He aha ngā tikanga matua me ngā mahi mō te miihini i ngā mata o ngā niho?ngā taputapu porowhita porowhita?

1. **Ngā Tikanga Mīhini**

He maha ngā tikanga matua mō te miihini i ngā taputapu porowhita porowhita:

**Mira**: Koinei te tikanga tuku iho, ka whakamahia he taputapu mira hei tapahi i te mata niho porowhita i runga i te taputapu parakore. He pai ake te mira engari he iti ake te tika.

**Te Huri**: Ko te huri he whakamahi i te wira huri hei whakaoti i ngā mata niho o te taputapu. Ka whakarei ake tēnei tukanga i te tika me te kounga o te mata o te taputapu, ka hua ake he pai ake te mahi whatunga me te roa ake o te ora ratonga.

**Mīhini CNC**: Nā te whanaketanga o te hangarau CNC, kua noho te mīhini CNC hei tikanga nui mō te hanga taputapu porowhita. Mā tēnei ka taea te hanga taputapu tino tika me te tino whai hua, inā koa mō ngā āhua niho uaua.

**Te Mīhini Whakaputa**: Ka whakamahia e tēnei tikanga matatau ngā taputapu whakaputa (pērā i ngā taputapu mira porowhita, ngā oumu rānei) hei hanga i te mata o te niho mā te nekehanga whanaunga i waenga i te taputapu me te taputapu kore. Ka tutuki i tēnei tikanga te mīhini mata niho tino tika.

 

2. **Ngā Taputapu Mīhini**

Ko ngā taputapu e whai ake nei e hiahiatia ana mō te porowhitataputapu pikote miihini:

**Mīhini Mira Taputapu Whakarara**: Whakamahia mō ngā mahi mira, ka tapahia e te taputapu tapahi mira te mata niho porowhita i runga i te taputapu papatahi.

**Mīhini Huri Taputapu Porowhita**: Whakamahia mō ngā mahi huri, ka whakaotia e te wira huri ngā mata niho o te taputapu.

**Pokapū Mīhini CNC**: Whakamahia mō te mīhini CNC, e āhei ai te hanga taputapu tino tika me te tino whai hua.

**Ngā Taputapu Mīhini Whakaputa**: Ko ngā mīhini pēnei i a Gleason, Oerlikon rānei, he mea hanga motuhake mō te whakaputa mīhini o ngā taputapu porowhita.

 

3. **Ngā Hipanga Mīhini**

Te miihini o te porowhitataputapu pikoKo ngā mahi matua o te mata o ngā niho ko ēnei:

(1) **Te Hanganga Pātea**

**Kōwhiringa Rauemi**: Ko ngā maitai koranu kaha teitei, pērā i te 20CrMnTi, 20CrNiMo rānei, e whakamahia whānuitia ana. He pai te pakari o ēnei rauemi, ā, he ātete ki te kakahu.

**Tukatuka Pātea**: Ka hangaia te pātea taputapu mā te hanga, mā te whakarewa rānei kia tutuki ai tōna rahi me tōna āhua i ngā whakaritenga.

 

(2) **Te Mīhini Taratara**

**Mira**: Ka whakanohoia te mea para ki runga i te mīhini mira, ā, ka whakamahia he taputapu tapahi mira hei tapahi i te mata niho porowhita tuatahi. Ko te tika o te mira he tata ki te Tau 7 ki te 8.

**Hobbing**: Mō ngā taputapu he nui ake te tika o ngā whakaritenga, ka taea te whakamahi i te hobbing. Ko te hobbing he nekehanga whanaunga i waenga i te hob me te taputapu kore e whakamahia hei hanga i te mata niho porowhita.

 

(3) **Whakaoti Mīhini**

**Te Huri**: Whai muri i te mahi miihini taratara, ka whakanohoia te taputapu ki runga i te mīhini huri, ā, ka whakamahia he wira huri hei whakaoti i ngā mata o ngā niho. Ka taea e te huri te whakapai ake i te tika me te kounga o te mata o te taputapu, ā, ko te tika ka eke ki te Tau 6 ki te 7.

**Mīhini Whakaputa**: Mō ngā taputapu porowhita porowhita tino tika, ka whakamahia te mīhini whakaputa. Ka hangaia te mata o te niho mā te nekehanga whanaunga i waenga i te taputapu whakaputa me te taputapu kore.

 

(4) **Te Maimoatanga Wera**

**Te Whakatio**: Hei whakarei ake i te pakeketanga me te ātete ki te kakahu o te taputapu, ka mahia te whakatio. Ka taea e te pakeketanga o te mata o te taputapu i muri i te whakatio te eke ki te HRC 58 ki te 62.

**Whakamahana**: Ka whakamahanatia te taputapu i muri i te tineia hei whakamama i te ahotea tineia me te whakapai ake i te pakari.

 

(5) **Tirohanga Whakamutunga**

**Tirotiro Tika o te Mata Niho**: Ka whakamahia ngā pokapū ine taputapu, ngā taputapu ine taputapu whatu rānei hei tirotiro i te tika o ngā mata niho, tae atu ki te hapa kōtaha niho, te hapa ahunga niho, me te hapa koki porowhita.

**Aroturukitanga Mahi Hononga**: Ka whakahaerehia ngā whakamātautau hononga hei aromatawai i te mahi hononga o te taputapu, kia mōhio ai kei te pai te mahi me te pono o te tuku i te wā e whakamahia ana.

 

4. **Te Arotau i ngā Tukanga Mīhini**

Hei whakapai ake i te kounga me te whai huatanga o te miihini taputapu porowhita, me whakapai ake te tukanga miihini:

**Te Kōwhiringa Utauta**: Ka whiriwhiria ngā taputapu e tika ana i runga i te rauemi taputapu me ngā whakaritenga tika. Hei tauira, ka taea te whakamahi i ngā taputapu taimana, CBN rānei mō ngā taputapu tino tika.

**Te Arotau i ngā Tawhā Mīhini**: Mā te whakamātautau me te tātari whakatauira, ka arotauhia ngā tawhā mīhini pēnei i te tere tapahi, te tere whāngai, me te hohonu tapahi hei whakarei ake i te pai me te kounga o te mīhini.

**Mīhini Aunoa**: Mā te whakamahi i ngā taputapu mīhini aunoa, pērā i ngā pokapū mīhini CNC, i ngā raina whakaputa aunoa rānei, ka taea te whakapai ake i te pai me te ōrite o te mīhini.

 

He tukanga uaua te miihini i ngā mata niho taputapu porowhita e hiahia ana kia whai whakaaro ki ngā āhuatanga maha, tae atu ki ngā rauemi, ngā taputapu, ngā tukanga, me te tirotiro. Mā te arotau i ngā tukanga me ngā taputapu miihini, ka taea te hanga i ngā taputapu porowhita tino tika me te tino pono hei whakatutuki i ngā hiahia o ngā tono ahumahi rerekē.
