What Is CNC Machining?

CNC (Computer Numerical Control) machining is a manufacturing process that uses computer-controlled machines to remove material from metal or plastic workpieces with high precision. Common CNC processes include milling, turning, drilling, tapping, and multi-axis machining.

Typical CNC machining applications include:

• Functional prototypes

• Precision components

• Low- to medium-volume production

• High-tolerance industrial parts
