CNC milling yog tsim rau ntau yam ntaub ntawv, suav nrog ob qho tib si hlau thiab tsis yog -cov ntaub ntawv hlau.
Cov khoom siv hlau muaj xws li aluminium alloys, stainless hlau, carbon steel, thiab titanium alloys. Aluminium alloys yog cov khoom siv feem ntau vim lawv lub teeb yuag thiab yooj yim ntawm machining. Titanium alloys nquag siv nyob rau hauv aerospace teb; Txawm hais tias lawv nyuaj rau tshuab, lawv muaj kev ua tau zoo dua.
Hauv cov khoom tsis yog-hlau, yas (xws li ABS thiab nylon), cov ntaub ntawv sib xyaw, thiab cov yas engineering kuj tseem siv hauv CNC milling, tshwj xeeb tshaj yog nyob rau hauv prototyping thiab cov khoom tsim khoom hnyav.
