Ko te Mīhini CNC e pā ana ki te mīhini whakarewa me ngā taputapu mīhini CNC, ko te mīhini CNC he tikanga hanga whakarewa e whakahaeretia ai ngā mīhini e te waehere whakatū i te wā o te tukanga whakaputa. Ka whakamahia e ngā ratonga mīhini CNC TTM ngā tikanga hanga tango, arā, ka tangohia ngā rauemi i te tukanga whakaputa, he rerekē tēnei i te hanga tāpiri (pēnei i te tā 3D). Ka whakamahia e ngā ratonga mīhini CNC TTM te hangarau hanga hou hei whakarato i ngā mahi mira me te huri hei whakarite i ngā hua pai mō te mīhini tino tika.
