He maha ngā tāngata e hoko ana i te maitai kore waikura kua oti te mīhini, ka nui ake te uaua o ngā rauemi me whai whakaaro ngā kaiwhakahaere.
Pērā i te nuinga o ngā rauemi, he maha ngā painga me ngā ngoikoretanga o te maitai kore waikura. Ka kiia he "maitai kore waikura" te maitai mēnā kei roto i te koranu te 10.5% te iti rawa o te chromium, e hanga ana i tētahi paparanga waikura e ātete ana ki te waikawa me te waikura. Ka taea te whakapai ake i tēnei ātete waikura mā te whakanui ake i te ihirangi chromium me te tāpiri i ētahi atu kaihoko koranu.
Nā ngā āhuatanga "kowiri tira" o te rauemi, te iti o te tiaki, te pakari, me ngā momo whakaotinga mata, he mea pai mō ngā ahumahi pēnei i te hanga whare, ngā taonga whare, te kai me te inu, te hauora, me te maha atu o ngā tono e hiahia ana ki te kaha me te ātete ki te waikura pērā i te rino.
He nui ake te utu o te maitai kore waikura i ētahi atu maitai. Heoi, he pai te ōwehenga kaha-ki-taumaha, e āhei ai te whakamahi i ngā matotoru rauemi angiangi ki te whakaritea ki ngā momo noa, ka taea ai te penapena utu. Nā te utu whānui, me whakarite ngā toa kei te whakamahi rātou i ngā taputapu tika hei karo i te moumou utu nui me te mahi anō i tēnei rauemi.
Ko te maitai kore waikura he uaua ki te whakarewa nā te mea ka tere te mimiti i te wera, ā, me tino tupato i te wā whakaoti me te wā oro.
Ko te mahi me te maitai kore waikura he tikanga whānuitia me whai kaiwhakarewa, kaiwhakahaere rānei he nui ake te wheako i te mahi me te maitai waro, he mea e kaha ake ana te manawanui. Tērā pea ka whakaitihia tōna whānui ina whakauruhia ētahi tawhā, inā koa i te wā e whakarewa ana. Nā te nui o te utu o te maitai kore waikura, he mea tika kia whakamahia e ngā kaiwhakahaere he nui ake te wheako.
"Ko te tikanga ka hokona e te tangata te kowiri tira nā tōna āhua whakaoti," te kī a Jonathan Douville, te kaiwhakahaere hua matua mō te rangahau me te whanaketanga o te ao i Walter Surface Technologies i Pointe-Claire, Quebec. "Ka tāpiri atu tēnei ki ngā here me whai whakaaro ngā kaiwhakahaere."
Ahakoa he whakaotinga kakano raina rahi 4, he whakaotinga whakaata rahi 8 rānei, me whakarite te kaiwhakahaere kia whakautehia te rauemi, kia kore ai hoki e pakaru te whakaotinga i te wā e whakahaeretia ana, e tukatukahia ana hoki. Ka taea hoki e tēnei te whakawhāiti i ngā kōwhiringa mō te whakarite me te horoi, he mea nui ēnei hei whakarite kia pai te hanga wāhanga.
"I te wā e mahi ana koe me tēnei rauemi, ko te mea tuatahi me mahi ko te whakarite kia ma, kia ma, kia ma," te kī a Rick Hatelt, Kaiwhakahaere Whenua o Kanata mō PFERD Ontario, Mississauga, Ontario. "He mea tino nui kia whakarite kia ma (karekau he waro) te hau, kia horoia te maitai kore waikura hei tango i ngā poke ka puta ai te waikura i muri mai, ā, kia kaua e hangaia anō te paparanga whakangāwari, kia hangaia he paparanga tiaki hei whakaiti i te waikura."
Mēnā kei te whakamahia te kowiri tira, me horoi te rauemi me te taiao e karapoti ana. He pai te tango i te hinu me te toenga kirihou mai i ngā rauemi. Ka taea e ngā poke i runga i te kowiri tira te whakapōrearea, engari ka raru pea i te wā e whakarewa ana, ā, ka puta he hapa. Nō reira, he mea nui kia horoia te mata i mua i te tīmatanga o te whakarewa.
Ehara i te mea ko ngā taiao awheawhe te mea tino ma, ā, ka raru pea te whakawhiti-paru i te wā e mahi ana me te maitai kowiri tira me te maitai waro. He maha ngā wā ka whakahaerehia e te toa he maha ngā pā hau, ka whakamahia rānei ngā hauhautanga hei whakamatao i ngā kaimahi, ka taea e ēnei te pana i ngā paru ki runga i te papa, te maturuturu rānei, te hanga rānei i te hauhautanga ki runga i ngā rauemi mata. He tino uaua tēnei ina pupuhihia ngā matūriki maitai waro ki runga i te maitai kowiri tira. He rerekētanga nui te wehewehe i ēnei rauemi me te pupuri i a rātou ki roto i te taiao ma ina tae mai ki te whakarewanga whai hua.
He mea nui kia tangohia te tae o te mata kia kore ai e hanga waikura i roto i te wā, ā, kia kore ai e ngoikore te hanganga whānui. He pai hoki te tango i te kikorangi kia ōrite ai te tae o te mata.
I Kanata, nā te tino makariri me te rangi hotoke, he mea nui te whiriwhiri i te kounga tika o te maitai kore waikura. I whakamārama a Douville i te tīmatanga i whiriwhiria e te nuinga o ngā toa te 304 nā tōna utu. Engari, ki te whakamahia e te toa te rauemi i waho, ka tūtohu ia kia huri ki te 316, ahakoa he rua te utu. Ka pāngia te 304 e te waikura mēnā ka whakamahia, ka rongoatia rānei i waho. Ahakoa kua horoia te mata, ā, ka puta he paparanga pāhekoheko, ka pāngia te mata e ngā āhuatanga o waho, ka memeha te paparanga pāhekoheko, ā, ka mutu ka waikura anō.
"He mea nui te whakarite whakarewa mō ētahi take matua," te kī a Gabi Miholics, tohunga whakawhanake tono, Abrasive Systems Division, 3M Canada, Rānana, Ontario. "Me tango te waikura, te peita me ngā chamfers kia tika ai te whakarewa. Kaua he paru i runga i te mata whakarewa ka ngoikore ai te hononga."
E kī ana a Hatelt he mea nui te horoi i te wāhi, engari ko te whakarite i mua i te whakarewatanga ka uru pea ki te whakakoi i te rauemi kia tika ai te piri me te kaha o te whakarewa.
Mō te whakarewa maitai kore waikura, he mea nui kia whiriwhiria te konganuku whakakī tika mō te taumata e whakamahia ana. He tino tairongo te maitai kore waikura, ā, me whakamana ngā hononga whakarewa ki te momo rauemi kotahi. Hei tauira, me whakamahi te konganuku turanga 316 i te konganuku whakakī 316. Kāore e taea e ngā kaiwhakarewa te whakamahi noa i tētahi momo konganuku whakakī, me whai whakakī motuhake ia taumata maitai kore waikura mō te whakarewa tika.
"I te wā e whakarewahia ana te maitai kore waikura, me āta tirotiro te kaiwhakarewa i te pāmahana," te kī a Michael Radaelli, te kaiwhakahaere hua i Norton | Saint-Gobain Abrasives, Worcester, MA. "He maha ngā momo taputapu ka taea te whakamahi hei ine i te pāmahana o te whakarewa me te wāhanga i te wā e wera ana te kaiwhakarewa, nā te mea ki te mea he pakaru kei roto i te maitai kore waikura, kua pakaru te wāhanga."
I tāpiri atu a Radaelli me whakarite te kaiwhakarewa kia kaua ia e noho roa i te wāhi kotahi. He huarahi pai te whakarewa papa maha hei ārai i te wera nui o te papa. Mā te whakarewa roa o te maitai kore waikura turanga ka wera rawa, ka pakaru.
"Ka roa ake te wā e pau ana i te whakarewa ki te maitai kore waikura, engari he mahi toi anō hoki e hiahia ana ki ngā ringa mātau," te kī a Radaelli.
Ko te whakarite i muri i te whakarewanga e whakawhirinaki ana ki te hua whakamutunga me tōna whakamahinga. I ētahi wā, e ai ki tā Miholics, kāore te whakarewanga e kitea, nō reira he iti noa te horoinga i muri i te whakarewanga e hiahiatia ana, ā, ka tere te tango i ngā paru e kitea ana. Me whakataurite, me horoi rānei te whakarewanga, engari kāore e hiahiatia he whakaritenga mata motuhake. Mena e hiahiatia ana he whakaotinga pai, he whakaotinga whakaata rānei, me mahi pea ētahi atu mahi whakakanapa. Kei te whakamahinga anake.
"Ehara i te tae te raruraru," te kī a Miholics. "Ko te rerekētanga o te mata e tohu ana kua rerekē ngā āhuatanga o te konganuku, ā, ka taea te waikura/waikura."
Mā te whiriwhiri i tētahi taputapu whakaoti tere rerekē ka penapena wā me te moni, ā, ka taea hoki e te kaiwhakahaere te taurite i te whakaotinga.
He mea nui kia tangohia te tae o te mata kia kore ai e hanga waikura i roto i te wā, ā, kia kore ai e ngoikore te hanganga whānui. He pai hoki te tango i te kikorangi kia ōrite ai te tae o te mata.
Ka taea e te tukanga horoi te kino i ngā mata, inā koa ka whakamahia ngā matū kaha. Mā te horoi koretake ka ārai i te hanganga o tētahi paparanga kore e taea te whakamahi. Koia te take e taunaki ana te tini o ngā tohunga kia horoia ā-ringa ēnei wāhanga kua whakarewaina.
"Ina mahi koe i te horoi ā-ringa, ki te kore koe e tuku i te hāora kia tauhohe ki te mata mō ngā haora 24, 48 rānei, kāore he wā hei hanga i tētahi mata kore mahi," te kī a Douville. I whakamārama ia me whai hāora te mata kia tauhohe ki te chromium i roto i te koranu hei hanga i tētahi paparanga kore mahi. Ko ētahi toa ka horoi, ka tākai i ngā wāhanga ka tukuna tonutia, ka whakaroa i te tukanga, ka whakanui ake i te tūponotanga o te waikura.
He mea noa mā ngā kaihanga me ngā kaiwhakarewa te whakamahi i ngā rauemi maha. Heoi, e ai ki te kōrero i mua ake nei, ka tāpirihia e te whakamahinga o te maitai kore waikura ētahi herenga. He taahiraa tuatahi pai te tango i te wā ki te horoi i te wāhanga, engari ka rite te pai ki te taiao e noho ana ia.
I kī a Hatelt kei te kite tonu ia i ngā wāhi mahi poke. Ko te whakakore i te aroaro o te waro i roto i te taiao mahi kowiri tira te mea nui. Ehara i te mea onge mō ngā toa e whakamahi ana i te rino te huri ki te kowiri tira me te kore e whakarite tika i te taiao mahi mō tēnei rauemi. He hapa tēnei, ina koa mēnā kāore e taea e rātou te wehewehe i ngā rauemi e rua, te hoko rānei i ā rātou ake taputapu.
"Ki te mea he paraihe waea tāu hei huri, hei whakarite rānei i te maitai kore waikura, ā, ka whakamahia e koe ki te maitai waro, kāore e taea e koe te whakamahi i te maitai kore waikura i ēnei rā," te kī a Radaelli. "Kua poke ngā paraihe i te waro, ā, kua waikura. Kia poke whakawhiti ngā paraihe, kāore e taea te horoi."
Me whakamahi motuhake ngā toa i ngā taputapu hei whakarite rauemi, engari me tapa hoki ngā taputapu he "kowiri tira anake" hei karo i te poke koretake, e ai ki tā Hatelt.
Me whai whakaaro ngā toa mahi ki ngā āhuatanga maha i te wā e whiriwhiri ana i ngā taputapu whakarite whakarewa kowiri tira, tae atu ki ngā kōwhiringa whakamarara wera, te momo kohuke, te tere me te rahi o te kōhao.
"He tīmatanga pai te whiriwhiri i tētahi mea whakakoi me te paninga whakamarara wera," te kī a Miholics. "He tino mārō te maitai kore waikura, ā, ka nui ake te wera ka puta i te wā e huri ana i te maitai ngawari. Me haere te wera ki tētahi wāhi, nō reira he paninga e taea ai te rere o te wera ki te taha o te kōpae, kaua ki te noho noa ki te wāhi e huri ana koe. I taua wā, he mea tino pai."
Ko te whiriwhiri i tētahi mea whakakoi ka whakawhirinaki anō ki te āhua o te whakaotinga whānui, tāna tāpiri. Kei roto i te kanohi o te kaimātakitaki. Ko ngā kohuke alumina i roto i ngā mea whakakoi te momo tino noa e whakamahia ana i ngā mahi whakaotinga. Hei hanga i te maitai kore waikura kia kikorangi i runga i te mata, me whakamahi te kohuke silicon carbide. He koi ake, ā, ka waiho ngā tapahi hohonu ake e whakaata rerekē ana i te mārama, ka kikorangi. Mena kei te rapu te kaiwhakahaere i tētahi whakaotinga mata motuhake, ahurei rānei, he pai ake te kōrero ki te kaiwhakarato.
"He raru nui te RPM," te kī a Hatelt. "He rerekē ngā RPM e hiahiatia ana mō ngā taputapu rerekē, ā, he tere rawa te oma. Mā te whakamahi i te RPM tika ka pai ake ngā hua, e pā ana ki te tere o te mahi me te pai o te mahi. Kia mōhio koe ki te otinga e hiahiatia ana e koe me te pehea o te Ine."
I tāpiri atu a Douville ko te haumi ki ngā taputapu whakaoti tere-rerekē tētahi huarahi hei whakakore i ngā raruraru tere. He maha ngā kaiwhakahaere e whakamahi ana i te huri noa hei whakaoti, engari he tere teitei anake mō te tapahi. Me whakaroa te whakaoti i te tukanga. Mā te whiriwhiri i tētahi taputapu whakaoti tere-rerekē ka penapena wā me te moni, ā, ka taea e te kaiwhakahaere te whakataurite i te whakaoti.
He mea nui anō hoki te kirikiri ina whiriwhiria he kirikiri whakakoi. Me tīmata te kaiwhakahaere me te kirikiri pai rawa atu mō te whakamahinga.
Ka tīmata ki te kirikiri 60, 80 rānei (waenga), ka taea e te kaiwhakahaere te peke tonu ki te kirikiri 120 (pai) ki te kirikiri 220 (tino pai), ka hoatu ki te kowiri tira te mutunga Nama 4.
"E toru noa ngā taahiraa māmā," te kī a Radaelli. "Heoi, ki te mea he nui te mahi a te kaiwhakahaere, kāore e taea e ia te tīmata me te kirikiri 60, 80 rānei, ā, ka taea e ia te whakamahi i te kirikiri 24 (tino taratara) 36 rānei (taratara). Ka tāpirihia he taahiraa anō tēnei, ā, he uaua pea te tango i te rauemi. He hōhonu ngā karawarawa kei runga."
Hei tāpiri, ko te tāpiri i tētahi rehu ārai-piripiri, i tētahi kirikiri rānei, he hoa pai pea mā te kaiwhakarewa, engari he maha ngā wā ka warewarehia i te wā e whakarewa ana i te maitai kore waikura, e ai ki a Douville. Me tango ngā wāhanga he piripiri, ka taea e ēnei te rakuraku i te mata, te huri me ētahi atu mahi, ā, ka roa ake te wā e moumou ana. Ka taea te whakakore ngāwari i tēnei mahi mā te whakamahi i tētahi pūnaha ārai-piripiri.
