About the Rectangle Rigid Mill Column Bases
This is the rigid column base that comes on the NexGen mill and the Rigid Column Upgrade for the 5000/5400-series mill.
If you are upgrading your 2000-series mill to the 5800-series NexGen XY base you will also need this part to replace the round column base of the Z-axis on your mill. The short base is the same height as the regular 2000-mill round column. The tall column is the same height as the 2000 round column with the riser block in place. If you are looking for a rigid column base to add to your 2000-series mill you would order the round rigid column base instead of this rectangle base.
Installation Orientation of the Rigid Column Base
When it is mounted, the step on the boss should be to the front of the machine (see picture below). This will give you an additional ¼” of Y-axis travel more than the 2000 column.
