CNC milling: what materials can be used

CNC milling is a mechanical machining process in which a CNC (Computer Numerical Control) machine is used to remove material from a blank to create a desired shape. CNC milling allows you to obtain precise and repeatable results thanks to the automatic guidance of the movement of the workpiece and the tool.

Let's see together the materials that can be used for this type of processing
