Vertical Milling Machines — Vertical machining centers are often preferred for flat parts that must have through holes. Fixtures for these parts are more easily designed and built for a vertical spindle. Also, the thrust of the cut developed in drilling or in milling pockets can be absorbed directly by the bed of the machine.

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.
