Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top of a workpiece.

Pin Mill Basics. Pin mills are available in two basic configurations: horizontal or vertical shaft. In a vertical shaft pin mill, as shown in Figure C, stationary pins are screwed or bolted onto a stationary disc (called a stationary mill plate), which is located above a rotating disc (called the rotor). Pins are also mounted on the grinding rotor.
