Contouring heads transform a horizontal boring mill’s W-axis quill motion into radial cutting edge motion, Inside each tool is an actuator shaft with an inclined key that precisely mates with a slot in a tool slide. Quill extension pushes the actuator shaft and causes the tool slide to move outward, increasing the diameter of the rotating cutting edge. Quill retraction decreases the cutting diameter.7 V!
