Milling machines are used to create three dimensional parts out of solid materials like wood, plastic and metal by removing material. Milling machines are either manually operated (for simple parts) or computer controlled (CNC) for complex and/or high precision parts. Unlike their larger counterparts, tabletop milling machines don't take up much room and are very affordable.
3-axis machining centers move a part in two directions, and the tool moves up and down (Z). 5-Axis machining centers can rotate on two additional rotary axes which help the cutting tool approach the part from all directions.
