Trunion Table Assembly

The rotary table is 2" high and 4" (100mm) in diameter.

The main components have been machined from solid bar stock steel, and the complete unit weighs seven pounds. It features a 72-tooth worm gear.

To maintain the required degree of accuracy, the base of the rotary table and the worm housing are ground as a pair in the production process.

It would not be possible to maintain this level of accuracy if the CNC worm gear and ring gear were not simultaneously ground together.
