Igikorwa cyo gutunganya ibice bya CNC kirimo guhinduranya, gusya, gucukura, gukata, nibindi, bishobora gukoreshwa mubikoresho bitandukanye, birimo ibyuma, plastike, ibiti, nibindi. Kubera ibyiza byo gutunganya neza, ibice bya CNC bigira uruhare runini uruhare mu kirere, gukora imodoka, ibikoresho bya elegitoronike, ibikoresho byubuvuzi, nizindi nzego. Ntabwo aribyo gusa, ibice bya CNC nabyo birerekana ubushobozi bwiyongera mubice bitari gakondo nko gukora ibihangano, ibikoresho byabigenewe, intoki, nibindi.
