He momo taputapu mīhini whānui te mīhini mira, ka taea e te mīhini mira te tukatuka i te papa (papa whakapae, papa poutū), te awaawa (ara kī, awaawa T, awaawa hiku kuru, me ētahi atu), ngā wāhanga niho (taputapu, pou spline, sprocket), te mata porowhita (miro, awaawa porowhita) me ngā momo mata. Hei tāpiri, ka taea hoki te whakamahi mō te miihini me te tapahi i te mata me te kōhao o roto o te tinana hurihuri. I te wā e mahi ana te mīhini mira, ka tāutahia te mea mahi ki runga i te tēpu mahi, ki ngā taputapu tuatahi rānei, ko te hurihanga o te kaitapahi mira te nekehanga matua, ā, mā te nekehanga whāngai o te tēpu, o te pane mira rānei, ka taea e te mea mahi te whiwhi i te mata miihini e hiahiatia ana. Nā te mea he tapahi maha-taha kore haere, ka nui ake te hua o te mīhini mira. Ki te kī ngāwari, he taputapu mīhini te mīhini mira mō te mira, te keri me te keri i te mea mahi.
Hītori whanaketanga:
Ko te mīhini mira te mīhini mira whakapae tuatahi i hangaia e te Amerikana a E. Whitney i te tau 1818. Hei mira i te awaawa porowhita o te mata whiri, i hangaia e te Amerikana a JR Brown te mīhini mira whānui tuatahi i te tau 1862, koinei te tauira o te mīhini mira mō te tēpu hiki. I te tau 1884 pea, ka puta mai ngā mīhini mira gantry. I ngā tau 1920, ka puta mai ngā mīhini mira haurua-aunoa, ā, ka taea e te tēpu te whakaoti i te huringa aunoa o te "whāngai - tere" me te "whāngai tere" me te aukati.
I muri i te tau 1950, i tino tere te whanaketanga o te mīhini mira i roto i te pūnaha whakahaere, ā, nā te whakamahinga o te mana mamati i tino whakapai ake te taumata o te aunoatanga o te mīhini mira. Ina koa i muri i te tekau tau atu i 1970, kua whakamahia te pūnaha whakahaere mamati o te tukatuka iti me te pūnaha whakawhiti taputapu aunoa i roto i te mīhini mira, ā, kua whakanuia ake te whānuitanga tukatuka o te mīhini mira, ā, kua pai ake te tika me te whai huatanga o te tukatuka.
I te kaha haere tonu o te tukanga mīhini, ka tīmata te whakamahinga whānui o te hōtaka NC i roto i ngā mahi taputapu mīhini, ā, ka tino tukuna te hunga mahi. Ka āta whakakapia te mahi ā-ringa e te hōtaka CNC mō ngā mīhini mira. Ka nui ake te uaua o ngā kaimahi, ā, ka nui ake te whai hua.
