He aha te Tapahi Maroke mō te Mea Whakarewa?

Te Mārama ki ngā Kani Porowhita

E ai ki te ingoa, ka whakamahia e te kani porowhita he mata rite ki te kōpae hei tapahi rauemi. He pai tēnei momo kani mō te tapahi whakarewa nā te mea ka taea e tōna hoahoa te tapahi tika tonu. Hei tāpiri, mā te nekehanga porowhita o te mata ka hangaia he mahi tapahi tonu, ka taea ai te tapahi i ngā konganuku rino me ngā konganuku kore-rino. Ko te tapahi maroke he tikanga tapahi whakarewa me te kore e whakamahi i te wai whakamatao. Engari i te whakamahi i te wai hei whakaiti i te wera me te waku, ka whakawhirinaki te tapahi maroke ki ngā mata he mea hanga mai i te rauemi ka taea te tu atu i te wera me te waku e hangaia ana e te konganuku. I te nuinga o te wā, ka whakamahia ngā mata taimana mō te tapahi maroke nā te mea he pakeke, he roa hoki.

Ka nui te wera e puta mai i ngā mata kani porowhita e whakamahia ana mō ētahi kani whakarewa i te wā e tapahi ana i te maitai porowhita, te konumohe me ētahi atu rauemi motuhake; engari i ētahi wā me pupuri te mea kua kanihia me te mata kani kia matao. I tēnei wā, ka oti te kani mā te mata kani porowhita motuhake, arā, he kani matao.

Ko te mea ngaro o te kaha o te kani matao ki te pupuri i te mea mahi me te mata kani kia matao ko te pane tapahi motuhake: he pane tapahi cermet.

Ka mau tonu ngā āhuatanga o ngā pane tapahi cermet i ngā uku pērā i te pakeketanga teitei, te kahatanga teitei, te ātete ki te kakahu, te ātete ki te pāmahana teitei, te ātete ki te waikura me te pumau matū, ā, he pai te pakari me te kirihou o te konganuku. He pai ngā painga o te cermet i te konganuku me te uku. He iti te kiato, he pakeketanga teitei, he ātete ki te kakahu me te kawe wera pai. Kāore e pakarukaru i te whakamatao ohorere, i te wera rānei. I te wā e tapahi ana, ka kawe te wera o ngā niho o te pane tapahi uku ki ngā maramara, kia noho matao ai te mata kani me te rauemi tapahi.

Ngā Painga o te Kani Matao

Ka taea te whakamahi i ngā kani matao mō te tapahi i ngā āhua maha, tae atu ki ngā tokotoko, ngā ngongo, me ngā mea e whakaputa ana. He pai te mahi a ngā kani matao porowhita aunoa, kua katihia, mō ngā mahi whakaputa me ngā kaupapa auau e hira ana te manawanui me te whakaotinga. Ka tukuna e ēnei mīhini te tere mata rerekē me ngā tere whāngai ka taea te whakarerekē mō te whakaputa tere teitei me te tapahi tika, kore-pūwero. Ka taea e ngā kani matao te miihini i te nuinga o ngā koranu rino me te kore-pūwero. Ko ētahi atu painga ko te iti o te whakaputa pūwero, te iti o ngā mura, te iti o te tae, me te kore puehu.

Ka taea e te tukanga kani matao te whakaputa i te kaha nui ki runga i ngā konganuku nunui me ngā konganuku taumaha — i ētahi wā, tae noa ki te ±0.005” (0.127 mm) te manawanui. Ka taea te whakamahi i ngā kani matao hei tapahi i ngā konganuku rino me ngā konganuku kore-rino, me ngā tapahi tika me ngā tapahi koki. Hei tauira, he pai ngā momo maitai noa mō te kani matao, ā, ka taea te tapahi tere me te kore e whakaputa i te nui o te wera me te waku.

Ngā Huakore o ngā Kani Makariri

Heoi, kāore te kani matao i te pai mō ngā roa kei raro iho i te 0.125” (3.175 mm). Hei tāpiri, ka taea e te tikanga te whakaputa i ngā pūwero taumaha. Ina koa, he raruraru tēnei ina he iti iho ngā OD i te 0.125” (3.175 mm) me ngā ID tino iti, ina katia te ngongo e te pūwero i hangaia e te kani matao.

Ko tētahi atu ngoikoretanga o ngā kani matao ko te pakeketanga o ngā mata kani ka pakarukaru, ka pāngia hoki e te ru. Ahakoa te nui o te wiri — hei tauira, nā te kore e ranea te pupuri i te wāhanga, nā te tere whāngai hē rānei — ka ngāwari te kino o ngā niho kani. Hei tāpiri, he nui te ngaronga o te kerf i ngā kani matao, ā, ka ngaro te mahi whakaputa me te piki ake o ngā utu.
Ahakoa e taea ana te whakamahi i te kani matao hei tapahi i te nuinga o ngā konganuku rino me ngā konganuku kore-rino, kāore i te tūtohutia mō ngā konganuku tino mārō — inā koa, ko ngā mea mārō atu i te kani tonu. Ahakoa ka taea e ngā kani matao te tapahi paihere, ka taea anake te mahi pēnā me ngā wāhanga iti rawa te diameter, ā, me whai taputapu motuhake.

Ngā Mata Mārō mō te Tapahi Tere

Ka whakamahia e te kani matao he mata porowhita hei tango i te rauemi, me te whakawhiti i te wera e puta ana ki ngā maramara e hangaia ana e te mata kani. Ka whakamahia e te kani matao he mata maitai tere-teitei totoka (HSS) he mata tungsten carbide-tipped (TCT) rānei e huri ana i ngā RPM iti.
He rerekē ki te ingoa, he onge te whakamahinga o ngā mata HSS i ngā tere tino teitei. Engari, ko tō rātou āhuatanga matua ko te pakeke, e homai ana ki a rātou he ātete nui ki te wera me te kakahu. He nui ake te utu o ngā mata TCT engari he tino pakeke hoki, ā, ka taea te mahi i ngā pāmahana teitei ake i te HSS. Mā tēnei ka taea e ngā mata kani TCT te mahi i ngā tere tere atu i ngā mata HSS, ka tino whakaiti i te wā tapahi.

He tere te tapahi, kāore e nui te wera me te waku, ā, ka ātete ngā mata o te mīhini kani makariri ki te pakaru wawe ka pā ki te mutunga o ngā wāhanga kua tapahia. Hei tāpiri, ka taea te whakakoi anō i ngā momo mata e rua, ā, ka taea te whakamahi i ngā wā maha i mua i te maka atu. Mā te roa o te ora o te mata ka āwhina i te kani makariri hei tikanga utu-pai mō te tapahi tere me ngā whakaotinga kounga teitei.

Ngā Hapa Noa hei Ārai i te Tapahi Maroke i te Mea Whakarewa

I te mea he mārō ake te mata o te tapahi i te mea whakarewa, ka uaua pea ki ō taputapu te tapahi maroke. Hei karo i ngā pakaru, i ngā aituā rānei i te wā e tapahi ana i te mea whakarewa, anei ētahi hapa noa hei tirotiro māu:

Te Tere Hē o te Mata: Ina tapahi maroke koe i te mea whakarewa, he mea nui kia aro ki te tere o te mata. Ki te tere rawa te haere o tō mata, ka piko, ka piko rānei te mea whakarewa, ka whati hoki tō mata. I tētahi atu taha, ki te puhoi rawa te neke, ka nui haere te wera i roto i tō kani, ā, ka kino pea.

Te Here Hē: Kia mau te here o te mea whakarewa e tapahia ana e koe. He mea morearea te neke i ngā mea, ā, ka pā he kino nui.

I te wā e whakamahi ana i tētahi mīhini kani matao, he mea nui kia whiriwhiria te teitei o ngā niho tika mō te rauemi e tapahia ana.

Ko te whiriwhiri i te teitei o ngā niho tino pai mō tō mata kani makariri ka whakawhirinaki ki:

* Te pakeke o te rauemi

* Te rahi o te wāhanga

* Te matotoru o te pakitara

Ko ngā wāhanga totoka me whai mata he piko niho matotoru, ko ngā ngongo pakitara angiangi, ko ngā āhua rānei he iti ngā piko whakawhiti me whai mata he piko angiangi. Mēnā he maha rawa ngā niho i roto i te rauemi i te wā kotahi, ko te mutunga he haehae, ehara i te tango maramara. Ka hua ake tēnei i te pikinga nui ake o te ahotea kutikuti.

I tētahi atu ringa, ina tapahia ngā pakitara taumaha, ngā mea totoka rānei mā te whakamahi i te niho tino angiangi, ka porowhita ngā maramara ki roto i te korokoro. Nā te mea he iti ngā korokoro o ngā niho-angi, ka nui ake ngā maramara kua kohia i te kaha o ngā korokoro, ā, ka pēhi ki ngā pakitara o ngā mahi, ka piri, ka mau hoki ngā maramara. Ka tīmata te mahi a te mata kani makariri me te mea kāore e tapahia ana, engari nā te mea kāore e taea te ngau i ngā korokoro kua piri. Ki te akiakihia te mata kia puta, ka pāngia koe e te tapahi ngoikore, ka nui ake te ahotea kutikuti, ā, i te mutunga ka pakaru pea tō mata kani makariri.

Kia mōhio mai, ahakoa he mea nui te whiriwhiri i te papa niho tika mō tō tono, ehara i te mea koinei anake te mea e whakatau ana i te mata kani makariri pai rawa atu mō tō tono. Pērā i ētahi atu taputapu, ko te whai huatanga me te roa o te wā o te kani makariri e whakawhirinaki ana ki te kounga o ngā wāhanga matua pērā i te mata. Ka hokona e HERO ngā mata kani makariri pai rawa atu nā te mea e whakamahi ana mātou i ngā mīhini tohunga i hangaia e Tiamana hei hanga i ā mātou hua. Ka āwhina ā mātou mata i a koe ki te tapahi i te konganuku mō ngā kaupapa maha. Ka koa mātou ki te āwhina mā te waea!
