What Is CNC Milling?

CNC milling removes material from a fixed workpiece using a rotating multi-tooth cutter. The cutter moves along X, Y, and Z axes (3-axis), or with a rotary table (4-axis), or two rotary axes (5-axis) for complex geometry.

We operate 3, 4, and 5-axis vertical machining centers (VMC) and horizontal machining centers (HMC) from Brother, Mazak, and Haas. Tolerance ±0.005 mm, MOQ 1 piece, lead time 3–7 business days.
