Poraka Ine Tika

Ko tētahi āhuatanga nui o ngā poraka ine ko te taea te hono atu me te iti rawa o te koretake o te āhua. Ka honoa ngā poraka mā te tukanga reti e kiia nei ko te whakakoi, e meinga ai ō rātou mata tino papatahi kia piri tahi. Ka taea te whakamahi i tētahi iti o ngā poraka ine hei hanga i ngā roa tika i roto i te whānuitanga whānui. Mā te whakamahi i ngā poraka e 3 i te wā kotahi i tangohia mai i tētahi huinga o ngā poraka e 30, ka taea te hanga i tētahi o ngā roa 1000 mai i te 3.000 ki te 3.999 mm i roto i ngā hikoinga 0.001 mm (0.3000 ki te 0.3999 inihi rānei i roto i ngā hikoinga 0.0001 inihi). I hangaia ngā poraka ine i te tau 1896 e te mīhini Huitene a Carl Edvard Johansson. Ka whakamahia ēnei hei tohutoro mō te whakatikatika i ngā taputapu ine e whakamahia ana i roto i ngā toa mīhini, pērā i ngā maikiromita, ngā pae sine, ngā calipers, me ngā tohu mata (ina whakamahia i roto i te mahi tirotiro). Ko ngā poraka ine te huarahi matua mō te paerewa roa e whakamahia ana e te ahumahi.
