Horizontal milling machines feature shorter and thicker tools capable of taking deeper cuts and removing more material than vertical milling machines. Vertical milling machines often use long cylindrical tools called end mills for more precise but shallower cuts on smaller workpieces. 3. Cutting Specifications and Accuracy

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.
