Introduction to Vertical Machining. Vertical Machining has been around in its most basic form for more than 150 years. Yet, it's still one of the newest forms of machining technology (turning/lathes is the oldest). The process of "milling" entails a rotating cutter, or drilling bit, and a movable work table, which the workpiece is affixed to.
