E hia ngā hurihanga hei kati i te takirere pūrerehua

Takirere pūrerehua ā-ringa

Ko te nuinga o ngā takirere pūrerehua ā-ringa ka kati mā te huri i te kakau, i te kakau rānei, ā, e rua ki te toru ngā hurihanga e hiahiatia ana kia kati katoa. Ko te kaupapa matua ko te whakarerekē i te āhua o te diameter mā te huri i te pereti pūrerehua mā te 90° pea (arā, he hurihanga hauwhā), engari nā te hoahoa o te hanganga tuku (pēnei i te taputapu noke), me huri haere ngā hurihanga mō te mahi tuturu.

Ko te hurihanga o te kakau i te taha matau te ahunga kati, ko te hurihanga i te taha maui te ahunga whakatuwheratanga.

‌Rārangi pūrerehua kakau‌Mā te huri i te kakau ka whakatuwheratia, ka kati hoki te takirere pūrerehua. He kōpae niho kei waenganui i te kakau me te tinana takirere, ā, ko te whānuitanga o te nekehanga o te kakau i runga i te kōpae niho kei waenganui i te 0~90°. Ina tū te kakau i te tūranga poutū me te paipa, ka kati te takirere; ina whakarara te kakau ki te paipa, ka tuwhera te takirere.

‌Taurere pūrerehua taputapu kutukutu‌Ka whakahaerehia te whakatuwheratanga me te katinga o te takirere pūrerehua mā te huri i te wira ringaringa i runga i te pane taputapu noke. Mā te huri i te wira ringaringa ki te taha matau ka taea te kati i te takirere pūrerehua, ā, mā te huri i te taha maui ka taea te whakatuwhera.

 

Ngā takirere pūrerehua motuhake, nui rānei

 

He iti noa iho ngā āhuatanga motuhake (pērā i ngā takirere ahumahi nui, ngā pūnaha tuku uaua rānei) e hiahia ana kia mano ngā hurihanga o te mahi. Hei tauira, i kīia i roto i ngā hua rapu me huri te takirere kia 8,000 ngā wā, engari ko ēnei āhuatanga kāore e pā ana ki ngā takirere pūrerehua, ā, he nui ake te tūponotanga ka uru mai ngā rerekētanga hoahoa o ngā takirere kuaha, o ētahi atu momo takirere rānei.

 

takirere pūrerehua hiko

Mena ka whakamahia he pūwhakaoho hiko, ka whakawhirinaki te tere kati ki te tere o te motuka (ko te tikanga he 12~48 rpm, ka taea e ngā hoahoa motuhake te neke atu i te 100 rpm)‌8. Heoi, ka pā noa tēnei tawhā ki te wā kati, ā, kāore he pānga ki te maha o ngā hurihanga o te mahi ā-ringa.

 

takirere pūrerehua hau

E 200 ki te 600 ngā hurihanga e hiahiatia ana hei kati i tētahi takirere pūrerehua. E tohu ana ngā whakaritenga whakahaere o ngā takirere pūrerehua tapahi tere hau kāore e tika kia nui rawa ngā hurihanga whakatuwhera me te kati, ā, me whakaoti hoki e ngā takirere whānui ngā mahi whakatuwhera me te kati i roto i te 200-600 ngā hurihanga.
