I te ao o te miihini me te mahi whakarewa, he mea tino nui te tika me te pūmau. Ko tētahi o ngā taputapu nui o tēnei mara ko te taputapu, e whakamahia ana hei hanga miro ā-roto i roto i ngā momo rauemi. He tino rongonui ngā taputapu porowhita maitai tere-teitei (HSS) mō tōna whai huatanga me tōna roa. I roto i tēnei tuhinga, ka rukuhia e mātou te ao o ngā taputapu porowhita HSS, me te arotahi ki ngā taputapu pūwāhi ISO UNC, ngā taputapu porowhita UNC 1/4-20, me ngā taputapu pūwāhi porowhita UNC/UNF.
Akohia ngā taputapu porowhita HSS
Ko ngā taputapu porowhita maitai tere-rahi he taputapu tapahi e whakamahia ana hei hanga miro ā-roto i roto i ngā momo rauemi, tae atu ki ngā konganuku, ngā kirihou me te rakau. Kua hangaia ēnei taputapu hei whakamahi me ngā taputapu pato, ngā kī pato rānei, ā, e wātea ana i roto i ngā rahi me ngā koki rerekē hei whakatutuki i ngā tono rerekē.
Te pato i te tohu ISO UNC
Kua hangaia ngā taputapu tohu UNC ISO hei hanga miro e tutuki ana i te paerewa miro Unified National Coarse (UNC) e ai ki te whakamāramatanga a te International Organization for Standardization (ISO). Ko ēnei taputapu ka whakamahia i roto i ngā tono e hiahia ana ki ngā miro kaha, pono hoki, pērā i ngā ahumahi motuka me te rererangi. Hei tauira, ko te taputapu porowhita UNC 1/4-20 he mea hanga motuhake hei mīhini i ngā miro he 1/4-inihi te whānui, ā, e 20 ngā miro mō ia inihi, e pai ai mō ngā tono maha.

Ngā taputapu pito porowhita UNC/UNF
Ko ngā taputapu porowhita UNC/UNF tētahi atu taputapu porowhita maitai tere-teitei e whakamahia whānuitia ana i roto i te ahumahi. He hoahoa pito porowhita kei roto i ēnei taputapu e āwhina ana ki te tango pai i ngā maramara me ngā paru mai i te kōhao i te mea ka tapahia e te taputapu ngā miro. Ka whakaitihia hoki e tēnei hoahoa te taipana e hiahiatia ana hei taputapu i ngā kōhao, kia tere ake ai, kia whai hua ake ai hoki te tukanga. Ko ngā taputapu porowhita UNC/UNF e whakamahia ana i roto i ngā taiao whakaputa nui te rahinga e tino hiahiatia ana te tere me te tika.
Ngā painga o ngā taputapu porowhita maitai tere-teitei
He maha ngā painga o ngā taputapu porowhita HSS i ērā atu momo taputapu. Tuatahi, ko te maitai tere-rahi he momo maitai taputapu e mōhiotia ana mō tōna pakeketanga me tōna ātete ki te kakahu, ā, he mea tino pai mō ngā āhuatanga uaua o te mahi taputapu. Hei tāpiri, ko te hoahoa porowhita o ēnei taputapu ka āwhina i te neke i ngā maramara me ngā paru mai i te kōhao, ka whakaiti i te tūponotanga o te pakaru o te taputapu, ā, ka whakarite kia ma, kia tika hoki ngā miro. Mā te whakakotahitanga o ēnei āhuatanga ka waiho ngā taputapu porowhita maitai tere-rahi hei whiringa rongonui mō ngā momo mahi.
Ngā Tikanga Pai mō te Whakamahi i ngā Taputapu Porowhita HSS
Hei whakarite i ngā hua pai rawa atu ina whakamahia ngā taputapu porowhita maitai tere-rahi, he mea nui kia whai i ētahi tikanga pai. Tuatahi, me whakamahi i te rahi me te teitei tika o te taputapu mō te tono o nāianei. Mā te whakamahi i te taputapu hē ka pakaru pea ngā miro, ā, ka iti iho te kounga o te hua whakamutunga. Hei tāpiri, he mea nui kia whakamahia te wai tapahi tika hei whakahinuhinu i te taputapu me te whakaiti i te waku i te wā e pato ana. Mā tēnei ka roa ake te ora o te taputapu, ā, ka whakarite kia ma, kia tika hoki ngā miro.
