātautau ringaringa hei whakamātautau i te wāhanga mō te tika o te whakakorenga. Ko ngā hua, i tuhia me te pupuri tahi me te mahi, i whakaatu kua whakakorea katoatia te wāhanga i mua i tōna wehenga atu i te wheketere.
I te nuinga o ngā whare hanga, ko te huri, te whakaoti me te horoi i te korekore maitai ka mahia i raro iho i te wai. Inaa, ka mahia i mua tata tonu i te tukunga o te mahi.
Ko ngā wāhanga kua oti hē te hanga ka puta ko ētahi o ngā para me ngā mahi anō tino utu nui, nō reira he mea tika kia tirohia anō e ngā kaihanga ā rātou tari huri me te whakaoti. Mā ngā whakapainga ki te huri me te whakaoti ka āwhina i te whakaiti i ngā arai nui, te whakapai ake i te kounga, te whakakore i ngā āwangawanga, ā, ko te mea nui, ka whakapiki ake i te pai o te kiritaki.
Ko FABRICATOR te maheni matua o te umanga hanga me te hanga whakarewa o Amerika Te Raki. Ka whakaratohia e te maheni ngā purongo, ngā tuhinga hangarau me ngā hītori take e āhei ai ngā kaihanga ki te mahi i ā rātou mahi me te whai hua ake. Kua mahi a FABRICATOR ki te umanga mai i te tau 1970.
Nā te urunga katoa ki te putanga mamati o The FABRICATOR, he māmā noa iho te uru atu ki ngā rauemi whai hua o te ahumahi.
Kua taea te uru atu ki te putanga mamati o The Tube & Pipe Journal, e whakarato ana i te urunga māmā ki ngā rauemi whai hua o te ahumahi.
Kia pai te urunga katoa ki te putanga matihiko o STAMPING Journal, e whakarato ana i ngā whanaketanga hangarau hou, ngā mahi pai me ngā purongo ahumahi mō te mākete tā whakarewa.
Inaianei kua uru katoa ki te putanga mamati o The Fabricator en Español, he māmā noa iho te uru atu ki ngā rauemi ahumahi whai hua.
