A polishing system for polishing a flat face of a rock comprises a polishing surface, a fence system, and a drive system. The polishing surface is supported for rotation about a primary rotation axis. The fence system is supported above the polishing surface. The drive system causes the polishing surface to rotate about the primary rotation axis and displace a driven portion of the fence system along a path relative to the primary rotation axis. The fence system engages the rock to prevent the polishing surface from causing the rock to move about the primary rotation axis and to cause the rock to move towards and away from the primary rotation axis. |
