Ko te whiriwhiri i tētahi mata taimana ehara i te mea ko te whiriwhiri noa i te whānui tika me te tumanako ka murua koe e te kani. Me ōrite te mata ki te rauemi, ki te kani, ki te hohonu o te tapahi me ngā āhuatanga o te papa mahi. Ahakoa te āhua o te raima, te uku me ngā pereti whakapakari katoa he "mea mārō" mai i tawhiti, engari ki te mata taimana, he rerekē rawa te whanonga.
He māmā noa te ture matua: me ngawari ake te here o ngā rauemi pakeke, engari me pakari ake te here o ngā rauemi ngawari me ngā mea whakakoi. E whakamārama ana a Norton Abrasives i te kōwhiringa here mata taimana me te ariā hononga rerekē kotahi: he pai ngā hononga mārō mō ngā rauemi ngohengohe pērā i te uku, ko ngā hononga ngāwari ia he pai mō te raima mārō. He ahua tawhito i te tīmatanga, engari he mārama ina mahara koe me memeha te hononga whakarewa i te tere tika kia puta ai ngā taimana hou.
Ture tere: whiriwhiria te mata mā te rauemi i te tuatahi, kātahi ka whakaū i te momo here, te hoahoa wāhanga, te rahi kani, te hohonu tapahi me te whakamahinga mākū, maroke rānei.
| Rauemi | Mata e Manakohia ana | Momo Here | Tikanga Tapahi Pai rawa atu |
|---|---|---|---|
| Raima kua rongoatia | Mata taimana raima wehewehea | He hononga ngāwari ki te hononga waenga | Mākū, maroke rānei |
| Raina mārō | Mata raima hononga ngohengohe | Here ngohengohe | He pai ake te mākū |
| Raina matomato | Raima matomato, mata tīmatanga wawe rānei | Here mārō | Kei te momo kani |
| Āpara | Mata taimana uku | Here mārō | Mākū, maroke rānei |
| Papa whakapakari | Mata taimana raima whakapakaritia | He hononga ngāwari ki te hononga waenga | He pai ake te mākū |
| Raina me te rebar | Mata wehewehe i whakarewahia ki te laser | He hononga ngāwari ki te hononga waenga | He pai ake te mākū |
| Papa raima me te papa uku | Mata whakakotahi kua whakatauria | Herenga mārō-waenga | Ngā tapahi poto anake |
Whakamahia tēnei tūtohi hei tātari tuatahi. Ki te hiahia koe ki tētahi whakataurite hohonu ake i waenga i ngā rauemi papa, pānuihia tēnei aratohu i runga i te kōwhiringa o te mata kani raima me te uku Ko te whiringa mata whakamutunga ka whakawhirinaki tonu ki te whānui o te mata, te rahi o te rākau, te kaha o te kani, te hohonutanga tapahi, te whakatauranga RPM me te mea kei te wātea te wai.
He mārō te raima kua rongoatia, inā koa he kirikiri matotoru kei roto. Ka whakapōuri i ngā taimana e kitea ana, nō reira me iti noa te pakaru o te hononga kia kitea ai ngā taimana tapahi hou. Ko ngā aratohu mata taimana he tikanga mārō te raima i te 3,000 psi, iti iho rānei , ā, ko te raima i te 6,000 psi, neke atu rānei , he mārō ake. Mā tēnā ka whai wāhi pai ngā kaihangarau me ngā kaihoko ki te tīmatanga i mua i te tirotiro i te momo kirikiri me te whakakaha.
He ngawari ake te uku i te raima kua whakamaroketia, engari he kaha ake te whakakoi. Ka taea e te onepu me te kirikiri i roto i te uku te kai i te matua o te mata mena he hē te mata e whakamahia ana. Koia te take e whakamahia ai e te mata taimana mō te uku he here mārō me te tiaki i raro i te tapahi. I roto i te reo māmā o te papa mahi, ehara te uku i te "kuikui ngāwari". He mīhini huri mata e mau ana i te kākahu rori.
Ka tāpirihia e ngā pereti whakapakari tētahi atu raruraru: te maitai. Me kaha ngā wāhanga o te mata taimana mō te raima me te rebar, me te pēhanga whāngai pumau, me te whakamatao pai. Ko te tapahi mākū te kōwhiringa mohio ake nā te mea ka tere te wera o te pa ki te maitai.
| Momo Here | Pai rawa atu mō | Ki te whakamahia hē |
|---|---|---|
| Here ngohengohe | Raina kua whakamaroketia, raima mārō, raima whakapakaritia | Ka tere rawa te mau i roto i te uku |
| Herenga waenga | Mahi raima whānui me te mahi papa mahi whakauru | E whakaaetia ana, engari kāore i te tino pai i ngā wā katoa |
| Here mārō | Uku, raima matomato, poraka whakakoi | Ka taea te pania ki te raima mārō |
He mea nui anō hoki te kirikiri. E ai ki ētahi aratohu whiriwhiri mata, ko te kirikiri nui ake i te 3/4 inihi he kirikiri nui, ko te kirikiri kei raro iho i te 3/8 inihi he māmā ake te tapahi engari ka tere ake te pakaru o te mata. Koia te take ka taea tonu e ngā pereti e rua he rite te kaha pēhi te tapahi i ngā momo rerekē. He āhua whakakatakata te raima, ā, he maha ngā wā ka hunaia e ia i roto i te kirikiri.
Mō te raima kua rongoatia, tīmata ki te mata taimana raima kua wehea. Mena he mārō te raima, he tīmata rānei te mata ki te kanapa, neke atu ki te hononga ngohengohe. Mena he ngohengohe, he koi hoki te raima, neke atu ki te hononga mārō. Mō ngā kōwhiringa taputapu e pā ana, ka taea hoki e koe te tirotiro i te mata kani raima whārangi
Me ōrite hoki te whiriwhiringa o te mata kani raima ki te mata kani. Hei tauira, ko te Ngā āhuatanga o te Husqvarna K 770 Whakarārangihia he mata 14 inihi , he hōhonutanga tapahi mōrahi 5 inihi , he putanga 5 hp me te tere ā-taha mōrahi 18,000 fpm . He whakamaumahara ēnei tau ehara i te mea ko te rauemi anake te mea e whiriwhiria ai te mata. Me ōrite te diameter, te rahi o te arbor me te tere ki te mīhini.
Mō te tapahi uku, whakamahia he mata taimana uku motuhake. Me mārō te hononga, me pai te āputa paru, ā, me ārai i te tapahi raro. E kī ana a Norton ka taea e te tapahi raro te arahi ki te ngaronga o te wāhanga, ā, e taunaki ana ia kia tiakina te tapahi raro, kia nui ake rānei te rere o te wai ina pāngia te matua maitai e te rauemi whakakoi.
Mā te mata uku noa e whakaatu te motuhaketanga o ēnei taputapu. Kei te rārangihia e te CMT he mata uku 300 mm me te wāhanga 8 mm te matotoru , te whānui o te poka 20 mm me te tere mōrahi 6,400 rpm , ā, e tohu ana kāore e tika ana mō te raima, mō te raima whakapakari rānei. Mō ngā mahi papa uku, honoa te mata ki te kaitapa tika, pērā i te te tapahi raima penehīni mō te tapahi uku me te papa raima .
Mō te raima whakapakari, whakamahia he mata kua whakaritea mō te pānga ki te rebar. Mā te hononga ngawari ki te waenga ka āwhina i te mata ki te tapahi tonu i te raima mārō, ā, mā te hanganga wāhanga kaha ka āwhina i a ia kia ora i te wera me te pānga ina puta mai te maitai. He pai ake ngā wāhanga kua whakarewahia ki te laser mō te tapahi taumaha ake nā te mea he kaha ake te hononga wāhanga i raro i ngā āhuatanga uaua.
Kaua e akiaki i te mata ina tae ki te rino. Kia mau tonu te whāngai, whakamahia te wai ina taea, ā, kaua e takahuri te kani i te tapahi. Ki te tīmata te paowa o te mata, ki te pekepeke te kani, ki te tīmata rānei te kaiwhakahaere ki te kōrero ki te mīhini, kati ka tirotiro i te whakatakotoranga.
Ehara i te mea ko te roa o te mata anake te mea e pā ana ki te tapahi mākū. Aratohu hangahanga OSHA mō te silica Ka whakatakoto i te taumata mahi silica tioata e manawahia ana ki te 25 μg/m³ me te rohe whakaaturanga e whakaaetia ana ki te 50 μg/m³ , e rua hei toharite taumaha-wā 8-hāora. Nā reira ka taea te whakatau i te tapahi mākū hei whakatau whakahaere puehu me te whakatau whakamatao hoki.
He pai te tapahi maroke mō ngā tapahi poto me ngā mahi whakatika, engari me whakamahi noa i te mata kua tohua mō te whakamahinga maroke. Kaua rawa e whakamaroke i te mata makuku anake. Ehara tēnā i te mahi hanga-ā-mara; he ara tere tēnā ki te wera nui, ki te whakakanapa, ā, ka huri whakarere te mata hei konganuku para utu nui. Mō tētahi whakataurite mahi hohonu ake, pānuihia te tapahi raima mākū me te maroke .
Ahakoa he pai te mata o te kani i runga i te kani hē, kāore tonu e hua pai. I mua i te tapahi, whakaūtia te whānui o te mata, te rahi o te rākau, te RPM mōrahi, te hohonu o te tapahi, te whāngai wai me te kaha o te kani. Mena he tapahi roa te ara, he whakatikatika rori, he keri awa rānei mō ngā ratonga, mā tēnei aratohu me pēhea te whiriwhiri i te kani rori tika mō te tapahi raima me te uku koia te taahiraa pai ake e whai ake nei.
Mō ngā kaimahi kirimana e whakataurite ana i ngā mīhini, ko te he aratohu tino pai ki ngā mīhini tapahi raima me ngā mīhini tapahi rori ka nui ake te horopaki mō te momo mīhini, te hohonutanga o te tapahi me te mahi papa. Mena e hiahia ana koe ki tētahi tirohanga whānui ake, ko te tuhinga mō ngā painga o te kani rori mō te whakatikatika raima, uku me te papa rori he tohutoro ā-roto whai hua anō hoki.
Ko te hapa tuatahi ko te whakamahi i te mata kotahi mō te raima, te uku me ngā pereti whakakaha. Ko te tuarua ko te kore aro ki te pakeke o te hononga. Ko te tuatoru ko te whakapae i te kani ina ko te raruraru tūturu ko te karaihe mata, te RPM hē, te whakamatao ngoikore, te taurite rauemi hē rānei.
Ki te mutu te tapahi o te mata taimana, tirohia te hononga, te rauemi, te tere o te kani me te puna wai i mua i te pana kaha. Me tapahi te mata pai me te pēhanga pumau. Ki te mea me tohe koe ki te kani, tera pea kei te kōrero te mata ki a koe i tetahi mea. Mō taua hapa motuhake, whakamahia tēnei aratohu ki runga te whakakanapa i te mata taimana me te take e mutu ai te tapahi o te mata .
Whakamahia he tūtohi whiriwhiri mata taimana hei whakawhāiti i te kōwhiringa, kātahi ka whakaū i ngā mea e whā: te rauemi, te here, te taurite kani me te tikanga tapahi. Mō te raima, whakaarohia te kaha me te kirikiri. Mō te uku, whakaarohia te pakū me te tiaki i te tapahi iti. Mō ngā pereti whakapakari, whakaarohia te maitai, te wera me te whakamatao.
Ehara i te mea ka tere ake te tapahi o te mata matau. Ka mātao ake te mahi, ka roa ake te mahi, ka whakaiti i te wā kore mahi, ā, ka rite te āhua o te kaiwhakahaere me te mea kua whakamaheretia e ia ngā mea katoa i te tīmatanga.
