What's Metal CNC Machining?
Metal CNC machining is the process of shaping metal blanks through operations such as cutting, milling, and turning using computer-controlled machine tools to achieve high-precision, complex components. It serves as the foundation of modern manufacturing, enabling the economical and efficient production of metal parts from prototypes to high-volume batches.
Types of Metal CNC Machining

Metal CNC Turning
The most common method, which using rotating cutting tools to remove material from a work piece, suitable for complex contours and cavities.

Metal CNC Milling
The work piece rotates while the tool moves linearly, ideal for cylindrical and conical parts.

Metal CNC Drilling
Used for creating holes and threads.

Wire EDM
Used for machining conductive metals with high hardness or complex geometries.
