CNC machining, iyo inonziwo precision machining, isimbi yekucheka kana kubvisa maitiro neComputerized Numberical Control (CNC kwenguva pfupi). Inobatsirwa neCNC kuti isvike pakakwirira uye yakatsiga chokwadi nemutengo wakaderera wevashandi. Precision machining ndeipi nzira dzakasiyana siyana umo chidimbu chezvakagadzirwa (kazhinji vanenge vachikanda blanks, forged blanks kana zvimiro zvesimbi zvinhu) inochekwa kuita inodiwa yekupedzisira chimiro uye saizi neinodzorwa-yekubvisa zvinhu. Nepo iyo alloy simbi CNC machining zvikamu zviri zvimedu zvebasa zvakagadzirwa nesimbi yealloy (mumhando dzekukandira, forgings kana alloy simbi zvimiro) nemichina yeCNC.
