Abstract
A milling device includes a grinding member, a table, a plurality of actuators and a controller. The table has a grinding surface. The table is positioned adjacent to the grinding member such that the grinding surface faces toward at least a portion of the grinding member. The table and the grinding member at least partially define a grinding chamber sized and configured to receive material. Each actuator is connected to the grinding member such that movement of that actuator causes at least a portion of the grinding member to move from a raised position to a lowered position to grind the material. The controller is connected to the actuators and is configured to cause the actuators to move in a sequence that causes the grinding member to wobble as the grinding member is moved by the actuators to grind material.
