What is CNC Milling?
CNC Milling (Computer Numerical Control Milling) is a subtractive manufacturing process that uses computerized controls and multi-axis rotating cutting tools to precisely remove material from a solid workpiece, transforming raw metal or plastic into high-precision, custom-engineered components.
Modern CNC milling operates along 3, 4, or 5 axes, enabling extreme accuracy with tight tolerances (up to $\pm0.005\text{ mm}$). It is ideal for complex geometries, rapid prototyping, and high-volume production in demanding industries like aerospace, automotive, medical devices, and consumer electronics. At WEHAO CNC, our advanced multi-axis milling centers deliver fast lead times, superior surface finishes, and factory-direct pricing for all your custom machining needs.
