Product Description

This is the rigid column base that comes on the NexGen mill and the Rigid Column Upgrade.

If you are upgrading your 2000-series mill to the 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, with a standard 14″ base, you would order the Round Rigid Column Base instead of this rectangle base.

NOTE: The rigid column bases are designed to work with the rigid column arm and cannot be adapted to the standard column on a 5000 or 5400 series mill.

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.

Red arrow indicates the front of the column base. The tall Mill Column Base shown for reference.
