CNC (computer numerical control) machining is a kind of subtractive manufacturing process, which uses automated, high-speed cutting tools to form designs from metal or plastic blanks. CNC machining processes usually include milling, turning, surface grinding and electrical discharge machining (EDM). CNC machining is used on many common metals such as aluminum, brass, mild and stainless steels, magnesium and titanium. It can also be used on rigid or engineering-grade plastic resins.
The geometric information of the part is provided by a computer-aided design (CAD) model. The skilled machinist operates the final part of the programmed tool path based on the CNC machine tool. CNC machine tools can cut almost any metal alloy and rigid plastic, with high precision and repeatability, making CNC machining parts suitable for almost all industries, including aerospace, medical, robotics, electronics and industry. Hunglik provides quotations for CNC machining of more than 40 materials, from commercial aluminum and acetals to advanced titanium and different kinds of engineering plastics.
