What is CNC milling?

Rotary cutting tools are used in CNC milling to remove material from a workpiece to produce finished parts and products. This manufacturing process is great for many materials, including metals, polymers, wood, and glass.

CNC milling systems generally have 3 linear axes: the X, Y, and Z axes. This allows for the highest precision and detail accuracy. In addition, Partsproto offers more advanced 5-axis systems, where the tool head and the machine bed are also rotatable.

With 5-axis CNC machines, parts with high geometric complexity can be manufactured without multiple machine setups.
