A CNC milling head is a type of vertical turning tool that provides cutting action by rotating. It is a special type of mechanical device that performs the operation of cutting and/or engraving materials at high speeds, high feeds and large depths
The head is mounted on a rotary table which allows it to move up and down in relation to the workpiece. The table can be rotated 360 degrees around its axis so different parts can be cut from a single piece of material
The head consists of two major components: the spindle (the shaft), which holds the cutting tool, and the leadscrews, which transmit rotational force from the spindle to the cutting tool(s).
