Izingxenye ze-CNC ziyizingxenye ezikhiqizwa ngomshini wokulawula izinombolo zekhompiyutha (CNC), futhi zidlala indima ebalulekile ezimbonini nasezinsizeni ezahlukahlukene. Lezi zingxenye zingabandakanya izingxenye ezifakwe ngomshini zezinto ezihlukahlukene zensimbi nezingezona ezensimbi, njengama-alloys e-aluminium, insimbi, amapulasitiki, njll. Ubuchwepheshe bemishini ye-CNC bungafinyelela ukunemba okuphezulu, ukucubungula ukuma okuyinkimbinkimbi, ngakho izingxenye ze-CNC zisetshenziswa kabanzi ku-aerospace, izimoto, impahla yezokwelapha, izinto zikagesi kanye neminye imikhakha.
