3-axis CNC milling

Machining where a workpiece is processed by a rotating tool with computer controlled movement in 3 axes.

The process

The workpiece is clamped onto a flat table and processed by a rotating tool provided with cutting inserts. Positioning of tools and/or work table is done by a CNC program which controls the drive in the X, Y and Z directions. In this way, the tool can be moved along the bottom or on the workpiece surface. The inserts removes material by chip breaking.

The clamping in combination with the three axes provides a limited possibility of processing several sides without reclamping.

Through a variety of milling tools many forms and complex shapes can be created. Many controlled machines are also equipped with a tool magazine with automatic tool change.
