Knee Assembly

Assembly

The bracket that slides up and down the column to set table height. The knee is the defining feature of this mill type: raising it brings the work toward the cutter, which sets the depth of cut and adapts to tools and parts of different heights. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
